Morin, Nicolas. "Évaluation du POCIS (Polar Organic Chemical Integrative Sampler) : domaine de validité et performances pour 56 micropolluants organiques : application aux hormones, pharmaceutiques, alkyphénols, filtre UV et pesticides." Thesis, Lyon 1, 2013. http://www.theses.fr/2013LYO10056.
Full textAbstract:
Le POCIS (Polar Organic Chemical Integrative Sampler) est un outil d'échantillonnage intégratif alternatif aux techniques d'échantillonnages classiques (ponctuelle ou automatisée) dédié à la mesure de micropolluants organiques relativement hydrophiles dans les eaux. Cet outil permet d'intégrer les concentrations dans le temps (CTWA, Time-Weighted Average Concentration) et, dans certains cas, d'abaisser les limites de quantification. Une revue bibliographique détaillée a montré la forte variabilité des données de performances du POCIS mesurées en laboratoire (notamment les taux d'échantillonnage ou Rs). Cette variabilité résulte en majeure partie de systèmes expérimentaux d'étalonnage différents selon les études et pas toujours renseignés. Dans la littérature, les CTWA obtenues in situ sont comparées aux concentrations obtenues après échantillonnage classique, tel que mis en œuvre actuellement dans les programmes de surveillance européens ; ces concentrations sont dans la plupart des cas du même ordre de grandeur, même si elles ne représentent pas tout à fait la même information. Avec comme objectif d'obtenir des CTWA les plus justes et robustes possibles, nous avons étudié le comportement du POCIS « pharmaceutique » en laboratoire vis-à-vis de 56 micropolluants (hormones, pharmaceutiques, alkylphénols, pesticides, filtre UV), dans un système expérimental d'étalonnage conçu spécifiquement pour contrôler l'ensemble des conditions expérimentales ayant une influence sur les Rs. Nous avons ainsi déterminé 43 Rs robustes et démontré que le POCIS est bien adapté à l'échantillonnage de la plupart des molécules étudiées. De plus, l'allure des cinétiques d'accumulation est expliquée à l'aide des propriétés physico-chimiques des molécules (log D , surface polaire). Cinq homologues deutérés ont été identifiés en tant que PRC (Performance Reference Compounds), c'est-à-dire qu'ils peuvent être utilisés pour corriger les différences de conditions entre le laboratoire et le terrain. Nous avons également comparé le POCIS au Chemcatcher « polaire » en laboratoire et montré qu'en terme de domaine d'application et de performances, le POCIS est mieux adapté pour les micropolluants étudiés. Enfin, nous avons testé la justesse et la robustesse du POCIS lors de deux essais inter-laboratoires (EIL). Le premier EIL, portant sur l'étalonnage de l'outil en laboratoire, a démontré la robustesse de ses performances pour 3 pesticides. Le deuxième EIL in situ a démontré la pertinence du POCIS pour échantillonner des hormones, des pharmaceutiques et des pesticides dans un effluent de station d'épuration. Cette thèse permet d'avancer dans le domaine des connaissances sur l'outil POCIS et de favoriser son application dans le cadre de la directive sur l'eauThe POCIS (Polar Organic Chemical Integrative Sampler) is an alternative integrative sampling tool to conventional sampling methods (grab or automated) for measuring hydrophilic organic micropollutants in water. This tool permits to supply time-weighted average concentrations (TWAC) and, sometimes, to decrease limits of quantification. A detailed bibliographic review showed the important variability of POCIS performance data measured in laboratory (notably the sampling rates or Rs). This variability is in majority due to different experimental calibration systems, not always well detailed, among studies. In the literature, in situ TWAC are compared to concentrations from conventional sampling, actually used in European monitoring programs ; these concentrations are generally of the same order of magnitude, even if they do not represent the same information. In order to obtain accurate and robust TWAC, we studied in laboratory the “pharmaceutical” POCIS behavior for 56 micropollutants (hormones, pharmaceuticals, alkylphenols, pesticides, UV filter), in a calibration system specifically made for controlling the whole experimental conditions having an influence on Rs. We determined 43 robust RS and demonstrated that POCIS is well adapted for sampling most of studied molecules. Moreover, the pattern of kinetic accumulations is explained using molecule physical-chemical properties (log D, polar surface). Five deuterated homologues were identified as PRCs, meaning that they can be used for correcting differences in conditions between the laboratory and the field. We also compared the POCIS with the “polar” Chemcatcher and we showed that in term of application field and performances, the POCIS is better adapted for studied micropollutants. At last, we tested the accuracy and the robustness of the POCIS during two inter-laboratory studies (ILSs). The first ILS, dealing with the laboratory calibration of the tool, demonstrated performance robustness for 3 pesticides. The second in situ ILS demonstrated the relevance of the POCIS for sampling hormones, pharmaceuticals and pesticides from a waste water treatment plant effluent. This thesis permits to improve knowledge on the POCIS and to promote its application for the water framework directive

Full textAbstract:
Cette thèse avait pour objectif de mieux comprendre le phénomène de la dépendance à l’exercice en étudiant la relation de celle-ci avec des facteurs motivationnels et personnels variés. Différentes théories concernant la motivation, le perfectionnisme et l’estime de soi ont été utilisée afin de déterminer les facteurs les plus fortement liés avec la dépendance à l’exercice. Après le développement d’échelles de passion et de perfectionnisme adaptées à une population d’âges diverses, trois études empiriques ont été réalisées. La première étude a révélé quatre clusters distincts basés sur les profils motivationnels des individus. Le cluster incluant un grand nombre d’individus avec des scores très élevés pour la passion obsessive et le perfectionnisme socialement prescrit obtenait les scores les plus élevés pour la dépendance à l’exercice. La deuxième étude a démontrée, à l’aide des corrélations canoniques, une forte relation entre la passion obsessive et les différentes composantes de la dépendance à l’exercice. Finalement la troisième étude a démontré que la relation entre le perfectionnisme et la dépendance à l’exercice peut être médiée par la passion obsessive et par l’estime de soi dépendant du sport. La conclusion de cette thèse est alors que la passion obsessive est fortement liée à la dépendance à l'exercice, et que le perfectionnisme et une estime de soi fortement dépendant du sport jouent probablement un rôle important dans le développement de cette dépendance à l’exerciceThe objective of this thesis was to gain a better understanding of the concept of exercise dependence, by studying its relationship with a variety of motivational and personal factors. Different theories concerning motivation, perfectionism and self-esteem have been used in order to determine which of those factors were most strongly related to excercise dependence. After adapting the passion and perfectionism scales for use in populations of different ages, three empricial studies have been realized. The first study revealed four different clusters based on the motivational profiles of the individuals included. The cluster containing an important number of individuals with very high scores on obsessive passion and socially prescribed perfectionism obtained the highest scores for exercise dependence. The second study has shown, by using canonical correlations, a strong relationship between obsessive passion and the different composing factors of exercise dependence. Finally, the third study has revealed that the relationship between perfectionism and exercise dependence can be mediated by obsessive passion and by a self-esteem depending on sport. The conclusion of this thesis is therefore that obsessive passion is strongly related to exercise dependence, and that perfectionism and a form of self-esteem extremely dependant on sport, probably play an important role in the development of this exercise dependence

Full textAbstract:
Heat exposure causes several physiological and metabolic alterations. Although lipids are vital in sustaining energy production, heat-induced alterations in lipid metabolism have not been clearly established. CHAPTER 1 reviews the known metabolic alterations resulting from heat stress, with a specific focus on changes in whole-body lipid utilization and plasma lipids. CHAPTER 1also outlines the physiological changes caused by heat stress, and their role in reducing exercise performance. The study presented in CHAPTER 2 has shown that, compared to thermoneutral conditions, NEFA concentrations were 37% higher following passive heating and 34% higher following exercise in the heat, without significant changes in whole-body lipid utilization. In addition, the level of hyperthermia attained during passive pre-heating and exercise in the heat resulted in a 13% decrease in total external work and a significantly higher rate of perceived exertion. CHAPTER 3 summarizes the study results and presents the limitations and applications of the study.

Full textAbstract:
The effects of differing recovery patterns following intermittent exercise on blood lactate and subsequent performance were examined. Fourteen male subjects completed three randomly assigned experimental protocols. Each protocol consisted of eight 45s-bouts of cycling on a Monark cycle ergometer at 120% of VO$ sb2$ max interposed with five minute recovery periods. Each protocol ended with a maximal performance task consisting of a 45s all-out cycling test. Recovery patterns included passive, cycling (45% of VO$ sb2$ max), and arm cranking (45% of VO$ sb2$ max). Results revealed similar blood lactate concentrations in the passive and arm cranking conditions but significantly lower (p $<$.05) levels in the cycling condition. Mean power outputs measured from the performance task were significantly higher (p $<$.05) in the cycling and arm cranking recovery conditions. The correlation between blood lactate levels and mean power output was low (r = $-$0.28), suggesting that other factors were influencing subsequent performance.

Dunbar, Julia Lorene. "Passive Hallux Adduction Decreases Blood Flow to Plantar Fascia." BYU ScholarsArchive, 2018. https://scholarsarchive.byu.edu/etd/6928.
Full textAbstract:
Purpose: Due to the vital role that blood flow plays in maintaining tissue health, compromised blood flow can prevent effective tissue healing. An adducted hallux, as often seen inside a narrow shoe, may put passive tension on the abductor hallucis, consequently compressing the lateral plantar artery (LPA) into the calcaneus and thus restricting blood flow. The purpose of this study was to compare blood flow within the LPA before and after passive hallux adduction (PHA). Methods: Forty-five healthy volunteers (20 female, 25 male; age = 24.8 ± 6.8 yr; height = 1.7 ± 0.1 m; weight = 73.4 ± 13.5 kg) participated in this study. Blood velocity and vessel diameter measurements were obtained using ultrasound imaging (L8-18i transducer, GE Logiq S8). The LPA was imaged deep to abductor hallucis for 120 seconds: 60 seconds at rest followed by 60 seconds of PHA. Maximal PHA was performed by applying pressure to the medial side of the proximal phalanx of the hallux. Blood flow was then calculated in mL/min, and pre-PHA blood flow was compared to blood flow during PHA. Results: Log transformed data was used to run a paired t-test between the preadduction and postadduction blood flow. The volume of blood flow was 22.2% lower after PHA compared to before (–0.250 ± 0.063, p < 0.001). Conclusion: Although PHA is only a simulation of what would happen to the hallux inside of a narrow shoe, our preliminary findings of decreased blood flow through PHA suggest blood flow in narrow footwear and its effects on tissues within the foot are worth investigating.

Full textAbstract:
Introdução: Pacientes com DPOC apresentam prejuízo da função muscular respiratória relacionada aos sintomas respiratórios e aos fatores psicossociais bem como ao baixo condicionamento físico. O alongamento muscular respiratório surgiu como alternativa no tratamento da disfunção ventilatória nestes pacientes, entretanto ainda há carência de estudos que avaliem os benefícios da inclusão desta terapêutica ao exercício aeróbio. Objetivo: avaliar os efeitos da adição do alongamento da musculatura respiratória ao exercício aeróbico na mecânica toracoabdominal, capacidade funcional e aspectos psicossociais de pacientes com DPOC. Métodos: Este ensaio clínico envolveu 28 pacientes com DPOC moderada a grave aleatorizados em Grupo Tratado (GT; n=14) e Grupo Controle (GC; n=14). Todos os pacientes foram acompanhados duas vezes por semana, durante 12 semanas. GC realizou exercício aeróbico e GT teve adição do alongamento ao treinamento. Os volumes regionais pulmonares no tórax superior, tórax inferior e abdome e contribuição desses compartimentos no volume total (pletismografia optoeletrônica), a dispneia basal (MRC) e nas atividades de vida diária (LCADL), a qualidade de vida relacionada a saúde (CRQ), o controle clínico da doença (CCQ), os sintomas de ansiedade e depressão (HAD) e a capacidade funcional (teste de caminhada de seis minutos) foram avaliados de maneira cega. Resultados: Após o tratamento, no GT apresentou aumento do volume abdominal, redução da contribuição do tórax inferior no volume total, diminuição da dispneia após o teste de caminhada. GT e GC apresentaram melhores escores no MRC, no LCADL, no CCQ e na capacidade funcional. Não houve alteração da qualidade de vida e na pontuação do HAD. Conclusões: A adição do alongamento da musculatura respiratória ao exercício aeróbico é capaz de melhorar a mecânica toracoabdominal e a dispneia após o esforço em pacientes com DPOC. Nossos resultados também confirmaram os efeitos positivos do exercício aeróbio sobre a dispneia basal e durante realizações de atividades de vida diária, sobre o controle clínico da doença e sobre a capacidade funcional destes pacientesBackground: Patients with COPD have impairment on respiratory muscle function related to respiratory symptoms and psychosocial factors as well as low fitness. The respiratory muscle stretching could be an alternative for treatment of respiratory dysfunction in these patients; however, there are few evidence about the benefits of including this therapy to aerobic exercise. Objective: to assess the effects of adding stretching of respiratory muscles to aerobic exercise in thoracoabdominal mechanics, functional capacity and psychosocial factors in patients with COPD. Methods: This trial enrolled 28 patients with COPD moderate to severe randomized in Treatment Group (TG, n=14) and Control Group (CG, n=14). CG performed aerobic exercises and TC received adding respiratory muscles stretching twice weekly during 12 weeks. Blinded assessors evaluated regional lung volumes on superior thorax, inferior thorax and abdomen and their contribution on total chest wall volume (optoelectronic plethysmography), basal dyspnea (MRC), dyspnea during daily activities (LCADL), quality of life related with health (CRQ), clinical control of the disease (CCQ), anxiety and depression symptoms (HAD) and functional capacity (six minutes walking test). Results: After treatment, GT presented increase on abdominal volume and decrease on contribution of inferior thorax on total chest wall volume and lower dyspnea after walking test. Both groups presented improved scores on MRC, on LCADL, on CCQ and on functional capacity. Quality of life and HAD score was similar. Conclusions: Adding respiratory muscle stretching to aerobic exercise is able to improve thoracoabdominal mechanics and the dyspnea after effort in patients with COPD. Our results also confirmed the positive effects of aerobic exercise on dyspnea on baseline and during activity of daily living, on clinical control of the disease and on functional capacity of these patients

Full textAbstract:
Purpose The vascular endothelium is an influential contributor to vasodilation at rest, yet its role during peak exercise is relatively unknown. The purpose of this study is to determine if exercise leg blood flow during dynamic submaximal and maximal exercise is related to resting vascular endothelial function. Methods Nineteen subjects (aged 23 ± 0.57 yr) completed multiple assessments of vascular endothelial function including passive leg movement (PLM), rapid onset vasodilation, (ROV) and flow-mediated dilation (FMD). Peak muscle blood flow was assessed during single leg knee extension (KE) exercise. Doppler ultrasound of the femoral artery was utilized to assess muscle blood flow. Results Peak exercise blood flow was linearly related with microvascular endothelial function determined by PLM (P < 0.001) and ROV (P < 0.001). Normalizing muscle blood flow for quadriceps mass did not change this significant association. Individuals with high vascular endothelial function had greater muscle blood flow during KE compared to those with low endothelial function (P = 0.05). Post hoc analysis indicated a significant difference in blood flow between high and low endothelial function groups at 20 W, 30 W, and peak flow (P = 0.042, 0.048, 0.001, respectively). Conclusion Peak muscle blood flow during dynamic exercise is correlated with vascular endothelial function, as measured by PLM and ROV, accounting for between 30 to 50% of the variance in this relationship. These data support the hypothesis that endothelial function significantly contributes to the peak blood flow response during dynamic exercise.

Full textAbstract:
L’étirement passif occupe une place fondamentale dans l’examen clinique des complications motrices d’un Accident Vasculaire Cérébral (AVC) pour permettre d’identifier les structures musculo-tendineuses particulièrement touchées et servir, en complément d’autres mesures, à mettre en place la stratégie rééducative adaptée à chaque personne. Cependant, l’examen clinique évalue de façon globale les muscles d’un groupe musculaire sans identifier la contribution de chacun des muscles étirés. Ce projet de thèse visait à étudier la variabilité spatiale de la raideur à l’étirement passif des muscles fléchisseurs plantaires par la mesure du module d’élasticité (via la technique d’élastographie par ondes de cisaillement), et d’appliquer cette méthode auprès d’une population ayant été touchée par un AVC. Deux études ont été menées sur des sujets sains, puis sur un échantillon de patients présentant une hémiparésie post-AVC. Les résultats montrent que le module d’élasticité était plus important après l’AVC au niveau de régions bien précises au sein des muscles gastrocnemius medialis et soleus. Une dernière étude conduite auprès de participants sains a confirmé qu’un faible niveau d’activité musculaire (>1% du maximum) se répercutait de façon non négligeable sur les propriétés mécaniques des tissus durant l’étirement. Ces travaux apportent de nouvelles informations sur les localisations musculaires qui pourraient voir leurs propriétés mécaniques évoluer après l’AVC. Ils ouvrent vers de nouvelles perspectives de recherche visant à évaluer l’action de stratégies thérapeutiques individualisées selon la localisation des troubles observésStretching is used during clinical examinations in order to identify which structures (muscles) are affected by the motor consequences of a stroke injury. These results are important to promote a person-centered rehabilitation strategy. The classical approach to assess passive muscle properties consists of applying passive joint rotations, and to measure the torque developed in resistance to motion. However, this approach does not identify which muscle(s) contribute to the resistive torque. The aim of this thesis was to assess the effects of the stroke injury on the mechanical properties of lower leg muscles. Taking advantage of ultrasound shear wave elastography, the shear modulus of lower leg muscles was measured during passive ankle dorsiflexions on healthy participants to assess reliability of measurements. The protocol was then applied to stroke survivors. Results revealed that the increased levels of stiffness after the stroke injury were systematically found at the same muscle regions among plantar flexors: gastrocnemius medialis and soleus muscles. A last study showed that a small albeit of muscle activity (>1% of maximum) had non negligible effects on the joint torque measured during stretching. This series of studies provides novel insights into the mechanisms contributing to the increased muscle stiffness levels after a stroke injury among plantar flexors. It opens perspectives for future studies to determine the effects of individualized strategies applied to restore joint mobility regarding the most affected muscle regions

Full textAbstract:
Gymnasts must attain extreme ranges of flexibility to execute performance requirements, thus effective stretching proves vital to advancement in the sport. This study examined the acute effects of whole-body vibration (WBV) on passive and dynamic flexibility in young, female gymnasts. Participants (n = 27, Junior Olympic levels 5-10) served as their own control. Measurements of passive and dynamic flexibility were obtained using the TOPS forward split testing method to examine passive flexibility and dynamic flexibility was measured via split jumps that were analyzed with video and Dartfish software. According to randomized order, all participants completed a stretching protocol either with the WBV platform turned on (VIB) or off (C) separated by 48 h. Participants performed 4 sets of three stretches on the WBV platform. An ANCOVA was performed (using height, weight, age, years of experience, and gymnastics level as covariates). Significant improvements were found in passive flexibility for both VIB and C conditions, but there was no significant difference between the two stretching conditions (p = 0.17). The maximum split jump decreased significantly from pre to post measurement in both the VIB (p < 0.0001) and C (p = 0.04) conditions. VIB decreased the split jump significantly more than C. Based on the results of our study, an acute session of static stretching or stretching with WBV immediately before performance decreases split jump performance. Therefore, this WBV protocol is not recommended immediately prior to gymnastics competition.

Full textAbstract:
Spinal cord injury (SCI) is a devastating condition that not only results in motor and sensory loss, but also autonomic dysfunctions. Individuals with SCI experience a 3-4 fold increased risk of cardiovascular disease (CVD), the leading cause of mortality in this population. Endothelial dysfunction is among the earliest markers of CVD progression. This thesis aims to: 1) clarify previous reports showing a counterintuitive improvement in endothelial function after SCI, 2) examine the effect of autonomic dysreflexia (AD) on conduit vasculature, and 3) assess the efficacy of passive exercise (PE) to reverse vascular dysfunction. In uninjured controls (CON), T3-complete spinal cord transected Wistar rats (SCI), T3-transected with induced AD by colorectal distension (SCI+CRD), and T3-transected with PE (SCI+PE), we assessed endothelium-dependent vasodilation and specific mechanisms for relaxation in brachial (BA) and femoral artery (FA) using wire-myography. Sympathetic innervation, mechanotransducer expression [transient receptor potential channel V4 (TRPV4)], arterial morphology, and profibrotic markers were assessed using immunohistochemistry. Impaired reactivity to acetylcholine was seen in FA after SCI via decreased contribution of endothelium dependent hyperpolarizing factor (EDHF) mediated pathways, while BA showed preserved endothelial function. Moreover, FA in SCI exhibited inward remodelling, 37.7% less sympathetic nerve fiber density, and increased collagen I expression (53.0%). Chronic repetitive AD resulted in a shift in vasodilatory mechanisms away from nitric oxide and towards EDHF, hypersensitivity to phenylephrine, and reduced elastin expression (13.9%). Passive hind-limb exercise after SCI led to improved sensitivity of FA to acetylcholine, through an increase in TRPV4 and prostacyclin-mediated pathways for vasodilation. Outward remodelling, as well as decreased expression of transforming growth factor beta (47.7%) and collagen I (39.0%) was seen in FA after PE. We have shown, for the first time, the expected endothelial dysfunction in the inactive/supraspinally disrupted FA after SCI and that chronic repetitive AD resulted in exacerbation of vascular dysfunction caudal to injury. Furthermore, PE was effective in reversing endothelial dysfunction and provided atheroprotective benefit, indicating PE may be a viable therapeutic intervention for preventing CVD after SCI. The observed changes provide insight into the mechanisms of endothelial dysfunction and possible directions on improvement of vascular health after SCI.Medicine, Faculty of

The purpose of this study was to examine the effects of recovery modes and exercise durations on blood lactate concentrations and subsequent performance in cycling tests. Fourteen male subjects completed six randomly assigned experimental protocols with a combination of three durations and two modes of recovery (passive and active cycling at 45% VO$ sb{ rm 2 max}$). Each protocol consisted of eight bouts of cycling at 120% of VO$ sb{ rm 2 max}$ interspersed with five minute recovery periods. Each protocol terminated with a maximal performance task consisting of a 45s all-out cycling test. Results indicated significantly (p $<$ 0.05) higher blood lactate concentrations in the passive and 60s conditions. Mean power outputs measured in the performance task were significantly (p $<$ 0.05) higher in the active recovery conditions compared to passive recovery. Mean power outputs were lower during the 60s conditions. Since the correlation between blood lactate and mean power output was low (r = -0.24), other factors were influencing subsequent performance.

Full textAbstract:
Muscle weakness is the most common and persistent problem after a critical illness. Early mobilization of the critically ill patient, beginning with passive exercise and progressing to ambulation, may mitigate muscle effects of the critical illness. However, mobilization may produce adverse effects, especially early in the illness when risk for physiologic deterioration is common. If safe, introducing a mobility intervention early in the illness may facilitate ventilator weaning, shorten intensive care unit and hospitals stays, and improve functional status and quality of life for mechanically ventilated critically ill patients. The aim of this study was assess the cardiopulmonary and inflammatory responses to an early standardized passive exercise protocol (PEP) in mechanically ventilated critically ill patients. Using a quasi-experimental within-subjects repeated measures design, mechanically ventilated critically ill adults who were physiologically stable received a single standardized PEP within 72 hours of intubation. The PEP consisted of 20 minutes of bilateral passive leg movement delivered by continuous passive motion machines at a rate of 20 repetitions per minute, from 5-75 degrees, to simulate very slow walking. Physiologic parameters evaluated included heart rate (HR), mean blood pressure (MBP), oxygen saturation, and cytokine levels (IL-6 and IL-10), obtained before, during, and after the intervention. The Behavioral Pain Scale (BPS), administered before, during and after the intervention was used as a measure of participant comfort. The study sample was comprised of 18 (60%) males and 12 (40%) females, with a mean age of 56.5 years (SD 16.9 years), who were primarily Caucasian (N=18, 64%). Mean APACHE II scores for the sample were 23.8 (SD 6.2) with a mean predicted death rate of 48.8 (SD 19.8), indicating moderate mortality risk related to illness severity. Number of comorbidities ranged from 1-10 (X=4). All participants completed the intervention with no adverse events. Using repeated measures analysis of variance (rmANOVA), no significant differences were found in HR, MBP, or oxygen saturation at any of the four time points in comparison to baseline. BPS scores were significantly reduced (F(2.43, 70.42)=4.08, p=.02) at 5 and 10 minutes after the PEP was started, and were sustained at 20 minutes and for one hour after the PEP was completed. IL-6 was significantly reduced (F(1.60, 43.1)=4.351, p=.03) at the end of the intervention but not at the end of the final rest period. IL-10 values were not significantly different at any of the three time points, but IL-6 to IL-10 ratios did decrease significantly (F(1.61, 43.38)=3.42, p=.05) at the end of the PEP and again after a 60 minute rest period. Passive leg exercise was well tolerated by study participants. HR, MBP, and oxygen saturation were maintained within order set-specified ranges during and for one hour after activity, and patient comfort improved during and after the intervention. A downward trend in HR was noted in participants, which is contrary to usual HR response during exercise, and may represent clinical improvement in this population related to reduction in pain. Reduction of mean IL-6 values at the end of the PEP, but not after the rest period, suggests that the PEP was responsible for the initial IL-6 improvement. Improvement of IL-6 to IL-10 ratios from the end of the PEP to the end of the final rest period suggests that IL-10, although non-significant, may have had some effect, indicating that IL-10 increases may occur later than the time period of study. Passive exercise can be used as an approach to facilitating mobilization in mechanically ventilated critically ill adults until they are ready to participate in more active exercise. It could be that more frequent and aggressive exercise, such as passive cycling at faster rates, four times daily, will be tolerated in this population. While the understanding of clinical significance of cytokine profiles in critically ill patients is still evolving, cytokine levels may be useful in explaining benefits of mobilization in this population. Further study is required to replicate the impact of passive exercise on pain, and it may represent a novel approach to pain management in critically ill patients.ID: 031001499; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Adviser: .; Title from PDF title page (viewed July 26, 2013).; Thesis (Ph.D.)--University of Central Florida, 2012.; Includes bibliographical references.

Full textAbstract:
The purpose of this investigation was to determine the effect of passive and active recovery on the resynthesis of muscle glycogen after high intensity cycle ergometer exercise in untrained subjects. In a cross over design, six college-age males performed three, one min exercise bouts, at 130% V02max with a 4 min rest period between each work bout. Subjects refrained from exercise for two days prior to testing, and consumed a 15% carbohydrate solution (300g sugar in 2000ml of water) the day before each trial to help elevate glycogen concentration. The exercise protocol for each trial was identical, while the recovery following exercise was eitheractive (40-50% VO2max) or passive. The initial muscle glycogen values averaged 144.2 mmol•kg-1 w.w. for the active trial and 158.7 mmol•kg-1 w.w. for the passive trial. Corresponding post-exercise glycogen contents were 97.7 and 106.8 mmol•kg-1 w.w., respectively. These differences were not significant (P>0.05). However, the rate of muscle glycogen resynthesis during passive recovery increased 15 mmol•kg-1 w.w. whereas it decreased 6.27 mmol•kg-1 w.w. following active recovery (P<0.01). Also, the decrease in blood lactate concentration during active recovery was much faster than during passive recovery and significantly different at 10 and 30 min of the recovery period (P<0.01). The major finding of this investigation was that the rate of muscle glycogen resynthesis during passive recovery was significantly greater than that during active recovery. These data suggest that lactate can be used as an endogenous glycogenic precusor in muscle, and that glycogenesis was the prevalent pathway of lactate removal during passive recovery following high intensity cycle ergometer exercise.Human Performance Laboratory

Projeto de Graduação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Licenciada em FisioterapiaIntrodução: A avaliação da flexibilidade dos isquiotibiais (IT) é imprescindível pois um nível inapropriado de flexibilidade pode causar lesões nos tendões, músculos, e redução do desempenho atlético. Objetivo: Comparar os efeitos do alongamento passivo, com o fortalecimento excêntrico, na flexibilidade dos IT num grupo de jogadores de futebol veterano. Metodologia: Dezoito jogadores de futebol veterano do sexo masculino (idade 42 ± 5.2) foram divididos, aleatoriamente, em dois grupos: G.C e G.E. O teste usado para medição da flexibilidade dos IT foi o 90º/90º SLR, que avalia a amplitude articular no início do estudo e após 4 semanas, com o auxílio de um goniómetro. Foram avaliados os membros inferiores bilateralmente nos dois grupos. Resultados: Não existem diferenças significativas relativamente ao alongamento passivo e fortalecimento excêntrico no momento inicial e final de avaliação dos IT, em ambos os membros. Conclusão: Não há́ diferenças significativas entre os dois grupos para a flexibilidade dos IT, tanto no membro dominante, como no membro não dominante em futebolistas veteranos, no entanto, ambos produzem melhorias na flexibilidade dos IT, exceto no alongamento estático para o membro não dominante, num protocolo de 4 semanas.
Introduction: The performance of hamstrings flexibility is imperative since an inadequate level of flexibility can cause tendon and muscles injuries and low back pain, Objective: To compare the effects of a passive stretching with the eccentric strengthening on hamstring’s flexibility in a group of veteran soccer players. Methodology: Eighteen veteran male soccer players (age 42 ± 5.2) were randomly divided into two groups: C.G and E.G. The test used for measuring hamstring flexibility was the 90/90 SLR, evaluating the joint amplitude at the beginning of the study and after four weeks with the help of a goniometer and also evaluated the lower limbs bilaterally in both groups. Results: There were no significant differences in relatively to passive stretching and strengthening eccentric at the beginning and end of evaluation of the hamstring muscles, both in the dominant non-dominant limbs. Conclusion: There are no significant differences between the two groups for hamstring flexibility in both the dominant and non-dominant limbs in veteran soccer players; however, both produce improvements in hamstring flexibility except for static stretching for the non-dominant member, in a 4-week training protocol.

Full textAbstract:
The purpose of this study was to assess the acute effects of vibration and stretching on passive and active forward split range of motion in elite adult female synchronized swimmers. Eleven athletes performed a passive forward split test measuring the height of the anterior superior iliac spine on both sides and an active split test on both sides by adopting an inverted split position. Then athletes were assigned randomly by right or left leg to receive vibration on one leg while stretching. The contralateral leg was stretched but did not receive vibration and served as the control. The treatment involved a 40-s exposure to vibration of the forward leg in a split and 40 s of vibration to the rear leg in a split. The athletes were then post-tested using the same protocols. The results indicated that the vibration had a statistically significant influence on passive forward split flexibility, but not active split flexibility. The results of this study confirm earlier work and further demonstrate the efficacy of vibration in enhancing range of motion in a passive split position. Given that it is often difficult to achieve large changes in range of motion with already highly trained elite athletes, this methodology shows considerable promise. Vibration may not be powerful enough to evoke changes in active range of motion in spite of the changes in passive range of motion.

The purposes of this study were to evaluate the effects touches per play, post touches per play, and dribbles to end a play (DEP) have on points per play, field goal percentage, turnovers, and fouls. This was done to provide empirical evidence on anecdotal theories held by coaches concerning ball movement, dribbles, and post touches. The data collected were statistically analyzed using Bayesian hierarchical models. This study reports some intriguing trends. First, exceeding nine passes and three dribbles to end a play results in a decrease in points per play and field goal percentage. Second, up to three dribbles into a shot was more productive and efficient than shooting with no dribbles. Third, post play does not have as big an effect on offensive basketball as previously expected. Lastly, offensive rebounds seem to universally have a positive effect upon offensive basketball. This study supported some anecdotal beliefs about basketball, while not others, supporting the idea for statistically based studies to be conducted on anecdotal beliefs held about basketball.

Full textAbstract:
Introdução: os estudos sobre flexibilidade vêm tentando compreender quais propriedades explicam o aumento da amplitude de movimento (ADM), além do aumento de extensibilidade muscular. Propriedades mecânicas passivas de outros tipos de tecido, como o tendão, vêm sendo avaliadas, para entender a sua interferência no aumento da ADM. Desenho do estudo: o estudo foi do tipo ensaio clínico randomizado. Objetivos: analisar, minuto a minuto, o deslocamento da junção miotendínea (JMT) do músculo gastrocnêmio medial com o tendão do calcâneo e o torque passivo durante uma sessão de 10 minutos de alongamento estático passivo de flexores plantares, e analisar a mudança destas e de outras propriedades passivas mecânicas da unidade músculo-tendínea (UMT) do tríceps sural antes e após essa intervenção, verificando se estas mudanças perduram após 15, 30, 45 e 60 minutos após o protocolo de alongamento. Métodos: 30 participantes saudáveis foram divididos em grupo controle, o qual permaneceu em repouso, e experimental, o qual realizou uma sessão de 10 minutos de alongamento estático passivo no dinamômetro isocinético. Os participantes realizaram os testes de ADM, torque passivo, deslocamento da JMT e histerese antes e após a intervenção (0, 15, 30, 45 e 60 minutos). A partir dessas variáveis, foram calculadas as medidas de rigidez tendínea, muscular e da UMT. Resultados: Cinco participantes não permaneceram relaxados durante os testes e foram excluídos após análise dos dados eletromiográficos. 25 participantes foram incluídos na análise. Os resultados foram divididos em dois estudos diferentes. No primeiro estudo, apenas os 12 participantes do grupo experimental foram incluídos e, ao longo da intervenção, foi encontrada uma redução significativa do torque passivo, com a principal diferença ocorrendo nos minutos cinco e sete. No segundo estudo, foram comparados os indivíduos do grupo controle (n=13) e do grupo experimental (n=12), com um período de follow up de 60 minutos após a intervenção. A ADM aumentou e permaneceu aumentada até uma hora após a intervenção em ambos os grupos. As variáveis de deslocamento da JMT, rigidez muscular e histerese aumentaram em alguns momentos ao longo do tempo, sem diferença entre os grupos. A rigidez tendínea não apresentou diferença nem para grupo e nem para tempo. As variáveis de torque passivo e rigidez da UMT apresentaram uma interação significativa entre grupo e tempo, com uma redução das duas ao longo do tempo no grupo experimental. Conclusões: há uma redução de torque passivo ao longo de uma sessão de alongamento estático de 10 minutos dos flexores plantares de tornozelo, e fazer parte do grupo experimental influenciou no comportamento do torque passivo e da rigidez da UMT, levando a uma maior redução das mesmas para o grupo que realizou o alongamento. A ADM aumentou e permaneceu aumentada até uma hora após a intervenção.Background: studies on flexibility have attempted to understand which properties explain increased range of motion (ROM), in addition to increased muscle extensibility. Mechanical and passive properties of other types of tissue, such tendon tissue, have been evaluated in order to understand their interference in increased ROM. Study Design: randomized clinical trial. Objectives: to analyze, minute by minute, myotendinous junction (MTJ) displacement of the medial gastrocnemius muscle with Achilles tendon and passive torque during a 10-minute passive static stretching of the ankle plantar flexors. To analyze, also, the time course change of these and other muscle-tendon unit (MTU) mechanical properties of the triceps surae before and after the intervention, verifying if the changes persist after 15, 30, 45 and 60 minutes after the stretching protocol. Methods: 30 healthy participants were divided into a control group, which remained at rest, and an experimental group, which performed a 10-minute passive static stretching on the isokinetic dynamometer. Participants performed tests of ROM, passive torque, MTJ displacement and hysteresis before and after the intervention (0, 15, 30, 45 and 60 minutes). From these variables, the measures of tendinous, muscular and MTU stiffness were calculated. Results: Five participants did not remain relaxed during the test and were excluded after electromyographic data analysis. 25 participants were included in the analysis. Results were divided into two different studies. In the first one, only 12 participants of experimental group were included and during the intervention, a significant reduction of the passive torque was found, with the main difference occurring in minutes five and seven. In the second study, individuals from control group (n=13) and experimental group (n=12) were compared, with a 60 minute follow-up period after the intervention. ADM increased and remained increased up to one hour after the intervention. The variables of MTJ displacement, muscular stiffness and hysteresis increased at some moments over time, with no difference between the groups. The tendinous stiffness showed no difference neither for group nor for time. The variables of passive torque and MTU stiffness showed a significant interaction between group and time, with a reduction of the two over time in the experimental group. Conclusions: passive torque decreased throughout a 10-minute passive static stretching of the ankle plantar flexors, and being part of the experimental group influenced the behavior of the passive torque and the MTU stiffness, leading to a greater reduction of the same for the group who performed the stretching.

Full textAbstract:
Delayed Onset Muscle Soreness (DOMS) is a common response to activities involving lengthening contractions. Muscle inflammation is associated with DOMS and may play an integral role in protecting a muscle from damage and soreness in response to subsequent bouts of lengthening contractions. Research in animals has shown that prior exposure to passive stretching and isometric contractions of a muscle resulting in muscle inflammation attenuates the muscle inflammatory response following subsequent bouts of lengthening contractions. The purpose of this study was to determine whether passive stretching and isometric contractions in humans would reduce DOMS following a typical bout of resistance exercise. METHODS: Thirty untrained male subjects were assigned to a control (C), stretching (S) or isometric (I) contraction group (n=10/group). In the week prior to the typical resistance training bout subjects in S and I were exposed to 3 separate sessions involving 5 minutes of passive stretching or maximal isometric contractions, respectively. Passive and active soreness, thigh girth, and relaxed knee angle were assessed prior to intervention and on days 1, 2, 4, and 8 following the bout of resistance exercise. RESULTS: Passive and active muscle soreness increased similarly in all groups. However, active soreness returned higher values than passive soreness at several time points following resistance exercise. Peak soreness occurred at 48h post exercise. Thigh girth and relaxed knee angle reached their highest values at 5 minutes following resistance exercise however there were no differences between the groups. CONCLUSIONS: The present study demonstrates that a typical bout of resistance exercise is sufficient to cause measurable levels of DOMS in untrained subjects and that subjects are more sensitive to active measures of DOMS compared to a passive assessment. Nevertheless the passive stretching and isometric contraction interventions did nothing to reduce DOMS in the current subjects.

Full textAbstract:
[Truncated abstract] The inclusion of a warm-up in the form of prior exercise (PE) is generally advocated as a preparatory strategy of choice to improve sprint performance. Although there is evidence that both increasing muscle temperature and mobilising the cardiorespiratory system prior to exercise contribute largely to the benefit of PE on sprint performance, their relative importance is unknown. Another important question relates to situations where an athlete has to engage in a sprint shortly after one or several earlier sprints. Under these conditions, is engaging in mild exercise also the most effective preparatory strategy to adopt prior to sprinting when performed after a previous sprint(s)? It was the primary aim of this thesis to address these questions. Firstly, we hypothesised that there is a temporal shift in the mechanisms responsible for the effect of PE on power output during a maximal sprint effort, with temperature-dependent mechanisms playing a more important role at the onset of the sprint and mobilisation of the cardiorespiratory system playing a more important role later. To test this hypothesis, we compared the responses of a 30-s sprint to different PE protocols designed to control for either muscle temperature or pre-exercise VO2. ... A group of trained athletes was subjected to four consecutive bouts of 30-s sprint, each separated by 20 min of either active recovery at 40% VO2 peak or passive recovery. Our results show that PP, MP-20 and MP-10 did not fall between the first and last sprints, and were not affected by active recovery. In contrast, we found that MP10 and MP30 decrease significantly between the first and last sprint of the passive recovery trial, but not when active recovery is performed between consecutive sprints. Finally, this study also showed that the fall in mean power associated with repeated 30-s sprints in the passive recovery trial resulted primarily from a fall in early, but not late power output. These findings show that the early and late mean power output of repeated sprints respond differently to active and passive recovery, with the decrease in total mean power with repeated 30-s sprints resulting primarily from a fall in early as opposed to either late power output or peak power, thus highlighting the benefit of active recovery as a favourable preparatory strategy for the performance of repeated sprints of short (<10s) or longer duration (<30s), but not for repeated peak power.

Cette recherche menée au sein du pôle de recherche et développement de la société Perfect Memory s'intéresse à l'accompagnement de la mémoire familiale via un dispositif technique, interrogé par le prisme des sciences de l'information et de la communication. Elle propose la construction d'une approche d'éditorialisation du document numérique permettant à chacun de s'approprier son patrimoine culturel au travers de l'utilisation du dispositif technique co-construit, l'application Web Famille TM. L'interrogation du milieu socio-économique de la préservation et la valorisation du patrimoine culturel du particulier, auquel Perfect Memory appartient, nous amène à nous interroger sur les enjeux d'un rapprochement entre les notions de « numérique » et de « mémoire ». Un cadre théorique est ainsi construit, le document numérique est appréhendé comme support d'un exercice de la mémoire, permis par la médiation du dispositif technique. L'éditorialisation, en tant qu'ensemble d'opérations réalisées sur le document numérique par l'intermédiaire du dispositif technique, est placée au cœur de notre problématique axée sur les modalités d'accompagnement des pratiques mémorielles via le service Famille TM. La construction de notre approche d'éditorialisation est séparée en deux moments. Dans un premier temps, un corpus de documents numériques - productions familiales préservées par différentes institutions patrimoniales - est interrogé par une méthodologie sémiotique afin d'extraire les éléments saillants invariants à leur interprétation, que nous rassemblons sous l'appellation de marqueurs de mémoire. Dans un second temps, les catégories de marqueurs construits sont transcrites en recommandations éditoriales et ergonomiques destinées au dispositif technique Famille TM. Articulé jusqu'ici autour d'un axe unique - la documentarisation de l'archive -, le dispositif est enrichi de deux nouveaux modes - cinématographique et privé -, constituant autant de points d'entrée supplémentaires dans le document versé par l'utilisateur sur le service. L'approche d'éditorialisation du document est ainsi décomposée en trois modes, comportant chacun différents scénarii, articulation de fonctionnalités et d'une expérience utilisateur spécifiques, construits pour le service Famille TMThis research project was made at the R&D department at Perfect Memory and focus on how to support family memory via a technological artifact. We question the artifact through the prism of information and communication sciences. The project offers to build a new approach, that of the editorialization of digital documents, enabling each user to rediscover their cultural heritage. This can be done by means of Famille TM, a co-built Web app. Following a study of the cultural heritage market as applied to private individuals, to whom Perfect Memory belongs, we proceed to a cross analysis of two concepts : "Digital" and "Memory". Starting from these, we built a theoretical framework in which we consider digital documents as a base for memory training. The technological artifact allows such training through a mediation process. Editorialization, as a set of processes made on the digital document through a technological artifact, appears as central to our concern: to design ways to support memory habits through Famille TM. We divide the construction of an editorialization approach into two steps. First, we build a corpus of digital documents - home movies - from various cultural heritage organizations. Then we interrogate the corpus through a semiotic methodology in order to gather salient and invariant elements in each interpretation. We name them memory markers. In a second step, we transcribe the markers categorization into editorial and ergonomic recommendations for Famille TM. Until today, the technological artifact consisted in one single mode: the documentation of archives. We introduce two extra modes: the cinematographic experience and the private experience. Each mode provides the user with an original entry point into documents uploaded on the app. To summarize our editorialization approach, we implement three modes into Famille TM and for each of them we design several scenarios made up of specific features and user experiences

Introdução: O alongamento destaca-se como recurso empregado pelos fisioterapeutas no tratamento e prevenção de doenças musculoesqueléticas. Porém, a diversidade de técnicas, frequência, duração de sustentação do alongamento geram dúvidas do que é realmente necessário para se obter melhores resultados com o alongamento. Objetivo: Comparar dois tempos distintos de duração de alongamento em um programa de seis semanas de treinamento de alongamento estático passivo, 30s e 60s, sobre a flexibilidade e a força dos músculos isquiotibiais e força de quadríceps de mulheres jovens. Material e Métodos: Esta pesquisa se caracteriza por um estudo clínico randomizado de acompanhamento longitudinal. A amostra foi composta por 45 mulheres com idades entre 20 e 40 anos, divididas em três grupos (G30) programa de treinamento de alongamento estático passivo com 30 segundos de duração; (G60) programa de treinamento de alongamento estático passivo com 60 segundos de duração e (GC) grupo controle, sem intervenção. As coletas foram realizadas em três etapas, que consistiu em (1) pré-teste para avaliar a flexibilidade e força muscular de quadril e joelho, (2) a intervenção, onde foram executados alongamentos com diferentes tempos de execução, 30 e 60 segundos, realizados duas vezes por semana durante 6 semanas e (3) pós teste que consistiu na reavaliação da flexibilidade e força, após período de intervenção. Para obtenção dos valores de amplitude de movimento do quadril e do joelho foi utilizado um goniômetro universal e para a coleta de dados relativa à força muscular, o dinamômetro isocinético Cybex Norm. A análise estatística consistiu na aplicação do teste de Shapiro Wilk e Levene para ver a normalidade e homogeneidade dos dados, respectivamente. Para a comparação entre os grupos (G30, G60 e GC) e intragrupos em momentos distintos (pré e pós) foi utilizado uma ANOVA two way de medidas repetidas. Para avaliar as diferenças identificadas o post-hoc de Bonferroni foi utilizado. A análise foi feita no software SPSS 20.0 e o nível de significância adotado foi de 0,05. Resultados: Os resultados do presente estudo mostram um aumento significativo no pico de torque concêntrico de extensores do joelho do momento pré para o pós nos grupos de 30 segundos (G30) e 60 segundos (G60) e uma diminuição significativa para o controle (GC). O pico de torque excêntrico dos extensores do joelho também apresentou um aumento significativo do momento pré para o pós em todos os grupos. Porém não apresentou diferença significativa nos picos de torque concêntrico e excêntrico de flexores do joelho. Em relação à amplitude de movimento de quadril e joelho, não houve diferença significativa entre os grupos nem intragrupos nos diferentes momentos. Conclusão: Os resultados mostraram que um único alongamento, de 30s ou 60s, executado duas vezes por semana num período de treinamento de seis semanas é insuficiente para promover aumento na amplitude de movimento de quadril e joelho e de ganho de força do grupo muscular alongado (isquiotibiais). No entanto, parece influenciar no aumento da força do grupo muscular oposto ao alongado (quadríceps).Introduction: Stretching is a resource widely used by physiotherapists to treat and prevent musculoskeletal disorders. However, discrepancies in stretching techniques, training period, and duration of stretching make it complicated to ensure what stretching parameters lead to the most satisfactory results. Objective: to compare the effect of two distinct durations of stretching (30s and 60s) on hamstrings flexibility and strength of untrained young women during a six-weeks training program. Material e Methodos: This research is characterized as a randomized clinical longitudinal study. Forty-five women (20 to 40 years old) participated in this study, they were divided in three groups: passive static stretching held for 30 seconds (G30); passive static stretching held for 60 seconds (G60); and control group, no intervention (CG). Data collection was carried out in three phases: (1) pre-test of hamstrings’ flexibility and strength; (2) Intervention, in which either 30s or 60s of passive static stretching was performed twice a week for six weeks; (3) post-test of hamstrings’ flexibility and strength. Hip and knee range of motion was measured using a universal goniometer, whereas the information about knee force production was gathered using an Isokinetic Dynamometer. Regarding statistical analyses, Shapiro WilK and Levene tests were used to data normalization and homogenization, respectively. For inter-groups (G30, G60, and CG), and intra-groups (pre and post) comparisons a mixed ANOVA two way was performed. If significant interaction was observed, a Bonferroni post hoc test was conducted. All data were analyzed using SPSS 20, and statistical significance was set as p ≤ 0.05.Results: The results of the present study show significant increase of knee extensors Eccentric and Concentric Peak Torque in both G30 and G60 after stretching training, CG showed significant decrease on knee extensor Concentric Peak Torque, and increase on knee extensor Eccentric Peak Torque after stretching training. Nevertheless, knee flexors Concentric and Eccentric Peak Torque remained unaltered in all groups after stretching training. In relation to range of hip and knee movement, there was no significant difference between the groups or intra groups or the times. Conclusion: The findings showed that a single stretch , 30 or 60 s, of static stretching performed twice a week for six weeks are not sufficient to improve flexibility or strength of the stretched muscles. However, this parameter has an effect muscle strength of the antagonist group.

Full textAbstract:
É sugerido que sujeitos que apresentam uma musculatura mais rígida são mais suscetíveis ao dano muscular induzido pelo exercício (DMIE) do que aqueles indivíduos com musculatura mais complacente. Se através de um programa de treino de flexibilidade (TFlex) é possível tornar a musculatura mais complacente, é possível que um TFlex promova um efeito protetor sobre o DMIE? Desta forma, o objetivo do presente estudo foi avaliar o efeito de seis semanas de treino de flexibilidade dos isquiotibiais utilizando um alongamento estático, e se as alterações provenientes desse treino são capazes de alterar a resposta de DMIE. Métodos: Participaram do estudo 10 homens (idade 23,6 ± 3,9 anos, massa corporal 77,6 ± 12,5Kg, estatura 177,1 ± 6,8cm, gordura corporal 16,0 ± 8,2%), destreinados em força e flexibilidade. Como critério de inclusão, os sujeitos deveriam apresentar até 80° de ângulo de flexão de quadril em teste realizado de forma passiva. O estudo teve duração total de oito semanas, sendo que nas semanas inicial e final foram realizadas as avaliações pré e pós treinamento, e também na útima semana foram feitas as avaliações referentes ao DMIE. Na segunda semana iniciava o programa de TFlex com duração de seis semanas sendo duas sessões de treino por semana. Todos os indivíduos participaram do TFlex, sendo que um dos membros participou do treinamento (MT) e o outro membro não fez treinamento e serviu como controle (MC). Todas as sessões de TFlex foram realizadas no dinamômetro isocinético e o protocolo utilizado foi de oito séries de 60 segundos cada, sendo que a amplitude de movimento era mensurada em cada dia de treino. Antes de iniciar o programa de treino foram realizadas duas sessões de teste. Na primeira sessão foram realizadas as avaliações antropométricas, familiarização dos indivíduos com os procedimentos de coleta e foram realizadas as avaliações de espessura muscular, echo intensity, amplitude de movimento de flexão de quadril (ADMFlex), amplitude de extensão de joelho no dinamômetro isocinético (ADMExt), torque passivo máximo e relativo (TPMax e TPRelativo), contração isométrica voluntária máxima (CIVM) com simultânea aquisição de sinal eletromiográfico (EMG), pico de torque dinâmico (PT) e ângulo PT, e os mesmos testes foram reavaliados em uma nova sessão com pelo menos 48h de intervalo. Na semana imediatamente após o termino do TFlex, foram realizadas as avaliações pós- treino de flexibilidade, e, também nessa semana foi avaliado o efeito do DIME nos momentos pré, 0h, 24h, 48h e 72h após o exercício excêntrico. Resultados: O TFlex provocou aumento significante (p<0,05) de ADMFlex, ADMExt, e TPMax apenas no MT. Não foram observadas diferença (p>0,05) na CIVM, PT dinâmico, ângulo de PT, sinal EMG e espessura muscular em ambos os grupos do pré para o pós- treino. Após exercício excêntrico, foi observada significativa diminuição (p<0,05) de PT dinâmico, CIVM, ADMFlex e ADMExt, e significativo aumento (p<0,05) da dor e espessura muscular do bíceps femoral e do semitendíneo. Foi observada alteração da echo intensity 72h apenas no semitendíneo não houve alteração no sinal EMG. Não foi encontrada diferença significativa (p>0,05) entre MT e MC para as alterações provocadas pela DIME. Conclusões: o treino de flexibilidade provocou aumento de ADM e torque passivo máximo, o que sugere que o aumento da ADM tenha ocorrido por adaptações neurais. Porém o TFlex não foi capaz de conferir efeito protetor quanto ao DMIE.It is suggested that subjects with stiff muscle are more suscetible to exercise induced muscle damage (EIMD) than those with more complient muscle. If it is possible that the muscle become more complient through a flexibility training (FT), is it possible to have a protective effect on EIMD? Therefore, the aim of the present study was to evaluate the effect of six weeks of hamstring flexibility training using static stretching, and if the changes from the training are able to alter EIMD response. Methods: Ten untrained in strength and flexibility, men took part (age 23.6 ± 3.9 years, body mass 77.6 ± 12.5Kg, height 177.1 ± 6.8cm, body fat 16.0 ± 8.2%). As an inclusion criteria, the subjects should have until 80° of hip flexion on the passive straight-leg raise. The study lasted eight weeks, pre and post training evaluations took place in the first and in the last weeks, also in the last week EIMD evaluations were perfomend. In the second week, FT began with a total duration of six weeks with two training sessions per week. All subjects participated in the FT, wherein one limb took part of the training (TL) and the other limb participated as control (CON). All training sessions where performed in an isokinetic dynamometer and the protocol used was eigth sets of 60 seconds each, and the ROM was determined in each training session. Before initiate the training program, two testing sessions were performed. In the first session, anthropometric evaluation, familiarization with the data colection procedures, muscle thikness, echo intensity, hip flexion range of movement (ROMFlex), knee extension range of movement (ROMExt), maximum and relative passive torque (PTMax and PTRelative), maximal voluntary isometric contraction (MVIC) with simultaneous acquisition of electromyographic signal (EMG), dynamic peak torque (DPT) and peak torque angle were performed, and the same tests were reassessed in a new session with at least 48h interval. In the week immedately after the last FT session, post flexibility training were perfomed, and also in the final weeks was also evaluated the effects of EIMD, in pre, 0h, 24h, 48h and 72h post excentric exercise. Results: FT induced significant (p<0.05) increase in ROMFlex, ROMExt and PTMax only in the TL. It was not found difference (p>0.05) in PTRelative, MVIC, DPT, peak torque angle, EMG signal and muscle thikness in bouth groups from pre to post training. After excentric exercise, significant decrease (p<0.05) in DPT, MVIC, ROMFlex, ROMExt, significant (p<0.05) increase in pain, muscle thikness of the biceps femoris and of the semitendinous, for both groups. Sigfificant increase (p<0.05) in echo intensity for semitendineous after 72h were observed, and no significant (p>0.05) difference were found in the EMG signal. It was not found difference (p>0.05) in the alteration induced by EIMD between TL and CON. Conclusions: the flexibility training induced increase in ROM and PT, which suggests that these were neual adaptations. However, FT was not able to induce a protective effect on EIMD.

Žmogaus adaptacija prie karščio yra visapusiškai nagrinėjama ir plati problema (Hori, 1978). Literatūroje gausu tyrimų, nagrinėjančių hipertermijos poveikį neuroraumeninei funkcijai po fizinių pratimų karštyje (Nybo & Nielsen, 2001) ar pasyvaus šildymo (Thomas et al., 2006; Todd et al., 2005). M. M. Thomas et al. (2006) nustatė, kad pasyvaus šildymo metu, padidinus vidinę kūno temperatūrą iki 39,5 oC, sumažėja maksimali izometrinė pėdos lenkiamųjų raumenų jėga ir tai įtakoja raumenų aktyvacijos iš CNS sumažėjimas. Anksčiau atlikti tyrimai patvirtina, kad aukšta organizmo vidinė temperatūra paveikia CNS ir jos galimybę aktyvuoti dirbančius raumenis (Nybo & Nielsen, 2001; Todd et al., 2005). Organizmui aklimuojantis prie karščio, sumažėja TREKT, ŠSD, FSI ir padidėja prakaitavimas, kas lemia mažesnį fiziologinį-terminį stresą hipertermijos sąlygomis (Brazaitis ir kt., 2009; Brazaitis ir Skurvydas, 2010), tačiau sunku rasti tyrimų, nagrinėjančių kaip tai paveikia neuroraumeninę funkciją.

The literature is rich in research of analyzing the influence of hyperthermia on neuromuscular function, after exercising in the heat (Nybo & Nielsen, 2001) or passive heating (Thomas et al., 2006; Todd et al., 2005). M. M. Thomas et al. (2006) ascertained that the increase to 39,5 oC of core temperature in passive heating, reduces maximal isometric force of plantar flexors and this is influence of the reduction on voluntary muscle activation from CNS. Earlier studies show, that high core temperature affects CNS and its ability to activate working muscles (Nybo & Nielsen, 2001; Todd et al., 2005). Heat acclimation occurs with reduced rectal temperature, heart rate, physiological strain index and increased sweat rate, which causes reduction in physiological-thermal stress in the hyperthermia (Brazaitis ir kt., 2009; Brazaitis ir Skurvydas, 2010), but it is difficult to find studies how this affects the neuromuscular function. M. Brazaitis & A. Skurvydas (2010) found out that after 7 passive heating procedures (in ~44 oC water, 45 minutes each), which was carried out every second day for two weeks, heat acclimation occurred, but did not change the central and peripheral fatigue during a 2-min MVC in hyperthermia. In our study, we used the unique passive heating technique (we tried to elevate rectal temperature to 39,5 0C, maximal passive heating time was 120 min., 16 days of passive heating procedure...

Introdução: O alongamento é um recurso bastante presente em estratégias que visem à prevenção da flexibilidade e/ou reabilitação, e tem sido preconizado como sendo importante componente do exercício físico. Diversos estudos têm mostrado a eficácia de diferentes técnicas, porém não há unanimidade em estudos de efeito crônico no que diz respeito à técnica mais eficiente, bem como sua relação com a força muscular. Com isso o objetivo deste estudo foi comparar o efeito de duas formas distintas de alongamento sobre aspectos musculoesqueléticos dos isquiotibiais de mulheres jovens. Métodos: Este estudo é um ensaio clínico randomizado. A amostra foi composta por 18 mulheres jovens divididas em três grupos: (GCon) grupo controle (n= 6; 24,0±2,8 anos); (GEst) grupo que realizou alongamento estático passivo (n= 6; 23,3±2,2 anos) e (GFnp) grupo que realizou alongamento de facilitação neuromuscular proprioceptiva (n= 6; 24,6±2,6 anos). A avaliação do torque muscular, flexibilidade, ativação elétrica e arquitetura muscular foi realizada uma semana antes do início do treinamento e a reavaliação, uma semana após o término. Para a avaliação do torque muscular dos flexores e extensores do joelho foi utilizado um dinamômetro isocinético. A avaliação da flexibilidade foi composta pelos testes de Elevação do Membro Inferior Estendido (EXT) e de Extensão de Joelho Modificado (TEJ) onde a amplitude de movimento (ADM) foi mensurada através de um goniômetro universal. A avaliação da ativação elétrica do vasto lateral, reto femoral e bíceps femoral foi realizada simultaneamente ao teste de força muscular e flexibilidade utilizando-se um eletromiógrafo. A arquitetura muscular foi avaliada através da ultrassonografia. O treinamento consistiu de um programa de quatro semanas de alongamento com três sessões semanais. Cada sessão era composta por uma repetição de alongamento, estático (30s) ou FNP (6s de contração máxima seguido por 30s de alongamento). O GCon não realizou treinamento. Para análise estatística foi utilizada uma ANOVA de dois fatores para a comparação entre os grupos e entre momentos seguida de um posthoc de Bonferroni. Para análise foi utilizado o software SPSS 20.0 e o nível de significância adotado foi α de 0,05. Resultados: A ADM mensurada pelo teste EXT apresentou aumento significativo entre os momentos pré e pós do GEst (pré= 80,8º±11,0 e pós= 94,5º±10,2; p= 0,013), não havendo diferenças entre os grupos (p>0,05); também houve diferença no torque concêntrico dos flexores de joelhos nos três grupos quanto ao momento, GEst (pré= 66,3Nm±12,9 e pós= 70,0Nm±8,1; p=0,023), GFnp (pré= 79,1Nm±12,7 e pós= 83,5Nm±11,6; p=0,014) e Gcon (pré= 71,1Nm±10,1 e pós= 74,1Nm±14,6; p=0,003), porém não houve diferença entre os grupos. A contração excêntrica desse grupo muscular não apresentou diferença significativa intra e inter grupos, assim como a espessura e a ativação elétrica muscular (p>0,05). Conclusão: Não houve diferença entre os grupos, porém o protocolo de alongamento estático passivo proposto propiciou um aumento da ADM e do torque da musculatura isquiotibial, sem influência na espessura muscular e ativação elétrica, dados que sugerem ser o ganho de ADM decorrente do aumento da tolerância do indivíduo ao alongamento do que decorrente de mudanças na estrutura muscular.Introduction: Stretching is a very present action strategies aimed at prevention of flexibility and/or rehabilitation, and has been recommended as an important component of exercise. Several studies have shown the effectiveness of different techniques, but there is no unanimity in chronic effect studies as regards the most efficient technique, as well as its relationship with muscular strength. Thus the aim of this study was to compare the effect of two different forms of stretching on musculoskeletal aspects of the hamstrings of young women. Methods: This study is a randomized clinical trial. The sample consisted of 18 young women divided into three groups: (GCon) control group (n= 6; 24.0±2.8 years); (GEst) group performed passive static stretching (n= 6; 23.3±2.2 years) and (GFnp) group performed proprioceptive neuromuscular facilitation stretching (n= 6; 24.6±2.6 years). Evaluation of muscular torque, flexibility, muscle activation and muscle architecture was evaluated a week before the start of training and reevaluated, a week after the end. For the evaluation of knee flexors and extensors muscular torque was used an isokinetic dynamometer. The flexibility assessment was made by Single Leg Raise Test (SLR) and Modified Knee Extension Test (KET) where the range of motion (ROM) was measured using a goniometer. The evaluation of the electrical activation of the vastus lateralis, rectus femoris and biceps femoris was held simultaneously with the muscle strength test and flexibility using a electromyography. Muscle architecture was assessed by ultrasonography. The training consisted of a four weeks program of stretching with three weekly sessions. Each session consisted of a single stretching repetition, static (30s) or PNF (6s maximum contraction followed by 30 seconds elongation). The GCon not trained. Statistical analysis was performed using a two-way ANOVA for comparison between groups and between moments followed by post-hoc Bonferroni test. For analysis was used SPSS 20.0 and the level of significance was α of 0.05. Results: ROM measured by SLR test showed a significant increase between pre and post GEst (pre= 80.8º±11.0 and post= 94.5º±10.5; p= 0.013), with no differences between the groups (p> 0.05); also was difference between pre and post training in concentric torque of the knee flexors in the three groups, GEst (pre= 66.3Nm±12.9 and post= 70.0Nm±8.1; p= 0.023), GFnp (pre= 79.1Nm±12.7 and post= 83.5Nm±11.6; p= 0.014) and GCon (pre= 71.1Nm±10.1 and post= 74.1Nm±14.6; p= 0.003), but there was no difference between groups. The eccentric contraction of this muscle group showed no significant difference intra and inter groups, as well as the thickness and muscle electrical activation (p>0.05). Conclusion: There was no difference between the groups but the proposed passive static stretching protocol provided an increase in ROM and torque of the hamstring muscles, but no effects on muscle thickness and electrical activation, data that suggest the gain of ROM occurred due to the increase of the individual's tolerance to stretching, and not from changes in muscle structure.

However not many research projects analyzing the impact of the acclimation (In vitro(in laboratory) related long term acclimatization) to hyperthermic environment, created in imitative way, neither on the fluctuation of man’s vital functions nor on the maximum voluntary muscle strength, could be found. Secondly, it should be noted, that none of the above mentioned sources provided the information on the change of muscle electric activity at the moment of its maximum voluntary strength. Therefore, the main purpose of this research was to establish and measure the influence of the imitative acclimation of hyperthermia on the man’s body. The main tasks of the project were to observe and evaluate the change of man’s physiological functions (rectal, skin and body temperature, physiologic stress, weight loss, heart rate and thermic stress) during the acclimation to hyperthermia process: before passive heating, during the heating time and after it; to establish the impact of acclimation to hyperthermia on the maximum voluntary force as well as on the maximum activation rate; to establish and measure the impact of the acclimation to hyperthermia on the muscle electrical activity.

Full textAbstract:
In his most popular prose work, Mary Magdalens Funeral Teares (1591), English Jesuit Robert Southwell adapts the Mary Magdalene tradition by incorporating the meditative practices of St. Ignatius Loyola coupled with the Petrarchan language of poetry. Thus, he creates a prose work that ministered to Catholic souls, appealed to Protestant audiences, and initiated the literature of tears in England. Southwell readapts the traditional image of Mary Magdalene for a Catholic Early Modern audience by utilizing the techniques of Jesuit meditation, which later flourished in the weeper texts of Richard Crashaw and George Herbert. His vividly imagined scenes also employ the Petrarchan and Ovidian language of longing and absence and coincide with both traditional and mystic early church writers such as Bernard and Augustine. Through this combination, Southwell’s Marie Magdalens Funeral Teares resonated with Catholics deprived of both ministry and the presence of Christ in the Eucharist. These contributions solidify Southwell’s place as a pivotal figure in the religious and literary contexts of Early Modern England.

Abstract The purpose of this study was to understand the association between the exercise passion and exercise dependence in the middle and old age exercisers and explore the difference between exercise passion and exercise dependence at various background variables (age, and exercise history). The number of the participants in this study, the exercisers from several sports grounds and parks in Taipei City, was 300, including 162 males and 138 females. Their average age was 47.5. The background information, exercise passion measurement and exercise independence measurement were applied as the study tools. The data were treated using statistic analyses, such as product-moment correlation, canonical correlation, one-way ANOVA, and independent samples t-test. As to exercise passion, the results showed that obsessive passion and harmonious passion correlated positively with the various dimensions of exercise dependence. The analysis results of canonical correlation correlated through the first group of canonical correlation principally. The continuance of exercise dependence was much more when the amount of obsessive passion was higher. The exercise passion and exercise dependence of the exercisers did not differ along with age. As to exercise dependence, withdrawal, lack of control, time, intention effect, and reduction in other activities differed at “exercise history” significantly. Withdrawal, lack of control, time, and reduction in other activities in the exercisers with an exercise history of over eleven years were higher than those in the exercisers with an exercise history of 1~5 years. Lack of control, time, and reduction in other activities in the exercisers with an exercise history of 6~10 years were higher than those in the exercisers with an exercise history of 1~5 years. At last, discussions and recommendations were submitted pertaining to the results.

Background: Warm-up before exercise could increase blood flow of whole body, increase muscles and skin temperature, prevent injury within exercise. Passive warm-up can increase temperature of muscles and skin as active warm-up do, but it won’t cause the activity of the muscles. Purpose: To determine the effects of two different modalities of passive warm-up and exercise without warm-up on exercise performance and recovery on muscle damage. Methods: Eight volunteers were participated in this study (age =23.88±5.06 y/o), and all of them were involved into three groups as control group (CON), heat packing group (HP) and ultrasound group (USD). CON never received any warm-up protocol before eccentric exercise, HP received 15 minutes of superficial heat with electrical heat pack before exercise, and USD received 7 minutes of deep heat with ultrasound diathermy before exercise. Each subject processed 30 repeated bouts of eccentric exercise with 80% MVC level. Serum CK, MVC, ROM and CIR were measured before, immediately after exercise and at 2nd, 4th, 7th, and 10th days post-exercise. Results: When measuring serum CK and CIR, there were no significant difference between CON, HP and USD (p>0. 05). When measuring ROM and MVC, there were significant difference between CON, HP and USD (p<0. 05). Conclusion: USD and HP have better muscle strength and performance than CON. According to the recovery procedure, USD took lesser damage on muscles than HP and CON. USD had lesser swelling then HP and CON in recovery stage after exercise.

Purpose: To examine the relationships between exercise passion, perceived leisure risk, and leisure benefits in scuba diving participants. Method: Two hundred scuba divers (age ranged from 20 to 60 years) were recruited to complete a battery of questionnaires regarding exercise passion, perceived leisure risk, and leisure benefits in a resting setting. Data obtained in this study were analyzed by correlated analyses and multiple regression analyses. Results: Compared with the diving beginners, those who were certified divers indicated higher perceptions of diving risk and diving benefits. For the certified divers, harmonious and obsessive passion and perceived leisure risk could positively predict leisure benefits. For the beginners, harmonious passion and perceived leisure risk were positively associated with leisure benefits, whereas obsessive passion was negatively related to leisure benefits. Conclusion: The findings indicate that individuals may perceive larger benefits in physiological, psychological, and social aspects when they gain greater knowledge of diving risk. Diving experience seems to be a moderator between exercise passion and leisure benefits. Those beginners tend to develop an inflexible style of passion toward diving that would hinder leisure values. Therefore, diving club managers should notice this important issue.

The purpose of this study was to investigate the differences of exercise dependence, commitment and passion among marathon, half- marathon and 10K runners; and to see the different passion and commitment among exercise dependent groups. The relationships between exercise dependence, commitment and passion were also tested. Participants were 132 female and 239 male who completed Exercise Dependence Scale-Revised, Exercise Commitment Scale and Exercise Passion Scale after a marathon competition near Cha-Yi and Yun-Lin County. Analyses were conducted using one-way MANOVA and Canonical analysis. Results revealed that marathon runners had higher exercise dependence, passion and commitment than half-marathon and 10K runners. At risk for exercise dependence group also had higher exercise commitment and passion than not at risk for exercise dependence groups. Runners who had higher exercise commitment and passion possessed higher exercise dependence symptoms. Runners’ obsessive passion was correlated to want to commitment of exercise. Excessive exercise or over training is easy to link to exercise dependence of marathon runners who also with higher exercise commitment and passion. Consultant and assistance are needed for runners who emerged dependent symptom in their daily life. The differences of exercise dependence between elite runners and leisure runners for future research are needed.

Purpose: This study was to examine the relationships among social support, exercise passion, and well-being perception of table tennis participants with different demographic variables. Method: The questionnaire survey was completed by 217 amateur table tennis players in Taipei area. In addition to demographic information, three scales regarding social support, exercise passion, and well-being perception were administered. The date collected were analyzed by using one-way ANOVA and stepwise multiple regression analysis. Results: Family support of the elderly and the young groups was higher than that of the mid-aged group. Those who exercise more than 6 hours weekly perceived higher sense of family support, friend support, team support, and well-being. Further, those who have been playing for more than 6 years experienced higher sense of friend support, team support, harmonious passion, and well-being. Team support and harmonious passion could positively predict the sense of well-being. Conclusion: For amateur table tennis players, the mutual support from their teammates and harmonious passion can enhance life satisfaction. The findings will be used as a helpful reference by different associations when arranging relative trainings or programs.

This thesis encompasses two studies which main purpose lies in using parents’ passion in exercise to test the process that parents influence children’s beliefs and behaviors in exercise participation through the mechanism of parent as role model. Study 1 revises an instrument suitable for testing exercise passion of elementary school childrens’ parents. Study 2 examines the differences among the expectancy belief, value belief, and exercise behavior of children whose parent have different pattern of exercise passion. Study 1 modified the passion scale (Li, et al., 2007). With 365 adults (M=35.94 yrs) participated, the result of item analysis and CFA showed the scale have acceptable factor structure, reliability, convergent validity, and discriminate validity. 540 families particiapted in study 2. The result of MANOVA showed father’s passion pattern didn’t influence childrens’ expectancy belief, value belief, and exercise behavior. However, the children, whose mother have high harmonious passion and low obsessive passion, had higher expectancy belief and value belief than children whose mother have low harmonious passion and high obsessive passion.

Purpose: To examine the predictive effect of exercise passion and perceived leisure benefits on psychological well-being in slow-pitch softball participants. Method: Two hundred male players (mean age 35.21 years) were recruited to complete a battery of questionnaires in a group setting to measure exercise passion, perceived leisure benefits, and psychological well-being. Data obtained in this study were analyzed by correlated analyses and multiple regression analyses. Results: Exercise passion, either harmonious or obsessive passion, could positively predict life satisfaction. More, obsessive passion and social leisure benefit could positively predict positive affect. Conclusion: The findings suggest that exercise passion seems to be beneficial to life satisfaction of exercise participants, regardless of passion type. Additionally, higher perception of social leisure benefit is helpful to the enhancement of general positive affect of exercise participants. The findings help practitioners further understanding the factors influencing subjective well-being of leisure exercise participants and develop strategies to promote slow-pitch softball.

There is a lack of consensus on whether heart rate recovery (HRR) post-peak exercise follows a sexually dimorphic pattern. We hypothesized that two groups of men and women paired-matched for age and level of cardiorespiratory fitness (peak oxygen uptake - VO2peak percentile) would exhibit similar HRR from peak exercise intensities.
Methods: Forty healthy individuals (23 men and 17 women), aged 18 to 28 years, with above average cardiovascular fitness (VO2peak > 50th percentile), performed a peak cycle-ergometer tests with cardiorpulmonary measurements. HRR was obtained at the 1st (HRR1min) and 2nd min (HRR2min) of passive recovery. Student t tests were computed to explore possible differences between men and women for anthropometric and cardiopulmonary data obtained at rest, during exercise and recovery. Multiple linear regression analysis was used to determine whether the relationship between VO2peak and HRR differed between sexes. We used HRR1min and HRR2min as dependent variables and VO2peak, sex and the interaction between sex and VO2peak as independent variables.
Results: There were no between-group differences for the VO2peak percentile, RER or peak heart rate (p > 0.05). In contrast, men attained higher peak values for VO2 and work rate (p < 0.05). Both sexes had similar HRR post-peak exercise (p > 0.05). In multiple linear models, VO2peak explained 11.2% of HRR1min variance. As importantly, sex, VO2peak and their interaction were all significant predictors of HRR2min (explained variance: 29.2%) (p < 0.05). When the differences between sexes in VO2peak were controlled for, HRR remained similar between sexes both at 1 and 2 min of recovery.
Conclusion: This study shows that, for a given VO2peak percentile (VO2peak percentile > 50th percentile), HRR is similar between men and women. For this reason, we conclude vagal reactivation post-peak exercise does not follow a sexually dimorphic pattern.Objetivos: O atraso na recuperação da frequência cardíaca (RFC) após o esforço associa-se a uma pobre reativação vagal e representa um marcador prognóstico de patologia cardiovascular. Atualmente, não existe consenso sobre se a RFC pós-exercício de pico segue um padrão de dimorfismo sexual. Colocou-se a hipótese de que dois grupos de homens e mulheres, emparelhados por idade e nível de aptidão cardiorrespiratória (percentil de VO2pico), apresentariam valores semelhantes de RFC. Métodos: 40 participantes saudáveis (23 homens e 17 mulheres), com idades entre 18 e 28 anos, com aptidão cardiovascular acima da média (VO2pico > percentil 50), realizaram uma prova de esforço de pico em ciclo-ergómetro com medidas cardiorrespiratórias. A RFC foi obtida ao 1º e 2º minuto de recuperação passiva. Recorreu-se ao teste t Student para explorar possíveis diferenças entre homens e mulheres para dados antropométricos e cardiorrespiratórios obtidos em repouso, durante e depois do exercício de pico. Procedeu-se ainda à análise da regressão linear múltipla para determinar eventuais diferenças sexuais na relação entre VO2pico e a RFC. Definiram-se como variáveis dependentes a RFC ao primeiro e segundo minuto (RFC1min e RFC2min, respetivamente). Já o VO2pico, o sexo e a interação entre sexo e VO2pico foram definidos como variáveis independentes. Resultados: Não houve diferenças entre os dois grupos para o percentil de VO2pico, quociente de trocas respiratórias de pico ou pico de frequência cardíaca (p> 0.05). No entanto, os homens obtiveram valores superiores do que as mulheres para o pico de VO2 e taxa de trabalho (p < 0.05). Ambos os sexos tiveram uma RFC semelhante após o esforço de pico (p > 0.05). Nos modelos lineares múltiplos, o VO2pico explicou 11.2% da variância da RFC. Já no que se refere à RFC2min, verificou-se que um modelo composto pelas variáveis sexo, VO2pico, e sua interação alcançou um poder explicativo equivalente a 29.2% da variância da RFC (p < 0.05). Quando as diferenças entre os sexos foram controladas com recurso à análise de covariância, a RFC subsistiu como semelhante entre sexos quer ao 1º como 2º min de recuperação. Conclusão: Este estudo demonstra que, para um dado percentil de VO2pico (> percentil 50), não há dimorfismo sexual na frequência cardíaca de recuperação obtido ao 1º e 2º minuto de recuperação. Por este motivo, conclui-se que o perfil de reativação vagal pós-esforço de pico não se rege por um padrão de dimorfismo sexual.

In recent years, many researchers have studied how to employ power assisting devices in order to improve the efficiency of exercise and rehabilitation. There are some criteria when designing power assisting devices: 1). Power assisting devices should assist users in accomplishing movements designed for exercise or rehabilitation in the training of specific muscles; 2). Power assisting devices should provide moderate loads for users to enhance the effectiveness of exercise and rehabilitation. 3). Power assisting devices should ensure the safety of users. In this thesis, a control scheme is proposed for arm exercise and rehabilitation devices. In order to assist users in accomplishing the desired movements, the computed torque method is applied to achieve trajectory tracking for the devices, while a disturbance observer is proposed to compensate for disturbance, so as to improve the tracking performance. In order to provide moderate loads for the users, impedance control is employed to adjust the dynamics of the devices to act as mass-spring-damper systems. Instead of employing the force sensor, the disturbance observer is utilized to estimate the contact force of users so as to overcome the disadvantages of the force sensor, such as narrow bandwidth and high cost. In order to ensure the safety of users, passive velocity control is employed to maintain the passivity of the system. Lastly, an experimental platform is constructed to verify the control scheme proposed in this thesis.

It is known that exercise has beneficial effects on brain functions, including neural plasticity and learning and memory, and that amygdala and serotonin (5-HT) system play critical roles in regulating fear memory. However, whether exercise-enhanced fear memory is regulated at least in part by serotonin system is still unknown. Therefore, we examined step-through passive avoidance, and levels of 5-HT and its metabolite (5-HIAA), protein expression of 5-HT1A, 5-HT2A receptors and 5-HT transporter in related brain regions, including prefrontal cortex, hippocampus, and amygdala, after 4-wk compulsive treadmill running in male Sprague-Dawley rats. The role of serotonergic system in exercise-enhanced avoidance task was further investigated by pharmacological approaches. Our results demonstrated that (1) treadmill exercise training enhanced passive avoidance learning performance 24h after passive avoidance training; (2) exercise decreased 5-HT1A and 5-HT2A receptors protein expression, determined by Western blotting, in the right amygdala, but not in the prefrontal cortex and hippocampus. In addition, the expression of 5-HT transporter protein remained unaltered after exercise; (3) treadmill exercise decreased 5-HT levels, measured by HPLC, in the hippocampus; (4) pretreatment of the selective 5-HT1A receptor agonist (8-OH-DPAT) and the 5-HT releasing compound (PCA) impaired passive avoidance performance, but only the administration of 8-OH-DPAT abolish exercise-enhanced fear memory. In addition, the pretreatment of 5-HT drugs did not produce a significant change in pain sensitivity, assessed by hot-plate test. The results suggest that down-regulation of 5-HT1A receptor may be involved in exercise-enhanced fear memory. Whether the reduction of 5-HT1A and 5-HT2A receptors expression in amygdala is involved in the beneficial effects of physical activity on fear memory will be further clarified.
