Payne, Rupert Alistair. "Pulse transit time and the pulse wave contour as measured by photoplethysmography : the effect of drugs and exercise." Thesis, University of Edinburgh, 2009. http://hdl.handle.net/1842/5950.
Full textAbstract:
Photoplethysmography (PPG) is a simple means of measuring the pulse wave in humans, exploitable for the purposes of timing the arrival of the pulse at a particular point in the arterial tree, and for pulse contour analysis. This thesis describes a methodology for measuring arterial pulse transit time (PTT) from cardiac ejection to pulse arrival at the finger. It describes the effect on PTT of drug and exercise induced changes in BP. The nature of the relationship between the PPG and arterial pressure is also examined, and the PTT technique extended to assessment of conduit vessel pulse wave velocity (PWV) during exercise. PTT measured from ECG R-wave to PPG finger wave (rPTT) had a negative correlation (R2=0.39) with systolic BP (SBP), unaffected by vasoactive drugs in some but not all persons. rPTT showed similar beat-to-beat variability to SBP, unaffected by drugs. rPTT correlated weakly with diastolic (DBP) and mean (MAP) pressure. Cardiac pre-ejection period (PEP) formed a substantial and variable part of rPTT (12% to 35%). Transit time adjusted for PEP (pPTT) correlated better with DBP (R2=0.41) and MAP (R2=0.45), than with SBP. The PPG wave tracked changes in the peripheral pressure wave. Drugs had little effect on the generalised transfer function (GTF) describing the association between arterial and PPG waves. Strenuous exercise induced a large decrease in rPTT, mainly accounted for by decreases in PEP (53% of the total change in rPTT) and in transit time from aorta to distal brachial artery (33%). In contrast, minimal change in transit time from wrist to finger tip occurred with exercise. Simultaneous ear-finger PPG signals were used to measure conduit artery PWV during exercise. Ear-finger PWV (PWVef) overestimated carotid-radial PWV throughout exertion (overall bias 0.81±1.05ms-1, p<0.001), but the degree of difference remained constant. The increase in PWVef with exercise, was greater (1.18±0.54ms-1, p=0.035) in healthy subjects with a positive cardiovascular family history compared to those without. PPG enables analysis of the pulse contour during exercise, but estimation of the radial pressure wave from finger PPG by use of a GTF derived at rest, resulted in inaccuracy following exertion. These effects were variable and relatively short-lived. Furthermore, a resting GTF used to determine central pressure from the peripheral wave, resulted in underestimation of SBP (-5.9±2.1mmHg) and central pressure augmentation index (-8.3±2.9%), which persisted for 10 minutes post-exercise. rPTT had a negative linear association with SBP (R2=0.94) during strenuous exercise, slightly stronger than during recovery (R2=0.85). Differences existed in area-undercurve of the rPTT/SBP relationship between exercise and recovery, due to discrepancies in rate and degree of recovery of SBP and PEP. The linear relationship between the rPTT/SBP during exercise was affected by aerobic capacity, and the regression slope was less in the anaerobic compared to aerobic phase of exercise due to minimal change in PEP during anaerobic exertion. The correlation between rPTT/SBP did not change with prolonged aerobic exercise. Finally, measures of baroreflex sensitivity during exercise, were not significantly different between actual beat-to-beat SBP and SBP estimated using rPTT. In conclusion, absolute BP cannot be reliably estimated by measurement of rPTT following administration of drugs and during exercise. However, rPTT may have a role in measuring BP variability and in the assessing exercise capacity. PPG may also be useful in determining the effects of exercise on arterial stiffness, and for estimating the pressure wave contour, although its use during exercise for the latter purpose must be treated with caution.

"Peristaltic Pulse Dynamic Compression of the Lower Extremity Enhances Flexibility." Digital Commons @ East Tennessee State University, 2014. https://dc.etsu.edu/etsu-works/4621.
Full textAbstract:
This study investigated the effects of peristaltic pulse dynamic compression (PPDC) on range-of-motion (ROM) changes in forward splits. Serious stretching usually involves discomfort and large time investments. Tissue structural changes and stretch tolerance have heretofore been considered the primary mechanisms of enhanced ROM. The PPDC treatment was computer controlled. Circumferential and segmented inflation pressures were induced by feet to hip leggings. Nine subjects, experienced in stretching and a forward split position, volunteered. The subjects were familiarized with the protocol and randomly assigned to an initial condition: experimental (PPDC), or control (CONT). The study involved a crossover design. Second conditions were tested within 1–5 days. All tests were 2 trials of right and left forward splits. Split flexibility was assessed by measuring the height of the anterior superior iliac spine of the rear leg from the floor. Pelvic posture was controlled by rear leg position. The PPDC treatment was 15 minutes of seated PPDC. The control condition was the same except that leggings were not inflated. Pressures of 5 cells in the leggings were set at factory defaults, 70 mm Hg sequentially. Difference score results indicated statistically significant (p ≤ 0.05) differences by condition and the condition by leg interaction. The rapid acute changes in ROM (PPDC: right 25.3%, left 33.3%; CONT: right 12.2%, left 1.0%) support the premise that changes in ROM were dependent on mechanisms other than tissue structural changes and/or stretch tolerance. PPDC provides a means of rapidly enhancing acute ROM requiring less discomfort and time.

Full textAbstract:
To assess the relationships of body mass index (BMI) on arterial stiffness at rest and post-maximal treadmill graded exercise testing (GXT).
Forty-four apparently healthy, young adult males (22.1 ± 0.48 years) were recruited and divided into either a healthy weight (H, ≤24.9 kg/m2), overweight (OV, 24.9-29.9 kg/m2) or obese (OB, ≥29.9 kg/m2) group based on BMI. All subjects underwent arterial stiffness (carotid-femoral pulse wave velocity, cfPWV), blood pressure (BP), pulse pressure (PP), mean arterial pressure (MAP) and body composition (bioelectrical impedance analysis, BIA) measurements at rest. Following the GXT, measures of arterial stiffness (cfPWV) and BP were acquired.
Resting measures of cfPWV, BMI, systolic BP, diastolic BP, MAP, and PP were significantly (p <0.05) greater in OV and OB compared with H. Compared with OV, OB had a greater BMI. Relative peak oxygen consumption (VP2peak) was greater in H compared with OV and OB (p<0.05). systolic BP was positively associated, whereas VO2peak was inversely related to cfPWV (p<0.05). No significant inter-group interactions were observed with cfPWV after the GXT. However, interactions were observed for SBP, DBP and PP (p<0.05).
In young men with varying BMI, SBP and VO2peak were associated with resting cfPWV. However, similar cardiovascular responses were observed between groups after a maximal GXT.

Full textAbstract:
The prevalence of obesity and type II diabetes is increasing. Although exercise is widely accepted for prevention and treatment, evidence of resistance to exercise in patients with these diseases is also mounting. Muscle contraction during exercise stimulate cellular responses important for adaptation. These responses include the release of myokines and the subsequent increase in substrate metabolism. This study aimed to define a culture model for simulating exercise in human primary skeletal muscle cells. We hypothesized that chronic electric pulse stimulation (EPS) of human myotubes in vitro would emulate cellular and molecular responses to exercise observed in vivo. To define this model, we applied EPS to human myotubes for varied lengths of time and measured interleukin-6 (Il-6), peroxisome proliferator-activated receptor gamma coactivator 1- (PGC1-), superoxide dismutase 2 (SOD2), substrate metabolism, metabolic enzyme activity, heat stress markers, and pH. To recreate the inflammatory milieu observed in metabolic disease states we treated the myotubes with a low dose of 20 EU lipopolysaccharide (LPS). Following the 24-hour stimulation we observed significant increases in transcription of Il-6, PGC1-, and SOD2. Basal glucose and fatty acid oxidation were also markedly increased in the cells after EPS. Cells treated with LPS elicited a blunted transcriptional, metabolic, and enzymatic response to EPS. These findings suggest that EPS is a viable model for simulating the effects of exercise. Our observations also indicate that an inflammatory environment could play a role in interfering with the adaptations to exercise.Ph. D.

Full textAbstract:
The purpose of this study was to explore the efficacy of two existing pulse contour analysis (PCA) models for estimating cardiac stroke volume from the arterial pressure waveform during kicking ergometer exercise and head-up tilt manoeuvres. Secondly, one of the existing models was modified in an attempt to enhance its performance. In part I, seven healthy young adults repeated two submaximal exercise sessions on a kicking ergometer, each with three different sets of steady-state cardiac output comparisons (pulsed Doppler vs. pulse contour). Across all exercise trials regression results were found to be PCA = 1. 23 x Doppler-1. 38 with an r2 = 0. 51. In part II, eight young and eight older male healthy subjects participated in a head-up tilt experiment. Cardiac output comparisons were again performed during the supine and tilt conditions using pulsed Doppler and pulse contour cardiac output. Regression results revealed that PCA performed best during supine conditions and preferentially on the older subjects. In all instances, impedance-calibrated pulse contour analysis will provide reasonable beat-by-beat cardiac output within very narrow confines and will result in a progressively more significant bias as cardiovascular dynamics change. In addition, it appears that heart rate variability negatively influences beat-by-beat pulse contour cardiac output results, further limiting application of existing models.

Full textAbstract:
Physical inactivity is recognised as a major risk factor for non-communicable diseases such as hypertension, cardiovascular disease, diabetes and cancer. Current recommendations for participation in physical activity are 30 minutes or more of moderate-intensity physical activity on most, but preferably all days of the week. The aim of the study was to determine the effect of a physical activity programme on weight, blood pressure, body mass index and body fat classification among high school learners through a short-term physical activity intervention programme.

Publico-068.pdf: 848593 bytes, checksum: faea7296d3b3e87c6a1212049c181df8 (MD5)Introdução: A Síndrome de Marfan (SM) é uma doença de herança autossômica dominante decorrente de mutações no gene da fibrilina 1 no cromossomo 15, e pode apresentar manifestações esqueléticas, oculares, cardiovasculares entre outras. A velocidade de onda de pulso(VOP) é utilizada como um índice da elasticidade e rigidez arterial e está relacionada as propriedades elásticas da parede vascular. A pratica de exercício é limitada para esta população. Objetivo: Avaliar o efeito agudo de exercício submáximo em pacientes portadores de SM sem dilatação da aorta ou no máximo com dilatação leve deste vaso e o comportamento das variáveis fisiológicas. Casuística e Método: A VOP e variáveis fisiológicas foram avaliadas antes e após a realização de um esforço submáximo em 33 pacientes com SM e 18 controles. Resultados: A VOP no grupo com SM foi de 8,51±0,58 m/s no repouso e de 9,10±0,63 m/s ao final do exercício (p=0,002) e no grupo controle de 8,07±0,35 m/s no repouso e 8,98±0,56 m/s ao final (p=0,004). A análise comparativa da VOP entre os grupos controle e os pacientes com SM no repouso (p=0,519) e ao final do esforço (p=0,866) não se mostrou diferente. Os valores finais da freqüência cardíaca do grupo controle ficaram 10% acima dos indivíduos com SM (p = 0,01). A pressão arterial sistólica final foi superior no grupo controle (p=0,02). O lactato não se mostrou diferente e o tempo de exercício foi superior no grupo controle(p=0,01). Conclusão: O comportamento da distensibilidade aórtica foi semelhante, nos pacientes com SM sem ou com dilatação leve da aorta, ao grupo controle. Todavia as respostas cronotrópicas e pressóricas foram inferiores.
Purpose: Marfan syndrome is a dominant autosomal disease provoked by mutations of gene of fibrillin 1, chromosome 15, and may exhibit skeletal, ocular, cardiovascular and other manifestations. Pulse wave velocity (PWV) is used as a measure of arterial elasticity and rigidity and is related to the elastic properties of the vascular wall. As the practice of exercise is limited in this population, it was of our interest to analyze the acute effect of moderate to intensive exercise on patients with Marfan syndrome with either no dilatation of the aorta or a maximum of mild dilatation of this vessel. Methods: PWV and physiological variables were evaluated before and after the performance of sub-maximal exercise in 33 patients with Marfan syndrome and 18 controls. Results: PWV in the group with Marfan syndrome was 8.51±0.58 m/s at rest and 9.10±0.63 m/s at the end of the exercise (p=0.002); in the control group, PWV was 8.07±0.35 m/s at rest and 8.98±0.56 m/s at the end of exercise (p=0.004). The comparative analysis between groups regarding PWV at rest (p=0.519) and at the end of exercise (p=0.866) revealed no statistically significant differences. The final heart rate values in the control group were 10% higher than values in the group with Marfan syndrome (p = 0.01). Final systolic arterial pressure was higher in the control group (p=0.02). There was no difference in lactate between groups. Exercise time was greater in the control group (p=0.01). Conclusions: The behavior of aortic distensibility was similar in the patients with Marfan syndrome without or with mild dilatation of the aorta to that of the control group. The chronotropic and pressure responses were lower in patients than in control group.

Previous issue date: 2015-08-11In Goiás, the Ecological walk takes place annually and is an unique event for its distance (310km) and dynamics of performance (average of 62km-day for 5 days, average speed 7.6Km-h). Although the beneficial effects of moderate exercise are well known, the effects of intense exercise with long duration, as the Ecological walk, have not been well studied. This study aimed to verify the effects of prolonged exercise in central blood pressure and the correlation of these parameters with age. A total of 25 men were included in the study. The central blood pressure was measure datbaseline (A0), on the 2nd (A2), 3rd (A3) and 4th (A4) days of walk after the daily stop for night rest. The following parameters were measured: peripheral and central systolic and diastolic blood pressure, peripheral and central pulse pressure, pulse pressure amplified, 75% augmentation index, pulse wave velocity and vascular resistance. An oscillometric device from Mobil The Graphi® (IEM Stolber, Germany) was used. To compare the parameters between the daily measurements we used ANOVA for repeated measures followed by Bonferrroni post hoc and Pearson test for correlation. We considered significant p<0.05. We assessed 25 athletes with mean age 45.3±9.1.Central systolic blood pressure, reduced from A0 (113.8±2.1mmHg) to A3 (105.7±1.6mmHg) (p=0.035) and increased from A3 (105.7±1.6mmHg) to A4 (111.5±1.6mmHg) (p=0.006). The central diastolic blood pressure reduced from A0 (80.3±1.9mmHg) to A3 (74.3±1.5mmHg) (p=0.018)and A2 (78.6±1) to A3 (74.3±1.5mmHg) (p=0.036) and increased from A3 (74.3±1.5mmHg) for A4 (78.6±1.7mmHg) (p=0.014). The peripheral systemic blood pressure decreased from A0 (127.9±2.6 mmHg) to A2 (115.6±1.9mmHg) (p=0.002); to A3 (115.6±1.7mmHg) (p=0.003) and A4 (118.6±1.5mmHg) (p=0.007). The peripheral diastolic blood pressure reduced from A0 (78.7±1.9mmHg); from A3 (73.0±1.4mmHg) (p=0.018); A2 (77.4±1.1mmHg) to A3 (73.00±1.4mmHg) (p=0.040); and increased from A3 (73.0±1.4mmHg) to A4 (77.4±1.6mmHg) (p=0.010). The variables correlated with age were the central systemic blood pressure (A0), Peripheral pulse pressure (A3) and pulse wave velocity. Blood pressure decreased in the early days of walking, returning close to baseline at the end of the competition. Pulse wave velocity was strongly correlated with age.
Em Goiás, a caminhada Ecológica ocorre anualmente e é um evento único por sua distância (310 km) e dinâmica de realização (média de 62km-dia em 5 dias, média de 7,6 km-h). Apesar de os efeitos benéficos do exercício moderado serem bem conhecidos, os resultados de exercícios intensos e de longa duração, como a Caminhada Ecológica, ainda não foram muito estudados. O presente estudo teve o objetivo de verificar os efeitos do exercício físico prolongado nos parâmetros da medida central da pressão arterial e correlacionar esses parâmetros com a idade. Participaram do estudo 25 homens. Foi efetuada a medida central da pressão arterial para avaliar a participação (A0), nos 2º (A2), 3º (A3) e 4º (A4) dias de caminhada, após a parada diária para descanso noturno. Com essa medida foram obtidos os seguintes parâmetros: pressão arterial sistólica e diastólica periférica e central, pressão de pulso periférica e central, pressão de pulso amplificada, augmentation índex 75%, velocidade de onda de pulso e resistência vascular. Foi utilizado o dispositivo oscilométrico Mobil O Graphi® (IEM, Stolber, Alemanha). Para a comparação dos parâmetros entre os dias avaliados, foi usada a ANOVA para medidas repetidas, seguida de post hoc de Bonferrroni e para a correlação foi aplicado o teste de Pearson. Considerou-se como significativo p<0,05. Foram considerados 25 atletas com idade média de 45,3±9,1 anos. A medida central da pressão arterial sistólica reduziu de A0 (113,8±2,1mmHg) para A3 (105,7±1,6mmHg) (p=0,035) e aumentou de A3 (105,7±1,6mmHg) para A4 (111,5±1,6mmHg) (p=0,006). A medida central da pressão arterial diastólica diminuiu de A0 (80,3±1,9 mmHg) para A3 (74,2±1,0mmHg)(p=0,018) e A2 (78,2±1,9) para A3 (74,3±1,5mmHg) (p=0,036) e aumentou da A3 (74,3±1,5mmHg) para A4 (78,6±1,7mmHg) (p=0,014). A medida da pressão arterial sistólica periférica apresentou redução de A0 (127,9±2,6mmHg) para A2 (115,6±1,9mmHg) (p=0,002) para A3 (115,6±1,7mmHg) (p=0,003) e para A4 (118,6±1,5mmHg) (p=0,007). A medida periférica da pressão arterial diastólica reduziu de A0 (78,7±1,9mmHg) para A3 (73,0±1,4mmHg) (p=0,018); de A2 (77,4±1,1mmHg) para A3 (73,00±1,4mmHg) (p=0,040) e aumentou de A3 (73,0±1,4mmHg) para A4 (77,4±1,6mmHg) (p=0,010). As variáveis que apresentaram correlação com a idade foram a pressão arterial sistólica central (A0), a pressão de pulso periférica (A3) e a velocidade de onda de pulso. A pressão arterial teve queda nos primeiros dias de caminhada, retornando próxima aos valores basais no final do percurso. A velocidade de onda de pulso correlacionou-se fortemente com a idade.

Full textAbstract:
O transplante cardíaco permanece sendo o procedimento de escolha para a insuficiência cardíaca refratária, apresentando resultados favoráveis em termos da sintomatologia, qualidade de vida e sobrevida desses pacientes. A hipertensão arterial sistêmica aparece como a comorbidade de maior incidência neste grupo de pacientes, chegando a 95% após cinco anos. O efeito do exercício físico sobre a dinâmica do comportamento tensional na monitorização da pressão arterial ambulatorial durante 24 horas (MAPA-24h) e da rigidez arterial não tem sido estudado neste grupo de pacientes. Nós avaliamos os efeitos da atividade física aeróbia sobre a dinâmica do comportamento tensional na MAPA-24h, rigidez arterial e as variáveis cardiovasculares em indivíduos após um ano de transplante cardíaco. Trinta e nove pacientes de ambos os sexos, randomizados para grupo treino (GT) (n = 29; 45 ± 13 anos) ou grupo controle (GC) (n = 9; 51 ± 11 anos) realizaram, antes e após o período de 12 semanas de seguimento, exames de MAPA-24h, velocidade de onda de pulso carótido-femoral (VOP) e teste de esforço cardiopulmonar, com coletas de amostras sangüíneas para dosagem de norepinefrina (Nor) (repouso e pico). Treinamento físico aeróbio foi realizado três vezes por semana, sendo duas supervisionadas e uma não supervisionada, durante 40 minutos inicialmente com a frequência cardíaca monitorada em 80% do ponto de compensação respiratória. O GT apresentou redução significativa da pressão arterial sistólica nos períodos da média das 24 horas (de 120 ± 11 para 116 ± 14mmHg, p<0,05) e vigília (de 123 ± 11 para 118 ± 13mmHg, p<0,05). A pressão arterial diastólica apresentou redução significativa para os três períodos sendo na média das 24 horas (de 81 ± 9 para 74 ± 9mmHg, p< 0,001), vigília (de 83 ± 9 para 75 ± 10mmHg, p<0,001) e noturno ( de 77 ± 10 para 71 ± 10mmHg, p<0,001). A VOP não apresentou redução significativa após o período de seguimento para ambos os grupos; GT (de 10,0 ± 1,9 para 9,7 ±1,9m/s, p = ns) e GC (de 10,3 ± 2,2 para 10,4 ± 2,8m/s, p = ns), porém os níveis da Nor tiveram aumento significativo no pico do exercício no grupo GT (de 2386 ± 1274 para 3292 ± 1410 pg/ml p<0,01) e também em relação ao grupo GC pós seguimento (3292 ± 1419 versus 2178 ± 659 pg/ml, p<0,05). O treinamento físico aeróbio reduziu a pressão arterial sistólica/diastólica em 4,7/7,5 mmHg durante a vigília e em 3,5/5,8 mmHg durante o sono após TX, além de melhorar o condicionamento cardiorrespiratório com aumento do VO2pico, FCmáx e do tempo de exercício.Cardiac transplantation remains the procedure of choice for refractory heart failure, with favorable results in terms of symptoms, quality of life and patient survival. Hypertension appears as a higher incidence of comorbidity in this group of patients, reaching 95% after five years. However, the effect of exercise training in the behavior of 24-hour ambulatory blood pressure monitoring (ABPM) and arterial stiffness has not been studied in this group of patients. We assessment the effects of aerobic physical activity in the behavior of ABPM, arterial stiffness and cardiovascular variables in patients being heart transplanted for a year or more. Thirty-nine patients of both genders were evaluated, then randomized to either training group (TG) (n = 29, 45 ± 13 years) or control group (CG) (n = 9, 51 ± 11 years) and reevaluated after 12 weeks of follow-up. Pre and post evaluations combined examinations of ABPM, carotidfemoral pulse wave velocity (PWV) and graded exercise test, with collections of blood samples for measurement of norepinephrine (Nor) (rest and peak). Aerobic exercise was performed in the TG three times-a-week, two supervised and one unsupervised for 40 minutes initially at an intensity of 80% of heart rate achieved at the respiratory compensation point. The TG showed a significant reduction in systolic blood pressure during average of 24 hours (from 120 ± 11 to 116 ± 14mmHg, p < 0.05) and diurnal cycle (from 123 ± 11 to 118 ± 13mmHg, p<0.05). Diastolic blood pressure decreased significantly for the three periods, the average of 24 hours (from 81 ± 9 to 74 ± 9mmHg, p<0.001), diurnal cycle (from 83 ± 9 to 75 ± 10mmHg, p < 0.001) and nighttime (from 77 ± 10 to 71 ± 10mmHg, p < 0.001). The PWV showed no significant reduction after the followup period for both groups; TG ( from 10.0 ± 1.9 to 9.7 ± 1.9m/s, p = ns) and CG (from10.3 ± 2.2 to 10.4 ± 2.8m/s, p = ns) and the levels of the Nor had a significantly higher peak exercise in TG (from 2386 ± 1274 to 3292 ± 1410 pg/ml p <0.01) and also in relation to the control group after follow-up (3292 ± 1419 versus 2178 ± 659 pg / ml, p <0.05). The exercise training reduced both systolic and diastolic blood pressure in 4.7 and in 7.5 mmHg during daytime, respectively. Reduction also happened during nighttime in 3.5 and in 5.8 mmHg for these variables, respectively. Exercise training improved VO2peak, HRmax and time of exercise (cardiorespiratory fitness) after follow-up, as well.

La réhabilitation respiratoire (RR) est recommandée dans la prise en soin des patients atteints d’un handicap ventilatoire afin d’améliorer leur qualité de vie. Malgré une efficacité clairement établie, très peu de patients en bénéficient et les modalités optimales d’entrainement restent à définir. L’utilisation des outils existants et des nouveaux outils pour optimiser l’accès au programme et ses effets représentent des développements majeurs qui méritent d’être évalués. Dans le cadre de cette thèse, nous avons cherché à aborder ces deux problématiques (1) en tentant de proposer un modèle de RR délocalisée hors des centres tout en évaluant les freins à ce modèle et (2) en explorant la place de différents adjuvants à la RR afin d’en optimiser les bénéfices. Dans la première partie, nous avons montré, à travers plusieurs études rétrospectives et une contribution originale prospective multicentrique, que le test stepper de six minutes peut être utilisé pour prescrire l’entrainement en endurance, particulièrement pour les patients présentant une forme légère à modérée de bronchopneumopathie chronique obstructive (BPCO), mais pas pour prescrire le renforcement musculaire. Par ailleurs, nous avons montré dans une population de 105 patients adressés en RR que l’utilisation d’un dispositif de telemonitoring était faisable, valide et largement accepté. Enfin, nous avons exploré la prévalence des dysfonctions cognitives, autre conséquence systémique de la BPCO qui pourrait compromettre la délocalisation du programme, et avons montré que cette prévalence était très élevée (environ 75% des patients) mais que ces troubles cognitifs pouvaient s’améliorer après la RR et ne semblaient pas influencer l’utilisation d’un dispositif de telemonitoring. Dans la seconde partie, nous avons évalué la place de différents adjuvants à la RR utilisés pour en potentialiser les bénéfices. Dans une étude en cross-over menée chez 21 patients atteints de BPCO, nous avons montré que la ventilation non invasive ne permettait pas d’améliorer la capacité à l’exercice en endurance en raison d’une limitation technologique du ventilateur. A travers une étude contrôlée randomisée multicentrique menée chez 73 patients atteints de BPCO sévère à très sévère, nous avons montré que la stimulation électrique excito-motrice à domicile, réalisée en plus d’un programme de RR, n’apportait pas davantage de bénéfices sur la qualité de vie ou la capacité à l’exercice. Enfin, à travers une étude randomisée en cross-over et en double aveugle menée chez 10 patients, nous n’avons pas pu montrer l’intérêt de la stimulation électrique nerveuse transcutanée pour améliorer leur capacité à l’exercice en endurance. Enfin, dans la dernière partie, nous avons présenté les recherches actuellement menées au sein de notre laboratoire, faisant suite aux contributions originales décrites au cours de cette thèse, ainsi que de nouvelles pistes de recherche afin de poursuivre les thématiques explorées. Ainsi, deux revues de littérature et méta-analyses (l’une d’elle portant sur le haut débit nasal et l’autre sur l’utilisation des technologies de santé avancées pour réaliser la RR respiratoire à domicile) serviront de base pour de futurs travauxPulmonary rehabilitation (PR) is recommended in the management of subjects with ventilatory impairment to improve their quality of life. Although a large body of evidence support its use, only few subjects benefit from it and the optimal training modality has not been determined yet. In this context, the use of new and existing tools to optimize access as well as the effects of the program are major developments that deserve to be studied. As part of this thesis, we sought to explore these two major issues (1) by considering a rehabilitation model relocated outside the PR centres while assessing the obstacles to this model and (2) exploring the effectiveness of different add-on to PR in further optimizing the benefits of the program. In the first part, we have shown, through several retrospective studies and an original prospective multicentre contribution, that the six-minute stepper test can be used to prescribe endurance training, particularly for those patients with a mild to moderate chronic obstructive pulmonary disease (COPD), but not to prescribe muscle strengthening. Furthermore, we have shown in a cohort of 105 subjects referred for PR that the use of a remote tele monitoring device was feasible, valid and widely accepted. Finally, we explored the prevalence of cognitive dysfunction, another systemic impairment of COPD that could compromise the relocation of the program, and showed that it was a very common condition (around 75% of the subjects) but that it could improve following PR and did not seem to influence the use of a remote tele monitoring device. In the second part, we evaluated the effects of different add-on used to potentiate the benefits of the PR program. In a cross-over study of 21 COPD patients, we showed that non-invasive ventilation did not improve endurance exercise capacity due to technological limitation of the ventilator. Through a multicentre randomized controlled study carried out in 73 patients with severe to very severe COPD, we have shown that neuromuscular electrical stimulation at home, performed in addition to a PR program, did not provide further benefits on quality of life or exercise capacity. Finally, through a randomized cross-over double-blind study carried out in 10 patients, we were unable to show the effectiveness of transcutaneous nerve electrical stimulation in improving their endurance exercise capacity. Finally, in a last part, we highlighted the research currently carried out in our laboratory following the original contributions described during this thesis, as well as new area of research in order to pursue the themes explored. Thus, two systematic reviews and meta-analysis (the first about nasal high flow therapy in subjects with stable COPD and the second about the use of advanced telehealth technologies to deliver PR) will serve as a basis for future research

Introduction: After eccentric exercise, it often causes rupture of sarcomere and cells, orthostatic hypotension, severe muscle fiber damage, muscle swelling, joint activity angle reduction, isokinetic concentric strength decrease, the creatine kinase and the red blood cells are sharply increased and the pulse wave velocity is increased. The pulse wave velocity is regarded as an important index for evaluating cardiovascular diseases. When the muscle group was stretched, the maximum isometric contraction may reduce the muscle damage caused by the maximum eccentric contraction training in the second round, and the protective effect has been produced. It’s no idea about whether the pulse wave velocity was affected by the maximum eccentric contraction training. Purpose: This study investigated the protection of the knee extensor by performing one rounds of maximum isometric exercise, and then undergo one round of 60 maximum eccentric contraction training two days later. Methods: Sixteen healthy males were randomly placed into the training group and the control group (n=8 per group). After performing one round of maximal isometric exercise, the training group had performed maximum isometric centrifugal training for 60 times (10 times/group x 6 groups) in the second round. The observation period was a total of 4 days before and after the first round, including: the pretest (Pre-D2 & Pre-D1), the training day (D0), and the recovery observation period after the training (D1). The observation period of second round was a total of 7 days before and after the maximal isokinetic eccentric exercise, including: the pretest (Pre), training day (D0) and 5 days (D1 ~ D5) recovery observation period, the interval was 24 hours. Observe the dependent variables of muscle injury indicators at each time point: maximum isokinetic concentric strength (ISOK), range of motion (ROM), limb circumference(CIR), carotid-femoral pules wave velocity (cfPWV), diastolic blood pressure (DBP), systolic blood pressure (SBP) and heart rate (HR). Results: (1) After the two maximal isometric trainings, the training group did not cause obvious muscle damage (p>.05). (2) The training group and the control group were no significant difference between the cfPWV and other dependent variables after one round of maximum eccentric contraction training (p>.05). There were significantly different in days after the second round in the training and the control group (p<.05). Conclusion: After maximum eccentric contraction training, the knee flexor caused significant muscle damage. But performing 2 maximal isometric training before the maximum eccentric contraction training was not produced influence in pulse wave velocity.

Purpose: The purpose of the study is to compare the region pulse wave velocity (PWV) after aerobic exercises using treadmills, elliptical machines and Core X. Method: The participants, including 30 college students (age 19.87 ± 1.68 yrs, height 167.45 ± 7.20 cm, weight 63.16 ± 11.60 kg), received incremental maximal exercise to exhaustion to obtain the heart rate maximal. According to the balance way of order, the participants accepted three kinds of aerobic exercise (70% HRR HRC with treadmill, 70% HRR HRC fixed frequency 50rpm with elliptical machine and 40rpm fixed frequency with Core X) respectively for 30 minutes. After 30 minutes of rest after exercise, Ultrasonic Doppler Flow Detector was used to measure pulse wave velocity. Data was progressed by One-way ANOVA to compare the difference among the effects of 3 aerobic exercise on the carotid-femoral (cf), brachial-ankle (ba) and femoral-ankle (fa) PWV. The significant level was set at α=.05. Result: There were no significant differences on pulse wave velocity of resting and after aerobic exercise from cfPWV, baPWV and faPWV cfPWV after elliptical machines and Core X aerobic exercise were significant different (p<.05). Both baPWV and faPWV after aerobic exercise of treadmills, elliptical machines and Core X had no significant difference. Conclusion: Central arterial compliance was indices with elliptical aerobic training. The effect of arterial compliance with Core X and treadmill aerobic exercise that no difference.

Background: with the increasing prevalence of cardiovascular disease in modern society, pulse wave velocity (PWV) and adiponectin are both predictive markers for cardiovascular diseases in clinical settings. Adiponectin has been found vessel- protective that could exert anti-inflammatory effects and ameliorate atherosclerosis. However, it is still unknown whether inflammatory responses induced by eccentric exercise would interact with adiponectin as well as PWV. Purpose: to determine the effects of muscle damage induced by acute downhill running and eccentric resistance exercise on adiponectin and PWV as well as the relationship between adiponectin and PWV. Methods: eighteen apparent healthy males were recruited to participate this study. Participants were randomly assigned into downhill running (EE, n=9) and eccentric resistance exercise (RE, n=9) groups. Maximal oxygen uptake (VO2peak= 50.5 ± 7.6 ml/kg/min) of EE and one prepetition maximum of inclined leg press (1RM= 222.4 ± 55.2 kg) were determined prior to experiment. EE group performed 30 minutes of the downhill running at -10° of slope that could elicit 75% of individual VO2peak whereas RE group performed 120% 1RM eccentric contractions for 6 reps × 10 sets. PWV, serum adiponectin, creatine kinese (CK), and C-reactive protein (CRP) were measured pre-exercise, 90 minutes, 24 and 48 hours post-exercise. Results: CK of EE and RE group were significantly higher than the pre-exercise (p＜.05); PWV of two groups were also significantly higher on 24 (5.47 ± 0.59 m/s) and 48 hours post-exercise (5.44 ± 0.68 m/s) as compared to pre-exercise (5.18 ± 0.47 m/s) (p＜.05) respectively. Compared with pre-exercise, adiponectin and CRP were no altered after performing eccentric exercise (p＞.05). However, PWV was negative correlated with adiponectin on 24 hours post-exercise (r= -.501) (p＜.05). There were no significant differences among groups in all dependent variables (p＞.05). Conclusion: muscle damage induced by an acute bout of downhill running and eccentric resistance exercise both increased PWV, but did not altered adiponectin response. This transient aortic arterial inflammatory may not directly relate to adiponectin.

Full textAbstract:
BACKGROUND: Colorectal cancer incidence and mortality rates are rising and are still one of the most common cancers worldwide. Its risks are associated with the Western Lifestyle, important facets of this being increase physical inactivity and excess body weight. In sync with colorectal cancer’s increasing rates are obesity rates that are rising in both developed and developing countries. Obesity has been linked to several causes of death that includes cardiovascular disease and certain cancers. Studies have shown the benefits of exercise overtly in alleviating cardiovascular diseases but now have increasing evidence of its benefits in helping with cancer. Some studies have examined the effects of physical activity in colon cancer and have found a link between increase minutes of exercise weekly can slow cancer cell proliferation in colon crypts cells. Myokines are a newly discovered class of proteins that are produced by muscles and have multiple functions. One of those function is its anti-neoplastic activity against certain cancer cell types. Certain myokines evoke an anti-neoplastic effect on cancer, but there has not been an overwhelming agreement within the scientific community.
OBJECTIVE: To investigate the anti-proliferative effects of exercise myokines produced by C2C12 cells in colorectal cancer cell lines: HCT116 and HT29, by looking at changes in protein expression through western blot analysis and protein arrays.
METHODS: C2C12 cells were grown in cell culture plates and differentiated into myotubules. Myotubules were subjected to Electronic Pulse Stimulation using an apparatus called C-Pace by Ion Optix to generate myokines. Treat HCT116 and HT29 cell lines with exercise myokines and a control treatment and ultimately harvest their protein lysate for western blot analysis and protein array analysis.
RESULTS: HCT116 treated with exercise myokines with different dilutions (1:25, 1:50, 1:100) a demonstrated significantly decreased proliferation (p<0.0001). HT29 treated with exercise myokines (1:25 dilution) also demonstrated a significant decrease in proliferation (p<0.0001). Western blot analysis of HCT116 treated with exercise myokines showed significantly lower expression in pRb (p<0.05), PCNA (p<0.05), and cyclin D1 (p<0.05). Western blot analysis of HT29 treated with exercise myokines revealed significant expression downregulation in exercise myokine treatment in PCNA (p<0.05), p42/p44 (p<0.05), pRb (p<0.0001) and Cyclin D1 (p<0.05). Human Phospho-Kinase Array demonstrated downregulation of the following proteins in HT29 cells treated with exercise myokines: GSK-3α/β, STAT3, EGFR, p53, PDGF Rβ, Src, PRAS40, WNK1, and JNK 1/2/3. Lastly, HT29 treated with exercise myokines showed downregulation of the p-EGFR and pHGFR as a result of the Human Phospho-RKT Array.
CONCLUSION: Our data demonstrate that exercise myokines produced by Electric Pulse Stimulation of C2C12 cells have an anti-proliferative effect on colorectal cancer cell lines HCT116 and HT29. Further studies should be pursued to identifying and linking anti-proliferative properties to a specific myokine protein and confirming a pathway that this specific myokine exerts its effects.

Title: The CVS method as a diagnostic of the cardiovascular system Objective: The aim of this thesis is to introduce the CVS (cardiovascular system) method as a potential diagnostic method to detect the overloading of the heart muscle, and thereby increased susceptibility to subsequent myocardial infarction and hypertension. Method: This thesis presents a data analysis on different groups of people, which were provided to us during the development of the CVS method. These were several groups of healthy individuals (athletes) and three groups of patients suffering from problems with the cardiovascular system (colaps conditions, obesity and hypertension). The groups were measured for their values of the heart rate and blood pressure at rest and during exercise on a bicycle ergometer. Subsequently the energy required to pump blood to the heart muscle and climbing speed pulse pressure depending on the heart rate was evaluated. Results: The CVS method shows differences in the energy consumption of the heart muscle in various groups of people. The results showed that at the same level of exercise the load of the heart muscle is higher by patients than by athletes. Considering the samples that we had available, the CVS method proved its diagnostic value when evaluating the overall effectiveness of the...

Contexto: As recomendações internacionais preconizam que um programa de reabilitação cardíaca (PRC) deve ter um programa de exercício que contemple treino aeróbio e treino de força. Nos estudos realizados, a prática de treino aeróbio e de força conduz a mais alterações que traduzem-se em melhorias a nível das variáveis cardiorrespiratórias e hemodinâmicas no início do PRC. Por outro lado, poucos estudos avaliam as adaptações a longo prazo em participantes com doença arterial coronária (DAC) num PRC.
Objetivo: Analisar o comportamento das variáveis hemodinâmicas, pressão arterial sistólica de repouso (PASrep), pressão arterial sistólica máxima (PASmáx), pressão arterial diastólica de repouso (PADrep), frequência cardíaca de repouso (FCrep), frequência cardíaca máxima (FCmáx), potência circulatória de pico (PCP), e das variáves cardiorrespiratórias, consumo de oxigénio de pico (VO2pico) e oxigénio de pulso (O2Pulso) ao longo de 3 anos em participantes com vários anos num PRC.
Metodologia: Estudo observacional prospetivo do comportamento das variáveis hemodinâmicas e cardiorrespiratórias ao longo de 3 anos consecutivos, numa amostra de 8 participantes do sexo masculino com DAC com uma média de 8 ± 5,82 anos de participação no PRC. As variáveis foram obtidas e calculadas através dos registos anuais das provas cardiorrespiratórias realizadas entre 1995 e 2018.
Resultados: Após anos de participação num PRC, as variáveis cardiorrespiratórias e hemodinâmicas analisadas em 3 anos consecutivos, os participantes mantêm a sua capacidade cardiorrespiratória e de independência para as suas atividades diárias.
Conclusão: Uma longa participação num PRC, permite que os participantes com DAC mantenham a sua capacidade cardiorrespiratória e as adaptações hemodinâmicas relacionadas com a prática de exercício físico.Background: The international guidelines recommend that a cardiac rehabilitation program (CRP) should have a exercise program with aerobic and resistance training. Several studies have demonstrated that in the beginning of a CRP, combined training have better improvements in cardiorrespiratory and haemodinamics variables but few studies foccused on the adaptations after years of exercise in participants with coronary artery disease (CAD). Objetive: Analysis of haemodinamics variables, rest systolic blood pressure (SBPrest), maximum systolic blood pressure (SBPmax), rest diastolic blood pressure (DBPrest), rest heart rate (HRrest), maximum heart rate (HRmax) , peak circulatory power (PCP) and cardiorrespiratory, peak oxygen uptake (VO2peak) and oxygen pulse (O2 Pulse) for 3 years along in participants with many years of CRP. Methods: A prospective observational study of haemodinamics and cardiorrespiratory variables in 3 years along, in a sample with 8 male participants with coronary artery disease with na average of 8 ± 5,82 years of CRP. The variables were obtained and calculated from the cardiopulmonary tests anual reports between 1995 and 2018. Results: After years in a CRP, a 3 year analysis of the variables, the participants mantained their cardiorrespiratory fitness and independence for their daily routines. Conclusion: With a long participation in a CRP, the participants maintained their exercise capacity and had hemodynamics adaptations related to exercise practice.
