Abstract:

Il Powerlifting è una disciplina internazionale in cui gli atleti si impegnano a sollevare un ammontare massimale di peso in tre diversi esercizi: lo squat, la distensione su panca e lo stacco da terra. Nonostante, in Italia, siano molte le persone che vorrebbero dedicarsi a questa disciplina non è sempre facile trovare un istruttore qualificato nella propria zona. Molti atleti, quindi, eseguono studi sull’argomento tramite libri o corsi online per poi svolgere gli allenamenti in autonomia, rendendo così complesso capire se gli esercizi che si stanno praticando sono eseguiti in maniera corretta. Attorno a queste problematiche si inserisce il presente lavoro di tesi, volto a fornire un’analisi della validità dello squat nel Powerlifting, tramite l’utilizzo di sensori inerziali. In particolare, è stato acquisito un soggetto (47kg, 158cm) con sensori inerziali e stereofotogrammetria, considerata strumento Gold Standard. Successivamente, i dati raccolti sono stati elaborati con diversi metodi e confrontati con l’approccio stereofotogrammetrico che considera per l’articolazione dell’anca il Grande Trocantere e per quella di ginocchio la porzione più prossimale della rotula (Protocollo PG-GT). Questo, allo scopo di valutare se i sensori inerziali sono in grado di stimare la validità dello squat commettendo un errore di al massimo 3°. Il metodo che considera la porzione più prossimale della rotula (PG) e la spina iliaca anteriore superiore (SIAS), consiste in un approccio che tende maggiormente a sovrastimare l’angolo della coscia rispetto alla verticale rispetto al metodo Gold Standard, utilizzare questo metodo nella pratica, in sostituzione all’approccio PG-GT, significa quindi valutare come valide un numero maggiore di prove. Gli algoritmi implementati che utilizzano i sensori inerziali non permettono di valutare la validità dello squat nel Powerlifting entro un errore massimo di 3°.

Abstract:

Daily undulating periodization represents an increasingly popular trend in exercise science with which a traditional model has been established. Tiered daily undulating periodization pairs the DUP approach with a tiered training system which allows volume and intensity to be more evenly distributed throughout a given graining cycle. The concept of tiered daily undulating periodization is a novel form of periodization and has not been investigated. As such, a comparison of traditional and tiered daily undulating periodization has yet to be examined. Therefore, the purpose of this study was to compare the effects of traditional and tiered daily undulating periodization models as they relate to strength adaptations in trained males. Twenty-seven resistance trained males (22.0 ± 4.5 years) completed an 8 week resistance training protocol. Subjects were randomly assigned to either the traditional daily undulating periodization group (DUP, n = 12) or tiered daily undulating periodization group (TDUP, n = 15). Participants were recruited from the campus recreation center and met the minimum strength requirements of bench pressing their bodyweight, squatting 125% of their bodyweight, and deadlifting 150% of their bodyweight. Strength measures included squat 1RM, bench press 1RM, deadlift 1RM, powerlifting total, and Wilk’s Coefficient. Each variable was measured at baseline and again after the 8 week training period. Each group performed the same number of sets, reps, and exercises throughout each training week. DUP specified all exercises in a given training bout to be performed the same intensity and repetition scheme. TDUP specified performance of one high intensity exercise each day with each subsequent exercise being performed with lower intensity and differing repetition scheme. Data was analyzed via a 2x2 mixed factorial ANOVA with the alpha criterion for significance set at 0.05. There were no significant differences between groups at baseline and no significant differences were observed between groups for total volume or intensity. With respect to strength dependent variables, there was a main effect for time (p = <0.001) for back squat 1RM (DUP pre = 140.5 ± 33.9 kg, DUP post = 163.3 ± 29.8 kg; TDUP pre = 147.3 ±34.0 kg, TDUP post = 166.5 ± 30.7 kg), bench press 1RM (DUP pre = 104.2 ± 12.9 kg, DUP post = 114.9 ± 14.2 kg; TDUP = 110.4 ± 12.7 kg, TDUP post = 120.6 ± 11.9 kg), deadlift 1RM (DUP pre = 177.7 ± 26.4 kg, DUP post = 194.1 ± 20.2 kg; TDUP pre = 169.6 ± 37.5, TDUP post = 188.3 ± 37.5), powerlifting total (DUP pre = 422.4 ± 67.8 kg, DUP post = 472.4 ± 60.6 kg; TDUP pre = 427.1 ± 79.2 kg, TDUP post = 476.5 ± 74.1 kg), and Wilk’s score (DUP pre = 287.5 ± 49.3, DUP post = 320.0 ± 45.6; TDUP pre = 298.3 ± 45.8, TDUP post = 331.6 ± 38.7). However, no interaction effects were observed between DUP and TDUP for any of the strength dependent variables. These results suggest that 8 weeks of tiered DUP resistance training leads to similar gains in strength compared to the traditional DUP model in trained males. This could be a result of the similar workload between both groups. While not significant, traditional DUP may be more efficacious for improving back squat 1RM (DUP = 16%; TDUP = 13%), while TDUP may elicit greater strength gains in the deadlift (DUP = 9%; TDUP = 12%). Furthermore, this study demonstrates that exercise order and training intensity can be manipulated throughout each training session according to personal preference while maintaining strength adaptations within a DUP model. Lastly, dropout rates in this study lead researchers to conclude that the DUP protocols investigated should be transient and not used as a long term training approach.

Abstract:

Daily undulating periodization is a growing trend in the exercise science literature. Flexible daily undulating periodization allows for athletes to have some autonomy within a periodized training cycle and is a relatively new and unstudied concept. The comparison of a flexible and traditional daily undulating periodization program using trained males has not been examined in the literature. The purpose of this study was to compare the effects of Flexible and Traditional Daily Undulating Periodization models on powerlifting performance in trained males. 25 resistance-trained males (23±6 years; 79±22 kg) completed a 9-week resistance-training program and were randomly assigned to one of two groups: Flexible Daily Undulating Periodization (FDUP; N=14) or Daily Undulating Periodization (DUP; N=11). All subjects possessed a minimum of 6 months of resistance training experience & were required to squat 125% their bodyweight, bench press their bodyweight, and deadlift 150% their bodyweight. Dependent variables (DV) included bench press 1RM, squat 1RM, deadlift 1RM, Powerlifting total, and Wilk's Coefficient. Each DV was assessed at baseline and after the 9-week training program. The DUP group performed a hypertrophy workout on Monday, a power workout on Wednesday, and a strength workout on Friday. The FDUP group completed the exact same workouts in a given week, but were allowed to choose the order of the workouts. Data for each DV were analyzed via a 2x2 between-within factorial repeated measures ANOVA. The alpha criterion for significance was set at 0.05. There were no significant differences in total volume or intensity between groups. There was a main effect for time (p < 0.001) for 1RM Squat (FDUP pre = 132 ± 34 kg, FDUP Post = 148 ± 33 kg; DUP pre = 147 ± 31 kg, DUP post = 165 ± 25 kg), 1RM Bench Press (FDUP pre = 96 ± 20 kg, FDUP post = 102 ± 19 kg; DUP pre = 147 ± 31 kg, DUP post = 165 ± 25 kg), 1RM Deadlift (FDUP pre = 166 ± 41 kg, FDUP post: 181 ± 37 kg; DUP pre = 174 ± 25 kg, DUP post = 188 ± 29 kg), Powerlifting Total (FDUP pre = 394 ± 90 kg, FDUP post = 431 ± 84; DUP pre = 439 ± 71 kg, DUP post = 480 ± 69 kg), and Wilk's Coefficient (FDUP pre = 147 ± 25 kg, FDUP post = 304 ± 51; DUP pre = 299 ± 41, DUP post = 325 ± 38). There were no interaction effects between the FDUP and DUP for any of the variables assessed. 9 weeks of Flexible DUP leads to comparable gains in powerlifting performance when compared to a Traditional DUP program in trained males. This may be attributed to the fact that both groups performed similar volumes of work throughout the study. Specifically, FDUP improved squat 1RM by 12%, bench press 1RM by 7%, deadlift 1RM by 9%, powerlifting total by 9%, & Wilk's coefficient by 9%. Similarly, DUP improved squat 1RM by 12%, bench press 1RM by 8%, deadlift 1RM by 8%, powerlifting total by 9%, & Wilk's coefficient by 9%.

Abstract:

The contemporary training practices of powerlifters are presently being adopted by athletes from a variety of sports seeking to improve their performance. The aims of this PhD were to: 1) identify the contemporary training practices of powerlifters; 2) investigate the biomechanical stimulus the training practices create; and 3) assess whether the training practices have the potential to improve the athletic performance of general athletes The aims were achieved through the completion of five related studies. The first study employed questionnaires and interviews to indentify the contemporary training practices used by elite powerlifters. The results demonstrated that elite powerlifters used a wide variety of training practices, many of which would not have been attributed to the group based on previous literature. The practices were categorised based on their underlying mechanical principles so that the essential features could be investigated in the subsequent studies. A regression-based approach was used in the second study to identify the biomechanical variables associated with performance of common sporting tasks. Maximum force production, power, velocity and rate of force development (RFD) were shown to explain a large percentage of variation in performance of tasks such as sprinting, jumping and changing direction (adjusted R2 ranged from 0.43 to 0.86). These mechanical variables were then measured in a series of experimental studies to assess the potential of the contemporary powerlifting practices to improve athletes‟ physical performance. Assessments were based on a central paradigm in strength and conditioning that asserts that improvements in the ability to express biomechanical variables (e.g. force and power) are best obtained with training practices that maximise acute production of the same variable. Based on the categorisation of the mechanical principles underlying the assessed training practices, three experimental studies were conducted that investigated: 1) the practice of performing traditional resistance exercises at maximum velocity; 2) the effects of manipulating the external resistance through the use of variable resistance material (chain resistance) and an unconventional barbell (the hexagonal barbell); and 3) the effects of altering the movement strategy used to perform the squat. The results of the studies clearly demonstrated that each of the practices investigated could be used to substantially alter and in most cases enhance the biomechanical stimulus created. The practice of performing traditional resistance exercises at maximum velocity revealed that all key mechanical variables were significantly increased (p<0.05) compared with the standard practice of performing repetitions with a sub-maximum velocity. In addition, the results demonstrated that when performing a traditional resistance exercise such as the deadlift at maximum velocity, experienced resistance trained athletes could accelerate the load for the majority (75% to 90%+) of the movement. The second experimental study featuring the separate use of chain resistance and the hexagonal barbell to alter the characteristics of the external resistance demonstrated contrasting effects. The change in position of the external resistance when using the hexagonal barbell significantly (p<0.05) increased the participants' ability to produce high force, power, velocity and RFD values across a range of loads in comparison with the same movement performed with a traditional straight barbell. In contrast, the results from the study evaluating the effects of adding chain resistance showed that whilst force values were increased with the addition of chains, velocity, power and RFD values substantially decreased compared to standard repetitions performed with barbell resistance only. The results also demonstrated that the effects of the chain resistance were more noticeable with heavier chain and barbell loads. The final experimental investigated the effects of altering the movement strategy used to perform the back squat exercise. The results confirmed that changes to the movement strategy had a significant effect on a range of kinematic and kinetic variables. In particular, the contemporary techniques promoted by powerlifters resulted in substantial kinematic and kinetic changes at the hip and reduced kinetic output at the ankle joint. Collectively, the work from this PhD supports the selective use of contemporary powerlifting training practices for the development of athletic potential. Future research should build on the framework created in this thesis, progressing to longitudinal and ultimately implementation studies to increase the likelihood of transferring the results to practice.

Abstract:

In powerlifting the athletes compete to lift as much weight as possible in the squat, bench press and deadlift, pushing their bodies to extreme levels of strength. When lifting heavy weights, safety becomes an important concern, especially where the lifters can get injured by the barbell if a lift is unsuccessful. Today in the squat, the only safety mechanism available are the spotters, a team of officials who surround the lifter during competition. This product development project aims to improve the safety of lifters and spotters in competition. This project followed the CDIO process model, going through the four phases of conceive, design, implement, and operate. Using literature review, interviews, observations, ergonomic analysis, fault tree analysis gave insights and information, which then were comprised into a Product Design Specification. The design phase included idea generation using creative sessions, resulting a lot of ideas on how the problems could be solved. In the subsequent phases the ideas were developed using CAD, evaluated using FEM and usability testes, and narrowed down using the PDS. The result is a feasible conceptual solution that, with minimal changes on use improve the safety for lifters and spotters. The concept accomplishes this with mechanical barriers in the form of straps. The straps are mounted to steel beams that attaches to the uprights of the rack and reaches over the athlete, enclosing the barbell. The concept also includes a pair of extension legs, which attaches to the base of the rack, increasing the size of the footprint and provide additional stability. The solution is made to be retrofitted to already existing combo racks made by Eleiko. Key features of the concepts are the straps passively adjust in height when adjusting the height of the rack and the straps accommodate lifters with different grip widths when the rack is in the folded in position. I styrkelyft tävlar atleter i att lyfta så mycket vikt som möjligt i delgrenarna, knäböj, bänkpress och marklyft. Det göra att lyftarna pressar sina kroppar till extrema nivåer av styrka. När tunga vikter ska lyftas är säkerheten alltid en angelägenhet, speciellt med tanke på följderna av klämmas under en skivstång. I dagsläget finns det en säkerhetsmekanism för knäböj på en styrkelyftstävling. Klovarna, de funktionärer som omringar lyftaren på podiet har i uppgift att fånga vikten och hjälpa lyftaren tillbaka i racken om något går fel. Misslyckas dem med sin uppgift kan det ge ödesdigra konsekvenser. Målet med det här produktutvecklingsprojektet är att lösa det problemet och följaktligen att förbättra säkerheten för både lyftare och klovare på tävling. Projektet har använt processmodellen CDIO, en linjär process som består av fyra steg, conceive, design, implement och operate. Under conceive-fasen undersöktes problemet noggrannare. Med stöd av resultaten från litteraturstudier, intervjuer, observationer, ergonomisk analys och felträdsanalys upprättades en designspecifikation. Efter det genererades idéer i kreativa sessioner, vilket resulterade i ett brett spektrum av idéer och möjliga lösningar. I följande faser utvecklades idéerna till koncept med hjälp av CAD. De tidiga koncepten utvärderades sedan med FEM och användartester och skalades ner till ett slutgiltigt koncept med designspecifikationen som utgångspunkt. Resultatet av projektet är en konceptuell produktlösning, som med minimal påverkan på lyftare och klovare ökar säkerheten i knäböj. Konceptet åstadkommer det med nylonremmar som agerar mekaniska barriärer för skivstången. Remmarna sitter fast i en stålbalk som sträcker sig över lyftaren och monteras i stolparna på racket. Konceptet innehåller också ett par förlängningsben som fästs i basen av det befintliga racket. De förbättrar stabiliteten för racket genom att utöka fotavtrycket. Konceptet är tänkt att eftermonteras på befintliga styrkelyftsställningar från Eleiko. Nyckelfunktioner för konceptet är den passiva höjdjusteringen, höjden på remmarna justeras automatiskt när höjden på ställningen ställs in för lyftare av olika längd. Konceptet tillåter även att lyftare att knäböja med brett grepp om stången och infällt rack obehindrat då remmarna inte kommer i vägen för armarna.

Abstract:

The purposes of this dissertation were to 1) determine what tapering and peaking practices appear to be most effective via systematic review, 2) to identify the tapering and peaking practices used by North American powerlifters, 3) to experimentally compare muscular adaptations and performance changes following two different training cessation periods, and 4) to experimentally compare the two most common taper models following a training program aimed at peaking maximal strength. Based on the scientific literature, a step and exponential taper appeared to be the most effective tapering models used when volume-load is reduced by half over 2±1 week. Interestingly, North American powerlifters reported that the step taper was most often used while reducing volume-load by 41-50% over 7-10 days. Furthermore experimentally, there were no changes in lower body maximal strength following 3 or 5 days of training cessation. However, upper body maximal strength decreased following 5 days of training cessation. Thus, at the end of a taper, a training cessation period of 3 days appears to be effective for maintaining upper and lower body maximal strength. Furthermore, a work-matched step taper and exponential taper produced similar outcomes for 1RM back squat, bench press, and deadlift, powerlifting total and Wilks Score in strength athletes, yet deadlift 1RM changes favored the exponential taper. However, there were clear physiological differences observed at the whole muscle and muscle fiber levels that appeared to contribute to performance outcomes. This was one of the first investigations demonstrating whole muscle and muscle fiber hypertrophy following a peaking program in strength athletes. Immunohistochemical and immunoblotting analyses demonstrated an increase in myosin-heavy chain IIA content with concomitant decreases in myosin-heavy chain I and IIX content, particularly following the step-taper. These myosin isoform shifts towards a faster, higher quality phenotype were related to changes in underlying myocellular signaling (i.e. Sox6 upregulation, micro RNA-499a downregulation) responsible for fiber-type transitions. These findings indicate a shorter taper may produce favorable muscular adaptations followed by a period of short-term training cessation to prevent the loss of taper-induced performance adaptations. Overall, the findings from these investigations support the use of tapering to enhance maximal strength.

Признание специфичности соревновательной двигательной деятельности в пауэрлифтинге не имеет экспериментального подтверждения. Плохо изучена специфика проявления силы в упражнениях силового троеборья у пауэрлифтеров различной квалификации.

Abstract:

The purpose of the study was to determine anthropometric characteristics that may affect deadlift performance. Fourteen powerlifters performed isometric pulls on a force plate at 3 key positions of the deadlift (at the floor, just above the patella, and 5-6 cm short of lockout) and the mid-thigh pull (MTP). RM ANOVA revealed that forces generated at each bar height differed significantly (F(3,39) = 51.058, p<0.05). Discriminant analysis was able to classify lifters into "stronger" and "weaker" groups with 100% accuracy using measured anthropometric dimensions. Stepwise discriminant analysis revealed that height to body mass ratio was important in differentiating performance in all positions but lockout. Segment and various measures of height were also important in discriminating performance in the knee, lockout, and MTP positions. Results of this analysis should provide some insight to the anthropometric dimensions that are related to success in various phases of the deadlift.

Abstract:

Introdução: Atletas de Powerlifting utilizam habitualmente em sua preparação física o Agachamento (AT) e o Box-Squat (BS). Conhecer as variáveis cinemáticas e eletromiográficas destes exercícios é relevante para sua prescrição. Objetivo: Comparar os efeitos agudos da utilização do Agachamento e do Box-Squat, em três diferentes amplitudes de movimento, sobre variáveis de desempenho neuromuscular, em atletas de Powerlifting. Materiais e Métodos: Dez atletas de Powerlifing (31,7±5,05 anos) participaram de duas sessões de avaliação: i) aplicação de questionário, realização de medidas antropométricas e testes de 1RM para Agachamento e Box-Squat nas condições Completo, Paralelo e Parcial; ii) Coleta do sinal eletromiográfico dos músculos Reto Femoral; Vasto Lateral; Vasto Medial; Bíceps Femoral; Glúteo Máximo; Gastrocnêmio Lateral e Eretores da Coluna, durante AT e BS com as cargas de 1RM previamente aferidas. Coleta de dados de cinemetria 2D para o cálculo da Potência Absoluta e Relativa. Resultados: A carga de 1RM (252±55 Kg) e o Índice de Força Relativa (2,66±0,43) do BS Parcial foram significativamente maiores que nas outras cinco variações de exercício. Potência Absoluta (613,25±194,80 W) e Relativa (6,48±1,86) foram maiores no AT Parcial quando comparado a BS Completo, AT Completo, AT Paralelo e BS Paralelo. A ativação EMG do Reto Femoral foi maior no BS Completo (95,48±46,82 %CIVM) comparada à AT Parcial e BS Parcial. O Glúteo Máximo foi mais ativado no AT Paralelo (175,36±101,79 %CIVM) comparado ao BS Completo (143,51±79,00 %CIVM). A ativação dos Eretores da Coluna no AT Paralelo (132,27±77,31 %CIVM) foi superior à do AT Parcial (92,09±38,28 %CIVM). Conclusão: As cargas de 1RM foram maiores em excursões articulares reduzidas, com vantagem do BS Parcial. O AT Parcial apresentou maiores valores de Potência Absoluta e Relativa. AT e BS mostraram-se equivalentes do ponto de vista da ativação muscular. Introduction: Powerlifters commonly use Squats and Box-Squats in their training process. Knowing kinetics and kinematics of these exercises can help trainers when planning a training program. Objective: To compare kinetic and kinematics of full, parallel and partial Squats and Box-Squats performed by Powerlifters. Material and Methods: Ten Powerlifters (31,7±5,05 years) participated in two sessions of data collection: i) Survey about training and injury, Anthropometrical measures, 1RM testing for the full, parallel and partial Squats and Box-Squats; ii) Muscle activity of rectus femoris, vastus lateralis, vastus medialis, biceps femoris, gluteus maximus, lateral gastrocnemius and erector spinae over the six conditions at 100% of 1RM. Sagital plane video was recorded for power output measures. Results: Significantly higher loads were observed in Partial Box-Squat (252±55 Kg) compared to the other five situations. Overall (613,25±194,80 W) and Relative (6,48±1,86) Power Output were higher at Partial Squat when compared to Parallel and Full Squats and Box-Squats. Muscle activation of rectus femoris was significantly higher in Full Box-Squat (95,48±46,82 %MVC) compared to Partial Squats and Box-Squats. Gluteus maximus activation was higher at the Parallel Squat (175,36±101,79 %MVC) when compared to the Full Box-Squat (143,51±79,00 %MVC). Erector Spinae muscle activation was significantly higher in Parallel Squat (132,27±77,31 %MVC) in comparison to the Partial Squat (92,09±38,28 %MVC). Conclusion: Higher 1RM loads were found in Partial Range of Motion, especially in Box-Squat. Overall and Relative Power Output were higher at Partial Squats. Squats and Box-Squats showed similar muscle activation patterns.

Abstract:

Previous attentional focus literature suggests that adopting an external focus (EF) results in greater force production through a variety of mechanisms. The purpose of the present study was to examine the effects of attentional focus and dual-tasking when performing heavily loaded barbell movements that are specific to strength-based sports. Fifteen resistance-trained males (age = 23.3 ± 3.4 years) reported to the laboratory for three visits. The first visit consisted of a five-repetition maximum (5RM) test on the conventional deadlift. During the subsequent sessions, the participants performed a total of twelve single conventional deadlift repetitions while adopting an internal focus (IF), an external focus (EF), or while performing the cognitive task (COG). The IF and EF consisted of focusing on activating the quadriceps and maintain a straight bar path, respectively. The COG consisted of counting the total occurrence of two single-digits in a sequence of three-digit numbers, separately. Three-dimensional motion capture and force platforms were used to collect kinematic and kinetic data. No significant differences were found between the IF, the EF and the COG for lift duration, peak barbell velocity, peak vertical ground reaction force, area of 95% confidence ellipse, peak hip moments and peak hip powers. Adopting an EF significantly reduced variability of the barbell trajectory and centre of pressure (COP) in the anterior-posterior direction. Mean velocity of COP was also significantly lower for the EF. Our findings suggest that adopting an EF may lead to greater postural stability when performing heavily loaded barbell movements.

Abstract:

Fundação de Amparo a Pesquisa do Estado de Minas Gerais Weightlifting first appeared on Paralympics in 1964 in Tokyo, in which the athletes deficiency was exclusively spinal injury. In weightlifting athletes remain lying on a bench, and perform a movement known as bench press. The test begins when the support bar is removed - with or without the help of auxiliary center - leaving the fully extended elbows. The athlete flexing arms, elbows down the bar to the chest. Then the bar is raised to the starting position, ending the movement. The athlete can perform the movement three times, the most validated weight, as referees are aware of the continuous execution of the movement and to clear the bar stop on the chest. The aim of this stud y was to examine kinematic and electromyographic aspects in different periods of the concentric phase of the movement of paralympic bench in high-performance athletes. Participated in three female subjects aged 23 to 48 years (mean 39.8 ± 11.2) and 7 male subjects aged between 18 and 41 years (mean 26.5 ± 8.0) were conducted Attempts to perform 3 to 95% of 1RM load, obeying the rules of the game. They were plotted the velocity curves and offset for later split the concentric phase in phases of pre-sticking, sticking and post-sticking. Electromyography revealed that the deltoid and pectoral muscles had higher recruiting the triceps muscle during much of the concentric phase of the movement. These results suggest that there may have been greater activation of these muscles to compensate for the muscle wasting caused by the eccentric phase O halterofilismo apareceu pela primeira vez em uma Paralimpíada, em 1964, em Tóquio, no qual a deficiência dos atletas era exclusivamente lesão da coluna vertebral. No halterofilismo os atletas perma necem deitados em um banco, e executam um movimento conhecido como supino. A prova começa no momento em que a barra de apoio é retirada com ou sem a ajuda do auxiliar central deixando os cotovelos totalmente estendidos. O atleta flexiona os braços, com os cotovelos descendo a barra até a altura do peito. Em seguida, a barra é elevada até a posição inicial, finalizando o movimento. O atleta pode realizar o movimento três vezes, sendo o maior peso validado, já que os árbitros ficam atentos à execução cont ínua do movimento e a parada nítida da barra no peito. O objetivo do presente estudo foi examinar aspectos cinemáticos e eletromiográficos em diferentes períodos da fase concêntrica do movimento de supino paralímpico em atletas de alto rendimento. Participaram 3 indivíduos do gênero feminino com idade entre 23 e 48 anos (média de 39,8 ± 11,2) e 7 indivíduos do gênero masculino com idade entre 18 e 41 anos (média 26,5 ± 8,0) que foram conduzidos a realizar 3 tentativas a 95% da carga de 1RM, obedecendo as regras da modalidade. Foram plotadas as curvas de velocidade e deslocamento para posteriormente dividir a fase concêntrica em fases de pré-sticking, sticking e póssticking. A eletromiografia revelou que os músculos Deltoide e Peitoral tiveram recrutamento superior ao músculo Tríceps Braquial durante grande parte da fase concêntrica do movimento. Esses resultados sugerem que pode ter havido uma maior ativação desses músculos no sentido de compensar o desgaste muscular causado pela fase excêntrica. Mestre em Ciências

Abstract:

This thesis is a study of how environmental heating affects elite strength and power athletes in resistance exercise sessions. It examines how different combinations of temperature, modes of heating, and different exercises may result in different outcomes in muscular performance, hormone responses, athlete perceptions, and bodily responses. It is shown that intermittent heating at 32 °C may enhance squat exercise outcomes, with important implications for selecting environments to optimise outcomes from a resistance exercise session.

Abstract:

Paralympic athletes (PA) appear to be more prone to chronic overuse injuries from daily wheelchair or crutch use. Over half of these injuries are shoulder related which can deleteriously impact quality of life. Adaptive powerlifters (AP) are a subdivision of Paralympic athletes and are at a higher risk for catastrophic injuries as compared to their counterparts, due to the compound of fatigue and lifting of maximal weights. For this reason, it is vital to have well-designed training plans for these athletes in order to preserve quality of life and maximize performance in competition. Unfortunately, there is a lack of literature on training adaptive athletes for performance. The purpose of this dissertation is to collect and analyze monitoring data of a para-powerlifter preparing for competition over the course of a six-month macrocycle. Specifically, the intention is to 1) explore options in adaptive monitoring measures for the adaptive athlete community via para-powerlifting 2) analyze trends in the training process with such monitoring methods in fatigue and performance and 3) examine efficient and safe training methods and practices for para-powerlifting. The major findings of this dissertation are 1.) Hand grip dynamometry may be a valid monitoring tool used to gain clarity on neuromuscular fatigue within para-powerlifters. 2.) Barbell velocities may reveal trends in fatigue and recovery over the course of a training cycle for para-powerlifters. 3.) Para-powerlifters and para-athletes training for upper-body power development should likely perform bench press using a strap to secure them to the bench for enhanced stability. The significant and consistently increased force outputs the added stability enables the athlete to utilize may bring more pronounced training adaptations towards their goals. This dissertation is exploratory in nature and much more research needs to be done to give the adaptive athlete population adequate information and tools for their long-term success and safety.

Författare: David Fogelström Handledare: Kutte Jönsson Examinator: Tomas Peterson Nyckelord: Styrkelyft, kvinnors upplevelser, hegemoni, hegemonisk maskulinitet, heteronormativitet Syfte: Syftet med det här arbetet är att genom semistrukturerade intervjuer undersöka och förstå kvinnliga styrkelyftares upplevelser av att utöva en traditionellt mansdominerad sport och hur dessa upplevelser kan förstås i relation till hegemonisk maskulinitet. Metod: Genom semistrukturerade intervjuer med kvinnor som tävlar i styrkelyft har jag samlat in och analyserat data för att med denna kunna besvara frågeställningarna. Teori: Den teoretiska utgångspunkten för arbetet är hegemonisk maskulinitetsteori. Resultat och slutsatser: Studien visar att det finns såväl likheter som skillnader mellan styrkelyft och andra mansdominerade sporter i hur kvinnor ser på att utöva en traditionellt mansdominerad sport och deras upplevelser av detta. Exempel på likheter är positiva effekter på självförtroende, viljan att vara förebild och bryta mot könsnormer samtidigt som kvinnor upplevde att de blev ifrågasatta och inte tagna på allvar i samma utsträckning som män. Skillnader var upplevelsen av att inom styrkelyft kunna utmana sig själva och hur tävlandet inom styrkelyft var en stark motivationsfaktor. Author: David Fogelström Supervisor: Kutte Jönsson Examiner: Tomas Peterson Keywords: Powerlifting, women’s experiences, hegemony, hegemonic masculinity, heteronormativity Aim: The purpose of this study is to explore and understand, through semi-structured interviews, female powerlifters experiences of practicing a traditionally male-dominated sport and how these experiences can be understood in relation to hegemonic masculinity. Method: Through semi-structured interviews with women who compete in powerlifting, I have collected and analysed data to be able to answer the questions. Theory: The theoretical framework of this study is Hegemonic Masculinity Theory. Results and Conclusions: The study shows that there are similarities as well as differences between powerlifting and other male-dominated sports in how women experience practicing a traditionally male-dominated sport. Examples of similarities are positive effects on self-confidence, the desire to be a role model and break gender norms while women felt that they were questioned and not taken seriously to the same extent as men. Differences were the experience of being able to challenge themselves in powerlifting and how the competition in powerlifting was a strong motivating factor.

Abstract:

Huvudsyftet med föreliggande studie var att undersöka på vilket sätt coacher inom tyngdlyftning, styrkelyft, Crossfit och kroppsbyggning implementerar preventiva strategier designade för att förebygga skador genom inverkan på psykologiska riskfaktorer. Vidare var det av intresse att undersöka vilka personlighetsdrag hos en idrottare som coacher upplevde ökade risken för skador. Ett ytterligare syfte var att studera coachernas erfarenheter av relationen mellan idrottares stressnivå och skaderisk. Totalt genomfördes nio semistrukturerade intervjuer med coacher på distrikt till internationell nivå lokaliserade i Sverige. Samtliga coacher hade tidigare erfarenhet med skadade idrottare. Resultatet sammanställdes genom en deduktiv innehållsanalys. Under intervjuerna identifierades flera interventionsstrategier som kunde relateras till Williams och Andersens (1998) stressskademodell. Det framgick att coacherna i studien fokuserar mycket på fysiologiska och stressrelaterade aspekter och inte personlighetsdrag när de implementerar interventioner för att förebygga skador. Implikationer för skadeförebyggande träning samt förslag på framtida forskning ges.

Актуальність дослідження зумовлена вирішальним значенням для ефективного фізичного виховання школярів-старшокласників засобами пауерліфтингу в умовах секційних занять. Результати дослідження доповнять теорію і методику фізичного виховання, відповідно до сучасної концепції фізичного виховання, новими положеннями з питань організації фізичного виховання дітей старшого шкільного віку в умовах шкільної секції з пауерліфтингу. Тренувальні завдання спрямовані на удосконалення різних морфо-функціональних структур організму шляхом всебічного розвитку фізичних якостей. Особливо актуального значення цей процес набуває в старшому шкільному віці, який є періодом максимальних темпів природного розвитку практично усіх систем організму школярів і в якому, таким чином, створюються сприятливі біологічні передумови для комплексного вирішення зазначених завдань. The relevance of the study is due to the crucial importance for effective physical education of high school students by means of powerlifting in the conditions of sectional classes. The results of the study will complement the theory and methodology of physical education, in accordance with the modern concept of physical education, new provisions on the organization of physical education of older school children in the school section of powerlifting. Training tasks are aimed at improving various morpho-functional structures of the body through the comprehensive development of physical qualities. This process is especially important in senior school age, which is the period of maximum rate of natural development of almost all body systems of students and which, thus, creates favorable biological conditions for a comprehensive solution to these problems.

Abstract:

Objectives: To determine if force differences exist between isometric pulling positions corresponding to key positions of the deadlift. Design: Cross-sectional evaluation of isometric strength Methods: 14 powerlifters performed isometric pulls on a force plate at 3 key positions related to the deadlift (at the floor, just above the patella, and 5-6 cm short of lockout) and in the mid thigh pull position (MTP). A 1x4 repeated measures ANOVA was used to ascertain differences between the various pulling positions tested. Bonferroni-adjusted paired samples t-tests were used post-hoc. Results: Forces generated at each bar height were significantly different (F(3,39) = 51.058, p2=0.80). Paired samples t-tests showed significant differences between positions, revealing a trend of greater force generation at increasing heights for positions corresponding to the deadlift. Force generated in the mid thigh pull position was significantly higher than any other position. Conclusion: In positions corresponding to the deadlift, force generation increases at higher bar heights.

Consequently, advances in assessment and training methods have emerged. However, the paralympic sport keeps in tow these advances, with few specific studies that consider disability as intervening factor. The transcranial direct current stimulation (tDCS) is a technique that has proven to be capable of modulating brain function. Studies show beneficial effects of tDCS on muscle strength, power and fatigue during exercise. Objective: Investigate de the effect of tDCS on movement control in para-powerlifters. Methods: Eight subjects underwent two sessions of motion capture, which previously applied the anodic tDCS or sham sessions in the cerebellum. Three movements were performed with increasing load between 90-95% of 1MR. The movements were recorded by an 10 infrared cameras system which reconstructed the 3D trajectory of markers placed on the bar. Results: There have been changes between the anodic and sham conditions over bar level (initial, final, maximum during the eccentric and concentric phase) and in the difference between the final and initial bar level. Moreover, there was difference in bar level (final and during the eccentric phase) comparing athletes amputees and les autres. Conclusion: The findings of this study suggest that tDCS applied prior to the exercise over the cerebellum in para-powerlifters acts differently according to disability Introdu??o: O esporte praticado por pessoas com defici?ncia vem crescendo nos ?ltimos anos. Consequentemente, avan?os nos m?todos de avalia??o e treinamento t?m surgido. Por?m, o esporte paral?mpico segue a reboque destes avan?os, com poucos estudos espec?ficos que considerem a defici?ncia como fator interveniente. A estimula??o transcraniana por corrente cont?nua (ETCC) ? uma t?cnica que vem se mostrando capaz de modular a fun??o cerebral. Estudos mostram efeitos ben?ficos da ETCC sobre a for?a muscular, fadiga e pot?ncia durante exerc?cio. Objetivo: Investigar o efeito da ETCC sobre o controle do movimento em para-halterofilistas. Metodologia: Oito sujeitos foram submetidos a duas sess?es de captura de movimentos, sendo aplicado previamente as sess?es ETCC an?dica ou sham no cerebelo. Foram realizados tr?s movimentos com carga crescente entre 90-95% de 1RM.

Abstract:

Creatine is nitrogen-containing organic acid which naturally occurs in the human body. The aim of this work was to determine the optimal dose of creatine in combination with vitamin C and magnesium for male respondents aged 18-26 years. They were divided into two groups differing in the creatine dosage. Group 1 took smaller dose of creatine (3 g per day) and group 2 higher dose of creatine (10 g per day). Both groups took both magnesium and vitamin C at constant doses throughout the study. The effects of significantly different dose of creatine in the individual groups were compared with each other in terms of the performance of individuals in the powerlifting, the anthropological changes and the overal metabolism of the intakes. In all disciplines of powerlifting, group 1 recorded higher average weight gains, which were not found to be statistically significant at a significance level of alpha 0,05. Anthropological changes were measured using the InBody 160 and a diagnostic measuring tape. In both cases, group 1 recorded better results than group 2, but these results were not statistically significant at a significance level of alpha 0,05. The total metabolism of the accepted dietary supplements was investigated through analytical methods. The urine of each respondent was regularly collected and subsequently analyzed during the research. Determination of creatinine, a creatine waste product, was performed by UV-VIS spectrophotometry using the Jaffe reaction. Vitamin C was analyzed by RP-HPLC. Magnesium was determined by the ICP-OES method. After creatine suplemantion of 3 per day, group 1 showed a slight increase in creatinine in the urine, but still in the physiological range. At the significance level alpha 0,05 there was no statistically significant difference. Group 2 showed an increase above the physiological limit which was already a statistically significant difference. Overall, creatine supplementation of 3 g per day has been found as a sufficient intake of creatine needed to build up muscle mass, increase energy metabolism and overall physical performance. The metabolization itself works very well and within the physiological values.

Abstract:

碩士 國立政治大學 國際經營管理英語碩士學位學程(IMBA) 107 The fitness industry has been having many happy years. Clubs across the world are constantly opening up and the number of gyms and options available have never been greater. No longer are people stuck with basic gyms that lack direction and don’t fulfill their desires. Nowadays, there are almost too many choices and people have to choose what is best for them at the time, as life and wants change. And often that choice changes due to many factors. However, there is one common theme that is at play: more gyms are opening and more people are going. People usually cite health as the number one reason they do so. Whether it be because they are more educated about the need for exercise or because they simply enjoy the challenges; it doesn’t matter, gyms are needed to match their needs. And the needs are drastically changing. No longer are simple gyms with machines and weights cutting it. The two types of gyms that have found the greatest growth, according to the 2018 Piper Jaffrey Report, are HVLP (High Volume Low Price) and Boutique Gyms. They vastly differ on price. The HLVP segment is a very inexpensive gym that may charge as low as $300nt/month, whereas the boutique gyms are more expensive, maybe $6000nt/month, and joining a group class can cost $1000nt/session. However, what really stands out is that the boutique gyms can vary considerably in what they offer. Choices range from boxing, yoga, cycling, cross fit, among many others. Of all the types out there, one that doesn’t have a large following, but is popular, is powerlifting gyms. These gyms are growing in popularity in the U.S., partly due to awareness, personal trainers, and specialized classes. This is where the business plan for Strength Central comes in. There is no other gym in New Taipei or Taipei that focuses purely on power and strength. By developing a new business that doesn’t exist yet we hope to create a new culture of strength training in Taiwan. Strength Central is a gym designed to teach and educate gym goers how to become strong while doing so safely. The gym is designed to allow for 20 people to be doing lifts at one time. It not only has a great environment, but also has the perfect equipment for doing the key lifts. Strength Central is a gym designed to meet the needs of those that have an inner drive for pure strength. Members are after the challenge for lifting more weight and hitting new goals, then setting new goals, and repeating. It’s almost like training for the Olympics. Everyone is trying to do the most that they can in one single, powerful movement. Strength Central is a gym planned for people to train in one of the five (or so) weightlifting movements. Most gyms are not designed for people to train as such. Even popular gyms, like World Gym in Taiwan, only offers 3-5 stations for people to train in heavy lifting. Then there are other gyms that have some of the tools but lack the culture of a true powerlifting gym. A true powerlifting gym needs the right environment, training, classes, equipment, and people in order for all to thrive. With a gym that has a more focused goal, powerlifting, Strength Central can also be successful in Taiwan because we are one of the first movers. Thus, Strength Central can safely improve the health and strength of its members.

Abstract:

Powerlifters utilise a unique breathing pattern known as the Valsalva manoeuvre (VM) in order to help them move maximal loads. This pattern of breathing is thought to impact a powerlifter’s cardiac morphology; however, the functional consequences of this are still unknown. The VM has profound implications for the cardiovascular system, with heart rate and blood pressure demonstrating four phases of reciprocal behaviour. This study proposed that there may be observable differences in the cardiovascular response to the VM when comparing powerlifters to those who are Valsalva-naïve. It was also speculated that changes in the expiratory pressure of the VM may influence the cardiovascular response. The final question was whether any of the differences observed were dependent on sex. This study found that there were statistically significant differences in the heart rate and blood pressure response exhibited by powerlifters when compared to sedentary controls. For instance, the blood pressure change in Phase I of the VM was 28mmHg in powerlifters compared to 15mmHg in sedentary (p <0.05). There were also significant differences in the cardiovascular response of all participants when performing the VM at varying intensities of expiratory pressure. For example, the VM Phase II heart rate changed by 40 ± 25 beats.min-1 during a protocol at fifty percent of maximum expiratory pressure, which was significantly (p <0.05) greater than the heart rate change observed during the protocol at thirty percent of maximum expiratory pressure (25 ± 14 beats.min-1). However, none of the differences observed which resulted from training status or intensity were dependent on sex. The findings of this study suggest that within the VM’s inherent cardiovascular pattern, heart rate and blood pressure respond to training and intensity in a way that is similar to other contexts of isometric exercise. This thesis contributes to the understanding of cardiovascular functional differences in powerlifters. This thesis also provides new insight into VM methodology, which may be applicable to other settings of VM utilisation. Finally, this work provides knowledge about female physiology in exercise science, an area which is currently lacking.

碩士 國立臺灣體育學院 體育研究所 98 Through the blossom of economy, there are more and more people willing to participate in powerlifting. Since 1988, Taiwan powerlifting has been internationalized and the athletes have created excellent achievements year by year.1997 is the remarkable year to Taiwan powerlifting, the results of women and men light-weighting were outstanding as well as the top powerlifting athletes of the globe. Since then, Taiwan powerlifting has been earning its reputation in the world. 　　The main purpose of the study is to explore the process of development of powerlifting in Taiwan. In-depth interviews and literature reviews are implemented in the study. In order to understand the development and transition of powerlifting in Taiwan, the documents organized by time period are as follows: 1.Germination era (1975~1987): Originally, powerlifting was one of the weightlifting events, however, it was organized individually through efforts from the enthusiatic sportsperson. 2.Hard-working era (1988~1999): Through a lot of diffulties, Chinese Taipei Powerlifting Association finally had its own name. 3.Prosperous era (2000~2008): Powerlifting had made efforts for over one decade, its athletes benefited by the support of the authorities concerned. The researcher hopes powerlifting could be popularized to junior and senior high school studnets in order to develop more outstanding athletes. 　　Finally, the researcher came up with some suggestions for authorities concerned to improve the drawbacks and for future researchers to refer to. We hope powerlifting could be sustainable and have a prospective future.

Abstract:

Dissertação de mestrado em Psicologia da Educação, Aconselhamento e Promoção do Desenvolvimento, apresentada à Faculdade de Psicologia e Ciências da Educação da Universidade de Coimbra Podemos ver o desporto como um local priorizado para observar e analisar o comportamento humano num ambiente natural. É um contexto que realça, para além de outras emoções, a ansiedade, influenciando deste modo o rendimento desportivo. O presente estudo pretende por isso compreender e definir o perfil dos atletas de powerlifting tendo em conta os fatores de predisposição à prática da modalidade, a relevância deste desporto nas suas vidas, a forma como respondem às situações problemáticas, o modo como se percecionam e a preocupação com a imagem corporal. Neste sentido, foram utilizados pressupostos da Grounded Theory (Glaser & Satruss 1967; Charmaz, 1995; Strauss & Corbin, 1990, 1998) em que a recolha de dados aos atletas da modalidade Powerlifting (N=12) da Associação Académica de Coimbra, foi elaborada, em contexto de domicílio e ginásio, através de entrevistas semi estruturadas e utilizando o inventário de Autoestima de Rosenberg (1965), o Big Five Inventory de John Oliver et al (1991) e o PANAS de Watson, Clark e Tellegen (1988). Estes últimos não com o propósito de avaliar exatamente as 3 dimensões correspondentes aos mesmos, mas sim de completar a informação recolhida nas entrevistas. Da análise elaborada surgiram cinco extensões relacionadas e interdependentes - Competição, Corpo, Formas de agir, Treino e Importância do Powerlifting - algumas delas estendendo-se a várias categorias. O modo como foi interpretado o resultado advém de frases e expressões relatadas pelos sujeitos, despoletando deste modo um alargado conjunto de fatores de análise, influenciados por variáveis biopsicossociais. Os testemunhos, para além da subjetividade que os carateriza, apresentam relatos bastante idênticos, salvo algumas exceções, convergindo num padrão que nos permite conhecer mais afincadamente os atletas em questão e as suas motivações. Os resultados desta dissertação poderão ajudar a que conheçamos melhor os propósitos, os objetivos, as formas de agir, as motivações, os sentimentos, as metas, os dilemas, a dedicação e características de personalidade o que, de certo modo, lhes confere uma identidade muito particular. We can see sports as a privileged activity where we can observe and analyse the human behaviour within its natural environment. Besides another emotions, sports are a context that emphasizes anxiety which directly influences the performance of the athletes. Therefore, this study intends to understand and define the profile of Powerlifting athletes, regarding some factors, such as, their predisposition to the engagement in this type of sports, the relevance of this sport in their lives, the way in which the athletes respond to problematic situations, the way athletes perceive themselves and their concerning about their corporal image. To reach this, we used the assumptions of the Grounded Theory (Glaser & Satruss 1967; Charmaz, 1995; Strauss & Corbin, 1990, 1998), where we captured data from the Powerlifting athletes (N=12) of Associação Académica de Coimbra, in both contexts of home and gymnasium, through semi-structured interviews and employing the Self-Esteem inventory of Rosenberg (1965), the Big Five Inventory of John Oliver et al (1991) and the PANAS of Watson, Clark and Tellegen. These last two were not utilized with the objective of evaluating the 3 dimension that correspond to themselves, but to complete the information captured in the interviews. From the elaborated analysis, five extension came out related and interdependent- Competition, Body, acting ways, training and the Porwerlifting importance- where some of them extended themselves to several categories. The way that the result was interpreted comes from the sentences and the pattern expressions made by the study subjects, giving a broad set of analyses factors, influenced by biopsychicosocial variables. Besides the subjectivity of the subjects, the testimonies are really identical, where some exceptions may be applied. This converges into a pattern that allows us to know the athletes better and their motivations, as well. The results of this dissertation may help us to know the Powerlifting athletes, with their purposes, objectives, acting ways, motivations, feeling, dilemma, dedication and certain personality traits that are so inherent to these athletes, conferring an identity that only belongs to them.

Abstract:

碩士 中國文化大學 體育學系運動教練碩博士班 107 Powerlifting is a particular sport pursuing the maximum strength in three exercises as follows Squat, Deadlift and Bench press. Currently, the Powerlifting applied in multiple facets, and athletes or the general population could benefit effectively. The concept of Periodization has been proved to be one of the most efficient and scientific training methods until now; however, there is still ambiguous on how to choose the optimal training model for the powerlifting. Hence, this study applied practical intervention to compare the difference between different periodization models. Purpose: It compared the effects of Linear Model (LM) and Conjugate Model (CM) on Powerlifting performance in eight-week training. Method: Seventeen healthy male students with more than one-year strength training experiences were recruited as subjects. The training program was assigned into three days individually; meanwhile, each subject accepted the maximal strength test in three core exercises and the 10 RM test in assisted exercises before and after 8-week training. The statistical method adopted two-way ANOVA, mixed design to investigate the trends in two different training models. Result: Both groups showed a significant improvement after training (F=155.574, p=.000). In the aspect of progress, the LM in deadlift (F=17.96, p=.001<0.05) and the total volume (F=4.81, p=.044<0.05) were significantly better than the CM. Moreover, the training volume was significantly higher in the CM than LM in the eighth week (F=162.305, p=.000<0.05). There was no significant difference between two groups in the degree of exhaustion, but the CM showed minor tendency. Conclusion: Both periodization models may improve the Powerlifting performance, but the LM seems to be more beneficial for primary and intermediate level powerlifters.

Abstract:

Este trabalho foi expressamente elaborado como dissertação original para efeitos de obtenção do grau de Mestre em Ciências do Desporto O interesse pelos esportes paralímpicos tem crescido, contudo, as pesquisas sobre o Powerlifting Paralímpico têm sido voltadas para a origem de possíveis lesões e critérios de classificação, tendo o desempenho levado pouca consideração. Desta forma, este estudo teve como objetivo avaliar a eficiência de diferentes tipos de aquecimento (sem aquecimento, aquecimento tradicional e com alongamento) sobre o desempenho de atletas do Powerlifting Paralímpico. A amostra contou com 12 atletas do sexo masculino praticantes de Powerlifintng Paralímpico (PP). O estudo foi realizado em três semanas, sendo a primeira semana destinada a familiarização do protocolo de testes de 1RM (dia 1); teste de Força Isométrica Máxima (FIM) com a Barra a 15 cm do Peito, Taxa de Desenvolvimento de Força (TDF), Índice de Fadiga (IF), Tempo até a Força Máxima (Tempo) (dia 2); e Velocidade Máxima (VMax) (dia 3). A semana 2, foi destinada aos testes de 1RM e de Velocidade Máxima (VMax). A semana 3 foi destinada a avaliação das variáveis estáticas da força. Nas semanas 2 e 3 os indivíduos foram direcionados aos testes a partir de três formas diferentes de aquecimento (Sem Aquecimento, Aquecimento Tradicional ou Aquecimento através de Alongamento), sendo a ordem determinada através de sorteio, onde 1/3 dos sujeitos de cada grupo fizeram cada tipo de aquecimento em uma das sessões de avaliação. Como principais resultados verificou-se que em relação a temperatura timpânica foram encontradas diferenças significativas entre o Sem Aquecimento Antes (SA) (36.52±0.21ºC, IC 95% 36.39-36.66) e o Alongamento Antes (AA) (36.43±0.16ºC, IC 95% 36.32-36.53), com p=0.006. Houve diferença entre o SA e o Sem Aquecimento 10 Minutos depois (S10) (36.40±0.10ºC, IC 95% 36.33-36.47), p=0.026. Também foram encontradas diferenças entre o Aquecimento Tradicional Antes (TA) (36.47±0.16ºC, IC 95% 36.37-36.57), e o Tradicional Depois (TD) (36.58±0.19ºC, IC 95% 36.46-36.70), p=0.007 e em relação ao Tradicional 10 Minutos depois (T10) (36.62±0.11ºC, IC 95% 36.55-36.69), p=0.002. Houve diferenças entre o AA e o Aquecimento com Alongamento Depois (AD) (36.55±0.19ºC, IC 95% 36.43-36.67), p<0.001. Foi encontrada diferenças entre o Sem Aquecimento Depois (SD) (36.47±0.12ºC, IC 95% 36.39-36.54) e o TD, p=0.007, e em relação ao AD, p=0.031. Houve diferenças entre o SD e o AS, p=0.002. Também foi encontrada diferença entre o Alongamento 10 Minutos depois (A10) (36.51±0.16 ºC, IC 95% 36.41-36.61) e o T10, p<0.001. Já para a TDF, FIM, IF e Tempo foram encontradas diferenças significativas entre o aquecimento com alongamento e sem aquecimento (p=0.005) em relação a FIM. Não houve diferenças significativas na TDF, IF e Tempo até FIM nos diversos tipos de aquecimento, como também não foram encontradas diferenças significativas em relação a Repetição Máxima (p=0.121, ɳp 2=0.275, Efeito Médio) e nem em relação a Velocidade Máxima (p=0.712, ɳp 2=0.033, Efeito Baixo), entre os diversos tipos de aquecimento. Diante dos resultados concluiu-se que o tipo de aquecimento parece não interferir na manifestação da força, podendo ficar a critério de cada atleta o tipo de aquecimento que melhor ele se adapte, ou ainda há a possibilidade de não fazer aquecimento algum e também obter um resultado positivo. Interest in Paralympics sports has increased; however, researches on Paralympic Powerlifting has been focused on the origin of possible injuries and classification criteria, while little attention has been given to athletes’ performance. Thus, this study aimed to evaluate the efficiency of different types of warm-up (No Warm-up, Traditional Warm-up, and With Stretching) on Paralympic Powerlifting athletes’ performance. The sample considered 12 male Paralympic Powerlifting (PP) athletes. This study was developed throughout three weeks, considering that the first week was scheduled for the athletes to be familiarized with the patterns of testing one-repetition maximum (1RM) (1st day); Maximum Isometric Strength (FIM) testing with the bar 15cm far from the athletes’ chest level, Strength Development Rate (TDF), Fatigue Index (IF), Time until the Maximum Strength (Time) (2nd day); and Maximum Speed (VMax) (3rd day). The 2nd week was scheduled for 1RM and Maximum Speed (VMax) tests. The 3rd week was scheduled for the strength static variables evaluation. In the 2 nd and third weeks, the participants were directed to the tests considering three different kinds of warm-up (No warm-up, Traditional warm-up, or Warm-up through Stretching). The sequence of tests was determined by a raffle, which 1/3 of the participants in each group did each type of warm-up in one of the assessment sections. As the main results, related to tympanic temperature, significant differences were found between No Warm-up Before (SA) (36.52±0.21ºC, IC 95% 36.39-36.66) and Stretching Before (AA) (36.43±0.16ºC, IC 95% 36.32-36.53), p=0.006. There was a difference between SA and No Warm-up 10 minutes later (S10) (36.40±0.1ºC, IC 95% 36.33-36.47), p=0.026. Differences were also found between Traditional Warm-up Before (TA) (36.47±0.16ºC, IC 95% 36.37-36.57), and After Traditional (TD) (36.58±0.19ºC, IC 95% 36.46-36.70), p=0.007 and related to the Traditional 10 minutes later (T10) (36.62±0.11ºC, IC 95% 36.55- 36.69), p=0.002. There were differences between AA and Warm-up with After Stretching (AD) (36.55±0.19ºC, IC 95% 36.43-36.67), p<0.001. Differences were found between No After Warm-up (SD) (36.47±0.12ºC, IC 95% 36.39- 36.54) and TD, p=0.007, and related to AD, p=0.031. There were differences between SD and AS, p=0.002. In addition, there were also differences between Stretching 10 minutes later (A10) (36.51±0.16ºC, IC 95% 36.41-36.61) and T10, p<0.001. Considering TDF, FIM, IF, and Time, significant differences were found between Warm-up with Stretching and No Warm-up (p=0.005) related to Maximum Isometric Strength (FIM). There were no significant differences on Strength Development Rate, Fatigue Index and Time until the FIM, on different kinds of warm-up, as well as no relevant differences were found neither related to Maximum Repetition (p=0.121, ɳp 2=0.275, Medium Effect) nor related to Maximum Speed (p=0.712, ɳp 2=0.033, Low Effect), among different kinds of warm-up. By the results, it was concluded that the kind of warm-up seems not interfering with the strength demonstration, therefore, it is at the athletes’ discretion deciding on the best kind of warm-up for them, or there is the possibility of doing no kind of warm-up and still getting a positive result.

Abstract:

Dissertação de Mestrado em Biocinética apresentada à Faculdade de Ciências do Desporto e Educação Física O treino de força máxima (MST) é caracterizado pela manipulação de resistênciasexternas de grande magnitude (75% a 90% da 1RM). A prescrição do treino de MST énormalmente estruturada para aplicação em treino intervalado, organizado em séries derepetições de exercícios. Para este tipo de força, a literatura sugere que longos tempos derepouso que assegurem uma recuperação completa entre cada conjunto de repetições(série), contribuem para otimizar o processo de treino (Ellers et al., 2016). O objetivodeste estudo foi verificar a relação entre a saturação de oxigénio muscular (SmO₂) nomúsculo vasto lateral e o intervalo de repouso com recurso à análise do desempenho numprotocolo de treino com o objetivo de melhorar a capacidade de produção de forçamáxima no movimento back squat. Seis sujeitos do sexo masculinos com experiência erecente frequência de prática de powerlifting (média ± DP: idade, 24,1 ± 2,68 anos;estatura, 147 ±71,4 cm; massa corporal, 83,9 ± 8,93 kg) participaram na presenteexperiência. Esta foi dividida em dois momentos, onde foram realizadas duas simulaçõesde um treino orientado para a melhoria da capacidade de produção de força máxima (5séries de 3 repetições a 83%). No primeiro momento (PT1) os tempos de recuperaçãoentre séries foram cronometrados num tempo fixo de oito minutos. Já o segundo momento(PT2), utiliza dados recolhidos durante o PT1 e a posterior análise individual, paraidentificar o tempo médio para atingir valores ótimos de reoxigenação do tecido muscular(time delay), que foram tidos como referência para o controle dos tempos de descansoentre séries em PT2.Os resultados sugerem que a diminuição dos tempos de recuperação definida pelosvalores obtidos de Time delay em PT1, não tiveram um significativo impacto naperformance quando comparamos o rendimento da amostra entre PT1 e PT2. O que nosleva a concluir que os períodos de recuperação definidos para PT2 permitiramrecuperações completas, evitando um acúmulo de fadiga exponencial que pudesse afetarnegativamente a performance da amostra. Maximum strength training (MST) is based on the manipulation of externalresistances of great magnitude (75% to 90% of the 1RM). The MST training prescriptionis usually structured by interval training, organized in set of na exercise repetitions. Forthis type of effort, the literature suggests that long rest times that ensure a completerecovery between each sets optimize the training process (Ellers et al., 2016).The aim ofthis study was to verify the relationship between muscle oxygen saturation (SmO₂) in thevastus lateralis muscle and the rest interval using the performance analysis over a trainingprotocol with the goal of improving maximal force capacity in the back squat exercise.Six male subjects with experience and recent frequency of powerlifting practice (mean ±SD: age, 24.1 ± 2.68 years; height, 147 ±71.4 cm; body mass, 83.9 ± 8.93 kg) participatedin the present experience. This one, was divided into two moments, where twosimulations of a training aimed at improving the capacity to produce maximum strengthwere performed (5 sets of 3 repetitions at 83%). In the first moment (PT1) the subjects,recovery times between sets were timed in eight minutes. The second moment (PT2) usescollected data during PT1 and individual analysis, to identify the average time to reachoptimal values of reoxygenation in muscle tissue (time delay), which were taken as areference to control rest times between sets in PT2.The results suggest that the decrease in recovery times defined by the Time delayvalues from PT1 did not haved a significant impact on performance when comparing thesample throughput moments. Our findigns lead us to conclude that the recovery periodsdefined for PT2 allowed for complete recoveries, avoiding an exponential accumulationof fatigue that could had a negative impact on performance

Abstract:

Orientação: Susana Maria Mariano dos Santos Veloso Atualmente, em Portugal, assiste-se a um aumento de praticantes das modalidades de halterofilismo e powerlifting que não parecem ser acompanhadas pelo desenvolvimento de investigação científica que suporte as boas práticas de treino e acompanhamento destes atletas. A ansiedade no desporto parece atingir muitos destes atletas, face à constante pressão psicológica que o treino e competição lhes coloca. O mindfulness, conhecido como a capacidade de autorregular atenção no momento presente, com uma atitude de aceitação e de não-julgamento à experiencia que emerge (Kabat-Zinn, 1994), é outra variável reconhecida no alívio do stress que tem vindo a ser aplicada no treino mental de alta competição, permitindo a autoregulação dos estados psicológicos internos dos atletas. Esta investigação, parte da caracterização destas duas modalidades, com o objectivo principal de analisar a relação entre a capacidade de mindfulness e a ansiedade desportiva em atletas de halterofilismo e powerlifting. Procurou-se ainda compreender o modo com estas variáveis se relacionam com o desempenho dos atletas, e explorar a relação com o género, modalidade e nível competitivo. A amostra foi constituída por 60 atletas portugueses de alta competição, 35 de halterofilismo e 25 de powerlifting, sendo 31 do sexo feminino (51,7%) e 29 do sexo masculino (48,3%), com idades compreendidas entre os 16 e os 70 (M=37,32; DP=12,47), que participaram numa competição nacional em Julho de 2019. A ansiedade foi medida pelo Sport Anxiety Scale (SAS) e o mindfulness foi avaliado pelo Philadelphia Mindfulness Scale (PHLMS). Os resultados mostraram a ausência de correlação entre a ansiedade no desporto e o mindfulness, mas ambas de correlacionam com o desempenho. Encontraram-se resultados nas diferenças entre atletas com maior e menor nível competitivo, sendo que os primeiros mostraram uma maior a capacidade de mindfulness, uma menor ansiedade desportiva, e ainda uma perceção do desempenho maior do que os segundos. Conclui-se que o desempenho destes atletas se correlaciona com uma menor ansiedade, e tende a ser influenciado por uma maior capacidade de mindfulness. Neste sentido o treino psicológico focado na prática de mindfulness poderá contribuir para incrementar o rendimento desportivo nestas modalidades. Currently, in Portugal, there is an increase in weightlifting prectitioners that don’t seem to be accompained by the scientific reaserch’s development, wich supports the good training habits and that properly accompany the athletes.Anxiety in sport seems to affect many of these athletes, given the constant psychological pressure that training and competition puts on them. Mindfulness, known as the ability to self-regulate attention in the present moment, with an attitude of acceptance and non-judgment to the experience that emerges (Kabat-Zinn, 1994), is another variable recognized in the relief of stress that has been applied in high competition mental training, allowing the self-regulation of athletes' internal psychological states. This research is based on the characterization of these two modalities, with the main objective of analysing the relationship between the capacity of mindfulness and sports anxiety in weightlifting and powerlifting athletes. We also tried to understand how these variables are related to the performance of the athletes, and to explore the relationship with gender, modality and competitive level. The sample consisted of 60 Portuguese top-level athletes, 35 weightlifting and 25 powerlifting, 31 female (51.7%) and 29 male (48.3%), aged between 16 and 70 (M=37.32; DP=12.47), who participated in a national competition in July 2019. Anxiety was measured by the Sport Anxiety Scale (SAS) and mindfulness was assessed by the Philadelphia Mindfulness Scale (PHLMS). The results showed no correlation between anxiety in sport and mindfulness, but both correlated with performance. Results were found in the differences between athletes with higher and lower competitive levels, with the former showing higher mindfulness capacity, lower sports anxiety, and also a higher perception of performance than the latter. It is concluded that the performance of these athletes is correlated with less anxiety, and tends to be influenced by a greater capacity of mindfulness. In this sense the psychological training focused on the practice of mindfulness may contribute to increase the sports performance in these modalities.

Abstract:

The purpose of this study is to contribute to the literature on successful aging, serious leisure, and sport. A qualitative methodology was used to understand the lived experiences of three master-aged athletes involved in serious powerlifting. The goal of using such an approach was to share participants’ stories within a given context, as well as uphold the emotion, merit, and authenticity of each narrative. The results address issues around participants’ initial and continued engagement with the sport of powerlifting, the ways in which powerlifting shapes the aging process, and the meaningful role that powerlifting plays in one’s life. The discussion offers further exploration of key points, including: reconnecting to one’s youth, modified training and pain management, identity formation, resistance toward older female powerlifters, powerlifting as a context for self-improvement, career stages over the life-course, social interactions and relationships, and aging successfully. A number of future research directions are offered in the hope of continuing to understand the experiences of older adults in the context of physical activity. Graduate 0680 absilver@uvic.ca
