Full textAffective responses to physical exercise have been reported as predictors of the degree of engagement a personis ready to set in regular practice (Mohiyeddini, Pauli, & Bauer, 2009). According to the dual mode theory, theindividuals’ differences occurring during the exercise are due to the interplay between one’s physical abilitiesand one’s psychological characteristics (Ekkekakis, 2003) with some experiencing positively the session whileothers do not (Van Landuyt, Ekkekakis, Hall, & Petruzzello, 2000). Hence, my thesis work targeted the betterunderstanding of the effect of one of the psychological characteristics, the Tolerance to effort, on one’saffective responses during moderate physical exercise. Furthermore, I tried to reveal that a neuropsychologicaldefinition of the Tolerance to effort can be possible, even required for prescribing exercise program. Toleranceis defined as a trait that influences one’s ability to continue exercising at an imposed level of intensity even ifthe activity becomes uncomfortable or unpleasant (Ekkekakis, Hall, & Petruzzello, 2005). To date, my workhas revealed that the concept of Tolerance seems to be a valid concept in a French-speaking European sample(Study I). Interestingly, the results were revealed whatever the individuals’ self-reported weekly physicalpractice. My work also shows that the way one experiences a physical exercise depends on one’s tolerancelevel (Studies II and IV). Furthermore, the more individuals were tolerant to effort, the more they were able toproduce intense physical exercise (Studies III and IV). Interestingly, results revealed that one’s tolerance levelseems to be associated with one’s efficiency of cognitive functioning. More specifically, the more individualspossess efficient executive functions, the more they possess high level of Tolerance to effort (Study III).Finally, the positive effect of a musical distracting environment on one’s perception of physical exercisedifficulty was revealed only in high tolerant individuals (Study IV); suggesting that music may not be adaptedto all. To conclude, through the conduction of a psychometric assessment of the French-speaking version(Study I), a dual task paradigm (Study II) and a neuropsychological assessment of individuals cognitiveabilities (Study III), my thesis work has revealed that one’s tolerance level seems to be a French-speaking validconcept predicting the positive or negative affective response to physical exercise either in silence or in music(Studies II and IV) and defining one’s tolerance to effort from a cognitive standpoint

Background and Aim: The power-duration relationship accurately predicts exercise tolerance for constant power exercise performed in the severe intensity domain. At intensities above critical power (CP), the power-duration relationship establishes a hyperbolic curve. However, the prediction of exercise tolerance is currently unclear for work rates within the extreme intensity domain (durations <2min). We hypothesized that the power-duration relationship deviates from a linear 1/time relationship for WRs within the extreme intensity domain. Methods: Six men completed nine bilateral knee-extension tests on non-consecutive days and then performed 3 exercise tests in the severe intensity domain (S1-S3; T[subscript lim]>2–15min) and 4 in the extreme domain at 60%, 70%, 80%, and 90%1RM (T[subscript lim]<2min), in random order. Twitch force (Q[subscript tw]), maximal voluntary contraction (MVC), and voluntary activation (VA) were measured on the right vastus lateralis before and after <80s) each test; EMG was measured on the right vastus lateralis throughout each test. T[subscript lim] were plotted as a function of 1/Time. T[subscript lim] for the extreme intensities were compared to the predicted T[subscript lim] of the slope of the S1-S3 regression. Results: The r² for the severe domain 1/time model was 0.99 ± 0.007. T[subscript lim] for exercise at 60%1RM was not different than the predicted T¬lim, however, T¬lim for exercise at 70–90%1RM was shorter than the predicted T[subscript lim] (p<0.05). Post hoc analysis of the extreme domain (70–90%1RM) revealed a significant linear relationship, suggesting a W’ within the extreme domain (W’ext). T[subscript lim] of exercise at 60% 1RM was not different from the predicted value of the 1/Time relationship of the extreme domain. Q[subscript tw] and MVC were significantly decreased following exercise at S1-S3 and 60% 1RM, while no changes existed in Q[subscript tw] or MVC following exercise at 80 and 90%1RM. Further, no changes were found in VA following any exercise intensity. Conclusion: These data suggest that exercise tolerance in the extreme domain is limited by different factors than in the severe domain. However, there is a separate but measurable W’ext. Further, the factors limiting exercise in the extreme domain must be those from can be recovered by the time post-exercise measurements were made.

Em razão de, em estudos que analisam a relação remodelação cardíaca e estenose aórtica supravalvar: ser importante a detecção precoce da disfunção ventricular; o método hemodinâmico ser ideal para detecção da disfunção, porém inadequado para estudos seqüenciais; a taquipnéia manifestar-se, geralmente, quando há deterioração cardíaca grave e não estar estabelecida a relação entre a capacidade funcional e a função ventricular, torna-se necessário identificar se o(s) primeiro(s) sinal(is) de intolerância ao esforço físico está(ão) relacionado(s) a disfunção ventricular. Assim, este trabalho tem como objetivos avaliar em diferentes períodos, 3, 6, 12 e 18 semanas, após indução de estenose aórtica supravalvar em ratos a: 1) função do ventrículo esquerdo em repouso e as alterações morfológicas cardíacas por meio do ecocardiograma; 2) tolerância ao esforço físico, em teste incremental em esteira; 3) relação entre a tolerância ao esforço físico e a função cardíaca determinada em repouso. Foram utilizados 37 ratos Wistar, jovens, machos divididos em dois grupos: controle operado (GC, n=13) e estenose aórtica supravalvar (GEAo, n=24). O GEAo foi submetido a cirurgia com implantação de um clipe na artéria aorta para a indução da estenose aórtica supravalvar. O GC foi submetido à mesma cirurgia, porém sem a implantação do clipe. Os animais foram mantidos com água e ração e ad libitum, em ambiente com temperatura controlada a 23°C e ciclo de luz invertido. Todos os procedimentos foram realizados no ciclo escuro, com o auxílio de iluminação fluorescente vermelha, cuja emissão de onda, por ser longa, não é percebida pelos animais. Dos 24 ratos do grupo estenose aórtica (GEAo), 10 morreram e dois apresentaram sinais de insuficiência cardíaca ao final do experimento, taquipnéia associada a derrame pleural...
Considering that, in studies analyzing the relationship between cardiac remodeling and supravalvar aortic stenosis, the early detection of ventricular dysfunction is important, the hemodynamic method is ideal to detect such dysfunction although it is inadequate for sequential studies, tachypnea is generally manifested when severe cardiac deterioration exists and that the relationship between functional capacity and ventricular function has not been established, it is necessary to identify whether the first sign(s) of exercise intolerance is(are) related to ventricular dysfunction. Hence, this study aimed at evaluating, in different periods - 3, 6, 12 and 18 weeks - after the induction of supravalvar aortic stenosis in rats, the following aspects: 1) function of the left ventricle at rest and cardiac morphological alterations by means of an echocardiogram; 2) exercise tolerance during an incremental test on a treadmill; 3) relationship between exercise tolerance and cardiac function determined at rest. Thirty-seven young male Wistar rats were used. The animals were separated into two groups: operated control (CG, n=13) and supravalvar aortic stenosis (GEAo, n=24). GEAo was submitted to surgery with the implantation of a clip on the aorta artery for induction of supravalvar aortic stenosis. GC was submitted to the same type of surgery although without clip implantation. The animals were given water and chow ad libitum and maintained in a controlledtemperature environment at 23°C and an inverted light-dark cycle. All the procedures were performed in the dark cycle by using red fluorescent illumination, whose long wave emission is not perceived by the animals. Of the 24 rats in the GEAo ten died and two presented signs of cardiac insufficiency at the end of the experiment, tachypnea associated with pleural stroke, thrombus in the left atrium and hypertrophia in the right ventricle, thus...

Dairy cows require a low-stress environment in order to efficiently produce milk, and thus stress management is a common focal point for both researchers and producers. A primary source of stress for dairy cattle is associated with the environment, particularly heat, and therefore a considerable amount of research has been done in an attempt to find ways of reducing heat stress. Most of the research, however, has focused on using heat abatement techniques to cool the cow, using evaporative cooling systems to reduce temperature in the environment thus also cooling the cow, and selective breeding to improve thermal tolerance. Whereas cow comfort has been improved, there are still negative responses to heat stress today including decreased milk production and altered milk composition. Cattle remove excess body heat primarily through evaporative and convective cooling in the respiratory system and exercise is likely to improve blood flow and efficiency of heat transfer within the lungs. Furthermore, exercise has been proven to improve performance in humans and horses. This study was designed to determine whether or not exercise improved fitness and heat tolerance, and to observe whether there were any resulting effects on milk production and parturition. Two experiments were carried out during the late summer/early fall of 2014 and summer of 2015. Each experiment utilized a different exercise regimen: experiment 1 used a combination of high-intensity intervals and endurance training, whereas experiment 2 involved an endurance regimen performed during the afternoon in early summer. Pregnant Holstein heifers (Experiment 1, n = 24; Experiment 2, n = 24) were exercised in an 8-panel motorized walker over a period of 8 wk that ended approximately 21 d prior to parturition. In experiment 1, fitness was improved in heifers that were exercised compared with their non-exercised counterparts based on their duration of exercise and speed of exercise at failure (P < 0.05). During a cool hour of the day after 6 wk of exercise, exercised heifers spent more time in body temperature zone 1 (< 39.0°C) compared with their non-exercised counterparts (P < 0.05). Exercised heifers also spent less time (P < 0.05) than non-exercised heifers in body temperature zone 3 (> 40.0°C) during the hottest hour of a hot day during the 6th week. No treatment effects (P > 0.10) were found for weekly milk components or milk production. In experiment 2, exercise resulted in greater milk protein and solids-not-fat (SNF) percentage (P < 0.05) compared with contemporaries that did not exercise; however, there was no difference in weekly milk production during the first 150 days (P > 0.10). Fat-corrected milk and energy-corrected milk were calculated and no difference was detected between treatments (P > 0.10). These results are the first to show that high-intensity intervals and endurance training exercise in pregnant dairy heifers can improve heat tolerance, increase production of milk protein and SNF, and perhaps increase animal comfort and well-being during hot weather.

Full textExercise intolerance is well documented in patients with chronic obstructive pulmonary disease (COPD). Historically, this exercise intolerance has been attributed to the central factors of lung damage and subsequent heart failure. However, recent evidence suggests that (i) patients with cardiac and renal failure suffer from skeletal muscle (SM) abnormalities that impair exercise tolerance and (ii) patients with chronic obstructive pulmonary disease (COPD) may have metabolic and functional abnormalities of SM. However, no studies have conducted a detailed investigation of SM structure and function and their relation to exercise tolerance in patients with COPD.

The physiological mechanisms determining the tolerable duration of exercise dictate human physical accomplishments across all spectrums of life. Despite extensive study, these specific mechanisms, and their dependence on oxygen delivery and oxygen utilization, remain, a certain extent, undefined. The purpose of this dissertation was to test the overarching hypothesis that muscle contraction characteristics (i.e., intensity of contraction, muscle contraction-relaxation duty cycle, etc.) alter oxygen delivery and oxygen utilization, which directly influence the power-duration relationship and fatigue development, and therefore, exercise tolerance. To accomplish this, specific interventions of altered muscle contraction-relaxation duty cycle and blood flow occlusion were utilized. In the first investigation (Chapter 2), we utilized low and high muscle contraction-relaxation duty cycles to alter blood flow to the active skeletal muscle, demonstrating that critical power (CP) was reduced with the high muscle contraction-relaxation duty cycle due to a reduction in blood flow, while the curvature constant (W’) was not altered. The second investigation (Chapter 3) utilized blood flow occlusion to show that CP was reduced and W’ increased for blood flow occlusion exercise conditions compared to control blood flow exercise conditions. The final investigation (Chapter 4) utilized periods of blood flow occlusion during and post-exercise to reveal greater magnitudes of peripheral and central fatigue development during blood flow occlusion exercise compared to control blood flow exercise. Moreover, this investigation demonstrated that W’ was significantly related to the magnitude of fatigue development. Collectively, alterations in oxygen delivery and oxygen utilization via muscle contraction characteristics and blood flow occlusion directly influence CP and the magnitude of fatigue development. However, W’ does not appear to be influenced by manipulations in oxygen delivery and oxygen utilization, per se. Rather, W’ may be determined by the magnitude of fatigue accrued during exercise, which is dependent upon oxygen delivery and oxygen utilization. The novel findings of the investigations presented in this dissertation highlight important physiological mechanisms that determine exercise tolerance and demonstrate the need for interventions that improve oxygen delivery and oxygen utilization in specific populations, such as those with chronic heart failure or chronic obstructive pulmonary disease, to improve exercise tolerance.

Respostas afetivas durante o exercício são relacionadas com a aderência ao exercício e com o comportamento atual/futuro de exercício. Entretanto, há grande variabilidade interindividual nas respostas afetivas ao exercício. Tal variabilidade é parcialmente explicada por diferenças individuais na preferência e tolerância da intensidade de exercício. Assim, os objetivos dessa tese de doutorado foram: Artigo 1 – adaptar o Questionário de Preferência e Tolerância da Intensidade de Exercício para a população brasileira e realizar uma avaliação psicométrica inicial; Artigo 2 – testar a validade estrutural do Questionário em uma amostra populacional diversa e avaliar sua invariância fatorial entre subgrupos de sexo e idade; Artigo 3 – explorar os fatores associados com a Preferência e Tolerância da intensidade de exercício em uma amostra populacional diversa, assim como fornecer valores normativos populacionais; Artigo 4 – testar se os constructos de preferência e tolerância da intensidade de exercício são associados com o comportamento de exercício longitudinalmente em uma amostra populacional diversa. Para isso, os seguintes métodos foram utilizados: Artigo 1 – tradução e retrotradução, produção de uma versão do Questionário em Português Brasileiro, e avaliação psicométrica e validação de constructo usando correlações transversais entre os escores de Preferência e Tolerância e variáveis de atividade física; Artigo 2 – análise fatorial confirmatória e teste de invariância fatorial multigrupos da versão em Português Brasileiro do Questionário em subgrupos de sexo e idade em uma amostra populacional de 622 participantes; Artigo 3 – regressão linear múltipla entre os escores de Preferência e Tolerância com idade, sexo, IMC, e atividade física no tempo de lazer (AFTL) moderada e vigorosa em uma amostra populacional de 622 participantes; Artigo 4 – regressões lineares múltiplas, correlações parciais e regressões logísticas multinomais envolvendo variáveis demográficas e antropométricas, assim como o comportamento de exercício tanto de 2007-2008 como de 2014-2015 de 622 participantes. Os resultados foram: Artigo 1 – A versão em Português do Brasil do PRETIEQ reteve as propriedades psicométricas da versão original, demonstrando adequada consistência interna, confiabilidade teste-reteste e correlações transversais com variáveis de atividade física dentro adultos jovens. Artigo 2 – a versão em Português do Brasil do PRETIE-Q reteve as propriedades estruturais da versão original e demonstrou invariância para sexo e idade. Artigo 3 – dentro alguns preditores significativos, apenas idade (r = - 0,348 e r = -0,341) e AFTL vigorosa (r = 0,276 e r = 0,140) foram significativamente e independentemente associadas com os escores de Preferência e Tolerância, respectivamente. Além disso, valores normativos populacionais estratificados por categorias de idade são apresentados. Artigo 4 – controlando por idade, sexo, IMC e níveis passados de AFTL, o aumento em 1 unidade nos escores de Preferência e/ou Tolerância foram associados com ≈5min/semana de AFTL total, ≈2min/semana de AFTL moderada e ≈2min/semana de AFTL vigorosa. Além disso, considerando os níveis recomendados de AFTL, o aumento de 1 unidade dos escores de Preferência e/ou Tolerância foram associados com ≈4-6%, 12,4% e 9,1% maiores chances de atingir longitudinalmente os níveis recomendados de AFTL total, moderada ou vigorosa, respectivamente.
Affective responses during exercise are related to exercise adherence and current/future exercise behavior. However, there is large inter-individual variability in affective responses to exercise. Such variability is partly explained by individual differences in preference for and tolerance of the intensity of exercise. Thus, the aims of this PhD thesis were: Article 1 – to adapt the Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) for the Brazilian population and to perform an initial psychometric evaluation; Article 2 – to test the structural validity of the PRETIE-Q in a diverse population sample and to evaluate its factorial invariance across gender and age subgroups; Article 3 – to explore the factors associated with Preference for and Tolerance of the exercise intensity in a diverse population sample, as well as to provide population-based normative values; Article 4 – to test whether the constructs of preference for and tolerance of exercise intensity are associated to exercise behavior longitudinally in a diverse population sample. For this, the following methods were used: Article 1 – translation and back-translation, production of a Brazilian Portuguese version of the PRETIE-Q, and psychometric evaluation and construct validation using cross-sectional correlations between the Preference and Tolerance scores and physical activity variables; Article 2 – confirmatory factor analysis and a test of multigroup factor invariance of the Brazilian Portuguese version of the PRETIE-Q across gender and age subgroups in a population sample of 622 participants; Article 3 – multiple linear regression between Preference and Tolerance scores with age, gender, BMI and moderate and vigorous leisure-time physical activity (LTPA) in a population sample of 622 participants; Article 4 – multiple linear regressions, partial correlations and multinomial logistic regressions involving demographic and anthropometric variables, as well as exercise behavior from both 2007-2008 and 2014-2015 of 622 participants. The results were: Article 1 – The Brazilian Portuguese version of the PRETIE-Q retained the psychometric properties of the original, demonstrating adequate internal consistency, testretest reliability, and cross-sectional correlations with physical activity variables among young adults. Article 2 – The Brazilian Portuguese version of the PRETIE-Q retained the structural properties of the original and demonstrated gender and age invariance. Article 3 – among a few significant predictors, only age (r = -0.348 and r = -0.341) and vigorous LTPA (r = 0.276 and r = 0.140) were found to be significantly and independently associated with both Preference and Tolerance scores, respectively. In addition, population-based normative values stratified by age categories are presented. Article 4 – controlling for age, gender, BMI and past LTPA levels, a 1-unit increase in Preference and/or Tolerance scores was associated with additional ≈5min/week of total LTPA, ≈2min/week of moderate LTPA and ≈2min/week of vigorous LTPA. In addition, considering the recommended levels of LTPA, a 1-unit increase in Preference and/or Tolerance scores was associated with ≈4-6%, 12.4% and 9.1% greater odds of longitudinally attaining the recommended levels of total, moderate and vigorous LTPA, respectively.

Thus, the aims of this PhD thesis were: Article 1 - to adapt the Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) for the Brazilian population and to perform an initial psychometric evaluation; Article 2 - to test the structural validity of the PRETIE-Q in a diverse population sample and to evaluate its factorial invariance across gender and age subgroups; Article 3 - to explore the factors associated with Preference for and Tolerance of the exercise intensity in a diverse population sample, as well as to provide population-based normative values; Article 4 - to test whether the constructs of preference for and tolerance of exercise intensity are associated to exercise behavior longitudinally in a diverse population sample. For this, the following methods were used: Article 1 - translation and back-translation, production of a Brazilian Portuguese version of the PRETIE-Q, and psychometric evaluation and construct validation using cross-sectional correlations between the Preference and Tolerance scores and physical activity variables; Article 2 - confirmatory factor analysis and a test of multigroup factor invar...

Resumo: Avaliar as características de atividades físicas na vida diária de pacientes brasileiros portadores de DPOC e sua relação com diferentes variáveis fisiológicas. Métodos: Quarenta pacientes brasileiros portadores de DPOC (18 homens; 66±8 anos; VEF1 46±16%pred; IMC 27±6 Kg.m-2) e 30 idosos saudáveis foram avaliados quanto às atividades físicas na vida diária utilizando-se um acelerômetro multiaxial (Dynaport Activity Monitor, Holanda) por 12 h/dia durante 2 dias da semana. Foram ainda avaliados: capacidade máxima e funcional de exercício (teste incremental máximo e teste de caminhada de 6 minutos [TC6], respectivamente), pressões máximas inspiratória e expiratória (PImax e PEmax, respectivamente), força muscular periférica (1 repetição máxima e força de preensão manual), qualidade de vida (Saint George Respiratory Questionnaire [SGRQ]), estado funcional (questionário London Chest Activity of Daily Living [LCADL]) e sensação de dispnéia (escala do Medical Research Council [MRC]). Resultados: Pacientes portadores de DPOC apresentaram menor tempo gasto andando/dia quando comparados aos idosos saudáveis (55±33 versus 80±28 min/dia; p=0,001) e menor intensidade de movimento (1,9±0,4 versus 2,3±0,6 m/s2; p=0,004). Os pacientes com DPOC também tenderam a passar mais tempo sentados (294±114 versus 246±122 min/dia; p=0,08). O tempo andando/dia correlacionou-se com TC6 (r=0,42; p=0,007), carga máxima de trabalho (r=0,41; p=0,009), idade, MRC e domínio atividade do SGRQ (-0,31≤ r ≤-0,43; p≤0,05 para todos). Conclusão: Apesar de serem mais ativos do que pacientes europeus estudados previamente, pacientes brasileiros portadores de DOPC são menos ativos em comparação a idosos saudáveis. O tempo gasto andando/dia é apenas moderadamente relacionado à capacidade máxima e funcional de exercício
Abstract: To evaluate the characteristics of physical activities in daily life in Brazilian patients with Chronic Obstructive Pulmonary Disease (COPD) and the relationship of these characteristics with different physiologic variables. Methods: Forty Brazilian COPD patients (18 men; 66±8 years; FEV1 46±16%pred; BMI 27±6 Kg.m-2) and 30 healthy age- and sex-matched subjects performed assessment of physical activity in daily life with an accelerometerbased activity monitor (Dynaport Activity Monitor, The Netherlands) for 12 h/day in 2 weekdays. Other measurements included maximal and functional exercise capacity (incremental exercise test and six-minute walk test [6MWT], respectively), maximal inspiratory and expiratory pressures, peripheral muscle force (1-repetition maximum and handgrip force), quality of life (Saint George Respiratory Questionnaire, SGRQ), functional status (London Chest Activity of Daily Living questionnaire) and dyspnea sensation (Medical Research Council scale, MRC). Results: COPD patients had lower daily time spent walking in comparison to healthy elderly (55±33 versus 80±28 min/day; p=0.001) as well as reduced movement intensity (1.9±0.4 versus 2.3±0.6 m/s2; p=0.004). In addition, COPD patients also tended to have more daily sitting time (294±114 versus 246±122 min/day, p=0.08). Time spent walking in daily life was correlated with 6MWT (r=0.42; p=0.007), maximal workload (r=0.41; p=0.009), age, MRC scale and SGRQ activity domain (-0.31 ≤ r ≤ -0.43; all p≤0.05). Conclusion: Despite being more active than previous reports of European COPD cohorts, Brazilian patients with COPD are less active in comparison to healthy elderly. Daily time spent walking in real life is only moderately related with maximal and functional exercise capacity

Full textThe beneficial effects of regular, moderate exercise are well estabilished. On the other hand, the effects caused by the heavy and exhaustive exercise for longer periods are controversial. Some of these unpleasant effects. may be oxidative stress, the oxidation of the native LDL and acuse phase inflammatory response. Objective: Assess these variables in marathon runners. The acute effects were assessed immediately and 72 hours after the race, the chronical effects were assessed in basal condition and in comparision with the control group. Methods: A population consisting of 27 marathon runners, male, 41± 8 y old, 74% white, healthy and 26 matchable controls. Results: 1) On basal conditions (marathon runners X control group) regarding oxidative profile, the findings were the following: a) Total Anti-oxidant State of the plasma (TAS); 3.76 ± 0.34 versus 3.45 ± 0.35 mmol/L , p=0.002; b) Peroxides 0.48± 0.15 versus 0.65± 0.42, p=0.011 c) Anti ox LDL antibodies, and oxLDL without a significative difference. In the immunoinflamatory profile the findings are the following observed: a) us CRP; 1.49± 1.11 versus 1.03± 1.36, mg/L, p=0.004; b) IL-15; 42.83± 109.47 versus 4.80± 128.57 pg/ml, p=0.021; c) TNF-alfa 8.07± 13 versus 33.98± 39.63 pg/ml. 2) Marathon runners´ basal conditions versus their condition immediately after the race. a) OxLDL; 88.18± 22.05 versus 148.46± 74.76 U/L, p<0.001; b) Interleukynes: IL-6=30.08± 40.66 versus 113.61± 91.39, pg/ml p<0.05, IL-8=38.63± 36.57 versus 85.02± 53.91,pg/ml, p<0.05, IL-10=21.08± 36.12 versus 141.82± 124.98,pg/ml, p<0.05, IL-15=42.83± 109.47 versus 169.60± 244.84 pg/ml, p<0.05, e TNF-alfa=8.07± 13 versus 32.65± 42.24, ph/ml, p<0.05; c) leucocytes; 5.581± 1.122 versus 13.807± 5.393, mil/ml, p<0.05; d) skeletal muscle markers: myoglobine; 41± 31 versus 659± 344,ng/ml, p<0.05 (>1600%); CPK; 205± 121 versus 403± 134, p<0.05; DHL; 107± 28 versus 302± 44 U/L, p<0.05. e) Myocardial markers: CKMB-mass; 2.65± 2.43 versus troponina I; 0.023± 0.032 versus 0.045± 0.044, ng/ml, p<0.05. 3) Marathon runners´ basal conditions versus their condition 72 hours after the race: a) TAS; 3.76± 0.34 versus 3.39± 0.92 U/L, p=0.05; b) Anti-oxLDL antibodies; 439.23± 409.65 versus 225.10± 489.16, U/L, p<0.001; c) Peroxides= 0.41± 0.15 versus 0.49± 0,11 U/L, p=0.03. Regarding the oxidative profile, the following was found: a) us CRP 1.49± 1.11 versus 3.15± 2.22, mg/l, p<0.05; b) IL-8; 38.36± 36.57 versus 45.28± 25.21pg/ml, p<0.05.

CAPES
A doença pulmonar obstrutiva crônica (DPOC) é uma desordem respiratória associada à disfunção muscular esquelética e ao desenvolvimento de hiperinsuflação pulmonar o que contribui para dispneia e redução da tolerância ao exercício. O alongamento dos músculos da caixa torácica e a vibração de corpo inteiro surgem como terapias alternativas para recuperar a função muscular e melhorar a capacidade funcional. Os objetivos desta dissertação foram: 1. Avaliar os efeitos agudos de um programa de alongamentos da musculatura da caixa torácica sobre a mobilidade diafragmática e a cinemática toracoabdominal de pacientes com DPOC durante o exercício; 2. Avaliar a qualidade da evidência da literatura dos efeitos da vibração de corpo inteiro (VCI) sobre a capacidade funcional de pacientes com DPOC. Foi realizado um ensaio clínico composto por 14 pacientes com DPOC, 6 hiperinsufladores severos (HS) e 8 não hiperinsufladores (NH). Os pacientes foram divididos em dois grupos: Alongamento (GA) e Controle (GC) e tiveram avaliadas a mobilidade diafragmática bem como o padrão ventilatório e os volumes da parede torácica antes da intervenção (GA ou GC) e após exercício de carga constante em bicicleta ergométrica. Os resultados mostraram aumentos no volume corrente abdominal (p<0,001), mobilidade diafragmática (p=0,030), além de maiores valores de saturação periférica de oxigênio (p=0,024) no GA em relação ao GC nos pacientes com HS; e redução da frequência respiratória (p=0,023), aumento do volume inspiratório final (p=0,004) e menor sensação de fadiga de membros inferiores (p=0,043) no GA em relação ao GC nos pacientes NH. A sessão de alongamentos não foi capaz de aumentar a tolerância ao exercício. Também foi desenvolvida uma revisão sistemática e metanálise que incluiu quatro artigos envolvendo 185 pacientes, todos os estudos mostraram aumento na distância percorrida no teste de caminhada de seis minutos no grupo com VCI em relação ao controle (57,85 m; IC 95% 16,33-99,33). A qualidade da evidência foi moderada. Concluímos que o alongamento dos músculos da caixa torácica pode trazer benefícios agudos para os pacientes com DPOC, principalmente naqueles que apresentam hiperinsuflação dinâmica severa e que a vibração de corpo inteiro é capaz de melhorar a capacidade funcional de pacientes com DPOC.
Chronic obstructive pulmonary disease (COPD) is a respiratory disorder associated with skeletal muscle dysfunction and the development of lung hyperinflation which contributes to dyspnea and reduced exercise tolerance. Stretching the muscles of the rib cage and the whole body vibration emerge as alternative therapies to restore muscle function and improve functional capacity. The objectives of this study were: 1. To assess the acute effects of a stretching program for the muscles of the rib cage on the diaphragmatic motion and kinematics thoracoabdominal patients with COPD during exercise; 2. To assess the quality of evidence from the literature of the effects of whole body vibration (WBV) on the functional capacity of patients with COPD. It conducted a clinical trial comprising 14 patients with COPD, 6 severe hyperinflators (SH) and 8 non hyperinflators (NH). Patients were divided into two groups: Stretching (SG) and control (CG) and were evaluated diaphragmatic mobility and the ventilatory pattern and volume of the chest wall before the intervention (SG or CG) and after constant load exercise bicycle exercise. The results showed increases in abdominal tidal volume (p <0.001), diaphragmatic mobility (p = 0.030), as well as higher peripheral oxygen saturation values (p = 0.024) in SG than the CG in patients with SH; and reduced respiratory rate (p = 0.023), increased end-inspiratory volume (p = 0.004) and less sense of fatigue of the lower limbs (p = 0.043) in SG than the CG in NH patients. The stretching session was not able to increase exercise tolerance. It was also developed a systematic review and meta-analysis that included four articles involving 185 patients, all studies showed an increase in the distance covered on the six-minute walk test in the group with VCI compared to the control (57.85 m; 95% CI 16.33 to 99.33). The quality of evidence was moderate. We conclude that the stretching of the muscles of the rib cage can bring benefits for acute COPD patients, particularly those with severe dynamic hyperinflation and the whole-body vibration can improve the functional capacity of patients with COPD.
