Examining factors that affect vitamin D status in the fast-growing elderly population of Miami-Dade, Florida, is needed. Vitamin D deficiency in older adults has been linked to correlates of disability, including falls and fractures, and cardiovascular disease. The purpose of this study was to determine the proportion of vitamin D insufficient individuals and their relationship with vitamin D insufficiency in older adults (n=97) living in Miami-Dade. We evaluated the association between vitamin D status and 1) dual task physical performance to understand the link between vitamin D and cognition in the context of mobility; and 2) cardiometabolic risk, measured by galvanic skin response, pulse oximetry, and blood pressure to create a composite score based on autonomic nervous system and endothelial function. Participants completed baseline assessments that included serum levels of vitamin D, anthropometrics, body composition, dual task physical performance and cardiometabolic risk. Surveys to evaluate vitamin D intake, sun exposure, physical activity, and depressive symptoms were completed. Spearman’s correlations, independent t-tests, paired t-tests, repeated measures ANOVAs, and multiple logistic and linear regressions were used to examine the relationship of vitamin D insufficiency (25(OH)D /ml) and sufficiency (25(OH)D ≥30 ng/ml) with determinants of vitamin D status, dual task physical performance variables and cardiometabolic risk scores. Although the proportion of vitamin D insufficient individuals was lower when compared to the prevalance of the general United States elderly population, it was still common in healthy community-dwelling older adults living in Miami-Dade County, especially among Hispanics. Factors that affected skin synthesis (ethnicity, and sun exposure), and bioavailability/metabolism (obesity) were significant predictors of vitamin D status. Vitamin D insufficiency was not significantly correlated with worse dual task physical performance; however, cognitive performance was worse in the vitamin D insufficient group. Our results suggest a relationship of vitamin D insufficiency with executive dysfunction, and support an association with cardiometabolic risk using an innovative electro-sensor complex, possibly by modulating autonomic nervous system activity and vascular function, thus affecting cardiac performance.

Purpose: This paper attempts to develop production functions (PF) between aerobic exercise inputs and long-run health outputs. Future studies could use such PF for estimating the benefits and costs (broadly defined) of different exercise programs to help develop optimal (utility maximizing) ones. Methods: To develop the PF, the paper reviewed the biomedical literature for the major dose-response relations between health, physical fitness, and exercise. Where relevant, the paper converted the dose-response relationships from relative risks to absolute probabilities and standardized terminology and units of measures. Results: The paper develops a clear set of biological PF that illustrate, quantitatively, how increases in peak cardiorespiratory (CR) fitness as measured by a short stress test reduce the probability of all-cause mortality; how increasing intensities of short (approximately 30 min, three to five times a week) exercise sessions increase peak CR fitness or retard its age-related decline; and how consistent exercise reduces the risk of myocardial infarctions (MI). Conclusions: The exercise-long-run health PF developed in this paper should provide a useful framework for other studies to estimate the broadly defined costs and benefits of different exercise programs and to help develop optimal ones.

Förlust av muskelmassa med åldrande försämrar den fysiska funktionen, vilket även minskarlivskvaliteten och kan leda till svaghet och för tidig död. Omega-3-fettsyror stimulerar protein-anabolism och kan därför vara användbart för att förebygga och behandla sarkopeni. Syfte:Syftet med denna studie var att utvärdera effekten av omega-3-fettsyra-tillskott på graden avmuskelproteinsyntes hos vuxna. Metod: Studien är utförd som en litteraturstudie där relevantavetenskapliga och publicerade studier utvärderats och dess resultat har analyserats för attbesvara studiens syfte. Studiernas relevans bedömdes utifrån artiklarnas titel och abstrakt. 234studier i Onesearch, 5 studier i PubMed gicks igenom till en början. 30 abstrakt lästes, 21studier lästes i fulltext, 7 studier baserat på in- och exklusionskriterierna valdes ut till studienefter läst fulltext. Resultat: De flesta studier har utvärderat effekten av omega-3-tillskott hosyngre vuxna 18-30 år och äldre vuxna 65 år och äldre. Även om det finns en relativ brist påstudier som utvärderar effekten av omega-3-tillskott på muskelproteinsyntes (MPS) hos vuxna30-70 år, verkar det som om omega-3 kan främja anabola ökningar vid styrketräning hos äldreindivider. Slutsats: Ytterligare forskning behövs inom detta område för att dra relevantaslutsatser. Denna litteraturstudie drar slutsatsen att omega-3-fettsyror stimulerar syntesen avmuskelprotein hos vuxna och kan vara användbart för att förebygga och behandla sarkopeni. / Loss of muscle mass with aging impairs physical functions, but also reduces quality of life andcan lead to weakness and premature death. Omega-3 fatty acids stimulate protein anabolism andmay therefore be usefull to treat sarcopenia. Purpose: The aim of this study was to evaluate theeffect of omega-3 fatty acid supplements on the degree of muscle protein synthesis in adults.Metod: The study is conducted as a literature study where relevant scientific and publishedstudies, evaluations and its results have been analyzed to answer the purpose of the study. Therelevance of the studies were assessed on the basis of the title and abstract of the articles. 234studies in Onesearch, 5 studies in PubMed were initially reviewed. 30 abstracts were read, 21studies were read in full text, based on the inclusion and exclusion criteria 7 studies wereselected for the study after reading in full text. Results: Most studies have evaluated the effect ofomega-3 supplements in younger adults (18-30 years) and older adults (65 years and older).Although there is a relative lack of studies evaluating the development of omega-3 supplementson MPS in adults 30-70 years, it seems that omega-3 can promote anabolic increases in olderindividuals. Couclusion: Further research is needed in this area to draw relevant conclusions.This literature review concludes that omega-3 fatty acids stimulate the synthesis of muscleprotein in adults and may be useful to prevent and treat sarcopenia.

This investigation examined the ability of the self-reported Veterans Specific Activity Questionnaire (VSAQ) and the Yale Physical Activity Survey (YPAS) to predict an individual’s performance on a timed walking assessment. Twenty subjects 65 years of age and older (73.5 ± 4.8) volunteered for the study. There were 13 women and nine men. Subjects participated in an individual interview in which the VSAQ and the YPAS were administered. The subjects then participated in a timed 25 meter walking test (16.5 ± 2.5). The 25 meter walking test was given twice and the times for each individual was averaged. Descriptive analysis of the YPAS demonstrated that the predominant reported level of energy expenditure was used for work activities (50% ± 18.4). The least amount of calories for the entire group was expended in caretaking with a mean percentage of 3.3% (± 6.1). Exercise was the second highest calorie expending category with 21.9% (± 14.0) of total calories. However, recreational activities were a close third with a mean of 17% (± 19.0). Yard work represented 7.8% (± 7.8) of total calories. The mean score for the VSAQ was 7.4 (± 3.4). The regression analysis demonstrated that age, gender, and VSAQ score were significant predictors of physical performance on the walking test (p<0.05) (Time= -1.78 +0.274 Age +2.22 Gender - 0.366 VSAQ). The r-squared value for this was 62.5%. Performance time was significantly predicted by adding the selected values from the YPAS (exercise and work) and the value from the VSAQ (Time= 18.5 - 0.566 VSAQ +0.0568 %Exer + 0.0350 %Work). The r-squared value for this was 52.6%. There was also a significant correlation (p<0.05) between age, time, and performance (r²=0.5). Therefore, the VSAQ appears to be an alternative assessment tool for physical activity in this selected elderly population. / Master of Science

In our work we analyzed the performance of the members 14-15 years old of the sport centres (SpS) 2014 . We compared the members of SpS with school population from the study of Pávek (1977). The basic motoric tests were 50 m run, standing long jump, the medicine ball throw 2kg and the 12 minute run. The memberes of SpS 2014 were significantly better than school population from the study of Pávek (1977). We compared the meberes of SpS with the athletes of ČSTV (1982). The athletes of ČSTV (1982) were significantly better than the meberes of SpS 2014 in motoric tests: standing long jump and 12 minute run. Furthermore, we found that general physical performance of sprinters specifically reflected in their athletic performance.

Abstract The purpose of the study was to describe and evaluate the measured and self-reported physical performance of the elderly people who relocated to senior housing and their change 3 and 12 months after the relocation. Besides, the association of self-reported physical performance, social environment and psychological well-being with measured physical performance changes was examined. The objective of the research was to provide information that can be used in the design and management of practices that aim to assess and support the physical performance of those living in senior housing. Data were collected from elderly (n = 81) who moved to senior housing in northern Finland (n = 11) in 2014, and 70% of them were women. The indicators that were used were the Oldwellactive Questionnaire, the Environmental Support instrument and the Short Physical Performance Battery [SPPB]. The data were analyzed with statistical methods. Physical performance of those who relocated to senior housing was weak. Instrumental Activities of Daily Living [IADL], walking speed, right hand grip strength and self-reported IADL significantly decreased during their first year of residence. Besides, self-reported IADL performance became more difficult but muscle strength training, as well as participation in hobby groups increased. Residents estimated that they can do what they want, and they can sufficiently meet their loved ones in the senior housing. Self-reported physical performance was associated with the deterioration of performing IADL and the slowdown of walking speed. Social environment and psychological well-being were associated with the deterioration of performing IADL, the slowdown of walking speed and the weakening of the dominant hand´s grip strength. This research provides more information about the physical performance, the social environment and the psychological well-being of the elderly who relocated to senior housing. Research results will help service providers to improve the procedures that aim to the physical performance assessment and support of the residents, paying attention to the impact of the elderly’s individuality in requirements associated with the realization of the services. Research results show that organizations maintaining senior housing must organize exercise areas suitable for the residents and the means for indoors and outdoors muscle training and balance exercise. Individual factors related to physical performance, social environment and psychological well-being of the residents should be considered in the design, implementation and management of these services. / Tiivistelmä Tutkimuksen tarkoituksena oli kuvata ja selittää palvelutaloon muuttaneiden ikääntyneiden mitattua ja itsearvioitua fyysistä toimintakykyä ja niiden muutosta 3 ja 12 kuukautta muuton jälkeen. Lisäksi kuvattiin itsearvioidun fyysisen toimintakyvyn, sosiaalisen ympäristön ja psyykkisen hyvinvoinnin yhteyttä mitatun fyysisen toimintakyvyn muutoksiin. Tutkimuksen tavoitteena oli tuottaa tietoa, jota voidaan hyödyntää palvelutalojen asukkaiden fyysisen toimintakyvyn arvioimiseen ja tukemiseen tähtäävien käytäntöjen suunnittelussa ja johtamisessa. Aineisto kerättiin pohjoissuomalaisessa kaupungissa palvelutaloihin (n = 11) vuonna 2014 muuttaneilta ikääntyneiltä (n=81), joista 70 % oli naisia. Mittareina käytettiin Hyvinvointiprofiili-kyselylomaketta, Ympäristöhyvinvointimittaria ja SPPB- toimintatestiä (Short Physical Performance Battery). Aineisto analysoitiin tilastollisin menetelmin. Palvelutaloon muuttaneiden fyysinen toimintakyky oli heikko. Päivittäisistä toiminnoista suoriutuminen [IADL], kävelynopeus, oikean käden puristusvoima ja itsearvioitu arkiaskareista suoriutuminen heikkenivät ensimmäisen asumisvuoden aikana. Lisäksi itsearvioitu IADL-suoriutuminen vaikeutui mutta lihaskuntoharjoittelu sekä harrastusryhmiin osallistuminen lisääntyivät. Asukkaat arvioivat voivansa tehdä, mitä haluavat ja tapaavansa riittävästi läheisiä ihmisiä palvelutalossa. Itsearvioitu fyysinen toimintakyky oli yhteydessä IADL-suoriutumisen vaikeutumiseen ja kävelynopeuden hidastumiseen. Sosiaalinen ympäristö ja psyykkinen hyvinvointi olivat yhteydessä IADL-suoriutumisen vaikeutumiseen, kävelynopeuden hidastumiseen ja oikean käden puristusvoiman heikkenemiseen. Tämä tutkimus lisää tietoa palvelutaloihin muuttaneiden ikääntyneiden fyysisestä toimintakyvystä, sosiaalisesta ympäristöstä ja psyykkisestä hyvinvoinnista. Tutkimustulokset auttavat ikääntyneiden asumispalveluiden tuottajia kehittämään asukkaiden fyysisen toimintakyvyn arviointiin ja toimintakyvyn ylläpitämiseen tähtääviä toimintamalleja, joissa huomioidaan ikääntyneiden yksilöllisyyden vaikutus palveluiden toteuttamiseen liittyviin vaatimuksiin. Tutkimustulokset osoittavat, että palvelutaloja ylläpitävien organisaatioiden tulee järjestää asukkaille soveltuvat liikuntatilat ja välineet sisä- ja ulkotiloihin lihaskunto- ja tasapainoharjoittelua varten. Asukkaiden yksilölliset fyysiseen toimintakykyyn, sosiaaliseen ympäristöön ja psyykkiseen hyvinvointiin liittyvät tekijät tulee ottaa huomioon palveluiden suunnittelussa, toteutuksessa ja johtamisessa.

O judô é um esporte de combate com características intermitentes, com alta demanda fisiológica. O desenvolvimento da potência aeróbia máxima em atletas de judô pode contribuir para a recuperação e a manutenção da intensidade dos esforços durante o combate, e para a recuperação entre os diferentes combates de uma competição. Em geral, a avaliação dessa capacidade física tem sido realizada por meio da aplicação de testes progressivos até a exaustão em esteira ou ciclo-ergômetro, os quais possuem baixa validade ecológica e não permitem a obtenção de parâmetros para a prescrição do treinamento específico da modalidade. Dessa forma, o objetivo deste estudo foi elaborar e testar a validade, reprodutibilidade e sensibilidade de um teste progressivo até a exaustão utilizando-se do uchi-komi (entrada de golpes), para mensurar a potência aeróbia máxima de atletas de judô. Doze atletas de judô do sexo masculino participaram desse estudo e foram submetidos a quatro sessões de avaliação, em dias distintos e, separadas por um intervalo de, no mínimo, 48 horas, exceto para a última sessão, que foi conduzido sete dias após a realização da terceira sessão. Para determinar a validade de critério, foram conduzidos três testes progressivos até a exaustão: teste de membros superiores (MMSSteste), membros inferiores (MMIIteste) e teste de uchi-komi (UKteste), os quais foram aleatorizados e distribuídos entre a primeira e a segunda sessões. Na etapa seguinte os mesmos atletas foram avaliados na terceira e quarta sessões para determinar a reprodutibilidade do UKteste. Além disso, também foi confirmado se os atletas alcançaram o verdadeiro consumo máximo de oxigênio, por meio de um teste de confirmação (UKconf). Para essa finalidade, 12 atletas de judô, incluindo 6 atletas que participaram do estudo de validade e reprodutibilidade, realizaram dois testes (UKteste e UKconf), separados por um intervalo de 20 minutos. A análise descritiva de todas as variáveis dependentes foi apresentada como média e desvio padrão. A validade do UKteste foi determinado por intermédio de uma análise de variância a um fator (tipo de teste) pela comparação do UKteste, MMSSteste e MMIIteste e pelo coeficiente de correlação de Pearson. Quando observada diferença significante, foi conduzido o teste de post-hoc de Bonferroni. A reprodutibilidade do UKteste foi determinada por meio do teste t de Student para dados pareados, coeficiente de correlação intraclasse (CCI), erro típico (ET) e ET como coeficiente de variação (CV). A sensibilidade do UKteste foi calculada pela menor variação detectável (MVD) para diferentes tamanho de efeito (0,2; 0,6 e 1,2 multiplicado pelo desvio padrão entre sujeitos) e classificados como marginal, médio, e bom, respectivamente. Além disso, a mínima mudança detectável (MMD) em uma dada variável foi calculada por meio da equação: ET x 1,96 * ?2. O nível de significância foi estabelecido em p < 0,05. A validade do UKteste foi confirmado pelo coeficiente de correlação de Pearson com valores de consumo pico de oxigênio (V? O2pico) classificados como quase perfeita. Não houve diferença nas variáveis mensuradas no UKteste e UKconf, além disso, os resultados mostraram que o UKteste possui boa reprodutibilidade relativa com CCI classificado como muito alta para a percepção subjetiva de esforço e quase perfeita CCI para o V? O2pico, frequência cardíaca máxima e intensidade aeróbia máxima. Adicionalmente, o teste apresentou boa reprodutibilidade absoluta, apresentando um ET como CV menor que 5%. Variações médias no tamanho do efeito podem ser adequadamente detectadas para o V? O2pico, intensidade aeróbia máxima e frequência cardíaca máxima. Em conclusão, o UKteste mostrou ser um teste válido e reprodutível para avaliar a potência aeróbia máxima de atletas de judô / Judo is a combat sport with intermittent characteristics and high physiological demand. The development of maximal aerobic power in judo athletes can contribute to the recovery and maintenance of efforts intensity during a combat, and to the recovery between different combats in a competition. In general, the evaluation of this physical capacity has been performed through the application of graded exercise tests in treadmill or cycle ergometer, which have low ecological validity, and do not enable the collection of parameters for specific training prescription to the modality. Thus, the objective of this study was to elaborate and test the validity, reliability and usefulness of a graded exercise tests using uchi-komi (repetition training), to measure the maximal aerobic power of judo athletes. Twelve male judo athletes participated in this study. They were submitted to 4 assessment sessions on different days separated by at least 48 hours, except in the last session which was performed 7 days after the 3rd session. In order to determine the criterion validity, 3 graded exercise tests were performed: upperbody (UBtest), lower-body cycle ergometer tests (LBtest) and uchi-komi (UKtest), which were randomized and distributed between 1st and 2nd sessions. In the next step, the same athletes were evaluated in the 3rd and 4th sessions to determine the reliability of the UKtest. Further, it was also confirmed whether athletes achieved true maximum oxygen uptake through a confirmation test (UKconf). For this purpose, 12 judo athletes, including 6 athletes who participated in the validity and reliability studies, performed 2 tests (UKtest and UKconf), separated by a 20-minute interval. The descriptive analysis of all dependent variables was presented by mean and standard deviations. The validity of the UKtest was determined through a one-way analysis of variance (test type), comparing the UKtest, UBtest and LBtest, and by the Pearson correlation coefficient. When a significant difference was observed, the Bonferroni post-hoc test was conducted. The UKtest reliability was determined by the test-retest comparison, using Student\'s t-test for paired data, intraclass correlation coefficient (ICC) and typical error (TE) as coefficient of variation (CV). The UKtest usefulness was calculated by the smallest worthwhile change (SWC) for different effect sizes (0.2, 0.6 and 1.2 multiplied by the standard deviation among subjects) and classified as marginal, average and good, respectively. In addition, the minimal detectable change (MDC) in each variable was calculated using the equation: TE × 1,96 × ?2. The significance level was set at p < 0.05. The validity of the UKtest was confirmed by the Pearsom correlation coefficient with values of peak oxygen consumption (V? O2peak) classified as nearly perfect. There were no differences between variables measured in the UKtest and in the UKconf. Also, results showed that the UKtest had good relative reliability, with ICC classified as very large (rated perceived exertion) and almost perfect (V? O2peak, maximal heart rate and maximum aerobic intensity). Moreover, the test presented good absolute reliability, with a TE as CV lower than 5%. Mean variations in effect size could be adequately detected for V? O2peak, maximal aerobic intensity and maximal heart rate. In conclusion, the UKtest proved to be a valid and reliable test to evaluate the maximal aerobic power of judo athletes

Bakgrund: Träning i naturliga miljöer har hälsofrämjande effekter och ökar välbefinnandet i jämförelse med träning som sker i inomhusmiljöer. Individer som utför träning i utomhusmiljöer visar sig ha högre hastighet, hjärtfrekvens och blodlaktatkoncentration, i jämförelse med individer som tränar inomhus vilket påverkar den fysiska prestationen.Syfte: Syftet med denna studie var att undersöka mätbara skillnader i fysisk prestation inomhus och utomhus genom ett maxpulstest.Metod: Studien genomfördes med en randomiserad kontrollerad cross- over design där åtta män och fem kvinnor (medelålder 26 ± 3.67), fysiskt aktiva, genomförde ett beeptest vid två tillfällen. Testet utfördes av samma person vid ett tillfälle inomhus och ett tillfälle utomhus. Analysen utgick från uppskattat VO2 max genom protokoll av beeptest, objektiv mätning och kontroll av puls direkt före tester och direkt efter genomförda tester.Resultat: Resultaten visade en signifikant skillnad i VO2 max (O2ml/kg/min) (p= 0.047), genom en högre fysisk prestation inomhus i jämförelse med utomhus (46.08 ± 8.76 och 44.73 ± 8.84). Puls (slag/min) efter genomförda tester visade ett högre medelvärde inomhus i jämförelse med utomhus (192.36 ± 10.13 och 190.45 ± 9.11), men ingen signifikant skillnad (p=0.11). Puls före tester visade ingen signifikant skillnad (p=0.898) mellan inomhusmiljön och utomhusmiljön (107.16 ± 18.78 och 107. 75 ± 18.49).Slutsats: Resultaten indikerar på att det är skillnader i fysisk prestation i olika miljöer. VO2 max var signifikant högre i inomhusmiljön i jämförelse med utomhusmiljön. Medel-maxpulsen tenderade ha ett högre medelvärde inomhus i jämförelse med utomhus. / Background: Exercise performed in natural environments produces health-promoting effects and increases well-being, in comparison with exercises performed in indoors-environments. Individuals who exercise outdoors has higher velocity, heartrate and blood lactate concentration compared to individuals who exercise indoors, which affects the physical performance.Purpose: The purpose of this study was to investigate measurable differences in physical performance indoors and outdoors through a maximum heartrate test.Method: The study was conducted with a randomized controlled cross over design where five women and eight men, physical active, in the middle age of 26 ± 3.67 years, performed a shuttle run test at two times. The test was repeated by the same individual one time indoors and one time outdoors. The analysis was made by estimated VO2 max using a protocol from the performed shuttle run test, and controlled objective measurements of pulse levels, directly before the test started and directly after finished test.Results: Significant differences were found between indoors and outdoors, where VO2 max (O2ml/lbs/min) (p= 0.047) was higher indoors than outdoors (46.08 ± 8.76 and 44.73 ± 8.84). Pulse levels (beats/min) was higher indoors than outdoors (192.36 ± 10.13 and 190.45 ± 9.11) after finished test, but significant differences were not found (p=0.11). Significant differences were not found in pulse levels before the test (p=0.898), between the different environments (107.16 ± 18.78 and 107. 75 ± 18.49).Conclusion: The results in this study show that there are differences in physical performance between different environments. VO2 max was significantly higher in the indoor environment compared to the outdoor environment. The average maximum pulse tended to have a higher average indoors compared to outdoors.

EMOTIKON-Studie benannte als Kurzform des Forschungsvorhabens zur “Interdisziplinäre(n) Evaluierung der motorischen Leistungsfähigkeit und des Gesundheitszustandes im Kontext sportlicher Eignung und Effizienz des Sportunterrichtes von GrundschülerInnen im Land Brandenburg“. Die Längsschnittstudie wurde durch den Arbeitsbereich Trainings- und Bewegungswissenschaft der Universität Potsdam, unter der Leitung von Prof. Dr. Ditmar Wick, an 29 Grundschulen der Schulämter Brandenburg/ Havel und Cottbus von 2006 bis 2010 realisiert. Mit der vorliegenden Publikation werden die Ergebnisse und deren Zusammenhänge zur Entwicklung der motorischen Leistungsfähigkeit, des Körperbaus, der Bewegungsaktivität und der Einschätzung des Sportunterrichts mit einführenden theoretischen Grundlagen und dem aktuellen nationalen Forschungsstand referiert. Die Autoren sind überzeugt, dass dieser Abschlussbericht nicht nur das Interesse der im aktuellen Forschungsprojekt „EMOTIKON-Grundschulsport 2010-2014“ involvierten Brandenburger Grundschulsportlehrer wecken wird, sondern auch den politischen Entscheidungsträgern (Schulämter, Ministerien) eine Entscheidungshilfe bieten als auch den Diskussionsprozess der im Themengebiet forschenden Wissenschaftler anregen kann. Diese Überzeugung gründet sich insbesondere auf die Ergebnisse zur körperlich-sportlichen Bewegungsaktivität der Dritt- bis Sechstklässler sowie der Analyse motorischer Leistung in Abhängigkeit von Geschlecht und soziodemografischen Gegebenheiten.

Diversas estrat?gias t?m sido utilizadas com o intuito de acelerar a recupera??o p?s-exerc?cio. Embora a imers?o em ?gua seja uma estrat?gia comum entre os atletas, a sua efic?cia na acelera??o da recupera??o ainda n?o est? estabelecida, e os efeitos da temperatura da ?gua na imers?o sobre o desempenho n?o s?o claros. Sendo assim, este estudo avaliou os efeitos da recupera??o passiva por imers?o em ?gua, em diferentes temperaturas, sobre o desempenho ap?s uma sess?o de exerc?cio. Nove homens, jovens, fisicamente ativos, participaram de quatro sess?es experimentais randomizadas compostas por exerc?cio exc?ntrico (3 x 10 repeti??es a 100% de uma repeti??o m?xima) e 90 minutos de corrida em esteira rolante a 70% do pico de consumo de oxig?nio. Em seguida, os volunt?rios recuperaram durante 45 minutos, distribu?dos em 15 minutos de imers?o em ?gua a 15, 28 ou 38?C sentados e 30 minutos deitados em repouso a temperatura ambiente (20 ? 2? C). Na sess?o controle (CON), durante a recupera??o, os volunt?rios permaneceram sentados durante 15 minutos ? temperatura ambiente. Quatro horas ap?s o final do exerc?cio experimental, os volunt?rios foram submetidos ? corrida de intensidade autorregulada m?xima de 5 km seguido do teste de Wingate para avaliar o desempenho f?sico. A temperatura retal (Tret), a frequ?ncia card?aca (FC) e sua variabilidade (VFC) foram medidas ao longo de toda a sess?o. O consumo excessivo de oxig?nio p?s-exerc?cio (EPOC) foi medido durante a recupera??o. Os marcadores do dano muscular, creatina quinase (CK) e aspartato amino transferase (AST) e a contagem de leuc?citos totais foram medidas antes e ap?s o exerc?cio, ap?s imers?o, antes e ap?s o desempenho, e 24 horas ap?s o exerc?cio experimental. A velocidade m?dia na corrida de intensidade autorregulada m?xima de 5 km e a pot?ncia pico relativano teste de Wingate n?o foram diferentes entre as condi??es experimentais. A imers?o em ?gua a 15?C reduziu a Tret, a FC e os ?ndices de VFC a valores de repouso, ap?s a recupera??o. O EPOC foi maior na imers?o em ?gua a 15?C e a 28?C. Durante a corrida de intensidade autorregulada de 5 km e do teste Wingate, a Tret e a FC n?o foram diferentes entre as condi??es experimentais. A sess?o de exerc?cio experimental induziu dano muscular e leucocitose. Entretanto, n?o houve diferen?a nos n?veis s?ricos de CK, AST e no n?mero de leuc?citos totais entre as condi??es experimentais. A recupera??o por imers?o em ?gua,a diferentes temperaturas, n?o foi efetiva em modificar o desempenho f?sico 4 horas ap?s uma sess?o de exerc?cio prolongado. / Disserta??o (Mestrado) ?

Several strategies have been used in order to accelerate post-exercise recovery. Although water immersion is a common strategy among athletes, it effectiveness in accelerate the recovery is not yet established, and the effects of temperature water immersion on performance are not clear. Thus, this study evaluated the effects of passive recovery water immersion at different temperatures on performance following an exercise session.Nine physically active men (24 ? 6 years old, 72 ? 13 kg, 177 ? 7 cm, peak oxygen consumption (VO2peak) of 55 ? 4 mL?kg- 1?min-1), participated of four randomized experimental sessions. Each session consisted of eccentric knee flexion (3 x 10 repetitions of 100% from one maximum repetition) and 90 minutes of treadmill running at 70% of VO2peak, followed by 15 minutes of passive recovery by water immersion at 15?C, 28?C or 38?C and 30 minutes resting in supine position at room temperature (20 ? 2?C). In the control session, volunteers remained seated for 15 minutes at room temperature after exercise. After four hours of resting, in order to evaluate recovery strategies, the volunteers underwent a 5 km of maximal self-paced treadmill running followed by the Wingate test. Prior to experimental sessions, rested volunteers completed 5 km of maximal self-paced running and the Wingate test, which were used as reference performance values. Rectal temperature (Tret), heart rate (HR) and heart rate variability indexes (HRV indexes) were measured through the entire session. Excess post-exercise oxygen consumption (EPOC) was measured during recovery period. The markers of muscle damage, creatine kinase (CK) and aspartate aminotransferase (AST) and total leukocyte count were measured before and after exercise, after immersion, before and after performance tests, and 24 hours after the experimental exercise. Average speed during 5 km of maximal self-paced treadmill running and relative peak power during Wingate test were not different between experimental conditions. Water immersion at 15?C reduced Tret, HR and HRV indexes to baseline values after recovery. EPOC was higher in water immersion at 15?C and 28?C. During 5 km of maximal self-paced treadmill running and Wingate test, Tret and HR were not different between experimental conditions. The experimental exercise session induced muscle damage and leukocytosis. However, there was no difference in serum CK, AST and total leukocyte count between experimental conditions.The recovery by water immersion at different temperatures was not effective in modify the physical performance 4 hours after a session of prolonged exercise.
