Resumo
Nos ultimos anos, muitos estudos foram realizados com o intuito de verificar os efeitos do exercicio fisico no padrao do sono. Porem, devido as diferencas metodologicas empregadas, principalmente com relacao a duracao e intensidade do exercicio fisico, ainda nao ha um consenso na literatura sobre a sua real influencia no sono. Alem disso, a grande maioria dos estudos utiliza apenas o exercicio aerobio como protocolo. Objetivo: Verificar, por meio das variaveis polissonograficas, o padrao do sono de individuos sedentarios com boa qualidade do sono, antes e apos a realizacao de diferentes tipos de exercicio fisico. Metodologia: Foram selecionados 102 voluntarios, 40 homens e 62 mulheres, com idade media de 28±7 anos. O protocolo experimental consistiu da realizacao de 3 tipos de exercicio fisico realizados de forma aguda: exercicio resistido (com carga obtida em cada aparelho equivalente a 50 por cento do teste de 1 repeticao maxima - 1 RM), aerobio (realizado em esteira, durante 30min a 60 por cento do V02pico) ou intervalado (realizado na bicicleta, com 10 repeticoes de 35s e carga equivalente a 140 por cento da carga maxima atingida no teste de esforco maximo). Os voluntarios foram submetidos a um exame de polissonografia (PSG) antes (basal) e no dia da realizacao do exercicio fisico, no intuito de se verificar os possiveis efeitos agudos do exercicio fisico no padrao do sono. Resultados: Nao foram observadas diferencas significativas entre os dados obtidos nas variaveis do sono da PSG realizada no dia do exercicio fisico, quando comparados a basal, em nenhum dos 3 tipos de exercicio. Conclusoes: De acordo com os resultados obtidos, uma unica sessao de exercicio fisico de intensidade moderada, independente do tipo de exercicio fisico realizado, nao altera o padrao do sono em voluntarios sedentarios e com boa qualidade do sono, provavelmente em decorrencia do baixo volume do exercicio fisico empregado no presente estudo
Introduction: In the last years, various studies have been carried out with the intention of verify the effects of physical exercise on sleep. However, different methodologies were employed, mainly relating to duration and intensity of physical exercise, but still there are not consense in the literature about the real influence of exercise on sleep. Further more, the majority of these studies utilized only the aerobic exercise as protocol. Objective: The aim this study was to verify the sleep pattern of sedentary volunteers with good sleep quality, before and after the realization of different types of physical exercise. Metodology: A total of 102 volunteers (40 male and 62 females, mean age 28 ± 7 years, sedentary and with good sleep quality) participated in the study. The protocol consisted of polysomnographic records (PSG) performed in the following night after 3 types of moderate exercise: resistance (50% of the onerepetition maximum - 1RM, 29 males and 41 females), aerobic (treadmill, 30min at 60% of VO2peak, 6 males and 13 females) or anaerobic (bike, 10 repetitions of 35s at 140% of the maximal workload reached, 5 males and 8 females). A comparison between basal PSG and exercise day PSG were realized using ttest and Wilcoxon test (p<0.05). Results: Despite several studies with acute exercise show significant alteration in some sleep parameters, especially slow wave sleep (SWS) and REM sleep, we did not found significant differences in the sleep parameters after performed 3 types of exercise. Conclusion: Our results showed that one session of exercise with moderate intensity did not interfere on sleep pattern of the sedentary volunteers with good sleep quality, probably in decorrence of low volume of physical exercise employed in the present study
