INTRODUÇÃO: O treinamento de força tem sido eficiente em idosas, mas sua relação com a autopercepção de saúde ainda não está clara na literatura. OBJETIVO: O presente estudo teve como objetivo analisar os efeitos de um programa de treinamento com pesos sobre a força muscular e a autopercepção de saúde em idosas na cidade de Jequié-BA. METODOLOGIA: A amostra foi composta por 17 idosas com idade média de 68,76±5,95 anos. A força muscular foi avaliada pelo teste de estimativa de uma repetição máxima (1RM); o treinamento foi realizado em duas sessões semanais, compostas de duas séries de 10 RM para cada um dos exercícios, com intensidade variando de 50% a 70% de 1RM e duração de oito semanas. Os dados foram analisados por meio da estatística descritiva, do teste t de Student pareado e do teste Qui-quadrado não-paramétrico, com nível de significância de p<0,05. RESULTADOS: A força muscular aumentou significativamente (p<0,05), houve também aumento na proporção de idosas que relataram autopercepção de saúde positiva, mas não houve diferença estatisticamente significativa após o treinamento. CONCLUSÃO: Pode-se concluir que o método de treinamento de força aplicado promoveu respostas significativas no aumento da força muscular e mudanças positivas na autopercepção de saúde referida pelas idosas.
BACKGROUND: Studies have shown that physical activity levels can be inversely associated with high-sensitivity C-reactive protein (hs-CRP) levels. However, the amount of physical activity required to maintain normal hs-CRP levels is still a matter for speculation. OBJECTIVE: To identify the amount of physical activity necessary to discriminate the hs-CRP levels in adults. DESIGN AND SETTING: Cross-sectional study at six teaching and research institutions. METHODS: The study sample comprised 10,231 adults aged 35 to 74 years who were participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Receiver operating characteristic (ROC) curves were constructed to compare the amount of physical activity in two domains (leisure time and commuting) with hs-CRP levels. The sensitivity and specificity were calculated to identify the best cutoff for physical activity level that would be needed to maintain normal levels of hs-CRP (< 3 mg/l). RESULTS: The area under the ROC curve was only statistically significant for discriminating normal levels of hs-CRP according to the amount of physical activity when the two study domains were added together. The accumulated physical activity level of 200 minutes/week was the best cutoff for discriminating normal levels of hs-CRP in adults of both sex. CONCLUSIONS: Physical activity in the leisure-time and commuting domains together, of duration 200 minutes/week, was associated with normal hs-CRP values.

Background Resistance training is used in different exercise programs, with different objectives and different levels of physical fitness. Training-related variables, such as volume, rest time and intensity, can affect the response of blood pressure (BP), but studies on the effect of these variables on BP are still needed. Objective To evaluate the acute response of BP in trained individuals undergoing two different methods of resistance training. Methods The sample was divided into three groups: (1) the German volume training [...] Abstract Background Resistance training is used in different exercise programs, with different objectives and different levels of physical fitness.

Introduction: Mind-body therapies encompass a series of practices that make use of meditation exercises, relaxation, mindfulness, controlled breathing, postures and smooth movements, in order to lead its practitioners to healthy psychophysical conditions. In times of quarantine and social distancing, online strategies are necessary to enable the access to healthcare. This work aims to present mind-body therapies, through telemedicine, as a resource for the decrease of number of injuries, and the promotion of health in times of quarantine and social distancing. Methods: The ideas that are shown in this paper are based on contents of articles that had been published in scientific journals, and that had been complemented by the theoretical and practical knowledge of the authors in this area of knowledge. Results: Studies show that online mind-body therapies can provide positive effects on physical, mental and emotional components that are related to health in different contexts. Conclusion: In times of pandemic, mind-body therapies through telemedicine appear as important complementary resource of the strategies that aim the decrease of diseases and promotion of health, in situations of quarantine and social distancing.
