ABSTRACT Objective: To evaluate the effects of physical activity intensity, type and duration in patients with knee osteoarthritis (KOA) . Methods: A retrospective study of 195 KOA patients who were followed for two years after receiving educational material about KOA with or without attending classes. The patients were evaluated at baseline and 24 months. At the evaluations, the patients answered questionnaires pertaining to pain and function (WOMAC, Lequesne, VAS and SF-36); reported the intensity, duration and type of exercise performed per week; and performed the Timed Up & Go (TUG) and Five Times Sit-to-Stand (FTSST) tests . Results: Increased age affected improvements in the TUG results (p=0.017). The type, intensity and duration of physical activity did not correlate with pain, function or quality of life improvements (p>0.05), but the TUG results were on average 4 seconds faster among the patients who practiced intense physical activity and/or exercised for more than 180 minutes per week and/or performed isolated weight training or swam compared with those who remained sedentary after 2 years (p=0.01; p<0.001; p=0.01; p=0.04, respectively) . Conclusions: Patients with KOA should aim for intense physical activity and/or more than 180 minutes of exercise per week and/or weight training (bodybuilding) for relevant pain reduction and functional improvement.

INTRODUÇÃO: A saúde reprodutora masculina pode ser influenciada devida à prática de atividade física, e com isso tem-se aumentado o número de estudos que analisam o efeito da atividade física na qualidade seminal. Descobertas apontam que mudanças significativas na qualidade do sêmen podem ocorrer com a prática de atividade física, que pode alterar sua qualidade de acordo com o tipo de atividade física, a intensidade e a duração. OBJETIVO: Neste contexto, o presente estudo realizou uma análise detalhada da literatura atual com o objetivo de verificar o efeito de diferentes atividades físicas sobre a saúde reprodutora masculina. MÉTODO: Trata-se de uma revisão sistemática feita nas bases de dados do PubMed. Utilizou-se os itens propostos pelo PRISMA para a busca, seleção e extração de dados. De acordo com o fluxograma proposto, 244 artigos foram identificados e, destes, 12 foram selecionados. RESULTADOS: Apoiada por fortes evidências clínicas, esta revisão sugere que a atividade física intensa pode provocar fortes alterações hormonais e prejudicar a qualidade seminal. Já a atividade física moderada parece ter um efeito neutro ou benéfico para a qualidade do sêmen. Além disso, o efeito da atividade física na qualidade do sêmen pode ser diferente de acordo com o tipo de atividade física. CONCLUSÃO: Frente às evidências, ainda existe falta de conclusões sólidas sobre esse assunto, devido ao fato de existir muita contradição entre os estudos existentes e da atividade física não ser facilmente quantificada. ABSTRACT. Effect of physical activity on seminal quality, BACKGROUND: Male reproductive health may be influenced by physical activity, and this has increased the number of studies that analyze the effect of physical activity on seminal quality. Findings indicate that significant changes in semen quality can occur due to the practice of physical activity, which can alter its quality according to the type of physical activity, intensity and duration. OBJECTIVE: In this context, the present study performed a detailed analysis of the current literature with the objective of verifying the effect of different physical activity on male reproductive health. METHODS: A systematic review performed on the PubMed databases. The items proposed by PRISMA were used for searching, selecting and extracting data. According to the proposed flowchart, 244 articles were indentified and, of these, 12 were selected. RESULTS: Supported by strong clinical evidence, this review shows that intense physical activity can cause strong hormonal changes and impair seminal quality. On the other hand, moderate physical activity seems to have a neutral or beneficial effect on semen quality. In addition, the effect of physical activity on semen quality may differ according to the type of physical activity. CONCLUSION: Faced with the evidence, there is still a lack of solid conclusions on this subject, due to the fact that there is a lot of contradiction between the existing studies and that physical activity can not be easily quantified.

Estimating the factors affecting participation decisions of physical activity has continuously received significant research attention. However, the effects of income and demographic factors on physical activity intensity have seldom been studied thoroughly, especially in developing countries. To fill this research gap, the income and demographic determinants of the time spent on both vigorous- and moderate-intense physical activities among Malaysian adults are estimated using a censored regression model. The results are comparable to those in developed countries, such as the USA and Australia, which show that income, age, education level and being unemployed are negatively associated with the time spent on both vigorous- and moderate-intense physical activities. Compared to females, males spend more time on vigorous-intense physical activity but less time on moderate-intense physical activity. The present study suggests that acquiring a better understanding of the factors that can affect physical activity intensity is important for policy development. JEL Classification: D01, I10, I12
