RESUMO
The prescription of exercise is particularly useful for preventing premature death from all causes, ischemic heart disease, stroke, hypertension, colon and breast cancer, type 2 diabetes, metabolic syndrome, obesity, osteoporosis, sarcopenia, functional dependence and falls in the elderly, cognitive impairment, anxiety and depression. This benefit is observed in both sexes and increases with the volume or intensity of exercise. These benefits are obtained through moderate aerobic exercise for at least 30 minutes 5 days per week or vigorous exercise for at least 20 minutes 3 days a week. It is recommended to add a minimum of 2 nonconsecutive days, each week, to practice 8-10 exercises that develop the strength of most muscle groups (arms, shoulders, chest, abdomen, back, hips and legs). It is also advisable to spend 2 sessions of 10 minutes per week to practice 8-10 exercises that maintain the flexibility of most groups of muscles and tendons. The exercise may involve musculoskeletal injuries and cardiovascular risk, but the benefit outweighs the risk.
