What role does physical activity have in maintaining fitness and a healthy body weight?
Physical inactivity has contributed to the growing rates of obesity—most worrisome are rates among children and adolescents. Inactivity has been studied extensively in this age group (television viewing, video games, and computers). This trend is changing and opportunities to increase physical activity are increasing. New physical activity recommendations for adults released by the U.S. government recommend that adults engage in at least 150 minutes/week of moderate-intensity or 75 minutes/week of vigorous-intensity aerobic activity, plus moderate- or vigorous-intensity muscle-strengthening activities on 2 or more days/week. According to an International Association for the Study of Obesity expert panel, daily exercise assists in prevention of weight gain among adults.
