Participating in physical activity is important for children and teens as it may have beneficial effects not only on body weight, but also on blood pressure and bone strength.
Children may be spending less time engaged in physical activity during school.
The U.S. Department of Health and Human Services/U.S. Department of Agriculture Dietary Guidelines for Americans recommend that children and teens be physically active for at least 60 minutes on most, if not all, days.
