What are the current recommendations for adolescents regarding physical activity and what are the benefits of regular physical activity?
The Physical Activity Guidelines for Americans recommends that all adolescents be physically active daily, or nearly every day, as part of play, games, sports, work, transportation, recreation, physical education, or health promotion. Further, they recommended that adolescents engage in muscle- and bone-strengthening activities at least three days per week. Regular physical activity improves aerobic endurance and muscular strength, may reduce the risk of developing obesity, and builds bone mass density. Physical activity among adolescents is consistently related to higher levels of self-esteem and self-concept and lower levels of anxiety and stress.
