Physical activity, exercise, and sedentary activity: relationship to the causes and treatment of obesity.

Lack of physical activity is a known determinant of obesity. Unfortunately, children become less and less active as they reach and progress through adolescence. This behavior leads to detrimental effects on body composition and other components of health-related physical fitness. Various types of exercise and activities have different effects on fitness, body composition, and metabolic state. For a physician to recommend activities or sports and exercise type, he or she should examine and discuss the patients fitness and physique goals to maintain their enthusiasm and promote lifelong physical activity benefits.
