In the past 30 years, obesity rates for children have doubled, and the rates for adolescents have tripled. A combination of diet and exercise has long been established as a sound approach to weight loss, and a new study published online by the American Journal of Physiology-Endocrinology and Metabolism offers suggestions for boys and girls age 12 to 18 years.
Researchers had 44 adolescent girls perform aerobic exercise for an hour per session 3 days a week using either the treadmill or elliptical machine. Other subjects performed 10 upper and lower body weight training exercises for an hour. After 3 months, both groups lost fat mass, but the aerobic effort produced better overall results.
Coincidentally, girls preferred aerobic training to weight lifting while a similar group of adolescent boys preferred weight training over cardio conditioning. Engaging in both types of exercise might round out your overall level of fitness while contributing to muscle gains -- especially if you're watching what you eat.
