Research study analyzes best exercise for obese youths

What exercise program can best fight the “epidemic” of teen obesity? According to a study published in the Journal of the American Medical Association (JAMA) Pediatrics, by combining aerobic exercise with resistance training.

The Healthy Eating Aerobic and Resistance Training in Youth (HEARTY) study, led by researchers at the University of Calgary and University of Ottawa, involved 304 overweight teens in the Ottawa/Gatineau area between the ages of 14 to 18. All were given the same four weeks of diet counseling to promote healthy eating and weight loss before being randomly placed into four groups. The first group performed resistance training involving weight machines and some free weights; the second performed only aerobic exercise on treadmills, elliptical machines and stationary bikes; the third underwent combined aerobic and resistance training; and the last group did no exercise training.

“Obesity is an epidemic among youth,” says Dr. Ron Sigal of the University of Calgary’s O'Brien Institute for Public Health and Libin Cardiovascular Institute of Alberta. “Adolescents who are overweight are typically advised to exercise more, but there is limited evidence on what type of exercise is best in order to lose fat.”
