Study Arms (2)

dietary, and aerobic exercise

ACTIVE COMPARATOR

Intervention for diet-A hypocaloric diet will be developed to achieve a 2800 kcal/week deficit, which should produce about 0.4 kg (1 lb.) weight loss per week. Intervention for aerobic exercise-Based on initial evaluations and the stress testing results, (HR, VO2, RPE) an individual exercise prescription will be developed for aerobic training.

Behavioral: dietary, and aerobic exercise
