Measure
Exercise Training
Based on initial evaluations and the stress testing results, (HR(heart rate), VO2(maximal volume of oxygen that the body can deliver to the working muscles per minute), RPE(rate perceived exertion) an individualized exercise prescription will be developed for each subject. Exercise: walking, treadmill and bicycle exercise
Dietary Intervention
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. Dietary Intervention: Subjects will be provided meals and instructions for individual food selections.
Attention Control
Attention control participants will be provided a counseling session regarding general health education at baseline and will be contacted by staff via telephone every 2 weeks to discuss general health status. Attention Control: control group- continue their previously randomized life style
Diet and Exercise
The diet and exercise group is a combination of the two groups previously described. Exercise: walking, treadmill and bicycle exercise Diet and exercise: Combination of the exercise and diet group as previously described.
