Active Comparator: 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.
walking, treadmill and bicycle exercise
Active Comparator: 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 Supplement: Dietary Intervention
Subjects will be provided meals and instructions for individual food selections.
Active Comparator: 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.
Other: Attention Control
control group- continue their previously randomized life style
Active Comparator: Diet and Exercise
The diet and exercise group is a combination of the two groups previously described.
walking, treadmill and bicycle exerciseBehavioral: Diet and exercise
Combination of the exercise and diet group as previously described.
- Exercise capacity [ Time Frame: 20 weeks ]
- Body and thigh muscle composition, Quality of Life [ Time Frame: 20 weeks ]
