  Purpose
It is hypothesized that the patients in the EXDA group will be able to complete a structured exercise program at a level sufficient to accumulate at least 2000 kcal per week, and that the structured endurance activity will increase their physical fitness and total daily energy expenditure compared to the DA group.
