We hypothesize that improvement in cardiovascular fitness is associated with a greater improvement in insulin sensitivity than improvement in body composition (loss of body fat) is associated with insulin sensitivity. Towards that we are randomizing children who are overweight, or children with low fitness levels to exercise intervention 2 or three times per week.
