African Americans are at a substantially greater type 2 diabetes risk compared to Caucasians;
however, very little data are available on the effects of exercise training on type 2
diabetes risk factors in at risk African Americans. The present proposal will evaluate the
effects of 6 months of moderate versus vigorous intensity aerobic exercise training on
fitness, insulin sensitivity, mitochondrial capacity, skeletal muscle oxidative/insulin
sensitivity markers, adiposity, and quality of life in African Americans.
