We aimed to identify whether racial differences in body composition and glucose metabolism occur in response to exercise and determine whether aerobic and resistance exercise modalities bring about differential changes in these parameters in African Americans and White persons with type 2 diabetes. Participants included 36 African American and 23 White men and women with type 2 diabetes who were randomly assigned to eight weeks of either resistance or aerobic exercise. Before and after this intervention, each participant underwent a series of measurements that assessed anthropometrics and glucose metabolism. African Americans responded more favorably to resistance training than did Whites. This difference was manifested by a significant improvement in BMI (-2.57%+/-.90% vs 2.57%+/-1.09%, P
