William J. Evans, Ph.D. is a Professor and the Director of the Nutrition, Metabolism and Exercise Laboratory in the Donald W. Reynolds Department of Geriatrics. Dr. Evans was chosen by NASA to be the team leader for nutrition, physical fitness, and rehabiliation as part of NASA’s intramural program. Some research projects being conducted as part of this program include: the effects of a high carbohydrate, ad libitum diet and aerobic exercise on insulin action and muscle metabolism; effects of megestrol acetate (megace), testosterone, and strength training on food intake, body composition, functional capacity, and metabolism in underweight older men; effects of short-term weight loss on insulin action in overweight older women; influence of resistance, exercise and age on muscle protein degradation; and effects of resistance training, dietary protein requirements of elderly men and women. UAMS is one of 13 medical schools in the nation conducting research in the intramural NASA program.
