Muscle Lipid and Insulin Resistance in the Elderly

This project will provide novel information concerning the ability of exercise to enhance the capacity for oxidative metabolism of fatty acids and improve insulin resistance in older adults who are at high risk for the development of type 2 diabetes. Ultimately this may help identify mechanisms and therapeutic targets implicated in skeletal muscle metabolic dysregulation. The proposed study is to conduct a randomized controlled exercise training intervention trial in older men and women. In addition, the response to exercise in these subjects will be compared to those of highly endurance-trained, age-matched athletes.
