Effect of Exercise on Metabolic Health

Effect of Exercise on Novel Insulin Signaling Events in Human Muscle

One of the main objectives of this study will be to assess potential differences in important risk factors associated with Metabolic Syndrome in overweight adults who do not participate in a regular exercise program compared with overweight individuals who do exercise regularly. In addition, we will determine the effects of a single, modest session of exercise on the body's ability to control blood sugar and regulate fat metabolism in obese sedentary adults vs. obese adults who live a physically active lifestyle. Our study focuses on identifying mechanisms responsible for improved insulin action related to regular exercise and to provide novel targets for preventing and treating type 2 diabetes.
