Effect of Exercise on Metabolic Health

March 18, 2022 updated by: Jeffrey F Horowitz, University of Michigan

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Insulin Sensitivity
Time Frame: 2-3 hours
A hyperinsulinemic-euglycemic clamp will be used to assess peripheral insulin sensitivity. Insulin sensitivity will be calculated from the clamp data as the rate of glucose infusion during the steady state period of the clamp - divided by the plasma insulin concentration at this time (units: mg/uU/ml/min)
2-3 hours

Secondary Outcome Measures

Outcome Measure
Time Frame
Resting Metabolic Rate
Time Frame: 20-30 min
20-30 min
Meal Tolerance Test
Time Frame: 3 hours
3 hours
