Effect of Exercise on Metabolic Health
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Insulin Sensitivity [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)
Secondary Outcome Measures
- Resting Metabolic Rate [20-30 min]
- Meal Tolerance Test [3 hours]
Eligibility Criteria

Exclusion Criteria:
- pregnancy or actively breastfeeding, weight instability (> or = to ± 5 lbs in the past month) evidence of cardiovascular or metabolic diseases, taking medications know to affect lipid and/or glucose metabolism.
