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.

Experimental: Exercise

Other: Exercise
single session of exercise

No Intervention: Sedentary Control

Outcome Measures

Primary Outcome Measures

  1. 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

  1. Resting Metabolic Rate [20-30 min]

  2. Meal Tolerance Test [3 hours]
