Acute effects of mild exercise on postprandial glucose and unsulin responses

Abstract

Purpose: Hyperinsulinemia is a risk factor for cardiovascular disease. Chronic exercise is established as an anti-hyperinsulinemic factor. The purpose of this study was to determine if a postprandial exercise bout (20 min walk at 70% ventilatory threshold) could reduce the insulin response to a standard meal. Method: Healthy volunteers (n = 1 1) consumed a meal (982 kilocalories, 29 grams protein, 140 grams carbohydrates, 34 grams fat) on two separate days. Glucose Ad insulin responses were followed for 2 hours, while the subjects either rested (Control) or performed mild exercise (Exercise) between 30-50 minutes postprandial. The order of Control and Exercise was random.
