Do antioxidant vitamins ameliorate the beneficial effects of exercise training on insulin sensitivity?

摘要

PURPOSE: Exercise training has numerous health benefits, and in patients with type 2 diabetes mellitus and metabolic syndrome, it can improve insulin sensitivity and glucose control. A recent publication suggests that antioxidant vitamins (C and E) block these effects on blood glucose. This investigation was undertaken to determine whether antioxidant vitamins ameliorate the beneficial effects of cardiac rehabilitation and exercise training (CRET) on insulin sensitivity and glucose metabolism in patients with coronary heart disease (CHD).
