| Research Abstract |
In healthy but sedentary young women, postprandial, but not shortly preprandial, moderate(50% VO2max, 30 min) aerobic exercise reduced the number of intestinally derived lipoproteins and improved the exogenous lipoprotein metabolism, suggesting that postprandial exercise is more effective for improving the postprandial lipoprotein metabolism than shortly preprandial exercise. Although postprandial aerobic exercise alleviated the glycemic peak associated with insulin' sparing' after the simultaneous ingestion of glucose and fat, the effect of exercise on fat metabolism was transient, enhancing the secretion of intestinal lipoproteins at an early phase. Simultaneous ingestion of glucose and fat mimicked the postprandial metabolism after the ingestion of cookies. Moreover, four weeks of moderate aerobic exercise training improved antioxidant status and lipoprotein metabolism, particularly postprandial metabolism, in sedentary but otherwise healthy young women.
