Abstract:
Objective To determine the influence of aerobic exercise on advanced glycation end products (AGEs)in plasma using a rat model of type 2 diabetes,and to provide an experimental basis for explaining the rehabilitative mechanism of aerobic exercise in type 2 diabetes.Methods Fifty-two healthy 8-week-old male SpragueDawley rats were allocated at random into a normal control group(n=10)and a type 2 diabetes model group(n=42).The latter were overfed with a high-sugar,high-fat and high-energy diet for 4 weeks,then 30ms/kg of streptozotocin was injected intraperitoneally to create a model of type 2 diabetes.Thirty diabetic rats were then allocated at random into a diabetes control group,a low intensity exercise group and a moderate intensity exercise group with 10 in each group.The treadmill exercise was administered to the animals in the low and moderate exercise groups accordingly.Results Compared with the normal control group,plasma AGEs increased significantly in the diabetes control and moderate intensity exercise groups.Compared with the diabetes control group,AGEs in the lower intensity exercise group were significantly lower.Compared with the moderate intensity exercise group,plasma AGEs in the low intensity exercise group were somewhat lower,but not significantly.Conclusion Aerobic exercise can reduce plasma AGE levels in rats with a model of type 2 diabetes.The effect is probably related to decreasing excessive blood glncose and the exercise intensity.
