| 摘 要： | 为探讨不同强度跑台运动对老年机体内血浆内皮素-1（ET-1）水平的影响，以18月龄大鼠为研究对象，随机分为4组：大强度运动组、中等强度运动组、小强度运动组、增龄对照组，另设3月龄对照组．运动组的运动方式为跑台运动，共训练6周，观察增龄和不同强度跑台运动对大鼠血浆ET-1及血清MDA、SOD水平的影响。结果显示：增龄大鼠血浆ET-1、血清MDA水平与青年对照组相比显著升高，而血清SOD水平显著下降。经过为期6周的跑台运动，中等强度运动组增龄大鼠血浆ET-1、血清MDA水平显著下降，SOD活性显著增强，而强度过大或过小的运动训练则对其无显著性影响。

| Abstract: | The purpose of this paper is to investigate the effect of running with different workload on plasma ET-1 in aging old rats.The rats of 18 months old were used as the subjects of the study and were randomly divided into 4 group:high intensity exercise group,middle intensity exercise group,low intensity exercise group,old control group and yang control group.The exercise group had their running training for 6 weeks.Effects of aging and running with different workload on plasma ET-1,serum SOD and MDA were obse... |
