探讨抗阻运动对老年人动脉硬化和血管内皮功能的影响。选取24名健康无规律运动史的老年男性，并随机分为运动组和对照组，每组12人，运动组进行12周的抗阻运动，对照组保持原有生活习惯不变。实验前后分别测定两组受试者血浆NO、ET-1和BaPWV的变化。结果运动组实验后血浆NO水平明显高于实验前和对照组，血浆ET-1水平没有明显变化，且BaPWV未见明显增加。本实验证明抗阻运动对老年人血管内皮功能产生良好的影响，且不会使动脉弹性变硬，这对于制定老年人预防心血管疾病的运动处方具有重要意义。%The paper investigated the effect of resistance exercise on atherosclerosis and vascular endothelial function on the elderly. Selected 24 older men who were divided into exercise group and control group at random,there being 12 men in each group. The one in exercise group did resistance movement for 12 weeks, while the control group keeping the original living habits unchanged at the same time. The plasma levels of NO,ET-1,BaPWV in two groups were measured before and after the experiment. After 12 weeks,the plasma NO level of exercise group was significantly higher than the original one,the level of ET-1 in plasma did not change obviously,and BaPWV was not significantly increased either. This experiment proved that resistance training in older adults could produce beneficial effects on the vasculature and there were not any unfavourable effects,it was great significant for the developing of the exercise prescription of the prevention of cardiovascular disease in the elderly.
