运动与动脉管壁的弹性

Physical Exercise and the Elasticity of Arterial Walls

以219名年青运动员,41名老年长跑锻炼者及15例,不从事锻炼的老年脑力劳动者为研究对象,分别测定安静状态下动脉波传导速度。研究结果表明,随着年龄的增长,传导速度逐渐延长;老年长跑者比不参加锻炼的脑力劳动者及一般健康人动脉波传导速度均有显著差异,提示体育锻炼对保持血管壁的弹性有良好作用。

219 young athletes, 41 long distance runners of old age and 15 sedentary people have beenstudied. The method of non-invasive arteriography was adopted to determine arteria wave trans-mitting speeds at a state of rest. The results showed that the transmitting speed increased in pro-portion to age. Although there were significant differences among age groups above 50, no signifi-cant differences were found among the young athletes. The arterial speed in long-distance runnersbetween 50 and 60 years of age was found to be slower than that in sedentary people. This indi- cated that long- distance running could help retard the loss of elasticity of the arterial walls inthe aged.
