运动对24小时动态血压的影响

Effects of exercise on 24 hours ambulatory blood pressure

采用文献资料法综述近年来国内外有关运动对24小时动态血压的影响的研究表明,一次性运动后会导致血压在一定时间下降(可持续22小时),有时甚至低于对照水平(运动后低血压),长期进行中等强度的有氧运动对血压正常者或高血压患者24小时的动态血压具有较好的降压效果。遗传、神经体液因素的改变、血管结构及血管反应性的改变、体重降低以及胰岛素抵抗的降低等都可部分解释运动的降压作用。

This paper reviews the recent articles on the effects of exercise on 24 hours ambulatory blood pressuer and draws the conclusions that blood pressure reduces for up to 22 hours after an acute exercise, and even lower than that of the control level （e. g. postexercise hypotension）. On the other hand, the chronic aerobic exercises at modest intensity have better effects on reducing 24 hours ambulatory blood pressure for subjects with normal blood pressure or hypertension. The proposed mechanisms for the blood pressure lowering effects of exercise include genetic influences, neurohumoral factors, vascular strcture and responsiveness, body weight losing and insulin resistance decreasing and so on.
