运动对24小时动态血压的影响

The Effects of Exercise on 24-hour Ambulatory Blood Pressure

综述了近年来国内外有关运动对24小时动态血压的影响研究,结果显示一次性运动后会导致血压在一定时间内下降(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 researches home and abroad on the effects of exercise on 24-hour ambulatory blood pressure and draws the conclusion that after an acute exercise blood pressure level reduces within a certain period of time for up to 22 hours,and can even be lower than the control level （e.g.post-exercise hypotension）.On the other hand the chronic aerobic exercises at modest intensity have better effects on reducing 24-hour 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 structure and responsiveness,body weight losing and decrease of insulin resistance and so on.
