运动与血管紧张素Ⅱ

Sports and Angiotensin Ⅱ

血管管系统存在局部肾素——血管紧张素系统(RAS),可自身合成、释放血管紧张素Ⅱ(Ang Ⅱ),在高血压,心肌缺血、心肌肥大等疾病的发生上具有重要作用。总结AngⅡ的机制及作用,并对运动与AngⅡ的关系进行综述,寻找运动中血浆AngⅡ导致损伤发生的阈值,是一个值得研究的问题。

There is a partial rennin-angiotensin system (RAS) in the cardiovascular system. It is able to synthesize, release angiotensin Ⅱ(AngⅡ), and it is one of the most important factors related to some diseases, such as the hypertension, myocardial ischemia and hypertrophy, etc. In this paper the mechanism and the effects of the Ang Ⅱ are reviewed. And the relations between sports and AngⅡ are also reviewed. We can infer that during exercise AngⅡin the blood plasma may cause injury and AngⅡ threshold may be worth to be studied.
