大部分的韧带和肌肉是支撑起整个身体重量的一部分，特别在剧烈的运动中，例如跳高，或者马拉松比赛。

Most of the ligaments and muscles that are part of it create the right static to hold all the body weight even at abrupt movements like, for example, after a jump or during long efforts at a marathon.

例如，肺部和心脏肌肉扩张不太成功，血管变得越来越僵硬，韧带和肌腱收紧。

For example, the lungs and the heart muscle expand less successfully, the blood vessels become increasingly rigid, and the ligaments and tendons tighten.
