| （苏州大学 体育学院，江苏 苏州 215021） 摘 要：肌腱作为骨与肌肉的关联纽带，在运动训练中具有重要的作用，肌腱疲劳与其生物力学性能密切相关。疲劳实验时肌腱达到断裂所需的时间或循环拉伸的次数与作用的应力和（或）应变及频率大小、标本的长度、温度等有一定关系，高应力肌腱疲劳性高于低应力肌腱。在一定的范围内，肌腱的疲劳性与其所承受的应力相适应，适宜运动刺激可通过力学性能的改变提高其疲劳性。 |

Tendon fa-tigue is closely related to its biomechanical properties. In fatigue experiment, there is a certain relation between the time required for a tendon to rapture or the number of times of circulative tension and the acting stress and/or strain as well as frequency magnitude, specimen length and temperature; a high stress tendon is easier to fatigue than a low stress tendon. Within a certain extent, the fatigue of a tendon is in accord with the stress it is subjected to; ap-propriate kinetic stimulation can improve its fatigue condition via the change of mechanical properties. |
