The microdamage of rabbit patellar tendon under static tensile load was detected by AE technique. The damage process of intact and injured tendon was successfully monitored. It was found that the higher amplitude AE signals were detected before the maximum stress under the higher loading rate. It was then suggested that larger scale of microdamages, such as bundles of fibers, ruptured simultaneously under the higher loading rate. AE source location was corresponded with the area where the local strain increased. Consequently, the fundamental insights for the damage monitoring technique which are indispensable for the optimization of programs of sports training or rehabilitation are obtained.

通过AE技术检测到静态拉伸负荷下的兔tellar肌腱的微塑料。完整和受伤的肌腱的损伤过程得到了成功监测。发现在较高的加载速率下最大应力之前检测到较高的振幅AE信号。然后建议，在较高的负载速率下同时破裂的较大的微型造影剂（例如纤维束）。 AE源位置与局部应变增加的区域相对应。因此，获得了损害监测技术的基本见解，这对于优化运动训练或康复计划是必不可少的。
