这样子加强了新的肌肉和结缔组织，同时减少同一部位的重复应力。

This strengthens new muscles and connective tissues while reducing the repetitive stress on the same body parts.

结论：跟腱力学性质的变化是对重复应力刺激的一种反应，是肌腱对抗力学疲劳的机制。

Conclusion: The increase in mechanical properties may be a response to repeated stress and may function as a mechanism to resist tendon damage due to mechanical fatigue.

苏格兰工程师和热力学创始人之一的威廉·兰金(William Rankine)是第一个解释这些重复的应力反向如何能够导致裂缝蔓延。

William Rankine, a Scottish engineer and one of the fathers of thermodynamics, was the first to explain how these repeated stress reversals could cause cracks to propagate.
