This project aims to examine what sort of forceful stretch is required to cause exercise induced muscle damage (EIMD) in humans and how muscles adapt to limit future damage. Specifically, the project aims to examine how the elastic properties of tendons might reduce muscle damage by buffering stretch in muscle fibres. Using cutting-edge ultrasound imaging technology, human muscle strain in different regions of muscle will be examined to quantify the temporal relationship between muscle power absorption and EIMD. The importance of muscle and tendon mechanical properties in buffering the muscle from potential damage will be gauged. This could be a critical mechanism for preventing EIMD in exercising humans.

该项目旨在研究什么样的强力拉伸才能导致人类的运动性肌肉损伤(EIMD)，以及肌肉如何适应以限制未来的损伤。具体地说，该项目旨在研究肌腱的弹性特性如何通过缓冲肌肉纤维中的拉伸来减少肌肉损伤。利用尖端超声成像技术，将检测肌肉不同区域的肌肉应变，以量化肌肉功率吸收与EIMD之间的时间关系。肌肉和肌腱的机械性能在缓冲肌肉免受潜在损伤方面的重要性将被测量。这可能是预防人类运动中EIMD的关键机制。
