The most marked changes in the human muscle following tendinous injury can be observed in the contractile components. There is a widening of the Z-membrane, dispersion of the sarcomers, a break in their continuity, and detached bundles of myofibrils are found in the sarcoplasm. A change occurs also in the proportion of different fibre types of the muscles, in the muscle with tendinous injury a predominance of type II fibre becoming apparent. Among the proteins of myofibrils a product of disintegration of a molecular weight of 31 000 can be consequently demonstrated, and in some muscles products of disintegration with a molecular weight between 90 000 and 58,000 arise.
肌腱损伤后，人体肌肉中最显著的变化可在收缩成分中观察到。Z膜增宽，肌节分散，其连续性中断，肌浆中可见分离的肌原纤维束。肌肉中不同纤维类型的比例也会发生变化，在有肌腱损伤的肌肉中，II型纤维占优势变得明显。因此，在肌原纤维蛋白中可证实有一种分子量为31000的分解产物，在某些肌肉中还会出现分子量在90000至58000之间的分解产物。
