人类骨骼肌的肌纤维型在形态、生理性质和酶组织化学特性方面都有明显差异,据此可将肌纤维分为不同的类型。骨骼肌纤维型的研究在骨骼肌的结构与功能相关的问题上开辟了一个新的领域,可直接服务于体育训练和运动员选才;比较人类与动物肌纤型比例分布的差异,可以窥见人类进化的轨迹;比较种族之间和个体之间的差异,于人种学和遗传学均有重要意义。近年来,病理学已发现某些肌病选 Muscle fiber types of human skeletal muscle in the morphological, physiological properties and enzymatic histochemical characteristics are significantly different, according to which the muscle fibers can be divided into different types. The study of skeletal muscle fiber type has opened up a new field in the structure and function related issues of skeletal muscle, which can directly serve sports training and selection of athletes. Comparing the differences in the proportion distribution of muscle fibers of human beings and animals can reveal human evolution The comparison of race and individual differences is of great importance in ethnography and genetics. In recent years, pathology has found some myopathy options
