骨骼肌作为运动员从事体育运动的动力器官,长期以来一直是体育科学研究中的一个重要领域。近几十年来,随着对骨骼肌研究的不断深入,人们不但丰富厂对骨骼肌形态、结构、机能等特征的认识,而且在骨骼肌纤维的组成与运动能力的关系方面做了大量的工作。国内外学者认为,人体骨骼肌纤维组成与所从事的运动项目有密切的关系,而且已成为运动员获得某些项目优异成绩的先决条件之一。因此,研究并运用这一关系进行科学选才,有的 Skeletal muscle as a sports organ in which athletes engage in sports has long been an important field in sports science. In recent decades, with the deepening of research on skeletal muscle, people not only enrich the plant’s understanding of the characteristics of skeletal muscle morphology, structure and function, but also do a great deal of work on the relationship between skeletal muscle fiber composition and exercise capacity. Domestic and foreign scholars believe that the composition of human skeletal muscle fibers and sports are engaged in a close relationship, and has become one of the prerequisites for athletes to obtain outstanding results of some projects. Therefore, the study and use of this relationship for scientific selection, and some
