应用直接和间接计数法计算人的右侧腓肠肌外侧浅亚部所含的肌纤维数量。在直接计数法中,将肌横切面的切片在显微镜下行重叠连续照相,照片放大后,裁去重叠部分,再拼接成全部切片的放大图,直接计数肌纤维总数和两型肌纤维的构成比。间接计数法以抽样法摄取部分切面进行计数,再通过测量切片总面积 The direct and indirect counting method was used to calculate the number of myofibers contained in the light subsets of the right lateral gastrocnemius. In the direct counting method, the sections of muscle cross-sections are continuously photographed under a microscope. After the photos are enlarged, the overlapping portions are cut out and then spliced ​​into an enlarged view of the whole sections to directly count the total number of the muscle fibers and the composition ratio of the two types of muscle fibers. Indirect counting method Sampling method to take part of the section count, and then by measuring the total area of ​​the slice
