本实验对六名竞技健美操运动员进行了六个月的训练跟踪。结果发现,运动员三角肌纤维类型百分比训练前后无显著变化;慢肌纤维横断面积训练后较训练前平均增加35%;快肌纤维横断面积平均增加18%。反映骨骼肌细胞代谢状况的酶活性珀琥酸脱氢酶,训练后较训练前平均增加54.5%(P<0.05)。细胞色素氧化酶训练后较训练前平均增加44.2%,乳酸脱氢酶训练前后无显著变化。 The experiment of six athletic aerobics athletes conducted a six-month training track. The results showed that there was no significant difference in the percentage of deltoid muscle types before and after training. The average cross-sectional area of ​​slow muscle fibers increased by 35% after training and the average cross-sectional area of ​​fast fibers increased by 18%. Enzyme activity succinate dehydrogenase, which reflects the metabolic status of skeletal muscle cells, increased by 54.5% (P <0.05) on average after training. Cytochrome oxidase training than before training an average increase of 44.2%, lactate dehydrogenase training before and after no significant change.
