本研究的目的,是测量划艇和皮船的优秀划船运动员的肌纤维类型、等速性肌力以及疲劳(耐力)。受试者是9名划艇和皮船的优秀划船运动员(男子5名、女子4名),其中6名是世界锦标赛前10名、2名是世界冠军。年龄平均是24.6岁,身长是172.7cm,体重是75.5kg。肌肉活组织检查在股外肌和肱二头肌处进行。肌肉取样进行三磷酸腺苷酶(ATPase)染色,被分成ST、FTa、ETb。另外,肌纤维面积通过测量直径来
The purpose of this study was to measure the type of muscle fibers, isokinetic muscle strength, and fatigue (endurance) of rowers and kayak elite rowers. The participants were nine rowers (four men and four women) for rowing and kayaking, of which six were the top 10 of the world championships and two were world champions. The average age is 24.6 years old, length is 172.7cm, weight is 75.5kg. Muscle biopsies were performed at the femoral and biceps muscles. Muscle samples were subjected to ATPase staining and were divided into ST, FTa and ETb. In addition, muscle fiber area by measuring the diameter
