在威斯特鼠的实验中,10小时游泳引起四头肌白肌中3—甲基组氨酸和游离酪酸含量的即时增加。而在红肌中这一增加发生在运动后恢复的6～48小时间。红肌中糖元的减少非常显著,表明运动中最活性的是氧化糖酵解纤维中,总之,运动中最具活性的肌纤维不引起蛋白质的动员,在运动后恢复的后一阶段,分解代谢的变化发生在最具活性的纤维中,构成了部分蛋白转换增加。
In a Westphalian experiment, a 10-hour swim resulted in an immediate increase in the content of 3-methylhistidine and free butyric acid in the tetrakis muscle. This increase in red muscle occurs 6 to 48 hours after exercise. The decrease of glycogen in red muscle is very significant, indicating that the most active in exercise is in oxidized glycolysis fiber. In short, the most active muscle fiber in exercise does not cause the mobilization of protein. In the latter stage of recovery after exercise, catabolism The changes occur in the most active fibers, which constitute part of the protein conversion increase.
