蛋白质分解代谢在运动中的变化及作用已引起国内外研究者的广泛关注.据文献资料报导,运动中蛋白质分解供能约占5～10%,以弥补糖元供能的不足.蛋白质是细胞的主要组成成分,对于组织的生长、修复起着极为重要的作用.运动中蛋白质分解增强可致人体内蛋白质总量丢失,长期运动训练时不注意蛋白质的补充,氮利用势必增加,可能引起人体疲劳.由于运动中蛋白质代谢的变化较为复杂,且选用的评定指标各异,研究结果存在一些矛盾,有必要进一步深入研究.本文根据已获得的文献作一综述.
Protein catabolism in the movement of the changes and the role has attracted widespread attention of researchers at home and abroad.According to the literature, the exercise of proteolytic energy for about 5 ~ 10%, to make up for lack of glycogen energy.Protein is the cell Of the main components of the organization for the growth and repair plays an extremely important role in the exercise of protein decomposition can cause the body to lose the total amount of protein, long-term exercise training do not pay attention to protein supplements, nitrogen use is bound to increase, may cause the human body Fatigue.Due to the complicated changes of protein metabolism in exercise and the different evaluation indexes, there are some contradictions in the research results and it is necessary to further study.This article is based on the literature obtained.
