谷氨酰胺对运动机体的影响

On Effects of Glutamine on Exercise Mechanics

谷氨酰胺是人体内重要的氨基酸,与运动能力有密切的联系。机体运动对谷氨酰胺代谢的影响与运动持续时间、运动强度、运动方式等因素有关,短时间运动能使血浆谷氨酰胺浓度升高,长时间耐力运动则使之含量下降。长时间耐力性运动导致的血浆谷氨酰胺含量的降低可能引起耐力运动中蛋白质分解代谢失常、氨转运清除率下降以及运动后机体免疫功能下降等。

Since glutamine is one of the most important amino acids in one＇s body, it is closely concerned with one＇s exercise power. And the effects of exercise mechanics on glutamine involve some factors such as the duration of exercise, the intensity of exercise and the modes of exercise, etc.. This paper suggests the short period of exersice can induce a rise in the amount of glutamine of one＇s body while the durable exersice can have a fall in that, which is very likely to cause some results such as the unbalanced metablism of proteolysis and the decrease in the clearance rate of the glutamine transformation and in the immunecompetence after exercise as well.
