| 摘 要： | 阐述了运动性疲劳的含义、主要表现、发生的机理,及神经递质的确定条件和主要类型以及研究意义,总结了运动对5-HT代谢及浓度变化的影响以及此种影响对疲劳的作用的研究现状:1.长时间运动促进了脂肪酸的动员和支链氨基酸供能,从而提高了血浆中游离色氨酸的浓度。2.5-HT不能通过血脑屏障,而游离色氨酸可以通过血脑屏障。3.色氨酸是5-HT的合成前体。4.5-HT是一种抑制性神经递质。5.不管是长时间耐力运动还是急性剧烈运动都能引起大脑中5-HT浓度的升高。6.疲劳时5-HT浓度最高。7.5-HT引起中枢疲劳的神经通路和可能的机理。8.药物介导显示5-HT浓度升高,疲劳加剧。9.补充支链氨基酸对延长运动时间有意义。10.运动训练可以提高机体对5-HT浓度变化的适应。

| Abstract: | This study described the meaning of exercise fatigue、appearance expression、generate mechanism and the assured factors,types of neurotransmitter,at the same time,summarized the affection of metabolism and concentration changed by exercise,and introduced their current situation of the research.(1)Long-time exercise to promote the mobilization of the fatty acids and branched-chain amino acids for energy,thus enhancing the plasma free tryptophan concentrations.(2)5-HT could not pass the barrier of blood-brain,b... |
