摘要
运动性中枢疲劳首先是由运动所引起的,使其中枢神经系统不能够产生和维持足够的冲动到运动所需的肌肉现象.然而引起运动性中枢疲劳的因素很多,例如能量的供应不充分,氨中毒、中枢氧化还原状态不平衡,以及中枢神经递质发生了一些改变等等.长时间运动所引起的中枢神经递质的变化被看成为引起运动性疲劳的最主要的机制,也就是说,当中枢的兴奋性和抑制性不能够达到一个相对平衡的状态时,就会引起运动性疲劳的产生.本文对运动性疲劳的中枢机制进行综合的分析,重点阐述中枢单胺类神经递质与中枢氨基酸神经递质发生紊乱时对运动能力的影响及与运动性疲劳产生之间的关系.
The sports central fatigue is caused by movement first.It is a phenomenon that the central nervous system can＇t able to generate and maintain sufficient impulse to the muscle of the movement required.However,there are many factors can caused sports central fatigue,such as the insufficient of energy supply,ammonia poisoning,the imbalance of central redox state as well as some changes of the central neurotransmitter.The changes caused by prolonged exercise in neurotransmitter of the central nervous system are seen as the most important mechanisms cause exercise-induced fatigue.That is,the sports fatigue,can be generate when the excitatory and inhibitory of the central not be able to achieve a relatively balanced state.This paper reports a comprehensive analysis of the central mechanisms of exercise-induced fatigue,it focuses on the relationship between the generation of the sports fatigue as well as the influence of the sports ability,and the disorder of central monoamine neurotransmitters and central amino acid neurotransmitters.
