摘　　要：为运动性中枢疲劳的研究提供理论依据,建立持续游泳的动物模型,探讨一次性耐力运动对大鼠间脑单胺类神经递质变化及代谢能力的影响。结果为①3h游泳后即刻,间脑5-HT增加23.15%,至少可通过神经-内分泌调节、体温调节、情绪变化等因素影响机体的运动能力;②一次性耐力运动期间,间脑5-HT合成过程占优势,分解过程变化不明显,而恢复期分解代谢过程占优势;③一次性耐力运动可显著降低间脑DA水平,5-HT与DA比率亦显著性升高(P<0.05),20h恢复期间脑DA浓度增高,5-HT与DA比值降低(-27.51%)。This study was designed to observe the changes of 5-HT,DA,5-HIAA and DOPAC in diencephalon of the rat immediataly after three hours swimming and during its twienty hours recovery,and inquire into the influence of acute endurance exercise on dynamic change of menoamine neurotransmitter and its metabolic ability in the diencephalon of rat.Results were:① immediacy after three hours swimming,the 5-HT of diencephalon of rat increased 23.15%,which could affect the exercise ability of the body through neuroendocrine regulate and the adjustment of temperature and the change of mood,etc.② During acute endurance exereise,the synthetic process of diencephalon 5-HT occupied superiority,whereas the process of catabolism had not clear change.But during recovery,the process of catabolism occupied superiority.③ Acute endurance exercise could reduce the leved of DA and 5-HT/DA ratio remarkably.
