| 摘 要： | 本研究运用时间生物学的研究方法,就力竭性运动对大鼠脑干、间脑和端脑3个脑层次中兴奋性氨基酸类神经递质谷氨酸(Glu)的量变及近似昼夜节律的影响进行了研究。结果发现(1)3个脑层次中Glu的含量表现出具有统计学意义的近似昼夜节律(P<0.01)。(2)择时运动对3个脑层次中Glu的含量及近似昼夜节律性产生明显的影响,其量变表现出“运动性双向量变”现象;其节律性改变表现为峰相位群体超前,中值和振幅改变。(3)为探讨“运动性双向量变”现象的生理学机制,我们提出“神经递质贮备”假说,认为“运动性双向量变”与运动前“神经递质贮备”状态有关。

| Abstract: | By methods of chronobiology, the effects of chrono-exercise on the circadian and amounts of glutamate neuro- transmitters in Rat's three brain levels (stem brain, diencephalon and telencephalon) were studied. The results showed that both neurotransmitters demonstrated a significant circadian, and chrono-exercise could make both amounts and circadian of the neurotransmitters .change. The changes of circadian concentrated on phase lead the changes of Mesor and amplitude. The changes of amounts displayed a "exercise-induced bi-direction changes" phenomenon. The hypothesis of "neurotransmitter reserve" was put forward to probe the physiological mechanism of this phenomenon. There is a close correlation between this phenomenon and neurotransmitter reserve. |
