摘要
观察了长期游泳训练对小鼠脑组织递质性氨基酸和５－羟色胶水平的影响。结果表明：经过４５天游泳训练后完成力竭性运动，训练组小鼠与对照组相比，脑组织抑制性氨基酸递质ＧＡＢＡ、Ｇｌｙ、Ｔａｕ均上升，其中Ｇｌｙ升高明显（Ｐ＜０．０５）；兴奋性氨基酸递质Ｇｌｕ、Ａｓｐ仅出现下降趋势，但无统计学意义（Ｐ＞０．０５）。Ｇｌｕ／ＧＡＢＡ比值的下降也无显著意义，而脑组织５－ＨＴ浓度升高显著（Ｐ＜０．０２）。提示：训练对脑组织递质性氨基酸有重要影响，可一定程度提高脑组织神经活动的稳定性和对运动的适应性，５－ＨＴ可能是运动性中枢疲劳较为敏感的神经介质。
The purpose of this study was to investigate the effects of swimming training on neurotransmitter amino acids ad serotonin5-HT)ub nuce braub The results showed that After exhaustive swimming following 45 days swimming traninig there was and increas ing trend in the inhibitory amino acids gamma-aminobutyric acid (GABA) glycin (Gly) smf taurine(Tau)in the training group.the excitatory amino acids glutamate (Glu)and Aspartates(Aso)decreased (Asp) The Glu/GABA ratio was decreased too all theseoccurred with no remarkable difference while-5HT concentation was increase significanlty (p<0.02)The above data suggestthat to a certain extent training has important effects on meurotransmitter amino acids in the brain enhancing the stability of vous activities of the brain tissues, and their adaptability to. exercise. And that 5-TH might be a kind of neurotransmitter with a higher sensibility to central fatigue during exercise.
