过度训练对大鼠垂体—性腺轴的影响

The Effect of Overload-training on the Pituitary-gonadal Axis of Rats

为了探讨过度训练对机体垂体—性腺轴的影响，通过ＳＤ大鼠进行力竭力性游泳训练建立过度训练模型，并测定血清睾酮（Ｔ）、黄体生成素（ＬＨ）和皮质醇（Ｃ）的含量。结果表明：过度训练可抑制的诊断和预防具有一定的指导意义。

In order to explore the effect of overload-training on the pituitary-gonadal axis of rats,the overload-training model was established through exhaustive swimming training on SD rats. The serum testosterone(T), iuteinizing hormone(LH) and cortisol(C) concentration were measured after training. The results suggested that the overload-training can restraint the function of the pituitary-gonadal axis. The dynamic observation of the serum T and T/C may reflact the orgamism's functional state, and has some guiding significance to diagnose and frevent the overload-training.
