【摘要】：目的:在不干扰女运动员正常训练的情况下,探讨单纯补糖对运动性月经周期紊乱(EAMD)运动员生殖激素及能量代谢的影响。方法:将受试者随机分为补糖组与对照组,补糖组进行连续3个月经周期的补糖干预。实验前后均测量全部受试者的身体成分、能量状况及黄体生成素(LH)、雌二醇(E_2)和孕酮(P)水平。结果:实验后补糖组能量平衡由负转正,对照组无明显变化;实验后补糖组卵泡期E_2、黄体期P水平上升,与对照组有显著性差异,且黄体期P水平与受试者能量状况呈正相关;实验后补糖组卵泡期和黄体期LH、黄体期E_2、卵泡期P与对照组无显著性差异;补糖组、对照组在实验前后的相关生殖激素经组内比较均无显著性变化。结论:单纯补糖干预对EAMD运动员能量负平衡状况和相关生殖激素均有一定改善。
[Abstract]:Objective: to investigate the effects of glucose supplementation on reproductive hormones and energy metabolism of (EAMD) athletes without interfering with normal training. Methods: the subjects were randomly divided into two groups: the glucose supplement group and the control group. The body composition, energy status, (LH), estradiol (E _ 2) and progesterone (P) were measured before and after the experiment. Results: after the experiment, the energy balance of the glucose supplementation group changed from negative to positive, while that of the control group did not change significantly. The level of P in follicular phase and luteal phase in glucose supplementation group was significantly higher than that in control group, and there was a positive correlation between P level in luteal phase and energy status. There was no significant difference in E _ (2), P between the follicular phase and the control group in the follicular and luteal phase, but there was no significant change in the relative reproductive hormones in the glucose supplement group and the control group before and after the experiment. Conclusion: the energy negative balance and related reproductive hormones of EAMD athletes were improved by glucose supplementation alone.
