摘要(Abstract):

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(E2)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E2、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E2、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。
This study aims to discuss how carbohydrate supplementation affects the energy expenditure and reproductive hormone in female athletes with Exercise-Associated Menstrual Disorders(EAMD)without disturbing their regular training. Methods:Participants were randomly assigned into experimental carbohydrate group and control group. The experimental group was given carbohydrate intervention for 3 consecutive months. Body composition, energy expenditure and LH, E2, P were measured in both pre- and post-study for all participants.Results:The experimental group achieved positive energy balance after 3-month intervention, removing its negative energy balance in pre-intervention. No significant difference, however, was found within the control group. The release of E2 and P elevated in follicular phase and luteal phase respectively after the carbohydrate intervention, different from control group significantly; and that of P in luteal phase is positively correlated with energy expenditure. Moreover, no significant difference was observed in the relase of LH and P in follicular phase and that of LH and E2 in luteal phase between the two groups after the study, and the reproductive hormone in both groups stayed relatively stable before and after the study. Conclusion:Carbohydrate supplementation ameliorates the situation of negative energy balance and the release of related reproductive hormone in female athletes with EAMD, which has implications for the prevention and treatment of EAMD in female athletes.
