中文摘要:

目的：以主客观两种方法调查女运动员运动性月经周期紊乱与能量负平衡的关系。方法：通过问卷对招募的14名受试者进行基本情况调查，同时连续测定一个月经周期晨尿的黄体生成素（LH）值和连续监控5 d的能量摄入与消耗情况。结果：通过主观问卷调查得出的运动性月经周期紊乱发生率（78.6%）与客观尿检LH值的方法得出的运动性月经周期紊乱发生率（92.9%）存在差异。总体能量呈负平衡状态，运动员平均摄入的能量低于平均消耗的能量474.82 kcal，其中，训练日平均摄入的能量低于平均消耗的能量588.86 kcal，休息日平均摄入的能量低于平均消耗的能量18.66 kcal。运动性月经周期紊乱与训练日的能量负平衡相关性较高（r=0.67）。结论：运动员中运动性月经周期紊乱的发生率较高，且存在主客观调查结果不一致的现象。女运动员普遍存在能量负平衡，并且训练日的能量负平衡与运动性月经周期紊乱相关性较高。

英文摘要:

Objective: To investigate the relationship between the Exercise-associated Menstrual Disturbance and the negative energy balance of female athletes by subjective and objective methods. Method: Through questionnaire, the basic information of the 14 subjects was collected. The LH value of morning urine was measured for a menstrual cycle and the energy intake and consumption were monitored for 5 successive days. Result: There is a difference between the incidence of Exercise-associated Menstrual Disturbance obtained by subjective questionnaire (78.6%) and that obtained by objective measurement of the LH value of morning urine (92.9%) . The total energy balance was negative. The average energy intake was lower than the average energy consumption by 474.82Kcal, in which, the average energy intake during the training days was lower than the average energy consumption by 588.86Kcal, and the average energy intake in the days without training was lower than the average energy consumption by 18.66Kcal. There is a close correlation between Exercise-Associated Menstrual Disturbance and the negative energy balance of the training days (r=0.67). Conclusion: High incidence of Exercise-Associated Menstrual Disturbance can be found in female athletes, and the subjective survey outcome is not in accord with the objective one. Negative energy balance generally exists in female athletes. And there is a high correlation between negative energy balance in training days and Exercise-associated Menstrual Disturbance.
