This study investigated metabolic and nutritional factors in association with athletic menstrual dysfunction (AMD). Three groups of women were studied: amenorrheic runners (amenorrheic), eumenorrheic runners (eumenorrheic), and eumenorrheic sedentary controls (sedentary). Amenorrheic and eumenorrheic were similar in age, weight, percent body fat by hydrodensitometry, training pace and mileage, best 10 km race time, years running, and maximal oxygen consumption. When adjusted for body weight or for fat-free mass by analysis of covariance, RMR was significantly lower in amenorrheic than in eumenorrheic and sedentary. The daily caloric intakes of the groups did not differ significantly, but the amenorrheic scored significantly higher than the eumenorrheic and sedentary on a scale of aberrant eating patterns. Amenorrheic high mileage runners seem to have a less adequate diet than eumenorrheic runners but appear to maintain energy balance and stable weight through a reduction in RMR.
本研究调查了与运动性月经功能障碍（AMD）相关的代谢和营养因素。研究了三组女性：闭经跑步者（闭经组）、月经正常跑步者（月经正常组）和月经正常久坐对照组（久坐组）。闭经组和月经正常组在年龄、体重、通过水下密度测量法测得的体脂百分比、训练配速和里程、10公里最佳比赛时间、跑步年限以及最大耗氧量方面相似。通过协方差分析对体重或去脂体重进行校正后，闭经组的静息代谢率（RMR）显著低于月经正常组和久坐组。三组的每日热量摄入量无显著差异，但在异常饮食模式量表上，闭经组的得分显著高于月经正常组和久坐组。闭经且高里程的跑步者似乎比月经正常的跑步者饮食更不均衡，但似乎通过降低RMR来维持能量平衡和稳定体重。
