The association of menstrual dysfunction and weekly running mileage was investigated in a group of habitual women runners, categorized into high mileage runners (30 or more miles/week) and low mileage runners. Both mileage groups reported menstrual changes and weight loss since starting to run. Menstrual irregularities (35 or more days between cycles) were reported more often among the high mileage women than among the low mileage women (p = 0.001). However, after controlling for cycle irregularity before starting a running program, the effect of mileage was no longer statistically significant. While these results suggest that pre-running menstrual irregularity is more important than higher doses of weekly mileage, further investigations are needed to assess the role of potentially confounding factors such as stress, diet, and other lifestyle changes that may occur with increased exercise.
在一组习惯跑步的女性中，对月经功能障碍与每周跑步里程之间的关联进行了调查，这些女性被分为高里程跑步者（每周30英里或更多）和低里程跑步者。两个里程组都报告说自开始跑步以来月经有变化且体重减轻。高里程女性中月经不规律（月经周期间隔35天或更长）的报告比低里程女性更频繁（p = 0.001）。然而，在控制开始跑步计划前的月经周期不规律情况后，里程的影响在统计学上不再显著。虽然这些结果表明跑步前的月经不规律比每周更高的里程数更重要，但需要进一步调查以评估潜在混杂因素的作用，如压力、饮食以及随着运动量增加可能发生的其他生活方式变化。
