Fourteen normal women (self-selected from 180 women enrolled) in a marathon training clinic kept basal body temperature (BBT), mileage, and weight records for 48 cycles before the marathon. Entry criteria were: Age 20-45, gynecologic age greater than 5 years, no hormone use, or weight change in 3 months. The women were 35.2 +/- 5.6 years in age, 22.6 +/- 5.1 years gynecologic age, runners of 4.1 +/- 2.5 years with premenstrual symptoms, previous pregnancy 4/14, no infertility and 2/14 remote amenorrhea. BBT records were obtained and analyzed by Vollman's criteria (1977). There was no weight loss. 32/48 cycles were biphasic but only 16 were normal in the length of the premenstrual phase (PreM = luteal, nl 10 - 16 d) with a mean of 11.1 +/- 1.2 days. The other 16 biphasic cycles had short PreM phase of 6.4 +/- 1.8 days. Monophasic (M = anovulatory) cycles occurred in 16/48 records. Cycles which were abnormal (Short PreM and M) differed only in that usual run length was longer (9.6 - 9.9 miles) than in normal cycles (7.9 +/- 2.4 miles). Marathon training may be associated with normal length but M and short PreM type cycles.
在一家马拉松训练诊所中，从180名登记的女性中自行挑选出14名正常女性，她们在马拉松比赛前记录了48个周期的基础体温（BBT）、里程数和体重。入选标准为：年龄20 - 45岁，妇科年龄大于5岁，未使用激素，且3个月内体重无变化。这些女性的年龄为35.2±5.6岁，妇科年龄为22.6±5.1岁，跑步年限为4.1±2.5年，有经前症状，既往妊娠史为4/14，无不孕史，2/14有远期闭经史。BBT记录按照Vollman标准（1977年）获取并分析。体重没有减轻。48个周期中有32个呈双相型，但只有16个周期的经前期（PreM = 黄体期，正常为10 - 16天）长度正常，平均为11.1±1.2天。另外16个双相型周期的经前期较短，为6.4±1.8天。48份记录中有16份为单相型（M = 无排卵型）周期。异常周期（短经前期和单相型）与正常周期的唯一区别在于，异常周期的通常跑步里程（9.6 - 9.9英里）比正常周期（7.9±2.4英里）更长。马拉松训练可能与正常长度的周期相关，但也与无排卵型和短经前期型周期有关。
