With the increasing involvement of women in exercise programs, the physician is faced with more and more questions regarding the effect of exercise upon the reproductive system. Currently, it appears that premenarchal training may have the effect of delaying the onset of menses in some girls. There is no evidence that it delays the other stage of puberty or that it causes any harmful development by this delay. In the postmenarchal woman, strenuous exercise can definitely alter her bleeding pattern. The usual result is oligomenorrhea progressing toward amenorrhea as the exercise increases. This is not a universal phenomenon, however, and other factors such as percentage of body fat, stress, diet, and energy drain also play a role. The menses will usually resume its preexercise pattern after a period of rest.
随着女性越来越多地参与运动项目，医生面临着越来越多关于运动对生殖系统影响的问题。目前，初潮前训练似乎可能会使一些女孩月经初潮推迟。没有证据表明它会延迟青春期的其他阶段，或者这种延迟会导致任何有害的发育。对于初潮后的女性，剧烈运动肯定会改变其出血模式。通常的结果是随着运动量增加，月经过少逐渐发展为闭经。然而，这并非普遍现象，身体脂肪百分比、压力、饮食和能量消耗等其他因素也起作用。经过一段时间的休息后，月经通常会恢复到运动前的模式。
