近十年来,从事长时间剧烈运动的女运动员日益增多。最近的资料表明,体育活动与月经初潮推迟、月经失调等症的发病率高有着因果关系。美国运动医学学会报告几乎有1/3的12～15岁的女子长跑运动员患月经失调(包括闭经或月经过少症)。运动与月经初潮调查者注意到,在月经初潮前即开始大运动量训练的少女,其初潮推迟继而月经失调的发病率明显高于那些初潮之后才进行训练的女子。这是因为她们青春期前能量消耗很大,而且还要保持体重轻。由于这两种因素的结果,青春期与初潮看来明显推迟。致病因素女子赛跑运动员出现继发性闭经的诱因很多,包括原先有月经失调、未产、应激反

Recent data indicate that there is a causal relationship between physical activity and the postponement of menarche and the high incidence of menstrual disorders.
