A group of 381 girls, 12 up to 19-years-old, engaging in competitive sports (athletics, basketball, dancing, gymnastics, swimming, ski-ing, tennis, volley-ball) was examined. Age at menarche and menstrual characteristics were correlated with the body weight, the competitive practice start age, the kind of the sport and the amount of training hours/week. Collected data were compared with the ones from a pool of 387 girls of equivalent mean age, not playing any sport. Delay of menarche and larger frequency of menstrual disorders, found among athletes, turned out to be directly proportional to the amount of time devoted to training and to the kind of performed sports. Irregular cycles are more frequent in athletes having a normal or lower body weight and do not normalise proceeding in sporting activities.
对一组年龄在12至19岁之间、从事竞技运动（田径、篮球、舞蹈、体操、游泳、滑雪、网球、排球）的381名女孩进行了检查。月经初潮年龄和月经特征与体重、开始竞技训练的年龄、运动种类以及每周训练时长相关。将收集到的数据与来自平均年龄相当、不参加任何运动的387名女孩的数据进行了比较。结果发现，运动员中月经初潮延迟和月经紊乱频率较高的情况与训练时间和所从事的运动种类直接相关。月经周期不规律在体重正常或较低的运动员中更为常见，且在继续进行体育活动时不会恢复正常。
