Abstract

The article presents data on the study of the timing of the first menarche in 143 athletes of puberty age - representatives of various sports (artistic gymnastics - 15 athletes, rhythmic gymnastics - 14, volleyball - 19, basketball - 17, cycling - 13, rowing and canoe - 12, freestyle wrestling - 15, taekwondo - 14, boxing - 13, athletics (middle distance running) - 11 people) in comparison with the general population age and sex group of 145 people. The relationship between the timing of the formation of the ovarian-menstrual cycle in female athletes and the time of starting sports was established. The dynamics of the formation of the ovarian-menstrual cycle has been determined. It was revealed that in each of the groups presented, the female athletes had an extended period for the debut of menarche and the onset of the establishment of the ovarian-menstrual cycle. The most influencing on violations of the debut of menarche and the formation of ovarian-menstrual cycle among athletes are such sports as artistic and rhythmic gymnastics, rowing and canoeing. The time of the beginning of sports activities and the time of the onset of menarche in the aggregate are an etiological factor that causes disturbances in the dynamics of the formation of the ovarian-menstrual cycle and a malfunction in the reproductive system of athletes in general and is the result of the body's adaptation to the physical and psychological stresses corresponding to these sports.
