All of the 20 subjects aged 15-19 years were national elite rhythme gymnastic athletes. They had been trained for 4-10 years, and 13 athletes had sports grade of master sportsman (one of them has not had menes aged 16 years). Their menstruous states were investigated and bone mineral states were determined. The results, indicated that elite rhythmic gymnastic athletes were in a serious condition of menstrual dysfunction. Sixteen athletes were in abnormal minstruation among nineteen athletes, the average was 84. 2%. The mean BMD of these athletes decreased, compared will ordinary people. That was to say the results did not reveal the advantage of sports on bone growth and develpment in atbletes of menstrual disorder which might relate to menstrual dysfuncton. Further analysis made it clear that BMC and BMD of athletes in indefinited menstruation, amenorrhea and menorrhalgia, were significantly lower compared will athletes in eumenorrhea. The results might be taken as a warning to elite athletes of their bad health condition. It is necessary to make further study on exertional menstruous disorder, because part of the female athletes are in abnormal menstruation.
