Menstrual dysfunctions, their connection with body composition and the level of physical activity burden in the sample of elite bosnian sportswomen

摘要

Low energy availability (with or without eating disorder), amenorrhea and osteoporosis, alone or coupled as a Female Athlete Triad pose a significant health risk for sportswomen and physically active women. The objectives of the research were as follows: 1) determine the prevalence of menstrual disturbances in the sample of sportswomen (N=84) and the control group (N=27), 2) examine the influence of body composition (BMI, % BF) and the intensity of training on the menstrual cycle. The primary amenorrhea, secondary amenorrhea and oligomenorrhea prevalence was significantly higher in the sportswomen group (12/84), (9/84), (11/84) in comparison to the control group (0/27). The value of the %BF was statistically significantly lower (p<0,05) in oligomenorrheic sportswomen (11,64%) in comparison to the eu-amernorrheic ones (16,60%). The highest intensity of training was in the group of athletics sportswomen (13,98h/week) which was found to have the most menstrual dysfunctions.
