title: GLUCOCORTICOID ACTIVITY OF THE ADRENAL CORTEX IN THE BODY OF HIGHLY QUALIFIED ATHLETES WITH DIFFERENT LEVELS OF FUNCTIONING OF THE REPRODUCTIVE SYSTEM
abstract: Athletes with an average menstrual cycle duration of 28-30 days, 37-45 and 16-26 years old were examined. Enzyme immunoassay of gonadotropin and sex hormones, immunochromatographic in vitro ovulation test, and statistical data analysis were performed. In athletes with an anovulatory menstrual cycle, the range of glucocorticoid response to threshold physical activity narrows, which limits their compensatory and adaptive capabilities. Taking the oral contraceptive drug Mercilon causes an increase
