AI Article Synopsis
- A study involving 10 male and 15 female judo players examined changes in urine steroid levels before and after a treadmill exercise test using gas chromatography-mass spectrometry.
- Males showed significantly higher concentrations of testosterone and epitestosterone post-exercise, while their etiocholanolone-dehydroepiandrosterone (DHEA) ratio was lower compared to females.
- Exercise led to a significant decrease in etiocholanolone levels in both genders, and in females, the 11-OH etiocholanolone concentration also dropped, with a positive correlation identified between changes in etiocholanolone and epitestosterone.
Article Abstract
A heterogeneous group of 10 male and 15 female judo players are utilized in this study. The subjects complete a standardized maximal treadmill exercise test. Urine samples are collected at the pre- and postexercise stages. The urine steroids are measured using a gas chromatography-mass spectrometry instrument. In rest and after exercise, significantly higher testosterone and epitestosterone concentrations in males (p < 0.01) are found. The etiocholanolone-dehydroepiandrosterone (DHEA) ratio is significantly lower in males than females (p < 0.05). In both males and females, etiocholanolone concentration significantly decreases with the effect of exercise (p < 0.05). 11-OH etiocholanolone concentration also significantly decreases, but only in females (p < 0.05). Positive correlation is found between the changes of the etiocholanolone and epitestosterone concentration caused by exercise.
