Nowadays, there is pressure in the society to achieve more and more spectacular sports results. Active people often reach for exogenous hormones to accelerate the process of adaptation of the organism to the effort and to achieve satisfactory results. One of them is sold as a diet supplement dehydroepiandrosterone (DHEA). The aim of the study was to determine the effect of DHEA supplementation by athletes on the concentration of dehydroepiandrosterone and cortisol in their body. For study 13 athletes aged 21-33, that declared DHEA supplementation were selected. Levels of hormones were tested before (2 weeks) and during (4 weeks) supplementation with Demeditec ELISA immunoassays. Samples were collected as recommended by the producer, weekly on Saturday at 10 am. Statistica 13 was used for statistical evaluation. The mean DHEA levels in the first two weeks of study prior to initiation of supplementation were 454.649±277.143 (175.603�??973.441) and 778.920±584.416 (221.102�??1781.2) respectively. After a week of application, the concentration of hormone increased significantly in all subjects, reaching an average of 3909.555±5568.371 (509.249 �?? 20447.25). In the following weeks, the amount of hormone fell. The greatest concentrations were achieved after one or two weeks of supplementation. After 4 weeks of use, the DHEA level returned to the pre-supplementation level, or for those who did not reach the normal range, reached a value suitable for age and gender. There were no changes in cortisol concentrations observed that could be associated with DHEA supplementation. Modifications in steroid hormone concentrations can lead to increase of athletes�?? strength, performance and fitness, by affecting the muscle growth, bone density, nervous system regeneration, and others. Physical exercise, especially sports training, causes adaptive changes throughout the organism, including the motor, nervous and hormonal systems.
