Indicators of dehydroepiandrosterone in athletes engaged in sports acrobatics, in a state of muscle rest and after standard physical exertion

Relevance. Hormones secreted by the endocrine glands demonstrate the most important interest in organizing adaptation to specific muscle activity. A significant role in the functional «formation» of the endocrine system of the body is brought by hormones – androgens. There are fragmentary studies on the effect of sports on the parameters of dehydroepiandrosterone. At the same time, the analysis of the effects of the hormone in question in athletes specializing in sports acrobatics allows us to realize the mechanisms of the formation of stress reactions at different periods of the training cycle. The aim of the present studies was to determine the content of DHEA in highly qualified acrobats at rest and after standard physical activity. Organization and methods of research. The studies involved 27 athletes specializing in sports acrobatics (sports qualification master of sports and candidates for master of sports) aged 17-21 years and 30 practically healthy peers who are not involved in sports. Collection (in SaliCapSet , a system for collecting saliva samples) and analysis of saliva was carried out in a state of relative muscle rest and after standard physical activity PWC170. DHEA indicators were determined by enzyme immunoassay using the SANRAIS analyzer (Tecan, Austria). The results obtained were processed using applied statistical programs, with the determination of the arithmetic mean and standard error of the mean. Differences between groups (according to Student) were recognized as reliable at p<0.05. The results of the studies conducted in the saliva of acrobats at rest and their peers who do not engage in sports, DHEA was 1.17±0.08 kg / ml in the group of athletes, in the second group 1.62±0.13 kg / ml (t = 2.95; p<0.05). Analysis of DHEA in the subjects after standard physical exertion showed the level of the hormone increased by 1.58±0.14 kg / ml (t = 2.54; p<0.01), while in the group of nonathletes it significantly decreased by 1.26±0.06 kg / ml (t = 2.51; p<0.01). Conclusion. Consequently, the scientific information presented demonstrates the fact that the quantitative parameters of DHEA can be used as non-invasive means of monitoring the functional state of athletes engaged in sports acrobatics. At the same time, the study of DHEA in saliva is simple, «comfortable» and atraumatic collection, the absence of infection during the collection of biomaterial, and the repeated receipt of samples in the optimal way with dynamic observation of the collection Athlete. High intensity of sports is accompanied by a greater amplitude of fluctuations in DHEA. The determination of DHEA in saliva can be used as a preferred test that characterizes the level of tension of the adaptive capabilities of the body of athletes engaged in sports acrobatics.
