The article presents the results of researching the problem of the informative value of the endocrine system indexes in conditions of various intensity power loads. Necessity of studying was caused by measuring the impact degree of high power load of different fitness training on the level of testosterone concentration in the blood of people with different physical fitness levels. Materials and Methods. 20 athletes aged 19-20 years and systematically engaged in power fitness were involved in the studies. There were also 20 young men of similar age who do not have contraindications for training with weights. Laboratory tests of testosterone concentration in blood serum were performed four times throughout the study period before the load and after the training session. Results and Discussion. In the course of research it was found out that despite the low initial level of testosterone in the blood of trained young men at the beginning of the research, a hormonal response to the proposed power load, fixed for three months of exercise in the prescribed conditions of the motor activity, demonstrated an increase in the content of testosterone in their blood in comparison with the state of rest. The results of the operative control of the hormonal response to the power load, fixed after the first month of research, demonstrated an increase in the content of testosterone in the blood of trained athletes (+ 8.2%), as well as untrained young men (+ 9.9%) in comparison with rest. At the same time, a significant increase in the relative weight in young men of both groups (from +15.50% (p <0.05)) in trained athletes to 26.9% (p <0.05) in untrained). Conclusion. The obtained results demonstrated an increase in serum testosterone concentration in both groups. There were significant positive changes in the values of body power capabilities and its morphometric indicators throughout the experiment, regardless examinee’s level of fitness. Moreover, it was revealed that despite the high level of the trained young men’s body adaptation to power work of this nature, the change in several parameters of the training load and the motor activity regime caused the same hormonal response in untrained young men.
