The purpose of the work was to study the peculiarities of the change in the indicators value of training load in power fitness under conditions of using different modes of muscular activity in terms of volume and intensity. Materials and methods. The study involved 50 untrained males aged 18-20 years. 2 research groups of 25 people each were formed: control and main. The participants of the control group used the regimen of low-intensity and large-volume loads developed by us. The representatives of the main group used a regimen of high-intensity loads with the use of time indicators of muscular activity of different parameters. Control over changes in the value of training load indicators was carried out using the following methods: determining the development of maximum muscle strength of the studied contingent in control exercises; quantitative assessment of the level of physical activity in power sports. Results and discussion. The obtained results on the dynamics of the average group indicators of the maximum mass of the projectile when performing training exercises among the surveyed contingent, allow us to conclude that under long-term use of high-intensity loads regimen, the maximum power capabilities of the body develop almost 3 times faster compared to the data fixed during the same period of time in the conditions of application of a low-intensity regimen. In turn, despite a significant (about 51.0%) increase in the parameters of the load in the working set among the representatives of the main group during 3 months of the study, due to an increase in body’s strength capabilities by 36.0%, the results found at the end of the study were 6.8% and they were lower compared to the initial data set among the representatives of the control group. It was investigated that the most pronounced increase in the parameters of the load in the working set by 59.3% (p <0.05) compared to the initial data, was recorded among the representatives of the main group when performing the basic exercise "bench press" in the conditions of using the regimen of high-intensity and low-volume load. It is established that the use of the regimen of power loads developed by us in the process of training activity contributes to the accelerated growth in the parameters of the projectile working mass indicator (by more than 30%) among men of the main group in comparison with opponents. At the same time, it was among the representatives of the main group who used the regime of high-intensity and low-volume loads during training, the indicator of the volume of work in a separate set was almost 70% lower compared to the data recorded among the control group. Conclusion. Against the background of increasing intensity parameters and simultaneously reducing the volume of training work, the results obtained may allow to find one of the effective ways to solve the most relevant problem of modern sports activity, namely, to suspend the process of a constant increase of the values of training loads to provide the body of athletes with the necessary, for further pronounced adaptive changes, stress stimulus and it will help reduce the level of injuries in power sports
