The article presents the results of studying the effects of various training programs in fitness in the dynamics of the maximal muscle strength growth of healthy, untrained men aged 19±1.1 years during 3 months of training. Material and methods. Fifty men participated in the experiment, and we divided them into 2 study groups. The proposed training programs differed from each other mainly by the duration of the recovery intervals between sets and the speed of performing power exercises. This affected the duration of muscular activity in a separate set, the values of the projectile working mass and the amount of load in the working set. To determine the features of these indicators’ change in the proposed conditions of training activity, we used an integral method of estimating the magnitude of the load. Results and discussion. In the course of the research, we found out that using a rather brief (about 40 s) and simultaneously unusual for the fitness rest intervals between the sets by the representatives of the 2nd group, contributed to the changes in the magnitude of the load indicators. It also significantly influenced the adaptive changes in athlete’s body in comparison with the 1st group representatives’ results. Thus, the maximal muscular strength indicators increased by almost 20% in the 2nd group representatives during 3 months of training compared to the results fixed in men of group 1. At the same time, the value of the load volume indicator in the working set reduced almost by 2.2 times in the 2nd group representatives during all stages of the study in comparison with the results in the other group. Conclusions. The decrease in the rest time between sets affected the increase of the load intensity and significantly reduced the amount of training work in the training process. This happened because of doubling the duration of the concentric and eccentric phases of movement. Corresponding correction of the training load values positively influenced the processes of body adaptation to the stress stimulus in conditions of power fitness training.
