Objective of the study was to determine the effects of skeletal muscle relaxation on athletes' physical fitness levels.
Methods and structure of the study. The research method applied for the study purposes was computer polymyography developed by Yu.V. Vysochin. The experiment involved the football and hockey players of the children and youth sports schools of Naberezhnye Chelny, Yekaterinburg, and Chelyabinsk. The battery of tests included: 15 m run from standing start (15 cm), 15 m run with flying start (15 cm), 30 m run from standing start (30 cm), standing triple jump (3 cm), and 5x70 m shuttle run.
All the participants of the experiment were divided into two groups depending on the muscle relaxation rate (MRR). Group 1 included the athletes with the high MRR and Group 2 - with the low MRR.
Results and conclusions. The athletes with the high MRR (Group 1), who could tolerate heavy physical loads, were able to endure the tense preparatory period and entered the competitive season in excellent shape. For the athletes with the low MRR (Group 2), the same physical load turned out to be excessive, which was shown in the progressive deterioration of the professionally important athletic qualities.
Consequently, the application of an integrated system of relaxation training makes it possible to achieve the best end results simultaneously in terms of all efficiency and adaptation criteria: high levels of energy cost efficiency, speed of the recovery processes, physical and psycho-emotional stress tolerance, physical development and technical skills, as well as the preservation of the health and long sports career of athletes.

Keywords: adaptation, relaxation characteristics, athletes, functional state, sports result.
