Key words: transcranial micropolarization, polyathlon.

Introduction.
Objective: to assess the possibility of using micropolarization (MP) for the development of power abilities.
Methodology and organization of research. The pilot study involved athletes - polyathletes 18-22 years old, 16 people: 8 in each in the control and experimental groups. The groups were offered the same methodology for the development of strength abilities by the method of unsatisfying efforts to the utmost fatigue in one approach, with the simultaneous use of MP (Brainstorm neurostimulator). MP - transcranial micropolarization - a method that allows you to selectively change the functional state of neurons, through the action of a constant electric current of low strength (up to 0.7 mA) and density (0.01 - 0.1 mA per square cm.) [1, 2]. Training session: 3 approaches - pulling up on a high crossbar with a pace of 12 repetitions per minute, rest interval 5 minutes. During the MP, two electrodes (anodes) and one electrode (cathode) were applied to the projection of the motor zone of the cerebral cortex on the right shoulder. The control group used the MP device - a placebo. The duration of the experiment is 2 weeks - 6 training sessions.
Results. The increase in control test indicators in the experimental group was 19% (19.0 - 23.3), while in the control group it was 12% (19.7 - 21.7). In the experimental group, the growth of the result reaches the threshold of statistical significance, whereasin the control group - no. To clarify the effect of MP, it is necessary to expand the sample and conduct in-depth studies of physical performance [3].
Conclusions. The MP technique in the experiment helped to improve the result of the pull-up exercise on the high bar. Probably, it can contribute to increasing the effectiveness of the development of power abilities.
