FIELD: sports.
SUBSTANCE: invention relates to the field of sports, in particular to the training of volleyball players. When performing a block on the grid, the player steps on the contact surface intended to close the electrical contacts, and pushes it off to jump, thereby closing the electrical circuit, the corresponding signal is transmitted through the electric wires through the control unit, which is intended to form a signal and transmit it through the electric wires on the scoreboard with indicating lights (IL), which light up on the scoreboard in random order and are intended to simulate the direction of attack of a directing strike, while the player, in a jump, puts the block, covering with his hands the direction indicated by the IL.
EFFECT: technical result of the proposed invention is to increase the speed of reaction of volleyball players when performing “moving” blocks in a jump at the time of modeling an opponent's attack, developing the correct technical and tactical actions.
