The invention relates to sports, namely, devices for training volleyball athletes.

The aim of the invention is to increase the effectiveness of the training by improving the tactical actions of the player during the development of various options for an attack hit.

Figure 1 shows the device, a general view; Fig. 2 shows a holder attachment unit; in FIG. 3, a belt conveyor with holders.

The device comprises a base 1, made in the form of a platform, a support 2 fixed on it, carrying a cantilever beam 3 with a drum 4, the axis of which is parallel to the base 1. The beam 3 is fixed on the axis of the drum 5. The axis of the drum 5 is placed in a slot 6 made in the support 2 can be moved along it and secured with a nut 7. The drum 8 is installed in the support 2 and is connected by a flexible 9 with a drive 10. The axes of the drums 5 and 8 are parallel to the base 1. The endless belt 11 covers the drums 4.5 and 8. Ea the tape 11 is fixed supporting elements 12S to each trunk which is a U-shaped bracket, in which there are bends aligned openings for attachment by a screw and nut end 13 of the rod 14 of adjustable length, made in the form of a lanyard. At the other end of the rod 14 is fixed a spring holder 15 m by 16. The axis of the drum 5 is connected to a rod 17 of adjustable length, both parts of which are connected by a lanyard 18. The lower part of the rod 17 by means of

the hinge 19 is connected to the base 1. The base 1 is provided with rolling bearings 20.

The device is used as follows.

The device is installed on the platform in the place required for practicing the techniques so that the side of the tape 11 is parallel to the volleyball net and is 5-10 cm away from it. Then set the balls 16 in the holders 15, positioning them on the hitting (with the body turning) distance from the net (10–30 cm) and from each other (10–30 cm), determined by the tactical variant of the attacking blow and by the individual abilities of the attacking player. For this, removable rods 14 are installed in selected support elements 12 J, adjusting the length of rods 14 and turning them in the supporting elements, select the indicated distances and fixing the position of the rods 14 with nuts 13. The holders 15 are installed in parallel grid around them. planes x. Adjustment of the height of the position of the mute 16 above the grid occurs simultaneously with the specification of the trajectory of their movement. To do this, select the required angle of inclination of the tape 11 (its lower part) to the base 1; loosening the nut 7, turn the lanyard 18, move the axis of the drum 5 into the slot x 6 and fix it with the nut 7. Attack places can be marked, for example, with a cloth pointer

mi attached to the grid. If for practicing an offensive strike it is necessary that the missiles move along an upward trajectory, then their holders are set closer to support 2 before the attack, if for practicing an offensive strike it is necessary that the missiles move along a downward path, then This is established closer to the free end of beam 3, and the direction of movement of the belt 11 is reversed by reversing the drive motor 10. The attacking player and the players of the opponent block take places on the court randomly or as required m away from pointers at the team coach.

The options for practicing an offensive strike are manifold, but the less complex ones are worked out first, and

then more complex i

Less complex options include exercises that are performed without interacting with the players of the opponent. In order to practice this option, the attacking player takes the designated place by the coach before the attack, the coach switches on the drive engine 10, so that the ball 16 moves to the attack site, and names the number of the ball on which the offensive strike should be made, in words first or second, and when jumping out (or when performing a preliminary squat for jumping out), suddenly calls a different number. The place of the attack may not be indicated, then before the athlete jumps, the coach gives the preliminary command attack-first or attack-second, also unexpectedly for the athlete, changing the number of the ball on which the offensive strike should be made. The task is then complicated by the fact that the trainer changes the angle of inclination of the trajectory or the direction of movement of the bomber or the speed of their movement. After the attacking player learns to coordinate his actions in these game situations, it is suggested to work out more complex tactical options involving the players of the opponent’s block. When processing the actions of an athlete in this variant, the trainer uses the described methods of giving commands, the opponents put the block, react to them, and the attacking player must beat the block, one

cutting the opponent's actions, and if necessary, the opponent may unexpectedly decide to make an attacker on another ball, contrary to the coach’s command, and an attacker makes a turn with the body turning to the left or right past the opponent’s hands

In all variants of the attacking strike with the rotation of the trunk, its rotation is regulated by setting the ball to the desired position. To do this, first position one of the holders, turn the screw 13, remove it from the support element 12 and insert the rod 14 with the holder between the bends of the other support bracket

element 12 so that coaxial holes (not indicated) in the bends of the bracket are aligned with the hole in the rod 14 and, adjusting the angle of the holder to the grid, as well as the length of the rod 14, fix the holder in the support element with a screw 13. If there is a need changing the position of the masses to regulate only the range of movements of the athlete depending on the adjustment of the trainer's task during the practice of the attack hit, the holder did not move to the other supporting element 12, is limited only by adjusting the length of the st 14 and changing its angle to

grid as described. I

Repeated exercise - an attack hit with a rotation of the body in various ways - the athlete improves the motor actions necessary for the successful implementation of this exercise, which is achieved by coordinating the player's actions based on temporary anticipation (advance), allowing the athlete to choose the place of attack in a timely manner, to flexibly adapt their own movements to the characteristics of the moving player and the opponent's block.

Compared with the known device, it possesses wider functionality, allowing the attacking athlete, when working out his tactical options of an attacking strike with a torso (left or right), select and change the desired position of the ball, the direction and speed of its movement in simple 1

relative to the grid, thus providing an opportunity to improve their motor actions, ahead of the actions of the players of the opponent’s unit, which generally contributes to the effectiveness of the training of the attacking actions of volleyball athletes.
