Description

The invention relates to the field of sports, in particular to the training tools necessary for preparing for competitions, the formation of technical and tactical actions in the defense and development of athletes of volleyball players with special physical qualities.

Currently, the improvement of the technical and tactical actions of volleyball players in defense is provided using a comprehensive training method that involves the use of outdoor and sports games, relay races, jerks and accelerations, smooth running, and jumping exercises. The most effective for the development of speed of movements is versatile physical training with emphasis on speed-strength exercises. (see. Textbook. Volleyball "Physical Education, Education and Science" Moscow, 2000. It is approved as a textbook for institutes and academies of physical education. Pages 32, 33.

In addition, it is known a device for improving the motor reaction of volleyball players containing a contact surface from which the athlete pushes off with his legs, closing the electric circuit and the signal is transmitted via electric wires through the control unit, in which a signal is generated in random order, transmitted via electric wires to the light signaling devices located on the panel, informing the direction of an imitating attack of the opponent, when the athlete touches with his hands the fixation sensors located on the light signaling devices x, at the same time it is possible to determine the speed of his reaction when setting up the block, and due to the stretching in the jump of the rubber rope fixed with a belt on the body and with the rope fixed on the floor, an additional effort is created on the athlete's legs, increasing his speed-power indicators, data from the results of the training process are displayed on the monitor. (see. Description of the device “Device for improving the motor reaction of volleyball players.” RF Patent No. 2669854 Published October 16, 2018 Bull. No. 29. Author DL Kochanov Open edition. Prototype).

The known device for improving the motor response of volleyball players allows you to develop the speed of the motor reaction of the players, to develop the right technical and tactical actions when performing the block, to improve speed and power qualities, to ensure quality control of the training process, expressed in the determination, the speed of the athlete from the moment the jump starts to the moment of blocking striker hit.

However, the disadvantage of this device is that it does not fully solve the problem of monitoring the implementation of technical and tactical actions in defense and assessing the level of preparedness of each athlete in a team. This device allows you to record only the period of time the athlete begins to push off the floor when jumping to the correct position of his hands in the final phase of the flight. Thus, it is not possible to fully simulate the game situation with monitoring all the technical and tactical actions of the player, including: the player’s reaction to the start signal with subsequent movement to the place of repulsion from the floor during the jump and choosing the right direction to block the opponent’s attack hit.

The objective of the present invention is to monitor the technical and tactical actions of the player in defense, simulating various game situations, assess the level of preparedness of volleyball players when performing technical and tactical actions in defense aimed at improving single blocking, expressed in determining the response time of an athlete to a signal to start movement , determining the speed of his movement on the playing field, in choosing the right direction in the player’s hands in the final phase of the field that when blocking.

The technical solution of the proposed invention is the use of a trainer with light start signaling devices, light signaling devices with touch sensors, a signal processing unit, a monitor and a contact surface with motion sensors connected by a wire to a single system.

The technical result of the proposed invention is the ability to control the technical and tactical actions of the players in defense and assess their level of preparedness when performing a single block at the time of modeling various game situations. Identification of errors and making adjustments by the coaching staff when performing technical and tactical actions in defense, as well as intensification of speed-strength endurance of players.

At the same time, the essence of the device for monitoring the technical and tactical actions of volleyball players in defense is based on the fact that during the training process, the technical and tactical actions of the player, in particular: the athlete’s reaction time to the signal to start moving, the speed of movement on the playing court, the choice of the correct direction of setting the player’s hands in the final phase of the flight during blocking and hopping endurance are improved by supplying a signal from the signal processing unit to one of the start light signaling devices on the panel, in Aulnay order. Responding to a light signal, the athlete crosses the area of the playing field, in which the light beam propagates from the motion sensors, at this stage, the athlete's reaction time to the light signal is determined. Next, the athlete moves to the contact surface from which he makes the jump, so the time of his movement on the playing court from the starting place to the place of the jump is determined. Performing repulsion from the contact surface, after a certain period of time, one of the light signaling devices with a touch sensor located on the scoreboard gives a light signal (simulating the direction of the ball during an attacking strike). The athlete touches with his hands to this light signaling device with a touch sensor, the response time of the athlete is fixed by the signal processing unit to perform all the protective technical and tactical actions as a whole. All signals are sent through electric wires from the signal processing unit to the light signaling devices with a visual display of information on the monitor about the training process.

A control device for the technical and tactical actions of volleyball players in defense, consisting in the fact that over the game net, along its entire length, there is a panel containing equally light start signaling devices, one of which in an arbitrary order signals the athlete about the start of movement, also on both sides of a playground, motion sensors are placed, having wireless communication between each other in the form of a beam, at the intersection of which the athlete determines the start time of his movement to the panel, and the motion sensors with are united by means of electrical wires with a signal processing unit, and a contact surface is placed directly near the game net, connected via electric wires to a signal processing unit, in addition to the panel there are light signaling devices with touch sensors, when one of the triggered signaling device with a touch sensor is touched, the signal from electric wires from the panel enters the signal processing unit, also connected by electric wires to a monitor that displays information about the training process.

The invention is illustrated by figure 1, which shows a device for monitoring the technical and tactical actions of volleyball players in defense, where: 1 - signal processing unit; 2 - electric wires; 3 - start warning light; 4 - panel; 5 - contact surface; 6 - motion sensors; 7 - light signaling device with a touch sensor; 8 - monitor.

During the training of the technical and tactical actions of the defense players aimed at improving the single blocking through the signal processing unit, a signal is sent to one of the start warning lights located on the panel. This signal is displayed in the form of an intermittent light signal informing the athlete about the start of movement, in addition, the time begins to determine the response of the athlete to this signal. The athlete, moves along the playing court, towards the triggered light start signaling device, crosses the light beam propagating between two motion sensors placed on both sides of the playing court. The motion sensors are connected via an electric wire to the signal processing unit, and therefore, the intersection of the beam by the athlete provides a fixation of his reaction time to the signal of the triggered light signaling device. Moving to the grid, near which there is a contact surface, designed to fix the time of the athlete's movement from the starting position to the place of the jump (from the contact surface), the signal from it is transmitted via electric wires to the signal processing unit. At the time of the jump, one of the light signaling devices with a touch sensor located on the panel with a certain time interval (delay) from the signal processing unit receives a signal simulating the direction of the opponent's attacking strike. The athlete, in the flight phase, blocks the direction where the light signaling device with the touch sensor worked, touching it.

The signal about the touch of the triggered light signaling device with the touch sensor by hands is also transmitted to the signal processing unit, followed by visualization on the monitor in the form of numerical data on the results of the training (the response time of the athlete to the start light signaling, the time the athlete moves from the starting position on the playing court to the contact the surface where repulsion is made when jumping, the time it touches the light annunciator with a touch sensor).

The operation of the device. The signal processing unit 1 generates a signal in a random order, transmitting it through the electric wires 2 to the start light 3 located on the panel 4. The athlete moves to the contact surface 5, crossing the beam propagating from the motion sensors 6 connected to the signal processing unit 1 by means of electric wires 2 Based on the contact surface 5, the signal is transmitted via wires 2 to the signal processing unit 1, from which, with a certain delay in time, the signal is transmitted to one of the light signaling devices moat with touch sensor 7. An athlete with regard to the indicator light touch sensor 7 and a signal from it is transmitted by electrical conductors 2 and then displays the signal processing unit 1 on the monitor 8.

Thus, the simulator allows you to control the technical and tactical actions of the players in defense, with the simulation of various game situations, to conduct an objective assessment of their level of preparedness when performing a single block, which allows the coaching staff to identify shortcomings and promptly make adjustments to the training process individually for each player, to carry out quality control of the training process as a whole.
