Description

The invention relates to sports equipment and can be used by volleyball players.

The purpose of the invention is to increase the effectiveness of training.

The drawing shows a functional diagram of the device.

The device contains a display unit 1, the first 2 and second 3 sensors, a block 4 for measuring time parameters, a block 5 for setting game actions 5, which contains the first 6, second 7, third 8, fourth 9 and fifth 10 switches, catapults 11 and 12, the first 13, second 14, third 15 and fourth 16 gates, first 17, second 18 and third 19 OR elements, first 20, second 21 and third 22 AND elements, NOT 23 element and delay unit 24.

The device works as follows.

The athlete occupies the starting position on the platform under which the first sensor 2 is located. The trainer switches on the device (Start command). In this case, the display unit 1 is triggered and the stopwatches of the time measurement unit 4 are turned on. The indicator is turned on for the athlete to initiate action. The athlete moves to the second sensor 3. At the same time, the first sensor 2 stops one of the stopwatches, which records the time, when the load is removed. When the athlete steps on the pad of the second sensor 3, the second stopwatch stops, which records the total time it takes to perform

When training the speed of the motor reaction followed by the game action, the trainer sets the game situations by turning on the switches of the block 5 of the task of playing actions.

1. When the switch 8 is closed, the signal from the second sensor 3 is fed to the input of the element OR 17 and turns on the catapult 11. When the switch 10 is closed, the signal from the second sensor 3 is fed to the input of the element OR 18 and turns on the catapult 12.

2. When the switch 6 and one of the switches 8 or are closed, the 10 catapults are turned on by the signal generated by the first sensor 2.

3. When the switch 9 or 9 and 6 is closed, the catapults are turned on by the signals formed as follows.

On the Start signal, the valves 14 and 15 are opened, the valve 16 is closed, and the delay unit 24 begins to form a time interval, the delay of which is set relative to the Start signal. If the athlete performed the exercise after turning on the detector faster than the signal is generated by the block 24, the signal from sensor 2 (or 3) passes through the open valve 14 to the OR element 17 and turns on the catapult 11, which fires like a mimicry attacker and the valve 15 is closed in order to prohibit the passage of the signal to the catapult 12 from block 24,

If the signal from one of the sensors enters the input of the valve 14 simultaneously with the signal from block 24, then the valves 14 and 15 with these signals are closed and at the same time, entering the inputs of the AND 22 element. They form a signal that through the OR 17 element turns on the catapult 11 The athlete gets mh for reception from below.

If the signal from block 24 arrives at the input of an open valve 15, at the output of which a signal is opened that opens valve 16. The signal coming from the transmitter through the open valve 16 enters the input of the element OR 18, and a catapult 12 is triggered, which emits m cheat hit

4. When the switch 7 or 7 is closed, and the b catapult are turned on by signals, which, depending on the actions of the athlete, work as follows.

a) The signal from the sensor is earlier than the signal from block 24. Then through the open trigger signal valve 13, the signal from the sensor goes to the first inputs of the elements 20 and 21. Since the specified burden interval has not yet been formed in block 2.4, then from the output of the element NOT 23 to the second input element And 21 at this point also receives a signal. Therefore, at the output of the element 21, a signal is formed, which through the element OR 18 turns on the catapult 12 and through the element OR 19 closes the valve 13. At the moment of arrival of the signal at the input of the element 20 and AND from block 24, the signal at the first input of the element 20 does not exist because the valve 13 is closed.

b) The signal from the sensor arrives simultaneously with the arrival of the signal from block 24. In this case, the output of element 20 forms a signal which, through element OR 17, turns on the catapult 11 and closes valve 13 through element OR 19.

it is necessary in order to prevent the inclusion of the catapult 12 in the event that the signal from the sensor continues and that there is no signal from block 24.

c) The signal from the sensor comes later

than the signal from block 24. In this case, the output element And 21 generates a signal that turns on the catapult 12 only at the time of arrival of the signal from the sensor, since the inputs of the element And 20 signals arrive at different times, and the inputs of the element 21 are simultaneously

The device works as follows.

Responsive training by the method of re-response. The first sensor 2 is located in the zone from which the athlete begins to move at the signal of the indicator. The second sensor 3 is located in

to the zone where the attack of the catapult 11 will be delivered. At the signal of the indicator, the athlete moves with a maximum speed to the zone of the second sensor 3. Depending on the selected manual mode

a catapult 11 or a catapult 12 is turned on. In this case, the trainer can say in advance which one of the catapults is on, or turn them on without informing the athlete.

The athlete is announced the time (s) for which he must move to the zone of the second sensor. Depending on the speed of the operation (tp), one or another catapult is triggered. Moreover, if tp t3,

then the catapult 11 is triggered, and if tp t3, then the catapult 12 is triggered,

In both cases, a simple reaction training will be combined with a selection reaction. Training reaction speed sensory method. The location of the sensors is the same. The training is conducted in three stages.

At the first stage, the practitioner performs the movement, trying to respond to

signal with maximum speed. It moves from the first sensor 2 to the second sensor 3. In this case, the catapult is activated either manually by the trainer or automatically. After each attempt the coach reports

athlete time shown

In the second stage, the task is also performed at the highest speed. But this time the trainer asks the occupant what time he, in his opinion, has fulfilled

motion. The mode of operation of the catapult is set as in the first stage. After that, the athlete reported actual time.

At the third stage, it is proposed to perform the exercise at a different pre-determined speed. If, then the catapult 11 is working, imitating the attack hit. If p t, then the catapult 12 triggers, simulating a fraudulent blow.

Training speed reaction dismembered method. In this case, only the first sensor 2 is used, which is placed in the zone in which the attack hit from the catapult 11 will be carried out. In this case, all the indicated variants of the work of the catarpt are possible.

The device allows you to train the reaction speed and without the work of catapults, which can be used in the first stages of training athletes. The use of catapults allows to train complex reactions with the issuance of urgent information to the athlete on the speed of the action performed, except in cases where this is not required by the method of training. That is, depending on which of the catapults works, the athlete can evaluate his actions.

In all cases of the athlete's action, the coach evaluates the stopwatches of the unit 4 for measuring time parameters.

Claims (1)

The effectiveness of the training is enhanced by a combination of the three methods of fostering responsiveness, since the method of re-response rather quickly yields noticeable results in activities with novice athletes. To improve the motor response, it is necessary to use special methods (dissected, sensory). The proposed device allows the reaction speed to be trained with all three methods. In addition, the development of responsiveness when using the proposed device is carried out under conditions of game action, close to real.
