Description

block 12 (athlete), block of stimuli 13. The first electrode 1 is made of a split, zinc, cylindrical shape and consists of the same halves a and b. Strain gages 14 (fmg. 4) are glued on one half. There are eight of them. The strain gauge is a dense rubber frame 15, the diameter of which is wound three turns of constantan wire 16 in the form of a double bifilar winding. A compressive force is applied perpendicular to the plane of the turns (Fig. 4). A key 6 is located in the center of the electrode. Load cells are located between the two halves of the zinc electrode 1 (Fig. 6). The key b is located between two rows of load cells. All eight load cells are connected in series and together with the electric bridge form a converter 3, which serves to convert the compressive force into an electrical signal. Button 17 of key 6 is not in close contact with the opposite half of the first electrode (see Fig. B). The readings are recorded on a measuring device 5, which can have three scales (see Fig. 3). The coil 18 of the start relay 7 is turned on through the normally closed contact of the key 6. After the start relay 7 is activated, the contacts HPi and HP2 are closed and the NC contact is opened (see Fig. B). A zero setting device is necessary to set the arrow to zero before measuring the skin-galvanic resistance. The strain gauge windings are included in one of the arms of the electric bridge, into the diagonal of which an amplifier 4 is included. A switch 11 is necessary to change the measurement mode. The copper electrode 2 is a cylindrical hollow cup. Both electrodes 1 and 2 have the same dimensions and life-size (see Fig. 2 and b). The alarm element 9 may be luminous. Time relay 8 (see Fig. 7) has an additional relay with normally closed and normally open contacts at the output. The block of stimuli 13 is placed in front of the athlete and is a light-sound stimulus. Block 9 and block 13 differ in stimulation intensity and signal frequency. Start relay 7 with three pairs of contacts is shown in FIG. 5.

A device for studying the emotional state operates as follows. The athlete 12 tightly, but without effort, wraps his palm around the copper and zinc electrodes 2 and 1 (see figure 1). Through a normally closed contact of the NC, the zinc 1 and copper 2 electrodes are connected to the measuring device 5.

If the switch 11 is in position 1. then the measuring device 5 registers the dermal-galvanic potential. The registration is carried out on the second scale 5 (see figure 3). Then the athlete makes a strong compression of the zinc electrode 1. In this case, the compressive force P compresses the load cells (see Figs. 4 and 6). When squeezing, the resistance of the constantan Ю wire changes, which is converted by means of a bridge into a voltage change and is amplified by an amplifier 4. Simultaneously with the start of compression of the zinc electrode 1, the key button 6 is pressed. 5 The button is activated and closes its contacts. After closing the key contacts, the voltage is applied to the trigger 7 (see Fig. 1, 5, 6). After that, the NC contact opens and the contacts close

0 HPi and HP2 (see Fig. 1 and 5). Through the HP2 contact, the time relay 8 is turned on and at the same time the stimulus unit 13 is turned on. The athlete is exposed to light and sound stimuli.

5 Therefore, at the time of compression of the zinc electrode 1, the athlete is exposed to light, sound and muscular effort, compressed to the limit of the hand. The compression force is monitored on the first scale of measuring device 5 in Newtons (N). To do this, through the closed contact HPi, the voltage from the amplifier output, proportional to the brush compression force, is supplied to the measuring device 5. After a certain time,

5, for example, after 20 seconds, the time relay 8 is activated and the stimulus unit 13 is turned off. At the same time, the alarm element 9 is turned on and a sound of a different frequency and much lower strength signals 0 to the athlete to stop the compression of the zinc electrode 1 This completes the measurement of the skin-galvanic potential. Therefore, on the middle scale, the initial

5 the value of the skin-galvanic potential, the initial value of the skin-galvanic potential is recorded on the first scale, the compressive force is recorded on the first scale and on the second scale

0, the final value of the skin-galvanic potential is recorded after the block of stimuli is turned off. Then the athlete holds the electrodes for some time until the initial value of the skin-galvanic potential is fully restored. The time to restore potential to the initial level is determined by the clock. This is the end of the experiment. The holding of the electrodes takes place without effort and therefore the button is automatically switched off and the contacts HPi, HP2 and NC return to their original state. Disabling the key occurs simultaneously with the termination of the compression brush of the zinc electrode 1.

Similarly, an experiment is conducted with the registration of skin-galvanic resistance. In this case, the switch 11 is set to position 2. Using the zero setting device 10, the measuring device 5 is set to zero by touching the electrodes 1 and 2 with each other. After setting zero, the electrodes 1 and 2 are disconnected and the athlete tightly but without effort clasps them. The further experiment is carried out similarly.

It should be noted that the key button b is automatically activated when the zinc electrode 1 begins to be compressed. This is because both halves of the zinc electrode 1 approach each other at the time of compression and the opposite half of the electrode presses the key button. Thus, the initial readings, compression force, readings after exposure to the stimulus, and the time at which the readings return to the initial level are recorded. The recovery coefficient is determined. Based on these coefficients and the initial and final readings, a conclusion is made about the emotional state of the athlete.
