The participants were subjected to a 15-minute training session, once a day for 5 consecutive days. HTC VIVE Pro (HTC Corporation, New Taipei, Taiwan) goggles and accessories were used. It is specialized equipment consisting of a high-resolution screen goggles and headphones, using an Intel WiGig Wireless connection, and the technology allows for free 360 degrees of movement. The interaction in virtual reality is performed using two controllers held by the player. The movement of the controllers and goggles is tracked by two sensors. The game area covered about 5m2, in the form of a rectangle, determined by the location of motion sensors, as recommended by the manufacturer. The participant received visual information when approaching the boundaries of the game field. A Beat Saber music game was used to conduct training sessions

Participants in the control group did not participate in the training, and were instructed not to perform specific physical activities aimed at improving the examined abilities

A musical game called Beat Saber was used to conduct training sessions. The participant's task was to cut through the blocks of various colors in his direction to the rhythm of music, using two virtual swords. The swords were controlled by the player with controllers of different colors. Blocks had to be cut with a sword whose color matches the block and in the right direction which is indicated by an arrow on the block. The training session consisted of 4 music tracks with different paces and intensities of objects. In addition, during the song, the participant had to avoid objects-objects that randomly appeared in the game scenario - forcing the whole body to move.

Trial Making Test (TMT) A and TMT B were used to assess coordination. This test is a clinical tool for assessing eye-hand coordination. The task of the person tested in the first part (TMT A) was to combine 25 fields in order from the smallest to the largest continuous line. In the second part (TMT B), the subject was to alternate the numbers with the letters of the alphabet according to the formula 1-A, 2-B, 3-C, etc. with a continuous line. The result of the test is the time when the tested person connected all fields in the right order.

The Plate Tapping Test (Reaction Tap Test) is a reaction test using an alternating wall tapping action which measures upper body reaction time, hand-eye quickness and coordination. This test is part of the Eurofit Testing Battery.

During the test, the tester sat on the chair face to face, on the with which he supported his forearm (in the middle of the length). The four fingers of the hand of the examined person were tight and the thumb was visited. The tester held a rod with a diameter of 1.5 cm and length of 50 cm, on which was marked with a centimeter scale. The task of the examined person was to react as quickly as possible to her movement and by clenching the hand grip sticks. The distance from the beginning was measured scale to the point of grasp (bottom edge hands).

The SenseWear Armband was used to assess energy expenditure. The device was placed on the arm of the dominant upper limb. It continuously measured physiological variables through algorithms which determined the number of steps, MET, energy expenditure, and kcal
