Primary

Measure	Time frame
Changes in bimanual coordination. Timepoint: Measurement of bimanual coordination at the beginning of the study in the first week (before the start of the intervention), measurement of bimanual coordination 20 minutes after stimulation, measurement of bimanual coordination one week after the first intervention and before the sham intervention in the second week, measurement Bimanual coordination 20 minutes after sham intervention (unrealistic stimulation) in the second week. Method of measurement: Lafayette company's two-handed coordination tool.;Reaction Time. Timepoint: Measurement of reaction time at the beginning of the study in the first week (before the start of the intervention), measurement of reaction time 20 minutes after stimulation, measurement of reaction time one week after the first intervention and before sham intervention in the second week, measurement of reaction time 20 minutes after From sham intervention (unreal stimulation) in the second week. Method of measurement: Reaction time device Response Panel (63035A, Lafayette, Indiana).;Working memory. Timepoint: Measurement of working memory at the beginning of the study in the first week (before the start of the intervention), measurement of working memory 20 minutes after stimulation, measurement of working memory one week after the first intervention and before sham intervention in the second week, measurement of working memory 20 minutes After sham intervention (unreal stimulus) in the second week. Method of measurement: Stroop word-color test.;Rate of perceived pressure (RPE). Timepoint: During the execution of sub-maximal endurance activity, every 3 minutes, the level of perceived pressure is announced and recorded by the subjects. The average pressure perception in each training session is calculated and used for analysis. Method of measurement: From the image of the Borg scale (0 – 100; RPE).;Feeling scale to measure the feeling of pleasure (perceptual response). Timepoint: During the perfo	—
