The effectiveness of direct electrical stimulation of the brain from the visual cortex on the reaction time of skilled soccer players

Introduction: The purpose of the present study is to stimulate transcranial direct current from the visual cortex on the reaction time of skilled soccer players.

Research method: The current study is a semi-experimental study with a pre-test-post-test design. The statistical population of this study was the skilled male football players of Tehran province in 1401, 36 of them were selected by available sampling and randomly divided into 3 groups: visual cortex stimulation (12), sham stimulation (12) and control (12). became The direct transcranial electrical stimulation intervention was such that the electrodes are placed in the Oz anode and Cz cathode in the stimulation of the visual cortex. In order to analyze the data, descriptive statistics methods were used to calculate the central and dispersion indices, and the Shapiro-Wilk test was used to check the normality of the data. Correlated t-test was used to independently examine the variables in the investigated groups. Data analysis was done using SPSS version 24 statistical software at a significance level of 0.05.

Findings: The results showed that the average reaction time after electrical stimulation of ltdcs in the tDCS group of the visual cortex increased from 343.10 ± 57.56 to 347.50 ± 52.40 thousand seconds and according to the significance level of 0.05 the difference It is not significant in this group (P-Value<0.05).

Conclusion: The results showed that electrical stimulation of the visual cortex is not effective on the reaction time of skilled soccer players. According to the results, it is suggested to perform electrical stimulation from other areas of the cerebral cortex, especially the primary motor cortex, which is emphasized in the research background.
