Abstract
Background and purpose: In recent years, brain stimulation using transcranial direct current stimulation (tDCS) has provided promising findings to researchers. The purpose of this study was to investigate the effects of one session of tDCS on the mental fatigue of Skilled basketball players.
Methods: This study was semi-experimental method which was carried out using two groups with pre-test and post-test design. For this purpose, 18 male right handed skilled basketball players (mean age ± SD = 22±3) were selected through convenience sampling method. At first, participants reached lower levels of mental fatigue using Stroop software and mathematical equations. Then were randomly divided into two groups of anodal (n1=9) and sham (n2=9). The experimental group received F3 area stimulation with the 1.5 mA current for 25 minutes in the one session. While this intervention was not provided to the sham group. Before and after the application of tDCS, participants completed the Visual Analog Scale (VAS).
Results: The results showed there was no significant difference between the experimental and control groups in the report of mental fatigue scores. In fact, the scores of mental fatigue in two groups represented degree of similar changes and no significant effect was observed in the experimental group after the application of tDCS (P<0.05).
Conclusion: The results of this study showed that using tDCS did not have a significant effect on basketball players' mental fatigue. In other words, the results showed that the use of a single tDCS did not affect the mental fatigue of basketball players. It is suggested that multi-session protocols be used in future studies.
