Background- Sports is a wide field which requires intense practice to perform well; moreover athletes are always goal-oriented and put a lot of effort to win. This pressure and emotional distress lead to pre-competitive anxiety which affect their cognitive performance. Purpose- The prime aim of this study is to evaluate the effect of tDCS on pre-competitive anxiety and cognitive performance in collegiate athletes. Method/Design- The experimental study is randomized controlled trial, two group and single centered study. Anxiety and cognitive levels will be evaluated before and after intervention using Beck Anxiety Inventory (BAI) scales, stroop color test, digit symbol substitute test and biofeedback analysis (EMG). The experimental group and control group received tDCS for 10 consecutive days. Follow up assessment will be performance using post value of anxiety and cognitive scales and also by biofeedback analysis. Results- The within group analysis of experiment group revealed P < 0.05 of beck anxiety inventory test, stroop test, DSST-test and EMG biofeedback. There is significant difference in between group analysis, the post value of Stroop test, DSST test and EMG biofeedback are less than0.05. Conclusion- We concluded that the tDCS show positive effect on pre-competitive anxiety and cognitive performance of collegiate athletes. Anxiety and cognition can be controlled by using an advance mode of technique i.e., transcranial direct current stimulation (tDCS) it is the safe neurostimulation process used to improve athletic performance.
