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.

背景——体育运动是一个广泛的领域，对技艺的精湛表现而言，它要求运动员进行刻苦的练习；此外，运动员始终以目标为导向，并投入大量的精力以争取胜利。这种压力和情感上的困扰导致竞技前的焦虑，进而影响其认知表现。
目的——本研究的首要目标是评估经颅直流电刺激（tDCS）对大学生运动员竞技前焦虑和认知表现的影响。
方法/设计——本研究为一项随机对照试验，双组单中心研究。将使用贝克焦虑量表（BAI）、斯托罗普颜色测试、数字符号替换测试和生物反馈分析（EMG）在干预前后评估焦虑和认知水平。实验组和对照组将接受连续10天的tDCS治疗。随访评估将通过焦虑和认知量表的后测值以及生物反馈分析进行。
结果——实验组内的组内分析显示，贝克焦虑量表测试、斯托罗普测试、DSST测试和EMG生物反馈的P值均小于0.05。组间分析中存在显著差异，斯托罗普测试、DSST测试和EMG生物反馈的后测值均小于0.05。
结论——我们得出结论，tDCS对大学生运动员的竞技前焦虑和认知表现具有积极影响。通过使用先进的技法，即经颅直流电刺激（tDCS），可以控制焦虑和认知，这是一种用于提高运动表现的安全神经刺激过程。
