Exercise performance is influenced by many physical factors, such as muscle strength and endurance. Particularly in the physical fitness and sports performance contexts, there are many types of ergogenic aids to improve muscular strength and endurance performance, with non-athletes and even athletes using illegal drugs to reach the top. Thus, the development of innovative methods to aid in exercise performance is of great interest. One such method is transcranial direct current stimulation (tDCS). A systematic search was performed on the following databases, until January 2019; PubMed/MEDLINE, SCOPUS, and Pedro database. Studies on tDCS for muscular strength and endurance performance improvement in non-athletes and athletes adults were included. We compared the effect of anodal-tDCS (a-tDCS) to a sham/control condition on the outcomes muscular strength and endurance performance. We found 26 controlled trials. No trial mentions negative side effects of the intervention. The data show differences between the studies investigating muscle strength and the studies evaluating endurance, with regard to successful use of tDCS. Studies investigating the efficiency of tDCS on improving muscular strength demonstrate positive effects of a-tDCS in 66.7% of parameters tested. In contrast, in studies evaluating the effects of a-tDCS on improving endurance performance the a-tDCS revealed a significant improvement in only 50% of parameters assessed. The majority of the data shows consistently influence of a-tDCS on muscular strength, but not to endurance performance. The results of this systematic review suggest that a-tDCS can improve muscular strength, but not to endurance performance.
运动表现受多种身体因素影响，如肌肉力量和耐力。特别是在体能和运动表现方面，有多种提高肌肉力量和耐力表现的促力辅助手段，非运动员甚至运动员都使用非法药物来达到巅峰。因此，开发有助于提高运动表现的创新方法备受关注。经颅直流电刺激（tDCS）就是这样一种方法。截至2019年1月，我们在以下数据库进行了系统检索：PubMed/MEDLINE、SCOPUS和佩德罗数据库。纳入了关于tDCS对非运动员和成年运动员肌肉力量和耐力表现改善的研究。我们比较了阳极tDCS（a-tDCS）与假刺激/对照条件对肌肉力量和耐力表现结果的影响。我们找到了26项对照试验。没有试验提及干预的负面副作用。数据显示，在tDCS的成功应用方面，研究肌肉力量的研究与评估耐力的研究之间存在差异。研究tDCS提高肌肉力量效率的研究表明，在66.7%的测试参数中，a-tDCS有积极作用。相比之下，在评估a-tDCS对提高耐力表现影响的研究中，a-tDCS仅在50%的评估参数中显示出显著改善。大多数数据一致表明a-tDCS对肌肉力量有影响，但对耐力表现没有影响。该系统评价的结果表明，a-tDCS可以提高肌肉力量，但对耐力表现没有作用。
