Abstract：
Some studies showed that a single session of transcranial direct current stimulation (tDCS) has the potential of modulating motor performance in healthy and athletes. To our knowledge, previously published systematic reviews have neither comprehensively investigated the effects of tDCS on athletic performance in both physical and psychological parameters nor investigated the effects of tDCS on high-level athletes. We examined all available research testing a single session of tDCS on strength, endurance, sport-specific performance, emotional states and cognitive performance for better application in competition and pre-competition trainings of national- or international-level athletes. A systematic search was conducted in PubMed, Web of Science, EBSCO, Embase, and Scopus up until to June 2023. Studies were eligible when participants had sports experience at a minimum of state and national level competitions, underwent a single session of tDCS without additional interventions, and received either sham tDCS or no interventions in the control groups. A total of 20 experimental studies (224 participants) were included from 18 articles. The results showed that a single tDCS session improved both physical and psychological parameters in 12 out of the 18 studies. Of these, six refer to the application of tDCS on the motor system (motor cortex, premotor cortex, cerebellum), five on dorsolateral prefrontal cortex and two on temporal cortex. The most sensitive to tDCS are strength, endurance, and emotional states, improved in 67%, 75%, and 75% of studies, respectively. Less than half of the studies showed improvement in sport-specific tasks (40%) and cognitive performance (33%). We suggest that tDCS is an effective tool that can be applied to competition and pre-competition training to improve athletic performance in national- or international-level athletes. Further research would explore various parameters (type of sports, brain regions, stimulation protocol, athlete level, and test tasks) and neural mechanistic studies in improving efficacy of tDCS interventions.

摘要：
一些研究表明，单次经颅直流电刺激（tDCS）具有调节健康和运动员运动表现的潜力。据我们所知,先前发表的系统评价既没有全面调查tDCS对身体和心理参数运动表现的影响，也没有调查tDCS对高水平运动员的影响。我们检查了所有可用的研究测试，耐力,运动特定的表现，情绪状态和认知表现，以便更好地应用于国家或国际水平运动员的比赛和赛前训练。在PubMed进行了系统的搜索，WebofScience,EBSCO,Embase,和Scopus直到2023年6月。当参与者至少在州和国家级比赛中有运动经验时，研究就有资格。在没有额外干预的情况下接受了一次tDCS，对照组接受假tDCS或不接受干预。从18篇文章中纳入了20项实验研究（224名参与者）。结果表明，在18项研究中，有12项研究中，一次tDCS会话改善了身体和心理参数。其中,六指TDCS在运动系统上的应用(运动皮层，运动前皮质,小脑)，五个在背外侧前额叶皮层，两个在颞叶皮层。对tDCS最敏感的是力量，耐力,和情绪状态，提高了67%，75%,75%的研究，分别。不到一半的研究表明，运动特定任务（40％）和认知表现（33％）有所改善。我们建议tDCS是一种有效的工具，可用于比赛和赛前训练，以提高国家或国际水平运动员的运动成绩。进一步的研究将探索各种参数(运动类型，大脑区域,刺激方案，运动员水平,和测试任务)和提高tDCS干预效果的神经机制研究。系统审查注册：https://www。crd.约克。AC.uk/prospro/display_record.php?ID=CRD4202236989，标识符CRD4202236989。
