摘 要:目的:经颅直流电刺激已在临床医学中表现出积极效果,但是其应用于运动生物力学领域的研究尚浅,仍有学者对该技术增强肌肉力量及提升运动表现效果提出质疑。该文系统梳理阳极经颅直流电刺激对肌肉力量的影响及经颅直流电刺激的作用机制。方法:检索PubMed、Web of Science、Google scholar、Scopus数据库,根据纳入与排除标准收集阳极经颅直流电刺激对肌肉力量影响的随机对照试验,使用Cochrane手册对纳入的文献进行质量评价,运用RevMan 5.3软件对数据进行统计分析,效果量统一用ES表示。结果:①阳极经颅直流电刺激对提升肌肉力量水平的总效果量为ES=0.38,95%Cl[0.20,0.57](P<0.05);②阳极经颅直流电刺激应用于各脑区的效果量为ES背外侧前额叶皮质(0.88)>ES_(运动皮质)(0.32)>ES_(颞叶皮质)(0.29);③阳极经颅直流电刺激应用不同电流强度的效果量为ES1.5 mA(0.57)>ES2 mA(0.35);④阳极经颅直流电刺激应用于不同受试对象的效果量为ES运动员(0.64)>ES_(健康人)(0.29);⑤阳极经颅直流电刺激应用于不同任务类型的效果量为ES耐力任务(0.45)>ES力量任务(0.35)。结论:①经颅直流电刺激刺激通过改变大脑皮质兴奋性、调控个体对努力的感知等机制实现对运动员肌肉力量及健康个体与运动员肌肉耐力表现的增强,研究未发现阳极经颅直流电刺激对健康个体最大力量的增益效果。②阳极经颅直流电刺激参数应用策略:增强肌肉力量选取运动皮质、2 mA、10-20 min、极板大小25-35 cm^(2)、单边或双边安置电极;提升肌肉耐力选取背外侧前额叶皮质、运动皮质、10-20 min、极板大小25-35 cm^(2)、单边或联合其他皮质安置电极。③经颅直流电刺激可作为一项神经调控技术应用于运动生物力学领域,但关于其神经生理机制探索仍十分有限,需进一步研究。OBJECTIVE:Transcranial direct current stimulation has shown positive effects in clinical medicine,but its application in sports biomechanics is still at its infant stage.Some scholars still question the effect of this technique on enhancing muscle strength and improving sports performance.This study systematically reviewed the effect of anodal transcranial direct current stimulation on muscle strength and its mechanism.METHODS:PubMed,Web of Science,Google Scholar,and Scopus databases were searched for randomized controlled trials regarding the effect of anodal transcranial direct current stimulation on muscle strength according to inclusion and exclusion criteria.Cochrane Handbook for Systematic Reviews of Interventions was used to evaluate the quality of the included literatures.RevMan 5.3 software was used for statistical analysis,and effect size was uniformly represented by ES.RESULTS:The total effect size of anodal transcranial direct current stimulation on muscle strength level was ES=0.38,95%confidence interval(Cl)[0.20,0.57](P<0.05).The effect sizes of anodal transcranial direct current stimulation on different brain regions were that ES_(dorsolateral) prefrontal cortex(0.88)>ESmotor cortex(0.32)>EStemporal cortex(0.29).The effect sizes of different current intensities on anodal transcranial direct current stimulation were ES1.5 mA(0.57)>ES2 mA(0.35).The effect sizes of anodal transcranial direct current stimulation on different subjects were ESathlete(0.64)>ES_(healthy) person(0.29).The effect sizes of anodal transcranial direct current stimulation on different task types were ESendurance task(0.45)>ES_(power) task(0.35).CONCLUSION:Transcranial direct current stimulation could enhance the muscle strength of athletes and the muscle endurance performance of healthy individuals and athletes by changing the excitability of cerebral cortex and regulating the perception of effort.The study did not find the positive effect of anodal transcranial direct current stimulation on the maximum strength of healthy indiv
