The effects of transcranial direct current stimulation on objective and subjective indexes of exercise performance: A systematic review and meta-analysis

摘要: Abstract Objective To examine the effects of transcranial direct current stimulation (tDCS) on objective and subjective indexes exercise performance. Design Systematic review meta-analysis. Data sources A systematic literature search electronic databases (PubMed, Web Science, Scopus, Google Scholar) reference lists included articles up to June 2018. Eligibility criteria Published in journals or repositories with raw data available, randomized sham-controlled trial comparing anodal a sham condition providing (e.g. time exhaustion time-trial performance) rate perceived exertion) Results The initial provided 420 which 31 were assessed for eligibility. Finally, analysis effect sizes comprised 24 studies 386 participants. indicated that tDCS had small but positive performance g = 0.34, 95% CI [0.12, 0.52], z = 3.24, p = .0012. Effects not significantly moderated by type outcome, electrode placement, muscles involved, number sessions, intensity duration stimulation. Importantly, funnel plot showed that, overall, tended be larger lower sample size high standard error. Summary results suggest may have impact However, is probably most likely biased low quality selective publication significant results. Therefore, evidence does provide strong support conclusion an effective means improve
