Unilateral left hand contractions (LHCs) have been used as a neurophysiologically motivated intervention for optimizing and stabilizing a wide range of behaviors, including motor performance. What is currently unknown however is the efficacy and neurophysiological basis of LHC interventions. The aim of this systematic meta-analysis was to review and synthesize the evidence on the effectiveness of LHCs, as a pre-performance routine, on motor performance. We, therefore, discuss the theoretical background, highlights key methodological considerations, and suggest areas of future research. An electronic search of the PubMed, PsycInfo, Google Scholar, Scopus, and SPORTDiscus databases was conducted to identify peer-reviewed literature relating to LHCs and motor performance, skilled performance, peak performance, and choking. Ten studies (12 effect sizes) met inclusion criteria and were retained for quality assessment and synthesis. The findings indicate a moderate effect of LHC interventions on performance (g = 0.59, 95% CI = 0.14, 1.03); further, moderator analyses revealed that the effect was significant in experimental design studies, among sub-elite and elite athletes, and when participants were exposed to high-pressure situations. A trim-and-fill analysis was conducted to estimate and correct any potential publication bias, and the results suggest the effect of the LHC intervention may not be as robust as initially appeared. We conclude that this moderate effect should be interpreted with caution. Specifically, concerns regarding study quality and lack of neurophysiological specificity appear to limit the impact and significance of the LHC literature as it currently stands.

单侧左手收缩（lhc）已被用作一种神经生理学动机干预，用于优化和稳定广泛的行为，包括运动表现。然而，目前尚不清楚LHC干预的疗效和神经生理基础。本系统荟萃分析的目的是回顾和综合lhc作为运动前常规训练对运动表现的有效性的证据。因此，我们讨论了理论背景，强调了关键的方法考虑，并提出了未来研究的领域。对PubMed、PsycInfo、b谷歌Scholar、Scopus和SPORTDiscus数据库进行电子检索，以确定与lhc和运动表现、熟练表现、峰值表现和窒息有关的同行评审文献。10项研究（12个效应量）符合纳入标准，并保留用于质量评估和综合。研究结果表明，LHC干预对成绩有中等影响（g = 0.59, 95% CI = 0.14, 1.03）；此外，调节因子分析显示，在实验设计研究中，在亚精英运动员和精英运动员中，以及当参与者暴露于高压环境时，这种影响是显著的。为了估计和纠正任何潜在的发表偏倚，进行了一项修正分析，结果表明LHC干预的效果可能不像最初出现的那样强大。我们的结论是，这种适度的影响应该谨慎解释。具体来说，对研究质量和缺乏神经生理学特异性的担忧似乎限制了LHC文献目前的影响和意义。
