The present systematic review with meta-analysis summarized studies that investigated the effect of carbohydrate (CHO) mouth rinse on muscle strength and muscular endurance. The search was performed in six databases. Thirteen randomized clinical trials were selected and the standardized mean difference between CHO mouth rinse and placebo for maximal strength and muscular endurance was determined via a random-effects model using Review Manager 5.4 software. Meta-regression was also performed to explore the influence of load, number of sets, number of exercises, fasting time, CHO concentration, and number of mouth rinses on the main outcomes. There was no significant effect of CHO mouth rinse on maximal strength (mean difference= 0.25 kg, 95%CI - 1.81 to 2.32 kg, z = 0.24, p = 0.810). However, there was a significant positive effect of CHO mouth rinse on muscular endurance (mean difference = 1.24 repetitions, 95%CI 0.70 to 1.77 repetitions, z = 4.55, p < 0.001). Meta-regression identified that CHO mouth rinse has greater benefits on muscular endurance when using high workloads, multiple exercises, and a smaller number of mouth rinses (p = 0.001). In conclusion, CHO mouth rinse has no effect on maximal muscle strength but has a positive effect on muscular endurance and seems to optimize when fewer mouth rinses, high workloads and numbers of exercises are used.Supplemental data for this article is available online at https://doi.org/10.1080/10408398.2022.2057417.
本项系统评价及荟萃分析总结了调查碳水化合物（CHO）漱口对肌肉力量和肌肉耐力影响的研究。检索在六个数据库中进行。选择了13项随机临床试验，并使用Review Manager 5.4软件通过随机效应模型确定了CHO漱口与安慰剂在最大力量和肌肉耐力方面的标准化平均差异。还进行了meta回归分析，以探讨负荷、组数、练习次数、禁食时间、CHO浓度和漱口次数对主要结局的影响。CHO漱口对最大力量没有显著影响（平均差异=0.25千克，95%CI为-1.81至2.32千克，z=0.24，p=0.810）。然而，CHO漱口对肌肉耐力有显著的积极影响（平均差异=1.24次重复，95%CI为0.70至1.77次重复，z=4.55，p<0.001）。Meta回归分析表明，当使用高负荷、多次练习和较少的漱口次数时，CHO漱口对肌肉耐力有更大的益处（p=0.001）。总之，CHO漱口对最大肌肉力量没有影响，但对肌肉耐力有积极影响，并且当使用较少的漱口次数、高负荷和练习次数时似乎效果最佳。本文的补充数据可在网上获取，网址为https://doi.org/10.1080/10408398.2022.2057417。
