Abstract

Supplemental Digital Content is Available in the Text. ABSTRACT The effects of caffeine mouth rinse (Caff-MR) on sports performance have been evaluated by recent studies presenting contrasting results. Therefore, this systematic review aimed to summarize the evidence regarding the effects of Caff-MR on sports performance. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations, the search through PubMed, Web of Science, and Scopus databases was performed until December 2021. A random-effects meta-analysis of standardized mean differences was performed to assess the overall effect of Caff-MR on sports performance-related outcomes. Sixteen studies met the inclusion criteria (207 participants). The meta-analysis showed no significant overall effect of Caff-MR on sports performance (p = 0.09). Moreover, no effects were shown on maximal heart rate or ratings of perceived exertion. The risk of bias for the included studies assessed using the risk of bias in randomized trials Cochrane tool presented 87.5% (n = 14) of the studies as medium and 12.5% (n = 2) as high scores. These data do not support using Caff-MR for sports performance, although more consistent and well-controlled studies are warranted. Large heterogeneity in study designs precludes making practical recommendations for exercise performance. More research is warranted to elucidate the potential of Caff-MR, specifically focusing on determining the optimal dose.

吐出来：咖啡因漱口液是一种有效的刺激剂吗？系统综述与荟萃分析

文本中提供了补充数字内容。最近的研究对比了咖啡因漱口液对运动成绩的影响。因此，本系统综述旨在总结Caff MR对运动成绩影响的证据。根据系统评价和荟萃分析的首选报告项目建议，在PubMed、Web of Science和Scopus数据库中的搜索一直进行到2021年12月。对标准化平均差异进行随机效应荟萃分析，以评估Caff MR对运动成绩相关结果的总体影响。16项研究符合纳入标准（207名参与者）。荟萃分析显示，Caff MR对运动表现没有显著的总体影响（p=0.09）。此外，对最大心率或感知用力评分也没有影响。使用随机试验中偏倚风险评估的纳入研究的偏倚风险Cochrane工具显示87.5%（n=14）的研究为中等，12.5%（n=2）为高分。这些数据不支持使用Caff MR进行运动表现，尽管有必要进行更一致和控制良好的研究。研究设计的巨大异质性阻碍了对运动表现提出切实可行的建议。需要更多的研究来阐明Caff MR的潜力，特别是集中在确定最佳剂量上。
