摘要

研究目的本系统综述和荟萃分析的目的是评估咖啡因(CAF)摄入策略对运动后恢复期心率变异性(HRV)指数的影响,同时考虑其形式、时间和剂量:该荟萃分析符合系统综述和荟萃分析首选报告项目(PRISMA)指南,并已在 PROSPERO 数据库(CRD42023425885)中注册。我们在 MEDLINE、Web of Science、LILACS 和 SCOPUS 上进行了全面的文献检索,并于 2023 年 5 月结束。我们主要研究了在 18 岁及以上的活跃成年人中,比较 CAF 补充剂和安慰剂对运动后心率变异指数影响的随机临床试验。主要终点是评估心率变异指数,在运动前和运动后均进行测量:结果:在纳入的 10 项研究中,7 项用于荟萃分析,所有研究都为系统综述做出了贡献。这些研究探索了多种 CAF 策略,包括不同的形式(胶囊、饮料、口香糖)、时间(10、45、60 分钟)和剂量(2.1 至 6.0 毫克/千克)。结果显示,安慰剂和 CAF 条件下的相邻 RR 间期连续平方差平均值的平方根(RMSSD)(标准化平均差(SMD)-0.03,95% CI -0.265 至 0.197,p=0.77)和高频(HF)指数(SMD -0.061,95% CI -0.272 至 0.150,p=0.57)均无实质性差异。此外,采用固定效应模型并考虑 CAF 施用剂量的元回归分析表明,咖啡因剂量与心率变异指数之间没有显著相关性(P>0.05):总之,有中等确定性的证据表明,不同的咖啡因摄入策略(包括形式、时间和剂量等方面)对运动后心率变异指数的恢复(即迷走神经调节)没有显著影响。

Impact of Caffeine Intake Strategies on Heart Rate Variability during Post-Exercise Recovery: A Systematic Review and Meta-Analysis.

Objectives: The objective of this systematic review and meta-analysis is to evaluate the influence of caffeine (CAF) intake strategies, taking into account their form, timing, and dosage, on heart rate variability (HRV) indices in the post-exercise recovery period.

Methods: The meta-analysis adhered to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and is registered in the PROSPERO database (CRD42023425885). A comprehensive literature search was carried out across MEDLINE, Web of Science, LILACS, and SCOPUS, concluding in May 2023. We concentrated on randomized clinical trials comparing CAF supplementation effects to placebo on HRV indices post-exercise in active adults aged 18 and above. The primary endpoint was the assessment of HRV indices, measured both prior to and following exercise.

Results: Of the 10 studies included, 7 were used for the meta-analysis, and all contributed to the systematic review. The research explored a variety of CAF strategies, spanning different forms (capsule, drink, gum), times (10, 45, 60 min) and doses (2.1 to 6.0 mg/kg). The outcomes revealed no substantial variations between the placebo and CAF conditions in terms of both the square root of the average of successive squared differences between adjacent RR intervals (RMSSD) (standardized mean difference (SMD) -0.03, 95% CI -0.265 to 0.197, p=0.77) and high frequency (HF) index (SMD -0.061, 95% CI -0.272 to 0.150, p=0.57). Furthermore, metaregression analysis, employing a fixed-effects model and accounting for the administered CAF doses, revealed no significant correlation between caffeine doses and HRV indices (p>0.05).

Conclusion: In conclusion, there is moderate-certainty evidence suggesting that different CAF intake strategies, encompassing aspects such as form, time, and dose, do not have a significant impact on HRV indices recovery post-exercise (i.e., vagal modulation).
