Abstract

Objective: This systematic review aimed to assess the effects of caffeine supplements on sleep parameters among professional athletes.

Methods: A systematic search of randomized controlled trials (PROSPERO: CRD42024505377) was performed from 1980 to December 2023 through Web of Science (ISI), Cinahl, Embase, CENTRAL, PubMed/MEDLINE, Scopus, and Scienceopen. The effect of caffeine supplement on all sleep parameters (e.g. duration, quality, insomnia), assessed through objective and subjective methods, was investigated among the athletic community.

Results: Of 1469 records, nine trials were eligible for the current review. The studies showed varying results concerning sleep quality, quantity, efficiency, number of awakenings, sleep onset latency, and other sleep-related variables. These differences in findings may be attributable to factors such as the timing of caffeine consumption in relation to sleep time and the time of exercise, habitual caffeine use, and the dose of caffeine prescribed. Given the nature of caffeine, insomnia following ingestion is likely to occur.

Conclusions: This review explores the mechanisms by which caffeine influences sleep in athletes. While caffeine supplementation may enhance athletic performance, it could have a detrimental effect on sleep and therefore recovery. It is important that supplementation considers individual responses to caffeine so that it does not adversely affect sleep in this population.

补充咖啡因会影响运动员的睡眠吗？九项随机对照试验的系统回顾

目的：本系统综述旨在评估咖啡因补充剂对职业运动员睡眠参数的影响：本系统综述旨在评估咖啡因补充剂对专业运动员睡眠参数的影响：从 1980 年到 2023 年 12 月，通过 Web of Science (ISI)、Cinahl、Embase、CENTRAL、PubMed/MEDLINE、Scopus 和 Scienceopen 对随机对照试验（PROSPERO：CRD42024505377）进行了系统检索。通过客观和主观方法评估咖啡因补充剂对所有睡眠参数（如持续时间、质量、失眠）的影响，并在运动员群体中进行调查：结果：在 1469 条记录中，有 9 项试验符合本次审查的条件。这些研究在睡眠质量、数量、效率、觉醒次数、睡眠开始潜伏期以及其他睡眠相关变量方面的结果各不相同。这些研究结果的差异可能是由于以下因素造成的：摄入咖啡因的时间与睡眠时间和运动时间的关系、咖啡因的习惯性使用以及咖啡因的处方剂量。鉴于咖啡因的性质，摄入后很可能会出现失眠：本综述探讨了咖啡因影响运动员睡眠的机制。虽然补充咖啡因可能会提高运动成绩，但它可能会对睡眠产生不利影响，从而影响身体恢复。重要的是，补充咖啡因时要考虑到个人对咖啡因的反应，这样才不会对这类人群的睡眠产生不利影响：CRD42024505377。
