Delayed onset muscle soreness (DOMS) is a symptom of exercise-induced muscle damage that occurs following exercise. Previous research has indicated that branched-chain amino acid (BCAA) supplementation may attenuate exercise-induced muscle damage that causes delayed onset muscle soreness, however the results are inconsistent. The primary aim of this study was to examine the previous literature assessing the effect of BCAA supplementation on DOMS following an acute bout of exercise in adults. This review was conducted in accordance with PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses), and identified peer-reviewed articles comparing a BCAA supplement to a placebo non-BCAA supplement following an acute bout of exercise. An electronic search of three databases (EbscoHost, Web of Science, and SPORTDiscus) yielded 42 articles after duplicates were removed. All studies included in the current analyis were: 1) peer-reviewed publications; 2) available in English; 3) utilized a random control design that compared a BCAA group to a placebo control group following exercise; 4) and assessed soreness of muscle tissue during recovery. DOMS was assessed in 61 participants following ingestion of a BCAA supplement over the course of these interventions. The cumulative results of 37 effects gathered from 8 studies published between 2007 and 2017 indicated that BCAA supplementation reduced DOMS following exercise training (ES = 0.7286, 95% CI: 0.5017 to 0.9555, p < 0.001). A large decrease in DOMS occurs following BCAA supplementation after exercise compared to a placebo supplement.
延迟性肌肉酸痛（DOMS）是运动引起的肌肉损伤的症状，发生在运动后。先前的研究表明，支链氨基酸（BCAA）补充剂可能会减轻运动引起的肌肉损伤，从而导致延迟性肌肉酸痛，但结果不一致。本研究的主要目的是检查先前评估 BCAA 补充剂对成年人急性运动后 DOMS 影响的文献。本综述是按照 PRISMA 指南（系统评价和荟萃分析的首选报告项目）进行的，确定了比较急性运动后 BCAA 补充剂与安慰剂非 BCAA 补充剂的同行评议文章。通过对三个数据库（EbscoHost、Web of Science 和 SPORTDiscus）进行电子搜索，去除重复项后得到 42 篇文章。目前分析中包含的所有研究均为：1）同行评议出版物；2）英文可用；3）使用随机对照设计，比较运动后 BCAA 组和安慰剂对照组；4）评估肌肉组织在恢复过程中的酸痛程度。在这些干预措施中，61 名参与者在摄入 BCAA 补充剂后评估 DOMS。从 2007 年至 2017 年发表的 8 项研究中收集的 37 项影响的累积结果表明，BCAA 补充剂可减少运动训练后的 DOMS（ES=0.7286，95%CI：0.5017 至 0.9555，p<0.001）。与安慰剂补充剂相比，运动后补充 BCAA 会大大减少 DOMS。
