/Objective: Combining blood flow restriction (BFR) with endurance training is exponentially increasing although the benefits are unclear in trained athletes. We aimed to describe the effects of aerobic and/or anaerobic training programmes combined with BFR on the aerobic capacity and related sport performance of trained athletes.
Databases used were MEDLINE, SPORTDiscus, LILACS, IBECS, CINHAL, COCHRANE, SCIELO and PEDro, through October 2021. For study selection, criteria included (a) clinical trials that recruited trained healthy athletes, that (b) proposed BFR in combination with aerobic/anaerobic training programmes (≥8 sessions) and that (c) evaluated either aerobic capacity or related sport performance. For data extraction, a reviewer extracted the data, and another reviewer independently verified it. The tool RoB 2 (Risk of bias 2) was used to assess risk of bias.
Ten studies met the eligibility criteria, capturing a total of 207 participants. Although it did not reveal any significant effects from training with BFR on aerobic capacity compared to the same training without BFR, effect sizes were extremely high. Subgroup analyses according to the intensity of the training programmes found similar results for low-to-moderate or high-intensity training compared to the same sessions without BFR.
Although adding BFR to training sessions always produce benefits from baseline in aerobic capacity and sport performance of trained athletes, these results are not better than those observed after the same training sessions without BFR. The reduced number of studies, small sample sizes and some concerns regarding risk of bias should be highlighted as limitations.

/目的：尽管血流限制（BFR）与耐力训练相结合的益处尚不清楚，但在训练有素的运动员中，这种结合的使用正在呈指数级增长。我们旨在描述有氧和/或无氧训练计划与BFR相结合对训练有素的运动员的有氧能力和相关运动表现的影响。
使用的数据库包括截至2021年10月的MEDLINE、SPORTDiscus、LILACS、IBECS、CINHAL、COCHRANE、SCIELO和PEDro。研究选择标准包括：（a）招募训练有素的健康运动员的临床试验；（b）提出将BFR与有氧/无氧训练计划（≥8次训练）相结合的试验；（c）评估有氧能力或相关运动表现的试验。数据提取由一名审阅者进行，另一名审阅者独立核实。使用RoB 2（偏倚风险2）工具评估偏倚风险。
10项研究符合纳入标准，共纳入207名参与者。尽管与不使用BFR的相同训练相比，使用BFR训练对有氧能力未显示出任何显著影响，但效应量极高。根据训练计划强度进行的亚组分析发现，与不使用BFR的相同训练相比，低至中等强度或高强度训练的结果相似。
尽管在训练课程中添加BFR总能使训练有素的运动员的有氧能力和运动表现从基线水平上获益，但这些结果并不优于不使用BFR的相同训练课程后的结果。研究数量减少、样本量小以及对偏倚风险的一些担忧应作为局限性予以强调。
