Tart cherry concentrate has been shown to improve muscle function, and reduce muscle damage, oxidative stress/inflammation, and muscle soreness in athletes; however, evidence for acute endurance performance benefits is scarce. The purpose of this review was to evaluate the effect of tart cherry juice on endurance exercise performance with a meta-analysis. Data sources included Medline, Embase, Web of Science, and Google Scholar. Eligibility criteria were randomized controlled trials with endurance exercise performance tests. Participants were healthy individuals. Interventions included tart cherry supplementation and placebo ingested before, and/or on the day of exercise. Ten studies were included (totaling 127 males and 20 females). Standardized mean differences (SMD) with 95% confidence intervals were calculated for each study and pooled effects were assessed. Tart cherry concentrate in juice or powdered form, ingested for 7 days to 1.5 hours before exercise performance testing significantly improved endurance exercise performance (SMD: 0.36; 95% CI: 0.07 to 0.64; = 0.01; = 0%) upon pooling of the ten studies. Tart cherry concentrate has a significant benefit for endurance exercise performance. Key teaching pointsTart cherry concentrate has a significant benefit for endurance exercise performance.Tart cherry concentrate may enhance endurance exercise performance via its low glycemic index, anti-inflammatory and anti-oxidative capacity, and blood flow enhancing effects.
酸樱桃浓缩物已被证明可以改善肌肉功能，减少运动员的肌肉损伤、氧化应激/炎症和肌肉酸痛；然而，关于其对急性耐力表现的益处的证据很少。本综述的目的是通过荟萃分析评估酸樱桃汁对耐力运动表现的影响。数据来源包括 Medline、Embase、Web of Science 和 Google Scholar。纳入标准为具有耐力运动表现测试的随机对照试验。参与者为健康个体。干预措施包括在运动前和/或运动当天摄入酸樱桃补充剂和安慰剂。纳入了 10 项研究（共包括 127 名男性和 20 名女性）。计算了每项研究的标准化均数差值（SMD）和 95%置信区间，并评估了汇总效果。在运动表现测试前 7 天至 1.5 小时内摄入酸樱桃浓缩物的果汁或粉末形式，显著提高了耐力运动表现（SMD：0.36；95%CI：0.07 至 0.64； = 0.01； = 0%）。酸樱桃浓缩物对耐力运动表现有显著的益处。主要教学要点酸樱桃浓缩物对耐力运动表现有显著的益处。酸樱桃浓缩物可能通过其低血糖指数、抗炎和抗氧化能力以及增强血流的作用来提高耐力运动表现。
