The aim of this study was to determine the efficacy of tart cherry (TC) supplementation on recovery following strenuous exercise. A systematic review and meta-analysis were conducted using studies investigating TC supplementation on measures of muscle soreness, muscular strength, muscular power, creatine kinase, C-reactive protein, Interleukin-6, and tumor necrosis factor alpha. A literature search ending in July 2020 was conducted in three databases (SPORTDiscus, Web of Science, and PubMed). Data from 14 studies were extracted and pooled for analysis. Tart cherry supplementation had a small beneficial effect in reducing muscle soreness (effect size [ES] = −0.44, 95% confidence interval [CI] [−0.87, −0.02]). A moderate beneficial effect was observed for recovery of muscular strength (ES = −0.78, 95% CI [−1.11, −0.46]). A moderate effect was observed for muscular power (ES = −0.53, 95% CI [−0.77, −0.29]); a further subgroup analysis on this variable indicated a large effect of TC supplementation on recovery of jump height (ES = −0.82, 95% CI [−1.18, −0.45]) and a small significant effect of supplementation on sprint time (ES = −0.32, 95% CI [−0.60, −0.04]). A small effect was observed for both C-reactive protein (ES = −0.46, 95% CI [−0.93, −0.00]) and Interleukin-6 (ES = −0.35, 95% CI [−0.68, −0.02]. No significant effects were observed for creatine kinase and tumor necrosis factor alpha. These results indicate that the consumption of a TC supplement can aid aspects of recovery from strenuous exercise.

本研究的目的是确定酸樱桃 (TC) 补充剂对剧烈运动后恢复的功效。使用调查 TC 补充剂对肌肉酸痛、肌肉力量、肌肉力量、肌酸激酶、C 反应蛋白、白细胞介素 6 和肿瘤坏死因子 α 的测量的研究进行了系统回顾和荟萃分析。在三个数据库（SPORTDiscus、Web of Science 和 PubMed）中进行了截至 2020 年 7 月的文献检索。提取并汇总了 14 项研究的数据进行分析。酸樱桃补充剂在减轻肌肉酸痛方面具有很小的有益效果（效果大小 [ES] = -0.44, 95% 置信区间 [CI] [-0.87, -0.02]）。观察到对肌肉力量恢复有适度的有益效果（ES = -0.78, 95% CI [-1.11, -0.46]）。观察到对肌肉力量的中等影响（ES = -0.53, 95% CI [-0.77, -0.29]）；对该变量的进一步亚组分析表明，补充 TC 对跳跃高度的恢复有很大影响（ES = -0.82, 95% CI [-1.18, -0.45]），补充对冲刺时间的影响很小（ES = - 0.32, 95% CI [-0.60, -0.04])。观察到 C 反应蛋白 (ES = -0.46, 95% CI [-0.93, -0.00]) 和白细胞介素-6 (ES = -0.35, 95% CI [-0.68, -0.02]) 的影响很小。没有观察到肌酸激酶和肿瘤坏死因子 α 的显着影响。这些结果表明，服用 TC 补充剂有助于从剧烈运动中恢复。对该变量的进一步亚组分析表明，补充 TC 对跳跃高度的恢复有很大影响（ES = -0.82, 95% CI [-1.18, -0.45]），补充对冲刺时间的影响很小（ES = - 0.32, 95% CI [-0.60, -0.04])。观察到 C 反应蛋白 (ES = -0.46, 95% CI [-0.93, -0.00]) 和白细胞介素-6 (ES = -0.35, 95% CI [-0.68, -0.02]) 的影响很小。没有观察到肌酸激酶和肿瘤坏死因子 α 的显着影响。这些结果表明，服用 TC 补充剂有助于从剧烈运动中恢复。对该变量的进一步亚组分析表明，补充 TC 对跳跃高度的恢复有很大影响（ES = -0.82, 95% CI [-1.18, -0.45]），补充对冲刺时间的影响很小（ES = - 0.32, 95% CI [-0.60, -0.04])。观察到 C 反应蛋白 (ES = -0.46, 95% CI [-0.93, -0.00]) 和白细胞介素-6 (ES = -0.35, 95% CI [-0.68, -0.02]) 的影响很小。没有观察到肌酸激酶和肿瘤坏死因子 α 的显着影响。这些结果表明，服用 TC 补充剂有助于从剧烈运动中恢复。
