Tart cherry (TC) consumption has become a popular nutritional strategy for recovery, particularly for the attenuation of markers associated with muscle damage. However, there are relatively few studies that have examined an acute dosing strategy. The aim of this pilot study was to explore the feasibility of using powdered Vistula TC for recovery following a bout of muscle-damaging exercise. Twenty-two recreationally active participants (mean ± SD age, stature, and mass were 23 ± 3 years old, 173 ± 10 cm, and 74 ± 17 kg, respectively) performed 40 (5 sets of 8 repetitions) maximal lengthening contractions of the elbow flexors. The participants were randomised to receive either a spray-dried TC extract or a calorie-matched placebo (12 TC, 10 placebo) for 4 days in total, starting on the day of exercise. Dependent measures of maximal voluntary contraction (MVC), muscle soreness (assessed via visual analogue scales; VAS), pain pressure threshold (PPT), range of motion (ROM), and upper arm limb girth were taken at baseline (pre), 24, 48, and 72 h post damaging exercise. There were significant changes over time among all the variables (MVC, VAS, PPT, ROM, and girth, ≤ 0.014). There were no significant differences between the conditions for any of the variables (MVC, VAS, PPT, ROM, and girth, > 0.3). The TC group did not recover at an accelerated rate compared to the placebo. This study provides initial insights into the use of powdered Vistula TC and its effect following strenuous (damaging) exercise bouts. Vistula TC did not improve recovery when taken acutely following a bout of damaging exercise to the elbow flexors.
樱桃（TC）的消费已成为一种流行的营养恢复策略，尤其是对减轻与肌肉损伤相关的标志物有作用。然而，研究其急性给药策略的相关研究相对较少。本初步研究旨在探索使用维斯图拉 TC 粉末在剧烈运动后恢复的可行性。22 名有规律运动的参与者（平均±标准差年龄、身高和体重分别为 23±3 岁、173±10cm 和 74±17kg）进行了 40 次（5 组 8 次重复）最大伸展收缩的肱二头肌。参与者随机接受喷雾干燥 TC 提取物或热量匹配安慰剂（12TC，10 安慰剂），共 4 天，从运动当天开始。依赖于最大自主收缩（MVC）、肌肉酸痛（通过视觉模拟量表评估；VAS）、疼痛压力阈值（PPT）、关节活动度（ROM）和上臂周长在基线（预）、24、48 和 72 小时进行测量。所有变量（MVC、VAS、PPT、ROM 和周长，≤0.014）随时间均有显著变化。两种情况下的任何变量（MVC、VAS、PPT、ROM 和周长，>0.3）均无显著差异。TC 组与安慰剂组相比，恢复速度没有加快。本研究初步探讨了维斯图拉 TC 的使用及其在剧烈（损伤）运动后产生的效果。在剧烈运动后急性服用维斯图拉 TC 对肱二头肌损伤的恢复没有改善作用。
