In a placebo-controlled study on muscle pain in endurance athletes, it was found that tart cherry juice may have attenuated muscle soreness after endurance runs. It is thought that muscle soreness after activity is due to oxidative damage and inflammation. Antioxidants such as those found in tart cherry may help reduce the effects of the oxidative damage and inflammation, thus reducing the associated pain. During the seven-day study, one participant reported some discomfort after consumption of the study beverage and consequently withdrew. There were no other adverse events reported. Researchers advise that results be interpreted cautiously, due to study limitations such as the subjective assessment of pain as reported by participants. Further research is warranted to determine the mechanism of action for the pain and inflammation reduction observed in the study group.
