Powdered tart cherry supplementation surrounding endurance exercise can decrease muscle damage markers, inflammation, oxidative stress and muscle soreness, while improving performance.
In this study, 27 endurance-trained runners were matched based on their race pace, age, body mass, and fat-free mass. The runners were split into two groups in a double-blind manner: a placebo group given capsules containing 480 mg of rice flour and a tart cherries group given CherryPURE® capsules. These were ingested daily for 10 days, including on the day of the half-marathon and up to 48 hours post-race.
The results showed that runners given tart cherry supplementation completed their half-marathon faster (by 13%) than those given a placebo. Moreover, the tart cherry group had less muscle damage markers over time, a steady increase in antioxidant activity during recovery, 47% lower inflammatory markers, and a 34% lower pre-run soreness in the medial quadriceps compared to the placebo group. These results demonstrate the beneficial effects of tart cherry supplementation on performance and recovery in aerobically trained individuals.
