Tart Cherry Juice for Exercise-Induced Muscle Soreness

54 participants

Symptoms Studied

Delayed onset muscle soreness (DOMS) after strenuous exercise, characterized by muscle tenderness, stiffness, reduced range of motion, and strength loss peaking 24-72 hours post-exercise.

Research Hypothesis

Tart cherries contain anthocyanins and polyphenolic compounds with anti-inflammatory and antioxidant properties that may accelerate muscle recovery.

Intervention Tested

Tart Cherry Juice (Montmorency)

355mL (12 oz) Montmorency tart cherry juice twice daily (equivalent to 50-60 whole cherries), for 7 days before and 2 days after exercise

Duration: 7-10 days around exercise event

Study Results

Before Treatment

Healthy runners or athletes engaging in strenuous exercise (e.g., marathon, intense resistance training).

After Treatment

Significantly smaller increase in pain (12mm vs 37mm on VAS, p<0.001). Meta-analysis shows small beneficial effect on muscle soreness (ES=-0.44) and moderate effect on strength recovery (ES=-0.78).

Timeline to Improvement

Protective effects when taken 4-5 days before exercise; recovery benefits in 24-72 hours post-exercise

Side Effects

Generally well-tolerated. Some participants noted improved sleep quality (due to natural melatonin content).

Conclusion

Tart cherry juice reduces exercise-induced muscle soreness and accelerates strength recovery, making it useful for athletes during intense training periods.
