Effects of watermelon juice on heart recovery and muscle soreness after exercise
Official title: Effects of Watermelon Juice on Heart Rate Recovery and Post-exercise Muscle Soreness
Run by San Diego State University · NCT03380195 · Data updated 2026-11-12
This study tests if drinking watermelon juice helps healthy adults recover their heart rate and reduces muscle soreness after exercise better than Gatorade, sugar water, or plain water.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates how a single dose of watermelon juice, compared to Gatorade, sugar water, and plain water, affects heart rate recovery, blood lactate levels, and muscle soreness 24 hours after exercise. Healthy adults aged 21-50 will participate in the trial, which aims to provide insights into the potential benefits of watermelon juice as a natural recovery aid. Participants will be monitored for changes in heart rate and muscle soreness following their exercise regimen.
Why it matters
Potential benefit: If successful, this study could provide a natural and effective recovery option for athletes and active individuals.
How similar studies have gone: While there is limited research specifically on watermelon juice, similar studies on natural recovery aids have shown promising results.
