A new study suggests that an amino acid contained in watermelons — and therefore in their
The study was published July 17 in the Journal of Agricultural Food Chemistry. Watermelon's ability to help ease muscle soreness after exercise is attributed to the amino acid L-citrulline.An hour before an exercise session, the researchers gave study participants watermelon juice, watermelon juice with added L-citrulline, or a juice without L-citrulline. In both watermelon juice tests, the participants had less muscle soreness 24 hours after exercising.
There was no difference between plain watermelon juice and watermelon juice with added L-citrulline. That means the L-citrulline naturally present in the watermelon seemed to work better than the added amino acid.
They were also able to determine how much of the amino acid would have made it into the
Previous studies have shown that watermelon juice also contains antioxidants, and seems to increase muscle
