May help relieve muscle soreness
An amino acid found in watermelon, citrulline can reduce muscle soreness, but, apparently, watermelon juice enhances the bio-availability of citrulline. One small study gave athletes plain watermelon juice, watermelon juice mixed with citrulline or a citrulline drink. Both watermelon drinks led to less muscle soreness and quicker heart rate recovery, compared to citrulline on its own.
