Researchers of a new study have found that watermelon juice is very effective in relieving post-exercise muscle soreness.
Fitness experts recommend watermelon juice to people who frequently workout. The health benefit of this summer fruit has now scientific backing after a new study found that the juice is very effective in relieving post-exercise muscle soreness.
"Watermelon juice, naturally rich in l-citrulline, is an excellent option for athletes who want to improve their sports performance," The Telegraph quoted the study authors as saying.
The amino acid L-citrulline present in the fruit is an essential compound in nitric oxide, a gas that widens the blood vessels, and previous studies have also found that a daily dose of watermelon lowers blood pressure, reducing the risk of a stroke or a heart attack.
To test the effectiveness of the juice, exercisers were given either natural watermelon juice, watermelon juice enriched in L-citrulline or a control drink containing no L-citrulline one hour before they exercised. It was found that volunteers who received the first two types of juice experienced relief in muscle soreness after exercising, researchers confirmed in a press release.
Researchers of the study hope that their findings will encourage supplement manufacturers to use these natural ingredients rather than drugs in their products. The scientists say that future research should look at the levels of amino acid required to reduce muscle fatigue and other health benefits in stress, athletic performance, and cardiovascular disease.
"Functional compound contents in fruits and vegetables play a key role in the design of new natural and functional products (beverages, juices, energy bars, etc.) by the food industry instead of synthetic compounds from pharmaceutical industry," the authors concluded.
The study was published online in the Journal of Agricultural and Food Chemistry.
