A secret ingredient discovered in the fresh juice extracted from watermelon could be a new super recovery drink.
Researchers at the Technical University of Cartagena, Spain, tested two groups of cyclists over a series of endurance drills and measured their recovery rates. Before exercising, one group was given a pink placebo drink, the other group watermelon juice. Those who drank the melon juice felt a lot less sore the following day according to the follow-up studies.
The secret lies in an active ingredient, L-citrulline. Although some compound drinks use this as an additive, the research team said the results were more remarkable after it was supplied more naturally through unpasteurised watermelon juice.
The results suggest that L-citrulline has antioxidant properties and may improve athletic performance and speed up the removal of lactic acid from muscles, allowing more intense training and faster recovery. The experts concluded that it’s better to drink unpasteurised watermelon juice than to take an L-citrulline supplement.
