In Medscape October 22, 2013 news, according to Gayle Nicholas Scott, Clinical Pharmacist at Chesapeake Regional Medical Center, watermelon juice (in theory) may enhance exercise by assisting the body to detox and improve muscle recovery. Watermelon contains citrulline, an antioxidant and pre-cursor to arginine, an amino acid involved in cellular respiration. She states that citrulline was shown to reduce exercise-induced acidosis and research in animals suggests that it may reduce muscle fatigue. Although she suggests that more research is needed on human subjects, she does recommend consuming watermelon after activity to promote wellness. Anyone who has had watermelon on a hot day can’t deny its complete refreshment. Conveniently, Juiceland, down by the trail, makes an awesome watermelon agua fresca.
