L-Citrulline in watermelon juice helps to increase muscle mass, improve athletic performance and relieves muscle pain after exercise, a study published in the Journal of Agricultural and Food Chemistry.
The team of Dr. Aguayo Encarta explains this huge benefit of watermelon juice for athletes with the following facts: in 100 grams of watermelon juice contains 8.1 milligrams of vitamin C, 4,532 micrograms of lycopene and 303 milligrams betakaroten - powerful antioxidants that prevent damage DNA and protect tissues from cancer.
Contained L-citrulline is not of the vital amino acids, because it is synthesized in the body - in the small intestine. When ingested with food, however, the compound is converted into L-arginine and nitric oxide.
Citrulline and arginine are important for the vasodilatation - the widening of blood vessels, particularly the large arteries and veins. Nitric oxide is used of smooth muscle that relaxes under his influence. This as a result leads to ease the operation of the blood vessels, and improves circulation.
Nitric oxide maintains the elasticity of the vessel walls, facilitating the prevention of hypertension. When the cardiovascular system is running optimally, the likelihood of developing a blood clot, leading to a stroke or heart attack, fell significantly, and the supply of muscle tissue with nutrients and oxygen is the most favorable for its calming, strengthening and growth.
The additional benefit of citrulline is that associated with the ammonia in the liver, and outputs it from the body. The ammonia can be toxic to the liver. Accumulates not only in poisoning, but also in poor nutrition, combined with strenuous physical exercise.
The team of Dr. Aguayo conducts their research involving two groups of athletes, some of which consume drinks artificially enriched with L-citrulline, the other - fresh watermelon juice. Six months later, both groups showed improvements on most parameters monitored, but in the second group, they are considerably more pronounced.
The researchers carried out a number of tests: endurance and strength, and blood tests are positive - L-Citrulline of fresh watermelon juice is absorbed much better than from dietary supplements. This is due to its high bioavailability - as such, adjuvants are used by the body more easily and efficiently.
