Nitric Oxide is a chemical that is produced in the nose when air moves through it. Not to be confused with nitrous oxide, nitric oxide is regularly referred to by its initials, NO. This nasal generated chemical has become a recent fad in the fitness community because of its proven health benefits.
When nitric oxide is created in the nasal passages it travels with the oxygen that you are breathing in. The nitric oxide that enters your body helps to dilate blood vessels resulting in reduction of blood pressure. Dilating the vessels makes it easier for your blood to travel throughout your body to the muscles that need it to function
Naturally, Nitric Oxide also lowers your blood pressure. Because the blood vessels are dilated, the blood can move freely through them. Hence the present fad in the term “NO” that athletes are talking about. If your blood is moving easier and delivering the muscles what they need, your endurance and ability to perform will automatically increase. This also gives the athlete a leg up on the competition without having to use chemicals. The more air that comes through your nose, into the body, the better you will be able to perform.
