Amazing but true… beets and beetroot juice might help to improve your performance, especially for endurance sports such as marathons. In general, the reason for this relates to a compound known as nitric oxide, or NO, which is known for its ability to trigger vasodilation, in other words, NO triggers the relaxation of muscles which in turn increases blood flow in the body.
Until recently, researchers thought NO was only formed by converting the amino acid L-arginine into L-citrulline – and this reaction needs oxygen. Now, during activity, oxygen is in relatively short supply, even more so when the activity is high intensity. And so, no one thought tht NO played much of a role in athletic performance… well, until a second pathway for NO production that doesn’t require oxygen was discovered in the 1990s.
In this second pathway, naturally-occurring nitrate (NO3) from food is converted into nitrite (NO2) – note the spelling – by bacteria in our mouths. Nitrite is then converted to NO in our stomach and beyond, ultimately causing levels of NO in our bloodstream to rise. The key, however, is that this process can occur when oxygen is in short-supply, as would be the case during exercise. And while fruits and vegetables about 60-80% of our nitrate intake (note that nitrate from vegetables does not appear to be associated with cancer risk, as may be the case with cured and preserved meats), beets are one of the richest sources around. ~ NationalPost.com
Long-time natural products industry executive Mark Becker has recently completed his 100th marathon – The Los Angeles Marathon on March 18, 2012. Mark completed the 26.2-mile course from Dodger Stadium to Santa Monica in 5:16:53.
For almost 30 years, Mark has participated in numerous endurance events, including more than 150 triathlons of Olympic distance or longer, 100 marathons and numerous other events including ultra marathons and rough water swims from Alcatraz to the mainland.
“I’ve always taken supplements that increase nitric oxide, explains Mark. “Nitric oxide has had a profound impact on my success because it’s responsible for blood flow, oxygen delivery, glucose uptake and muscle velocity. When I train and race, Nitric Oxide opens the blood floodgates, which promotes increased blood flow and oxygen. This significantly increases my endurance and recovery.”
OXYGEN combines with glucose to create ATP which is the primary energy source for your muscles. Therefore thee more ATP that is available for your muscles, the more powerful and explosive they will be.
On the other hand, when your muscles don’t receive enough OXYGEN to support the amount of exertion you demand, they start producing the lactic acid that causes muscle to fatigue and eventually fail. So the more OXYGEN your muscles receive, the slower the production of lactic acid and the slower the muscles fatigue.
OXYGEN is needed by your body to metabolize lactic acid in the liver AFTER exercise. The more OXYGEN you get into your body POST-exercise, the faster your muscles can recover.
