These three claims are largely based on the assumption that an increase in blood flow to muscle tissue will enable users to experience the claims that supplement companies put forward. Obviously there are many other variable factors that can influence your muscle mass growth and strength gains for example you general diet and training. So the claim is that if your diet and training are in place, taking a nitric oxide supplement will enable your body to build more muscle mass that the same diet and training regime without the nitric oxide supplementation.
There is absolutely no doubt that nitric oxide supplements increase blood flow. Just ask anyone how has taken a nitric oxide supplement and they will tell you blood flow is substantially increased. But does this blood flow actually produce the results that are claimed? Or is it mostly a mental advantage from feeling the pump! Vasodilation Vasodilation is the process of a relaxation of blood vessels, allowing them to carry more blood to and from working muscle tissue.
Vasodilation (to high levels) is triggered by the onset of exercise as the need for oxygen and nutrients is heightened during this time. The process of vasodilation is highly influenced by nitric oxide. High levels of nitric oxide aid in the conversion of an enzyme (GTP) into another (cGMP) which serves as an important messenger to, amongst others, the relaxation of smooth vascular muscle in order to create vasodilatory effects. Therefore, if levels of nitric oxide are inhibited vasodilation may not occur to the extent that allows maximal performance.
In essence, vasodilation occurs when high levels of nutrients need to be transferred into muscles for energy production. Vasodilation itself is highly influenced, and limited by the amount of nitric oxide that is available as it has been observed that a limited production of nitric oxide can lead to vasoconstriction. It can be suggested therefore that if we can enable the body to produce ample amounts of nitric oxide, proper levels of vasodilation can occur, norwegia praca na magazynie enabling the body to transport ample amounts of nutrients to working muscle for maximal power output.
What Should Be Supplemented To Increase Nitric Oxide Levels? Most nitric oxide supplements on the market currently use ingredients such as L-Arginine Arginine-alpha-ketoglutarate L-Citrulline Citrulline Malate As nitric oxide is produced by the conversion of l-arginine it can be supposed that supplementing with l-arginine will have an effect on NO levels. However the evidence as yet shows no correlation between oral arginine supplementation and nitric oxide levels.
Unfortunately l-arginine concentration does not directly affect the rate of nitric oxide production. Citrulline, the amino acid that l-arginine is converted into in the nitric oxide conversion process has actually be shown to have a greater effect of nitric oxide levels with oral supplementation.
