Title:
The Role of Nitric Oxide in Bodybuilding
Word Count:
381
Summary:
Everyone needs nitric oxide to carry out key physiological processes within the body. From a bodybuilder's perspective, nitric oxide supplementation may prove useful in increasing growth due to increases in blood flow to certain areas of the body. Further, men suffering from erectile dysfunction may also find supplementing with nitric oxide helpful.

Article Body:
Nitric Oxide, a key molecule manufacturered by the body, causes vasodilation (an expansion of the internal diameter of blood vessels), which in turn leads to increased blood flow, oxygen transport, delivery of nutrients to skeletal muscle and a reduction in blood pressure. An amino acid compound called arginine alpha-ketoglutarate (A-AKG) and arginine-ketoisocaproate (A-KIC) can boost short term Nitric Oxide levels. Increased strength and markedly improved stamina can also be expected. In fact, the results may be classified into three categories: 1) the promotion of an extended pump; 2) signaling muscle growth and speeding recovery; 3) increasing strength and stamina.
NO2 contains A-AKG and A-KIC, natural myodilators that may help boost nitric oxide levels in your body, thereby increasing blood flow, oxygen transport, and delivery of nutrients to skeletal muscle.
NO2 contains A-AKG and A-KIC which may help your muscles experience an extended pump.
NO2 contains A-AKG and A-KIC which may help your body signal muscle growth and speed recovery.
NO2 contains A-AKG and A-KIC which may help improve your strength and stamina.
NO2 utilizes the A-DS Advanced Delivery System which enhances absorption of the active compounds to insure uptake and help sustain powerful effects around the clock.
Who needs it and what are some symptoms of deficiency?
Everyone needs nitric oxide to carry out key physiological processes within the body. From a bodybuilder's perspective, nitric oxide supplementation may prove useful in increasing growth due to increases in blood flow to certain areas of the body. Further, men suffering from erectile dysfunction may also find supplementing with nitric oxide helpful.
Signs of deficiency include the inability to achieve and sustain erections, physical weakness and extreme fatigue. Most "nitric oxide" supplements contain the amino acid Arginine-alpha-keto-glutarate.
What are the side effects?
With any amino acid containing product, overdose is a possibility. Dosing with too much arginine can lead to diarrhea, weakness and nausea. Clear dosing guidelines have not been established, so it is best to do what is known as "tolerance mapping". Take a small dosage for one week, note the benefits and the side effects, and increase the dosage until the benefits are maximized and the side effects minimized. Over time the two will converge and you will hit the optimal dose.
Benefits
improves strength and stamina
increased muscle growth and recovery
increases muscle pump

Inevitably theres a myth that soy protein is horrible for bodybuilding and that if you are any where near serious about working out or building muscle you will stay away from it. In fact, some sites show studies that soy protein and soy products can be detrimental to your health. And while its true that early claims of soy wonders might not be entirely true, theres also myth that soy protein is bad.
First off, theres a concept called the Biological Value Scale that was developed to measure the quality of specific proteins. It basically rates how efficiently your body will use a given protein source. The higher the BV (biological value), the more amino acids and nitrogen your body is retaining from the foods you eat. In sum, it becomes a way to measure the potential for quality muscle growth and strength.
There was a time when egg whites were at the top of the BV with a score of around 100. Since then, whey proteins have toped out the scales around 106-159 BV. This means that whey protein is better used for quality muscle growth.
But first a warning!
This doesn't mean that all you would utilize is whey protein for all your needs. Many times bodybuilders will use a variety of proteins depending on the BV and the times of day and if they just finished a workout.
Let me explain
Your protein needs in the morning are different then the middle of the day and are different again AFTER a workout and again different before bed.
All this means is that no one protein is the best for any given time. But before I get lost... let me show you the biological value scale in a simple form.
Type of Protein :: Biological Value Rating
Whey: 106-159 Egg: 100 Cows Milk: 91 Fish: 83 Casein: 80 Beef: 80 Chicken: 79 Soy: 74 Wheat Gluten: 54 Kidney Beans: 49
For all these reasons, you can and should see that soy protein is listed lower. That just means its not the most anabolic of proteins for optimal muscle growth.
But dont get me wrong...
This doesn't mean you shouldn't eat soy protein if you enjoy it. It simply means that barring any religious beliefs or personal preferences, soy would not be the ideal protein source for enhanced muscle gains. This doesn't mean you cannot have it or that its bad for you.
In fact, lets continue on with a little example.
John Q. Public 13% body fat 184 lbs 160 lbs of LBM (lean body mass)
For simplification we'll just say that for every LB of LBM (pound of lean body mass) John wants to get 1 g of protein.
John should be consuming 160 g of protein a day.
Heres where the myth and some problems come into play! Read carefully.
If you get a vast amount of your protein from less BV sources then optimal (beans, soy) you will not prime your muscles for optimal anabolic growth. John shouldn't be getting 150+ grams of soy protein a day IF he wants to create the most muscle mass and he has no personal reasons not to use better quality sources.
John also wont be in jeopardy of losing muscle or wasting his efforts if he ingests small quantities of soy proteins because he likes them. Having soy in his cereal is not going to make a difference.
The myth that soy will cause men to produce estrogen is when VAST quantities are ingested. Far beyond what any rational person would want to do on a prolonged basis.
A bodybuilder that has soy will not feel any differences, be any less anabolic then another person who does not consume soy at all.
Fact: A long-term metabolic balance study in young men to assess the nutritional quality of an isolated soy protein and beef proteins (VR Young, A Wayler, C Garza, FH Steinke, E Murray, WM Rand, and NS Scrimshaw) was published in 1984 by the American Journal of Clinical Nutrition. Am. J. Clinical Nutrition, Jan 1984; 39: 8 - 15.
After 84 days of two groups, one totally isolated soy protein and the other on beef proteins, found a conclusion that:
"Body cell mass measurements did not reveal any deterioration in protein nutritional status. These observations confirm the prediction, derived from previous short-term nitrogen balance studies, that the nutritional quality of isolated soy protein is high and that this plant protein can serve as the sole source of essential amino acids and nitrogen for protein maintenance in adults."
So let me summarize and review...
Soy is not the most biological available source for optimal anabolic muscle growth. If you were to finish a workout, you would want to ingest some high quality whey protein vs. soy proteins. However, simply having soy doesn't mean its bad for bodybuilding unless you are getting a majority of your protein from soy products. Then its not optimal. Youd also need to ingest quite a bit on a daily basis for any negative effects of soy to manifest (specifically aimed at males in this sentence).
