BCAA+Amino+Acids--Jessica+and+Yvo

==== First off amino acids are the building blocks of proteins, of these their are nine that are considered essential. "Of the essential amino acids, three account for as much as 33% of muscle tissue – leucine, isoleucine, and valine"(Read, BCAAs Why We Take Them). The liver is responsible for majority serving as a clearinghouse for the amino acids "by monitoring the supply and dictating which amino acids will be transported to which tissues" (Dunford, 161). In which, there is an exception to this which is the branched amino acids- leucine, isoleucine, and valine. Since the live has very low levels of the BCAA enzyme, there needs to be a transfer of amino acids in the tissues, and BCAA transferase is also found in the heart, kidneys, and adipose tissue. The body obtains branched-chain amino acids from proteins found in food, especially meat, dairy products and legumes, but individuals may take powder and pill forms if they prefer. Usually, individuals can purchase BCAAs at any nutrition shop, such as GNC, Vitamin World, etc.. The cost of BCAAs depends on how many servings are in container and the brand of product, for example they can range between $19.99-44.99 just depends the brand and serving size. According to the NCAA, "any athlete who wishes to take BCAAs should consultant athletic trainer to make sure it is not banned because banned substances may not be labeled on nutrition label", but it does not look like it is banned. ====

In one of the articles I founded conducted a study in which they wanted to find out the effects of BCAAs and insulin sensitivity in overweight individuals, and they found that "obesity is associated with elevated plasma levels of certain amino acids (AAs), including the branched-chain AAs (BCAAs), phenylalanine and tyrosine [2–4], their source and contribution to the development of IR remain unclear"(Glynn, 2325). Second article, suggested that “on of the implication of the “central fatigue hypothesis” is that ingestion of BCAA could reduce the exercise-induced increase of brain tryptophan uptake and thus delay fatigue by giving athletes the ability to push on when peripheral fatigue mechanism come into operation” (Hall, 789). The last article, said “Studies on resting human muscle indicate that administration of BCAAs, particularly leucine, has an anabolic effect on protein metabolism either by increasing the rate of protein synthesis or by decreasing the rate of protein degra- dation, or both” (Blomstrand, 270s)

One reason I decided to do this supplement was because I know a lot about it and I am currently taking the powder form. I found a lot of interesting information about this supplement that I didn’t know before which is always a good site. Overall this is was a fun project to do.
