1.The essential branched chain amino acids (BCAA's) include leucine, isoleucine, and valine are of special importance for athletes because they are metabolized in the muscle, rather than in the liver .
2.Theoretically, after digestion once protein is broken down into individual amino acids these amino acids can either be used to build new proteins or be burned as fuel to produce energy.
3.If the athlete's diet is adequate in nutrition then the above "essential" amino acids will be used for protein synthesis which is optimal for advanced human performance.
4.It should also be noted that essential amino acids are not produced in the body such as non-essential amino acids, but rather obtained through proper nutrition.
5.Therefore, it is often theorized that the supplementation of BCAA's are of essential importance to athletes due to their ability to alleviate any deficiencies that the body alone cannot produce.
6.BCAA's have also been known in reducing fatigue in both anaerobic and endurance sports.
7.It has also been noted that leucine may be the most critical BCAA because of its anti-catabolic properties and vital role in protein synthesis。
