The role of major amino acids in sports nutrition

Abstract
Amino acids that build up proteins are given special attention in sports nutrition, but they also play important roles in a number of other physiological functions, including enhanced brain functions, memory and concentration. Industrial production methodes of amino acids fall into three classes: protein hydrolysates, fermentation processes and chemical synthesis resulting in isolated amino acids or isolated amino acid residues.
Amino acids consumption can cause special effects in our body. Branched chain amio acids (BCAA) supplementation can moderate exercise-induced muscle damage and cause reduction in creatine kinase (CK) efflux.
Glutamine is involved in detoxification of ammonia, so it promotes muscle regeneration and plays a major role in immune system function.
Arginin and citrullin enhance NO, through their vasodilating effect can assist oxigen and nutrition transport, enhance skeletal muscles metabolism, thus delay fatigue.
Tyrosine is also known as an antidepressant amino acid because it has stress reducing effect.
HMB in calorie-deficient conditions can reduce lean body weight loss, moderate exercise-induced muscle damage and stimulate protein synthesis in skeletal muscles.
