The effect of one period HIIT training and BCAA supplementation on indicators muscle damage in non-athlete men

Matinhomaei Hasan, Peeri Maghsoud, Mahdi Fatemeh

It is important to realize that each amino acid plays a different metabolic or biochemical role in the human body and that deficiency of one amino acid may also affect the functioning. It is worth noting here that the requirements for specific amino acids are directly altered when the body is under stress. In the other words, physical disorders and plasma amino acid levels bear a direct relationship to each other. One of these amino acids that isused by the athletes is BCAA. The BCAAs ,include leucine, isoleucine, and valine represent 3 of the 20 amino acids that are used in the formation of proteins. BCAA supplementation may help prevent muscle damage during aerobic exercisedue to leucine's potential regulatory rolein protein synthesis, altered hormone levels, and increasing the amino acid content in free pools which may prevent the need for protein degradation(1). The aim of this research was study of effects of BCAA supplementation and HIIT training on the muscle injury factors ( creatine kinase (CK), lactate dehydrogenase (LDH) and aldolase(ALD).
