BRANCH CHAIN AMINO ACIDS…

Its All In the Timing!
Amino acids are the building blocks of all protein and are therefore essential for the synthesis of structural proteins, enzymes, some hormones and neurotransmitters as well as being essential in many metabolic pathways that affect exercise metabolism. Following water, protein is the most plentiful substance in the body and roughly one third of horse protein is found in muscle. While all protein is made up of amino acids, all proteins are not the same however are manufactured using different combinations of the same 22 amino acids.
The five branch chain amino acids (BCAA's) – leucine, isoleucine, valine, glutamine and carnitine are all classed as ‘essential' amino acids and are most plentiful in muscle tissue.
As muscles burn up available BCAA's during exertion, they begin to break down muscle tissue to provide essential fuel to facilitate further activity. In the case of insufficient BCAA provision, muscle cell damage occurs resulting in reduced ability of muscles to contract and relax during extreme exertion, muscle fatigue, lactic acidosis, loss of performance and delayed recovery as muscle tissue completes the repair process. Intense exercise results in
large amounts of BCAA's being depleted, as exertion acts to stimulate the breakdown of liver proteins and hepatic secretion of BCAA's in addition to their uptake into muscle cells (Ahlborg et al, 1974; Felig et al, 1971). Interestingly, when BCAA's are supplemented, muscle appears to utilize them preferentially to degrading pre-existing myofibrillar proteins (Nissen et al, 1981).
Specifically, supplemented leucine has been observed to directly inhibit muscle protein degradation.
The following beneficial effects have been reported following pre-exercise supplementation of key amino acids (BCAA's);
