BCAA is short for Branched Chain Amino Acid. The BCAAs are leucine, isoleucine and valine. These are 3 of the 9 essential amino acids in the human body. Essential amino acids cannot be produced by the body. You must get them through your diet. These 3 unique amino acids make up over 40% of your daily required essential amino acid intake.
BCAAs are unique in many ways but one extraordinary aspect of these 3 amino acids is that they bypass liver metabolism and are transported and metabolized directly in muscle. They are the primary building blocks of muscle tissue proteins. They also are carbon and nitrogen precursors for the synthesis of alanine, glutamate, and glutamine.
BCAAs are shown to have anabolic effects in human muscle. They are required for muscle tissue maintenance and preserve glycogen stores in muscle tissue. The BCAAs are the primary amino acids responsible for protein synthesis. In fact, the tissue building effects from protein are primarily due to BCAAs.
The anabolic activity of BCAAs are from multiple pathways. Studies show that the BCAAs and in particular leucine stimulates muscle protein synthesis by acting as both a signal and a substrate. One way BCAAs do this is through signaling mTOR activity in human muscle tissue. mTOR is the primary regulator of muscle growth through amino acid sensoring. BCAAs appear to signal mTOR to activate protein synthesis after exercise.
BCAAs effect on increasing lean muscle tissue stems from its anabolic activity as well as its anti-catabolic activity. Studies show taking BCAAs before training is effective at suppressing muscle tissue breakdown after training.
These study results suggest that BCAAs have a protein-sparing effect during the recovery after exercise, and that protein synthesis is stimulated and/or protein degradation is decreased. There are also indications, though difficult to measure, that these same effects happen during exercise as well.
