Branched Amino Acids,LEUCINE, ISOLEUCINE and VALINEare neutral amino acids with a branching at their linear chain. They are part of the family of essential amino acids and therefore cannot be manufactured by the body.
BCAA AND ANABOLISM
BCAAs are directly metabolised in muscle tissue and exercise increases their uptake and utilisation in activated muscle. They have the capacity (particularly leucine) to stimulate protein synthesis, which gives them an anabolic (muscle building) effect.
Researchers at the University of Rome have observed a significant improvement in lean mass and strength following a supplementation of 14 grams per day for 30 days of BCAAs (Leucine 50%; Isoleucine 25%; Valine 25%). At the same time, as demonstrated by the Yale University School of Medicine in New Haven, Connecticut, they actively combat proteolysis (muscle breakdown or catabolism).
A Swedish study also showed a clear reduction in proteolysis in marathon runners and other endurance athletes thanks to the intake of BCAAs.
BCAA AND FAT REDUCTION
BCAAs are an important source of energy and can promote fat loss when caloric intake is reduced, particularly at the visceral level (intra-abdominal fat).
In weight category sports and particularly in bodybuilding, this information is particularly interesting. . . losing fat weight while providing lean mass (muscle) protection and energy support. . . that's not so bad! In addition it would seem that a regular intake of BCAAs can lower the threshold of fatigue.
COACTIVE ELEMENTS OF BCAA
- LEUCINE: Anabolic - anti-stress - ketogenic - glycogenic
- ISOLEUCINE: Anabolism - anti-stress - cytogenic
- VALINE: Anabolism - anti-stress - glycogenic
- Metabolized by the lipid pathway
- Metabolized by the carbohydrate pathway
