Amino acids are represented by branched or BCAA leucine, isoleucine & valine & make up 35% of the amino acids present in the muscle.
Unlike most other amino acids, BCAA bypasses hepatic metabolism & are directly involved in muscular work, which serve as nitrogen donors for the synthesis of other important amino acids such as glutamine & alanine. In doing so exert an action on anti-catabolic muscle.
- Greater stimulation of protein synthesis
- Increased muscle strength by the opposition of the way in of free tryptophan in the brain. The latter is an essential amino acid that in the last stages of physical activity, when BCAA are beginning to be used as an energy substrate, enters the brain, where it is converted in to serotonin, a brain neurotransmitter that gives the sensation of fatigue (this is a nice reason to take before a workout BCAA)
- Limiting the formation of ammonia (a substance poisonous to the tissues that form in the coursework of the exercise, which also prevents protein synthesis).
- More energy in the coursework of workouts. This is due to the fact that the oxidation of BCAA in the coursework of their form alanine, which is the most important precursor of gluconeogenesis (formation of new glucose & therefore energy) in the liver, maintaining stable blood sugar levels. Not to mention that the synthesis of glutamine is dependent on the BCAA.
- Like steroids, the BCAAs work best when the muscle is in a catabolic state, such as through a low-calorie diet, so the branching can help prevent muscle loss in the coursework of strict diets
- greater recovery
- Stronger immune system
