Numerous scientific studies suggest the positive effects that BCAAs can have on protein synthesis (muscle growth). BCAAs stimulate protein synthesis through multiple pathways. One of the major mechanisms by which BCAAs stimulate protein synthesis is through leucine’s activity in the mammalian target of rapamycin (mTOR) pathway.* Several human studies suggest increased protein synthesis and decreased protein breakdown when BCAA’s are supplemented before, during, and after exercise.
BCAAs can have a glycogen sparing effect and can help maintain muscle and liver glycogen stores during exercise. By sparing glycogen, BCAAs can increase fuel supply to working muscle during exercise, resulting in greater performance!
An additional mechanism for exercise performance support from BCAAs is inhibition of central nervous system (CNS) fatigue. Exercise causes an increase in serotonin levels, and this can cause CNS fatigue. Since BCAA’s share the same transporter system with tryptophan (the serotonin precursor amino acid), BCAA supplementation causes competitive inhibition of tryptophan transport to the brain, which in turn reduces serotonin levels. Exercise increases the tryptophan/BCAA ratio in the bloodstream, and a BCAA supplement may prevent or reverse this. This means that BCAA’s could increase exercise performance by decreasing build up of serotonin in the brain. Multiple studies suggest that BCAA supplements successfully change the BCAA/tryptophan plasma ratio, especially during more prolonged exercise.
