How BCAAs Grow Muscle
Amino acids are strung together by the body into polypeptide chains which serve as the basis of all proteins in the body- from muscle tissue, to skin, to enzymes that catalyze vital reactions. The amount of free amino acids you have influence the rate of protein synthesis in your body- how fast you make the proteins and how much you make. Revved up protein synthesis is how your cells grow, including muscle tissue.
BCAAs are the 3 amino acids (Leucine, Isoleucine,Valine) with the unique property of having a branched non-polar side chain, making these amino acids hydrophobic and playing a major role in how these amino acids are used. BCAAs, and specifically leucine, have shown the ability to increase protein synthesis levels by stimulating the mTOR (mechanistic target of rapamycin) pathway. BCAAs have the ability to trigger the phosphorylation of mTOR which communicates to the cell to rev up synthesis-and this is dependent on the concentration of BCAAs in your cell. BCAA supplementation of 7g has been show to increase protein synthesis 22%.
“All studies included in the current analysis were:peer-reviewed publications; available in English; utilized a random control design that compared a BCAA group to a placebo control group following exercise; and assessed soreness of muscle tissue during recovery.Delayed-Onset-Muscle-Soreness was assessed in 61 participants following ingestion of a BCAA supplement over the course of these interventions. The cumulative results of 37 effects gathered from 8 studies published between 2007 and 2017 indicated that BCAA supplementation reduced DOMS following exercise training (ES = 0.7286, 95% CI: 0.5017 to 0.9555, p < 0.001). A large decrease in DOMS occurs following BCAA supplementation after exercise compared to a placebo supplement.”
Intra-Fuel have been shown to promote muscular endurance, decrease fatigue, and improve muscle recovery by playing a key role in stimulating protein synthesis. They are part of an optimal and essential post workout routine for any active individual looking to recover faster from training with no calories or sugar!
