Leucine & Citrulline Build Muscle

Leucine & Citrulline Build Muscle Yesterday's post described how different resistance training protocols affect protein synthesis, the mechanism behind muscle size and strength gains. Today's research on the mass building qualities of leucine and citrulline was published in the journal Amino Acids.

Leucine is one of the Branched Chain Amino Acids (BCAAs) and citrulline is an amino acid typically associated with muscle pump promotion. Researchers supplemented the diets of lab rats with leucine and citrulline for a week. Not only did these supplemented rats end up with improved muscle mass, they were much more active than rats fed a typical diet.

True Strength Moment: When these results were analyzed further, it was discovered that leucine helped increase maximal isometric force in these rodents. Now the question becomes, if two amino acids are good, what kind of support for your fitness goals can you expect if you include the other 20 amino acids? Today's Performance Blog post at ABBperformance.com has the answer!
