Blood amino
acid levels control muscle protein synthesis
For bodybuilders, one
of the most important revelations in exercise biochemistry for the last
50-years is the confirmation that blood amino acid concentrations
control muscle growth. A high protein intake maintains a high level of
essential amino acids circulating in the blood. This is the key to
stimulating muscle protein synthesis rates. When blood amino acid levels
drop, muscle protein synthesis rates diminish. Research show that this
powerful anabolic effect is not achieved with "normal" dietary protein
intakes. A high protein intake is essential for maximizing the anabolic
effect of resistance training.
The best way to
maintain high blood amino acid levels in the blood is to combine protein
sources that possess different absorption rates. The simplest way to do
this is to combine whole food proteins with meal replacement supplement
whey protein.
Each protein source
possess different absorption rates that govern the entry of amino acids
into the blood stream. Whole foods allow amino acids to "trickle" into
the blood stream. However, whole-food proteins are essential to the
muscle growth process as they help stabilize blood sugar levels to
ensure the protein in your supplements is directed towards muscle
protein synthesis and not energy production.
Therefore, always try
to combine your supplements with a high intake of whole-food protein
sources like tuna, beef, chicken and eggs. Try to consume a fast and
slow protein source at nearly every meal to maintain a high level of
growth promoting amino acids in the blood stream at all times.
