Anabolic response to essential amino acid plus whey protein composition is greater than whey protein alone in young healthy adults.

ABSTRACT:

Background

We have determined the acute response of protein kinetics to one or two servings (6.3 g and 12.6 g) of a proprietary composition containing free-form essential amino acids (EAA) (3.2 g EAA per serving) and whey protein (2.4 g per serving), as well as the response to consumption of a popular whey-based protein supplement (Gatorade Recover) (17 g; 12.6 g protein).

Methods

Whole-body rates of protein synthesis, breakdown and net balance (taken to be the anabolic response) were determined using primed-constant infusions of ²H₅-phenylalnine and ²H₂-tyrosine. Muscle protein fractional synthetic rate (FSR) was also determined with the ²H₅-phenylalanine tracer.

Results

Plasma EAA levels increased fol
