The Effect of a Novel Plant-blend Protein Isolate on Post-exercise Myofibrillar Protein Synthesis When Compared to Whey Protein in Healthy Young Adults

Dietary protein ingestion is required to maximise the anabolic response during the recovery from resistance exercise. Whey protein is considered the optimal dietary strategy to maximise post-exercise muscle protein synthesis, but animal-protein production and consumption is associated with growing environmental and ethical concerns. Plant-based protein sources are considered of lesser anabolic quality than isonitrogenous boluses of animal-derived protein attributed to, at least in part, deficiencies in key essential amino acid. Blending different protein sources may overcome amino acid deficiencies and potentiate the post-exercise anabolic response. In the present study the investigators assessed the post-exercise muscle protein synthetic response following the ingestion of a novel plant-based protein isolate when compared with an isonitrogenous bolus of whey protein in healthy young, resistance trained women and men.
