Summary

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.
