This study will be a randomised, double-blind trial where participants will be randomly assigned to consume either a i) vegan whey protein; ii) a whey protein; or iii) a non-protein carbohydrate control supplement for 3 days following strenuous eccentric knee extension exercise. For the duration of the study period, participants will orally consume deuterated water stable isotope tracer (D2O). This, together with repeated blood sampling and muscle biopsies will allow for the calculation of free-living myofibrillar protein synthesis rates under conditions of rest and over 24-, 48- and 72-hours post-exercise recovery.
