Myofibrillar protein fractional synthetic rates (FSR) calculated using the plasma L-[ring-²H₅]phenylalanine precursor pool for a postabsorptive (fasted) and postprandial (fed) period (a) and delta FSR change from postabsorptive to postprandial state (b) for both MYC and PCM conditions in rested and exercised (unilateral leg press and leg extension) muscle in health young resistance-trained males. Postprandial state represents a 4 h period following drink consumption (70 g of mycoprotein containing 31·5 g protein and 2·5 g leucine (MYC; n 12) or 38·2 g of protein concentrated from mycoprotein containing 28·0 g protein and 2·5 g leucine (PCM; n 10)), and execution of a bout of unilateral resistance leg exercise. Data were analysed using a three-way (protein ingestion × group × exercise) ANOVA. Delta FSR data were analysed using a two-way (group × exercise) ANOVA. †Significant difference between fasting and fed conditions (main effect of protein ingestion; P < 0·0001). #A significant difference between rested and exercised tissue in fed conditions (exercise × feeding interaction; P < 0·01). Values are mean ± sem.
