FIGURE 5.

Overnight intramuscular connective tissue protein synthetic rates (FSR in %·h⁻¹) as calculated using L-[ring-²H₅]-phenylalanine or L-[1-¹³C]-leucine as tracer. The data are presented as box and whisker plots with the median (line), mean (cross), interquartile range (box), and minimum and maximum values (tails). Treatments without a common letter differ, P < 0.05. Data were analyzed with a one-way (between-subject factor: treatment) ANOVA. FSR based on L-[ring-²H₅]-phenylalanine; main treatment effect, P = 0.002. EX vs PRO and EX + PRO vs PRO post hoc comparisons, P < 0.005. FSR based on L-[1-¹³C]-leucine: main treatment effect, P = 0.166. PRO, presleep protein ingestion without prior exercise; EX, placebo ingestion with prior exercise; EX + PRO, protein ingestion with prior exercise.
