FIGURE 2.
Overnight plasma total amino acid (A) and essential amino acid (B) concentrations (μmol·L−1). The dotted line represents the ingestion of the presleep protein. Values represent mean ± SD. Data were analyzed with a two-way repeated-measures (within-subject factor: time; between-subject factor: treatment) ANOVA. Total amino acids: time effect, P < 0.001; treatment effect, P < 0.001; time–treatment interaction, P < 0.001. Essential amino acids: time effect, P < 0.001; treatment effect, P < 0.001; time–treatment interaction, P < 0.001. TAA, total amino acids; EAA, essential amino acids; PRO, presleep protein ingestion without prior exercise; EX, placebo ingestion with prior exercise; EX + PRO, protein ingestion with prior exercise.
