  1. F2: Repeated measures ANOVA model with two intervals during the early stage of the stress test (baseline and 0–10 min). F6: Model with six intervals during the stressful task (0–60 min). F3: Model with three intervals during recovery (65–95 min). p: Probabilities (degrees of freedom in parentheses) was adjusted for non-sphericity with Huyhn-Feldt's method. Significant interactions in bold.
