Results of biochemistry assays for salivary biomarkers of stress: cortisol (a), chromogranin A (b) and alpha amylase (c). Saliva samples (Sal) were analyzed considering samples collected during morning and afternoon experimental sessions, separately (13 and 16 subjects, respectively). Data are shown as means ± SEM. Statistical significance was set for p < 0.05 (**p < 0.01; *p < 0.05, one-way ANOVA followed by Bonferroni Multiple Comparison Test).
