Blood cytokine and salivary stress hormone levels in the subjects pre- and post-intense endurance exercise on the initial (A, C) and final (B, D) days of the training camp. Open and closed bars show the P and CT groups, respectively. Graphs A and B show mean levels of blood IL-6 and graphs C and D show mean levels of salivary cortisol for pre- and post-intense endurance exercise. Values are means ± SEM. * and *** Indicate significant difference (p < 0.05 and p < 0.001, respectively).
