From: Salivary diagnostic markers in males and females during rest and exercise
Mean data for salivary markers of (a). mucosal immunity, SIgA (mg·L−1); (b) the sympathetic stress response, α-amylase activity (U·mL−1) and c. the adrenal stress response, cortisol (μg·L−1), and associated errors between rest and exercise for males and females. A significant difference between rest and exercise is indicated with an asterisk (**, P < 0.001; *, P < 0.05) and between males and females with letters (b, P < 0.001; b, P < 0.05)
