Sažetak
Stress is a condition which disturbs inner (psychophysiological) balance of the organism activating the hypothalamic - pituitary - adrenal axis. Salivary cortisol is used as an indicator of free cortisol, correlates well with serum free value and reflects biologically active fraction. At the same time, stressful situation stimulates the sympathetic neural system which causes a change in the secretion of salivary alpha amylase. The aim of the study was to investigate correlation of salivary cortisol and alpha amylase (sAA) with physical activity induced stress and psychological indicators in student population. The study included 54 healthy volunteers, 27 (15 males, 12 females) physically active volunteers from Faculty of Kinesiology (FK) and 27 (14 males, 13 females) physically less active volunteers from other faculties (OF), aged 19 - 26 years. All participants were subject to psychological testing (approved Croatian version of COPE and WHOQOL-BREF). Saliva samples were taken in Salivetta system (Sarsted, Germany) between 10 -12 am. Both, salivary cortisol and alpha amylase were determined by ELISA method (Euroimmun, Luebeck, Germany). The results have shown statistically significant higher sAA concentration in males in FK subgroup (P=0.008) and in all males (P=0.033). Concentrations of salivary cortisol did not differ between subgroups (P=0.426) or gender (females, P=0.241 ; males P=0.930). Psychological testing showed difference between studied subgroups only in the focused problem-coping (FK, P=0.023). The results did not show correlation between sAA and cortisol and the level of the physical activity (r=-0.225, P=0.102). Statistically significant, but weak negative correlation between sAA and cortisol was found in OS subgroup (r=-0.410, P=0.034). No correlation was found between psychological testing results and investigated salivary markers. According to our results, there is no correlation between concentrations of sAA and salivary cortisol with the level of physical activity or with the psychological indicators in students.
