Correlation Between Salivary Biochemical Stress Indicators and Psychological Indicators.

Correlation Between Salivary Biochemical Stress Indicators and Psychological Indicators. Acta Clin Croat. 2018 Jun;57(2):316-326 Authors: Crnković D, Peco M, Gelo J Abstract Saliva is a complex body fluid that has various functions in the oral cavity. Central nervous system has the most important role in regulating salivation. Saliva as a sample is suitable for simplicity of sampling and because it contains analytes in the free active form. Stress is a condition in which the internal (psychophysical) balance of the body is disturbed. It activates the hypothalamic-pituitary axis, so salivary cortisol is a free cortisol indicator that correlates well with its serum value and reflects the free fraction that is biologically active. At the same time, stress conditions stimulate the sympathetic neuronal system causing change in the secretion of salivary α-amylase from salivary glands. The hypothesis of this study was that students with daily intensive physical activity are ex-posed to chronic stress compared to other students who have minimal physical activity. The study in-cluded 54 healthy volunteers, students of the University of Zagreb, divided into two groups. One volunteer group consisted of physically active volunteers (n=27) from the Faculty of Kinesiology (FK), and the other group consisted of physically inactive volunteers (n=27) from other faculties (OF). The subjects were first administered a psychological test that consisted...
