We examined five measures of ANS function, including three global measures [heart rate (HR) and systolic and diastolic blood pressure (SBP and DBP)-RSB-, one measure of parasympathetic nervous system (PNS) function [respiratory sinus arrhythmia (RSA)-RSB-, and one measure of SNS function [preejection period (PEP)-RSB-, as well as two markers of HPA axis function [cortisol and dehydroepiandrosterone - sulfate (DHEA - S)-RSB-.
