Objective Cardiovascular autonomic function, represented by heart rate variability (HRV) is a simple, non-invasive measure used to determine alteration of sympathetic and parasympathetic control. The aim of the present study was firstly to evaluate the effect of age and gender on HRV measures, and secondly to determine the relationship between measures of HRV and functional capacity in healthy individuals Methods This was a retrospective, single centre, cross-sectional, observational study. Data were collected between January 2018 and July 2019. Sixty-eight healthy participants (age range: 19-78 years) were stratified according to age into the younger age group (55 years of age, N = 25, males, N = 14; females, N = 11). Frequency domain HRV measures (i.e. absolute and normalised low frequency power (LF), high frequency power HF and their ration i.e. LF/HF ratio) were derived from RR interval and recorded at rest (supine position) for 30 minutes. Simultaneous non-invasive gas-exchange and central haemodynamic measurements (bioimpedance) were collected at rest and during maximal graded cardiopulmonary exercise stress test using semi-recumbent cycle ergometer. Results The mean age of the younger group was 26 ± 6 years and older 64 ± 6 years. Cardiorespiratory fitness (i.e. peak oxygen consumption) was significantly reduced in older compared to younger age group (1.60 ± 0.57 vs. 2.38 ± 0.74 L/min, p Conclusions High frequency power of the heart rate variability declines with age more in men but not women. Gender difference in high frequency power is apparent in older but not younger age, with older women showing nearly one third higher HF than older men. Measures of heart rate variability do not predict cardiorespiratory fitness
