Heart rate variability (HRV) is a known risk factor for mortality in both healthy and patient
populations. There are currently no normative data for short‐term measures of HRV. A …

Over the last 20 years, heart rate monitors (HRMs) have become a widely used training aid
for a variety of sports. The development of new HRMs has also evolved rapidly during the …

This review examines the influence on heart rate variability (HRV) indices in athletes from
training status, different types of exercise training, sex and ageing, presented from both …

Purpose The aim of the present study was to determine the effects of exercise training on
heart rate and measures of heart rate variability associated with vagal cardiac modulation …

Background Regular exercise promotes functional and structural changes in the central and
peripheral mechanisms of the cardiovascular system. Heart rate variability (HRV) …

Heart rate variability (HRV) is a non‐invasive indicator of cardiac autonomic modulation at
rest. During rhythmic exercise, global HRV decreases as a function of exercise intensity …

Purpose The aims of this study were 1) to assess day-to-day stability of resting heart rate
variability (HRV) in healthy adults; 2) to determine whether the reliability of these measures …

Heart rate variability (HRV), a non-invasive index of autonomic controls of the heart, has
extensively been employed in various fields of study. The application range of this index …

The purpose of the present study was to determine if autonomic heart rate modulation,
indicated by heart rate variability (HRV), differs during supine rest and head-up tilt (HUT) …

To investigate whether the manipulation of brain excitability by transcranial direct current
stimulation (tDCS) modulates the heart rate variability (HRV), the effect of tDCS applied at …
