Objective Heart rate variability (HRV) analysis has been used to evaluate patients with
various cardiovascular diseases. While the vast majority of HRV studies have focused on …

Abstract Background Spectral analysis of Heart Rate Variability (HRV) is a simple, non-
invasive technique that is widely used in sport to assess sympatho-vagal regulation of the …

Prolonged training leads to changes in autonomic cardiac balance. This sympathetic and
parasympathetic balance can now be studied using heart rate variability (HRV). Studies …

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 …

Autonomic cardiac function can be indirectly detected non-invasively by measuring the
variation in microtiming of heart beats by a method known as heart rate variability (HRV) …

(HRV) as a Tool for Diagnostic and Monitoring Performance in Sport and Physical Activities.
JEPonline 2013; 16 (3): 103-131. The dynamic autonomic responses during exercise can be …

Heart rate variability (HRV) is a relevant marker reflecting cardiac modulation by sympathetic
and vagal components of the autonomic nervous system (ANS). Although the clinical …

Background Aging is associated with decreased autonomic balance which could be
assessed by Heart Rate Variability (HRV). Exercise training improves autonomic balance …

The aim of this study was to evaluate the reproducibility of the heart rate variability threshold
(HRVT) by different HRV indexes and determination criteria. 68 untrained participants, 17 …

The purpose of this investigation was to examine the relationships between aerobic fitness,
volume of physical activity (PA), heart rate variability (HRV), and heart rate recovery (HRR) …
