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

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 …

The present study examined the autonomic cardiac modulation of veteran athletes by the
use of traditional and modern methods of heart rate variability (HRV) analysis. Twenty-nine …

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 …

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 …

Objectives The purpose of this study was to determine whether the type of training in a
young population differentiates heart rate variability parameters between athlete groups and …

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

Heart rate variability estimates cardiac autonomic modulation, but the relationship between
habitual physical activity and heart rate variability remains unclear. The aims of this study …

Heart rate variability reflects fluctuations in the changes in consecutive heartbeats, providing
insight into cardiac autonomic function and overall physiological state. Endurance athletes …

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 …
