The present meta-analysis aimed to quantify current evidence on sex differences in the
autonomic control of the heart, indexed by measures of heart rate variability (HRV) in healthy …

It has been demonstrated that heart rate variability (HRV) is predictive of all-cause and
cardiovascular mortality using clinical ECG recordings. This is true for rest, exercise and …

Background Autonomic regulation of heart rate (HR) as an indicator of the body's ability to
adapt to an exercise stimulus has been evaluated in many studies through HR variability …

The cardiac benefits of exercise have been recognized for centuries. Studies have
undisputedly shown that regular exercise is beneficial for the cardiovascular system in …

The development of performance in competition is achieved through a training process that
is designed to induce automation of motor skills and enhance structural and metabolic …

Heart rate variability (HRV) is a noninvasive, practical and reproducible measure of
autonomic nervous system function. A heart rate that is variable and responsive to demands …

Endurance training decreases resting and submaximal heart rate, while maximum heart rate
may decrease slightly or remain unchanged after training. The effect of endurance training …

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 …

Introduction: Heart rate variability (HRV), the beat-to-beat variation of adjacent heartbeats, is
an indicator of the function of the autonomic nervous system (ANS). Increased HRV reflects …

OBJECTIVE: The study aimed to investigate the effect of age and sex on the heart rate
variability (HRV) analysis and to explore the normal range of HRV in different age and sex …
