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) …

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) provides important information about cardiac autonomic
modulation. Since it is a noninvasive and inexpensive method, HRV has been used to …

Purpose To investigate relationships between heart rate variability (HRV) and peripheral
and central performance measures, 17 cross-country (XC) skiers and seven canoeists were …

BACKGROUND: The aim of this study was to investigate the effects of exercise training on
autonomic regulation of heart rate under daily life conditions. METHODS: Twenty-six healthy …

The purpose of this study was to investigate the effect of twelve weeks of aerobic training
and eight weeks of training cessation on Heart Rate Variability (HRV). Ten healthy young …

The purpose of this study was to assess the effect of three different body positions on HRV
measures following short-term submaximal exercise. Thirty young healthy males performed …

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 …

Objective: The aim was to examine the cardiac autonomic responses to orthostatic stress
and recovery from steady state exercise in endurance trained athletes and sedentary …

Alterations in the heart rate recovery and heart rate variability have been associated with
greater risk of mortality and early prognosis of cardiac diseases. Thus, strategies for …
