Heart rate variability (HRV) analyses can provide a non-invasive evaluation of cardiac
autonomic activity. How autonomic control normally develops in childhood and how this is …

Background High intensity interval training (HIIT) has been used as a cardiovascular
exercise strategy to promote greater adherence in cardiovascular rehabilitation. However …

Abstract Background and Objectives: In spite of the existence of a multitude of techniques
that allow the estimation of stress from physiological indexes, its fine-grained assessment is …

Objective To assess the distribution of autonomic nervous system (ANS) dysfunction in
overweight and obese children. Methods Parasympathetic and sympathetic ANS function …

Background: High resting heart rate is considered an important factor for increasing mortality
chance in adults. However, it remains unclear whether the observed associations would …

Most experimental studies on animal stress physiology have focused on acute stress, while
chronic stress, which is also encountered in intensive dairy cattle farming–eg in case of …

OBJECTIVES: There are no data in the literature with regard to the acute effects of different
styles of music on the geometric indices of heart rate variability. In this study, we evaluated …

Physical activity is a protective factor for autonomic dysfunction. However, whether this
occurs in adolescents with abdominal obesity is still unclear. Thus, the aim of this study was …

Heart rate and blood pressure are the most important vital signs in diagnosing disease. Both
heart rate and blood pressure are characterized by a high degree of short term variability …

Background It was already evidenced decreased heart rate variability (HRV) in chronic
obstructive pulmonary disease (COPD) patients at rest. Objective In order to insert new …
