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 …

Sleep and exercise influence each other through complex, bilateral interactions that involve
multiple physiological and psychological pathways. Physical activity is usually considered …

Measures of resting, exercise, and recovery heart rate are receiving increasing interest for
monitoring fatigue, fitness and endurance performance responses, which has direct …

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 …

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 …

The measurement of heart rate variability (HRV) is often considered a convenient non-
invasive assessment tool for monitoring individual adaptation to training. Decreases and …

Purpose: We analyzed heart rate variability (HRV) to detect alterations in autonomic function
that may be associated with functional overreaching (F-OR) in endurance athletes. Methods …

The aims of the present study were to (1) assess relationships between running
performance and parasympathetic function both at rest and following exercise, and (2) …
