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 …

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 …

The role of the autonomic nervous system. The mechanisms by which physical training
exerts its beneficial effects on mortality and cardiovascular disease are surprisingly ill …

Objectives. We tested the effect of aerobic exercise on autonomic regulation of the heart in
healthy young adults. Methods. Healthy, sedentary young adults (n= 149; age= 30.4±7.53 …

This study investigated changes in heart rate variability (HRV) in elite Nordic-skiers to
characterize different types of “fatigue” in 27 men and 30 women surveyed from 2004 to …

The present study aimed to evaluate the effects of a highly-demanding match and a lowly-
demanding match on pre-competitive heart rate variability (HRV) and anxiety in semi …

OBJECTIVE: Evidence of elevated basal heart rate (HR) in posttraumatic stress disorder
(PTSD) has been interpreted in terms of elevated sympathetic cardiac activity, as have …

Background Heart rate variability (HRV) has been rarely applied in elite athletes prior to
competition. The aim of this study was to examine the changes in HRV in elite female …

Caloric restriction (CR) increases maximum lifespan but the mechanisms are unclear.
Dominance of the sympathetic nervous system (SNS) over the parasympathetic nervous …
