Psychophysiological research integrating heart rate variability (HRV) has increased during
the last two decades, particularly given the fact that HRV is able to index cardiac vagal tone …

Studies show that the autonomic nervous system (ANS) has an important impact on health in
general. In response to environmental demands, homeostatic processes are often …

Heart rate variability (HRV) is frequently applied in sport-specific settings. The rising use of
freely accessible applications for its recording requires validation processes to ensure …

Cardiac parasympathetic activity may be non-invasively investigated using heart rate
variability (HRV), although HRV is not widely accepted to reflect sympathetic activity …

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

The increase in competition demands in elite team sports over recent years has prompted
much attention from researchers and practitioners to the monitoring of adaptation and …

Autonomic nervous system activation can induce significant and heterogeneous changes of
atrial electrophysiology and induce atrial tachyarrhythmias, including atrial tachycardia and …

The aim of this paper is to set the stage for the vagal tank theory, showcasing a functional
resource account for self-regulation. The vagal tank theory, building on neurophysiological …

A conceptual framework has a central role in the scientific process. Its purpose is to
synthesize evidence, assist in understanding phenomena, inform future research and act as …

The response to an exercise intervention is often described in general terms, with the
assumption that the group average represents a typical response for most individuals. In …
