After a short historical account, and a discussion of Hill and Meyerhof's theory of the
energetics of muscular exercise, we analyse steady-state rest and exercise as the condition …

Homeostatic regulation plays a fundamental role in maintenance of multicellular life. At
different scales and in different biological systems, this principle allows a better …

Heart rate variability (HRV) is a cardiac autonomic marker with predictive value in cardiac
patients. Ultra-short HRV (usHRV) can be measured at scale using standard and wearable …

Purpose We hypothesised that during a rest-to-exercise transient in hypoxia (H), compared
to normoxia (N),(i) the initial baroreflex sensitivity (BRS) decrease would be slower and (ii) …

Past research links depression and blunted cardiac vagal reactivity to chronic stress. Yet, to
our knowledge no experiment investigates heart rate (variability) responses to a repeated …

People who are incarcerated are at heightened risk of overdose upon community reentry.
Virtual reality (VR) may provide an innovative tool for overdose prevention intervention in …

Purpose We tested the vagal withdrawal concept for heart rate (HR) and cardiac output (CO)
kinetics upon moderate exercise onset, by analysing the effects of vagal blockade on …

Purpose We analysed the characteristics of arterial baroreflexes during the first phase of
apnoea (φ1). Methods 12 divers performed rest and exercise (30 W) apnoeas (air and …

We hypothesised that vagal withdrawal and increased venous return interact in determining
the rapid cardiac output (CO) response (phase I) at exercise onset. We used lower body …

Abstract Neuropeptide Ys (NPYs) contribute to sympathetic‐adreno stimulation: NPY1‐36
potentiates the effects of catecholamines (CATs), whereas NPY3‐36 inhibits CAT release …
