Comparison of exercise training and repeated hot water immersion on vascular function in overweight older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Recent studies suggest that heat exposure may benefit cardiovascular health, but in overweight and obese older adults, the chronic effects of heat therapy on artery function are still uncertain. We aimed to compare the effects of 12 weeks (3×/week, 40 min) of aerobic exercise (EXE) to hot water immersion (HWI) and an inactive control group ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

A constitutive modelling framework for applications to in vivo longitudinal data: Evaluation in a 60‐day head‐down bed rest study on arterial function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We proposed a computational constitutive modelling framework that leverages longitudinal acquisitions of haemodynamic waveforms at multiple arterial locations to achieve a biomechanical characterisation of their (micro)structural remodelling processes.

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Mechanisms reducing parasympathetic activity in chronic hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...
