Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

open access: yesThe Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.

Vascular smooth muscle cell mechanotransduction: Pathways, phenotypes and emerging technologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Vascular smooth muscle cells are exposed to mechanical stimuli from the blood flow and the extracellular matrix. The cells sense the signals from cyclic stretch, shear stress, hydrostatic pressure and matrix stiffness through specialized mechanosensors, such as mechanosensitive ion channels or cell surface receptors including ...

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.

Heart failure‐induced reprogramming of salt‐evoked neurovascular coupling in the rat hypothalamus

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In sham rat, hypertonic saline induces activation of the AVP neurons, leading to dendritic AVP release and subsequent V1aR‐mediated PA vasoconstriction resulting in local tissue hypoxia in the SON. In heart failure rat, hypertonic saline similarly induces activation of the AVP neuron leading to dendritic AVP release.

The heart responds to pressure via the lung: Dive depth alters cardiac control in bottlenose dolphins

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dive depth independently modulated cardiac regulation in bottlenose dolphins during controlled voluntary dives. Dolphins performed dives to 0.5, 5 and 10 m with standardized dive durations, allowing the effects of depth on cardiovascular responses to be evaluated.
