Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Acute cardiovascular changes following heat exposure during simulated shipboard firefighting

Experimental Physiology, EarlyView.
Abstract Like structural firefighting, shipboard firefighting requires extreme exertion. However, shipboard firefighting may be a unique cardiovascular stress as most sailors lack extensive firefighting experience and may complete significant work before reaching the fire scene.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Therapeutic intervention with sinomenine and irisin to preserve cardiac function after ischaemia–reperfusion injury

Experimental Physiology, EarlyView.
Abstract Despite advancements in reperfusion therapy, myocardial ischaemia–reperfusion (IR) injury remains a major clinical challenge. This study investigated whether a novel dual‐target pre‐conditioning strategy using sinomenine and irisin could enhance myocardial resistance against IR injury. Ninety male Sprague–Dawley rats were utilized.

Haemodynamic responses to head‐up tilt versus lower‐body negative pressure in type 1 diabetes

Experimental Physiology, EarlyView.
Abstract Head‐up tilt (HUT) and lower‐body negative pressure (LBNP) both reduce central blood volume but differ in heart orientation and regional fluid shifts. Whether they evoke comparable cardiovascular regulation when matched for preload remains uncertain.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...
