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.

Cardiopulmonary function in special operations forces compared to conventional infantry soldiers

Experimental Physiology, EarlyView.
Abstract Fitness is essential to military personnel in general, especially in the special operations forces (SOF), where the demanding tasks require a high level of physical fitness and mental robustness. However, little research has been done on SOF to characterise the putative underlying cardiopulmonary adaptations that distinguish them from ...

Effects of high‐intensity interval training on cardiac function in hypertensive and normotensive men: Effects of antihypertensive treatment

Experimental Physiology, EarlyView.
Abstract Exercise training is recommended for individuals with hypertension because it has been shown to lower blood pressure and reverse left ventricular concentric remodelling and mass. However, it is unclear how hypertensive individuals respond in comparison to normotensive individuals and to what extent medical treatment affects the outcome of ...

Interpreting peripheral oxygen saturation variability in critical illness: A directional framework adjusted for hypoxia severity

Experimental Physiology, EarlyView.
Abstract Peripheral oxygen saturation (SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$) exhibits a complex pattern of fluctuations during hypoxia, which can be quantified using entropy measures. SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$ entropy analysis provides insights into dynamic physiological regulation by non‐invasively reflecting the body's capacity to ...

Estimated exercise‐induced maximal myocardial blood flow in untrained and endurance‐trained men

Experimental Physiology, EarlyView.
Abstract The heart critically depends on a continuous supply of oxygen, provided by myocardial blood flow (MBF), but reliable quantification of MBF during maximal exercise is not feasible in humans. We measured MBF at rest and during similar absolute (150 W) and relative (70% of V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_{\mathrm{2}}}{\mathrm{max ...

Ghrelin protects against cell death in myocardial ischaemia: Emerging role of microRNA

Experimental Physiology, EarlyView.
Abstract Acute myocardial infarction (MI) accelerates cardiomyocyte apoptosis, which underpins ventricular remodelling and dysfunction. The hormone ghrelin mitigates this remodelling, but the mechanisms remain unclear. Specific microRNAs (miRs) are key modulators and reliable biomarkers of early‐stage apoptosis.
