Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

Cardiopulmonary function in special operations forces compared to conventional infantry soldiers
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 ...

Abstract Consumption of a high‐sugar mixed meal (HSMM) increases both glucose and insulin and elicits mixed vascular effects, with reduced microvascular blood flow but increased conduit artery diameter and blood flow. In this study, we sought to examine: (1) whether an HSMM elicits vascular segment‐specific effects within cerebrovasculature; and (2 ...

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