Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Vascular, inflammatory and perceptual responses to hot water immersion: Impacts of water depth and temperature in young healthy adults

Experimental Physiology, EarlyView.
Abstract Repeated hot water immersion can improve cardiovascular health; however, the respective effects of distinct immersion protocols remain unclear. Twenty‐two healthy adults completed three 30‐min hot water immersion bouts of different water temperatures and immersion depths (40°C shoulder‐deep immersion, 40‐Shoulder; 42°C waist‐deep immersion, 42‐

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.

Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

Experimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

Sex‐related differences in the peripheral vascular response to hypoxia: Implications in health and relevance for obstructive sleep apnoea

Experimental Physiology, EarlyView.
Abstract The incidence and presentation of obstructive sleep apnoea, as well as hypertension and cardiovascular disease, have been reported to differ by sex. It is thus reasonable to propose mechanisms contributing to subsequent pathology differ by sex. This concept is supported from a pre‐pathological perspective, as sex differences have been observed

Lower limb blood flow responses during higher‐ and lower‐load bilateral leg press exercise

Experimental Physiology, EarlyView.
Abstract The local blood flow response to resistance exercise (RE) is complicated by local muscular contractions and large swings in perfusion pressure. The magnitude of these responses might vary according to exercise intensity, number of sets and number of repetitions, and as a result, the local shear environment during RE remains uncharacterized. We

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Leg‐fidgeting versus standing breaks during prolonged sitting: Impacts on blood pressure and heart rate in young women

Experimental Physiology, EarlyView.
Abstract The objective of this work was to examine whether leg‐fidgeting breaks during prolonged sitting could be a practical alternative to standing breaks in preventing blood pressure (BP) and heart rate (HR) impairments. Young women (n = 16; age = 21.9 ± 3.0 years; body mass index = 21.1 ± 4.9 kg/m2) completed three 3‐h prolonged sitting conditions ...
