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.

No evidence of higher peak heat tolerance in the afternoon or with opportunity for thermal behaviour during low‐intensity work in uncompensable heat

Experimental Physiology, EarlyView.
Abstract Heat tolerance is known to be limited by high brain temperature, but most findings pertain to strenuous exercise following artificially altered baseline temperature or with limited opportunity for behaviour. Therefore, we investigated the hypotheses that thermal perceptions, hyperventilation and cerebrovascular responses would be exacerbated ...

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

The theoretical basis of reservoir pressure in arteries

Experimental Physiology, EarlyView.
Abstract The separation of measured arterial pressure into a reservoir pressure and an excess pressure was introduced over 20 years ago as a heuristic hypothesis. Since then it has gained some traction through epidemiological studies that show that various measures of reservoir and excess pressure are independent risk factors for cardiovascular disease.

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 ...

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Effect of foot immersion and neck cooling on renal, intestinal, immune and inflammatory markers in older adults exposed to extreme heat

Experimental Physiology, EarlyView.
Abstract Older adults with reduced thermoregulatory capabilities are increasingly at risk of heat‐related pathophysiological outcomes (e.g., acute kidney injury, heatstroke) due to increasingly frequent, prolonged and intense heatwaves. Foot immersion and neck cooling have been proposed as practical, non‐electrical cooling strategies for protecting ...
