Influence of prior alkalosis or acidosis on physiological responses during passive hyperthermia

Experimental Physiology, EarlyView.
Abstract This study manipulated the blood pH of participants to be mildly acidic or basic prior to passive hyperthermia to examine its effects on thermoregulatory and chemo‐regulatory responses, including ventilatory parameters, rectal temperature (Tre) and thermal perception. Twelve healthy males attended three experimental sessions in a double‐blind,

Intermittent hand and forearm immersion in 20°C water attenuates thermal, cardiovascular, and perceptual strain in older adults during heat stress

Experimental Physiology, EarlyView.
Abstract Adults >65 years of age experience deleterious health effects during extreme heat events at a greater rate than any other age cohort. The purpose of this study was to identify the effectiveness of acute intermittent hand and forearm (H+F) water immersion and/or chronic (7 week) folic acid supplementation on reducing thermal and cardiovascular ...

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.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Applying thermal therapy: Comparison of different commercially available heating devices to increase muscle temperature

Experimental Physiology, EarlyView.
Abstract Although various medical devices are available for the purpose of heat therapy, their effect on muscle temperature remains unclear. This study compared the effects of a water‐perfused suit (WPS), short‐wave diathermy (SWD) and hot‐water immersion (HWI) on muscle, core and skin temperatures, along with perceived thermal discomfort.

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.
