Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

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.

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.
