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 ...

Applying lessons from limb muscle disuse and ageing to better understand ventilator‐induced diaphragm dysfunction

Experimental Physiology, EarlyView.
Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Performance, cardioventilatory and perceptual responses to perceived opponent ability during head‐to‐head cycling competition

Experimental Physiology, EarlyView.
Abstract We aimed to investigate whether cycling competition influences performance and pacing compared to an individual time trial. The second aim was to determine whether performance is further influenced by deceptive or accurate augmented feedback, delivered as an opponent riding at 2% higher power outputs than a previous competitive time trial ...
