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 ...

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

Experimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Left ventricular morphological and functional predictors of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$: A 3‐year observational study

Experimental Physiology, EarlyView.
Abstract The aim of the study was to identify central determinants of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$ using a 3‐year longitudinal evaluation of left ventricular (LV) morphological and functional (global, tissue‐Doppler and strain) outcome measures obtained at rest and during both submaximal and maximal exercise in a group of highly

EuroSCORE II: Current limitations and physiological gaps in risk stratification

Experimental Physiology, EarlyView.
Abstract Risk stratification remains critical in cardiac surgery, enabling clinicians to predict adverse outcomes and guide perioperative management. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, introduced in 2011, incorporates 18 key variables to provide an evidence‐based approach to risk assessment.

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 ...
