On‐feet isometric bracing maintains cerebral arterial blood velocity during lower body negative pressure via preload augmentation

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1756-1765, 1 April 2026.
Abstract Orthostatic stress reduces venous return and stroke volume (SV), risking cerebral hypoperfusion despite autonomic compensation. Although lower‐limb counterpressure manoeuvres improve cerebral perfusion in upright posture, their effects on cerebral blood velocity (CBV) during lower‐body negative pressure (LBNP) and the associated mechanisms are
