Ventilatory response to head‐down‐tilt in healthy human subjects [PDF]
Experimental PhysiologyPostural fluid shifts may directly affect respiratory control via a complex interaction of baro‐ and chemo‐reflexes, and cerebral blood flow. Few data exist concerning the steady state ventilatory responses during head‐down tilt.

Sleep Is Compromised in −12° Head Down Tilt Position [PDF]
Frontiers in Physiology, 2019 Recent studies are elucidating the interrelation between sleep, cranial perfusion, and cerebrospinal fluid (CSF) circulation. Head down tilt (HDT) as a simulation of microgravity reduces cranial perfusion.

Impact of daily artificial gravity on autonomic cardiovascular control following 60-day head-down tilt bed rest [PDF]
Frontiers in Cardiovascular Medicine, 2023 Impaired cardiovascular autonomic control following space flight or immobilization may limit the ability to cope with additional hemodynamic stimuli. Head-down tilt bedrest is an established terrestrial analog for space flight and offers the opportunity ...

Effects of intermittent seating upright, lower body negative pressure, and exercise on functional tasks performance after head-down tilt bed rest [PDF]
Frontiers in PhysiologyIntroductionBed rest can be used as a ground-based analog of the body unloading associated with spaceflight. In this study, we determined how strict head-down tilt bed rest affects subjects’ performance of functional tests (sit-to-stand, tandem walk ...

Effects of Head-down Tilt on Nerve Conduction in Rhesus Monkeys
Chinese Medical Journal, 2017 Background: Few studies have focused on peripheral nerve conduction during exposure to microgravity. The −6° head-down tilt (HDT) comprises an experimental model used to simulate the space flight environment.
