Cardiovascular deconditioning and impact of artificial gravity during 60-day head-down bed rest—Insights from 4D flow cardiac MRI [PDF]
Frontiers in Physiology, 2022 Microgravity has deleterious effects on the cardiovascular system. We evaluated some parameters of blood flow and vascular stiffness during 60 days of simulated microgravity in head-down tilt (HDT) bed rest.

Thirty minutes of daily artificial gravity does not mitigate head down tilt induced brain activity changes during cognitive task performance [PDF]
Frontiers in NeurologyIntroductionStudies have shown that microgravity results in high dual task costs when crewmembers perform cognitive-motor dual tasking. Head-down tilt bedrest (HDBR) has been widely used as a spaceflight analog environment, recreating some of the ...

Development of and adherence to artificial gravity and resistive vibration exercises during 60 days of hypoxic 6° head‐down tilt bed rest: BRAVE study [PDF]
Experimental PhysiologyArtificial gravity (AG) combined with resistive vibration exercise has been proposed as a multi‐system countermeasure for long‐duration spaceflight; however, its operational feasibility during prolonged unloading remains insufficiently characterised ...

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 ...

Optic disc edema and chorioretinal folds develop during strict 6° head‐down tilt bed rest with or without artificial gravity [PDF]
Physiological Reports, 2021 Spaceflight associated neuro‐ocular syndrome (SANS) is hypothesized to develop as a consequence of the chronic headward fluid shift that occurs in sustained weightlessness. We exposed healthy subjects (n = 24) to strict 6° head‐down tilt bed rest (HDTBR),

Comparison of Autonomic Control of Blood Pressure During Standing and Artificial Gravity Induced via Short-Arm Human Centrifuge [PDF]
Frontiers in Physiology, 2018 Autonomic control of blood pressure is essential toward maintenance of cerebral perfusion during standing, failure of which could lead to fainting. Long-term exposure to microgravity deteriorates autonomic control of blood pressure.
