Abstract: Microgravity alters vestibular signaling and reduces body loading, driving sensory reweighting. The unloading effects can be modelled using head-down tilt bedrest (HDT). Artificial gravity (AG) has been hypothesized to serve as an integrated countermeasure for… read more here.

DOI: 10.1038/s41526-024-00405-4
Abstract: This study evaluated the acute and chronic effects of intermittent and continuous Artificial Gravity (AG) on cognitive performance during 60 days of Head-down tilt bedrest (HDTBR), a well-established ground-based spaceflight analogue method. Participants were randomly… read more here.

Abstract: Background: Reduced physical activity increases the risk for heart failure. Myocardial strain measurements capture subtle abnormalities in myocardial function. We tested the hypothesis that bedrest deconditioning produces cardiac dysfunction in healthy persons. Methods: In the… read more here.

DOI: 10.1161/hyp.81.suppl_1.p223
Abstract: Cardiovascular deconditioning, cephalad fluid shifts, and altered sympathetic activity in weightlessness may elicit changes in vascular structure and function akin to vascular ageing. Head-down tilt bedrest is an established terrestrial model for weightlessness and elicits… read more here.

DOI: 10.3389/fphys.2022.1008508
Abstract: Although a number of studies have examined cognitive functions in space, the reasons behind the observed changes described by space research and anecdotal reports have not yet been elucidated. A potential source of cognitive changes… read more here.
