This article briefly reviews the fidelity of ground-based methods used to simulate human
existence in weightlessness (spaceflight). These methods include horizontal bed rest (BR) …

Recent studies are reviewed, concerning the in vivo wall stiffness of arteries and arterioles in
healthy humans, and how these properties adapt to iterative increments or sustained …

Despite decades of experience from high-gravitoinertial (G) exposures in aircraft and
centrifuges, information is scarce regarding primary cardiovascular adaptations to+ Gz loads …

Recently intermittent negative pressure has emerged as a potential treatment in vascular
disease and has similarities with established experimental interventions such as lower body …

Introduction Future planetary habitats will be hypobaric and hypoxic to reduce the risk of
decompression sickness during preparation for extra-vehicular activities. This study was part …

During increased gravitoinertial (G) load in the head-to-foot direction, pressures in
dependent vascular beds are commonly raised to levels capable of distending precapillary …

The study examined intra-and interlimb variations in cutaneous vessel responsiveness to
acute and repeated transmural pressure elevations. In 11 healthy men, red blood cell flux …

The aims were to study effects of iterative exposures to moderate elevations of local
intravascular pressure on arterial/arteriolar stiffness and plasma levels of vasoactive …

Displacement of blood to the lower portion of the body that follows a postural transition from
recumbent to erect is augmented by a prolonged period of recumbency (bedrest) …
