This study sought to determine to what extent acute exposure to microgravity (0 G) and
related increases in central blood volume (CBV) during parabolic flight influence the …

Purpose A number of studies has well described central cardiovascular changes caused by
changing gravity levels as they occur eg during parabolic flight. limited data exists …

Systemic blood distribution is an important factor involved in regulating cerebral blood flow
(CBF). However, the effect of an acute change in central blood volume (CBV) on CBF …

Abstract Changes in gravity conditions have previously been reported to influence brain
hemodynamics as well as neuronal activity. This paper attempts to identify a possible link …

BACKGROUND: Artificial hypergravity has been proposed to prevent or treat various forms
of physiological deconditioning experienced during spaceflight. We have previously …

We examined changes in cerebral circulation in 15 healthy men during exposure to mild+
Gz hypergravity (1.5 Gz, head-to-foot) using a short-arm centrifuge. Continuous arterial …

BACKGROUND: Optimal human performance and health is dependent on steady blood
supply to the brain. Hypergravity (+ Gz) may impair cerebral blood flow (CBF), and several …

Cerebrovascular reactivity (CVR) to changes in the partial pressure of arterial carbon
dioxide (PaCO 2) is an important mechanism that maintains CO 2 or pH homeostasis in the …

We previously reported that cerebral blood flow (CBF) was reduced by even mild+ Gz
hypergravity. Regional cerebral oxygen saturation as measured by near-infrared …

The investigation of systemic blood pressure (BP) responses under partial-g conditions is of
particular importance with respect to post-space-flight orthostatic intolerance. In this study …
