Blood pressure and heart rate responses to sudden change of posture during 20 days of simulated microgravity (-6 degrees head-down tilt).
The cardiovascular function buffering the disturbance of blood pressure caused by postural changes may be deconditioned after exposure to microgravity (microG). However, total picture of the deconditioning including its longitudinal process is still unknown. The aim of this study was to determine time-dependent changes in the feedback regulation system of blood pressure as exposed to simulated microG (-6 degrees head-down tilt (HDT)) for 20 days.
