Abstract

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.

摘要

心血管系统对因姿势改变引起的血压波动具有缓冲功能,但在暴露于微重力环境( microgravity , microG )后,该功能可能会失调。然而,包括其纵向过程在内的失调全貌仍不清楚。本研究的目的是确定在模拟微重力( -6 度头低位倾斜( head-down tilt , HDT ))环境下暴露 20 天期间,血压反馈调节系统随时间的变化情况。
