title: A system to measure lower body volume changes during rapid onset high-G acceleration.
abstract: A specialized four-channel impedance plethysmograph is described that can be used to measure calf, thigh, and abdominal volume changes during rapid onset rate centrifuge acceleration. Typical results are presented to demonstrate its application to research and the design and assessment of countermeasures to enhance man's performance in the high-G environment.
