Inflight Lower Limb Volume Measurement (ASTP007)
Research Area:
Cardiovascular physiology
Chronobiology
Muscle physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
During space flight, the body's fluids tend to shift from the lower body toward the head and chest. This fluid redistribution is clear from observations and confirmed in data collected from the Apollo and Skylab crews. These changes and their effects were described by crewmembers: fullness of the head, puffy faces, stuffy noses, distended veins in the neck and forehead and a noticeable shrinking of muscles.

First measured inflight on the Skylab 4 crewmembers; leg volume measurements were also performed on the Apollo-Soyuz Test Project (ASTP) crewmembers. The objectives of this study were to substantiate the volume reduction that occurs inflight, to obtain inflight leg volume determinations earlier than those obtained on Skylab 4 and to document the time course of fluid shifts by frequent leg volume measurements.
