Respiration was recorded during parabolic flight in an aircraft with a closed system spirometer. The subjects were positioned in turn in a sitting, lying, and head down attitude during the high-g phases of the flight. Shifts of mean tidal volume and of mean thoracic circumference were determined manually from strip chart recordings. A net inspiratory shift of mean tidal volume is present in more than 50 percent of all parabolas investigated during the low-g phase while 12.5 percent show the opposite result. Of all 10 parabolas with shifts of mean tidal volume, 80 percent show a decrease of mean thoracic circumference, as measured by strain gage transducer.
