PHYSIOLOGIC RESPONSES TO SHORT DURATION Gz.
Abstract
Subjects were subjected to Gz (positive) haversine accelerations of short duration, high magnitude on the centrifuge and their responses to peripheral lights have been recorded. Whereas, most subjects lost the peripheral lights during the 6-second haversine, only one did so during the 4-second run. Since the acceleration is maximum one half way through these accelerations this means that a rise time to 6 Gz in 3 seconds was more effective in producing peripheral light loss (P.L.L.) than a rise to 10 Gz in 2 seconds. The data thus indicate that the response tends to become independent of maximum Gz and become more a function of the duration of the acceleration. With the shorter duration haversine (10 and 8 seconds) the response tends to occur after maximum Gz when acceleration is decreasing. (Author)
