Prevention of G-Induced Effects on Vision and Consciousness During Simulated Suborbital Spaceflight

Anticipatory pre-tensing of leg and abdominal muscles prevented greyout completely during the launch phase and partially during re-entry, and should be considered as part of routine suborbital spaceplane operations. Studies providing relevant data from actual flights are required. Pollock RD, Britton JK, Green NDC, Hendriksen D, Hodkinson PD, Anderton RA, Smith TG.
