Abstract : With the opening of the fighter cockpit to women, it is imperative to expand the current data base of responses of females to high impact acceleration environments. It is hypothesized that since women tend to have less upper-body strength than men, they may not be able to brace their heads as effectively against the loads which occur during impact and escape. This may be exacerbated by the changing center of gravity of helmets due to technological advances (e.g., night vision, head-up displays, etc). The objective of the current experimental effort is to examine the ability of subjects of both sexes to brace against an impact acceleration in the X or Y axes, and to attempt to identify a correlation between such ability, static strength measurements, anthropometric measurements, or any combination thereof.
