I think there was another major issue that females score highest on too. I think it had to do with temperature, but that is a very soft memory that needs checking.<p><hr /></p></p></blockquote><br /><br />Overall, there are no significant differences in g-tolerance between male and female military pilots. There were some initial differences found, but these were attributable to g-suit fit, and body height. The g-suits were designed for males; when given redesigned g-suits, the differences went away. <br /><br />Pilot height was also a positive factor, because females are generally shorter than men, and shorter pilots generally have higher g-tolerance. When this factor was statistically controlled for, this difference went away.<br /><br />In centrifuge studies I ran or participated in, we were testing for spatial disorientation and/or motion sickness effects, and never took subjects higher than 3.5 g's. They were not specifically tested for g-tolerance. We did find a slightly lower female tolerance for motion sickness, barely significant, and it was suggested that it might be tied to the menstrual cycle. However, to determine that, we would have had to test a large number of female pilots, and there just wasn't that many in 1995. <br /><br />Here is a very readable article on these issues:<br /><br />
