Part of an article, I found follows...
In addition to supporting female soldiers in training, research also produced positive findings for female pilots. If they're outfitted properly, they can handle G-forces just as well as men and may be a bit better at tolerating decompression without becoming ill.
Previously, some in the military thought that women couldn't perform as well as men in the hypergravity encountered in fighter aircraft, said Christopher Hearon, a kinesiology researcher at Texas A&M-Kingsville who studied G-forces while working for the Air Force Research Laboratory at Brooks Air Force Base. The concern was that women didn't have enough endurance to handle something called an "anti-G straining maneuver," which requires contractions of various muscle groups and rapid breathing.
"Basically, it helps return blood -- which is forced into the extremities by the high G force -- to the heart and brain, keeping the pilots from passing out," Hearon said.
If pilots can't handle the intense maneuver, they're at major risk during flights that encounter high G-force, Hearon said. Women traditionally had more trouble with the maneuver than men.
Hearon and colleagues outfitted women with newly designed anti-G suits to see if that helped. It did, and the women surprised the researchers by performing as well as the men.
