Skeet shooting used to be mixed in the Olympics. Then a woman named Zhang Shan won it in the 1992 Barcelona Olympics. After her win the International Shooting Union barred female athletes from competing against male athletes. The following Olympics split male and female skeet shooting, but there weren't enough women, so they didn't have any female skeet shooting, so Zhang Khan, the former Olympic champion, wasn't able to compete at all in 1996. The subsequent 2000 Olympics did see the women's skeet shooting.
