Чемпионат мира по водным видам спорта 1991. Плавание. Женщины. 400 м вольным стилем

This swim race features American swimming champion Janet Evans in one of her early 800m freestyle races. Spoiler alert: She won. But she also did something else. What was that? Watch the video. This was taken from a British TV channel covering the championships. I have no idea if it was ever aired on American television.
