Quad (figure skating)
A quad, or quadruple, is a figure skating jump with at least three but less than four revolutions. Most quadruple jumps have 3 1/2 revolutions; the quadruple Axel has 4 1/2 revolutions, although no figure skater to date has completed this jump in competition. The quadruple toe loop and quadruple Salchow are the two most commonly skated in the discipline. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not having one in a program has come to be seen as a severe handicap. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. In 2002, Miki Ando became the first woman to do so, and she remains one of only two women to have landed a ratified quadruple jump in competition.

During the early 1990s in Brazil, Mariana Nogueira, Glenda Koslowski, and Stephanie Petterson set standards that pushed women's bodyboarding to a world class level. Stephanie Petterson won the first official World Championship of Women's Bodyboarding at Pipeline in 1990. It was the first women's event ever held there and initiated the longest running women's wave sport event in the world. 2009 marked the event's 20th anniversary.
