Figure skating jumps
Jumps are referred to by how many times the skater turns in the air. One revolution (one and a half for the Axel) is a "single" jump. Two revolutions (two and a half for the Axel) is a "double" jump. Three revolutions (three and a half for the Axel) is a "triple" jump. Four revolutions (four and a half for the Axel, although this has never been done in competition) is a "quadruple" or "quad" jump. The first triple jump landed in competition was a loop jump. It was landed by Dick Button in 1952. The first quadruple jump landed in competition was a toe loop jump. It was landed by Kurt Browning in 1988. Currently, men in world-class competition usually attempt a full set of triples and sometimes one or two quadruple jumps in their free skating programs. Triple Axels are rare for ladies, and quadruple jump attempts even more so.

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.
