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.
Pair skating
The first throw triple axel jump performed in competition was by American pair team Rena Inoue and John Baldwin, Jr. at the 2006 U.S. Championships. They also performed it at the Four Continents Championships in 2006 and the 2006 Winter Olympics. The throw triple axel is a difficult throw to accomplish because the woman must perform 3 1/2 revolutions after being thrown by the man, a half-revolution more than other triple jumps, and because it requires a forward take-off.
