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.
Nathan Chen
In January 2016, Chen made history at the U.S. Championships by becoming the first American man to land two quadruple jumps in the short program. On January 24, he became the first man in the world to land four quadruple jumps in a long program. He finished third overall behind Adam Rippon and Max Aaron, who landed zero and two quads, respectively, reigniting the debate over whether artistry should trump athleticism in figure skating scoring. While attempting a jump during exhibitions on the same day, Chen sustained an avulsion injury to his left hip, leading to surgery on January 27.
