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.
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.
