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.
Brian Joubert
Joubert was considered a strong jumper during his competitive career. He landed the quadruple salchow jump in competition and had a consistent quadruple toe loop jump. In 2013, he became the first skater to land 100 quadruple jumps in international competition. At the 2006 Cup of Russia competition, Joubert landed three quadruple jumps in his free skate: two toe loops (one in combination) and a Salchow, the first skater to accomplish this under the IJS. Joubert has stated in interviews that he considers quadruple jumps to be important for the future of figure skating as a sport. Although the triple lutz was normally consistent for him in practice, he twice cut his right foot while picking in for the jump.
