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.
Axel jump
The Axel is a figure skating jump with a forward take off. It is named after Norwegian figure skater Axel Paulsen who, in 1882, was the first skater to perform the jump. Compared to other common figure skating jumps, an Axel has an extra ½ rotation in the air because of its forward take off. Most skaters perform the jump with counterclockwise rotation, taking off from the left forward outside edge and landing on the right back outside edge. The Axel can also be done as a double jump with 2½ rotations, or as a triple jump with 3½ rotations, or a quadruple Axel with 4½ rotations, but no skater has yet accomplished a quadruple Axel in competition.
