Figure Ice Skating Acrobats

• Rotations and combinations
The number of rotations performed in the air for each jump determines whether the jump is a single, double, triple, or quadruple (known commonly as a "quad"). Senior-level male single skaters perform mostly triple and quadruple jumps in competition. Triple jumps other than the Axel are commonly performed by female single skaters. Only one female skater, Miki Ando, has been credited with a quadruple jump in international competition.
In addition to jumps performed singly, jumps may also be performed in combination or in sequence. For a set of jumps to be considered a combination, each jump must take off from the landing edge of the previous jump, with no steps, turns, or change of edge in between jumps. Because of this, the only two jumps that can be performed as the second or third jump in a combination are toe loops and loops, because they take off from the right back outside edge.
To use other jumps on the back end of a combination, connecting jumps such as a half loop (which is actually a full rotation, but lands on a left back inside edge) can be used, enabling the skater to put a salchow or flip at the end of the combination. In contrast, jump sequences are sets of jumps, which may involve steps or changes of edge between the jumps.
