Figure skating is a sport in which skaters perform a series of set movements on an ice-skating rink. The movements are performed as part of a program set to music that lasts several minutes. A program can include spins, spirals, lifts, jumps, steps, turns, etc. Programs are performed by individual competitors or by pairs of competitors, and points are awarded by a panel of judges. Competitions are held at local and national levels, and also at the international level. International competitions such as the World Figure Skating Championships and figure skating events at the Winter Olympic Games are regulated by the International Skating Union (ISU).
