Ice ancing is a form of figure skating which draws from the world of ballroom dancing. It was first competed at the World Figure Skating Championships in 1952, but did not become a Winter Olympic Games medal sport until 1976. As in pair skating, dancers compete as a couple consisting of a man and a woman. Ice dance differs from pair skating by severely limiting lifts, requiring spins to be performed as a team in a dance hold, and by disallowing throws and jumps. Typically, partners are not supposed to separate by more than two arm lengths; originally, partners were supposed to be in a dance hold the entire program. This restriction has been lifted somewhat in modern ice dancing.
