ISU Figure Skating Championships

The International Skating Union (ISU) is the international governing body for competitive ice skating disciplines, including figure skating, synchronized skating, speed skating, and short track speed skating. It was founded in Scheveningen, Netherlands, in July 1892, making it one of the oldest international sport federations. The ISU was formed to establish standardized international rules and regulations for the skating disciplines it governs, and to organize international competitions in these disciplines. It is now based in Switzerland.

Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when contested at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles, pair skating, and ice dance; the four individual disciplines are also combined into a team event, first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs, which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves.

Single skating is a discipline of figure skating in which male and female skaters compete individually. Men's singles and women's singles are governed by the International Skating Union (ISU). Figure skating is the oldest winter sport contested at the Olympics, with men's and women's single skating appearing as two of the four figure skating events at the London Games in 1908.

Pair skating is a figure skating discipline defined by the International Skating Union (ISU) as "the skating of two persons in unison who perform their movements in such harmony with each other as to give the impression of genuine Pair Skating as compared with independent Single Skating". The ISU also states that a pairs team consists of "one Woman and one Man". Pair skating, along with men's and women's single skating, has been an Olympic discipline since figure skating, the oldest Winter Olympic sport, was introduced at the 1908 Summer Olympics in London. The ISU World Figure Skating Championships introduced pair skating in 1908.

Synchronized skating is an ice skating sport where between 8 to 16 skaters perform together as a team. They move as a flowing unit at high speed over the ice, while performing elements and footwork.
