supports: The Norwegian Skating Association (NSF) is the main skating authoritative body in Norway. It oversees speed skating, figure skating, short track speed skating on ice and more recently inline and roller skating.  Figure skating is a sport in which individuals, duos, or groups perform on figure skates on ice. It was the first winter sport included in the Olympics, in 1908. The four Olympic disciplines are men's singles, ladies' singles, pair skating, and ice dancing. Non-Olympic disciplines include synchronized skating and four skating. From novice through senior-level competition, skaters generally perform two programs (short and long) which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves. Speed skating is a competitive form of ice skating in which the competitors race each other in travelling a certain distance on skates. Types of speed skating are long track speed skating, short track speed skating, and marathon speed skating. In the Olympic Games, long-track speed skating is usually referred to as just "speed skating", while short-track speed skating is known as "short track". The ISU, the governing body of both ice sports, refers to long track as "speed skating" and short track as "short track skating". Terje Andersen ( born 4 March 1952 ) is a former speed skater and president of the Norwegian Skating Association . Andersen was a typical middle distance skater , his best achievement being one bronze medal from the 1980 Winter Olympics of Lake Placid . Andersen participated several times in the World Sprint Championships , finishing fourth in 1981 , and sixth in 1978 . His best placing in an allround championships is a twelfth place at the World Championships of Oslo in 1975 . He represented Tønsberg TF and Holmestrand og Botne SK . He was president of the Norwegian Skating Association from 1997 to 1999 , and again in 2003 to 2007 . Roller skating is the traveling on surfaces with roller skates. It is a form of recreational activity as well as a sport, and can also be a form of transportation. Skates generally come in three basic varieties: quad roller skates, inline skates or blades and tri-skates, though some have experimented with a single-wheeled "quintessence skate" or other variations on the basic skate design. In America, this hobby was most popular, first between 1935 and the early 1960s and then in the 1970s, when polyurethane wheels were created and "Disco" oriented roller rinks were the rage and then again in the 1990s when in-line outdoor roller skating, thanks to the improvement made to inline roller skates in 1981 by Scott Olson, took hold.
