Pole vaulting, also known as pole jumping, is a track and field event in which an athlete uses a long and flexible pole, usually made from fiberglass or carbon fiber, as an aid to jump over a bar. Pole jumping competitions were known to the Mycenaean Greeks, Minoan Greeks and Celts. It has been a full medal event at the Olympic Games since 1896 for men and since 2000 for women. It is typically classified as one of the four major jumping events in athletics, alongside the high jump, long jump and triple jump. It is unusual among track and field sports in that it requires a significant amount of specialised equipment in order to participate, even at a basic level. A number of elite pole vaulters have had backgrounds in gymnastics, including world record breakers Yelena Isinbayeva and Brian Sternberg, reflecting the similar physical attributes required for the sports. Running speed, however, may be the most dominant factor. Physical attributes such as speed, agility and strength are essential to pole vaulting effectively, but technical skill is an equally if not more important element. The object of pole vaulting is to clear a bar or crossbar supported upon two uprights (standards) without knocking it down. History Poles were used as a practical means of passing over natural obstacles in marshy places such as the province of Friesland in the Netherlands, along the North Sea, and the great level of the Fens in England across Cambridgeshire, Huntingdonshire, Lincolnshire and Norfolk. Artificial draining of these marshes created a network of open drains or canals intersecting each other. To cross these without getting soaked, while avoiding tedious roundabout journeys over bridges, a stack of jumping poles was kept at every house and used for vaulting over the canals. Distance pole vaulting competitions continue to be held annually in the lowlands around the North Sea. These far-jumping competitions (Frisian: Fierljeppen) are not based on height. In his book The Mechanics of the Pole Vault, Richard Ganslen reports that the London Gymnastic Society under Professor Voelker held measured pole vaulting events in 1826, involving 1,300 participants and recording heights up to . Other early pole vaulting competitions where height was measured took place at the Ulverston Football and Cricket Club, Lancashire, north of the sands (now Cumbria) in 1843. Modern competition began around 1850 in Germany, when pole vaulting was added to the exercises of
