Pole vaulting is a track and field event in which a person uses a long, flexible pole (which today is usually made either of fiberglass or carbon fiber) as an aid to jump over a bar. Pole jumping competitions were known to the ancient Greeks, Cretans and Celts. It has been a full medal event at the Olympic Games since 1896 for men and 2000 for women.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.
