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.
