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 was already practiced by the ancient Egyptians, ancient Greeks and the ancient Irish people, although modern pole vaulting, an athletic contest where height is measured, was first established by the German teacher Johann Christoph Friedrich GutsMuths in the 1790s. It has been a full medal event at the Olympic Games since 1896 for men and since 2000 for women.
