During the 1964 Olympics a new technology was used in the sporting events for the first time: Fiberglass pole vaults. These new pole vaults were fabricated by using fiberglass which is a much lighter substance and much more flexible. The new lightweight construction, flexibility and strength of the fiberglass made it possible for athletes to convert their running speed into greater heights when vaulting. This new innovation led to new records set in the pole vaulting competition as well as a new standard in pole vault construction.
