The final round

He directed himself over the bar head and shoulders first, sliding over on his back and landing in a fashion which would likely have broken his neck in the old, sawdust landing pits. After he used this Fosbury flop to win the 1968 Olympic gold medal, the technique began to spread around the world, and soon floppers were dominating international high jump competitions. The last straddler to set a world record was the late Vladimir Yashchenko, who cleared 2.33 metres (7 ft 8 in) in 1977 and then 2.35 metres (7 ft 9 in) indoors in 1978. Ammong renowned high jumpers following Fosbury's lead were: Americans Dwight Stones and his rival, 5 feet 8 inches (1.7 m) tall Franklin Jacobs of Paterson, NJ, who cleared 2.32 metres (7 ft 7 in), an astounding 2 feet (0.61 m) over his head; Chinese record-setters Ni-chi Chin and Zhu Jianhua; Germans Gerd Wessig and Dietmar Mögenburg; Swedish Olympic medalist and world record holder Patrik Sjöberg; and female jumpers Iolanda Balaş of Romania, Ulrike Meyfarth of Germany and Italy's Sara Simeoni.High jump shoes are different from most other track shoes in that there are an additional four holes in the heel of the takeoff shoe, where the user can insert spikes for increased traction. These extra heel spikes aid greatly in the last four to five steps of the J-approach, allowing the jumper to run on his or her curve at a fast speed without slipping. Some high jump shoes are even more technologically developed and in addition to the extra spikes on the heel, the shoes are modified to lean the direction of the approach to provide further support while running their curve. As well as the approach, high jump shoes also help and support the jumper's takeoff. The IAAF regulations specify a maximum sole thickness for both high jump and long jump shoes; competitors in all other events may wear shoes with soles of any thickness.
