Straddle technique

The straddle technique was the dominant style in the high jump before the development of the Fosbury Flop. It is a successor of the Western roll, for which it is sometimes confused. Unlike the scissors or flop style of jump, where the jumper approaches the bar so as to take off from the outer foot, the straddle jumper approaches from the opposite side, so as to take off from the inner foot. In this respect, the straddle resembles the western roll. However, in the western roll the jumper's side or back faces the bar; in the straddle the jumper crosses the bar face down, with legs straddling it. With this clearance position, the straddle has a mechanical advantage over the western roll, since it is possible to clear a bar that is higher relative to the jumper's center of mass. There are two variants of the straddle: the parallel straddle and a diving version. With the parallel straddle, the lead leg is kicked high and straight, and head and trunk pass the bar at the same time. Charles Dumas, the first high jumper to clear 2.1 metres (7 ft), and John Thomas (silver medalist at the 1964 Summer Olympics) used this technique. Valeriy Brumel (gold in 1964) dived, his head going over the bar before his trunk. Probably the most extreme exponent of the dive straddle was Bob Avant, who cleared 2.1 metres (7 ft) in 1961. Avant's technique was close to a pure dive, with just a small knee lift on his lead leg. In 1968, an American Dick Fosbury used a new style, called the Fosbury Flop, to win the 1968 Mexico Olympics by 2.24 m (7 ft 4 in). This style spread quickly, and soon "floppers" became dominant in high jump competitions. The last world record jump...
