Kenyan high jumpers MAY 29 2013
This is a video of a pair of Kenyan high schoolers competing in a high jump contest, skillfully using a throwback technique rarely seen these days.
Cool, right? They're using a scissors-jump technique that was popular in international competitions prior to the early 1900s, when landing areas were sand pits rather than the huge foam pads you typically see today. Various techniques followed the scissors-jump, with each making higher jumps possible until Dick Fosbury invented his Flop in 1968. All international competitors use the Flop today.
Interestingly though, the Fosbury Flop is not the instantly disruptive innovation I'd always thought it was. Fosbury started sailing over the bar backwards as a senior in high school in the mid-1960s. He refined his invention for years until his gold medal at the 1968 Mexico City Olympics attracted the attention of other jumpers, who recognized the potential of the technique. But if you look at the progression of high jump world records, there was no huge jump (sorry) in record heights because of the Flop. Ten years after the Flop's big-stage debut at the Mexico City Games, the world record holder Vladimir Yashchenko still used the straddle technique. And in the 1980 Olympics, three high jump finalists didn't use the Flop. Like most new promising technologies, the Flop took time to catch on, even though 45 years on, it's the clearly superior technique. (via @dunstan)
