Salto long jump
The long jump is a long jump in which a forward somersault is performed in the flight phase . The trainer Tom Ecker is considered to be the inventor of the modern salto long jump, which he described in 1971. The technology itself was not new then; there are reports about it from the first half of the 20th century. Ecker was the first to provide a physical explanation in his publication .
In an ordinary long jump, the upper body moves faster than the lower body at the time of the jump . The jumper has to compensate for this angular momentum . In a somersault long jump, the jumper allows this turning movement; it works for instead of against the knight. When jumping, the curled body of the jumper offers less air resistance than the stretched body of a conventional jumper. While a conventional long jumper falls from his feet onto the pelvis when landing, the twisting movement of a long somersault straightens the upper body.
Ecker's publication did not attract any attention until 1973 when the American pole vaulter Dave Nielsen trained this technique and demonstrated it in Europe. This inspired other athletes, including Bernhard Stierle . In February 1974 in Böblingen he jumped 7.42 m at the South German Championships and generated a lot of media attention. The athletes thought jumps over 9 meters were possible, which would have been a new world record. The spectacular somersault technique also promised to be effective for the audience. The risk of injury to the technology was discussed right from the start, even if experts considered this to be low for acrobatically trained athletes. The World Athletics Federation was reserved about the somersault long jump because this technique did not have much in common with the traditional long jump.
The era of the long somersault jump in athletics lasted only a few months. At the request of the German Athletics Association , this technique was banned in 1974 at the Congress of the World Athletics Association in Rome without official justification.
The long somersault jump is still practiced, especially in parkour . The Guinness Book of Records shows a record of 6.18 meters there.
