Five technical revolutions in high jumps
High jump is one of the athletics jumping events.
Also known as a high jump.
It consists of rhythmic run-ups, one-foot take-off, emptying the pole and landing, etc., and finally calculates the score based on the height that it successfully crossed the upper edge of the crossbar and determines the ranking.
The first high jump position officially recorded in the track and field history book is a leapfrog, which appeared in the track and field competition of Oxford University and Cambridge University in 1864.
That year, the British athlete Robert Koch created a “leapfrog”.
World record for the first high jump of 70 meters.
In 1895, American Sweeney improved the leapfrog, which is characterized by the athlete’s rapid body turning and sideways legs, such as scissors. This technique was created at the time.
A new record of 97 meters.
In 1912, American athlete Holling used the vertical oblique run-up at the Stanford University track and field competition, and won the championship by using the technique of body alignment and rolling across the crossbar. Holling named this technology “rolling”, which is also positiveIt was this technology that allowed humans to cross an altitude of 2 meters for the first time.
In 1923, Soviet athlete Vlotsov created the “prone” high jump technique, which was quickly accepted by track and field athletes.
At the 19th Olympic Games in 1968, 38 of the 39 high jumpers adopted this technique, which brought the application of the “prone” technique to its peak.
However, also at this Olympic Games, a new shot-crossing action began to emerge.
At the 19th Olympic Games, the 21-year-old American Fosberg passed the stroke differently. When he crossed the crossbar, he did not face down, but instead faced up and “flyed” over the crossbar. This actionKnown as the “back-over” stroke technology.
At this Olympic Games, Fosberg went 2.
The 24-meter record set a new Olympic record, and the “back style” high jump also swept the world.
In the following more than ten years, the track and field industry has not yet determined which technology is more advanced.
Until the 22nd Moscow Olympics, the Federal German athlete Weissig conquered with a backflop technique.
At a height of 36 meters, after defeating all athletes who use prone height jump, back style high jump gradually began to replace the dominant pattern of high jump technology, and prone high jump technology has gradually been left out.
