This morning, in the final of the freestyle ski women's big jump at the Beijing Winter Olympics, Gu Ailing showed an incredible 1620 degree in the last jump. This was the first time she had completed a 1620-degree move at the Winter Olympics. Why is this achievement amazing?
According to CCTV science, in the current world-line big jump competition, the degree of aerial rotation of women's players basically starts from 720 degrees, and then to 900 degrees, 1080 degrees, 1260 degrees, 1440 degrees a total of 5 dimensions. The first 3 dimensions of the players can basically reach, but from 1260 degrees to 1440 degrees, the world's female players have walked for nearly 9 years.
In October 2012, Lisa Zimmermann, a 16-year-old talented girl from Germany, completed the first forward slide left turn in the history of skiing in training, with a deflection of 1260 degrees. In November 2020, Switzerland's Mathil de Grimo completed a two-week backwards, 1,440-degree deflection, while breaking history. In December 2021, Gu Ailing completed another two-week positive sliding, 1440-degree deflection rotation, creating history again.
It is understood that the action of the deflection body 1620 has never been completed before either in the official competition or in the training video that has been released. And Gu Ailing achieved it in one fell swoop and landed perfectly.
In fact, not just the big jump, the whole freestyle ski program is not easy. Freestyle skiing is a high-risk and high-intensity competition with very high technical content. Among them, the rotation action in the air can be divided into the vertical and horizontal axis of the human body and the rotation around the longitudinal axis, and while completing the difficult action, there must also be extremely high viewing, while ensuring a smooth and safe landing.
The timing of the athlete's take-off, the degree of force of the take-off, the angle of the jumping moment, the strength of the leg muscles, the strength of the waist muscles, etc., all have a great impact on the landing. There are too many uncertainties, and it can be said that freestyle skiing cannot make mistakes from the beginning.
Kudos to Gu Ailing!
