[Winter Olympics ＂cold＂ knowledge] How difficult is freestyle skiing？ From 1260 degrees to 1440 degrees, women athletes all over the world have walked for nearly 9 years.

　　CCTV News:We have a strong feeling in watching the freestyle ski jumping competition, which is the visual impact and aesthetic feeling. But at the same time, we also see that many athletes, including world-class top players, will make mistakes and fall. Indeed, freestyle skiing has high intensity and higher risk factor. How difficult is this project?

　　Big platform and aerial skills, snow skills, U-shaped field and slope obstacle skills all belong to freestyle skiing. Among them, the big platform is the most difficult. Athletes need to slide down the slope and rush to the platform, but also perform aerial stunts such as somersault and gyration at the end of the platform by inertia, which is extremely risky.

　　At present, in the world’s first-line platform competition, the degree of female athletes’ aerial rotation basically starts from 720 degrees, and then reaches 900 degrees, 1080 degrees, 1260 degrees and 1440 degrees, a total of five dimensions. Players in the first three dimensions can basically do it, but from 1260 degrees to 1440 degrees, women players all over the world have walked for nearly 9 years.

　　In October, 2012, Lisa zimmermann, a 16-year-old German talented girl, completed the first two-week off-axis twist of a female snowboarder in the history of snowboarding, officially opening the era of two cores and three and a half weeks for women’s snowboarding.

　　In November, 2020, mathilde Gremaud, a Swiss player, completed a two-week off-axis twist of 1440 degrees and broke the history at the same time.

　　In December, 2021, Gu Ailing made another 1440-degree off-axis twist with two straight slides, making history again. It took nearly nine years to make this step.

　　Why is the big platform jump so difficult? In fact, not only the big platform, but also the whole freestyle skiing event is not easy. Freestyle skiing is a high-risk and high-intensity competition with very high technical content. Take-off, aerial action, landing and taxiing, the three processes are interlocking, pulling one hair and moving the whole body. The turning action in the air can be divided into vertical and horizontal axes of the human body and turning around the longitudinal axis. While completing the difficult movements, it must also be highly ornamental, while ensuring a smooth and safe landing.

　　The timing of the athlete’s take-off, the degree of take-off, the angle of the moment of take-off, the muscle strength of the leg and the muscle strength of the waist, etc., all have great influence on landing, and there are too many uncertain factors. It can be said that freestyle skiing can’t make mistakes from the beginning. It can be seen that freestyle skiing is not just a wonderful flying jump, but there are countless invisible efforts behind it. Freestyle skiing is not so difficult as human’s awe of the Olympic competitive spirit and the courage to break through and surpass themselves. Always young, always enthusiastic, always love sports.
