What u-court techniques do you know?

After the qualification of freestyle skiing women's U-track skills in Beijing Winter Olympics, China's Gu Ailing ranked first and easily advanced, while Zhang Kexin and Li ranked fifth and seventh respectively, and also successfully reached the final. In this season's International Snow Federation World Cup, Gu Ailing performed strongly in U-shaped court skills, winning all four championships, and winning the crystal ball symbolizing the champion for the first time in her sports career. At the Beijing Winter Olympics, she was also considered as the biggest favourite to win gold in this project.

What do athletes need in the competition? Fly 5-7 times in the air and perform aerial skills. Flying height, difficulty of continuous performance, diversity and innovation are the keys to winning the gold medal. Different from competitive gymnastics or figure skating, slope obstacle, U-shaped ground and big platform are not scored separately according to each action, but judged by the judges according to the overall impression of the athletes after completing the action. The score ranges from 1 to 100, and the average score is finally taken. Of course, this does not mean that judges in different countries can play freely. They should grade athletes according to their creativity and difficulty.

Athletes who make mistakes will be deducted. Minor faults (1- 10) include flat landing, falling to the platform, pushing and sliding, slight hand touching snow and other physical instability. Moderate errors (1 1-20 points) include completely stopping, dragging snow with hands open, obviously touching snow with hands, slightly touching snow with buttocks, and adjusting the sliding direction of the snowboard after landing. Major mistakes (2 1-25) include obviously touching the bottom, touching the body and falling down completely.

"This venue is great, and it slides very fast. These days, because of the obstacles in the preliminaries and finals, the skill training of the U-shaped stadium is a challenge for me. After Gu Ailing's arch-rival, Estonia's Kylie Sildaru scored 87.50 points in the first slide, she gave up in the second slide and finally advanced to the third place. Rachel Carker of Canada ranked second with 89.50 points, while defending champion Cathy Sharp of Canada ranked sixth with 86.25 points.
