The highest level of duels in the world's women's U-shaped venue, although the American player Chloe Jin failed to challenge the 1260-degree turn, but with the conventional operation of two 1080-degree turns, won the gold medal, the Chinese team three people broke into the final, but whether it is Cai Xuetong or Liu Jiayu are slightly inferior in difficulty, even if it is a 1080-degree turn, it is barely completed, but the connection series is flawed. In the future, the growth of China's veneer boards still needs to move forward steadily, and strive to improve the difficulty of action.
Snowboarding is a young snow sports, although it only entered the Winter Olympics in 1998, but in the hearts of young people, this project competition is a dazzling grasping board, full of soaring height and rhythmic high difficulty actions and tandem, so the difficulty of the action, the height of the lifting, the way of grasping the board, the overall connection is also the main reference for the referee to score.
In recent years, China's snowboard U-shaped venue progress is very fast, in the 2006 Winter Olympics, Sun Zhifeng, Pan Lei for the first time to participate, when the main action of the two was 540 degrees of rotation, which is also the mainstream difficulty of women in the world today, combined with a variety of grab boards and other actions, the competition is the connection and details and the height of the air.
With the emergence of Liu Jiayu and Cai Xuetong, since 2007, the difficulty of the Chinese team's movements has gradually increased. In this cycle, Sun Zhifeng and Liu Jiayu were able to complete a 720-degree turn, and at the World Championships that year, Liu Jiayu won the championship with a 720-degree turn, which was the first world championship of Chinese snowboard.
Since 2010, the snowboard women's difficulty has developed and broken through rapidly, the World Extreme Games is a leading event of difficulty and trend, many high-level athletes choose to unlock new moves here, the United States' Kelly Clark, that is, Chloe King's predecessor took the lead in completing the 900-degree turn, and the 2015 and 2017 World Championships Cai Xuetong won the championship, with the 900-degree turn.
Over the past decade, most athletes have struggled to overcome the 1080-degree turn, compared to the 720-degree turn, although it is only an increase of 180 degree rotation, but three weeks is more of a challenge and difficulty for women's athletes. Some experts have studied that the veneer flip and the rotating body are affected by many factors such as sliding speed, lifting height, angle of rotation, and moment of inertia.
This is an external factor, but whether the air flip and the turn can be completed, and the athletes themselves also have a lot to do with the difficulty of completing three weeks or higher, not only to meet the above conditions, but also to have excellent gliding ability, speed skills, excellent physical coordination and perfect aerial posture, of course, there are also studies that show that biomechanics, psychological quality also has a certain impact, it can be seen that the completion of this action is multi-faceted, multi-level decision, is a complex and long process.
At the 2018 Winter Olympics in Pyeongchang, Chloe King successfully used a 1080-degree turn for the first time at the Winter Olympics, pushing the difficulty of the world women's snowboard U-shaped venue to a new height. At that time, Liu Jiayu completed the two 900-degree rotation actions of the front foot and the back foot, and although Cai Xuetong was in a good training state and completed the 900-degree turn, he did not complete it in the actual competition. This Winter Olympics, Liu Jiayu won the silver medal, and Chloe Jin reached the top without suspense.
Entering the Beijing Winter Olympic cycle, Liu Jiayu was trapped and injured, and did not focus on the training on the 1080-degree turn, but continued to polish the 900-degree turn, and used the backflip for two weeks 900 degrees to turn the body, Cai Xuetong impacted the 1080 degree turn, she made a 900-degree turn at the Beijing Winter Olympics, but the 900-degree turn was flawed, resulting in the connection of the complete set of actions was not complete.
In the third round of the final, Chloe King's impact on the 1260-degree turn failed, which is the men's trend action, at present, the American post-00 has mastered the 1080 degree turn, and has a complete set of actions two 1080 degree turn connection, thriving in the women's U-shaped field, while other athletes are still trying to improve the success rate of the 1080 degree turn, while also ensuring the success rate of the 900 degree turn, the current gap is still obvious.
In the case of overcoming the difficulty of 1080-degree rotation, many players have added a combination of cork, rodeo, deflection and other combinations while completing the 900-degree rotation or 720-degree rotation, trying to use diversity to make up for the gap between the flip and the rotation, which may be a way of thinking of the Chinese team. In short, China's snowboard U-shaped venues have a long way to go, and the future still needs to polish the details in order to challenge the limits of the body and break through themselves. (Ren Xin)
