Recalling the mainland's first participation in the Winter Olympics in 1980, athletes who did not have professional competition uniforms and could only wear autumn pants during the competition, the non-windproof and non-waterproof clothes were wet by the melted snow but could only be cold and wet on the legs, which not only made people cry.
40 years later, in 2020, the State General Administration of Sport built two large and two small wind tunnels for the research of winter Olympic clothing, and the competition uniforms were blown in the wind tunnel for a total of 900 hours.
The sportswear under this design is not only lightweight and elastic, but also has good moisture absorption, and more importantly, he can take advantage of the streamlined design of the clothing and the superior surface performance of the clothing to reduce the resistance of the air. Its surface is not as smooth as we understand, but relatively rough, through a special special-shaped structure to reverse the air flow, according to professional data calculations, this kind of competition suit can reduce the air resistance by 5 to 10% compared with the ordinary overall.
For short track speed skating, this type of racing competition, to ensure the speed of athletes when exercising and protect athletes from injury is the main thing, so the performance of keeping warm is not necessary. However, for alpine skiing, keeping warm is a must. To this end, Liu Li's team developed the fortress integrated thermal insulation system, which has twice the thermal performance of normal down jackets, and realizes full armament and intelligent warmth from head to toe.
Professor Liu Li and her team not only designed for the short track speed skating type of racing project, there are also many high-tech designs in other projects, in the field of figure skating, in order to protect the female athletes because of the jump and then stand on the hip damage caused, specially designed to help figure skating female athletes hip recovery auxiliary tools.
Alpine skiers often bruise their limbs when they cross the flag gate in the alpine skiing, and Professor Liu Li's team also designed protective equipment for them with energy-absorbing materials to protect athletes as much as possible.
The competition uniforms of each project are full of black technology, involving multiple disciplines, materials science, human mechanics, ergonomics, clothing design, etc. Behind this piece of sportswear that condenses scientific crystals is the continuous progress of our country's scientific and technological development and the continuous enhancement of national strength. Not only the Beijing Institute of Fashion designed suits for the Winter Olympic Games, but also the "hot technology" independently developed by ANTA as the official sports clothing partner of the Beijing 2022 Winter Olympics, Jialinjie, Yizheng Chemical Fiber, Hengtian Zhong fiber, Shanghai Anclong and other enterprises to provide technology, talents and supply chains for the Olympic uniforms, helping the Winter Olympics while showing the enthusiasm of the mainland people to unite and jointly welcome the Beijing Winter Olympics.
