China Business Daily (reporter Jie Yuxing) short track speed skating suits, steel frame snowmobile shoes, "dragon pattern" ski suits... During the Beijing Winter Olympics, the domestic jerseys and boots of Chinese players have attracted wide attention.

The progress of my country's ice and snow sports also reflects the progress of ski equipment.

In recent years, more and more domestic brands, enterprises and universities have joined the research and development of ice and snow equipment, actively explored and achieved remarkable results.

  Ice events: Short track speed skating suits to reduce wind resistance

  At the Beijing Winter Olympics, Anta has become a brand with a very high "appearance rate".

It is reported that Anta is the official partner of the Beijing 2022 Winter Olympics and a member of the national key research and development plan “Technology Winter Olympics” key special project “Key Technologies for Research and Development of High-Performance Clothing for Winter Sports and Training Competitions”.

  In terms of short track speed skating suits, there was a certain gap between the equipment of domestic athletes and foreign countries.

In 1963, Chinese speed skater Luo Zhihuan's competition uniform was a one-piece sweater.

An industry insider told a reporter from China Business Daily, "We must solve the 'neck stuck' problem by ourselves."

  Liu Li, a professor at the Beijing Institute of Fashion Technology, said that the scientific design of athletes' clothing is the most difficult, and each country has its own "secret formula" that cannot be disclosed.

But she said that China's research and development level in aerodynamic drag reduction is world-class.

  The characteristics of short track speed skating are that speed is paramount, and the impact of equipment on athletes' movements is required to be minimized.

One of the most important indicators is to improve drag reduction performance. The better the drag reduction performance, the better the athlete's performance and the more likely to be close to the gold medal.

For this type of racing event, 0.01 seconds may determine the attribution of a medal.

  Anta introduced to a reporter from China Business Daily that in order to minimize wind resistance and improve competition performance, Anta introduced wind tunnel testing in aerodynamic research into short track speed skating.

The version is adjusted through wind tunnel tests, and a special-shaped structure is also used on the surface of the clothing to quickly divert the air. Compared with ordinary skating clothing, the resistance reduction can be increased by 5%-10%.

  In addition, short track speed skating is extremely dangerous, and athletes may be cut by sharp skates.

To this end, Anta Sports Science Laboratory also cooperated with domestic professional clothing material laboratories to produce cut-resistant fabrics, which are 15 times stronger than steel wires.

  Snow sports: steel frame snowmobile shoes and ski suit escort

  In the men's steel frame snowmobile competition at the Beijing Winter Olympics, Yan Wengang won the first steel frame snowmobile Winter Olympics medal in my country's history with a time of 4 minutes and 1.77 seconds. The result set a track start record.

Sun Fan, the leader of the national steel frame snowmobile team, said that at this Winter Olympics, the domestic steel frame snowmobile shoes injected strong support for the starting and sliding of Chinese athletes.

  It is reported that Anta has also put a lot of effort into the steel frame snowmobile shoes.

Anta told a reporter from China Business Daily that the boost to the start of the steel frame snowmobile is very critical, and a little improvement in the steel frame snowmobile shoes is enough to affect the results and cannot be taken lightly.

  It can be said that Anta's steel frame snowmobile shoes broke the monopoly of foreign brands.

Its original design of the deflector structure reduces the wind resistance of the overall shoe body by 10%; the design of 3D printed titanium alloy studs can enhance the force, and the studs are arranged in a staggered arrangement, each row can be increased by 14%. of propulsion.

After the actual measurement of the steel frame sled athletes, the average increase of the shoes in the starting stage is 0.023 seconds, and the maximum increase is 0.054 seconds.

  Anta said that it has not been in contact with this project before. In order to make products that represent China's top sports equipment level within the specified time, many departments within Anta have been linked.

"Normally, it would take 18 months to develop an ordinary shoe, but this project only gave us no more than five months, and the challenge was unprecedented."

  In addition, Gu Ailing won the championship in the freestyle skiing women's U-shaped field skills competition at the Beijing Winter Olympics, and the "dragon pattern" ski suit she wore also attracted social attention.

It is understood that the ski suit adopts Anta's blazing technology, which includes core materials such as super down, polythermal cotton, and graphene.

Taking super down as an example, its down content and bulkiness are very high. The bulkiness of down on the market is about 600 or 700, and the super down reaches 840.

  Market: The R&D strength of enterprises and universities is gradually improving

  Not only Anta, but more and more domestic ice and snow equipment is on the rise.

In terms of ice sports, according to a reporter from China Business Daily, at the Beijing Winter Olympics, there are four brands of ice skates that athletes can use in ice sports, among which there is only one company from China - Changchun Bainingdun Sports Goods Equipment Co., Ltd. (hereinafter referred to as Baining Shield).

  The founder of Bainingdun, Wang Yang, was a short track speed skater who retired due to injury.

After retiring, Wang Yang still pays attention to ice sports. Out of his understanding of the needs of athletes and a deep understanding of the industry, he began to make skates.

  At the 2014 Sochi Winter Olympics, Zhang Hong won the women's 1000m speed skating championship in skates made by Wang Yang, achieving a "zero breakthrough" in China's speed skating gold medal.

  "At present, there is no gap between the skates produced by our company and foreign brands." Wang Yang told a reporter from China Business Daily that the skates made by the company have to undergo repeated tests, and professional athletes are invited to try them on, and then continue to test and run in until they meet the requirements.

  Many countries are currently buying the company's products.

On the January delivery note published by Wang Yang, the reporter found that Bainingdun's products were exported to South Korea, the United States, the Netherlands and other countries and regions.

  In terms of snow sports, some colleges and universities have participated in the research and development of snowboards and have produced snowboards with high cost performance.

For example, the high-performance snowboard products developed by teachers and students of Huaqiao University are being used in the training of the National Ski Team for the Disabled and the National Cross-Border Cross-Sport Ski Team.

  The head of the above-mentioned R&D team, Professor Jiang Feng from the Institute of Manufacturing Engineering of Huaqiao University, told a reporter from China Business Daily that the performance of the skis developed by the team has reached the average level of imported skis, but the price is only 1/5 of the imported skis with the same performance. , and is not subject to delivery time constraints.

  Jiang Feng admitted that the biggest difficulty in the research and development process was the temperature in Xiamen. They needed artificial snowmaking and a low-temperature environmental box for related tests.

However, the research team came up with a way to combine the cooler with the test equipment to reduce the loss of snow samples.

  Zhang Qing, founder of Keyway Sports Consulting Co., Ltd., told the China Business Daily reporter that the level of clothing performance is very important to athletes' training and competition, especially in short track speed skating, steel frame snowmobiles, ski jumping and other projects. All countries are conducting competitions in clothing fabrics and designs.

  Zhang Qing believes that domestic ice and snow equipment is frequently unveiled at the Beijing Winter Olympics, and even equipment that meets the requirements can be created in a very short period of time, indicating that the research and development strength of enterprises and universities has gradually improved.

In the future, enterprises and universities can continue to explore high-precision fields, including high-performance materials, environmentally friendly materials, and wearable devices for athletes training. It is hoped that more scientific research talents will transform scientific research results and help Chinese athletes achieve better results.
