On the afternoon of February 12, the Chinese team made history in the women’s 4*5 km cross-country skiing relay final of the Beijing Winter Olympics. The Chinese team composed of Chi Chunxue, Li Xin, Bayani Garin, and Ma Qinghua finished tenth in 57 minutes, 49 seconds and 7 seconds, setting a new record for China's best result in the history of the Winter Olympics in this event.
Cross-country skiing originated in Northern Europe and was listed as an official event in the first Winter Olympics in 1924. As a basic traditional snow event, cross-country skiing competitions are long-lasting and require high endurance, and are known as “snow marathons”. Cross-country skiing itself contains 12 events and is the largest snow event in the Winter Olympics. At the same time, cross-country skiing is also one of the competition contents of Nordic biathlon and winter biathlon.
Cross-country skiing started late in our country, and there are very few reserve talents. At the beginning of 2018, there were less than 300 registered cross-country skiing athletes in my country, and the competitive level was far behind that of the world's powerful countries.
"Traditional snow sports powers focus more on basic sports such as cross-country skiing and alpine skiing." Zheng Liangcheng said, "Only when we improve the level of athletes in these key sports will they truly recognize China The level of snow competition. ”
Cross-country skiing is a strength and endurance event in snow sports, which requires extremely high oxygen uptake, endurance, speed and other indicators of athletes. Judging from this characteristic, track and field endurance events such as race walking and middle-distance running have similarities with cross-country skiing, so they have a lot to learn from.
In 2017, the State Sports General Administration began an extensive selection of candidates. Zheng Liangcheng said that after repeated screening, a group of young athletes with outstanding comprehensive qualities were selected. At the end of 2017, after completing basic training, the Xinjiang team of the national cross-country skiing training team went to the strong cross-country skiing countries of Norway, Finland, Sweden, and New Zealand for long-term systematic external training.
In 2020, the COVID-19 epidemic swept the world, and the cross-country ski training team encountered difficulties in its external training. However, the Chinese ice and snowmen are not afraid of difficulties and challenges. "That year, our team did not ski on snow for only 27 days." In order to avoid being affected by the epidemic, the national cross-country skiing training team overcame many difficulties when training abroad. "In order to reduce the interaction between the training team and the outside world, we could only give the original foreign staff at the base a holiday, and we would do the logistics ourselves. Later, in our team, the panel repair and wax technicians could also cook and even do business. Snow grooming..." Zheng Liangcheng said, "We have implemented our own small closed-loop management. "
In Zheng Liangcheng's view, cross-country skiing and alpine skiing must win gold medals like my country's traditional advantageous projects. It takes a long time. "But now, we have made a leap forward, and we have allowed various countries to see the efforts we have made during the Beijing Winter Olympics cycle and the overall improvements in snow sports."
In this session At the Winter Olympics, China qualified for all 12 cross-country skiing events. The realization of leapfrog progress is evident. Behind the substantial improvement in the competitive level of Chinese cross-country ski athletes, the "Chinese and Western" support team has played an important role. Among them, foreign coaches and working team members can effectively help athletes grow rapidly in special aspects such as improving on-field skills and tactical levels and mastering and understanding the rules of the game. Zheng Liangcheng said: "Our technical coaches are from Norway, our waxers are from Russia, our physical coaches are from the United States, and our medical rehabilitation staff and psychological counselors are from China." With the comprehensive support of the comprehensive team , the efficient training of athletes is guaranteed.
“Having a good foundation for cross-country skiing will lead to the improvement of biathlon, Nordic combined, alpine skiing and other events.” Zheng Liangcheng said in the interview, “We attach great importance to cross-country skiing because we focus on cross-country skiing. Once the foundation is well established, talents can be provided to other sports, such as biathlon and even alpine skiing and snowboarding.”
Winning the first Nordic Biathlon Winter Olympics in history for the Chinese team. Zhao Jiawen, who has an admission ticket, first practiced cross-country skiing. Zhao Jiawen began receiving cross-country skiing training at the age of 12, and was selected to enter the national Nordic combined training team, where he began special training. Nordic combined consists of ski jumping and cross-country skiing.
At this Winter Olympics, as the first Chinese athlete to compete in this event, 21-year-old Zhao Jiawen successfully completed the competition and ranked 43rd, achieving a breakthrough for Chinese athletes in this event.
National Cross-Country Skiing Center: Follow the mountain and go green first
On the afternoon of February 12, the women’s 4*5km relay final of the Beijing Winter Olympics cross-country skiing started fiercely at the National Cross-Country Skiing Center scramble. The Russian Olympic Committee team won the gold medal in 53 minutes and 41 seconds. As one of the four competition venues in the Zhangjiakou competition area, the National Cross-Country Skiing Center will undertake competitions in 15 cross-country skiing and Nordic combined events during the Beijing Winter Olympics. Among them, all 12 gold medals in cross-country skiing were produced at the National Cross-Country Skiing Center, while the Nordic combined competitions were held at the National Ski Jumping Center and the National Cross-Country Skiing Center respectively.
The National Cross-Country Ski Center is located in the valley on the southeast side of Taizicheng area, Chongli District, Zhangjiakou City, Hebei Province. It covers an area of ??106.55 hectares and has a venue operation comprehensive area, an athlete comprehensive area, and venues from west to east. Technical building, venue media center and broadcast comprehensive area. The total length of the venue track is 9.7 kilometers, which is divided into a competition track in the east valley and a training track in the south valley. The venue's technical building has a construction area of ??4,890 square meters, with one underground floor and four above ground floors. Among them, the first underground floor is a doping testing station, the first floor is mainly used for competition management functions, the second and third floors are the platform and the Olympic family area respectively, and the fourth floor is for competition technology rooms such as arbitration, scoring and timing.
Being athlete-centered is the principle that the National Cross-Country Ski Center has adhered to since the beginning of its design. According to Cui Yingbo, deputy director of competition at the National Cross-Country Ski Center, the venue’s dedicated parking lot, wax trial area, warm-up track, training track, waxing area, locker room, and lounge are all located near the core area of ??the competition venue, with reasonable streamlines. , smooth traffic to shorten the traffic distance of each functional area and save athletes' physical energy and time outside the competition; a specially laid snow path between the waxing room and the training ground allows athletes to easily slide to the training ground.
The concept of building low-carbon venues runs through the entire process of the construction of the National Cross-Country Ski Center. From design to construction to use, green has become the background color for the construction of the National Cross-Country Ski Center. Taking the venue technical building as an example, in the eyes of Zhang Yu, chief engineer of the Winter Olympics project of China Railway Construction Engineering Group, the technical building is a key project of the entire center. “Its hollow glass curtain wall not only facilitates referees and technical officials to observe the competition field, but also better meets the venue’s strict requirements for wind pressure resistance, water tightness, and air tightness. It reduces indoor air conditioning or heat loss while also reducing air conditioning. load and reduce energy consumption.”
The National Cross-Country Ski Center’s green planning is quite ingenious. The center uses an intelligent snowmaking system to integrate all snowmaking equipment into one platform for unified management. "Intelligent snowmaking can save 20% more water than traditional snowmaking to create the same amount of snow." Changyu said that the National Cross-Country Ski Center uses mobile snowmaking, which can not only flexibly replenish the snow for different tracks in a timely manner, but also reduce water waste. , and can also realize the collection and utilization of rainwater and snowmelt water through "infiltration, stagnation, storage, purification, use and drainage". "After being treated by the silica sand honeycomb rainwater self-purification system, rainwater and snowmelt water will be used for snowmaking in winter, greening in summer, water for landscape rivers, flushing toilets, etc. Sewage from venues and infrastructure can also be fully collected and fully treated."< /p>
During the construction phase, the National Cross-Country Ski Center paid attention to minimizing its impact on the natural environment. The central track is built against the mountains, with the ruins of the Ming Great Wall right in front of it. During the construction process, the project team strengthened construction management within 50 meters of the Ming Dynasty Great Wall ruins and reminded construction workers to protect the monuments. In addition, tree vegetation is also carefully maintained. Under the premise that the construction of the track cannot destroy the surrounding native trees, the project team fully considered the characteristics of the existing mountainous terrain, combined with the requirements of the track, and cleverly planned the layout around the track to avoid the removal of trees.
After the Beijing Winter Olympics, the National Cross-Country Ski Center will be built into a mountain park and outdoor entertainment center. Taking into account post-game utilization, the venue separated functional rooms with lightweight partition walls as early as the design and construction stage. This not only facilitates post-game dismantling, but also allows the separation to be redesigned according to the plan. During the game, some of the stands and supporting facilities will be temporary buildings, which can also be dismantled and recycled after the game. In Changyu’s words: “In short, the goal is to make the Winter Olympics venues green and low-carbon throughout their life cycle.”
