Deciphering the speed charm of "F1 on Ice"

  Our reporter Kong Ning Deng Fangjia

  In the middle of the night on the 21st, the "Meet in Beijing" 2021-2022 International Bobsleigh Federation Sled World Cup Yanqing Station competition came to an end.

This competition is the first time that a sled World Cup level event has come to China. China Central Broadcasting and Television Headquarters conducted a live broadcast of the competition. This is the first time that a Chinese TV broadcast production team will broadcast a sled event.

Through this broadcast, sledding, the ice and snow sport known as "F1 on Ice", will have a complete opportunity to showcase before the opening of the 2022 Beijing Winter Olympics in front of Chinese audiences.

  Match timing is accurate to the millisecond

  Sledding is one of the fastest events in the Winter Olympics. The fastest speed can exceed 130 kilometers per hour. For example, the champion of the men's single sledding event of the World Cup of sledding and the limit of the German player Johannes Ludwig in the competition The speed is 132.73 kilometers per hour.

  In the case of such a fast speed, the judgment of the results is required to be very accurate, so the International Snow Sledding Federation requires the timing of the sleigh race to be accurate to one thousandth of a second (millisecond).

Don’t underestimate 0.001 second. According to Kotans, an expert from the International Snowmobile Sled Race Organization who came to Yanqing this time, the sliding distance of 0.001 second in the sled race is about 4 cm, which is enough to determine the outcome of the race.

  The Chinese athlete Fan Duoyao, who created the history of Chinese sled sports in this World Cup and broke into the World Cup level for the first time, thrilled to break through the line with an advantage of 0.001 seconds in the qualifying competition and advanced to the competition.

  In addition, at the 2018 PyeongChang Winter Olympics, Ludwig, the champion of the men's single sledding event at the Sledding World Cup, was only 0.002 seconds ahead of the fourth place to win the bronze medal. This shows that the sledding performance must be accurate to the millisecond. sex.

There is a huge difference between the so-called millimetres.

  The German team has absolute dominance

  Although Chinese player Fan Duoyao made a historic entry into the men's single sled event in this competition, it must be noted that there is still a certain gap between Chinese players and the world's top athletes.

In the men's singles sled event, Ludwig's total victory was 1:54.597, while Fan Duoyao's total score was 1:59.038, a difference of 4.441 seconds.

This time difference is reflected in the distance of tens of meters on the track.

  In this competition, the top three men's sled events were all German players. After the game, a Chinese reporter asked: "What is the reason for the German team to achieve such a good result?" Felix, the German player who won the second place ·Loch said: "First of all, we have a strong logistics team. Second, we have adapted to the track well and designed the taxi route in advance. However, we should owe this result to the German bobsled team in the past. Accumulated effort."

  In the team relay competition, women’s singles Hu Huilan, men’s singles Fan Duoyao and men’s doubles Huang Yebo/Peng Junyue played on behalf of the Chinese team, and finally ranked ninth with 3:14.521. The Austrian team won the championship with 3:06.953. The US team won the championship with 3:06.953. At 3:07.328, they won the runner-up, and the Italian team won the third place with 3:07.331.

  In addition to the German team, athletes from Austria, Russia, Latvia, Italy, the United States and other countries also performed well in this World Cup of sledging. These countries are all powerful countries in sledging.

  Players must maintain a certain body fat rate

  In general cognition, the lighter the weight, the faster the speed.

However, many viewers who watched this game through the TV broadcast found that the sled athletes are not all that capable, or even "slightly fat".

  In fact, this is because excellent sled athletes need to maintain a certain body fat rate.

For example, the body fat rate of male sled athletes should be kept at about 20%, so that when the sled gliding produces vibration, the body fat can produce a kind of "flipping up" effect, reducing friction in a very short period of time and reducing the sliding time.

  Moreover, a certain body fat rate can help players control the sled in the ups and downs.

There is a certain weight pressure to ensure that the sled remains relatively stable.

Even so, the scenes of tobogganing in the competition are endless.

German players Egert and Beneken believe that the "Snow Dragon" circuit is excellent and difficult. "The end of this circuit is harder than the beginning because you can't feel the pressure at the corner."
