How to recognize the ice skating sport "Three Brothers"? Lying on a sleigh, a steel-framed bobsleigh lying on the back, a bobsleigh sitting on a bobsleigh

City Express News The 2022 Beijing Winter Olympics is in full swing, "every day orange persimmons understand the Winter Olympics" have been launched, in plain language, for the "Winter Olympics whites" to popularize the Winter Olympic projects, rules, sports equipment, sports characteristics, etc., readers have said: useful knowledge has increased.

Today, we talk about the often confused ice skating sport "Three Brothers". They use the same track, sliding from start to finish; skating tools ride are a lot like; athletes wear costumes like them. But these three items can be distinguished in a simple sentence: lying on a sleigh; lying on a steel-framed snowmobile; and sitting on a snowmobile.

The three events of bobsleigh, bobsleigh and steel frame bobsleigh are all held at the National Bobsleigh Center in Yanqing, and the competition uses the same track. The length of the men's singles is usually between 1300-1500 meters, the length of the women's singles and men's doubles is usually 800-1200 meters, the width of the track is 130-150 meters, the height difference between the starting and finishing points is 110-130 meters, and there are 11-18 curves throughout the course.

Let's start with the competition tools for three events.

Sleigh, you can make up the picture of the elk pulling Santa Claus flying in the air, Santa Claus is sitting on the sleigh. The snowmobile, also known as the "Snow F1", is more like a car than a sled, with multiple shells and a "steering wheel". Steel-framed bobscars, like sleds, have only a chassis and no steering and braking systems.

The starting action of the three is also different. The sledds gain initial speed by swinging forward and backward and harrowing the ice, while bobsleighs and steel-framed snowmobiles gain their initial speed by running and pushing the hull. Bobsleigh, bobsleigh, and steel frame bobsleigh races are all affected by gravity to a certain extent, so the weight of athletes is also critical. Therefore, the competition rules have requirements for the weight of the car and the athlete, if the total weight is insufficient, the weight of the body can be appropriately counterweighted, but can not exceed the weight limit.

Let's talk about the equipment on the athletes.

Because of the need for raking ice, the gloves worn by sledders are spiked, and the rakes to find the best speed after acceleration, and then lie flat on the sled to glide, adjust and change direction through the coordinated force of various parts of the body, and slow down by adjusting the posture after reaching the end.

Snowmobilers wear spiked boots with spikes on the soles of their boots, start by running to push the snowmobile forward a certain distance to get the initial speed, and then jump into the body of the car in turn, glide in a sitting position, and control the direction of progress through the steering system.

Steel frame bobsleighers, like snowmobilers, need to wear spike boots, grab the handles of the car, push the body forward quickly, and then jump on the body, keep the head forward in a prone position, and adjust the direction of progress by controlling the body.

It is worth mentioning that these three sports are very fast in the competition, the ornamentality is high, and the control ability of the athletes is particularly high. Now, with a preliminary understanding, the next time you watch the game, you will not admit mistakes. If there is no accident, on February 15th, the snowmobile women's doubles competition, there will be a figure of Zhejiang athlete Du Jiani, remember to cheer for her fellow countrymen!
