(Winter Olympics asks "Ji") How to distinguish snowmobiles, steel-framed snowmobiles and sleds?

  China News Service, Shijiazhuang, December 28. During the Winter Olympics, many people were "silly and unclear" about the three items of snowmobiles, steel-framed snowmobiles and sleds.

It seems that they are all three items of sliding sports. How to distinguish them easily?

  Snowmobiles and sleds are the two major events of the Winter Olympics, and snowmobiles are divided into two types: snowmobiles and steel-framed snowmobiles.

These three sports can share the same track, and the competition system is similar.

The most intuitive difference between them lies in the equipment. The snowmobile is like a convertible car. It has not only a chassis, but also a steering wheel and a "canopy."

  So how do you distinguish between a sled and a steel-framed snowmobile?

In fact, it can be distinguished from the athlete’s posture: in the sled race, the athlete lie on his back on the sled, feet in front, head behind, and lie down while sliding; while the steel frame snowmobile is the opposite. On the snowmobile, head in front and feet behind, sliding on your stomach.

Therefore, the equipment of the sled and the steel-framed snowmobile is also slightly different, that is, the sled has two elbows on the head to facilitate athletes to put their feet on, while the steel-framed snowmobile does not.

  These three events also have the same points: first, the speed of the three events is very fast, with a maximum speed of more than 130 km/h; second, the three events are very dangerous and will "roll over" if they are not careful; finally, they all require athletes to Have the ability to obtain the maximum initial speed, and the ability to flexibly control the limbs to maintain the balance of the body or equipment to adapt to the continuous increase in speed.

Therefore, in the selection of athletes, the athletes who are taller than others and run faster are more popular.
