What does an ice sledge mean?

Sleigh is a kind of winter sport that uses sleigh as a tool and slides down the hillside along the specially built ice track with inertia after sliding.

Sleigh was first spread in northern Europe, so it is also called Nordic sleigh. 19th century roses are found in Switzerland, Austria, Italy, Germany and the United States. 1 The racing sleigh was designed and manufactured by Matisse, a mechanical expert in Saint Moritz, Switzerland, in 1887. The original structure of the sled is relatively simple, consisting of two sledges and a wooden sled weighted with lead blocks. The skid is fixed at the bottom of the skid, and there is no steering device. At the beginning of the 20th century, the sled began to be made of iron, and it was made of round iron with a diameter of1.5 ~ 2cm by bending and welding. According to the requirements of the rules at that time, the weight of the whole sled should not exceed 50 kg, the length should not exceed 70 cm and the width should not exceed 38 cm.

The main difference between sled and luge is the posture of the athlete's body on the sled. When the sled slides down, the athlete lies on his back with his feet in front, and controls the direction of the sled by changing his body posture. On the other hand, skiers lie prone on the sled with their heads forward, and use anti-skid nails installed in the front of special leather boots to control the direction or brake of the sled. During the competition, athletes must wear protective equipment, such as elbow pads, shoulder pad and helmets.

The sleigh rules have strict requirements on the site, and the design of the line must conform to the "+"letter in ancient northern Europe. So at that time, only St. Moritz was a sleigh venue that met the requirements of international rules. The line length of this station is 12 14m. The height difference between the starting point and the ending point is157m. Full line 10 turn. 1928 and 1948 bobsleigh Winter Olympics were held on this route, and the champions were won by American athlete Heaton and Italian athlete Bibiya respectively.

Only 1928 and 1948 are listed as Winter Olympics events. Since 1990s, with the rise of bobsleigh, bobsleigh has been gradually eliminated. At present, this campaign has been carried out in a few countries.
