There are two kinds of sledding: bobsleigh and luge. What is the sled race in the Olympic Games?

Sleigh is a kind of double sleigh skateboard made of wood or metal, which slides down on special ice and snow lines and turns at high speed. There are two kinds of sledges: bobsleigh and luge. From the beginning of 1924 1 Winter Olympics to the present, bobsleigh has always been an event of the Winter Olympics, and the snow without rudder was not listed as an official event until 1964.

A luge is a kind of metal sleigh for four or two people, similar to a boat. The front of the sled has a steering wheel connected to the steering wheel. When skiing, athletes use the rudder and steering wheel to control the sled to slide on the artificial ice track. During the competition, the athletes quickly descended to the finish line along the ice track with various bends (slope 8- 1500m).

Sleigh appeared in 18 in the 1980s. In St Moritz, the Swiss winter ice and snow sports base, an American named Davushenda nailed two single boards together with wooden boards, and the front one was used to control the turn. As soon as this sleigh sport came out, it aroused great interest. 1888 Swiss entered Matys and made a relatively complete set of bobsleigh. The frame is made of wood and the skateboard is made of iron. After improvement, the outline of modern snow is gradually formed. 1903, the world's first snow slide was built in St. Dietrich. Since then, the bobsleigh movement has become popular in the Nordic countries.

During the competition, the athletes push the sled from the starting point, then jump into the sliding sled and use inertia to push forward. The front seat is the position where the athletes steer, and the athletes in the back seat are responsible for braking. The race is timed, and the fastest person wins. Because the sled mainly relies on inertia to push the movement, the rules strictly stipulate the weight of the sled (including the weight of athletes and other heavy objects). The weight of a two-person sled shall not exceed 375 kg, and that of a four-person sled shall not exceed 630 kg.

A rudderless snow plow is a kind of movement in which you ride (lie) on a sled and change your posture to control the sled to turn and slide at high speed. The sled is made of wood or metal, and there are two parallel skateboards on the temple surface, and the distance between the two boards is no more than 45 cm. The inclined part in front of the skateboard is flexible, but there is no brake and rudder. The luge appeared late and was invented by British skiers in 1948. It was not until 1964 that the Ninth Winter Olympics was included in the official competition. The rudderless snow umbrella is light and flexible, so it is very popular with winter sports enthusiasts.

During the competition, the athletes sit on the sleigh, grab the railing at the starting point with both hands and push it back hard, so that the snow will start to move forward. When sliding, pull the belt on the snow with one hand, and use the ups and downs of the body to change the posture of shoulders and legs, so that the sled can catch it and slide down the ice track quickly. In the single-player competition, each skater skates 4 times, and in the double-player competition, each skater skates 2 times, and the one with fast speed and short time wins. According to the rules of the competition, the weight of single-seater sled should not exceed 20 kg, and the weight of double-seater snow eaves should not exceed 22 kg. During the competition, the length of the men's rink is 1000m, the length of the women's rink is 800m, and the slope is 4-6. The skating rink has straight, left, right and various shapes.
