Snowboarding, also known as skateboarding, originated in the United States in the mid-1960s and was related to surfing. Sherman Popan tied two skis together at 1965, and accidentally created a new "snowboard" with two feet on a whole board. Snowboarding is also called surfing in winter. In 1980s, skateboarding became popular in America, and then spread to Europe.
1983 held the first world championship, 1990 established the International Skateboarding Federation (FIS), 1994 made skateboarding an official event in the Winter Olympics, and 1998 held the first skateboarding competition in Nagano, Japan.
Introduction to sports:
In 1980s, skateboarding became popular in America, and then spread to Europe. The United States national championship was held in 1982, the first world championship was held in 1983, the International Skateboarding Federation (ISF) was established in 1990, and the International Skateboarding Federation (ISF) took skateboarding as the official event of the Winter Olympics in 1994, and the Winter Olympics in Nagano, Japan.
The parallel giant slalom is 936m long, with an average slope of 18.5438+0 degrees and a slope height of 290m. Height difference 120-200m, the flag gates are alternately placed left and right, with about 25 flag gates, and the spacing between the flag gates is at least 8m.
The two pillars of the departure gate (height 1. 10 m, base width 1.30 m) are different in height, with a pennant in the middle. At the beginning of the game, the departure door opens automatically and two players start at the same time. At the moment when the competitor crosses the flag gate, the pressure is concentrated on the toes and the chest is crossed forward. After that, the pressure is concentrated on the heel.
The main technical action is left and right rotation. Giant slalom boots are similar to ski boots, but they are more elastic. The skateboard is hard and narrow, which is easy to turn and slide at high speed. The ranking is evaluated by the speed of taxiing. According to the rules, the former 16 finalists will be promoted after adding the results of the two preliminary competitions, and then they will be eliminated. 16 will enter the top 8,14 finals, rematch and final.
In the official competition, each pair of players draws lots and conducts two preliminaries on the parallel track, and the second preliminaries need to change tracks. The time that the athlete who lags behind in the first game delays his departure is equal to the time that he lags behind in the first game. The first player to reach the finish line in the second game wins.
