What kind of skiing do you have?

Among them, cross-country skiing is a long-distance skiing in low hills and mountains (flat, downhill and uphill account for about 65,438+0/3 respectively), while snowboarding (stepping on a wide snowboard with both feet) is more exciting and flexible than alpine skiing, which has not been widely developed in China. The standardized competitions of alpine skiing include downhill, super giant slalom, giant slalom, giant slalom, all-around and so on. There are many kinds of alpine skiing techniques, including different downhill techniques, changeable turning techniques, emergency acceleration and deceleration and stopping techniques, thrilling jumping techniques and special techniques. Generally, beginners should choose the best skiing entry scheme according to their own sports quality, age, skiing foundation, venue conditions, available time and other factors. Novices should not be hasty, casual and reckless. Because skiing is a skill manipulation in skiing, the center of gravity is not easy to control, and it is easy to form wrong movements. Therefore, from the first day of employment, under the strict guidance of professional and technical personnel, we should make posture, essentials and movements correct, start with practicing basic movements, firmly grasp the foundation of technical schools, and lay the foundation for future improvement. We should be highly aware that once the wrong posture and skills of skiing are formed, it is extremely difficult to correct them and will leave deep regret. Freestyle skiing is one of the skiing events. Mainly divided into snow skills, air skills, wild chasing and so on. Freestyle skiing was born in the 20th century, and 1988 and 15 Winter Olympics were listed as performance events. 1992 16 the snow skills (men and women) in freestyle skiing will be listed as official events in the Winter Olympics. In the late 1960s, it was created by young American pioneer skiers. At first people called this kind of skiing double skiing. Snow skills, including single snow skills and double snow skills, are competitions in which a series of snow bags are used to perform gyrations, aerial movements and downhill speeds on steep slopes. The ski resort is 200 ~ 270 meters long, 0/5 ~ 25 meters wide and 24 ~ 32 degrees sloping. The snowboard used by athletes shall be no less than1.90m for men and1.80m for women. The ranking is evaluated by the quality scores and timing results of the rotation and air movements, and the one with more scores ranks first. Aerial skills began in the early 20th century. 1928, John Carleton of the United States became the first athlete in the world to complete the snow somersault on a snowboard. 1958, Swiss ski instructor Jurell completed the somersault and turn in the slide jump. The snowboard used by aerial acrobatic athletes is not less than1.90m for men and1.80m for women. The site consists of starting area, landslide auxiliary area, transition area I, platform jumping, transition area II, landing slope and terminal area. Everyone tried to jump twice in the competition. The referee evaluates the air action score and landing action score according to the quality of the athletes' actions, and then multiplies it by the action difficulty coefficient, which is the score of a trial jump. Add up the scores of the two attempts, and the one with the most scores ranks first. Fun chase fun chase is divided into qualifiers, eighth finals, quarter finals, semi-finals and finals. All players compete in groups of four, with the top two advancing to the next round. The final "Grand Finals" determines the ranking of 1-4, and the "Small Finals" determines the 5th-8th places. Cross-country skiing is one of skiing events. The athlete glides on the wilderness snowfield with a snowboard and a pole in his hand. Because it originated in northern Europe, it is also called Nordic skiing. 1924 1 The Winter Olympic Games has been listed as an official event. Cross-country skiing is the oldest winter sport. Near the Arctic Circle in Norway, a 4,000-year-old stone carving with pictures of two people skiing was found. With the aid of ski equipment, field skiing uses basic techniques such as climbing, downhill, turning and sliding to slide on mountains, hills and snowfields. There are men's 1.6km traditional style, men's 1.6km group, men's 15+ 15km chasing race, women's 7.5+7.5km chasing race, men's individual race, women's individual race, men's team race and men's 4x6550. Men's 15 km interval, women's 10 km interval, men's 50 km collective departure, women's 30 km collective departure, women's 1.2 km traditional style, the competition routes are uphill and downhill, accounting for about 1/3 respectively. In order to give full play to speed, long, steep and sharp turns should be avoided. Alpine skiing is a specific geographical environment that produces a specific way of life. Skiing began in northern Europe, where it is often snowy and snowy, as early as 5000 years ago. Similar to other ice sports that originated in Europe, it evolved from primitive hunting and gradually became a mode of transportation, which was popular in northern Europe. Alpine downhill requires athletes to follow the prescribed route and slide down from the top of the mountain through the gate with flags inserted. This is a racing skiing competition. The length of the line is more than 2,000 meters, the slope is 5-35 degrees, with an average of 20 degrees, and the height from the starting point to the end point is 500-700 meters for men. A certain number of flagpoles are inserted on both sides of the line as various gate shapes. Red flags are inserted in men's competitions and red and blue flags are inserted in women's competitions. The distance between flag gates is 4-8 meters, and the distance between upper and lower flag gates is generally about 30 meters. Two downhill times to calculate the score and decide the ranking. Technical actions include straight downhill, inclined downhill, B-type downhill, wave downhill, plow downhill and semi-plow downhill. There are three body postures: high, medium and low. Small slalom skiing in mountainous areas requires athletes to constantly cross doors and obstacles when sliding down the mountain, and constantly turn and slide down at high speed. This is a skiing competition. The length of the race line is 600-700 meters for men and 400-500 meters for women, and the section with a slope of more than 30 degrees accounts for a quarter of the whole race. Height difference is male 140-200m and female 120- 180m. There are 55-75 men's lines and 45-60 women's lines. In the competition, when turning at high speed through various doors on the line, you need to cross the door with two feet. Knocking down the flagpole is not a foul, but it is a foul if you miss the door or ride the pole over the door, regardless of the score. Each of the two roads slides once, ranking according to the sum of the two achievements. If you foul for the first time, you can't skate for the second time. You can look at the route from top to bottom before the game, but you can't slide or cross the door from top to bottom with skis. Giant slalom is one of the alpine skiing events. Athletes should quickly turn down the road from the mountain and go through gates of various shapes. The length of men's track is 1500-2000m, and the length of women's track exceeds 1000m. The altitude difference between men and women is 300-400 meters and 250-350 meters. The slope is 15-32 degrees. Calculate the score with the time of two taxies. The design turning speed of the giant slalom is15-20m/s. In the super slalom, the ranking is determined according to the result of one slide. Downhill has the largest drop and the longest distance, and the maximum speed is 130 km. The super giant slalom is a bit slow due to the large number of flag gates. The parallel slalom of snowboarding is 936m long, with an average slope of 18.25438+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. The U-shaped pool site is a U-shaped slide, with a length of 120m, a width of 15m, a depth of 3.5m and an average slope of 18 degrees. The skateboard is softer, wider and thicker. During the competition, athletes slide in the U-shaped slide with music, and use the slide to do various rotating and jumping actions, generally 5-8 shapes. The five judges score according to the difficulty and effect of completing the action, with the highest score of 10, and the sum of the five scores is the player's score in this round. There are two qualifying rounds in the competition, and the six players before the first qualifying round directly advance to the final. The remaining players took part in the second round of qualifiers, and the top six players also won the right to the finals. Finally, 12 finalists played two rounds, and the final ranking was arranged according to the best results of the two rounds. The main movements are jumping board, jumping board, handstand, handstand, rotation and so on. Cross-country skiing was included in the 2006 Winter Olympics in Turin. The height difference of the competition venue is 100-240m, the average slope is 14%- 18%, the route length is 500-900m, the track width is about 40m, and the competition time is about 40-70s. There are snowdrifts, jumping points and sharp turns along the way, and collisions often occur. Snowboarders must overcome obstacles and complete the competition through their own skills. The final result of the competition is judged by the time to reach the finish line. There will be 32 men and 32 women participating in the Winter Olympics in Turin. In the two rounds of qualifying, each player leaves the field alone, and the top 16 players enter the 1/4 finals. Starting from the 1/4 competition, there are four players in each group, and the top two enter the next round. Skiing on the platform refers to the athletes sliding down the inclined slide of the platform with special skis on their feet. With the help of speed and jumping ability, the body jumps into the air, and the whole body flies in the air for about 4-5 seconds and then falls on the hillside. 1972 the first world ski jumping championship was held in yugoslavia. This event has been listed as a competition since the first Winter Olympics. According to the regulations of the International Ski Federation, there are two snow jumping events in the Winter Olympics and the World Ski Championships, namely, the 70-meter class and the 90-meter class. From the 9th Winter Olympic Games 1964, the platform jumping levels are unified, which are only specified to be over 70m and over 90m respectively. This not only refers to the height of the platform, but also includes the slope of the platform slide, that is, 35-40 degrees, and the length is 80- 100 meters.
