Snowboarding - kind of skiing, rafting down the snow slope and takzhevsholnenie acrobatic elements on a special semi-oval Trues se - polutrube (halfpipe). A special board - wide edged skis with bindings for the feet across the line of motion. With the passage of half-tube with a total length of 120 m athletes after typing speed go up over the edge of the track for vsholneniya jumps, spins and other elements.
The program of the Olympic Winter Games with the length of the route in 1998, giant slalom - 800-1000 m elevation - 150-300 m (in Nagano - 200 m), width - not less than 20 m, the number of gates - at least 20, the distance between them is not less than 10 m, the distance between the poles gate - 4.8 m.
Competition assessment is carried out five judges, each of which may expose the athlete to 10 points for the acrobatics, the rotation amplitude flight technique elements and a touchdown. The winner is determined by the total points. After two qualifying rounds to reach the final 16 men and 8 women. Place in the final amount determined by poppok.
Each country may enter 14 athletes, but not more than 8 persons of the same sex, as well as up to 4 athletes per event. The selection is carried out by rating athletes established FIS.
- Giant slalom men;
- Women's giant slalom;
- Halfpipe women;
- Halfpipe men.
Board, hardware and shoes chosen depending on riding style. To quickly slide on the slopes and at the same time to make quick and technically turns needed hard set of equipment: a narrow board and boots like skiing. For those that prefer to soar into the air from a springboard or natural puffing, performing difficult stunts, needs soft equipment. Attachment should be soft, with an average low heel and backdrop.
Length of the board depends on the place of riding: in the mountains is better to use a longer board, and in the suburbs shorter. An important role is played by the turning radius of the board. For beginners, it is recommended to ska with an average radius of the th turn: from 7.6 m. To 8.2m. When selecting the boards should consider its shape, width and stiffness. There are two types of boards:
1. twin (more HashTable its twin-tip) is characterized by the same tail and nose. These boards are very enny maneuver in any kind of riding.
2. directional implies a different nose and tail. In this case, most of the time one foot must be in front.
Another factor that falls under the category of forms -Contact length (area). The larger it is, the more carving oriented will board. Fristaypovye boards usually have a short or medium length of contact, while the speed pattern - a large or very large. High-speed board must keep the rotation at high speeds, this is achieved by a large dip edge into the snow. To ride fast coming long board to fly and spin - short.
Board width is important for two reasons. Firstly, the larger shoe size, the larger must be the board. Medium and large width reduces contact with the snow shoes and gives the best response of the board during the transition from edge to edge. Average width gives the best balance between a small contact with the snow and the transition from edge to edge. Narrow width provides a very fast transition from edge to edge and the best ability to rotate when setting the legs at a wide angle. Ultranarrow width allows lightning fast turn over, minimizing the time for tilting.
Rigidity - is another factor that influences the behavior of the board. Soft plaque is better behaved at low speeds than rigid. Speed board - tough, which allows them to carve and maintain speed cornering. The flexibility of the board is also dependent on the weight and height of the rider. Easy rider can buy the board more flexible to compensate for low weight.
You need to check that all equipment is suitable to each other, were combined. As clothing is best to use loose pants and a jacket with a hood and buy a so-called skirt - a special valve that protects the back of the snow. Hands should be protected waterproof Signet or mittens. Snowboarder useful as a backpack, goggles, mask, metal thermos flask set paraffins, telescopic blade to build ramps, kantorez.
The history of the emergence of snowboarding.
Snowboarding originated in the 1960s., When an American slalom Jay Barton demonstrated downhill for the invention of the ski board (snow b horde) kotorpch * immediately interested ski manufacturers. Was created by a professional international Federation (ISF), competitions were held with awarding the winners of the world title. But only in 1995 was established by the International Ski Federation (FIS) Technical Committee on snowboarding. In 1996 was the first province Eden and the world championship.
The program snowboarding - two types of events: one of them is carried out on a normal ski slope, it includes variety of slalom and giant slalom; the second requires a special structure - a trough-like cut along the cylinder. In this analogy, competitions are called "halfpipe" (English, half-pipe - halfpipe).
In the "halfpipe" athlete slips down through the kind of sine wave from one section of a halfpipe to the other, making at its edges jumping-coups. Judges will evaluate the complexity and performance of the technique of jumping. The program of the XVIII Olympic Games in Nagano (1998) included "halfpipe" and giant slalom. Russian Snowboarding Championships held since 1997.
