Alpine skiing in the snow season
First, the characteristics of alpine skiing
1. The normative alpine skiing is a skiing program where people step on a ski with both feet and ski poles in both hands and ski down the hill. Alpine skiing as a special project is first known as "alpine ski" in the European Alps.
Alpine skiing is a sport of snow on the slopes of nature, with its distinctive natural attributes. Alpine skiing is the symbol and essence of skiing. It is the main item of popular skiing.
2. Alpine skiing features:
(1) The force of alpine skiing is mainly gravity. The main force that the human body slides down from the mountains to the mountains is the gravitational force of the earth. It does not require much internal force for the human body. This is a remarkable feature of alpine skiing.
(2) The conditions for alpine skiing are complex and changeable. The terrain is complex, snow quality is different, conditions are variable, and they are greatly affected by natural conditions. Skiers must adapt to these situations from time to time. This is an important feature of alpine skiing.
(3) The "integration" of ski equipment and people is another characteristic of alpine skiing. Alpine skiing is a sports program that utilizes skis, ski boots, anchors, ski poles, and other special equipment to transmit power from the snow to the body. The body's kinetic energy is then transmitted to the snow surface. These are accomplished through ski equipment, otherwise the skater cannot maintain balance. So we can think of the snowboard as a part of the human body, and the snowshoe and the fixture are the “mediators†between the construction of the human and the snowboard, plus the structure of the snowboard and the characteristics of changing the shape of the snowboard. The characteristics of integration are even more pronounced.
Second, suitable for the public alpine skiing project
Although the slewing and the big swing in the alpine skiing project are technically strong projects, the turning skills of the participants are more demanding, but the taxiing distance is shorter, the gap is smaller, the speed is lower than the downhill, the super-large gyration is relatively slow, and the degree of safety is relatively low. Well, it is suitable for carrying out in the public. The Downhill and Super Slalom programs in the competition do not advocate the development of mass skiing.
Third, the basic classification of alpine skiing technology
The basic techniques of alpine skiing include downhill and turning, as well as deceleration and stoppage techniques and snowboarding.
The downhill technology includes parallel straight downhill of double plates, straight downhill plowing, and inclined downhill and horizontal sliding down.
Turning techniques include plough-type turning, semi-plough-type turning, double-plate parallel turning, skip-type turning, boarding-type turning, and carbine turning.
The deceleration and stop technologies include plough-type brake stop, roundabout turn stop, and parallel stop of double plates.
Snowboarding slope climbing techniques include double-board slopes, eight-character slopes, and winding slopes.
Fourth, the function and charm of contemporary public skiing
Skiing (including snow, snow, and snow) is good for fitness, is conducive to temperament, is conducive to enhancing cold resistance, is conducive to exercise a strong will, is conducive to disease prevention, is conducive to maintaining body shape (weight loss) No matter if you are male, female, old or young, you can enjoy the fun and charm of skiing in skiing. It has great attraction for people and participation is very wide, especially for alpine skiing.
Due to the fast, spectacular, thrilling and changeable characteristics of alpine skiing, it has been regarded as the essence and symbol of skiing sports and is the main item of mass fitness and skiing tourism. The variety of ski technologies and their variety of colors make them suitable for use in a variety of environments. This not only allows the skiers to develop their body balance, but also promotes effective training of the central nervous system, cardiopulmonary function, reaction judgment ability, and balance agility.
The low-temperature ski environment will also enhance people's courageous and tenacious spirit, their willingness to fear the cold, and their ability to adapt to external conditions. In the long silver slide, the accumulated fat and sugar in the body will quickly become heat energy to be released and consumed. This will refresh the brain and clear away the lungs, prevent and treat heart and brain diseases, respiratory diseases, obesity, depression, and fatigue. Other diseases are very effective.
Skiing away from the hustle and bustle of the city, skiing is in close contact with nature in the snow-capped mountains and in the snow-covered forests. Snow-white skies, fresh air, bright sunshine and a wide field of vision allow you to enjoy the unpredictable winter wonders. Skiers plunge themselves into the “blonde,†blending with mountains, forests, and snow. They dance with snow and enjoy the infinite joy of nature in winter. They immediately feel relaxed and happy. With fatigue will be washed and net, purify the body in nature, cultivate sentiment.
Fifth, the relationship between various technologies of alpine skiing
1. The content of the ski sport is rich and varied, and the ski technology is varied. There are flat technology, downhill slide technology, turning technology, slope climbing technology, jumping technology, and each category contains many specific technical items. For instance, alpine skiing is a ski sport that descends from the top of the mountain to the mountains. There are thrilling downhills, attractive turns, spectacular vacancies and flying...sometimes dazzling and sometimes stunned.
2. Among the dozens of technical movements included in alpine skiing, there are intrinsic links between them. Therefore, in the technique of learning alpine skiing, under the premise of systematicness, it is necessary to start from the basic technology and improve from the key technical aspects. This will in turn promote the continuous growth of ski capabilities. Basic technologies include: basic skiing posture, straight downhill, plough-down, ramp-down, cross-slip and so on.
The key technologies include: plough-type turning, parallel turning of double plates, new sliding method of large head plates, and so on.
The deeper the understanding of the interrelationships between the various technologies of alpine skiing, the greater will be the benefits.
Six, two skis plate type, position and track
1. Different ski forms require two skis to have different shapes and positions. Due to the different shapes and positions of the two skis, different skids will be formed on the snow surface.
2. As the double boards slide straight down, the two snowboards slide down parallel to the roll-off line to form two symmetrical straight-line board traces. In the semi-plough type, the left and right asymmetrical board traces are formed due to the different types and positions of the two skis. In parallel-sliding downhill of double plates, the plate traces form an angle with the fall-off line, and the left-right asymmetry.
3. During the turn of the two snowboards, the board trails formed are like semilunar-shaped arcs (no arc-shaped tracks such as ice climbing and step-type turning). The smaller the angle between the direction in which the snow board runs in the turn and the roll-off line, the less the resistance, the faster the gliding speed, and the slenderness of the board trace. On the other hand, when the snow board is turning, the board type and position are The larger the lateral factor is, the larger the area of ​​the formed trace is, and the longer the distance between the inner edge (inner arc) and the outer edge (outer arc) of the trace, ie, the width of the trace becomes wider.
4. There is a clear difference between a super-big turn or a big turn with the shape and position of a small turn, so the formed board traces are also different.
5. The skier's ability to maneuver the skis is mainly to change the shape and position of the skis in time, and to achieve the purpose of skidding or turning, acceleration or deceleration. The appearance of big snowboards has reduced the difficulty of skiers' manipulation of the shape and position of two skis.
