How can skiing judge the quality of snow?

Generally speaking, due to the different meteorological conditions when it snows and after it snows, the snow quality will present many forms. There are mainly 60 kinds of artificial snow, such as compacted powder snow and snowy road snow. The skiing skills used in each kind of snow are different. The following is to introduce the judgment method of skiing on snow quality, hoping to help you.

Judgment method of snow quality in skiing

In China, because most ski resorts are built in the northern inland, they are not affected by the ocean monsoon and have the characteristics of dry, cold and windy air. The forms of snow are mostly powder snow, shell snow, ice snow and slurry snow.

At present, the ski resorts in China are mainly snow trails mixed with the above snow. The snow in the morning is in the form of ice-like snow with a thin hard ice shell on the surface. The friction between the snow surface and the snowboard is very small, and the snowboard does not need waxing, so the skiing speed is very fast, and skiers should have certain skiing skills.

After ten o'clock in the morning, with the temperature rising and the sun shining, the surface of the snow slowly melts, showing the shape of powdery snow, which is most suitable for skiers, neither soft nor hard, and it is very comfortable to slide.

In the afternoon, under the irradiation of sunlight and the constant rotation of skis, snow appears in the form of slurry snow, which is sticky and increases friction. It is easier for beginners to control skis when skiing on this kind of snow. Skiers with good skills can wax the bottom of skis to reduce the sliding resistance.

After the new snow falls, if it is not stirred and compacted by the snow maker, a hard shell will form on the surface of the snow in a few days. Skiing in this kind of snow requires skiers to have greater forward momentum to break through this layer of snow.

This kind of snow is generally on the higher and steeper high-order snow trails that skiers can't reach, so skiers are required to have higher technical level to slide on this high and steep snow surface, which requires greater forward momentum. Once you master the skills of controlling it, it will be interesting to watch the broken snow shell flying in the air.

The benefits of skiing in winter

1, skiing-flex your body.

Skiing is a full-body exercise, which can exercise and improve the nervous system in all directions. It not only brings you the enjoyment of speed, but also exercises your balance, coordination and flexibility. The essence of skiing is to master the process of balance, find the balance point in the constant switching of the center of gravity, and make beautiful movements.

This kind of enhancement of balance ability can't be obtained by running and aerobics. Closely related to balance ability is coordination ability. Only when all parts of the whole body are fully coordinated can we achieve the best balance effect in gliding. In the process of skiing, all joints of the body need to cooperate.

Therefore, skiing can exercise almost all joints of human body, such as head, neck, hands, wrists, elbows, arms, shoulders, waist, legs, knees and ankles. So that the rigid body can enhance its flexibility.

2, skiing-strong cardiopulmonary function

Skiing, like running and swimming, belongs to aerobic exercise, which can enhance cardiopulmonary function. Especially in fast or even fast sports, the exercise of cardiopulmonary function is more obvious, and the effect of this exercise is particularly prominent in outdoor skiing.

In the face of those slides calculated in kilometers, only strong vital capacity and good cardiovascular system support can we persist in skiing for a long time. In addition, exercising in the cold air of the ski resort is also a test of the oxygen delivery system of the human body, which invisibly exercises the ability of cardiovascular contraction and expansion.

3. Relieve "Winter Depression"

Some people will become melancholy, depressed, easily tired, inattentive and inefficient in winter. Experts call this seasonal disease "winter depression".

According to relevant data, people who work indoors all the year round, especially those mental workers who are in poor health or rarely take part in physical exercise, and those who are usually afraid of the cold in sensitive person, are more likely to suffer from "winter depression" than the average person.

The most basic way to change depression is exercise, especially outdoor activities, and outdoor skiing is the right medicine. People who have tried "skiing to solve their worries" have a lot of burdens in their hearts every time they finish skiing, especially when they slide down quickly. The feeling of relief cannot be described in words.

Matters needing attention in winter skiing

1. Skiing requires high cardiopulmonary function, so aerobic training is essential. Grasp the intensity of exercise to avoid catching a cold or slipping from a tired state due to repeated sweating.

2. It is easy to ignore hydration when skiing. Drink water regularly during exercise. If you are thirsty, you are seriously short of water.

3. The movement sequence follows the principle of large muscle group first and then small muscle group.

4, beginners should pay attention to step by step, do what you can, and rest for two or three minutes after each action.

5. Start comprehensive muscle training three weeks before skiing.

6. Do three or four groups for each movement, with each group 10 to 15 times.
