How high is the snow quality required for alpine skiing competition venues?

Downhill skiingThe competition venue has very high requirements for snow quality, because the snow quality will directly affect the performance of athletes.

To some extent, almost all ice sports have strict requirements for snow quality, because athletes need to perform movements on the ice, and athletes' performance is very dependent on snow quality. If there is a problem with the quality of the snow, the athlete's movements will be deformed, and the athlete may even be injured as a result. If the snow conditions are very good, athletes can achieve better performance and even have a chance to break historical records.

1. Alpine skiing competition itself is very competitive.

Alpine skiing competitions are very dangerous, not only for the athletes' own mastery of movements, but also for the snow quality of the venue. In most cases, alpine skiing competitions require soft and delicate snow. When an athlete lands, better snow quality can provide the athlete with corresponding cushioning, and in this way protect the athlete's body.

2. The venue of the alpine skiing competition has very high requirements for snow quality.

The requirements for snow quality in the venues of alpine skiing competitions are mainly divided into two aspects, the first is the athlete's athletic performance, and the second is the athlete's personal health. If the conditions are really good, the athlete can get more speed and power to start, so they can have better performance. At the same time, the field will also play a certain role in protecting the athletes, and poor snow quality may lead to injuries to athletes.

3. Almost all sports have strict requirements for snow quality.

With the exception of alpine skiing competitions, almost all ice sports require good snow quality. After entering the modern society, the technology of artificial snowmaking has been further developed, and the Beijing Olympic Games has also made full use of artificial snowmaking technology, so the Beijing Olympic Games can provide athletes with excellent snow quality, and create the best sports conditions for athletes in this way! <>

The requirements for snow quality are very high, the thickness of the general snow must be accurate to 30 mm, the shape of the snow must be hexagonal, and the snow field must be 10 4 cubic meters.

The requirements for snow quality are very high, first of all, the snow must be pure, and the purity must be high, not the kind of rough snow. And the amount must be large.

The requirements for snow quality are very high, because the quality of snow affects the performance of athletes, and the performance of athletes is very dependent on snow quality.

The requirements for snow quality are quite high, and it is necessary to ensure the integrity of the venue and the smooth running of the competition.

It is very high, because if the snow quality is not high, it may affect the athletes' competition and may even be dangerous.

The difference in elevation between the start and the finish of the downhill is 800 1100 meters for men and 500 800 meters for women. The length of the route should be designed to ensure that men at the Winter Olympics.

and the best time at the World Championships is not less than 2 minutes, and the best time of the women's time at the Winter Olympics and World Championships is not less than 1 minute and 40 seconds. In order to ensure the safety of the race, in addition to planting enough red and green flags on both sides of the road, flag gates must also be set up on dangerous road sections, ramp transitions and bumpy areas, transition sections, and road sections where athletes are prone to slipping in the wrong direction. The width of the flag gate shall not be less than 8m.

Athletes must use at least one front end and both feet of skis to pass through the flag gate line in order to pass through the flag gate correctly. Oversized turning sites require undulating terrain. The width must not be less than 30 meters.

The difference in altitude between the start and finish points is 500,650 meters for men and 350,500 meters for women. The width of the flag gate is at least 6 meters for the open flag gate and 8 to 12 meters for the closed flag gate. The number of flag gates must not exceed 10% of the height difference, but at least 35 for men and 30 for women.

Rotary fields are usually inclined and wavy, with a width of at least 30 meters.

The altitude difference between the start and end points is 350 400 m for males and 260 350 m for females. The number of flag gates should be 12 15% of the height difference. The flag gate is 4 8 meters wide.

In the men's competition, more than 35 flag gates should be set up; There were more than 30 women's matches. When going downhill, there are two different types of downhill skiing.

Jumps in the slalom and alpine ski slalom. There is only one game. The minimum distance between the flagpoles of the two nearest upper and lower continuous doors shall not be less than 10m.

This project is characterized by its speed. In order to glide on an inclined plane with an average inclination of 15-30 degrees at a speed of 90-140 km, athletes need strong will and physical strength.

There is only one colored sign on the runway. After passing the prescribed track correctly, the final standings should be determined according to the order in which they reach the finish line. According to the first round of the skating race and the second round of rotation competition. Cost-benefit calculations are performed on the scores of the Glide Race and the Turn Race to get a ranking.

Each event of Alpine skiing is a solo start, and the order of departure is determined by lottery, but some events require two skis, and the order of the second start is quietly determined by the results of the first race. The interval between departures is generally 60 seconds, and only the slalom event is used when the beam is not equal. In the race, competitors can glide at speeds of more than 130 km/h.

The vertical height difference between the start and end points of the project varies.

First of all, you need to ** your own movements, and you also need to pay attention to your balance, and the movements must be perfect, and the speed must be fast, so as to be able to reach a certain standard, and there can be foul actions without rock bumps. Thing jujube beating.

The rules of the race are to complete the sliding of the road within the allotted time, and whoever is fast in the middle and who makes fewer mistakes will win the championship.

At Beijing 2022, a total of 307 athletes competed for 11 gold medals in Alpine skiing. Eighty-three countries have qualified for alpine skiing at the Beijing Winter Olympics, and 16 countries have sent only one athlete to the Winter Olympics, and the events they participate in are all alpine skiing.

So the curious baby asked why basically all countries participate in alpine skiing competitions. Think about the main reason.

It's important because it has so many projectsThere are downhill, giant slalom, super-G, slalom, all-around, men's and women's pentathlons, and mixed team events, all of which are collectively referred to as "Alpine skiing".

Downhill: The downhill ratio is the speed. This one is easy to understand.

Super Big Return** slid to the end on a steep slope around the 25-meter-wide flag gate more than 30 bends.

The big back ** around the 10-meter-wide flag gate more than 30 bends to the end.

Back to ** around the flag gate with a relatively small spacing around the 50-70 bends to the end.

All-round: one rappelling slalom.

The requirements for the alpine skiing year course are not very largeGenerally, as long as the mountain is high enough and the temperature is low, it is fine. It is less demanding than ice sports fields and can be built quickly. There is no need to build a U-shaped track.

The climatic and economic conditions of tropical countries limit the training of athletes.

There is also a saying that if any country does not make it to the top 500 in the worldThe Olympic Committee will give you a place in alpine skiing. This is an opportunity for Africa, or for many countries with a small number of athletes competing. (This is a statement that needs to be verified, but it is a very convincing one.)

Because some countries, especially tropical countries, only have 1 athlete to participate).

Alpine skiing has a relatively low barrier to entry for the Winter Olympics, unlike the short track, requires a high level of achievement. The most basic movement of this project is skiing speed, which is also the most basic way to ski. Many small national skiers have lived in Ozhu for a long time, so it is relatively easy to train.

Especially for athletes in countries such as Africa, because of the tropical location, it is difficult to train on the field. In order to allow more countries to participate in the Winter Olympics, the Olympic Committee has lowered the threshold for alpine skiing, and the number of athletes participating is second only to ice hockey's team event.

Alpine skiing has been a sport since the Olympic Games in 1936. Alpine skiing is divided into two categories: speed and technology. At that time, there were only two events: the men's and women's downhill and slalom obstacles.

Since 1952, there have been three fixed events: the giant slalom handicap, the slalom handicap and the sprint down. It has slowly developed into ten competitions now.

At the opening ceremony of the Beijing 2022 Winter Olympics, I found that almost every national team in the competition had signed up for the Alpine Streams event, even if there was only one athlete from that country. There are a few reasons why so many participating countries have signed up for alpine skiing:

1. There are various types of competitions

As a Winter Olympic sport that has existed since 1936, Alpine skiing has been revised and adjusted over the years, and many new events have been added, including many different types of skiing, such as: downhill, super-G, giant slalom, mixed team events and so on. Therefore, it is precisely because of the variety of small events in this category that there are many types of athletes to choose from, so many competitors will choose alpine skiing competitions.

Second, some of these projects have low thresholds

Compared with other skiing and skating events, the level and requirements of alpine skiing will be lower, and it is easier for competitors to participate in the competition. In addition, for some teams in tropical regions, the Winter Olympics will lower the bar due to their limited training conditions, even if the athlete is not in the top 500 in the world, he or she can choose to compete in alpine skiing. <>

3. The requirements for training venues and conditions are not high

The training venues and conditions of alpine skiing are not very high, and there is no need to build a special ice rink or other venues for practice, as long as there are snowy mountains, you can train. For some national teams that do not have sufficient funds, the training conditions and costs are lower than those of other programs, and they can have a longer time and better venues to train. And alpine skiing can be more fast, mastering alpine skiing skills will be faster than mastering skills such as skating and ice hockey, it is more difficult to master balance on the ice, and it is necessary to test stronger racing ability, which is more difficult for some tropical countries, so most of them choose alpine skiing.

Why did every country choose to participate in alpine skiing at the Beijing Winter Olympics? This Olympic Games,Among them, 16 countries sent only one athlete to participate, but they all chose Alpine skiing onlyWhy is that? Let's take a look at some of the unexpected reasons!

One:The entry threshold is low

Unexpectedly, although alpine skiing does not sound like a simple project, it has a low entry threshold. This sport, in which the athlete dives down the slope, is almost a beginner's tutorial for skiing, and it is very common and simple. It's even the basic operation that skiers usually practice.

This has led to many athletes choosing it to compete.

Two:The distribution system of the points competition

There is a limit to the number of places allocated to each country, so how can it be expanded? In any Olympic event, athletes ranked in the top 30 (both men and women) will be allocated an additional quota place for their delegation. If two of them make it to the top 30, or more than one event to the top 30, an additional spot can be awarded.

Ay? And this kind of good thing? Of course, you have to participate in alpine skiing, and if you don't participate in such a simple event, is there a better chance?

Three:The intention of the IOC

Although there are many countries participating in alpine skiing, it is the intention of the IOC to do so. The International Olympic Committee hopes to increase participation and participation in the Winter Olympics through this project. Many countries do not have snow and are from the tropics, and participating in the Winter Olympics is undoubtedly a luxury for them.

The increase in the quota system this time also gives them a lot of hope. Some countries even recruit athletes to participate in the Winter Olympics through the Internet, although it is the lowest threshold event, but it is also a national delegation! This face must be enough!

Although the threshold for alpine skiing is very low, we should give enough respect to our foreign friends, after all, it is not easy for some countries in the tropics to participate in the Winter Olympics.

Because there are many items of alpine skiing, and alpine skiing is a little more spectacle.

Alpine skiing is a snow racing sport in which skis, snowshoes, bindings, and ski poles are used as the main equipment to slide down the mountain and down the course set by the flag gate. Among them, the men's and women's events each have five sub-events: downhill, slalom, giant slalom, super-G and all-around, and the mixed event is a mixed team event. Among them, downhill and super-G are speed events, and the ranking is determined by the result of one run.

Alpine skiing originated in the Alpine region, so it is also called "Alpine skiing". Alpine skiing is a branch of snow sports that is gradually formed on the basis of cross-country skiing. Alpine skiing is thought to have been born in 1907, the year when the first alpine skiing organization, the Alpine Ski Club, was founded.

Since the 20s of the 20th century, alpine skiing competitions have been held in the Alps, and various alpine skiing schools have been established one after another. Alpine skiing has been an Olympic sport since 1936.

The public ski area is less difficult and can be divided into beginner, intermediate and advanced slopes. Ski resorts generally have a few or as many as dozens of slopes to meet the needs of competitions and public fitness and entertainment.

Beginner slopes: The slope is the same as the rolling line (a complete straight line in which a ball rolls down the slope from the top of the mountain to the bottom of the mountain without changing the direction of travel), and the angle of the slope is greater than 135 degrees, the width is greater than 20 meters, and the slope is less than 8 degrees. The stop area of the ski slope must be open and gentle, so that the skiing can basically come to a natural stop.

The "winding" style of beginner pistes is more than 5 meters wide in most sections.

Intermediate slopes: The slope of most sections should be consistent with the tumbling line, the angle of the slope change direction should be greater than 150 degrees, the width should be greater than 25 meters, and the slope should be between 9-25 degrees.

Advanced slopes: The slope of most sections should be consistent with the roll-off line, the angle of the slope change direction should be greater than 160 degrees, the width should be greater than 30 meters, and the slope should be between 16-30 degrees. The narrowest part of the transition course, approach course, and connecting course in the ski course shall not be less than 25 meters.
