Is there a difference between speed skating, figure skating, curling, and ice hockey?

There is definitely a difference, no matter how well the ice rink is decorated, in the end the ice surface will still be cut and dented, and it will become dirty and flawed, thus losing its luster. Whether the ice can be repainted quickly and effectively is just as important to ice skating as it is the first time it is formed. Before the advent of ice resurfacing machines, the ice on the ice rink was used by workers with shovels.

Hand-laid with towels, hoses and rubber brushes, resurfacing a standard-sized ice hockey rink is a time-consuming and laborious task.

Curling. It is in a specific position, slightly lower in the middle, with ice crystal particles on the surface. It is easy to arc, increases friction, and requires humidity. Figure skating.

and short track always use the same venue. First, the size is the same, and the short track only needs to be placed with a corner marker. Second, there is no conflict in the alternate time of the game, which is convenient for the centralized use of the venue. We just need to adjust the ice surface in the middle. Pyeongchang.

It takes four hours to adjust the ice surface in the short course of the Winter Olympics in the morning and evening. This is uncommon and is usually one project a day.

Speed skating has a smooth surface, the harder ice surface is better than the other ice surface, the hard and crisp ice surface helps to speed up, the ice-making temperature needs to be minus 6 to 7 degrees, and the harder ice surface provides better support for the long blade. Speed skating.

It is divided into short track and main track. The length of the circle varies with the magnitude of the field. The water that spilled on the ice truck was boiling water.

When boiling water is poured on the ice, it can better blend with the old ice, the water is purified, and it can even be drunk directly, which greatly guarantees the quality of the ice road. Even if the race is empty, the ice car pours the ice every two hours or so. This is because after about two hours, the ice will freeze and it will no longer be suitable for racing.

Figure skating is also smooth, but the ice surface needs to be soft to ensure the take-off movement, and the ice temperature required for figure skating is about -3 to 4 degrees Celsius. Figure skating and short track speed skating.

Generally speaking, the same ice rink is shared, but it is rare for a short track event like Pyeongchang to run out in the morning and continue to use it in the afternoon, so for different competitions, the ice surface needs to be maintained after the competition every time.

The difference is not particularly large, the ice surface is relatively flat, but the bottom layer and temperature are completely different. The rules of the competition are also completely different, the overall requirements for the athletes are different, and then speed skating requires skates and skates.

The ice surface needs to be relatively hard in speed skating, and the ice surface can be slightly softer in figure skating, but the quality requirements are relatively high. When playing ice hockey, the ice surface can be slightly worse than figure skating. When playing curling, there must be some small particles on the surface of the ice.

The difference is very big, the requirements of the sports are different, the requirements for the athletes are different, the difficulty of the movements is different, the scoring criteria for the competition are different, and the standards for the posture and the beauty of the movements are also different.

There is a difference, the temperature of the bottom layer is different, the required site is not passable, the hardness is different, the smoothness is different, and the thickness is different.

There are differences in the temperature of the bottom layer, the lack of the required site, the difference in hardness, the difference in smoothness, and the difference in thickness.

First, the characteristics of ice blades.

Figure skating skates have knife teeth at the front end, and the knife teeth are mainly used by athletes in the process of jumping, and are not used in sliding and spinning. Ice dancing has a shorter blade back than other disciplines, which is to meet the requirements of the duo dance for close cooperation and fine footwork.

Second, the help of ice skates to the game.

In the figure skating competition, the blade of the ice blade is very thin, therefore, even if a lot of pressure is generated on the ice surface when skating, the melting point of the ice is reduced, and the ice in contact with the ice blade melts into water, which is conducive to the sliding of the skate, according to the ice action and the shape of the ruler and the body, it can be divided into free figure skate prescribed figure skate ice dance figure skate, because the figure skating movement is mainly based on jumping and rotating steps, so the difference with other skates is the front knife teeth, to ensure that the skate blade is tilted forward 10 degrees, Allow the bottom tooth to touch the ice. The blade is at the back, the blade is short, and the blade arc is large, which is more conducive to athletes to perform various jumping and spinning movements on the ice without slipping.

This is the ice skate worn by athletes, generally the flexibility is better, more stable, the configuration is relatively high, the speed is relatively fast in the process of driving, and the blade is relatively short, the arc is obviously more flexible, which can improve the speed of the game, can obtain better results, and can ensure the stability and safety of athletes.

The length of the skate blades used in figure skating is slightly longer than that of ice hockey players, but there are a few ice teeth at the front that help the athlete jump and spin, increase friction with the ice surface, and make it easier to stop. Ice hockey players have higher skate shoes and boots, which absorb some of the force in their calves and less stress on their ankles, making it easier to stand and slide.

What is so special about ice hockey players' skates?

A good pair of ice hockey shoes should not only be lightweight, comfortable, but also safe. In terms of materials, ice hockey shoes should be hard, strong, and elastic from shoe to knife, able to cushion and release impact, preventing foot injuries when hit. In recent years, as the scientific and technological content of hockey sticks is getting higher and higher, the ball is getting harder and harder, hockey shoes and protective equipment are becoming more and more "standing on the wings of science and technology", and "contradictions and conflicts" have improved the development level of engineering equipment.

What materials are ice hockey shoes made of?

The body of an ice hockey shoe is typically made up of hard plastic, carbon fiber, padding, and leather goods, with a focus on protecting the athlete's ankle and providing it with the necessary support. Depending on personal preference and technical characteristics, it is also possible to choose a base with different groove depths. Deep grooves are suitable for players who value flexibility, and shallow grooves are suitable for speed players.

In addition, professional players make temporary adjustments before the race based on their weight and technical characteristics, and even according to the hardness of the ice surface on the field. <>

Do figure skating skates need to be sharpened?

Of course, figure skating requires a cutting edge. Generally, it is the end of the operation. Because the blade is very blunt in that place, it is difficult to glide on the ice.

Wrestling and even sprains can easily happen. So skates are usually sharp. Ice blade grooving is divided into flat edge and grooved edge.

Beginners can flatten the blade and are more suitable for speed skating. The grooved edges have a strong grip and are suitable for figure skating. According to the thickness of the blade, the flower knife is the thickest and the running knife is the thinnest.

The reason for the cutting edge is that when skating, a lot of pressure is generated on the surface of the ice, which greatly reduces the melting point of the ice. The ice that the blade touches melts into water, which reduces the friction between the ice blade and the ice, and is more conducive to skates gliding on the ice surface. <

These two types of skates are completely different. To put it simply, the skates we see can be divided into three categories, the first is the skates used by speed skaters and short track speed skaters, commonly known as racing knives. <>

The second type is knives used by ice hockey players, and the blade competition knife is shorter, commonly known as ball knife.

The third category is the skates, which are used by figure skaters and competition staff of all kinds, with the shortest but very flexible blades. <>

From another angle. The short program is the equivalent of a preliminary or section exam, brushing off some of the bottom runners at the top competitions (such as the World Championships and Winter Olympics) and leaving only the 24 men in front of them to continue the free skate. There are so many people participating in the top competitions that the spectators and judges are tired of competing all the free skates.

Also because it is the first test, there will be some hard rules and requirements to measure whether the basic skills of the contestants are up to standard (for example, the women's singles short program can not have a quadruple jump, there must be a bow turn, there must be a A jump, and the short program of the youth group has a prescribed jumping action every year), the short program is short and capable, there are not many technical movements, and there is an upper limit on the difficulty and score value.

The free skating is equivalent to the re-examination or the term test, the duration is longer, the technical action is more, the difficulty is not limited, you can choreograph according to the movements you are good at to strengthen the score advantage, and the content that can be choreographed and expressed is more colorful, so that the contestants' program is more personal style and full and unique. Because the score is almost twice that of the short program, it accounts for a greater proportion in the final score tiebreaker, and the score disadvantage of the early short program can be counterattacked by the extraordinary performance of the free skate.

Ice hockey has different requirements for skating, but it also has requirements for internal and external edges, and the requirements for skating speed, flexibility and explosive power are also different. The ice hockey skating requirements are to match the player's flexibility in controlling the ball, passing and receiving the ball on the court, and it is difficult to improve without a good skating foundation, and there is no way to play the skills on the hand on the pole.

Figure skating has strict footwork requirements. Every skating action has a standard under the feet. The handling requirements for the internal and external blades are very strict, and there are also strict requirements for the posture of the body.

Skating is the most important thing in figure skating, but figure skating is not only about the feet, but also about the coordination and beauty of the whole body.

The surface looks different, the thickness of the blade is different, the length of the blade is different, the ice blade of figure skating has a tooth in front, while the ice blade of the ice hockey bean orchard does not have it, and the height of the shoe is different.

Figure skating skates have protruding serrations in front of their blades and have a short body and a smooth blade for easy rotation, whereas ice hockey players have no serrations and the blades are smooth arcs for advancement.

The biggest difference between short track speed skating and figure skating is that figure skating has two blades for stabilization, while short track speed skating has only one blade for speed. There are currently three types of skates on the market. One is a running knife for professional athletes, one is a figure knife for ordinary people and figure skaters, and the other is a knife specifically for ice hockey and curling.

Short track speed skaters generally choose running skates in order to pursue the speed limit and the durability of skates. Figure skating is a sport that focuses on performing skills on the ice and requires more stability than other sports.

The most important thing is that the competition is different: short track speed skating is a direct competition between competitors, and the first to cross the finish line wins; Speed skating is compared to the fastest and highest-ranked athletes. In other words, short track speed skating is like running in athletics, while speed skating is more like long jump.

Second, short track speed skaters have larger ankles than speed skaters. Short track speed skating and speed skating are connected differently to ice skates. Short track skates are fixed to the shoe, speed skates are mobile, and the back half is not fixed under the skate.

As we all know, short track speed skating is a sport in which a group of athletes have to run an oval track within a set amount of time.

In this case, it is crucial for the athlete to choose how to win with the skates under their feet. Sturdy skates with little friction with the ground can quickly improve the athleticism of short track speed skaters. Help them run faster and get better results.

Short track speed skating, the competition venue is only 30 to 60 meters, and the length of each lap of the track is meters. Short track speed skating originated in Canada in the 80s of the 20th century. At that time, some speed skaters in Canada often went to indoor skating rinks to practice, and with it came indoor speed skating competitions.

At the beginning of the 20th century, such competitions were gradually widely held in Europe and the United States. It was included in the 1992 Winter Olympics. Figure skating is usually performed by two athletes, and the judges score the skaters based on their different performances.

Therefore, figure skating skates will pay more attention to stability, and whether the contestants can perform consistently or well is the focus of many judges. So the skates for figure skating are thicker than the skates for short track speed skating, and there are strict rules for the spacing between the skates.

Figure skating skates focus more on the many forms they can make, while speed skaters' skates focus more on how fast they can tolerate.

Speed skating blades, referred to as speed skating knives, can be divided into short track speed skating knives and large runway speed skating knives. Speed skating blades are suitable for long-distance skating, so speed skating blades are generally made of alloy materials with good slip, wear resistance and moderate hardness, and figure skates are mainly suitable for figure skating. Since most of the players mainly jump and spin, the blade of the figure skate is curved.

What is special is that the figure skate has serrations in the front and a groove in the middle, which makes it easier to rotate. The pattern knife is tall and short, making it easy to stand on; Speed skating knives are short and long, making them difficult to stand on. The speed skating blade body is very long, the blade is narrow and flat, the figure skate blade body is short, the blade is wide and has a curvature, the speed skating blade is fast in a straight line, the arc is large, and the turning is inconvenient; Pattern knives are more convenient to turn, but they are not suitable for walking in straight lines.

The ice on the figure skating rink of the Winter Olympics is different from ordinary ice, and the ice is made by using carbon dioxide, the most advanced production method in the world, to make the ice tougher and smoother.

Figure skating is a sport that combines skating and dance until 1924, when it was held at the Capital Indoor Stadium in Beijing.

The Capital Indoor Stadium is the first indoor ice arena in China, which has undergone a large-scale renovation and expansion to meet the needs of the Winter Olympics, inheriting the concept of green technology, and adding ice-making functions in addition to the original facilities. The ice rink in the hall can be converted to meet the needs of the competition, and the ice rink is made using the most advanced carbon dioxide ice technology in the world.

The use of carbon dioxide technology is the world's most advanced, environmentally friendly technology, the use of this way to make the ice temperature difference will not exceed the degree of ice, at the same time the environmental protection of heat utilization is also very high, the ice generated by the waste heat reuse, according to statistics can save more than one million kilowatt-hours of electricity per year, fully embodies the environmental protection green. This ice-making method is more uniform than the traditional ice-making method, and can also improve energy saving by 30%, avoid the situation that the temperature of each part of the traditional ice-making is different, and can be faster and more effective for site conversion.

The Capital Gymnasium will quickly replace the two sports on the same day, and the skates on the feet will draw various shapes on the ice surface when the figure skaters make many difficult movements, so the temperature of the ice making should reach minus three to four degrees Celsius. The ice-making temperature of short track speed skating will be minus 6 to 7 degrees Celsius, and only harder ice can play a better role in supporting the strength, which fully demonstrates that China's ice-making technology can be ahead of the world level.

International events such as the Winter Olympics use different ice-making methods than regular ice-making, with different levels of temperature and ice hardness. In order to better reflect the excitement of the Winter Olympics, the Capital Indoor Stadium adopts the latest sound and light technology, and at the same time uses environmental protection and advanced ice-making methods to create a "most beautiful green ice".
