Speed ​​skating equipment Raiders: choose skate skate experience speed mania

The 2022 Olympic Winter Games will come to China with pure white ice and fast speeds (according to the authority's test data, the speed of excellent speed skaters can reach 60km/hr or more). Is it possible for you to yearn for yourself? Galloping on the ice, experiencing the madness of speed?

Just like snowboarding, snowboarding and football playing, if you want to participate in speed skating, you also need to have speed skate special equipment – ​​ice skates. So there is no basis for beginners, there are certain basic amateurs or long-term. Professional athletes engaged in training need to choose a pair of ice skates that suits themselves according to their own conditions and project characteristics. The ice skate that we often say is actually the collective name of the two parts of the skate and the knife. For the participants with different foundations and different purposes, they should be treated differently.

skates:

From the material point of view, the speed skating skates are mainly made of leather, glass fiber and carbon fiber. With the development of science and technology, leather skates gradually withdraw from the stage of history, and are used as accessories for other materials. Now, the market is based on Glass- and carbon-fiber-based skates. The performance and price of these two materials are very different. The glass fiber skates are relatively soft and have poor hardness. They do not support or protect the ankle joints. After prolonged use, the shape is easy to change and cannot be restored. The biggest advantage of the material is that it is cheap and suitable for enthusiasts who want to try speed skating and don't want to have too much financial investment, or for occasional exercise. The hardness of skates made of carbon fiber is large, the shape can be maintained for a long time, and the shape can be moderately changed by means of heating, etc. The shape after cooling is fixed at room temperature or in a cold environment, but it is not easy to change, but the price of carbon fiber skates is relatively high. At present, even the cheapest carbon fiber skates on the market, the price must be more than 1,000 yuan.

From the upper point of view, although speed skating and short track speed skating are all on ice racing projects, there is still a big difference between the two in terms of equipment. In terms of the upper height of the skates, the speed skating skates lower and better The guarantee of the flexibility of the ankle joint; and short-rate skates higher upper shoes, support better, but less flexible, which is related to the special characteristics of the two projects. The short track speed skating site is small, the radius of the curve is small, and the centrifugal force during the gliding process is large. In order to ensure that the curve gliding at a high speed, a larger tilting angle is required when the curve gliding, so the stability of the ankle joint is required to be high. The speed skating site is larger, the radius of the curve is large, and there is no short track speed skating curve. The centrifugal force is large, but the straight is longer. The skating person needs a more flexible movement center of gravity to ensure the gliding speed of the straight section. Therefore, in the selection of skates, everyone can base on their own basis, the specific strength of ankle joints and site conditions.

From the point of view of the production process, the speed skating skates are the same as the running shoes and the cycling shoes of the bicycle. In order to ensure the comfort of the foot and the good sports effect during the sports process of the professional athletes, the skaters are provided with customization for the needy people. Foot shoes. However, the higher cost of the foot-type shoes, whether domestic or foreign speed-skating foot shoes, the price is a few thousand dollars high is a few million, the expensive price makes it not suitable for popularization and promotion. The vast majority of skates are divided into common-model skates. The popular-model skates are the same as ordinary sports shoes. They are mass-produced skates classified according to the shoe number. Such skates do not require high production technology, so the price of the product is not high. Also relatively low. The foot shoes are different, just as each person's fingerprints are different, and each person's foot is also very different. The production of excellent foot-shaped shoes is almost all hand-made, and each part of the production model, mold casting and production is a delicate manual operation. Such skates can provide good wrapping and comfort for the foot, and also improve the exercise. effect. However, if the wearing of the skate is not comfortable, it will feel the phenomenon of pinching feet, grinding feet, which will seriously affect the pleasure during the movement, and if the package is poor, the foot may produce relative movement in the shoes , This will break down the ice power, affect the ice effect, and more importantly, if you wear such skates for a long time, it will lead to acute or chronic sports injuries. Therefore, professional athletes or conditional speed skating enthusiasts will choose foot shoes.

Knife tube:

With the 1998 Nagano Japan 18th Winter Olympics as the demarcation point, the development of science and technology has produced a new leap in speed skating. The reason is the formal use of the new CLAP ice skate. The traditional knife tube is called by the industry as a dead knife, that is, the knife body is a fixed one. The new CLAP ice skates are called dislocation skates, in which the front knife holder of the ice skates forms a hinged connection with the skates, and the back knife holder and the skates can be separated. When the skater pushes the ice center of gravity forward, the rear knife holder can be separated from the skates automatically, avoiding the "dead knife" tip friction sliding surface to increase the sliding resistance, thus extending the ice clearance distance and optimizing the structure of the ice movement. Strengthen the ice effect and increase the speed of taxiing. Although the CLAP dislocation skates are very helpful for professional athletes, it is not suitable for all people. Beginners or children are still trying to choose the old-fashioned dead ice skates when they first started learning speed skating. It is relatively stable and the new type of clap skates , The station under the feet is unstable, and it is easier to fall and stand unsteadily. And even if the death knife is also divided into speed skating knife and short knife, the primary, the knife should not be wrong, speed skating knife is lower and more stable, short knife high, poor stability. The contact speed skating sport should start with a dead knife, and the calp skates may cause ice afterwards. In the early days, wearing a dead knife can cultivate the right technique and benefit the future development of technology. The death ice skate can change the ice effect and improve the ice. It is especially noticeable in the curve taxiing. Knife tube, you can choose the primary skate. In terms of quality, there is little difference between the death knives, and the quality of domestic ice skates, especially dislocation type skates, is relatively poor, but the price is low. The main difference is between the domestic and imported products of dislocation skates, and the quality of imported dislocation type skates is obviously superior. In domestic skates, both the steel used in the knife tube and the endurance of the hinge have good performance, but imported skates are expensive and suitable for amateurs and professional athletes who need to improve their performance.

For beginners or children, due to the lack of specialized training, the strength of the ankle joints is insufficient. In the skates, the upper is not easy to be too low, not easy to be too soft, and the upper is too low or too soft for children to stand still. Even if it stops, it can easily cause ankle joints. The varus or valgus, if the ankle joint strength is poor, still need to rely on the knee joint strength compensation, the knee joint will appear external or partial deviation, long time gliding for the growing child, the presence of lead K Type, type X, and type O legs. In addition, due to the long production cycle of foot-type skates (the production cycle of a pair of high-quality speed-skating foot shoes should be at least 3 months, the carbon fiber epoxy resin layer needs at least 4 layers or more, and each layer needs to be completely cured. After the next process, the child grows faster, the foot becomes longer during the production of the foot shoe and the finished product, and the foot shoe is smaller than the foot when it is finished, so it is best for children to choose the skate. In accordance with the number or actually try on mould shoes. Choosing the death knife in the choice of the knife tube is not only safer, but also more conducive to the cultivation of the correct technology and laying a good foundation.

There are certain basic lovers who can choose skates and knives based on their own characteristics and economic ability. However, regardless of the type of people engaged in speed skating, the criteria for choosing skates should be comfortable, skates on the ankle. Poor package, large gaps between the upper and the ankle, may cause lack of concentrated ice, support instability, that is, stability is not good, but also easily lead to knife bias, stand up the knife. If gliding technology and economic conditions allow, foot shoes and imported CLAP skates can be selected.

The ice skates of professional skaters of speed skating are like sniper's guns. They attach great importance to every small part. Skates and knife tubes are carefully selected and fixed after a period of running-in. If there is no equipment damage or technical changes, they rarely replace the skates. Most skaters of professional athletes now have foot-type shoes. The manufacturers of foot-type shoes will also appropriately adjust the details of the skates according to the characteristics of the athletes, such as the hardness and height of the upper. In terms of blade management, most athletes with short-distance strength will choose MAPLE knives, while medium- and long-distance rhythms will use VIKING knives. Internationally, the brands of speed skating skates include Dutch Maple, Viking, 4G, and Marchese in the United States. In addition, some skaters of Korean brands in recent years have also been recognized by some athletes. Domestic ice skates are best known for their black dragon skates and have the longest history.
