Why can the blades and the back of the sole of speed skating skates be separated?

This is called a dislocated knife.

It is limited to speed skating.

The first speed skater did not dislocate.

It's a little different than short track speed skating.

But in the 1990s, a Dutchman named Neuskonen sparked a skate revolution.

He invented the paper towel skate machine.

Now dislocate the knife and use the knife position when the athlete starts to step on the ice to return to the knife seat when he ends to step on the ice to increase the distance of the athlete's step on the ice.

Meanwhile, traditional skates use the strength of the athlete's knee and hip muscles.

Kleip skates can use the strength of the athlete's ankle joint on this basis, so everything.

Speed ??skaters also use the strength of their ankle joints to perform a toe-pointing motion after a normal kick.

The purpose is to separate the knife from the knife base, thereby increasing the distance of the kicking ice.

Goal 2.

Avoid the influence of the blade tip on the speed of the ice during normal skating.

Its advantage is to save athletes' physical consumption, while increasing the range of motion, making the motion look more stretched and faster.

It was confirmed that before the Higashino Olympics, all athletes wearing Claypool skates could increase their speed by more than one second in a 400-meter lap.

In addition, he does not use short track speed skating, because short track speed skating has a small venue, short straight turns, and uses large-scale pedal ice, so it may not work, while short track speed skating mostly uses card tactical techniques.

More importantly, the dislocation knife does not slip easily when bent.

The main road is a curve.

It is better to use the centrifugal force of the bent pipe to accelerate.

So, all basic speed skaters talk about bending technique better on the main roads than the short track.

The above are some of my views on speed skaters over the past ten years. They are not enough. Please add more!

There is a documentary about the technical content of sports products that mentions this.

Traditional skates are fixed and it is difficult for athletes to improve their performance at a certain stage.

Scientists, dynamic image capture, computer-aided design and other research believe that using split skates can improve the efficiency of XXXX Bashan, and then everyone will use it.

Does the answer look like water?

But in fact, this change involves more than just a pat on the head.

I remember in the documentary, this change took into account aerodynamic resistance, ice surface friction accumulation, the rationality of athletes' body energy conservation, etc. It is basically a revolutionary product, like shark skin.

By the way, this leather is a revolutionary product.

At least 10 years.
