Interpretation Of Liu Xiang'S High-Tech Ultra Lightweight Running Shoes

Tonight, the 2012 IAAF Diamond League ShangHai Railway Station.

Will debut.

Every year, Liu Xiang attaches great importance to the performance of this family doorway. This year, ShangHai Railway Station is preparing for the London Olympic Games.

In addition to focusing on achievements, some of the equipment that will be used in London Olympics can be seen in actual combat.

I will give you a comprehensive understanding of Liu Xiang's high-tech equipment, and invite the Xi'an Institute of Physical Sciences, Dr.

A a spare robe.

Sexy pants and shorts

Fans know that after the 2008 Olympic Games, Liu Xiang has been wearing red T vest and shorts.

In order to prepare for the London Olympic Games, Liu Xiang has two sets of robes, one is the split style, the other is the connected style.

Not long ago, in the Japanese Kawasaki arena, Liu Xiang used the latest split style robe for the first time.

According to the introduction, Kawasaki station Liu Xiang originally had two sets of robes for his choice: one is the split tights he used in the competition, and the other is the latest conjoined "land shark skin".

Liu Xiang felt that he was not accustomed to the uniform robe and chose the pair of body tights.

The biggest difference between this set of clothes and before is that shorts become tights. This is not to catch up with fashion, but to reduce wind resistance.

In the past, shorts and trousers were short, but they would be drummed up in high speed games and affected speed. When they became tight pants, they could effectively reduce wind resistance.

According to the researchers who provided the gowns, Liu Xiang's score could be increased by 0.023 seconds in theory.

This rate of increase has been very large at Liu Xiang's level. No wonder Liu Xiang, Trammell and other contestants have been wearing these tights before Oliver.

At yesterday's press conference, Liu Xiang said that this dress was probably the London Olympic game suit.

Interpretation of Gou Gou Bo: compared with

In terms of competition, competition clothing has less impact on athletes.

But the most important thing for a race suit is to see whether the athletes can adapt. This is probably why Liu Xiang chose the split style clothes.

B two robe in reserve

Land shark skin, resistance to power

Liu Xiang did not choose the latest conjoined robe, which was linked by his trousers and his vest, which affected the stretching of his body when hurdling.

But as the latest technology, research shows that in the wind tunnel test, the "conjoined Land Shark Skin" robe can improve the athletic performance by 0.23 seconds.

This is rather amazing data compared to the improvement of the split style robe.

Yesterday, in the news release Hall of the Grand Prix, a member of Xiang's team, who did not want to be named, said that the surface of the land shark was made up of a honeycomb structure similar to that of golf.

The reporter looked at the data of golf honeycomb aerodynamics, and found that honeycomb shaped honeycomb surfaces can change the drag of a honeycomb and turn the head-on airstream into a vortex. These vortices will automatically rotate around the golf balls to create a "boost" effect.

After wearing a shark's body, the human body is close to the circle, and it will also generate vortex swirl after high speed running, so as to achieve the magic effect of "boosting" behind.

The fina has banned the shark skins in swimming competitions, and the IAAF has not yet banned it.

However, many athletes can not adapt themselves to this suit, especially some Asian players.

If ShangHai Railway Station today Liu Xiang wore this shark suit for the first time, he said he would like to try the magic power of this new equipment. If the result is good, then Liu Xiang will also be able to compete in a shark suit.

Interpretation of Gao Gou Bo: the high-tech robe is more important to athletes in psychological suggestion.

Because Liu Xiang and his competitors are top players in the world, they also have special designers to do research and development for them. Their technological content of their robes will not be lower than that of Liu Xiang.

Liu Xiang used a new robe to make himself feel inferior to others at least.

C special running shoes

The shoes are light as socks, and the fiber thread is 2 microns.

In 2008 Beijing Olympic Games, Liu Xiang had a running shoe weighing 214 grams.

In February this year, Liu Xiang's running shoes for the London Olympic Games have been published. Designers say that Liu Xiang's new running shoes are light, like wearing a pair of socks.

According to the data measured by biomechanics experts, the weight of running shoes increases by 100 grams per hour, and the physical energy consumption increases by 1%. Therefore, the lighter the running shoes are, the better the quality of running shoes is.

This is like a car in order to reduce fuel consumption, the use of lightweight, streamlined design.

The characteristic of Liu Xiang is that the advantage of the second half is obvious, the lighter the running shoes, the more energetic the second half is, the greater the improvement of the result.

Reducing weight means that the material is more frivolous. The upper surface of Liu Xiang's running shoes is made up of a special fine fiber which is less than 2 microns in thickness.

There are 7 spikes for running shoes. In order to lighten the weight, Liu Xiang's shoe spikes have been reduced to 5 in 2008.

The soles are more exquisite. Liu Xiang belongs to the explosive athletes.

It should be light enough and hard enough. The sole of the foot is a special carbon fiber baseplate. The heel is cushioning special colloidal material.

Interpretation of "Gou Po": as sprinter, the lighter the running shoes are, the better the average running shoes are, and as far as I know, less than 300 grams of running shoes.

But Liu Xiang's running shoes are made according to his own feet size. We usually choose the most suitable ones according to the fixed shoe code label.

D running shoes components

Anti slip device, right shoe sole thickened.

In order to prevent foot slip effectively, Liu Xiang has special devices in his running shoes.

When people walk or run in shoes, every step will appear at least one millimeter of lateral slip of their feet, usually not felt, but the gap is obvious.

Reporters repeatedly watched the video of Liu Xiang's competition. Statistics showed that Liu Xiang had to take 40 steps to complete the 110 metre hurdle. If there was no lateral anti slip device, the 40 millimeter lateral difference would be accumulated. In the modern sports world, the time needed to shorten the sprint time to 1/1000 seconds or 0.01 seconds would be shortened by the high technology cost. Of course, we should avoid these useless work.

Besides, the structure of Liu Xiang's left and right shoes is different.

For the injured right foot, the designer added the thickness of the foam cotton to the heel of the right shoe and locked the ankle. At the same time, the shoe size changed from 42.5 yards to 43 yards.

If we watch carefully tonight, we will find that Liu Xiang's shoes are different from other players: his running shoes still keep the buckle with the shoelace function.

This hasp is actually helping Liu Xiang make the final preparations before the game - the shoelace is tied up and the studs are not loaded. These hints help him to concentrate on the game.

Interpretation of Gou Gou wave: in addition to high-tech materials, the real high-tech of Liu Xiang's running shoes is reflected in his special tailoring process.

First, make a foot mold for Liu Xiang. Then, according to the characteristics of Liu Xiang's foot force, a database is set up in the computer. According to these data, different materials are applied to the upper and sole to suit Liu Xiang's feet.

E mysterious ointment

It's hard for ordinary people to use oil to keep their body temperature.

Liu Xiang has recently uncovered another secret weapon, which is an ointment applied to the body before the warm-up.

Coach Sun Haiping said: "this ointment can be applied to the skin after warming up to maintain body temperature.

If you encounter low temperatures, this is a good preventive measure. "

London's climate has been abnormal this year. It has been heavy rain and low temperature for nearly two months.

The ointment used by Liu Xiang is similar to that of hot pot. The surface does not look hot, but the heat is sealed by a layer of grease in the soup.

Just like the thermal insulation film, Liu Xiang uses ointment as if he is applying a warm underwear for himself.

It is fair to say that athletes wear warm clothes before the game. Is the ointment used to do the same thing? Sun Haiping explained: "the Olympic Games will be checked from the roll call to the game for at least half an hour. If the temperature is very low, the muscles will drop in temperature and the muscle viscosity will increase, so the warm-up in front will be done."

Little is known about what this ointment is.

Liu Tie, an expert in physical education at the Provincial Institute of physical education, told reporters: "I think it should have been invented by an American scientist. After applying this ointment, the body can not only get fever, but also heat the muscles.

It is said that it is very expensive, and athletes generally can not afford it.

The temperature difference between Shanghai day and night is bigger. Liu Xiang seems to have applied this mysterious ointment tonight.

In fact, it is not uncommon to apply ointment before competition.

Amateur competitions, athletes before the application of safflower oil, is to make the body warm up.

Painting itself is the process of rubbing the skin and making the body hot.

Ointments are divided into two categories: Water-borne ointment and oily ointment. The amount of ointment used by Liu Xiang is higher.

F change hairstyle

Can you run faster before a short haircut?

In order to make Liu Xiang run faster, there are many enthusiastic people in the market, such as not to go back when sprint, because the distraction will distract attention.

The scientific analysis of this analysis can not be implemented, but many people want Liu Xiang to cut his hair short or simply shave his head to reduce windage.

Liu Xiang coach Sun Haiping said recently that many people around him had told him to suggest that Liu Xiang shave his hair short.

However, to what extent can the length of hair affect performance? No scientific data are available.

However, at a press conference yesterday, Liu Xiang appeared with a short haircut close to the head, which may indicate that he is already 29 years old and is trying to improve his speed as much as possible.

Interpretation of Gou Gou wave: as long as the hair is not too long, it has no effect on sports performance.

If not mistaken, Liu Xiang shaved his hair before the 2008 Olympic Games, but his foot hurt him out of the race halfway.

It is Robles who wears a gold chain around his neck to pick the crown easily.

Actually, hairdressing is still a bigger psychological factor.

Liu Xiang: now in good condition in 2008.

Don't miss the "appetizers" at ShangHai Railway Station: Men 100 meters Su bin challenge Powell.

Tonight, the 2012 IAAF Diamond League ShangHai Railway Station, the 110 meter hurdles competition gathered, but Liu Xiang is still the biggest attraction.

In addition to Robles's absence and Trammell's retirement from the tournament, ShangHai Railway Station almost gathered the top 110 meters hurdles in the world, and all came from the United States, such as Oliver, Merritt, Richardson, and temporary replacement of FOK, which was played by Trammell.

Oliver's best result is 12 seconds 89, and Merritt is the creator of the world's best 13 seconds 03 this year.

This brings Liu Xiang to the United States tonight.

Yesterday, Liu Xiang said that his current state is definitely better than in 2008, and a high level opponent can stimulate him to do his best. "If every race has many athletes with a level of about 13 seconds, then in this competition, the final result will be better, which is what the audience wants to see."

In addition to Liu Xiang, there is another point in the ShangHai Railway Station tonight, that is, the 100 metre flying man.

Su Bingtian, who recently ran out of 10 seconds and 04 seconds at the Kawasaki station in Japan, will challenge Jamaica trapeze Powell.
