The reason for Liu Xiang's success is not only his extraordinary athletic talent, but also a factor that can not be ignored.

　　秘密武器1：“金色魔鞋”

Liu Xiang's shoes are highly technical.

At present, the shoes worn by Liu Xiang are known as "golden shoes". The shoe upper of this kind of running shoes has a special piercing design, and the "locking" system is used at the tip of the shoe. There are 5 convertible spikes on the elastic floor, which are both comfortable and comfortable. That is, the shoes accompany the Oriental flying man Liu Xiang to create a world record of 12 seconds 88.

In track and field rules, there are strict rules for the number, length and diameter of running shoes, but there is no restriction on the location of shoes and the weight of shoes.

Therefore, choosing the location and shape of the spikes reasonably and lighten the weight of running shoes has become a research topic.

At present, the spikes of running shoes are mostly changed from sharp ends to flat heads, and the sole is changed from the plane to the crisscross ridges. The purpose is to increase the friction between the sole and the plastic runway, and reduce the resistance when the feet are off the ground.

Some running shoes also change the shape of the ends of the forefoot left on the ground, and install a few small nails to increase the ground effect of big feet.

In addition, according to the data measured by biomechanics experts, the weight of running shoes increases by 100 grams, and the physical energy consumption increases by 1%. Therefore, under the premise of ensuring the quality, the lighter the running shoes are, the better.

　　劉翔奧運跑鞋“ZOOM SUPERFLY G5”簡介

Liu Xiang's current running shoes are the "ZOOM SUPERFLY G5" designed by Nike for strength sprinters. They have three styles: red, white and gold.

Liu Xiang wore the white section in the men's 110 meter hurdles final of the Athens Olympic Games.

It was lighter than Michael Johnson's famous "golden running shoes" at the Sydney Olympics.

Key technologies:

(1) the front leg band frame design provides a comprehensive locking foot function while achieving maximum power pmission.

(2) light weight, wedge type Phylon middle sole keeps light shoes.

Low floor design near the ground provides protection against impact.

(3) flexible Pedax nylon trailer, and the linked front palms provide protection for rotation during movement.

(4) 5 detachable spikes provide stronger grip in the main grabbing area.

Li Ting looked at Liu Xiang's performance in this way. "Breaking the world record is a concentrated expression of many external conditions and internal factors. For example, in Athens, Liu Xiang ran 12 seconds 91 in the adverse wind 1.1 m / sec, and 12 seconds 88 in Lausanne, the wind speed was 0.6 meters below the wind, and the wind speed was 1.7 meters / sec. In theory Liu Xiang ran better in Athens, but the result was not the conversion of wind speed."

Hurdles and hurdles are divided into front leg, hind leg and thigh muscle.

The first two have the greatest impact on performance.

Liu Xiang's hurdle on the eighth hurdle has little effect on his speed.

Seldom had he seen such a situation before.

(video shows that from third to seventh hurdles, Liu Xiang's rhythm is well controlled. He is also the fastest person at this stage, proving that he has a high quality of training.

It may be related to the high fever, column training and physical impairment in Osaka the previous week.

Liu Xiang broke the world record second times at the time of the road. This is the ninth way. All of them are on the side. Therefore, the influence of the road is far from the key factor, after all, it is straight road.

What really affects your performance is the players around you.

At the Athens Olympic Games, duoki was hurdling for the same speed as Liu Xiang in the latter half, and finally missed the third place. But the Lausanne Grand Prix was only following Arnold's catch up, and Liu Xiang set the world record.

In addition, the collision should also be vigilant, because this will mean a loss of 0.03 seconds and a winner.

In 2005, dooki met Johnson in the finals, making the latter third.

The starting phase of starting is not just the moment of starting off the starting blocks, but the third hurdles from the starting blocks.

From the start to the third hurdle, it will be difficult for Liu Xiang to reach the top three in the future. (Liu Xiang starts at 0 seconds 161 and occupies sixth in all players), but this link will not be an obstacle for him to break the world record again.

Moreover, his skills from third to seventh are too good, and with columns, the characteristics of Asians are fine.

Secret weapon 2: "Xiangqi team"

Behind Liu Xiang is a research team composed of five or six people, who specialize in scientific research for Liu Xiang. Liu Xiang is affectionately known as the "Xiang team".

Xiang Zhi team members: Feng Shuyong (deputy director of Tian Guan Center), Li Ting (senior laboratory technician of the General Administration Research Institute), Qian Feng Lei (Shanghai Xhenzhuang base), Xu Yicheng (Shanghai Sports Science Research Institute), Li Aidong, Yuan Tinggang (general body Institute).

This "Xiang team" usually goes to work while Liu Xiang is sleeping, analyzes the data of Liu Xiang's training and competition, and analyzes the situation of Liu Xiang's opponents, so as to know her and know her, and fight all the battles.

It is not for decades to serve genius.

In order to prepare for the 2002 Asian Games, the China Track and field association established a scientific research team of the Asian Games. In 2003, the world championships in athletics, Liu Xiang won the bronze medal. From that time, the scientific research team of Liu Xiang was formally established, and the group was affectionately known as the "Xiang team".

Liu Xiang's research team was wearing sports T-shirts, sports shoes and a bright smile. Their image completely broke the image of researchers wearing high gowns and white gowns.

The daily work of the scientific research group is to take Liu Xiang's daily training and competition with the home DV machine, and bring the picture into the computer, analyze and study Liu Xiang's technical action, so as to get the data of hurdle angle and hurdle cycle of Liu Xiang, and then hand it to Sun Haiping coach to hold Liu Xiang's state.

After Liu Xiang's training in the morning, the scientific research team began to analyze computers without stopping.

When the final result was carved into a CD, Liu Xiang was taking a nap in his room.

In the afternoon, Sun Haiping can get the latest information from Liu Xiang.

If it is afternoon training, the scientific research team will work overtime in the evening, and second days early in the morning, the CD-ROM can be sent to Sun Haiping's hands.

Li Ting, the head of the scientific research group, said that Liu Xiang had run 12 seconds and 90 seconds in the last training session before leaving Athens. But by analyzing the data of Sun Haiping and researchers, we came to the conclusion that the climax was too early.

Determined to add weight training to Liu Xiang before cooling off, so as to ensure that Liu Xiang will best state to the Olympic finals.

Li Ting said, if competitive sports is a war without smoke, then coach Sun Haiping is commanding officer, Liu Xiang is commando, and our scientific research team is the staff headquarters, that is, gathering intelligence, grasping the situation of enemy and ourselves, and then providing reference advice to the commanders, so as to formulate operational plans.

Scientific research is actually the support and guarantee of athletes and coaches.

The work of the scientific research group is to record and collect the situation that the coaches can't see and feel, that is to use the instrument to observe the state of the athletes, and to collect the relevant data, which is called the technical diagnosis.

We have to collect relevant information in competitions and intensive training courses. At least two times a week, the intensive training research team must be present.

Li Ting said, "when Liu Xiang moves from the general level to the world's top players, we have been testing, and each competition should be compared with the performance of hurdling Prince Alan Johnson.

At the Athens Olympic Games, the second round of the 110 meter hurdle preliminaries, Alan Johnson accidentally fell down. We then noticed that Du Kulei ran 13 seconds 06 in the third round, which is equivalent to the best result before Liu Xiang.

Through analysis and data comparison, we find that the net running ability of Du Kore is amazing.

Through video analysis and data comparison in front, we also found that when he was in the lead, he had a great advantage. If he was in a backward pursuit, he would be in a turmoil.

In addition, Du Chu Lei ran out of his best personal results in the first three shots. We doubt whether he will be in the best position again in the finals, so we fed the relevant information to Liu Xiang and coach Sun Haiping who are preparing for the final in Athens.

Finally, the fact is exactly the same as expected. Finally, in the ninth column, Du chore was out of balance in the tenth hurdle because he was in a hurry to catch up with Liu Xiang.

Then Liu Xiang won the Olympic gold medal, which is the success or failure of the details.

　　劉翔屬于一點就通的運動員

Some people will ask "Xiang Xiang team" such a question: "do you always face these data boring?"

Li Tinghui told him, "to serve genius is not for decades."

Liu Xiang once mentioned in a TV interview that he was grateful to researchers for his help.

Li Ting thought this sentence would be enough.

Li Ting told reporters: "generally speaking, science and technology are the primary productive forces, but there is a very big difference between sports scientific research and other aspects of scientific research. First, the object of sports scientific research is the soul of all things, and this person is highly talented.

All of these Olympic gold medalists are gifted. Coach Sun Haiping told us that Liu Xiang's intelligence is very high, for example, a question for the same athlete, some people may understand only two of them, but Liu Xiang belongs to the same athlete.

"Xiang Xiang team" also set up Liu Xiang's "life support group". The life security group is composed of six people, all of whom are from Liu Xiang's hometown, Shanghai.

He designed the dishes for weight control, scientific intake and suitable for sprinter and jumper.
