The new season has begun.

Powell ran a good result of 9.80s again. Guy has not played in the competition recently, nor has he participated in the competition plan, and the team has not explained anything, but it is not frequent at the beginning and there is nothing to raise questions.

Blake also shot out 9.81s again, and this time there was almost no wind, only 0.3M/S.

This result also shows again that he did not just burst out for a moment. He was well prepared this year, and it also proved that his first shot at the first 9.79s at the beginning of the season was not a joke. The sentence "There is no regrets, I will run out next time" now looks... full of persuasiveness.

Oh my God, what's going on now? Did these people start to get fucked at the beginning?

This is the beginning of the season.

Bolt was no less than that. He made a 9.85s Grand Prix in Kingston.

Many people have calculated the hard power of this shot, and it is estimated that the hard power will be opened by 9.80s.

Bolt originally came out very late in his previous life. This was because his body was too indulgent and relaxed last year, which led to sudden training that increased some injuries and caused adjustments for a long time. However, this problem did not exist at all in 2011 at this time.

Last year's "defeated defeat" made him extremely serious in this winter training and started very early.

Not to mention the training madman Blake, at least Bolt has been extremely serious in his training career. Even Mills expressed satisfaction with his training status this year. Generally, he didn't smile much, and sometimes he had a little more smile on his fat face.

For Mills, Bolt, who can complete the training content he has arranged is enough.

He never thought Bolt would "train madly" like Blake.

So after the game, Bolt smiled and answered the media's question: "I'm ready this year."

"You all know."

"In the year of the competition, I, Usain Bolt, never lose my chain!"

"My condition has begun to recover, and no one can surpass me this year!"

This was said with confidence, and it immediately made a fuss for Bolt's fans who had been suppressed for a year last year, and it became popular. They left messages online to express their expectations for Bolt's new season.

At this time, Ome Media had a huge title———————————————————————————————————————————Office.

Nouns have also been officially accepted by a large number of people.

[Only the competition can arouse my Boss’ seriousness! The little Bosss’ plays all the house!]

[Last year, Bo Shuai was careless and didn't flick. This year, see who can stop him.]

[The competition is strong and the real strength! Bolt is the strongest in history, no one can get close to it!]

Well, Bolt does have such influence, and Su Shen has no doubts. And among the few super experts, he has not made his debut, so he has to stand up and make his debut.

Give him a reassurance to the fans and audiences who support him.

And this first battle was in the Diamond League in the Magic City.

The doorstep also saves the trouble of rushing and rushing.

It can be said that it is a matter of waiting for labor.

It has taken a lot of geographical advantages.

Last year, Su Shen’s Diamond League was unbeaten, and even gave the audience of the Magic City a lot of room for longing and imagination.

Countless people are looking forward to Su Shen showing his power again in the Demon City and defeating all the "invaders".

This topic has caused discussion online. Although there are many opponents who have broken through ten this time, there should be still a gap in Su Shen who can play well.

This made Su Shen's shot seem to be sure to win.

The promotional video also began to come out, and of course it was led by Liu Xiang and Su Shen:

"From the start, there are eight steps between the first bar, we will cross 10 bars, cross the last bar and sprint until the end. And this time my choice is seven steps, fewer, which means faster."

"From the start of the start, to the 100-meter, there are more than 40 steps, from starting to acceleration to the running and sprinting area on the way, you can't relax every step, you need to take it seriously. The record of this stadium is mine. If you want to win here, you have to ask me first."

Regarding Liu Xiang's seven-step introduction to the bar, this year it was really beginning to explode. Last year was not mature enough, and there were too few outdoor competitions, which led to many people not paying attention to this aspect at all.

This year's reports are obviously increasing.

Of course, this is also because Liu Xiang’s team did not intend to conceal it.

Anyway, my opponent knew that he had started to change last year, so it would be better to be generous and tell everyone.

Liu Xiang relies on his hard power to win. As the world record holder and the first Grand Slam player in hurdling history, he has been studied by countless people and does not need to be hidden.

Various newspapers and websites have also begun to promote a lot, allowing netizens and the public to realize the new word "Eight Changes and Seven" in their minds for the first time.

[The seven-step starting point requires the starting foot to change from the right foot to the left foot, which is not easy, but Liu Xiang actually had this idea long ago to change this step. Robles had used it for many years when he was in the hurdle. Oliver of the United States began to emerge at the age of 26. In the past year, he has won 18 international competitions and achieved the world's first record. It was inspired by them that Liu Xiang decided to change his skills

"For a while, I have been thinking about how to speed up the center of gravity movement. This is a skill that Robles and Oliver have mastered. I should try it. I want to challenge myself. In fact, in terms of starting, I am a little worse than Robles, Oliver and others. So, I want to narrow the distance between them in the first half." Liu Xiang said, "I should have the strength I can master, and my team and coaches think I can do it."]

[The most important thing in the 110-meter hurdle competition is the footwork after the start. Liu Xiang put in a lot of effort to change the first seven steps, which is a symptom change. Sun Haiping told reporters: "Before, Axiang needed to adjust his steps when he was in a hurdle. Just like when he was in a hurdle, he needed to adjust his steps. You can't use too much force, otherwise, he would rush directly to the front of the railing. In that case, the first bar would become a jumper. Now, he only needs to adjust his steps.

With an easy hurdle," Sun Haiping explained: "In this way, the time taken from the start to the hurdle will be shortened accordingly, which is also the advantage of the 7-step hurdle. In fact, if this change can be successful, it will make up for Liu Xiang's shortcomings of poor performance in the past hurdle competition. According to reports, so far, Liu Xiang's "seven-step technology" has achieved success rate of 90%. After half a year of winter training, the highlights of the new technology will be tested the day after tomorrow.]

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! [What will happen if you fail? Experts claim that if you fail, Liu Xiang will directly withdraw from the ranks of the world's top contenders. So is it a bit risky to make such technical adjustments less than a year and a half away from the London Olympics? Let's wait and see.]

Of course, there are those who support it, and there are those who oppose it. For example, Sun Haiping's friend Yang Guorong, who is now coaching in Shancheng, said: It doesn't exist! I must ask him in the next game, is he kidding me if he does this?

Yang Guorong's point of view is that from an 8-step hurdle to a 7-step hurdle, it requires more foot strength. The same distance, reducing one step means that your stride will become larger and the stride frequency will become slower. This means that Liu Xiang's soles of his feet will touch the ground longer, and he is likely to be unable to bear it because of too much pressure. Moreover, even a top athlete wants to completely change the existing technology, it will take several years to make it possible, and it is normal for the entire Olympic cycle to be complete. He thinks it is still a little too anxious.

Seeing that professional coaches started to come out and said they were not optimistic, many people also became worried about "following the crowd".

This is a common problem after the rise of the Internet era in China. Sometimes this, sometimes there are some messages, too many and messy news, but instead it has become the ability to distinguish the recipients of their self-discrimination, and the requirements have also been improved.

Otherwise, you will easily be taken away by a few news and fall into blind pessimism or blind optimism.

Of course what he said is not without problems. As a athlete who is carrying the tripod like Liu Xiang now, Su Shen must be asked about this hot topic. Facing the reporter, Su Shen said calmly: "Although the amplification of the pace requires higher strength on the entire leg, due to the slowdown of the frequency of exertion, it may cause the Achilles tendon to be less stressed, and to a certain extent, the stimulation of the injury is slightly smaller."

"There are too many points that can be avoided, such as leg strength recovery problem. If you use scientific training to strengthen the entire injured leg and the core of the entire injured leg during this stage, you can use this period to make up for shortcomings. For example, Jordan, the NBA, became stronger after recovering from a rookie when he was a rookie. This is the principle."

"It's hard to say for specific reasons, but I think I believe Brother Xiang. He is the one who is a group of gold medals in the Olympics, gold medals in the World Championships, and world record holders. I am far from his realm now, so I am just like everyone else. I am looking forward to how Brother Xiang's performance will be this year."

Faced with this problem, Shi Dongpeng, the second largest in Asia, was also surrounded by reporters, and even reporters asked him brainlessly why he didn't change.

It seems that this kind of starting foot replacement is as simple as playing house.

Dashi could only respond with a wry smile: "You may not know that from the starting line to the 13.72 meters distance from the first railing, he will shorten it to 7 steps. This means that the distance he crosses each step after the start is greater, and the requirements for explosive power, power distribution and rhythm control are also higher. This means that the rhythm of the entire competition will be changed. At present, it is still difficult for me to bear it. Liu Xiang in Asia may have this ability."

Some reporters also asked in a slight manner: "But it can be improved by 0.1s, which is said to be two levels. Isn't it a pity not to try it?"

This is what I said... If the technological change fails, it may drop sharply.

At that time, it is hard to say whether it can still be competitive in the international market.

"I can't try it at the moment because I don't have enough explosive power. Everyone's situation is different, and the tactics must be formulated based on their own characteristics. So I won't adjust it for the time being."

Shi Dongpeng is to be honest. Everyone really thinks it is a technical change, but in fact, it has extremely high requirements for talent and understanding. In fact, Shi Dongpeng can't get through the first talent level alone.

Liu Xiang can become a world record holder in this backward team system and training system.

What do you think is his talent?

His explosive power is relatively weak, which is also compared to the top opponents in history. He has won the indoor competition championship. I really think he is not the top explosive talent of the yellow race? At least in the hurdle field, it is absolutely true that the foot strength is incomparable to ordinary people.

The cruel point is that you may not be as talented as others in nature when practicing hard.

So Shi Dongpeng couldn't try it, it was not because he didn't try it.

Otherwise, it can be improved by such a simple way, and whoever doesn't want is a fool.

Sometimes the questions asked by reporters are indeed amateurs and brainless, which makes athletes and insiders very embarrassed.

At this time, experts from all walks of life also encouraged them. For example, Han Qiaosheng praised: Liu Xiang’s courage to change his skills and pursue the championship is worthy of respect.

As the whole world, there are only four people.

If he could master it, he would be the first yellow man.

This technique can be learned for yellow people and set the best example.

Faced with this problem, some mathematical models are more representative. According to a research paper in the United States, we can know that under theoretical conditions———

Advantages 1. Reduce one step 2. It is more conducive to moving the center of gravity forward.

Disadvantages 1. The rate slows down 2. The pressure increases, which can easily lead to injuries 3. After the first column, you need to run the second column quickly and quickly convert.

Liu Xiang did this to avoid direct right foot activation and reduce recurrence of injuries. The first blow to the outbreak is the most violent, starting from stillness. However, the pressure on the feet is also greater, which may lead to new injuries.

This is what the team needs to solve and weigh it on its own.

According to the statement of this paper:

Results improved: about 0.05 seconds-0.1 seconds.

Strip change: Each step increases by about 0.245 meters.

8 steps are about 1.715 meters per step (the distance between the starting point and the first column is ignored).

7 steps are about 1.96 meters per step (the distance between the starting point and the first column is ignored).

Each step adds about 0.245 meters.

This chapter is not over, please click on the next page to continue reading! Rhythm changes: There is no need to slow down and adjust before the first column.

For tall athletes, the distance between each step must be reduced by 8 steps, which has a certain impact on mastering the rhythm. In the process of the first three columns, Liu Xiang must use support, otherwise it will be easy to be confused, which to a certain extent also limits the speed of the first three columns. There is no problem with the seven-step column.

Changes in strength, center of gravity, speed: improve explosive power.
