The Su God of the Reopening of the Sports Arena

The new season has begun.

Powell once again ran a good result of 9.80s. Gay did not play recently, nor did he plan to participate, and the team did not explain anything, but it was not frequent at the beginning and did not cause any doubts.

Blake also blasted 9.81s again, this time with almost no wind, only 0.3M/S.

This result also proves once again that he didn't just break out temporarily, he was fully prepared this year, and it also proved that his 9.79s in the first shot at the beginning of the season was not a joke. The sentence "I don't have any regrets, just run out next time", now it seems...full of convincing.

God, what's the situation now, did these people start having convulsions in the first place?

This is just the beginning of the season.

Bolt didn't give up too much. In a grand prix in Kingston, he made a big release of 9.85s.

Many people have calculated the hard power of this gun, and it is estimated that the hard power has been opened for 9.80s.

Bolt originally came out very late at this time in his last life. This was because his body was too indulgent and relaxed last year, which led to a sudden increase in some injuries in training, which led to a long period of adjustment, but this problem did not exist at this time in 2011.

Last year's "fiasco" made him take this winter training very seriously and started very early.

Not to mention the same as training crazy Blake, at least Bolt has been extremely serious several times in his own training career.Even Mills expressed his satisfaction with his training status this year. His fat face, which usually doesn't smile much, sometimes has a little more smile.

For Mills, Bolt who can complete his own training content is enough.

He also didn't think that Bolt would "train like crazy" like Blake.

So after the game, Bolt smiled and answered questions from the media: "I'm ready for this year."

"You all know that."

"Big race year, I, Usain Bolt, never lose the chain!"

"My condition has all started to recover, absolutely no one can surpass me this year!"

This statement was so swearing, it immediately became popular among Bolt fans who had been suppressed for a year last year, and they immediately flourished. They left messages on the Internet expressing their expectations for Bolt's new season.

At this time, Omi Media has a huge headline —————— Big Bo.

Nouns are also officially accepted by a large number of people.

[Only a competition can arouse my seriousness!Little Saibo Shuai is playing house! 】

【Last year Bo Shuai was careless and didn't flash, let's see who can stop him this year. 】

[The competition is strong to be really strong!Bolt is the strongest in history, no one can come close! 】

Well, Bolt does have such influence, and Su Shen has nothing to doubt, and among the few super masters, he is the only one who has not made his debut, so he has to stand up and make his debut.

Give the fans and audience who support him a reassurance.

And this time the first match was in the Diamond League in Shanghai.

It also saves the trouble of traveling and traveling at the door of the house.

It can be said to wait for work with leisure.

Occupied a lot of land.

Last year's Sushen Diamond League, an unbeaten game also gave the audience in Shanghai a lot of room for longing and reverie.

Countless people are looking forward to God Su showing his power again in the magic city and defeating all "invaders".

Regarding this topic, there have been discussions on the Internet. Although there are many opponents who have broken the top ten this time, according to Su Shen's ability to perform well, there should still be a gap between them.

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

Promotional videos also started to come out, naturally led by Liu Xiang and Su Shen:
"From the start to the first hurdle, there are eight steps, and we have to cross 10 hurdles, and then sprint after crossing the last hurdle, until we reach the finish line. This time, my choice is seven steps. Fewer means faster."

"From the start, there are more than 100 steps to the 40 meters. From the start to the acceleration to the midway run and the sprint area, every step cannot be relaxed and needs to be taken 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 uphill, this year it really started to explode. After all, last year was not mature enough, and there were too few outdoor competitions, so many people didn't pay attention to this aspect at all.

This year's coverage has obviously increased.

Of course, Liu Xiang's team did not intend to hide this.

Anyway, the opponent knew that he had started to change last year, so he might as well be more generous and tell everyone.

Liu Xiang relied on 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 there is no need to hide it.

Various newspapers and websites also started a large amount of publicity, making netizens and the public aware of the new term "eight changes to seven" for the first time in their minds.

[Seven-step starting requires changing the starting foot from the right foot to the left foot, which is not easy, but Liu Xiang actually had this idea long ago to change this footwork.Robles has been using it for many years when he is hurdling.On the other hand, Oliver from the United States only started to emerge when he was 26 years old. In the past year, he has won 18 international competitions and achieved the world's number one result.It was inspired by them that Liu Xiang decided to change his technique. "I have been thinking about how to speed up the movement of the center of gravity during this period of time. This is a skill that Roberts and Oliver have already mastered. I should also try it. I want to challenge myself. In fact, in terms of starting, I am worse than Roberts, Oliver and others. Therefore, I want to shorten the distance between them in the first half." Liu Xiang said, "I should have the strength that I can master, and my team and coaches believe that I can do it."]

[In the 110-meter hurdles competition, the most important thing is the footwork after the start. Liu Xiang put in a lot of effort to change the first seven steps, which is a symptomatic change.Sun Haiping told the reporter: "Ah Xiang needed to adjust his pace when he was hurdling before. Just like when he was hurdling, he needed to adjust his pace. He couldn't use too much force. Otherwise, he would rush directly to the hurdle. In that case, the first hurdle would become a hurdle jump. Now, he only needs to adjust his pace and he can easily hurdle the hurdle." Advantages. In fact, if this change is successful, it will make up for Liu Xiang’s poor performance in hurdling competitions. According to gossip, the success rate of Liu Xiang’s "seven-step technique" has reached 7% so far. After half a year of winter training, the highlights of the new technology will be tested by you the day after tomorrow.]

【What happens if you fail?Experts claim that if he fails, Liu Xiang will directly withdraw from the ranks of the world's top contenders.So is it a little risky to make such technical adjustments when the London Olympics is less than a year and a half away?let us wait and see. 】

Of course, if there is support, there is opposition. For example, Sun Haiping's friend Yang Guorong, who is now coaching in Shancheng, said: It does not exist!In the next game, I must ask him, is he joking with me?

Yang Guorong’s point of view is—————The change from 8-step hurdles to 7-step hurdles requires more footwork.For the same distance, one step less means that your stride length will become larger and your stride frequency will become slower. This also means that the time for Liu Xiang's feet to touch the ground will be longer, and he may be unable to bear it due to excessive pressure.Moreover, even for top athletes, it will take several years to completely change the existing technology, and even the entire Olympic cycle is normal.He thought it was a little too hasty.

Seeing that professional coaches are beginning to come out and say that they are not optimistic, many people also worry about "following others".

This is a common problem after the rise of the Internet era in China. There are too many messages and too many messy messages. On the contrary, it has become a requirement for the receiver's self-discrimination ability.

Otherwise, it is easy to be carried away by a few news, and the whole person falls into blind pessimism or blind optimism.

Of course, what he said was not without problems. Su Shen, as an athlete like Liu Xiang now, must be asked this hot topic. Facing the reporter, Su Shen calmly said: "Although the increase in pace requires higher strength of the entire leg, due to the slowing down of the frequency of exertion, it is possible that the force on the Achilles tendon will be less, and to a certain extent, it will be less irritating to the injury."

"There are still too many points that can be avoided. For example, the recovery of leg strength. If you combine scientific training and take advantage of this stage to strengthen the entire injured leg and the overall core, you can use this period to make up for shortcomings. For example, Jordan in the NBA was even stronger after recovering from a hand injury during his rookie period. This is the principle."

"It's hard to say the specifics, but I think I believe in Brother Xiang. After all, he is an Olympic gold medal + world championship gold medal + world record holder. I am far away from his realm now, so I, like everyone else, am looking forward to how Xiang will perform this year."

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

It seems that this kind of replacement of starting feet + major modification technology is as simple as playing house.

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

A reporter also asked in a corner: "But it can be improved by 0.1s. It is said that it is two grades. Wouldn't it be a pity not to try?"

This is what I said... If the major technical changes fail, it may directly decline sharply.

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

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

Shi Dongpeng was telling the truth. Everyone really thought it was just a technical change, but in fact, it had extremely high requirements for talent and understanding.In fact, Shi Dongpeng couldn't pass the first talent level alone.

Liu Xiangneng became the world record holder in this backward team system and training system.

What do you think his talent is?
His explosive power is relatively weak, which is compared to the top opponents in history, and he has won the indoor championship anyway. I really think it is not the top explosive talent of the yellow race?At least in the field of hurdles, absolutely, this foot strength is incomparable to ordinary people.

To put it cruelly, if you practice hard, you may not be as talented as others.

So Shi Dongpeng couldn't try, it's not that he didn't try.

Otherwise, it can be improved so simply, and whoever does not want to is a fool.

The questions that reporters sometimes ask are indeed amateurish and thoughtless, embarrassing for athletes and professionals alike.

At this time, experts from all walks of life are mostly encouraging. For example, Han Qiaosheng praised: Liu Xiang's brave heart to change technology and pursue the championship is worthy of respect.

There are currently four people in the world plus Liu Xiang.

If he can master it, he is also the first person of the yellow race.

It is the best example for people of yellow race to learn this technology.

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

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

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

Liu Xiang did this to avoid starting with his right foot directly and reduce the recurrence of injuries. The first blow of the explosion is the most violent, and he must start from a standstill.But there is also more pressure on the feet, which could lead to new injuries.

This is something that teams need to figure out and weigh for themselves.

According to the statement of this paper:

Performance improvement: about 0.05 seconds -0.1 seconds.

Stride length change: each step increases by about 0.245 meters.

Each step of 8 steps is about 1.715 meters (the distance from the starting point to the first hurdle is ignored).

Each step of 7 steps is about 1.96 meters (the distance from the starting point to the first hurdle is ignored).

Each step increases about 0.245 meters.

Rhythm changes: No need to slow down before the first hurdle.

For tall athletes, 8 steps must reduce the distance of each step, which has a certain impact on mastering the rhythm.In the process of the first three hurdles, Liu Xiang has to use his support well, otherwise it will be easy to mess up, and this also limits the speed of the first three hurdles to a certain extent.The seven-step upper column does not have this problem.

Power, Center of Gravity, Speed ​​Change: Improve explosive power.

These detailed data, in fact, have already been studied in detail abroad. In this regard, the short-span business in my country is indeed in comparison, and there is still a big gap.

If you don't make a good effort to catch up, it is estimated that the gap will only widen, and it will not be easy to narrow.

Of course, some people came to join in the excitement, and there was a wave of "Zhouyi divination", and they came up with the number of yin: six, old yang: nine, shaoyin: eight, and shaoyang: seven.Yang dominates ascending and develops forward and upward; Yin dominates descending and develops backward and inward.Therefore, the seven representing yang is up, the eight representing yin is down, and the hexagram of auspicious hanging.

It also makes people a little dumbfounded.

As soon as Liu Xiang comes out of this game, he will directly face the American player Oliver, who has increased his winning streak to 19 games and set a world best time of 13 this year.

Oliver took part in an international competition held in the Latin American island nation of Saint Christopher and Nevis, capital of the Commonwealth of Basseterre.Because the outdoor season has just started, and the influence of the competition is small, the 110-meter hurdles competition did not attract too many players.As a result, in the case of a wind speed of 1.2 meters per second, Oliver was the first to cross the finish line, surpassing No.2.Jamaican veteran Thomas won the championship in 0.16 seconds.It was his fourth international title of the year and his 4th consecutive unbeaten run since April last year.

The last time Oliver lost in a competition dates back to the 3-meter hurdles final of the Indoor World Championships held in Doha on March 14 last year. At that time, he lost to Cuba's Robles and another American player Trammel and won the bronze medal. Twenty days later, on April 60, Oliver started his outdoor competition journey in Gainesville, the United States. He participated in the 20-meter hurdles competition 4 times that year, and won 2 consecutive victories unstoppably.

This record has already approached the historical record of 1993 consecutive victories in a single season by Jackson, a famous hurdler in Kitty Hawk Country in 17.

不过奥利弗的15连胜中包括8次跑进13秒10、5次闯入13秒大关，整体水平却是当年杰克逊望尘莫及的。今年元月到2月，奥利弗又在格拉斯哥、斯图加特、卡尔斯鲁厄连续参加了三次室内60米栏比赛，全部夺得冠军，将自己的连胜纪录增加到了18场。加上几天前刚刚在巴斯特尔获得110米栏第一，他已经是19连胜在握。

In 2009, Oliver's first 110-meter hurdles race was 13 seconds, and his personal best time was 29 seconds. After the successful technical transformation, last year, his 13-meter hurdles performance was 09 seconds, and his best time in that year was 110 seconds.This year he crossed the 13-meter hurdles for the first time, and his score reached 32 seconds, which is rare in recent years.On the one hand, this is due to the brilliant record last year, which greatly increased his confidence; on the other hand, the late bloomer of the American "flying man" has indeed reached a new level in terms of strength and stability. No wonder he is also full of confidence in the face of Liu Xiang.

Claiming that he can't wait to come to Shanghai to participate in the competition.

It is undoubtedly appropriate to use the world championship as a footnote for his 20 consecutive victories.

Although he said this with a smile, which was a bit of a joke, it was obvious that there was a serious meaning in it.

He is in such a good state, 19 consecutive victories and unbeaten, what else can stop him now?
When he made his debut this year, Oliver directly shouted—————The goal is the gold medal in Daegu.

Such shouting.

Enough to show its domineering.

Although Liu Xiang won the 11-meter hurdles three times in a row in 13 seconds at the Yangcheng Asian Games in November last year.Let Xiang fans really excited for a while.But this result is basically not comparable to Oliver last year.

This is a fact, and there is no need to deny it. Oliver, who has won 19 consecutive victories, is currently short-spanning all over the world, and he is the most in the limelight.

Therefore, the recent data and news presented at the moment are not only that the European and American media believe that Liu Xiang has basically no chance of winning this game, but many "seemingly neutral" media in China also echo these lighthouse media, thinking that the probability of Liu Xiang successfully winning the championship is too low.

Some people even joked that it was harder than "the iron tree blooming".

Facing such a powerful opponent, Liu Xiang himself faced the media directly at this moment, refusing to give in.

And he used the example of Sushen VS Bolt last year in Shanghai to cheer himself up, saying:

"Last year, Xiao Tian played in Shanghai. No one was optimistic about him before. He also met Usain Bolt, who is recognized as the number one in history, in his first show. At that time, there were countless people who looked down on him. I still keep some newspapers, just to motivate myself."

"But everyone knows the result now."

"He beat Bolt."

"Miraculously proving that the impossible is possible."

"Then started his undefeated season."

"I think in this regard, I should also learn from him and not be afraid of strong enemies."

"What's more..." Liu Xiang said with a smile on his face: "The current world record holder is still me."

"Oliver's PB hasn't surpassed mine yet."

These words immediately raised the first show of this year's Shanghai Metropolis Competition to a new level.

Many people have mixed feelings.

Encouragement, unbelief, reasonableness, and rhythmic ones abound.

A diamond league can actually play such a big magic.

This year's first show ratings.

It must be stable.

It depends on the performance of the athletes themselves.
