Ersha Island.

Except after a wave of "Forbes turmoil".

Su Shen then came back to continue training, waiting for this collective test.

Especially after having a 60-meter foundation, how to integrate the "credit card landing" technology into 100 meters feels much better.

For the remaining two months, he thought he could definitely do well.

Or even completely through.

In actual combat, the degree to which it can be displayed at will.

Liu Xiang's level is also rebounding sharply, which is the advantage of having surgery early, and it has been more than half a year of recovery. The original timeline only started at the end of December, and it was actually wasted for nearly half a year. With this half a year, and Su Shen and Ralph. Man's full help, Liu Xiang's speed, and the recovery was very fast.

At least, it was the speed that Sun Hai had not dared to predict before.

In the original timeline, Liu Xiang would make a comeback in September 2009, although he ran a good score of 13.15s in the first game, but then entered a continuous decline. Obviously, this is because the body has not fully recovered, and the 7 shots for a whole year, except for 13.15s, the rest of the scores are 13.75, 13.45, 13.82, 13.50, 14.02, and 13.66.

That is, except for the 13.15s of the first shot, the average score of the rest is 13.70s.

This is a pretty bad average.

But because of the 13.70s in the Asian competition, it can't be the king.

However, Liu Xiang, who shot the first shot, still achieved a good score of 13.15s after recovering his physical condition for a period of time, which is already an absolute hegemonic result in Asia. Therefore, as long as he adjusts well, this time with half a year and the full system technology support of the Su Shen Department, he will only be better, not worse.

At this time, the previous basic training began to show results.

By April, Liu Xiang had recovered to his best score of 13.30s, and his average score could also reach 13.50s. And 13.30s, which is already very strong in Asia, goes down at this rate, in the words of Ralph Mann:

Definitely in time for this year's World Championships.

You can definitely get back to the OW level before the World Championships.

And this is still a result in the case of good conditioning, not forced play, Sun Haibei didn't expect that in the case of so little special training, it could improve so quickly. Even because of Ralph. Man himself is a former world record holder in hurdles, so he can also give Liu Xiang a lot of tips and tricks.

This point is incomparable to Sun Haihua.

Sun Haihua is also learning to be obedient now, honestly gnawing books on Ersha Island, and then honestly following Ralph. Mann learns the real science hurdle system and pedagogical applications.

As soon as my heart sank, I really felt a real improvement.

Sun Haihua probably didn't even think that he would accept the transformation of the Su God system so quickly.

Nothing is deliberate.

It is the accumulation of time that changes the past.

Looking back now, I can immediately feel the nobility of my knowledge system and the unscientific nature of my training.

This has an unwritten rule in the "Su Shen Department" and even on Ersha Island, that is-

If your scientific training is not good and your grades are not good enough, then it can only mean that you are either lazy or ...... Your training is not scientific enough.

Not only restorative training, but also Liu Xiang's technical convergence transformation, it is also through this time to carry out a major transformation.

For example, technical links and technical details are better connected.

For example, how to form a more smooth transmission power chain.

For example, how to reduce energy loss through technology.

Otherwise, in the words of the Su Shen Department: no matter how good and awesome your single technique is, you will still lose a lot of energy in vain.

That's one of the reasons why you're running slow.

Again.

Liu Xiang's technical movements, many of which are incomplete and unsystematic, just rely on his own talent to be high enough hard top, just this time, you can also take this opportunity to restructure it, so that his future technical links are closer and smoother.

For example, in this timeline, by Ralph. The ———— seven-step hurdle technique that Man proposed early on for Liu Xiang to start training.

The first person in the world to adopt a seven-step hurdle was Finland's Brugaret.

The reason why the Nordic flyer dared to eat "crab" was because he reached a height of 2.04 meters. Brugaray, who was tall and legged, even felt "aggrieved" with an eight-step hurdle, invented the seven-step hurdle, a new technique that helped him win third place in the 110m hurdles at the 1984 Olympics and silver in 13.46 seconds at the inaugural World Championships in 1986. However, at that time, this technology seemed to be only a special personal technical change, and it did not have the significance of promotion. It was really paid attention to after the 21st century, such as Robles, who started with an eight-step bar, and then because of the gradual scientific and data-based refinement of the seven-step bar, they all changed to a seven-step start.

Generally, those with long legs and strong explosiveness use seven steps, and those with medium body use eight steps.

Liu Xiang was killed by Ralph. After Man tested his body ratio, the latter told Liu Xiang with certainty that he had the physiological conditions to make such a change. And as long as it is changed in this way, the lack of speed in Liu Xiang's first few columns will be qualitatively changed, or even greatly improved. The advantages of changing eight steps to seven steps are very obvious, Ralph. "One step less, if you follow the previous cadence, it will definitely shorten the time. In addition, the new technology also helps to shift the center of gravity forward. Because of this feature of the seven-step upper bar, its backward pedal force is greater than that of the eight-step upper bar, and its forward performance is better than that of the eight-step bar, and it is more active when attacking the bar. ”

Mathematically calculated alone: Liu Xiang had completed the 110-meter full course in about 41 steps before, and assuming a time of more than 13 seconds, the average time per step would be more than 0.3 seconds, which means that he would save at least 0.3 seconds if he ran one less step. Considering that the starting running frequency is higher than the cadence between the hurdles, and the length of each step is increased by about 0.245 meters after changing to 7 steps on the hurdle, it will also take more time. Therefore, after the successful transformation of technology, the performance is improved by 0.1~0.2 seconds relatively objectively.

However, the specific results of the application still need to be trained.

And at the current stage of technological reform, to be honest, Sun Haihua does not agree.

This is exactly the same as in the original timeline.

After all, athletes who have been using eight steps for a long time to change to seven steps, and they need to change their front and rear feet when starting, which requires increasing the force of this leg muscle to push off the starting block and changing the firm power stereotype that has been formed over the years, which also takes a certain amount of time. Grades may fluctuate during the transition.

This is the "unbearable" weight of Liu Xiang's comeback.

In other words...... Not insured.

Of course, from a purely technical point of view, Sun Haihua does have his own concerns, for example, in his opinion, it looks like "eight to seven", Liu Xiang's height of about 190cm is still not tall enough, once the seven-step upper bar is not adjusted well, it will lead to too close to the first column, and at the same time, he will only be too far away from the second column. And there are also examples of the failure of "eight to seven" in short crossovers, such as Alain. Johnson is a prime example.

Due to the extremely high requirements of athletes and the risk of injury, the vast majority of 110m hurdles athletes are mainly using the eight-step hurdles.

In fact, before Liu Xiang, only four people had used the seven-step upper bar technique.

The first person in the world to adopt a seven-step hurdle is Finland's Brugaray, who became the first person to try to change from eight to seven with a height of 2.04 meters, followed by Cuban genius Robles with a height of 1.92 meters and Oliver of the United States with a height of 1.88 meters. If Liu Xiang does it, it will be the fifth.

This is definitely still a "too far ahead" concept, because the number of users is too small.

Besides, if Liu Xiang fails to change technology, Sun Haihua can't afford the risk of failure.

On this point, Sun Haihua also and Ralph. Mann expressed his opinion, and the latter's answer was much more professional:

First of all, from the perspective of Liu Xiang's body proportion, the test shows that it is completely in line with the body proportion of eight to seven.

Secondly, there are also players who are shorter than Liu Xiang, and the eight to seven have been successful, such as Oliver, the flying man of the United States.

Secondly, he believes that through science to increase muscle strength, Liu Xiang can also do it.

This is where the biggest disagreement is, Sun Haibei feels that although Oliver is not as tall as Liu Xiang among several people, the exceptionally strong figure of the Mi people has become the key to his success, and he once joked that Oliver's hands are thicker than Liu Xiang's legs. In his opinion, Liu Xiang's advantage in standing on the top of hurdles relies on flexibility and rhythm, and his strong muscles are too strong and can become stiff, which undoubtedly affects Liu Xiang's strongest essence, that is, the flexible use of hurdle techniques.

But this point, Liu Xiang himself also stood up and said, just like the original timeline Liu Xiang resolutely insisted on "eight to seven".

Liu Xiang said:

I want to train more advanced running styles.

And he is very worried that after his injury, his physiology will decline compared to a few years ago, and the technological leadership may be especially important at this time.

Finally, after this period of training, he clearly felt the typical famous saying of the Su Shen Department————

Use your body to harness the technology.

In the past, there was no scientific basis for what China thought of Xiao Kuailing, and Asians can also be very strong, and their muscles can also be very explosive, after all, our testosterone is also the highest piece.

In this case, Liu Xiang only wants to say that he has clearly felt the difference through his winter training.

He believes that his body is enough to handle this "new technology".

What he wants is to be crowned champion again in the next Olympic cycle, not just to make a comeback with a "good" result.

In this case, Liu Xiang finally passed Sun Haihua, and finally the training of "eight to seven".

Thanks to Ralph. Man has been strengthening the muscles around his body and the injured area, and as long as the Achilles tendon does not recur, I think the former should be able to support it.

As for changing feet, Su Shen can also give him help and advice.

Although he knew that even if he didn't say it, Liu Xiang could rely on his talent to successfully change feet.

Even now Liu Xiang doesn't know his future, but Su Shen praised Liu Xiang's "bravery".

It is worthy of being one of the domestic track and field leaders.

This bit of courage is still there.

Really the first person to overhaul the technique of eating crabs.

All track and field fans are afraid to remember.

Among the top domestic athletes.

Su Shen is not the first.

Liu Xiangcai is.

It was also his success in changing feet and trying skills that paved the way for the track and field team behind him.

In addition to Liu Xiang, the rest of the training is also in full swing.

For example, the adjustment of Wen Yongyi's swing arm technique.

The dynamic chain link of Lao Da Niu is optimized, and the joint rigidity of the body is strengthened.

Zhang Peimeng's second-gear start + modification of the gluteus maximus core drive running method.

and Zhao Haohuan and Su Shen's "credit card landing" technology overhaul.

There is also the overall overturning and improvement of Hukai's technology.

The entire Ersha Island.

Before the group debut, they all entered the final intense sprint.
