The Su God of the Reopening of the Sports Arena

Chapter 2445 Almost everyone activated level 10! Just asking this...

“Apart from Su Shen.”

"Zhao Haohuan's performance was also quite impressive. I didn't expect him to run a time of 9.64 seconds. Before, I thought he might have run too poorly, but now it seems I was overthinking it."

"He doesn't seem to run very fast because Su Shen runs too fast. Actually, his result is quite good."

"If we can deliver on our promises as much as possible in the plains, we have a good chance of winning the bronze medal."

"If that's the case, then even with Bolt and Suarez there, he would have a chance to win a medal, instead of having a chance to win a bronze medal like at the Daegu World Championships, where he only had a chance because Bolt wasn't there."

"Okay, the rest of the results are coming out one after another. Let's see how the others did."

The third-place result appeared on the large electronic screen.

no doubt.

Zhang Peimeng.

9.78? ? ?

at last.

Zhang Peimeng also strongly opened up a 9.80!

The triple overlay technology is now more advanced!
The "triple superposition technique" is the core of Zhang Peimeng's later technical system. It specifically refers to a sprint technique that uses the hip joint as the power axis and achieves efficient propulsion through the synergistic effect of three dimensions.
First, the push-off and swing motions are superimposed, that is, the push-off and swing motions under the leadership of the hip are synchronized and complementary in terms of force and energy.

Second, energy conduction superposition refers to the graded release and superposition of core rigid support and lower limb muscle elastic potential energy.

Thirdly, there is dynamic rhythm superposition, which means adaptive adjustment and connection optimization of step frequency and step length in each segment throughout the entire process.

Compared to Moscow in 2013, Zhang Peimeng's triple overlay technique here has changed significantly.

For example, in the 2013 competition, Zhang Peimeng exhibited typical characteristics of "high step frequency and short step length": his step length index was significantly lower than that of the top 8 athletes in the World Championships.

Even compared to Nesta Carter, who is 1.78m tall, there is still a gap.

Biomechanical analysis by Su Shen Laboratory shows that Zhang Peimeng's insufficient stride length stems from two core issues:

First, the forward extension of the hip joint is insufficient, and the forward extension distance of the hip at the moment of landing is 4-6cm shorter than that of Bolt, which limits the basic stride length.

Secondly, the degree of folding of the swing leg during the push-off phase is insufficient, and the swing speed lags behind the push-off speed, failing to form an effective "swing traction effect".

Under these circumstances, although his stride frequency in each segment was close to that of the top 8 finalists, the excessively high stride frequency consumed a lot of extra energy, resulting in low energy utilization efficiency throughout the race.

That is, what Lakers told him—

An imbalance between stride length and stride frequency limits propulsion efficiency.

Secondly, there is a disconnect between the pedaling and swinging movements, resulting in significant energy loss.

It is important to know that the efficient output of propulsion in sprinting depends on the precise coordination of push-off and swing, and Zhang Peimeng in 2013 had obvious deficiencies in this aspect.

Post-race video analysis showed that when his supporting leg extended to its maximum power, his swing leg had not yet reached its highest position, with a time difference of 0.012 seconds between the two peak power points, far exceeding the world's top athletes' standard of less than 0.005 seconds.

This disconnect leads to two problems:
First, the ground reaction force generated by the push-off could not be effectively converted into forward momentum through the swinging motion, and about 12% of the energy was lost due to the lack of coordination in limb movement.

Secondly, during the landing and cushioning phase, because the swing leg fails to reach the ground in time to form a balanced support, the supporting leg has to bear an additional 15% load, which exacerbates muscle fatigue.

Secondly, there's the issue of speed.

Data from the 2013 race shows that Zhang Peimeng's highest stride frequency occurred in the fifth segment (about 60-70 meters), and he could only maintain it for one segment before it began to decline. In contrast, top athletes such as Bolt could maintain a stable stride frequency from the 6th to the 35th step, and the decline in stride frequency in the last 10 steps was still controlled within a reasonable range.

From a biomechanical perspective, this decline stems from the combined effects of insufficient core control and depletion of energy reserves:
First, during high-speed operation, the core muscle groups fail to provide rigid support, causing the pelvis to sway left and right by 0.8°-1.2°, resulting in deviation of the hip delivery trajectory.

Secondly, the excessive reliance on quadriceps strength in the early stages resulted in low synergistic involvement of the gluteus maximus and hamstrings, insufficient activation of anti-fatigue muscle groups, and accelerated lactic acid accumulation.

Its ability to maintain high speed is weak, and it declines significantly in the later stages.

This is also a rather serious drawback.

If it is not changed, it will be impossible to break the 9.80-second speed barrier with a legal performance.

It is quite difficult.

Therefore, we have been working on this technical challenge for the past two years.

Fortunately.

Huang Tian deserves a caring person.

His team restructured these weaknesses and then addressed them one-on-one.

When stride length and stride frequency are out of balance, propulsion efficiency is limited. Therefore, the method of superimposing push-off and swing movements is adopted to reconstruct the balance between stride length and stride frequency.

The primary advancement of the triple-overlay technology lies in its reconstruction of the propulsion pattern through "hip-led push-off and swing synchronization," effectively compensating for insufficient stride length.

LakeKai positions the hip joint as the common axis of the push-off and swing motion using this technique.

It achieves the "peak superposition of push-off force and swing force".

Compared to Moscow, in Qingtang City this time, in terms of movement execution, when the supporting leg pushes off, the contraction of the gluteus maximus and the rapid folding of the hamstrings of the swinging leg are initiated simultaneously, and the time difference between the peak force of the two is shortened to less than 0.03 seconds.

This synchronicity brings two improvements:
一是髋关节前送幅度从2013年的26°提升至30°，着地瞬间髋部前伸距离增加5-7cm，步长指数提升8%，在维持步频优势的同时实现了步长突破。

Secondly, the forward swing speed of the swinging leg is increased by 12%, and the resulting inertial force pulls the supporting leg to extend in the opposite direction, thus increasing the extension efficiency by 10%.

Unlike the passive mode of "step frequency compensating for step length" in 2013, the new technology achieves synergistic effect between step length and step frequency, significantly optimizing efficiency.

When the coordination between the push-off and swing is disrupted, resulting in severe energy loss, an energy conduction superposition method is adopted: constructing a rigid kinetic chain of "core-hip-lower limb".

In response to the severe energy loss problem in 2013, the triple superposition technology constructs an efficient energy conduction system through the superposition of "core rigid reinforcement and lower limb elastic energy storage".

The core of this system is to form a "core-hip rigid chain", which controls the relative displacement of the thoracic cavity and pelvis within 0.1° through isometric contraction of the rectus abdominis and erector spinae muscles.

It represents a qualitative leap compared to around 1° in 2013.

During the energy conversion process, the technology achieves "two-level energy superposition": the first level is the elastic potential energy reserve of the lower limb muscles. Through the micro-stretching of the hamstring muscles during the landing cushioning phase, the impact force is converted into elastic potential energy, which increases the potential energy reserve by 25% compared to 2013.

The second level is the rigid transmission between the core and hip, which directly transmits elastic potential energy and active muscle contraction force to the trunk through a rigid chain, avoiding energy dispersion and loss during the transmission process. The force transmission loss rate has decreased from 12% in 2013 to below 4%.

This energy superposition mechanism allows Zhang Peimeng to obtain higher effective propulsion with the same amount of physical exertion, laying the foundation for maintaining speed in the later stages.

Regarding the issue of extreme speed, the approach taken is—

Dynamic rhythm overlay: Enables precise speed control throughout the entire process.

The triple-overlay technique, through "dynamic adaptation and seamless overlay of segmented rhythms," solved the problem of the highest cadence occurring late and lasting for a short time in 2013.

湖凯该技术将全程划分为“加速启动段（0-30米）”“极速构建段（30-60米）”“稳态维持段（60-80米）”“冲刺突围段（80-100米）”四个模块。

The step frequency and step size settings of each module are dynamically linked.

During the acceleration phase, the step frequency gradually increased from 4.2 steps/second to 4.5 steps/second, a 5% increase compared to the start-up phase in 2013, achieving rapid acceleration.

The high-speed construction section uses the technique of overlapping steps and swings to stabilize the stride frequency at more than 4.6 steps/second while continuously increasing the stride length. The time when the highest stride frequency occurs is brought forward to 40-50 meters, about 10 meters earlier than in 2013.

The steady-state maintenance phase utilizes an energy conduction superposition mechanism to control the step frequency decay to within 2%, extending the maintenance time to 20 meters, far exceeding the single-segment maintenance capability of 2013.

During the sprint breakout phase, a strategy of "slightly increasing step frequency + stabilizing step length" was adopted, and the step frequency was increased back to 4.5 steps/second.

This avoids the traditional sharp drop in speed in the later stages.

This dynamic, superimposed rhythm control makes the speed curve smoother throughout the entire process and significantly enhances the ability to maintain maximum speed.

This project is a major one for Hu Kai since he started taking on responsibilities on his own, and it is also a project that he personally oversaw.

You can still consult Su Sheng and Randy.

However, he has already taken charge of many aspects himself.

This is actually necessary, because both Randy and Ralphman will definitely leave the country in the future, since they are not Chinese and they are getting older.

If we cannot cultivate a group of teams and coaches in China who can solve problems independently in a localized manner.

So, in terms of the coaching team, there has been a significant gap in quality.

The best approach is while these people are still around.

Mentorship and guidance.

Combining the three points.

We are gradually cultivating our own excellent, scientifically sound education that integrates research and teaching.

Otherwise, you could try contacting Su Shen.

That would be too limited in terms of manpower to be applied nationwide.

Therefore, strengthening the training of outstanding local professionals is also of paramount importance and constitutes another crucial battlefront.

Hu Kai is the most suitable candidate and the one most likely to break through.

He has a high level of education and is currently pursuing a doctorate.

I joined the Su Shen faction early.

They have a deep understanding and assimilation of various core scientific knowledge.

Therefore, it is most appropriate for him to serve as the pinnacle of scientific coach training in China.

Furthermore, since this was the first time a domestic team had led such a top-level sprinter, the entire Hukai team was under immense pressure.

I don't know how many days and nights I've spent buried in research.

It's not even easier than when I was an athlete.

Ultimately, under Hu Kai's leadership, Zhang Peimeng's team developed a theory that evolved from "single action optimization" to "systematic power construction".

They believe that Zhang Peimeng's technical improvements in 2013 remained at the level of single movements, such as compensating for insufficient stride length by increasing stride frequency and improving push-off force by strengthening leg strength, but failed to form a systematic kinetic chain solution.

The essence of the triple-layer technology is to construct a "power generation-transmission-regulation" system centered on the hip:
The superposition of pedaling and swinging solves the efficiency problem of power generation, the superposition of energy transmission solves the loss problem of power transmission, and the superposition of rhythmic dynamics solves the regulation problem of power output.

The three elements support and coordinate with each other, achieving a leap from "local optimization" to "system upgrade," which aligns with the modern sprinting technology development trend of "hip-centric, whole-body coordination."

Ultimately, Zhang Peimeng achieved a breakthrough.

They opened the door to 9.80 seconds.

It has once again reached the 9.70+ level.

With this achievement, you can at least say that you are a world-class athlete.

Because of the giants.

That's the result.

Including Gatling guns from before this year.

That's it.

Besides.

Zhang Peimeng watched as the results appeared.

They couldn't help but smile.

He felt he deserved the achievement.

This achievement is the best reward for his hard work over the past two years.

"9.70+! Zhang Peimeng breaks the 9.80 mark!"

"Tonight has been full of surprises!"

"Our country now has three players with a 9.70+ Pb rating!"

"For relay races!"

"It's a huge boost!"

Fourthly.

Fourthly, work-rest balance resulted in a score of 9.83.

Although Lao Yi has modified the approach to simplify the technical endgame, he is still getting older and older, and it is already quite good that he can maintain his current state.

Further breakthroughs will likely become increasingly difficult.

However, maintaining this result is already very important for domestic sprinting, because if they lose a leg... then when facing the Jamaican team at the Bird's Nest.

There's a good chance they'll kill you.

Now the whole world knows that in relay races, the two final bosses are the Chinese team versus the Jamaican team.

No one else can interfere.

Team USA.

Not at all.

Although they won against Jamaica last time, Jamaica's growth was undeniable, and two years later, they have more time to develop Mills...

Who knows if it will get even stronger?

Moreover, even last time, several people miraculously experienced a power surge.

Perform at your best.

Even exceeding expectations.

They only won the game because of that; otherwise, they would have been at a disadvantage in Moscow under normal circumstances.

This point cannot be overshadowed by victory.

At least for the athletes themselves, for the sprint teams, and for the professional teams.

We must not forget these issues just because we have won.

Otherwise, you'll encounter it again next time.

The Bird's Nest in the country.

That would likely mean losing the chance to win.

that……

No.

Because it's in the country.

Winning a game on home soil is more important than winning it several times outside of your hometown.

While this may sound exaggerated, it reflects the reality for the athletes themselves. If you asked any athlete if their medals were changed to those of 08, would they be willing to accept it?

If you want to show your ultimate brilliance in the Bird's Nest.

No athlete would refuse.

Otherwise, Liu Xiang wouldn't have been so seriously injured yet still wanted to play.

Yao Ming would never have said that sentence: "No matter how many surgeries I have to have on my foot, or how many steel nails I need, as long as I can secure my Olympic Games."

That's the charm of having a competition held right on your doorstep.

Although Lao Yi hasn't made much progress, it doesn't matter; it's enough that the other three have made progress.

Work and rest are both important, as long as you can maintain your core business.

That's already a very good result.

After all, it's quite an amazing thing that all four of them are constantly improving.

This has been the case for many years. You have to stop at some points; you can't keep going up forever, and the age curve of athletes doesn't allow it either.

fifth.

Xie Zhengye.

He ran 9.90 seconds here.

Judging from the situation, if it weren't for the 9.90-second speed barrier stopping him, he could very well have rushed ahead even further.

The details of this era, even on the original timeline, are full of vigor and high spirits.

After all, back in the country, his nickname at that time was...

Record King.

Breaking records during this period was as easy as walking on flat ground.

Not to mention on this timeline.

谢正业不仅200米追平了苏神创造的19秒65的亚洲纪录，100米更是冲到了9秒90上。如果能够再进一步，在这个时间线上它很有可能达到9.80+的水平。

It's even possible that the peak performance could be even higher.

He was healthy, and he had never suffered a fatal injury.

Su Shen scientifically developed his potential from a young age.

They deserve this title.

Moreover, because he has consistently won, improved, and grown, never stopping, Xie Zhengye's vigor on this timeline is remarkable...

It's many times larger than the original timeline.

It is said that youthful spirit is a non-renewable resource.

Every bit worn away reduces the amount available.

The current Xie Zhengye.

Just ...

Not a single bit less.

And even more and more.

They haven't reached their commanding heights yet.

Sixth, Liang Jiahong.

9.99.

The seventh Xuzhou prefecture...

9.99!

Upon seeing this result, Xu Zhou immediately jumped up from his spot and began punching the air incessantly.

Although this result was achieved with the help of wind speed.

They made use of the mountainous terrain.

It can be said that it has all the buffs.

but.

No matter how many buffs you get, whether you can break through this limit is a question.

If the speed barrier cannot be broken.

Then the 10-second barrier will completely trap you.

No matter how high the buff you get, you still can't get past it.

Use these advantages to push your limits and let your body adapt to those limits...

That's the advantage that Su Shen most wants everyone to have right now.

Instead of living like the ordinary life next door.

Always strive with high-achieving results in mind.

It looks glamorous.

As a result, he underperformed in every major competition.

It's normal for it to drop a few levels.

Even a drop of 0.1 is considered an excellent performance.

This has never happened before in China.

Not before.

There won’t be any in the future.

Only Zhou Bing's score was 10.05.

However, he only runs 200 meters; the 100-meter dash is usually used as an auxiliary means to support the 200-meter dash.

He was actually very happy to achieve such a result, because he had already achieved his ultimate goal.

That is to break the 20-second barrier.

He had already done that a long time ago.

Therefore, he doesn't have as much obsession with the 100-meter dash.

On the contrary, they did it with great ease.

It was done with ease and practice.

We were able to travel light.

Steady progress.

When the final results came out, many people were surprised.

Even Yang Jian couldn't help but keep praising it:

"Only one player failed to open the 10-second window."

"Seven players who broke the ten mark."

"Coach Li, did you see that?"

"Seven players broke ten points."

"Coach Li?"

Li Tao had long since lost track of time.

The results were displayed on the large electronic screen.

My eyes had long since become blurry.

The scene that his master longed to see but could never witness.

I never imagined that I would witness this in my own generation.

Unexpectedly, several decades have passed.

I saw it myself.

Almost everyone lasted ten seconds.

Just look at this lineup.

This level.

Can they stand up to Emilia head-on?

Can we take on Jamaica head-on?
Answer.

It's already self-evident.

It's all written on the screens in Qing Tang City.
