The Su God of the Reopening of the Sports Arena

Chapter 2254: A completely opposite approach to the Su Shen system! Using technology to drive the body?
Su Shen took the lead.

Pulled everyone away.

Even Bolt.

Here.

Didn't gain any advantage either.

Bolt is simply...

Greatly disappointed.

Because he knew very well what his current situation was.

He is definitely in great shape.

Otherwise, how do you think they achieved such outstanding results in so many competitions?
I originally thought it was like this.

Even if I met Su.

There is also a fighting force ahead.

It won't be so embarrassing.

He knew that it was impossible for him to beat Su Shen if he started.

Ever since Su Shen opened the 1.70 limit, he knew that this was something he could never achieve.

In this case, this segment can be considered abandoned.

Just try not to be too exaggerated.

But you can't lose in the acceleration segment.

At least there is an advantage before acceleration.

It looked like this before.

can.

Before is before.

This is now.

Anything you can imagine.

They must be able to withstand the test of reality.

If it can't stand the test in reality.

Then this imagination is called fantasy.

just now.

That's how Bolt feels.

He felt himself before.

Or the estimate is too optimistic.

I still underestimated this guy.

Or so to speak.

He seems to have been...

They are all underestimated.

From the first time I met him, every time he thought something was impossible to do and every time he thought it was impossible to break through, he would break through it again and again.

He initially thought it was his own problem.

But even Mills couldn't have predicted what happened next.

Something that even Mills thought was impossible.

He can still do it.

That's it.

Exceeded Bolt's cognitive limit.

Because Bolt knows very well that he cannot compare with Mills in terms of cognition.

That's why he trusts Mills so much.

The feedback I gave him before I met him was always very good.

There is almost no misjudgment.

Overcome all obstacles along the way until you reach the top of the world.

Become black lightning.

until.

Met him.

However, at the beginning, there was a big gap in strength.

Bolt didn't think there was anything wrong with this.

Mills had no such idea.

I just feel that Su Shen can always do something unexpected.

But that's about it.

Because the gap in strength is so huge, what does it matter even if something unexpected happens?

No threat to Bolt.

There's no need to think about it any more.

Otherwise, if you consider everything, you will not be able to bear it and you will not have enough energy and time to do so.

Unless it can be confirmed from the beginning that Su Shen can achieve this state.

But how is this possible?
Because it was during this era when Su Shen rose to power.

However, the champions of the entire Asia are just cannon fodder in the international arena.

How could you expect Mills and the others to be interested in a cannon fodder?

Even for Su Shen in the original timeline, it was not until 21 years that he truly shocked the world.

He truly became a world-class general.

and so.

You can't blame Mills, they weren't prepared.

Because there is no one in that timeline.

Would be interested in an Asian sprinter.

Until Su Shen got closer and closer to Bolt.

Su Shen continued to make breakthroughs, breakthroughs, and breakthroughs.

Finally starting to get close to Bolt.

Bolt and Mills really recognize this guy...

It seems different from other Oriental athletes.

It doesn't seem to be simple.

But even so, it is still not as if we are facing a formidable enemy.

The reason is very simple. Even in 2011, Su Shen won the first -meter gold medal in a major competition in the history of the yellow race.

This problem has not been fixed.

Just like Bolt said.

If he plays.

There was no false start.

That wave.

There is no way I can lose.

The championship will not fall into the hands of others.

So even when Suarez won the 2011 Daegu World Championships, it did not change this view.

The real transformation happened...last year.

Last year in London, Suarez defeated Bolt head-on.

In the Olympic final, he took away Bolt's gold medal and broke Bolt's previously held Olympic 100-meter record.

From this moment on.

Bolt is the one who truly regards Suarez as his opponent.

An opponent who requires you to do your best.

Bolt thought so.

Mills thought so too.

Then last year Mills reviewed the game again and was surprised to find that... in fact, Su had started to take an unconventional approach from a very early stage.

It's just that at that time Bolt was too high and the gap was too big, so Mills didn't realize the problem at all.

Looking at it now, Su Shen is facing a bottleneck in speed.

almost.

Never stopped.

This is a horrible thing.

The deeper you dig, the more terrifying it becomes.

Because even if it is Mills, if you don't give him a talented player like Bolt or Blake, an ordinary Jamaican master, the best he can do is to break 10 or 9.90.

That's it.

If you want to say that you can do this to a player like Su Shen who didn't seem to have much potential before...

Keep breaking through from the low level.

Has always been a threat to Bolt.

Then him.

I definitely don't have that confidence.

at this time.

I only realized it when I looked back.

How scary is this guy?

And he shows up every time.

This is real.

Mills has discovered this pattern.

Every time it appears.

No matter he wins or loses.

He will be stronger next time.

This is simply...

Mills thought about it for a long time and finally came up with a corresponding feeling.

Just like the comics that are popular in Europe and the United States now.

This is simply the Saiyan physique.

correct.

At least that was the only word he could come up with now.

Bolt and Su Shen started fighting.

Bolt felt a little pressure as he was left behind and didn't catch up with anything in the acceleration zone.

But his four consecutive games with a time of under 4 seconds is no joke.

Still have absolute confidence.

Very strong.

But Sue.

Just like this...

You can't beat me!
Bolt also broke out.

In other words, he was angered by Su Shen's performance.

Bolt also opened up.

If he doesn't start big, if he loses too much in the beginning, he will be under too much pressure later.

At this time, Carter and Old Bao were still in front.

But it won't last long.

Carter is shorter in height, so the air resistance he encounters during acceleration is relatively small. But he still uses technical moves to further reduce air resistance.

In the acceleration zone, his torso forward tilt angle quickly reaches 40°-45° after the start and remains stable, and his head, spine and lower limbs form a relatively smooth streamline.

At the same time, his arm swings compactly, with a moderate arm swing height and a swing trajectory close to the body midline, which reduces the generation of air turbulence. This optimization of aerodynamics allows him to use more energy for body propulsion during acceleration.

As for Lao Bao, due to his height, he faces greater air resistance during acceleration. To overcome this problem, he pays special attention to adjusting his torso posture in the acceleration zone.

For example, in this shot, after starting, the forward tilt angle of his torso will gradually transition from 50° to 35°. Through this gradual forward tilt change, the windward area of ​​the body is reduced.

In addition, his arms swing with a large amplitude, but the swing frequency is highly consistent with the step frequency of his lower limbs.

This is to use the reaction force generated by the swing of the arms to balance the body and disrupt the air flow field to a certain extent, reducing the hindrance of air resistance to the body's forward movement.

Powell's energy metabolism characteristics match his technical style.

Although his step frequency in the acceleration zone is lower than Carter's, fortunately, he can burst out a large amount of force output every time he pushes and stretches, so his energy consumption is concentrated in the single push and stretch process.

His aerobic metabolic system begins to supply energy synergistically in the early stages of acceleration. In the 30-meter acceleration zone, the aerobic metabolic energy supply ratio can reach about 25%, which helps to maintain a relatively stable energy supply and avoid premature exhaustion of the phosphagen system.

Bao has a higher density of mitochondria in his muscles, especially in his gluteus maximus and quadriceps, which allows him to use oxygen more efficiently to generate energy and provide support for sustained high-intensity stretching.

Carter still has a starting advantage in front of him.

But enter the acceleration zone.

Suddenly there is no advantage at all.

At least not much when facing Lao Bao.

It can be seen that Powell's neuromuscular control focuses more on the regulation of hip joint-related muscles.

During acceleration, his cerebral cortex activated the gluteus maximus and hamstrings more strongly and persistently.

During extension, neural signals prioritize ensuring that the hip joint is fully extended to take advantage of its limb leverage.

His proprioceptive feedback system is also more sensitive than Carter's. In the acceleration zone, he can fine-tune the force angle and strength of the hip and knee joints in real time according to the ground reaction force and body posture.

Ensure that power output is always in the direction that is most conducive to propulsion, and make full use of the advantages of its body structure to achieve efficient acceleration.

Old Bao still has some skills.

not simple.

Worthy of being the previous world record holder.

No ability.

Can't do this.

at this point.

Carter can't compare.

Whether it's talent or physiology.

There are gaps.

Even at the beginning of the acceleration zone, Carter showed extremely strong neuromuscular recruitment efficiency, and his spinal central pattern generator was able to quickly activate the lower limb muscles.

In the first five steps after the start, his nerve impulses were conducted about 5% faster than Powell's, allowing his muscles to respond more quickly to the need for force.

During the extension phase, the motor cortex's control over the knee extensors is also extremely accurate.

It can accurately control the intensity and timing of muscle contraction to achieve rapid extension of the knee joint.

This efficient neural control enables him to achieve a higher stride frequency in a short period of time and quickly establish a speed advantage in the early acceleration zone.

but……

That is the early advantage.

It’s not far into the acceleration zone.

It's just not good enough.

That's the gap itself.

Although Powell's hip-dominated acceleration mode is relatively efficient, it puts a greater load on the muscles around the hip and knee joints. This results in greater stress on his gluteus maximus and quadriceps than Carter in the acceleration zone, and more obvious muscle soreness in these areas at 30 meters.

But people are not stupid and do it to relieve fatigue.

During the acceleration process, he will fine-tune the joint angles and use the elastic potential energy of the muscles to assist in exerting force and reduce the intensity of active contraction.

In addition, he will perform targeted joint stability training and fascia relaxation during training to enhance the joints' tolerance to high-intensity loads and delay the onset of fatigue.

Sprinted to the back.

It's a contest of talent, understanding and technology.

Although Carter had some understanding before, in terms of overall technique.

In fact, he is not as good as Powell now.

Especially the acceleration zone. Lao Bao is really...

Extremely strong.

Otherwise, he would not have been able to become one of the strongest athletes in human history like Bolt.

You have to know that his physical talent is not as good as Bolt's.

This was possible because of his technical skills in this area.

Do better.

People who have achieved this level really don't have good skills.

Among the Five Tigers, the only one with poor skills...

Guess who it is?

It was none other than Bolt.

As for the rest of the people, Green would name them and say that they have poor skills.

In fact, among the five tigers, the one who relies more on physical talent to run is Bolt.

This is also why Green always feels that he is a bit of a waste when looking at him.

It's because of Bolt's skills compared to his physical talents.

Still not good enough.

Especially Powell in this timeline, because he introduced some theoretical knowledge provided by Su Shen that was far ahead of the times, especially the blessing of black technology.

This has made his health level, training quality and training cycle much better than before.

That puts him in better shape.

Higher training quality and longer training cycles have made his technical sense better than before.

Don’t talk about other times, just look at the acceleration zone.

Powell has been freed from Carter's entanglement.

Obviously surpassed the past.

The gap began to widen.

Powell, who walked patiently in front of him, trying to find the feeling, had better patience than at any time in his previous life.

but……

This scene didn't last long.

Because of the future master.

But it's not just Carter.

There is actually one more.

Get rid of the pervert in front.

That future is beyond the gods.

There is one more thing that cannot be ignored.

That's when we start to exert our strength...

Usain Bolt.

That’s right, who says Bolt isn’t a promising talent?
In fact, Bolt is.

He is an absolute up-and-coming expert.

You could say his starting ability is limited by his height and huge inertia, and is naturally insufficient.

It is difficult to reach the top in history.

But other than that.

Bolt's acceleration ability.

Bolt's mid-distance running ability.

In other words, apart from the start, there are 5 remaining sections in the future.

Every.

Bolt is very strong.

All outstanding.

They are all terrifying.

This.

That's why he is obviously a super tall guy with a height of over 1 meters.

But it will appear on the list of the strongest prospects ever in human history.

This doesn't make sense no matter how you look at it.

It's because he started it.

The remaining each forward segment.

They are all terrifyingly powerful.

He in this timeline.

Needless to say.

Don't look at Carter who has passed him.

But that's just the start.

Carter is shorter and has a lower center of gravity, so he has better physiological conditions for starting.

In addition, Carter also learned a lot from Su Shen's straight-arm starting feeling in this life.

I have turned myself into an advanced version of Su Shen in 18.

Only then can you nod in front.

otherwise.

Although he is also a member of the 9.70+ club.

But in fact, even they are all in the 9.70+ club.

Carter's strength is also ranked at the bottom of the club.

Not to mention.

This is a battle between giants.

This is blitzkrieg.

Is 9.70+ strong?
Very strong.

But you are still invited to sit at the children's table.

This table is for adults.

It's not your turn to sit.

Bolt started to exert his strength.

He would soon make it clear to the whole world.

Su Shen will soon understand.

Why is he called Nulibo this year?

It's not just that he is more self-disciplined, trains harder, and doesn't skip training classes anymore.

Just a little.

Mills told him.

Principle of energy transfer efficiency-joint angle determines the transmission of power chain.

Maybe Mills doesn't know as much as Su Shen, the restarter, but compared to the others, he has enough depth.

He knew Bolt didn't understand, but he didn't intend for Bolt to understand.

He just needs Bolt to do his job well.

Why do you say that?
Because Mills knows...

The essence of sprinting is that the joint angles are the "gear meshing points" of the power chain during the efficient transfer of human kinetic energy.

So he made the following arrangements for Bolt.

It is still based on the three-joint torque drive rate technology system.

One of the keys is the storage and release of elastic potential energy.

Muscle-tendon units such as the Achilles tendon are stretched and store energy during the joint buffering period when the knee is flexed ≤40° when landing. If the knee is flexed >40° → the tendon is not stretched enough → elastic potential energy↓ → energy release efficiency in the extension phase↓.

Secondly, his experience made him discover one thing:
Bolt's extension angle is 90°-100° at the knee + -15° at the hip, which allows the quadriceps-patellar tendon-tibia to form a straight force arm - angle deviation → force line offset → component force loss.

If the knee is <90°, the quadriceps muscle arm is shortened by 30%.

he does not know.

What he is talking about now is actually the professional terminology that will be formed in the future——

Joint Alignment.

Translated, it is called joint coaxial alignment.

If these two are done well, the power chain transmission will be reopened, making the energy transfer smoother.

This is why it is said that joint angles determine the transmission of power in the chain.

Once these are done, you can proceed to the next step.

That is...

In the acceleration zone he asked Bolt to adopt a new mode.

Use the joint angle to directly change the muscle torque, that is, Torque = muscle strength × lever arm.

This threshold is used to impact the "critical point" of the torque peak area.

Just like Bolt's steps, the hip joint pushes back and the angle threshold is adjusted to ≥-15°.

The mechanics of this step are based on the fact that the gluteus maximus moment arm peaks at -15° hip extension, with the moment arm length ↑30% vs 0°.

Then the knee joint is extended, and the angle threshold is adjusted to 90°-100°. In this interval, the quadriceps muscle moment arm is the largest, and the moment arm is shortened by 110% when the knee is flexed>50°.

Then comes the ankle joint.

Dorsiflexion was adjusted to ≥10°.

Use the tibialis anterior muscle to pre-stretch → activate the stretch reflex → increase the gastrocnemius contraction force by 15% when digging the ground.

This is the so-called kinematic Komi PV elastic enhancement effect.

Changing to a smooth picture is——

When ankle dorsiflexion is less than 10° → the foot touches down ahead of the center of gravity → braking force is generated.

That's this moment.

The horizontal component of the ground reaction force is backward.

Then use the stretch reflex threshold to maximize muscle spindle sensitivity at a specific stretch length.

For example, Bolt now, the frequency of muscle spindle discharge of the hamstring muscle increases when the hip is flexed 70° → the hip is flexed quickly and the leg is swung at the end of the stance.

The joint capsule mechanoreceptors then trigger feedback at the angle threshold point.

Such as knee flexion 40°.

Combined together, it is -

Knee flexion > 40° → receptor signal ↑ → spinal cord inhibits quadriceps contraction → excessive buffering → delayed extension.

100ms before Bolt's foot strikes the ground in the acceleration zone, the central nervous system pre-adjusts muscle stiffness based on the expected joint angle, such as 10° ankle dorsiflexion.

Because the angle is not up to standard → insufficient pre-activation → joint stability when landing↓ → energy leakage.

Although Mills' entire system feels rather fragmented.

But you can't help but say that the experience he summarized is not good.

He just doesn't have a concept that holds together a whole.

Perhaps he didn't know that his future would be defined as -

Neural control principle: Kinematic angle threshold triggers reflexive force.

But he just didn't know the name of this integration.

After all, this set is not available now.

It is an applied science system that can be directly used in sprinting that was formed through the trial and error of countless famous teachers and coaches like him.

Stance phase knee angle dynamics can then start working online simultaneously.

Because from the perspective of complex systems, the joint angle threshold is the boundary of the phase transition of the action mode.

Want to trigger stance phase knee angle dynamics.

Bolt's acceleration zone requires knee flexion ≤ 40°:

The system is in a rigid lever phase, which is equivalent to improving efficient energy transfer.

Knee flexion >40°:

The system transitions to the damping buffer phase.

It is equivalent to controlling energy dissipation.

This is actually the dynamic systems theory of the future.

Because the threshold is the critical point of phase transition.

If Su Shen were to help him summarize, Mills made the following points:

1. Energy transfer: ensure the efficiency of elastic potential energy storage → release, which is consistent with the tendon spring model.

2. Mechanical lever: maximize muscle torque output, adopting the mode of lever arm length × muscle strength.

3. Neural control: It matches the stretch reflex peak and movement timing, which is the muscle spindle-gamma loop.

4. System stability: Maintain phase boundaries during high-speed motion.

The whole set.

It is what he said, that the joint angle determines the transmission of the power chain.

If Jamaica had a laboratory like Su Shen's, they would definitely find that if this method is successful, in theory, the athlete's joint angle can be within the threshold range, and the mechanical work output can be 2.1 times higher than that of athletes who do not know how to do it.

And muscle oxygen consumption is 35% lower.

This is direct evidence of the optimization of the threshold angle.

However, it would take many years for this news to be released in the biomechanics academic journal "JOURNAL OF BIOMECHANICS", which is "Journal of Applied Biomechanics".

Now except Su Shen himself.

No one knows what his name will be after integration?
In fact, many things are gained through experience first, and then gradually pieced together to form an overall system.

What Mills did fits this profile perfectly.

Perhaps he does not have such a holistic technical theory as Su Shen.

But in this day and age.

He is still a strong man standing on the top.

Otherwise, Bolt would not be convinced.

Countless sprinters flocked to it.

With the support of such scientific theories.

Bolt finally exploded with his technical energy.

Try hard, but what are you trying for?

Self-discipline, self-discipline, self-discipline for what?

Do you think this is simply hard work? Improvement will, of course, be reflected in specific things.

it's here.

Mills wants Bolt to have more technical skills so as to stimulate his already invincible physical talent.

Bolt's physical talent was so strong in the past that he didn't need so much technical sense to do this.

But now we have a powerful enemy, Su Shen.

The original sense of technology alone is no longer enough.

Therefore, Mills did not focus too much on the physical aspect.

Instead, Bolt was modified technically.

If you look higher, you will find that -

Su Shen pays more attention to the body, starting from the body and using the body to drive the technique.

Whether it is reopening or giving it to the rest of the domestic athletes, the emphasis is on physical training first.

This is because our physical talents are poorly developed and very unscientific.

Bolt's physical talent has already exploded.

If you continue to focus on physical talents, the effect and marginal effect will not be high.

Therefore, Mills teaches students in accordance with their aptitude and analyzes specific problems specifically.

The approach taken was completely different from that of the Su Shen system.

And the effect.

You will know soon.
