The Su God of the Reopening of the Sports Arena

Chapter 2253: Connecting the Acceleration Zone! A Faster Acceleration is Born!

"he……"

"What did he do?"

"Impossible... This is impossible."

"How can he switch so quickly?"

This is no longer what a coach thinks.

Almost all coaches think so.

Even Mills.

At this moment, I felt that my eyes were shocked when I looked at it.

Another impossible thing.

So in Mills's opinion, he didn't know how this should be done.

He even thought that this was not something that athletes of this century could do.

The results of it?
What did you see in the end?

There was an athlete right under his nose.

The transformation of startup and acceleration.

Make it flow smoothly.

Or.

This is the scenario Mills fantasizes about.

The reason why he used illusions was because he himself knew...

I don’t know how to get athletes to do this in my entire life.

Because he felt it was simply impossible to do.

He has no confidence in himself.

He doesn't have this confidence in athletes either.

At least while he was alive.

He thought he was invisible.

and then?
It's this Oriental guy again.

It's this Su again.

Again and again.

Did this.

Another impossible thing.

Made it possible.

"Okay!"

When Randy saw this, he couldn't help but slap his thigh.

Because now it has been done.

Indeed, even himself.

I don’t know how to do it.

In this regard, he actually has similar ideas to Mills.

He originally thought it was impossible.

The results of it?
Someone just did it.

And it’s done so smoothly.

What feeling does it give people?

It's like you suddenly switched from a 30fps phone to a 60fps one.

This feeling cannot be understood by those who have never seen it.

"So that's it..."

Ralph Mann's voice was not as loud.

But you see the enthusiasm in his eyes.

But it hasn't diminished at all.

Even better than Randy next to him.

Even more vigorous.

In fact, as a member of the coaching team, he did not recommend Su Shen to always use himself as a guinea pig.

After all, athletes’ youth is precious.

He was also an athlete.

Of course I know it very well.

So even if he had this selfish motive, he never spoke out.

The results of it?
Every time, they take the initiative to do it.

And the key is that they can do it every time.

In this situation, Ralph Mann's heart could no longer hold back the throbbing.

I must cooperate with Su.

except him.

No one can satisfy his appetite.

Yes, none of them anymore.

Even that Bolt.

This was the thing he most wanted to make into a human specimen.

Now it has been forgotten.

If I were to exchange with Su.

Then he definitely won't change.

Optimizing stress conduction at the Achilles tendon-muscle interface!
The Achilles tendon is the thickest tendon in the human body, with a diameter of about 1.5 cm and an elastic modulus of about 1.3 GPa, which directly affects the energy transfer efficiency.

At the peak of Su Shen's extension in the seventh step, the Achilles tendon was subjected to a tension of more than 2500N and produced a deformation of 8mm!

at this time.

The wrinkled structure of the gastrocnemius muscle fiber ends at the muscle-tendon junction increases the fold angle from 12° to 18°.

Increasing the contact area will improve the uniformity of stress distribution and avoid micro-damage caused by local stress concentration.

The initial tension generated by pre-activation causes the collagen fibers to change from a disordered spiral state to a parallel arrangement, and the elastic modulus is temporarily increased to 1.6 GPa.

But this force is so strong!
How can you possibly be in complete control?

If you can't control it.

What's the use?

This was Mills' final struggle.

Indeed, as a 100m sprinter.

If you only run fast in a certain section, it's useless.

Even if your behavior delays the entire 100-meter performance, that would be picking up sesame seeds and losing watermelons.

The movement in front becomes so smooth, the impact it brings and the acceleration of the whole body forward feel completely different from before.

Don't say it's so smooth.

Every smooth frame.

The energy consumption and control that the body needs to deal with will increase exponentially.

Therefore, Mills believes that it is difficult for Su Shen to control this conversion speed that is like a runaway horse.

Of course, it was also his last attempt to save his reputation.

If this step has been done.

That’s a real breakthrough.

That's a breakthrough method that no athlete knows.

There is no way to break through that any coach knows.

That's something completely new.

And for now.

If it can be used.

Even if it is successful.

There is no doubt about that.

It’s a new thing developed by the laboratory on Ersha Island.

They will directly crush North America in the sports science system.

Even crushed the entire blue planet.

Can you do it?

of course can.

Su Shen had anticipated such difficulties.

How could it not be expected?
Faced with a sudden surge in impact.

The knee joint angle increased from the traditional 145° to 150°.

Reduce the angle between the force direction of your quadriceps and the long axis of the femur from 35° to 30°.

This suddenly creates a unique "torque lever" effect.

Next is patellofemoral joint stress optimization.

The sliding angle of the patellar track in the femoral trochlear groove was adjusted from 22° to 18°.

The patellofemoral contact area increased by 15%, from 2.8 cm to 3.2 cm.

The contact stress is reduced by 23%, from 12MPa to 9.2MPa, avoiding cartilage wear.

Dynamic adjustment of the quadriceps moment arm.

By activating the oblique head of the vastus medialis muscle 20 ms in advance, the patella was displaced 1.2 mm medially, and the distance between the combined force line of the quadriceps femoris and the knee rotation axis increased from 5.8 cm to 6.2 cm.

The extension torque is increased from 125N·m to 134N·m.

What does this mean?
Of course, this is done to light up the acceleration step of promoting the start of conversion...

Mechanical singularity!

Just by making these adjustments the magic happened.

It was as if a singularity had really been activated.

It made all his energy suddenly flow through.

Not stuck at all.

This is a smooth and flowing route.

Let Su Shen’s impact be even stronger.

Can withstand it.

It can also be transformed!
Then we saw that when Suarez’s knee joint was extended to 150°, the angle between his femur and tibia forced the hip joint to passively move backward 0.05m.

Forming a coupling mechanism of "knee push-hip pull".

The semimembranosus and semitendinosus muscles contract eccentrically in the late stage of knee extension, 50ms before leaving the ground, generating a knee flexion moment of 300N·m.

Forms a "force couple" with the quadriceps.

Converts linear knee thrust into rotational torque at the hip joint.

Combined with the 125° neck-shaft angle, the force direction of the gluteus medius forms an 18° angle with the femoral neck axis.

When the hip joint moves backward, an additional horizontal force of about 150N is generated, which is equivalent to a 7% increase in propulsion force based on the traditional ground-pushing force.

Thus.

The whole transformation.

Completely done.

Su Shen's whole feeling...

It was as if someone had dropped a bomb inside of him.

This step requires more attention, energy and physical energy to make the transformation.

to switch the zone field between start and acceleration.

This is a very important thing.

Even the so-called seamless connection in the past.

In fact, let's look at it under a scientific microscope.

There are still a lot of seams.

until today.

Only then can it be truly put under a scientific microscope.

It's not a big problem.

Su Shen's move forward has actually pulled everyone away.

Never mind if you're Powell or Carter.

Never mind if you're Bolt or anyone else.

Now they are all the same in Su Shen's eyes.

fast……

It’s too fast, how could it be so fast?

How did he do this just now?
Why so fast?
Carter learned a lot from Su Shen's videos, which led him to focus more on Su Shen's skills than anyone else.

He studied Su Shen's movements more carefully than anyone else.

I thought I had learned the truth.

As long as you continue to participate in training, there is a chance that you can break the 1.80 threshold.

Even further.

He didn’t dare to think about opening it at 1.70 like Su Shen did.

But open 1.80.

He thought he still had some chance.

Therefore, he watched Su Shen's running more carefully than anyone else, even though he was now a part of the game.

It was fine at the beginning, as Su Shen was familiar with the rhythm and routine operations.

It looks very exciting, but it was indeed within Carter's expectations.

Continue until step 7.

This is the moment when the 7th step is taken.

Carterton felt that the person in front of him seemed to have suddenly changed gears.

The speed increased immediately.

Of course, if you want to be more serious, it’s not that the speed has increased by one section, it’s just because the other people are switching places…

There will be a noticeable changeover time.

This is true no matter who you are.

There is no difference.

Especially under the current American track and field-dominated system, no one can solve it.

Even Bolt is no different.

It is said to be God’s startup acceleration, but conversion is also required here.

There is no one who does not need to convert.

Of course, Su Shen also needs to transform, but compared to the transformation speed and time of others...

This move he just made.

It's like there's no transition time.

It goes straight from starting to accelerating.

There were no signs at all.

This is simply not the modern American system and can be fixed.

Otherwise it wouldn't be so shocking.

original……

This is what extreme conversion feels like.

I felt the smoothness brought by step 7.

immediately.

Su Shen continued with this feeling.

Because once any feeling comes out, if you don’t continue with it, it will come to an abrupt end.

Sprinting is a continuous thing.

There is no continuity.

Your skills will mean nothing.

This is why Mills thought so just now.

Unfortunately, all of them are at the seventh mechanical singularity that Su Shen had just established.

It was completely blown up.

Instead it was Su Shen himself.

The eyes are bright.

The steps are very clever.

Start entering the acceleration zone.

From the "torque lever" model of the quadriceps-knee joint, to vector decomposition and joint dynamics reconstruction.

And then it’s now.

Relying on the support of the mechanical singularity, it is the first one among all people to enter the acceleration position seamlessly.

Since we have just started, we rely on the ankle joint and the soleus muscle of the calf.

Then.

Officially entering the acceleration phase from conversion.

Su Shen.

Still gave his own answer.

That is……

Rely on your strongest muscle.

Gluteus maximus inheritance.

Three-dimensional torque integration of the hip-core power hub!
Bang bang bang bang bang.

Full range control from sagittal to frontal plane!
Bang bang bang bang bang.

Use the gluteus maximus as the starting point for the transition.

This is because the gluteus maximus fibers are distributed in multiple directions, with the upper bundle slanting upward and outward, the middle bundle being horizontal, and the lower bundle slanting downward and inward. When the hip joint is in 95° flexion position, the upper bundle fibers contract to generate extension torque and external rotation torque, counteracting the internal rotation trend caused by the forward tilt of the trunk.

When the lower bundle of fibers contracts, it generates an adduction torque, which cooperates with the contralateral gluteus medius muscle to control the lateral deviation within ±1.2°.

In this way, the order of muscle fiber recruitment can be optimized, with the lower bundle activated before the upper bundle, so that the angle between the direction of the combined force of the gluteus maximus and the vertical line of the ground is reduced from 25° to 20°!

The proportion of horizontal force increased from 45% to 53%!

The propulsion force contributed by a single muscle is about 320N!!!

Twenty meters.

Su Shen felt like he was riding a bicycle on a downhill slope.

What we need to do now is not to worry about the power problem.

Rather it is a question of how to control it.

It can be controlled.

this speed.

It’s already ridiculously strong.

Bang bang bang bang bang.

The speed is getting faster and faster.

There is no speed consumed by starting and accelerating conversions.

It's just horror.

Most people who do this are courting death.

When you were a kid, you rode a bicycle downhill. When the speed reached a certain limit, your whole body would shake violently, which means that the speed was beyond your body's control.

Even if you ride the bike harder, you won't speed up, but the shaking will get worse.

The same is true for the human body.

At this time, the limit rate for initiating conversion is lost.

Su Shen accelerated a little too fast.

Ordinary people simply don't.

Can't stand it.

Can’t stand it?
Sorry.

Buddy, this life.

You are not an ordinary person anymore.

The "dynamic stiffening" mechanism of the core muscles!
Su Shen has been reopened for so many years.

Everything is prepared in advance.

Plan ahead.

Nothing is left out!
It's hard for you to control, isn't it?

Nothing.

Su Shen immediately mobilized his core muscles and built a three-dimensional stable structure through the three-layer muscle system!

The deep stabilization layer - the transverse abdominal muscle adopts the "waist tightening" mode, with an electromyographic amplitude of 400μV. It increases the intra-abdominal pressure to 80mmHg through the tension of the aponeurosis, increases the trunk stiffness by 40%, and reduces energy leakage during extension.

The middle power layer - the internal and external oblique muscles generate anti-rotation torque with an activation ratio of 3:2. The left external oblique muscle and the right internal oblique muscle contract synergistically to form a torque of 25N·m in the frontal plane to offset the lateral wind force. The wind speed of 0.8m/s generates a lateral force of 0.12N, which is combined with the inertial deviation.

The surface dynamic layer - the erector spinae and rectus abdominis form an "anteroposterior tension chain", which produces an anti-flexion moment of 182 N·m in the sagittal plane, maintains a 60° forward trunk tilt posture, and makes the horizontal component of gravity 608N and the horizontal component of the support reaction force 1845N form a net propulsion force of 1237N.

Take a look.

Just ask you if you are afraid.

What is stable or not?
Here with me.

Give me stability.

As steady as a diamond!

Solid as a rock!

Lao Yi, who was standing behind, was stunned.

I rely on.

Mr. Su.

There are even hidden goods.

No.

You have to extort money.

This one.

Just my taste.

Everyone now...

They all mistook Su Shen for Duobao Taoist.

Absolutely.

Everyone who sees it wants...

Take a bite.

Twenty-five meters!

Preparation of neural control algorithms for multi-joint kinetic chains.

From spinal cord pattern generators to predictive programming of the brain.

The temporal coding in the spinal cord centers is turned on.

The interneuron network in the lumbar sacral segment of the spinal cord generates a stereotyped pattern of three-joint extension through the temporal superposition of crossed extensor reflexes and flexor withdrawal reflexes.

Hip extension command: initiated by the extensor motor neuron pool of the L5-S1 segment, triggered 20ms after landing and lasting 80ms.

Knee extension command: activated by the L3-L4 segment with a delay of 30ms, overlapping with the hip joint command by 50ms, forming a torque superposition.

踝关节跖屈指令：由S1-S2节段在离地前40ms爆发性发放，动作电位频率从50Hz跃升至150Hz，实现“末端爆发“效应。

Then, through the hard-coded mode of "terminal burst" at the spinal cord level, the timing error of the three-joint extension is controlled within ±5ms, ensuring the accurate superposition of the force-time curve.

Thirty meters.

Su Shen’s speed is already super-penetrating.

this speed.

This acceleration feels so much better than before.

But he wanted to go faster.

Because this way you can run along the way.

Also achieved a breakthrough in inertia!

It’s like eating two fishes with one stone, or even… three fishes with one stone!!!
The gluteus maximus muscle segments adopt a mixed series-parallel arrangement. During high-speed contraction, the series muscle segments are arranged along the long axis of the muscle, responsible for rapid shortening, and directly generate thrust through the "power stroke" of the myosin head.

Then it enters the parallel myometrium, arranged perpendicular to the tendon, and generates lateral tension through the cross-bridge circulation to maintain the stability of the muscle fiber morphology and prevent energy dissipation caused by excessive stretching of the series myometrium.

Take control.

Take control.

look up.

Enter the run on the way!
And this time.

Within Su Shen’s gaze.

There is no one at all.

No one.

Even.

The sound of spikes.

They are all so small.

Any small one is fine.

can be ignored.
