Su Shen made the final adjustment on the runway.

On the track, he was like a focused scientist, not a runner.

Silently adjusting his breathing.

His last step was sorted out in his mind like playing a precision video, and every link was crucial.

For athletes, adjusting breathing and controlling the rhythm is the key, especially paying attention to stimulating the olfactory nerve endings in the nasal cavity. During the preparation stage, the body has not yet consumed a large amount of long-distance activities. At this time, breathing through the nose is enough to maintain the body's balance.

This involves the control of the inhaler muscle, just like starting a precision instrument switch, the diaphragm, central tendon of the diaphragm and the inhaler muscles in the ribs, must be prepared. They work together to provide sufficient oxygen support for the upcoming high-intensity exercise.

You should know that after a high-intensity breakthrough exercise, relying solely on rest and adjustments after the game is far from enough. The breathing method in exercise is the core point of the entire exercise process and is also the most difficult part to master. Scientific research shows that the correct breathing method can ensure the efficient intake of oxygen and the smooth discharge of carbon dioxide, so that the muscles can obtain sufficient energy supply and reduce the accumulation of fatigue substances.

For example, good operation of the diaphragm can increase the volume of the chest cavity, allow the lungs to fully expand, and inhale more air; the accurate control of the inhalation muscle can adjust the frequency and depth of breathing and adapt to the needs of different exercise intensity. These professional breathing skills are the key to athletes' performance and avoid injuries, which is why Su Shen attaches so much importance to it.

In order to do this shot well, he had no choice but to be perfect.

It’s not because the breakthrough of the last shot has had a lot of impact on him. With his current physical condition and physical reserves, no one knows what level he has reached, only he understands it himself.

He is preparing so seriously and adjusting his breathing state so seriously, but it is actually because of the buff of this shot.

Not easy to appear.

He has used Bolt's excitement in the semi-finals to lift himself to a very strong combat state.

Usually no one can take it to this level at 60 meters.

Finally got it.

The spirit and spirit are ready.

The excitement is in place.

Then this shot cannot be wasted.

Otherwise, I don’t know when I want to play in this state next time.

Moreover, this year is also a peak in the original function of one's body. If you don't cherish it, it will be too wasteful.

He wants to be here.

Show this gun.

Shows the essence of two lives.

On the runway focused by countless eyes, Su Shen was like a silent volcano, and no one could understand the turbulence in his heart at this moment.

In the eyes of most people, he still had that familiar posture, bent his arms, ready to go, like a cheetah ready to go.

I saw his hands supporting him in front of him, and the muscle lines on his arms were tight, like a steel cable full of strength, carrying the energy that was about to explode.

His center of gravity gradually shifted to the most moderate point like a precision instrument calibration, and every trace of movement was accurate and demonstrated his ultimate control over the body.

Then, his fingers bent into an arch, like the sharp claws of a goshawk, pressing deeply into the grainy ground of the plastic track, as if he wanted to draw strength from the earth.

While doing a high-difficulty movement of physical control, breathing control is the top priority, which has suddenly increased the overall difficulty.

For perfection.

This shot.

You need to breathe and reach a new breathing point.

From a physiological perspective, breathing requires the coordinated operation of many respiratory muscle groups such as the intercostal muscles and diaphragm. At the moment of starting, it is necessary to quickly increase the volume of the chest cavity through strong contraction of the intercostal muscles and diaphragm to achieve rapid inhalation. This process is like starting a high-performance engine, which injects sufficient oxygen "fuel" into the body in an instant.

Nothing else, his shot needs fuel.

It requires a lot of fuel.

Even if it is only 60 meters.

In order to achieve the results and results he wants.

He needs to do his best.

This is a challenge to the limits of mankind and also a challenge to oneself.

call--

When exhaling, you should accurately adjust the contraction of the intercostal muscles and abdominal muscles to ensure that the breathing rhythm is perfectly matched with the body's movements, and avoid energy metabolism imbalance caused by respiratory disorders.

This fine control of breathing is like precisely controlling the accelerator and brake in a high-speed racing car, without any mistakes.

While preparing, Bolt inadvertently glanced at the left slightly.

The direction he glanced at was of course Su Shen's side.

Although Mills has told him that he has been successful in winning the tactic, he can use his shot to kill Su Shen.

Break Su Shen’s undefeated golden body at 60 meters.

But I don't know why.

He always felt that this guy was obviously plotted against by him.

But I'm always so calm.

He felt a little angry when calm.

In fact, he didn't seem to have seen Su Shen get out of control.

This made him feel inexplicably jealous.

The reason for jealousy is of course that it is difficult to achieve this level by putting himself in his shoes. I have obviously plotted on you, and you have consumed your physical strength and breakthrough. You are already at a disadvantage...

Why do you still look so calm?

Let’s talk about it.

Why are you doing so seriously?

Bolt had already noticed Su Shen's current state of concentration. No matter how you look at it, it doesn't look like a mental state that you have already fallen into a trap and should have.

It's all like this.

Do you still want to win?

Bolt was a little angry when he thought about this.

He had to give Su Shen a good look.

call--

“onyourmarks.”

call--

“ set.”

call--

At the moment when the breath ends.

Bang ————————————

The electronic gun suddenly rang out.

"The competition begins!"

Su Shen’s own heart.

The same roar was also heard.

start!

Whether it is the commentator on the scene or the commentator who is standing in front of the TV, it seems to be ignited by the same force.

He shouted at the top of his lungs.

This chapter is not over, please click on the next page to continue reading! The sound was like a surging wave, instantly breaking through the limitations of space and echoing throughout the field.

At the same time, the cheers at the scene were like a roaring awakened beast, gradually spreading from the initial overwhelming momentum, and the sound spread layer by layer until it completely covered every inch of the Birmingham indoor race, and every corner was filled with this fanatical atmosphere.

In the rising atmosphere.

Carter took the violence first.

He has been preparing for this shot for so long.

In order to let Su Shen and the whole world see it.

He has also grown up and can challenge everyone.

Carter's gun is extremely powerful and explosive.

In addition, the reaction time is only 0.138 seconds.

Ranked first among everyone.

He seems to be the first to grab the first place here.

Powell, who was also Jamaica next to him, was shocked by this activation.

So fast???

This location...

Not Sue, it's Nesta???

Powell actually started very quickly and his reaction was not slow, exceeding 0.150 and reaching 0.145.

But no matter whether it is the reaction time or the feeling of activation.

He seemed to be... inferior to Nesta Carter next to him.

Carter feels.

Start this step by yourself.

With the stimulation of this kind of competition, it has reached a height that is difficult to reach in training.

This feeling...

Stay stable!

It's definitely not bad!

Maybe it may not be possible to challenge this man.

The thought had just come out of Carter's mind.

Next second.

It should be the next zero point one second.

Carter's right hand side.

The moment someone took the first step, it was like a big bang, and started a "high-energy reaction" inside the body.

In his body, the gluteus maximus is like the command center of the army, taking the lead in starting and becoming the core engine of the entire muscle force system.

As one of the largest muscles in the human body, the gluteus maximus plays an irreplaceable role in the starting stage. It works closely with the femoral muscle and biceps to form a powerful dynamic triangle. The femoral muscle is like an accurate transmission gear, which steadily transmits strength; the biceps femoral muscle is like a high-performance piston, providing powerful boost to explosive power.

Subsequently, the extrafemoral muscle, gastrocnemius, semitendent muscle, and rectus femoral muscle are activated in sequence. They are like awakened ancient behemoths, each muscle exerting force in a specific order and rhythm under the regulation of complex nerve signals.

This series of muscle activation is not a simple sequence, but based on the principle of synergy in muscle kinema. They form an orderly chain of force around the core of the body and the buttocks.

The contraction and relaxation of each muscle is like a carefully arranged dance move, achieving perfect coordination in time and space.

The moment Su Shen kicked out, the "ripples amplitude" formed by a series of data such as bioelectric signals, muscle strength output, joint movement angle, etc., generated by his body was like a supernova explosion - suddenly violent.

This intensity is no less than the ripple amplitude generated when driving with full force in a normal and optimal state. This is a shocking display of the perfect fusion of human physical strength and sports skills.

It is the extreme shot that Su Shen wants to show.

Extreme start.

here we go again?!

Carter could feel that there was a powerful aura on his right hand and was about to erupt.

This reminded him of his own in Germany immediately.

Don't be nervous! Don't think of taking me wrong this time!

The moment the gun was fired, it was like a flash of lightning that broke through the silence. With his highly sensitive auditory system, Carter instantly activates the response mechanism of the nervous system just like a precision radar capturing the target signal.

As the nerve signal is transmitted at a millisecond speed, his muscles quickly receive instructions and forcefully kick off from the starting machine. At this time, the contraction of the leg muscles produces huge force. Through the leverage system of bones, the joints are used as the fulcrum to instantly transmit the force along the movement chain to the whole body.

The span design of this step is not arbitrary. It is based on the principle of short-term starting dynamics. The relatively small span is designed to quickly establish the initial speed and power forward in the shortest time and most stable way.

During this process, the body's center of gravity is deliberately maintained at a low position, which is based on the scientific relationship between the center of gravity and stability. Low center of gravity helps to reduce the shaking of the starting moment, ensure the stability of the starting posture, and lay a solid foundation for subsequent acceleration.

Carter is indeed stronger than before.

You can tell from his activation.

Even Old Bao.

It may not be able to withstand now.

No.

It should be said that even Lao Bao is old.

Can't stand it either.

This starts.

Too much reinforcement!

Start the step forward!

After landing, Carter's body was like a precision-tuned high-performance engine, and began to increase his power in an all-round way. Based on the principles of muscle contraction mechanics and movement energy conversion, he began to increase strides and stride frequency.

The leg muscles, especially the main muscle groups such as the quadriceps and hamstrings, undergo strong centrifugal contraction and centripetal contraction. Through the back-punching action, the stored elastic potential energy and chemical energy are efficiently converted into kinetic energy, and push the body to move forward quickly like an arrow off the string.

At the same time, as an important balance and support part in running movements, the arms are swinging forcefully according to the theory of coordinated movement between the upper and lower limbs, with the shoulder joint as the axis, under the coordinated action of muscles such as the deltoid muscle, biceps brachii, and swing forcefully according to specific frequency and amplitude under the synergistic effect of muscles such as the deltoid muscle and biceps brachii.

This swing forms a perfect mechanical coordination with leg movements, providing additional power for the acceleration process through the principle of conservation of angular momentum.

This stage is really different from before.

Forget it once.

This time I overwhelmed Lao Bao again.

Powell understood that it was not a coincidence, but this Jamaican compatriot who had been silent for two years had risen again.

Carter stabilized, and his body posture gradually transitioned from a low-position starting state to an accelerated running state. This transition involved dynamic adjustment of the body's center of mass and fine changes in joint angles. According to the complex mechanisms of motion anatomy and biomechanics, each movement is within the optimal mechanical efficiency range.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! Take another step.

The entire running process has entered a more critical stage of acceleration and deepening.

At this time, according to the positive correlation theory of stride and speed, Carter further increased his stride, and at the same time, based on the synergistic relationship between stride and speed, he continued to speed up stride.

The legs are more powerful under the further stimulation of muscle strength, which involves the recruitment order and strength changes of muscle fiber types.

Under the regulation of the neuroendocrine system, fast muscle fibers contract at higher frequency and intensity, producing stronger explosive power.

Each step is like stepping on a spring with a high elastic coefficient. This metaphor originates from the elastic energy storage and release mechanism of the muscle-tendon complex, just like the compression and rebound of the spring, full of amazing explosive power.

The body leans forward slightly, and the adjustment of this posture is based on the application of aerodynamics in sprinting. By reducing the contact area between the body and the air and changing the direction of air flow, it effectively reduces air resistance.

Strong?

Very strong.

Is it awesome?

Very awesome.

Even Carter saw it himself, he felt that this shot was unparalleled.

Excellent condition.

Maybe I really have the opportunity to challenge the oriental red figure ahead who has been leading the way countless times.

So fast?

This is Powell's head coach, Francis's thought.

He didn't seem to have thought of it.

Carter will suddenly emerge this year.

And this posture.

No matter how you look at it, it feels familiar.

It's not the kind that Carter brought him, it seems familiar.

It is a kind of familiarity brought to him by others.

Who is it?

yes……

A flash of inspiration in Francis' mind.

A clear figure suddenly appeared.

This figure.

He was on the court.

Learning makes people progress.

There is nothing wrong with this.

Athletes in the new era are increasingly unable to work behind closed doors.

This is the consensus of the entire sports community decades later.

The transformation shown by Carter's shot should have shocked everyone at the scene.

but.

This shot has no effect.

Because everyone was too late to be shocked by Carter's performance.

There was someone from Carter's right.

Rapid out.

The body's balance system accurately adjusts the muscle contraction force through multiple information feedback from the inner ear vestibular, visual and proprioception to ensure good balance during high-speed movement.

Bang.

Fast muscle fibers rush.

The explosive power limit is fully opened.

Bang.

Three steps in gold.

The speed increases exponentially, and then gradually enters the best running state based on the speed-endurance curve and energy metabolism balance principle, and reserves energy for subsequent continuous high-speed running.

Just when Carter was about to take the fourth step.

Su Shen has completed the entire startup step.

Start entering the acceleration step.

Step 4 is the key.

This step requires precise control of the muscle contraction force and speed to avoid excessive energy loss and movement deformation.

Unlike the previous steps, Su Shen is not simply pursuing the wanton explosion of power, but rather achieving a perfect balance of power, speed and stability based on motion control theory and energy optimization strategies.

Bang.

Su Shen cleverly added the regulation of intra-abdominal pressure here, which involves the coordinated contraction of muscles such as rectus abdominal muscle, external oblique muscle, internal oblique muscle and other muscles.

By increasing intraabdominal pressure, and according to the principles of hydrostatics, the spine is provided with additional support and stabilize the body posture, just like strengthening the chassis for high-speed racing cars, ensuring the integrity and stability of the body during high-speed running, and preparing for the subsequent sprint stage.

This is the high-end product used in sprinting.

On the basis of frontal mechanics, hydrostatic principles are added.

In order to better transfer to frontal mechanics as buffering.

This wave comes.

Even Ralph Mann looked straight.

Fuck.

How long has it been?

Are you further adjusting and improving the front side mechanics more suitable for yourself???

Since Liu Xiang retired, Ralph Mann will not bring anyone else in training. All his energy is focused on his championship model and front mechanics.

So he didn't know.

This winter training.

Su Shen brought such a surprise again.

Su Shen's body is like a high-speed precision machinery. Based on the stable acceleration of the first three steps, the key to the fourth and fifth steps is to maintain efficient energy conversion.

Using hydrostatics, from the perspective of muscle work, the efficiency of muscle contraction has reached a new peak at this time. The degree of synchronization of the motor units of leg muscles is further improved, especially the coordinated contraction of the calf triceps and the tibial anterior muscle, making the movements of pushing and swinging the legs smoother.

This synergy is based on the complex regulatory mechanism of neuromuscles, just like the various instruments in a symphony.

Step 6.

At this time, it has been suppressed.

But Su Shen hasn't stopped yet.

At this step, the way Su Shen's feet hit the ground also undergoes subtle changes.

According to the grounding buffering theory in biomechanics, his foot quickly transitioned from the outside to the grounding of the whole foot. Through the elastic deformation of the arch, it buffered the ground reaction force like a top shock absorber system and converted it into forward propulsion force.

That's right.

It is another auxiliary theory of mechanics.

If the frontal mechanics proposed at the beginning were just a trunk and had no branches or leaves. Then now Su Shen began to extend various branches based on this trunk.

Let its trunk truly become a towering tree.

At the same time, the swing amplitude and frequency of the upper limbs are fine-tuned according to the principle of motion balance to better cooperate with the movement of the lower limbs and maintain the dynamic balance of the body at high speed.

Although the speed increase of this step seems small, it is a key step towards the extreme speed. Every slight change... is like dancing on the blade, precise and fatal.

This guy.

Even Randy, who was mentally prepared.

They were all mobilized by Su Shen's performance.

Insect the cranial top.

Step 7.

From the perspective of the physiological mechanism of the muscles, his body activated a more complex muscle recruitment mode. The deep muscle fibers hidden deep inside the muscle tissue were like awakened legions, and were in large quantities of battle.

These muscle fibers are activated in a specific order and strength based on the exquisite regulation of the neuromuscular system. They work together with the surface muscle fibers, injecting new power sources into Sushen's acceleration.

In this process, small hip muscles such as the gluteus medius and gluteus minimus become key elements for stabilizing the body. They are like accurate gyroscopes, maintaining the balance of the pelvic with high stability.

The stability of the pelvis is crucial for the transmission of strength from the core to the limbs. These small muscle groups form a highly coordinated dynamic network with the quadriceps of the thigh, biceps femoris, tibial anterior muscles of the calf, triceps, and triceps of the calf.

You said Su Shen.

How can you not be happy?

Just when Carter was still thinking that he had the opportunity to challenge Su Shen to start this game.

Su Shen uses seven simple steps here.

Carter's ambitions were settled.

The energy he burst out in this shot.

It's scary.

You need to know.

This gun has no limit to the gun.

Su Shen's starting reaction was only 0.140s.

Although it's not bad.

But compared to his extreme activation, the gap is still a bit big.

But the more this is.

He is now.

The more terrifying it is.

bang, bang, bang, bang, bang, bang, bang.

Everyone was pulled away in seven steps.

include.

This shot ran away with the extremely powerful Nesta Carter.

What does he want to do?

Could it be that he wants...

Did you solve the battle from the beginning???

Thinking of this.

Carter's coach.

Almost a breath of air conditioning.
Chapter completed!
