"It's hard to say."

Even the people from Team Su faced such a scene.

Facing Bolt.

I don't dare to make a promise.

Zhou Bing and others also watched with their hands crossed.

Only the rhythm of fingertips hitting the arms.

Only then can I see it.

Each of them was nervous inside.

Bang----------

Electronic gunshot.

"The competition begins!"

The fastest reaction was Zhang Peimeng, but his reaction was useless even if it reached 0.127 seconds.

Mainly because his condition in this shot is no longer as good as the preliminaries.

It is not only physical energy consumption, reserve consumption, but also neural state consumption.

Even Zhang Peimeng reacted well.

The first kick out.

I felt something was wrong.

As a professional athlete.

He knew if he was in good condition after stepping on it.

In the end, it was affected by the full breakthrough in the preliminary round.

Except him.

There are also people who want to press the gun.

This person is Nesta Carter.

Carter is the master of this group of startups.

Every time I fight with Su Shen, I am full of enthusiasm.

Even though he knew he could not escape now.

That would not affect his enjoyment of confronting Su Shen every time.

This time is no exception.

And on the start.

So what if Bolt makes improvements?

Could it be?

Can you still compare yourself?

Carter takes violence!

Reaction time 0.130s!

Ranked second among all!

Here, Carter also began to make his own changes.

The first is the improved "four-point support".

Also called knees - asymmetric support of both hands and body center of mass conversion.

The height of the body's centroid is a key element in motion stability and dynamics.

Carter uses asymmetric support method of knee-two hands to break the traditional symmetric support pattern.

By finely adjusting the force distribution of each support point, the precise control of the body's center of mass is achieved.

According to the principle of statics, when the area of ​​the support surface of an object increases and the center of mass decreases, its stability is significantly improved.

In this preparatory posture, the athlete's physical center of mass decreases by about 5-8cm.

This change allows athletes to obtain greater horizontal driving force at a lower center of gravity at the moment of starting, reducing shaking and energy loss during startup caused by excessive center of gravity.

In other words, a lower center of mass can enable athletes to generate more effective horizontal force during the instant of pushing the ground, pushing their bodies forward quickly.

If Su Shen saw this move after the game, he would watch it.

I definitely think it looks very familiar.

Isn’t this the posture I was before I started with a bent arm?

In his previous life, he won 6.42 in this mode and form and was the first world-class silver medal in the international competition in Asian history.

If Coleman hadn't appeared in the peak game at that time.

The champion of that year should be himself.

However, Su Shen in this life made model adjustments early.

I have never walked this path.

Instead, Carter was constantly observing himself and walked out of him.

The first step is to get out.

Control the torso forward angle to 42°±3°.

From the perspective of human movement chains, changes in torso posture will directly affect the mechanical state of lower limb joint muscles.

When the trunk is at this specific angle, the initial length of the hip extensor, i.e. the gluteus maximus and biceps femoris, is effectively shortened.

According to the length-tense relationship of the muscle, the muscle can produce the maximum contraction force at a certain appropriate initial length.

At this forward angle, the initial length of the hip extensor muscle is adjusted to close to its optimal force length.

This allows muscles to recruit more motor units to participate in their work when contracting, and improve the muscle contraction effectiveness.

This means that during the starting and pedaling stage, these muscles can generate greater strength.

Provides athletes with stronger startup energy.

Plus, stretch reflex sensitivity enhancement training.

At the moment of starting, with the rapid stretching of the muscles, the muscle shuttle can more quickly transmit the signal of length change through the afferent nerve to the spinal cord center. After the spinal cord center is integrated, it quickly passes the instructions to the muscles through the efferent nerves, causing the muscles to contract quickly and strongly.

This enhanced tension reflex allows athletes to respond quickly when starting, burst out powerful forces, and shorten the reaction time of starting.

Increase the starting speed.

Carter is constantly refining here.

Plus, my own talent is quite good.

In this regard, it has achieved a level that even Su Shen did not do in his previous life.

Of course, it was because Su Shen was too late to conduct real scientific and professional training.

I really met Randy.

It was not until 2018 that I gradually developed myself.

He was already twenty-eight or nine out at that time.

Therefore, if you train scientifically earlier.

Even with this set of startup training models.

It won't stop at 6.42s.

Perhaps using this set, the indoor competition was able to hit 6.40 and run to 6.30 that year.

After the age of 25, it is generally believed that they will retire. This is the age when Asian sprinters were preparing to retire from the second line.

Su Shen himself had already issued a retirement report in his previous life.

A breakthrough was made.

It’s just a pity that it delayed the peak functioning of one’s body.

Carter did a good job.

Quite excellent.

No wonder his coaches this year also felt that Carter had returned to the peak and even advanced beyond the previous one.

This chapter is not over, please click on the next page to continue reading! This performance.

It is the ideal model state before Randy let Su Shen train the bent arm to start.

The second is continuous steps.
