Come out thirty meters.

When everyone started looking up.

There has been a clear first group.

Please remember that the first group is now for quite a long time this year.

They are all this number one group.

I won't change it any more.

It is Sushen and Bolt.

These two people started from this game.

As long as there are two of them participating in the competition.

I will definitely die of the rhythm of this first group.

No one else can join.

Seeing Bolt's peak period, he was super amazing. Although he was very happy, he was a little annoyed after a long time. He was like this every time, and he was a little tired of winning.

Everyone can't help but imagine that if one person could go hand in hand with Bolt, two people would have a higher level of confrontation.

Will that feast your eyes even more?

Now.

Your chance is here.

Su Shen also has this opportunity.

Bolt.

There is also.

No longer lonely.

Feel.

It must be good!

Now everyone is behind.

There are only two people in front.

Red lightning and black lightning!

30 meters gradually raised your head!

Su Shen's body's forward angle begins to be larger, about 10-12 degrees. This forward angle helps him use the component force of the body's gravity to increase the horizontal forward propulsion.

His head remains natural and upright, his eyes look straight ahead, and his neck muscles are moderate to ensure the stability of his head and avoid affecting the body's balance and force transmission due to head shaking.

Bolt's body posture is relatively stretched, with a smaller forward angle, about 5-7 degrees.

His height allows him to obtain greater horizontal propulsion at a relatively small forward angle during running.

His head is stable, his neck is relaxed and naturally extends, allowing the body's power transmission to proceed smoothly along the spine.

Bang bang bang bang bang bang bang.

Bang bang bang bang bang bang bang.

Both of them were critically hitting the ground.

The sound of nailing shoes is like hail.

Smashed on the runway.

30 meters!

Su Shen's arm swing was moderate, and the angle between the upper arm and forearm continued to change during running. The angle gradually decreased during the forward swing, and the angle gradually increased during the back swing.

Bolt's arm swing movement is large and powerful. His arm swings starts to exert force from his shoulders, and his arm drives his forearm to swing greatly like a pendulum.

35 meters!

When Su Shen swings his arms, the shoulders are the main force point, which drives the upper arm to swing back and forth, and the upper arm to drive the forearm, and the forearm will naturally sag and the hands will remain half-clenched.

When Bolt swings forward, his arms can be swung to a higher position on his chest, close to his chin or even higher, and when swings back, his arms can be fully extended to the back of his hips.

When Su Shen swings forward to his chest, the height of his hand is approximately near his chin. When swings back to his hips, his arms are straightened but not extended too much, so as to coordinate the movements of his legs to provide additional power support for the body and maintain body balance.

Bolt's large arm swing movement matches his large stride, which can effectively provide balance and additional propulsion to the body, while his body presses forward more.

This is the inertia ahead.

With the inertia of running on the way back, it is getting bigger and faster.

Bang bang bang bang bang bang bang.

Bang bang bang bang bang bang bang.

40 meters!

Su Shen began to adjust his force, and his legs pressed on the ground emphasized explosive rapid thrust, which was to make it more suitable for running on the way.

The same techniques of accelerating running and running on the way require different changes.

This is the science now!

Bolt's legs exerted force, his thrust seemed more powerful and stretched than before.

His physical advantages are especially height advantages.

It began to become more and more prominent under Mills' training.

The cheers were getting louder and louder, but they sounded smaller and smaller.

This is because athletes are becoming more and more focused on their own affairs.

Gradually enter the state of flow.

This will happen.

The people behind them were completely unable to keep up with them.

Even Carter doesn't work now.

Open up to 6.40 and run to 6.30. This is already very strong before, and has been a top-notch existence in history.

Can it be left until now?

Put it in front of these two people.

I can't catch up at all.

Only stay in the third position.

Watching Bolt overtake himself.

Engage lightning confrontation with Su Shen.

right.

It's lightning confrontation.

Yang Jian shouted out here—

Su Shen and Bolt seemed to have turned into two lightnings.

Start to fight hand-to-hand combat beyond everyone else.

It’s not that the rest of the people are not fierce.

It's just at this stage.

There is no one that can be approached.

Bang bang bang bang bang bang bang.

Bang bang bang bang bang bang bang.

When Su Shen hit the ground, his feet pressed down actively, and the angle between his calf and thighs quickly decreased, forming a good buffer. Then, through the coordinated extension of the ankle, knee and hip joints, efficiently converting the reaction force on the ground into forward performance!

When Bolt hit the ground, because the soles of his feet are relatively large in contact with the ground, they can naturally disperse the impact force and obtain greater reaction force.

So Mills told him that after landing, his legs should be better arranged through the sequential stretch of the ankle, knee and hip joints, transmitting powerful strength to the body and pushing the body forward.

It looks very basic.

But through retraining, Bolt's previous voluntary approach now seems more scientific and orderly!

45 meters!

Su Shen is about to enter the rapid explosion point!

At this stage, his leg muscles, especially the biceps femoris on the back of the thigh, gluteus maximus, and gastrocnemius muscles in the calf, contract rapidly!

In terms of body posture, the forward angle of the body is slightly reduced to 8 - 10 degrees, because as the speed increases, the body posture needs to be gradually adjusted to better adapt to the balance requirements of high-speed running.

At the same time, the upper body remains relatively stable.
