This situation.

Bolt sends the hip to drive the forward swing of his legs, so that the initial position of the pressure center when his feet hit the ground is further back.

Then as the center of gravity of the body moves forward, the center of pressure quickly moves forward to the forefoot.

This works in concert with the hip-sending action, and jointly converts the ground reaction force into forward propulsion force, optimizing the acceleration process.

very good.

continue.

Usain.

Continue to show your talents and strength to the world!

Mills looked at her heart and felt excited.

It was like taking off with Bolt.

For example, this one-single-step.

Bolt's hip extension and rotation can generate larger joint moments.

The moment generated by contraction of hip muscles such as gluteus maximus.

This directly contributes to joint torque power.

At the same time, the hip delivery movement transmits the power of other parts of the body to the lower limbs through the movement of the hip joint.

The joint moment power of the knee and ankle joints cooperates with each other.

In the acceleration zone, this synergistic effect allows Bolt's joints to generate force more efficiently and increase the overall joint moment power, thereby providing stronger power for body acceleration and achieving more effective acceleration and progress.

In addition, the rhythm and strength of Bolt's hip delivery will also affect the output timing and size of joint torque power.

Matches the requirements at different stages of the acceleration zone.

To achieve the best acceleration effect.

This is what Mills said - at different stages of the 100-meter running, if the joint torque power can be flexibly adjusted according to the actual situation.

Then you can naturally break through the original limit.

Now Bolt.

What is being done.

That's it.

Even if there is only acceleration.

All are enough for him to be majestic.

It made Mills feel "intoxicated" when he looked at it.

after all.

This is my most proud work.

Every progress.

It's all about your own value.

It's really strong.

It's really good.

Mills's philosophy.

It also fits Bolt's running.

It's just a pity...

Here now.

There is another person.

It's not just Bolt and Carter.

And human is an animal.

What I fear the most.

It's just that people compare themselves.

In comparison.

OK.

It will also become bad.

The top will also become ordinary.

...

“So fast…”

Yuan Guoqiang was a little worried.

Bolt is too fierce.

Unexpectedly, he actually made progress.

Acceleration zone.

It is also improving.

At least technically.

Even better.

This is Bolt.

Worry is right.

unless.

You know so much like Randy.

"rest assured."

"Yuan."

Randy intervened and watched, without any urgency.

Instead, I was expecting it:

"I'm optimistic."

"The whole human being will progress because of him."

What's the meaning?

Yuan Guoqiang hasn't said that.

Next second.

Someone has shown it.

It's right here.
Chapter completed!
