Liu Xiang looked at the fourth column in front of him.

The flexion of the lower limbs is followed by the flexion of the lower limbs. The gluteus maximus behind the hip joint, the quadriceps in front of the thighs, and the triceps in the calf behind the calf are lengthened to complete centrifugal contraction.

This is to store elastic properties across time and enhance the nerve reflex, as well as create favorable conditions for improving the contraction effect of muscle groups.

Then when the body moves forward and the center of gravity passes through the support surface, the joints of the lower limbs of the legs will quickly stretch and start to push the ground and start to move the cross.

The swinging leg swings forward with the hip joint as axial axis, and drives the calf to flex and form a folding forward movement.

start up.

Cross.

Liu Xiang's technical links, especially in the past four years, have been scientifically corrected by Ralph Mann.

Especially after studying on Ersha Island, Liu Xiang's understanding of short-span body structure is much better than his previous ignorance.

The minimum requirement for Ersha Island is now-

As a professional athlete, you must clearly know what muscles and muscle groups you should mobilize to start the main work when doing technical movements.

If I don't know this...

Then you should read and recite the book first.

Don't worry about getting on the road.

You can't even figure out the instructions for your body, what else do you want to do?

Learn the instructions first.

The fifth column.

Merritt was still by his side, and the sound pressure caused by the other party's running was on the side of his ear.

At this time, Liu Xiang had already devoted himself to his mind and began to focus more and more on the running movements.

The hip flexor muscle groups, such as iliopsoas muscle, rectus femoris, sartois muscle, etc. are fixed and the posterior femoris muscle groups complete centripetal contraction.

Remember Ralph Mann told himself:

Although large muscle groups such as iliopsoas muscle play a decisive role in the powerful forward swing of hip flexion, flexing the calf at the same time reduces the rotation radius, which is also positive for increasing the swing speed and forming a whip-like swing pass.

You can't just mobilize the big muscles.

The remaining small muscles should be mobilized as much as possible.

Because this person around you...

not simple!

"Oh! Liu also started to exert force! His running along the way, especially in the later range, was extremely strong. I wonder if he could catch up with it?"

The on-site commentator said that Sun Haiping on the sidelines also pinched his thumb into his index finger.

All of them are a little white in the press.

But he didn't seem to notice it.

Inside the eyes, there was only the red figure on the runway.

He knows, too.

What did Liu Xiang pay in four years? He finally got up. This Olympic Games will definitely not be missed.

but……

The better Liu Xiang ran.

Now Sun Haiping is becoming more and more worried.

Why are the better you have to worry more?

This is because.

Liu Xiang, the better he ran, did not show any obvious momentum of overtaking, which is enough to show how outstanding Merritt next to him is also running.

So Liu Xiang came up with this state.

Still unable to complete suppression.

This shows...

Merritt's condition and current strength.

More than I had estimated before.

I'm afraid it's better.

Almost at the same time.

On the other side.

Merritt's coach Andreas Bime looked excited and kept saying in his heart:

Yes.

That's it.

Aris.

Show the world your abilities.

Use the world record holder as a footnote!!!

The coaches on both sides are staring at their athletes, but their thoughts are very different at this time.

On the runway.

Richardson complained in the back that neither of them were normal people.

It's still so slippery when it rains.

It's not just running.

This is a hurdler.

It needs to take off.

The impact of rain and slipperyness will undoubtedly be greater than that of ordinary flat runs.

Anyway, Richardson wouldn't dare to do this.

This is too easy to get hurt.

The Olympics are coming soon.

A problem occurred at this time.

Not worth it.

But this is because he does not compete for championships, and his championship mentality is not so urgent.

And Liu Xiang and Merritt.

The two of them went almost for the Olympic champion.

Both of them have such strong thoughts.

therefore.

That is why there is the current battle between dragons and tigers.

Don't give in to each other.

Because Merritt practiced gymnastics, his straddle movements were coordinated and coordinated by the legs, especially when attacking the railing, which was the knee joint, which was very exquisitely manipulated in his current state. Every time he straddle, his coach Andreas Bime felt as if he was being stepped on the tip of his heart by a little girl wearing high heels.

It's really...excellent, no, even perfect knee joint technology.

He would have such an exaggerated idea, mainly because the rotational force is obtained by the flexor muscles of the thigh, so that the inertia time around the thigh can be reduced, thereby increasing the angular speed of the swinging leg.

Merritt's knee joint technique is really perfect.

Anyway, Andreas Bime couldn't find any problem.

He even felt...

This is the textbook.

It is the most ideal existence.

Merritt this year.

It's really that level.

His technical links and rhythm have indeed reached the best level in history this year.

Before no one surpassed him.

In his previous life, he was the real king of these places.

It is an "idealized" existence.
