The Su God of the Reopening of the Sports Arena

Chapter 2159: Hard work...but that's it?

Su Shen entered and ran.

At this time, Bolt also began to show his super talent.

In the past, Su Shen would start to show obvious disadvantages when running halfway.

Lose less.

It's all a win.

But it was 2013.

Su Shen has now completely reached the peak of his body's functions.

Should I...

Let’s do something big.

I saw Su Shen starting to use the three-dimensional ground reaction force control method to adjust the control of the motion trajectory.

To be exact...

You need to get the movement trajectory of the lower limbs right.

Otherwise, you think increasing your stride length is just talk.

Still need to do it specifically.

It's like Su Shen uses the super elastic effect of the Achilles tendon and the force transmission of the plantar fascia to improve his step frequency.

This is just the theory.

So how do we turn this theory into practice?

What are the specific steps?

It also needs to be put into practice in the competition.

It doesn't mean that you can just shout a slogan.

Su Shen started his performance here.

30 m.

When swinging your legs forward and backward, maintain a smooth trajectory to avoid unnecessary movements and wasted energy.

35 m.

When swinging forward, lead with the knee to drive the hip forward, and actively press the thigh down to land on the forefoot.

When swinging back, the calf naturally pulls back to prepare for the next landing.

The arm swing trajectory is also closely related to the regulation of ground reaction force.

Reasonable arm swinging movements can help maintain body balance through body coordination and increase forward momentum to a certain extent.

The amplitude and frequency of arm swing should match the movement of lower limbs so that the three-dimensional ground reaction force can be controlled.

When landing, Su Shen landed on the forefoot, with the landing point as close to the bottom of the body's center of gravity as possible.

Reduce braking effect.

This is actually the key point of regulating the three-dimensional ground reaction force in the horizontal direction!

Subsequently.

When Su Shen extends his supporting leg, the swinging leg quickly swings forward to form a coordinated "push-swing" movement.

Begin to fully utilize the ground reaction force to propel your body forward.

By rationally regulating the three-dimensional ground reaction force, the horizontal propulsion force can be effectively increased, the horizontal braking component can be reduced, and greater acceleration and higher speed can be achieved.

For example, enter the mid-run start.

Su Shen's touchdown point began to get closer to the projection point of his center of gravity.

One of these is to make the direction of the ground reaction force closer to the vertical axis, reduce the horizontal braking component, and increase the speed.

Secondly, the reasonable regulation of the three-dimensional ground reaction force in the vertical direction can also help shorten the support time, increase the step length, and thus improve the speed.

40 m.

During the support phase, Su Shen's hip, knee, and ankle joints need to coordinate to perform "rigid support" to efficiently convert the ground reaction force into forward propulsion.

Hip extension increases stride length and improves ground reaction force effects.

Ankle dorsiflexion increases the reaction force on the sole of the foot, providing forward propulsion.

At the same time, the knee joint also plays an important role in the buffering and extension process, controlling the stiffness and energy transfer of Su Shen's lower limbs.

You can see it if you look carefully.

When Su Shen's feet touch the ground, his muscles control the force of contact and deceleration through eccentric contraction.

During the extension phase, a powerful propulsive force is generated through concentric contraction.

At this time, the torso should lean forward slightly, the hips should be "tucked in", and the neck and spine should remain in a straight line.

This is all to help better transfer and utilize three-dimensional ground reaction forces.

Bolt also entered the mid-run.

He also began to exert his strength.

I thought to myself that I didn't get any advantage by starting and accelerating.

you are vicious.

Could it be.

Run halfway.

Can't I take you down?

Bolt was actually very annoyed that he did not get the corresponding advantage from the previous acceleration.

do not know why.

His competitive spirit was also aroused.

Now, he just wants to take down Su Shen.

Let everyone take a look.

Also for myself to see.

Who is the real champion of this season?

"The mid-course race has begun. Bolt might have to take back the advantage here!"

Mitchell said so.

Quite reasonable.

Just be someone who watches track and field events.

They all think so.

Su Shen is really fierce.

It’s awesome.

Maybe against another player.

No matter in the future or the future, he is already very good now. When facing non-giant level players, there is no so-called shortcoming at all.

Even when facing giant machines, he can now rely on it, having already broken through the back end of 3.40.

Have the ability to resist.

Just a pity.

His current opponents are neither top players.

Not a giant either.

His current opponent is called Usain Bolt.

and so.

While running, people still don't look favorably upon me.

Even though he has run a time under 9.60.

Because of the opponent.

This aspect is too strong.

After the advantage zone ended, everyone thought that Su Shen would start to defend again. Of course, the audience did not blame Su Shen, mainly because of Bolt's running midway...

It's so fucking perverted.

45 super speed.

This is the only such case in human history.

What are you doing?

Respecting objective facts is also a kind of science.

Su Shen...

Of course I know Bolt is awesome.

There are a group of people who run very fast along the way.

Or rather, he knew this better than anyone else in the world.

Two worlds confront each other.

It's not in vain.

Then.

At once……

Let’s touch it.

Usain!

Owner of the Super Run!

we.

Let’s try it from the front.

Bang bang bang bang bang.

Bang bang bang bang bang.

The sounds of footsteps on the field came one after another.

Su Shen ran on the way.

Face Bolt head-on.

During the support phase of a sprint, the muscles of the sprinter undergo both eccentric and concentric contractions.

At the moment the foot touches the ground, the lower limb muscles, quadriceps, gastrocnemius, etc. control the speed and force of touching the ground through eccentric contraction, thereby cushioning the impact of the ground.

Prepare for the subsequent concentric contraction.

During the extension phase, the muscles contract rapidly concentrically, generating a powerful force that propels the body forward.

Regulate the magnitude and direction of ground reaction force.

The core muscles are activated to stabilize the body's central axis.

Provide stable support for lower limb force.

Then the muscles around the hip, knee, ankle and other joints exert force in turn, so that the force is effectively transferred to the ground and appropriate ground reaction force is generated.

The hip extensors then work to swing the thigh backward.

Then the knee extensors and ankle plantar flexors contract synergistically to complete the ground-pushing action and gain forward propulsion.

Bolt is really fierce.

Only when you face him head on can you feel how powerful he is.

Bolt is also making efforts.

Now the rest of the people can't keep up.

Even the giants and quasi-giants.

All they could do was watch.

Nothing can be done.

Unable to join.

I can only watch this pair of lightning.

Start a head-on confrontation.

Mills watched.

unconsciously.

He probably didn't even notice.

His brows.

I don’t know when.

Already a little curled.

this means.

The development of the situation.

Some of it was beyond his expectations.

It's normal that you can't start it.

It was surprising that acceleration did not take advantage.

Bolt should have shown off his prowess during the run.

This shouldn't be a surprise.

Eh.

Don't say it yet.

When you think there are no surprises.

That’s usually when the unexpected happens.

It's all...

Forty meters.

How does it feel.

It still hasn’t gone up much.

How does it feel.

It's still about one meter away.

Mills for a moment.

I wonder if I saw it wrong.

But the reality is.

he.

That's right!

Su Shen ran the first ten meters along the way.

Just hold up to Bolt!

When Yuan Guoqiang and the others saw this... they got excited.

Damn it.

This is Bolt!

This is running midway!

Bolt's advantage zone.

Su Shen has been in a weak position over the years.

Su Shen is here.

I have never been able to withstand it.

Be able to not fall behind.

just now.

What is it now?

he.

Withstood...

Withstood Bolt.

Or running on the way.

Anyone who has done sprinting knows that, even if it's only ten meters.

How exaggerated is this.

because.

That's exactly it.

A picture that shouldn't exist.

Su Shen keeps charging!

The feeling of fighting against Bolt...

every time!

Just leave it to himself.

My blood is boiling too!

Bang bang bang bang bang.

Bang bang bang bang bang.

When the swinging leg swings forward, the thigh is actively lifted, the calf hangs naturally, and the knee joint is relaxed to reduce the resistance to swinging.

Pin him down!

Suppress him as much as possible!

When Su Shen swings his leg to the highest point, he presses down quickly.

In this way, a downward impact force can be generated.

To increase the vertical component of the ground reaction force.

This is to increase the height of the body.

Keep your body upright, leaning slightly forward, your head steady, your shoulders relaxed, and your arms swinging naturally.

The body's forward lean angle should be moderate, generally around 5°-10°. This will allow gravity to produce a component force in the horizontal direction to help the body move forward, while ensuring the body's balance and stability.

The swing of the arms should be coordinated with the leg movements. The hands should not exceed the midline of the body when swinging forward.

Keep your arms straight as you swing back.

This is done by swinging your arms to maintain your body's balance.

At the same time, it drives the body to rotate.

Increase leg extension strength.

Bolt was somewhat surprised and annoyed.

What a joke!

What a joke!

What a joke! ! !

Su actually ran on the way... not letting me catch up???

Bolt has thought about some of the current confrontation scenes with Su Shen.

Don't say it.

But after London.

Whether he admits it or not.

Su Shendu has actually threatened him.

Even if he didn't think about it, his mind would uncontrollably simulate this scene.

But there are so many uncontrolled simulations.

It definitely never happened.

This scene right now.

That's right here.

After I started running on the way.

Unexpectedly, no one was able to surpass it.

It's still in a position where it's neither up nor down.

You can’t really say Bolt is at a disadvantage here.

In fact, since entering the acceleration zone.

At best, they are evenly matched.

If you look carefully, there is still a slight upward momentum.

Just for Bolt himself.

The area after the launch will not gain any advantage.

Especially when running in the middle, you can't get any advantage.

It really made him feel unhappy inside.

accurate.

No.

Bolt was also not ambiguous here, and the amplitude of his hip thrusts began to continue to increase.

His stride was already very long.

It is still improving now.

Than the stride position it should reach.

To be bigger.

Mills actually noticed it too.

Because tall athletes like Bolt have a high stride rate, which is not particularly reasonable in itself.

Or it is unreasonable in itself.

This is also why no coach has been able to bring Bolt out before.

This is the ultimate reason.

It's because of a tall athlete like him.

Everyone is trying to reach two meters.

How could his cadence be so fast?

One by one, the coaches have never considered this issue at all.

Not to mention development.

The same goes for Mills, of course.

Bolt's autobiography makes this point very clear.

Even for Mills, the plan was to have him shoot 400 and 200 at first.

This says about almost all coaches.

No matter how famous or capable he is.

After seeing Bolt's figure.

The first thought that flashed through my mind was...

He can't run 100 meters.

Bolt's own desire to shine in the 100m was what really made him shine, and Mills was more reasonable, which led to his current masterpiece.

Therefore, for an athlete of Bolt's physique, his stride frequency is completely a gift from God.

It seems that no amount of scientific training can increase the stride rate of such a tall athlete.

Even become a cadence player directly.

Mills had no choice.

He felt that might be the only way to do it.

It's God.

In fact, only God could turn such a tall person into a cadence athlete.

So in terms of cadence.

It’s not that Mills has never thought about doing some training and improvement, but he has only tried briefly.

Because he was very clear in his mind that as long as he could push Bolt's unevenness to its physical limit.

That's enough.

The rest is beyond his ability and cognition.

Then just keep your stride frequency and try not to move as much as possible.

To improve his stride.

Bolt's stride length mainly comes from his physiological condition.

But if you say that we have reached the limit, that is far from it.

Otherwise he wouldn’t be a pacer.

Mills just wants to make his stride as close to the proportions as possible for a player of his height.

Or.

Mills had a fantasy in his mind.

That is to create the first in human history.

A tall runner with maximum cadence and stride length.

These words look good when taken alone.

There doesn't seem to be anything special.

But if you combine them together.

So for professional athletes and professional coaching teams, before Bolt...

Definitely see this set of conditions come together.

Will sneer at it.

Because it's simply not possible.

First, tall athletes and cadence flow.

It is impossible to combine them together.

Powell's height of over 1 meters, almost 85 cm, was already the previous limit.

There is not a single one over 1 meters tall.

This is also why Powell's coach, Frasis, previously believed that Powell was the ultimate specimen of human talent.

There was a lot of news of this type back then.

It is generally believed that if you are over 1 meters tall, it is impossible to maintain your cadence.

But Bolt naturally broke this impossibility.

Then he can increase his step frequency and stride length.

The three are combined into one.

At least there is this possibility.

After seeing Bolt show such talent, Mills had a deep thought in his mind:

He wanted to create a super sprinter with a tall stature and good stride length and cadence.

It looks like Bolt has already met that condition.

But in fact it is not enough.

For someone like Mills who strives for perfection.

not enough.

He knew that Bolt's pace might be limited by God.

It is no longer something that can be changed by human power.

But the stride.

But there is still space.

It’s just that I haven’t been able to operate it properly before.

First of all, it was his own self-discipline and lazy character that prevented him from having more room for maneuver.

Fortunately, this year.

Bolt truly became a disciple who could be commanded at will.

This is not easy to achieve.

Because Bolt's emotions were not in place.

The physical condition is not adjusted properly.

This is a very natural thing.

Human beings are inherently emotional animals.

From basic physiological indicators, we can see that when people are angry, excited or in a positive state, they can make their bodies perform better.

This is scientific.

Bolt was always lacking something which caused his body to be inert...

I don't want to push myself to this point.

Mills was also troubled by this matter.

Good thing...

Or it's finally here.

He saw a turning point.

Hayward scene.

Su Shen increased his kicking and stretching strength.

45 m.

The hip, knee and ankle joints should be fully extended to quickly push the body's center of gravity forward and upward so that the horizontal ground reaction force reaches its maximum value, thus preparing for entering the extreme speed zone.

Through the technology of three-dimensional ground reaction force control, joint coordination and buffering are achieved.

During the cushioning phase after the foot strikes the ground, the hip, knee, and ankle joints work together.

The knee joint is bent moderately, with the bending angle of about 130°-140° at the moment of landing to cushion the impact of the reaction force of the ground.

At the same time, the hip joint will also have a certain degree of flexion, about 10°-15°, to help the body's center of gravity transition smoothly.

The ankle joint maintains a certain dorsiflexion angle of 10°-15°, so that the foot can better adapt to the ground, reduce the damage to the joints caused by impact force, and prolong the time of force action.

After that, the elasticity of the calf muscles, Achilles tendon and thigh muscles is used. When landing, these muscles are stretched and elastic potential energy is stored.

Su Shen felt that his Achilles tendon was stretched like a spring. In the extension phase after the buffering phase, the stored elastic potential energy will be converted into kinetic energy.

Ultimately helping yourself generate ground reaction force more efficiently.

Propel your body forward.

The previous ones were completed very well.

Even if it’s the second 2-meter segment you’re running along the way.

He persisted too.

Bolt's pursuit here became a little more intense.

But that's all.

Just a little bigger.

This trend and magnitude.

Bolt was not satisfied.

Su Shen was indeed very satisfied.

He felt that he had touched the key to victory.

in case.

The so-called hard work.

That's the level.

So sorry.

I am about to start reaping the rewards.

It is really.

It’s not as difficult as I imagined.

Of course, it is also possible that I had thought of it before.

It's too difficult.

So actually facing it.

The results were found to be lower than expected.

"We're almost in the extreme speed zone! Su is still leading by a large margin!"

"Has the outcome of this match already been decided?"

Mitchell saw that Bolt was still so far behind here.

He also had similar thoughts as Su Shen.

I've watched a lot of matches between these two.

If Bolt were here, he would still be so far behind.

That's really a bit uncertain.

50 m.

Just when Su Shen was about to burst into speed.

When you want to finish Bolt off in one bite.

This one has been lacking emotional stimulation.

Someone who has no way of turning on the body's inertia switch.

Under the stimulation of anger.

Sudden.

Breaking through a wall.

Mills watched.

The whole person couldn't help but stand up from his seat.

There was no fear on his face.

It’s not the surprise towards Su Shen.

All of them.

The anticipation for the loudest voice in the audience.

with.

excited.

Come on, Usain, show the world.

Your real ability!!!!!!!!!!!!!!!!!!!!!!

Show it!!!!!!!!!!!!!!!!!!!
