The Su God of the Reopening of the Sports Arena

Chapter 2139 I'm sorry for making you pay for it

how.

Is this guy so fast?

Gatlin and Dix were both dumbfounded.

They are all very confident in their ability to start.

Even if it's not the best, it's not...

It will be compressed like this.

This……

Do you feel stressed?

That’s not all.

The goal of the start phase is to reach a high horizontal speed in a short period of time and maintain a steady acceleration.

According to the principles of kinematics, speed is a vector, including magnitude and direction. Unnecessary ups and downs will cause the direction of speed to fluctuate and interfere with the athlete's control of horizontal speed.

In a cadence start, a high cadence requires a steady rhythm to maintain.

The ups and downs of the body will disrupt this rhythm and cause the stride rate to be unstable.

It is as if when the body rises up, the time when the legs touch the ground and the direction of force will change.

This will make it difficult to maintain a stable high cadence.

A stable cadence is crucial to leveraging the advantages of a cadence-type start. Only by maintaining a stable cadence can you continuously provide the body with forward momentum.

Su Shen was here before and taught Xie Zhengye a lesson.

Xie Zhengye's life has been very up and down.

This is for the bent-arm start in the stride flow.

Very unfriendly.

From the post-match video analysis slice of Xie Zhengye, we can see that Xie Zhengye failed to control his horizontal speed when he started running with bent arms.

not too good.

Although, it is normal to have some problems in the beginning.

Even many of the problems are normal.

but.

Still the same sentence.

Who told you to be Xie Zhengye?

You called this name.

Su Shen in this life.

You will definitely not be allowed to rest.

Bang bang bang bang bang.

Try not to change the time your legs land and the direction of force.

After Xie Zhengye took control of this place, not to say that all the problems were solved, but at least it was much better than when he was not paying attention.

After solving this problem, he felt his pace...

More stable.

Sure enough, in the end, it was just as Su Shen said.

Sometimes it is not a targeted solution to your problem.

Instead, we should start with other issues.

Use other problems to drive the solution of your problem.

Don’t you think so?

Very convoluted.

But that's what happened later.

You have to do this with tongue twisters, too.

You also have to understand what it means.

After stabilizing this place, we can——

Improve acceleration efficiency.

From the perspective of dynamics, Newton's second law F = ma, where F is the net external force, m is the mass of the object, and a is the acceleration, shows that -

When the mass remains unchanged, the greater the resultant external force, the greater the acceleration.

Then.

At the start, can you push it out?

Reducing the up and down movement allows the athlete to focus more of their power in the horizontal direction.

Thereby increasing the resultant external force in the horizontal direction?

Just like Xie Zhengye before, when the force is mainly used to overcome the ups and downs, the horizontal force will be relatively reduced, resulting in a decrease in acceleration.

So after changing it.

By reducing unnecessary up and down movement, more energy can be used to propel the body forward.

Increase horizontal acceleration to increase speed more quickly.

This is especially important in short-distance running events, as rapid acceleration at the start can lay a good foundation for subsequent mid-distance running and sprinting.

Xie Zhengye felt as if he had suddenly found a switch. Not only his stability, forward movement, but also his horizontal force had improved...

Even the whole person is accelerating on the curve.

There were completely different feelings.

It's just like.

The entire curve becomes smoother.

It was as if lubricant was injected into my body.

The previous feeling of having some cackling noises on the bends.

This time it was much lighter. He could put more power into it.

Used to move forward.

Is this what Mr. Su is capable of?

I rely on.

With just a few words, he solved a problem that was difficult for him and his team to solve.

One method has led to changes in several ways.

This brain.

It’s no problem to say that he can turn stone into gold.

No wonder they can’t even count their money.

Have such a brain.

What to do that doesn’t make money?

By reducing the ups and downs, Xie Zhengye has made changes to so many technical aspects in disguise.

What do you think.

If this person doesn't become stronger, who will become stronger?

If this doesn't speed up, who will?

Xie Zhengye showed his full ability, and he had already opened up his 10-second -meter body memory.

All of these made his shot even more ferocious.

Gatlin's distribution running style.

It's totally not his place.

So what if the 100 meters is faster?

This is 200 meters.

The approach is completely different.

And the Gatling method.

It's behind the times.

Ashmid watched, his mind also numb.

He was right in front of Xie Zhengye.

This feeling is most clear.

Come on, this has a forward extension.

This is not 100 meters.

What are you doing?

How come you caught up with me like this?

You have to know how to eat it on the curve.

That means, if converted into a straight track event.

He was already ahead.

100m Ashmead is currently at Pb9.93.

The 200 meters was 19.85.

No matter which one, he is no worse than Xie Zhengye.

Especially the 100 meters, which should be his strong point.

If they run the 100-meter race at the same time, Xie Zhengye will most likely not be able to beat him.

But now.

He's on the curve.

But he was chased by this Oriental man.

Chase by the butt.

Such a feeling.

Ashmid is really frustrated.

He was intercepted by Zhou Bing in the 200m preliminaries, and in the 200m final, he was actually chased by a man who was less than years old.

The essential.

This person is also an Oriental.

Damn!

How come Oriental people are so good at running?

I still like the way you used to be easily crushed by us.

nonsense.

Any race likes it.

Ourselves.

Of course I like it too.

and so.

Let us just appreciate the expressions on your faces when you are being suppressed by yourself.

Xie Zhengye drove at full speed, and his whole running was extremely smooth. Even Zhou Bing glanced at this and was a little amazed.

these people.

They are all monsters.

It took me 20 seconds to open it.

It turned out well for him.

It has reached this level.

And you still say that progress is progress?

And you say growth is growth?

Every step forward comes at a huge price.

They all rely on the bent-arm start technique that has been honed for ten years, as well as the plateau venue and good wind.

It took so many conditions combined together to achieve a breakthrough.

Although breaking through that wall is the most difficult the first time.

But that doesn't mean it will get easier later on.

It's still difficult.

The higher you advance, the harder it becomes.

The 200-meter sprint is not just about 20 seconds.

Thank you for your work.

But right under his nose, it seemed like he had come to his senses again.

The whole technology feels definitely better than it did some time ago.

To make further progress.

We train together every day.

Many times, I even focus my attention on Xie Zhengye.

Observe silently.

After all, Zhou Bing was once the number one in Asia in the 200 meters.

My eyesight has been trained over the years.

He noticed it almost immediately...

Xie Zhengye.

Definitely a lot of progress.

This is the feeling of his startup.

has changed.

He is not sure what the changes are.

There was no time for him to think too much.

But for now.

One thing is certain!

This change is definitely in the direction of...

The good side.

Hayward Stadium.

Xie Zhengye took the lead.

The acceleration on the curve was even enough to catch up with Ashmid in the sixth lane.

Ashmid had always felt that he and Xie Zhengye were the same.

Half a catty.

The medal in the 200m.

He also had a chance to fight.

It's just that he didn't perform so well.

Even if he admitted that Xie Zhengye did have some strength.

But that would at best be his equal.

Never thought about it.

He is actually better than me.

And it’s much stronger.

It's ok.

It’s okay to deny it.

The tradition of Ersha Island is——

With the iron fist of facts.

Beat you until you surrender.

Bang bang bang bang bang.

Running halfway into the curve.

At this time, Xie Zhengye began to take a step further and keep his body's center of gravity stable. A stable center of gravity is not only important during the start, but also important for maintaining body balance during acceleration, especially mid-run.

In the cadence-type flexed-arm start, the high cadence results in a shorter support period for the body.

If the body moves up and down too much at this time, it will be difficult to keep the center of gravity in a stable position and it will easily go beyond the support surface, which may seriously lead to falling or losing the starting rhythm.

Yes.

Or is it the problem of the body moving up and down too much?

one question.

I can still eat it now.

Really.

This shows that knowledge also requires cognition to improve and utilize.

Do this well.

Then it is necessary to…reduce up and down movement to keep the body’s center of gravity at a relatively stable height and position.

Used to reduce the possibility of losing balance.

This allows you to move forward more steadily during acceleration and mid-run.

Xie Zhengye's approach here is:

Coordinate the movements of upper and lower limbs.

Why do you want to do this?

Because the ups and downs of the body will also affect the coordinated movement of the upper and lower limbs.

When running, the arm swing of the upper limbs and the pace of the lower limbs are coordinated with each other to maintain the balance of the body and generate forward momentum.

When the body moves up and down unnecessarily, it disrupts this coordination.

For example, last year’s Diamond League.

Xie Zhengye made this mistake.

Forget that when the body rises and falls upward, the swing amplitude and rhythm of the upper limbs may change in order to maintain balance.

This will affect the step frequency and stride length of the lower limbs.

This resulted in poor coordination between the frequency and stride of his lower limbs on several occasions.

Although for ordinary people, it is as good as it can be and is already perfect, but as an athlete, you should just listen to the word perfect.

Believe it.

That's a big fool.

In the field of competitive sports, perfection or imperfection is always determined by the object of comparison and the level you are at.

If your perfection outside of 20 is within 50, it is no longer perfect.

Your perfect score under 20 seconds can be put under 50 seconds.

Imperfections will also occur.

This is the spirit of scientific research that should be possessed.

Su Shen has been practicing and promoting this concept and spirit on Ersha Island, and the results are very significant, which has influenced almost all young people on Ersha Island.

And what Su Shen wants him to do is...reducing the ups and downs can make the coordinated movement of the upper and lower limbs smoother.

If the energy continuation pushed by the bent arms of the upper limbs can be better coordinated with the high step frequency of the lower limbs, it can provide the body with stable balance support and forward propulsion.

Then run on your way.

It will also be faster and more stable.

Of course, there are other things to pay attention to here. If your theory and direction are correct, but you don’t pay attention to the changes in the courier himself, that won’t work.

During training, Su Shen told Xie Zhengye that when the body moves up and down, the joints of the lower limbs, such as the knee joints and ankle joints, will bear greater impact force.

According to the momentum theorem Ft = Δmv, where F is the force, t is the action time, Δm is the mass change, and v is the velocity change. When the body falls, the sudden change in velocity will cause a greater impact force on the joints.

Then.

Reducing the ups and downs reduces the impact on your joints with every step.

This reduces wear and tear on the joints and the possibility of injury.

Joints are also areas that athletes need to protect. Don’t think you can do whatever you want just because you are young.

What Su Shen told him specifically was to maintain the normal movement trajectory of the joints.

This trajectory changes as your body, muscle and physiological conditions change.

Champion model systems are often used for calibration when needed.

Because in normal running, the movement trajectory of the joints is relatively stable and regular, but the ups and downs of the body will change the force direction and movement angle of the joints, causing the movement trajectory of the joints to deviate.

Especially on the curves.

Because it is not a straight road, it has to withstand the double impact of centripetal force and centrifugal force.

You must keep adjusting yourself so as not to get injured.

If Su Shen didn't tell him these things and didn't directly give him the answers, he would never be able to figure them out.

It is impossible to pay attention to so many aspects. This is the advantage of having the version answer directly.

Many times, even if you have the right direction and method, you may not be able to train an athlete, because you have to consider other aspects, especially the injury itself.

As much as possible, on the basis of making these changes, we will enable athletes to follow scientific rules and avoid injuries.

Only here can you understand that Su Shen is doing this for the entire Ersha Island.

What a huge sacrifice.

Bang bang bang bang bang.

Run on the curve!

At this time, only Dix could still keep up, but he had to run halfway through the bend because he had just returned from injury during the season.

I dare not use full horsepower in one breath.

This is why his performance in this game was not actually very good in history.

Especially when he was about to come up and put some pressure on Xie Zhengye, Xie Zhengye was running in the middle of the curve and unexpectedly...

It ran very smoothly.

That's how Bidix remembered him anyway.

A lot smoother.

This is because, under the guidance of Su Shen, he began to enter a more advanced field.

That is, the balance between centrifugal force and centripetal force in a curve.

How do we usually overcome centripetal force and centrifugal force?

Just share it.

Whatever the theory, it's basically the same now.

But Su Shen told him...

When running on a curve, athletes need to rely on centripetal force to overcome centrifugal force.

to maintain track on the runway.

Yes.

Use centripetal force to overcome centrifugal force.

Use centrifugal force to counteract centripetal force.

I rely on.

When these words came out, although Xie Zhengye didn't understand, he also felt it was impressive.

Yang Yaozhu, who had been studying the adjacent subject for many years, was so shocked by these words...he almost couldn't close his mouth.

While they were still thinking about how to encourage each other to face this difficult corner, others had already thought of combining forces, leveraging each other's strengths, and using each other for their own benefit.

Really.

The pattern is different.

Absolutely.

Just listening.

Everyone finds it scary.

I immediately understood where the difference between people lies.

According to the centripetal force formula, the stability of velocity direction is crucial to maintaining the stability of centripetal force.

There are a lot of things, but now Xie Zhengye only has to solve one problem - it's still the ups and downs problem.

No need to distract.

Remember that unnecessary up and down movement of the body will cause the vertical component of the velocity to change direction.

Interfere with the stability of centripetal force.

This ultimately makes it difficult for athletes to accurately control the trajectory of their bodies in the curve.

Increased risk of veer off the runway or deviating from the optimal curve route.

Just this one point, actually...

It goes through the entire curve.

Su Shen’s advice.

It really makes people of Xie Zhengye's age feel...

not simple.

This brain.

Much better than myself.

Not in the same dimension.

You can even tell by looking at Yang Yaozhu's expression.

He even began to have doubts.

Does Su Shen have an extra brain?

Otherwise, why would it be so scary?

Talk to him professionally.

It's just a blow to yourself.

After Xie Zhengye paid attention to these aspects, he had already pulled away from Dix who was afraid to give his full strength.

I thought.

Dix also puts a lot of pressure on himself.

did not expect.

It's gone so quickly.

Xie Zhengye felt helpless.

There is no imaginary enemy.

That can only be...

Do these aspects as well as possible.

Let himself hone those areas that Su Shen wants him to improve in actual combat.

Actually, talking about Dix versus Xie Zhengye is going too far.

At least this shot.

Far away.

Because.

He has no way to fight against Xie Zhengye now.

Now to consider.

Can I keep the second place?

because.

There was another person who was almost always keeping pace with him.

This person is Zhou Bing.

Zhou Bing also broke the 20-second mark.

If you are a healthy Dicks online.

Then Zhou Bing had no choice but to admit defeat.

There is indeed a big gap in hard power.

But here's the thing.

Are you in your prime now?

Neither are you.

Since you are not.

Why can't I surpass you?

After Zhou Bing started accelerating and gained the advantage, he was caught up by Dicks and almost overtaken.

But this time point is very short.

Because it’s time to go down the bend.

Once past the top of the arc.

Zhou Bing began to exert his strength and gradually re-established his advantage.

But Dix is at least one of the fastest cornering prospects in history at this time.

The foundation is still there.

Still able to tangle with Zhou Bing.

but.

That is to say, it is a tangle.

One more time.

Will not work.

Curve into the straight.

Needless to say, Xie Zhengye was the first one to run in. The second one...

But not Deeks.

instead.

Zhou Bing.

The two yellow-skinned athletes actually rushed out of the curve first, one after the other.

This makes the so-called old fans of the Athletics at Hayward Stadium.

Each of their defenses were broken seriously.

The 100-meter position was lost.

Are we going to lose the 200-meter position too?

Don't waste our taxpayers' money!!!

Xie Zhengye looked ahead and knew from the sound that there was no one within a one-meter radius of him.

really.

I paid attention to the aspects mentioned by General Su.

I just ran faster.

Or at the same speed.

He ran more easily.

Then.

Enter the main straight road.

There is also more energy left to rush to the finish line.

……

China Sports Channel.

"From the curve to the straight, Xie Zhengye and Zhou Bing rushed out of the curve first, one after the other. They are now in the lead!"

“No American runner could keep up with them!”

"Look at the long straight road. This is Xie Zhengye's advantage. He is very fast and has no intention of stopping."

"Keep speeding up. Zhou Bing is not bad, but Xie Zhengye is still better!"

"Xie Zhengye keeps accelerating, accelerating. There is no one around him. He has secured the championship. Let's see..."

"What is the score of his lock?"

Xie Zhengye did not hesitate.

He headed straight for the finish line.

call----------

"Press the line!"

"19.90!!!"

"No, it's revised to 19.88 again!"

"and."

Yang Jian took a quick glance and said, "It's still a headwind of nearly one meter!"

"The hard power of this shot is probably not much worse than London's result!"

"Xie Zhengye ran well, but the weather was not good."

Xie Zhengye was watching and felt a little dissatisfied.

He originally thought that he had run quite well in this race. Although he did not have the threat and excitement of his opponent, it should not be possible to achieve such a result.

He himself has made improvements in these areas.

Isn't that a bit of an improvement?

But you can look at the wind speed.

outrageous.

Although the wind speed is 0.9 seconds.

But he was a 0.9 second headwind.

Headwind and tailwind are different.

The negative blessing brought by headwinds.

It is likely to be better than the benefit brought by a tailwind at the same wind speed.

To influence more.

This is the inference.

It seems to be okay.

Xie Zhengye also smiled a little.

Even with a strong headwind, he was able to reach 19 seconds.

Look at it this way.

That seems to make sense.

In addition to Xie Zhengye, Zhou Bing also ran a good result of 20 seconds in this race.

Scientific wind control technology.

He is the third person in the entire Ersha Island who has learned this.

It would be outrageous not to use it.

Then it would be a waste of time.

Zhou Bing also looked at the wind speed before nodding.

Otherwise if it is normal wind.

He would not be satisfied with this result.

Took the top two places.

And this time it’s not 100 meters.

It is 200 meters.

Still in Eugene, the hometown of track and field.

How to say.

I'm so tired of winning.

Of course, this is not a good experience for the audience.

Meaning USA Track and Field.

Another advantageous project is about to lose its advantageous position.

Forget it if we can’t beat Jamaica.

Even an Oriental can't outrun him.

You guys are such a waste of money.

Ah.

How can you not deserve to lose to us?

Xie Zhengye was just about to be interviewed when he heard such voices coming from the stands. He suddenly smiled, rolled his eyes, and moved the microphone of the reporter closer.

Young people are full of energy.

I don't want to spoil you too much.

Besides, he was the winner just now.

Is the champion.

Xie Zhengye coughed lightly and said:

"The Hayward crowd."

"You'll pay for your sins."

"I'm very sorry."

ha? ? ?

Not to mention America, many people in the Flower Growers team were stunned when they heard this.

young people.

I really dare to say it.

"but……"

Zhao Haohuan added:

"Compared to you back then."

“It’s still a long way off.”

what?

I?

Su Shen said: "Am I so exaggerated?"

"Are you exaggerating that much?"

Zhao Haohuan shook his head, as if he saw memories of those years in Xie Zhengye, and said:

"You were in a much more frightening environment than him."

"Sometimes when I hear this, my heart almost stops beating."

"Of course it looks like that now."

"you are right."

Zhao Haohuan smiled as he looked at Xie Zhengye, who was full of energy and vigor.

"We are a track and field athlete from the flower-growing family."

“You don’t have to be inferior to others.”

"No worse than others."

“There is one sentence I still remember.”

"What?" Su Shen asked.

After the reopening, he said too much.

I don’t know what Zhao Haohuan was talking about.

"You have to get used to the fact that we can be better than others."
