The Su God of the Reopening of the Sports Arena

Chapter 2182: It has to explode, the name of Little Mexico City is well-deserved

The first set of results are out.

The second group will continue immediately.

Seeing that Xu Zhouzheng and Wu Zhiqiang have both achieved good results, what else can we say? We must do it.

I can't lose either.

Standing on the runway.

There are obviously eight people.

But it feels like there are only three or four.

Xie Zhengye has surpassed ten this year and has become the most central character.

Although he specializes in 200 meters, he has reached this point and has a place in 100 meters.

It’s just that 100 meters is too long in China now.

This resulted in him not having much room to maneuver.

Those who broke ten times didn’t even have the chance to run a single event.

Look, is this still a short-distance race for flower growers?

Just ten years.

It's been a huge change.

of course.

Seeing the people standing next to Xie Zhengye, Wen Yongyi, and Liang Jiahong, it was still...

Familiar recipe and familiar taste in memory.

Never mind the technology.

They look at it from the perspective of body size.

They are all dimensionality reduction attacks.

Lost a lot of weight.

"The competition is about to begin. This group is a little less competitive, with only Xie Zhengye breaking 10."

These words.

Now Yang Jian said it without saying anything.

It just broke the ten level.

It is already difficult to arouse everyone's attention and enthusiasm.

All I can say is yes.

Ok.

not bad.

Worthy of attention.

After getting into position, Xie Zhengye bent his elbow 30 degrees.

This also allows your anterior deltoid and pectoralis major to be in the best activated state, providing 15%-20% additional kinetic energy for arm swing.

This utilizes the principle of muscle spindle stretch reflex.

What is it that you don’t understand?

Then please go to the traditional department table.

When a child goes.

Simply put, in the starting phase of a 100-meter sprint, when the athlete makes the starting movement, the muscles will be stretched rapidly.

For example, now, when Xie Zhengye pushes off the ground, his quadriceps and other knee flexor muscles are stretched.

At this time, the sensory device in the muscle spindle will be stimulated, generating nerve impulses.

These nerve impulses are transmitted along the afferent nerve fibers to the spinal cord, where they form synaptic connections with motor neurons, thereby exciting alpha motor neurons. The nerve impulses sent by alpha motor neurons are transmitted along the efferent nerve fibers to the corresponding skeletal muscles, causing the stretched muscles to contract.

This generates actions such as pushing off the ground and swinging the arms, allowing the user to gain forward momentum.

Xie Zhengye is already well aware of the role of muscle spindle stretch reflex in the starting phase of sprinting.

He came to this world at the age of thirteen and a half.

I have studied for so many years.

You think you learned it in vain?

First, use the stretch reflex to make the muscles contract quickly after being stretched, thereby generating greater force in a short period of time, helping you quickly get rid of the static state and achieve acceleration at the start.

That is to generate explosive power quickly.

The second is the muscle spindle stretch reflex principle in the starting phase, which allows the length and tension of the muscles to change continuously during the starting process. The muscle spindle stretch reflex can be used to monitor and adjust the state of the muscles in real time.

This allows your muscles to generate enough strength while avoiding injuries caused by excessive stretching, and ensures the coordination and stability of the starting movement.

Simply put, it means maintaining a balance between muscle length and tension.

At last.

Xie Zhengye wanted to take advantage of this.

Improve your neuromuscular recruitment efficiency.

That is to say, repeated starting training will strengthen the pathway of muscle spindle stretch reflex, making the conduction of nerve impulses faster and more efficient, thereby improving the central nervous system's ability to recruit muscles.

Get more muscle fibers involved in the starting action.

Further enhance the power and speed of the start.

Xie Zhengye is also in a period of rapid growth this year, so there will not be any waste.

Always learning to modify and move forward.

Of course, Wen Yongyi is not someone who can be frightened easily.

He is one of the only two people in Asia, besides Suarez, who has won a medal in the World Indoor Championships.

Even Xie Zhengye now has the added benefit of a bent-arm start.

Wen Yongyi is not afraid either.

Because Xie Zhengye would not start the race without bent arms.

That's simply not possible in terms of startup acceleration.

Take any advantage.

Just kidding, Wen Yongyi has much more experience in starting acceleration than Xie Zhengye.

Even if he wasn't starting with his arms bent, he was still in position.

Use the change of center of gravity to move the projection point of shoulder joint forward 5-8cm.

The forward lean angle of the torso is optimized from the traditional 45° to 38°.

This time out.

The ground push angle can be reduced by 12%.

This allows the central nervous system to more quickly and accurately regulate the activation order and number of different types of motor units according to starting requirements, allowing more muscle fibers to contract synchronously and improving the explosive power of the start.

joke.

Wen Yongyi was not someone who could be frightened.

The bent-arm start is amazing.

But it doesn’t mean that.

You will be invincible.

The swiftest sword.

It also depends on who holds it.

Naturally, Wen Yongyi had no idea about people like Su Shen, and it wouldn't be shameful to just admit defeat, but as a young boy, Wen Yongyi didn't intend to give in without resistance.

Xie Zhengye naturally also felt Wen Yongyi's thoughts.

He scanned it.

He actually said to Wen Yongyi beside him——

Brother Yi.

You have to be careful. I am not yet proficient in the bent-arm start and I don’t know how to control the strength. Please go easy on me.

Wen Yongyi just smiled and said -

You don't need to worry about this problem.

Even if you give it your all, I won’t be afraid of you even if I start accelerating.

Liang Jiahong used the leverage effect of the elbow joint to convert the force of his lower limbs pushing off the ground into a trunk rotation torque, attempting to increase the length of his first four steps after the start by 7%.

Liang Jiahong's move is based on the principle of elbow joint leverage.

Add weight to your start.

In human motion, the elbow joint can be regarded as a typical lever system. It is composed of the humerus, ulna and radius to form a lever structure, the contraction of the biceps, triceps and other muscles provides power, and the friction at the joint and the force between the bones form resistance.

According to the principle of lever, the product of the lever arm and the force is the torque. In the elbow joint lever system, the distance from the point of application of the muscle tension to the center of the elbow joint is the lever arm, and the tension generated by muscle contraction is the force.

To put it simply, we should use the point of reasonably adjusting the muscle contraction method and angle to try to change the starting force arm and torque size to achieve efficient force transmission and motion control.

Look, what is professionalism?

This is called professionalism.

I’m afraid that athletes from the traditional department don’t even know how their muscles are distributed.

On Ersha Island, there are three athletes, each with three sets of their own starting modes.

Look at the gap.

Isn't that obvious?

The Su God system is called dimensionality reduction attack.

"preparation."

All three are ready.

Everyone wants to come out on top.

boom------

Gunfire rang out.

Game start.

Liang Jiahong reacted the fastest.

At the moment of starting a sprint, he pushes the ground with his lower limbs, generating powerful pushing force.

This pushing force is transmitted upward through the body's skeletal and muscle structure.

At this time, Liang Jiahong's upper arm swinging action is not performed in isolation, but is closely coordinated with the lower limb pushing action.

While the force of the lower limbs pushing the body forward and upward, it also triggers the body's rotation tendency around the longitudinal axis.

This rotational tendency needs to be utilized and controlled in the proper way so that it can be converted into power to help accelerate from the start.

Obviously, this is what Liang Jiahong is doing now.

The force of the lower limbs pushes the body forward.

Rotation of the body around the longitudinal axis!

Wen Yongyi followed closely behind.

He also has his own unique skills.

At the moment of starting, use the change of body center of gravity and the projection point of shoulder joint to move forward.

During the start of a sprint, the position and changes of Wen Yongyi's body center of gravity directly affect his subsequent starting force effect and starting acceleration ability.

He knew that proper center of gravity control would enable him to generate greater forward driving force at the moment of starting and reduce energy loss.

At the same time, the change of center of gravity not only involves adjustment in the vertical direction.

What is more important is the precise control in the horizontal direction.

For optimal starting position and power transfer.

Wen Yongyi has been around for so many years.

It’s not given for free!

The only two Asian medalists in the 60m Indoor World Championships.

Of course there are a few brushes!

Although Xie Zhengye had the slowest reaction, his burst of power depended on bending his arms.

On the contrary, it may be even more fierce.

Xie Zhengye started with bent arms. When the upper arm-forearm angle was 112°, the moment of inertia of his upper limbs around the shoulder joint was significantly reduced.

The bent-arm configuration reduces the forearm center of mass by 25% closer to the shoulder joint and reduces the total moment of inertia by 18.7%.

Under the same shoulder joint torque, the angular acceleration increased by 23%, shortening the upper limb swing period to 0.28 seconds.

The reduction in rotational inertia directly affects the rotational characteristics of the upper limbs during the start.

According to the angular acceleration formula, the increase in angular acceleration means that the upper limbs can obtain a greater angular velocity change per unit time, that is, the upper limbs swing faster.

During the starting phase, rapid upper limb swing plays an important role in maintaining body balance, coordinating lower limb force, and pushing the body's center of gravity forward.

Here, Xie Zhengye wants to reduce the moment of inertia when starting, because this will have a direct impact on the starting dynamics.

At the same time, compared to when the winter training just ended, he adjusted the changes in the upper limb swing cycle.

The upper limb swing cycle is one of the important indicators to measure the efficiency of the starting technique. In the bent-arm starting configuration, due to the increase in angular acceleration, the upper limb swing speed is accelerated, resulting in a shortened upper limb swing cycle.

This shortening of the swing cycle allows athletes to swing their upper limbs more frequently during the starting phase, increasing the driving force and balance regulation of the upper limb swing on the body.

Especially for improving the efficiency of moving the center of gravity forward during the starting phase.

Even more obvious.

In the starting phase of the 100-meter race, the rapid forward movement of the body's center of gravity is the key to obtaining a good starting speed.

The bent-arm start can effectively improve the efficiency of moving the center of gravity forward by shortening the upper limb swing cycle.

The rapidly swinging upper limbs act as a dynamic balance device, pushing the body forward while maintaining a stable body posture.

Xie Zhengye immediately rushed out, pushed off the ground, and started.

When starting to run, the ground reaction force is obtained by pushing off the ground with the lower limbs.

After all, the rapid swing of the upper limbs when starting with bent arms can adjust the body posture and make the direction of the lower limbs pushing off the ground more reasonable, thereby increasing the horizontal component of the ground reaction force.

It is impossible not to take advantage of it.

Within ten meters, each of them has its own merits.

Start accelerating.

When Xie Zhengye bends his arms and swings them quickly, his body naturally leans forward.

This is to push the lower limbs closer to the horizontal angle.

It is more convenient to accelerate advancement.

Wen Yongyi also refused to give in.

It should be known that the shoulder joint projection point is an important reference indicator for the body's center of gravity in the horizontal direction, so its forward movement can effectively change the distribution of the body's center of gravity.

Through specific technical movements, the projection point of the shoulder joint can be moved forward 5-8cm, which can bring the body's center of gravity closer to the starting line and increase the body's forward potential energy.

This adjustment of moving the center of gravity forward enables Wen Yongyi to better utilize the ground reaction force when pushing off the ground at the start, converting more force into forward acceleration, thereby increasing the initial starting speed.

He has real skills.

I have been specializing in 60 meters for many years.

But it's not as simple as others think.

In order to realize the technique of moving the projection point of the shoulder joint forward, the movement must also be in place.

Specifically, athletes should lean their upper body forward moderately, stretching their shoulders forward while keeping their back muscles tense to stabilize their body posture.

During this process, you need to pay attention to the coordination of the head, neck and shoulders to avoid affecting the control of the center of gravity and the effect of force due to improper posture.

In addition, the support and pushing off of the lower limbs also need to be coordinated with the adjustment of the center of gravity of the upper limbs to ensure that the entire body can generate efficient forward driving force at the moment of starting.

After doing all this, Wen Yongyi started up extremely quickly.

Bang bang bang bang bang bang.

Enter the acceleration run.

Immediately optimize the forward lean angle of the torso.

In the traditional 45-meter sprint starting technique, the forward trunk tilt angle is usually set at °.

However, this perspective has certain limitations in practical applications.

The Su Shen system had already been modified.

For example, although an excessively large forward trunk tilt angle can increase the body's tendency to move forward, it will also cause the body's center of gravity to be too high, making the vertical component of the ground-pushing force too large and the horizontal component relatively insufficient.

This will not only waste energy, but also affect the acceleration effect at the start.

Then Wen Yongyi optimized it to 38° to suit his own physiological characteristics.

This allows you to better balance the horizontal and vertical components of your pushing force while maintaining your body's forward momentum.

A smaller forward trunk tilt angle brings the body's center of gravity closer to the ground, increasing the horizontal component of the ground-pushing force and thus increasing the horizontal acceleration at the start.

Wen Yongyi is not tall.

This is just the right thing to do in the acceleration zone!

Not to mention, the optimized forward torso angle can also reduce the shaking of the body during the start and improve the stability of the body posture.

It will help Wen Yongyi to control the starting rhythm and direction of force more effectively.

The adjustment of the forward inclination of the trunk is not an isolated technical link. It is closely related to the control of the body's center of gravity, the optimization of the ground push angle, and the coordinated actions of the upper and lower limbs. The appropriate forward inclination of the trunk can provide a better basic condition for the optimization of other technical links.

These ones.

Wen Yongyi possesses all these qualities.

He wants to tell these young people.

His own World Championship bronze medal.

It’s not for free!

Let’s look at Liang Jiahong.

A little bit worse.

He has no flex-arm start ability.

He therefore does not have the qualifications to start a speed-up duel with Wen Yongyi, the medalist of the World Indoor Championships.

In the acceleration zone, Xie Zhengye and Wen Yongyi were fighting each other.

Bang bang bang bang bang.

Bang bang bang bang bang.

Two people quickly walked over 20 meters

Thirty meters.

Wen Yongyi was amazed at the powerful performance of the bent-arm start.

Xie Zhengye was also shocked that Wen Yongyi could compete with him so well even though he started the race without bending his arms.

Run on the way in.

Xie Zhengye optimizes the coordinated movement of the upper and lower limbs. The upper limbs bend and swing backward quickly.

The pushing action of the lower limbs forms a good coordination.

This coordination is similar to the synergy between the oars and the hull when rowing. The reaction force generated by the swinging of the upper limbs can provide stable support and balance for the lower limbs to push off the ground, allowing the lower limbs to exert force more fully.

Simultaneously.

At the same time, the coordinated movement of Xie Zhengye's upper and lower limbs can form a coherent power chain, transmitting the force of the lower limbs pushing off the ground to the upper limbs through the core of the body.

The swing of the upper limbs further pushes the body's center of gravity forward.

This means - improving the efficiency of energy transfer and promoting rapid forward movement of the center of gravity.

Wen Yongyi ran without hesitation as he entered.

He began...

Reduce your push-off angle.

Everyone knows that the ground push angle is one of the key factors affecting starting power.

During the start, the ground push angle determines the direction and magnitude of the ground reaction force. A reasonable ground push angle can maximize the horizontal component of the ground reaction force, thereby providing athletes with greater forward driving force.

On the contrary, too large or too small a ground push angle will result in a reduction in the horizontal component of the ground reaction force, affecting the acceleration effect of the start.

Wen Yongyi's number has decreased.

The amplitude even reached 10 degrees.

This optimization of the ground-pushing angle makes the direction of the ground reaction force closer to the horizontal direction, increasing the horizontal component of force.

According to the principles of mechanics, the horizontal component of the ground reaction force is proportional to the cosine value of the ground-pushing angle. Therefore, Wen Yongyi can significantly increase the horizontal component of the ground reaction force by reducing the ground-pushing angle.

Take this as an opportunity.

This will increase your acceleration and speed at the start.

Until the extreme speed zone, Xie Zhengye actually didn't gain any advantage.

As expected, Wen Yongyi is a strong 60-meter runner.

It's not that easy to take down.

But at this time, the extreme speed zone has arrived.

Inextricable?

nonexistent.

Xie Zhengye has begun to prepare for a rapid outburst.

He wants to eat Wen Yongyi alive.

Here.

Wen Yongyi began to be unable to bear it.

Extreme speed level.

It was never his strong point.

He began to get a little anxious.

During the start, the body needs to maintain a stable forward leaning posture to reduce air resistance and facilitate the forward shift of the center of gravity. The upper limbs that are bent and exploded can serve as a dynamic balance adjustment device, which can correct the body's posture deviation at any time by adjusting the amplitude and speed of the swing.

So does Xie Zhengye.

It's getting thinner and thinner.

No longer so careless.

The connection of various technologies.

It’s already reflected enough.

"The speed is here, between Xie Wen and the other one, who can suppress the opponent?"

Who can?

This is of course...

Xie Zhengye.

After Xie Zhengye entered the extreme speed, he began to show suppression thoroughly and completely.

Wen Yongyi no longer has any advantage at this point.

The bent-arm start still has follow-up support.

For example, when starting with bent arms, the kinetic energy generated by the swing of the upper limbs can be more effectively converted into forward kinetic energy of the body.

Bang bang bang bang bang.

When your rapidly swinging arms reach a certain stage, the energy can be released to the lower limbs and the forward movement of the whole body through the transmission of the core of the body.

Fifty meters, sixty meters.

Xie Zhengye continued to adjust.

This energy conversion process is similar to the compression and release of a spring. The process of bending the arm to start is like the compression of a spring to store energy, and then release the energy through the coordinated movement of the body at the right time.

Push your body's center of gravity forward quickly.

It achieves efficient conversion and output of energy, providing strong power support for moving the center of gravity forward.

you might say.

If we just run like this here, what will we do later?

Not much to do.

His name is Xie Zhengye.

He was originally a master with great speed and endurance in history.

How could I be afraid of not having enough strength later?

Don't forget, he is only 19 years old.

It also happens to be one of the times when the body's functions and recovery abilities are at their peak.

It’s not that Wen Yongyi doesn’t want to follow.

But he really couldn't keep up.

His energy.

After the extreme start.

It was already going downhill quickly.

Compared to the future he has been polishing for so many years.

His late-game ability.

Really indescribable.

But this is the price he is willing to pay.

And he also won several medals at the World Indoor Championships through this choice.

For him, in the extremely competitive field of track and field, such international results are already very good.

If I don't choose the 50 or 60 meters, I may not even have this opportunity.

The distance began to widen.

Wen Yongyi couldn't bear it anymore.

Xie Zhengye took the lead.

The scene cheered.

If we simply compare popularity, it would definitely be the young Xie Zhengye.

More central.

But this time.

Wen Yongyi wanted to keep going like this until the end of the game.

But he really is.

think too much.

Xie Zhengye in front had already broken through his blockade.

Rao is a man of courage and determination.

It's impossible to catch up.

I thought it would be okay to be grouped, and it would not be bad to get in as the second place.

But as I was thinking about it, something unexpected happened.

Because behind him.

There was also a strong sound of wind.

Sweeping and approaching.

This is not someone else.

It is Liang Jiahong who is slightly pulled away in the front.

Liang Jiahong's future may be difficult to surpass these two people.

But also after starting at top speed.

He thinks he...

There is a chance.

after all.

He also wants to last 10 seconds.

And he's already tried it.

It is indeed an impenetrable portal.

It takes a lot of opportunities to hit.

His talent.

It's not so easy to open this wall.

But today there are double buffs.

Liang Jiahong.

I want to try it too.

A mechanism for converting torque using the lever effect of the elbow joint.

The transmission path of regulatory force.

When pushing off the ground, the force from the lower limbs is transmitted to the shoulders through the hips and waist.

During the upper limb swing process, the elbow joint is in a dynamically changing lever state.

Take swinging your arms forward as an example.

Liang Jiahong contracts his biceps, pulling his forearm to rotate around the elbow joint. At this time, the elbow joint acts as a fulcrum of a lever, converting part of the force transmitted from the shoulder into a horizontal component force through the swing of the forearm.

This force component acts on the body, generating a torque that rotates the trunk around the longitudinal axis.

Later, Cheng Wenyongyi was not good enough.

Being surpassed.

Although Xie Zhengye’s price was over ten, it was only 9.99 and not many were opened.

Plus the center of gravity is not over 100 meters.

Liang Jiahong still feels himself.

has hope.

Seventy meters and eighty meters.

Liang Jiahong got closer.

His hard power this year is no joke.

Ninety meters.

Xie Zhengye and he were entangled with each other.

At this time, Xie Zhengye and Liang Jiahong had actually secured the victory.

The first two are fine.

This isn't the finals, so why not...

The two people have a good understanding.

Finally, I let go of the ten meters before the finish line.

They originally wanted to burst out with all their strength in the finals.

It would be enough to get a spot in the semi-finals.

call----

They both crossed the finish line.

Take a look at the results.

Both of them were stunned.

Xie Zhengye ran 10.01 in this shot.

The key is not the results.

Instead.

It was quite easy to run.

He himself felt relieved.

It's not like before when I had to risk my life to do it.

Such a relaxing feeling.

After a brief moment of shock, Xie Zhengye soon became full of anticipation for the final in two hours.

Forget about Xie Zhengye.

After all, there are ten contestants.

Liang Jiahong, who came in second, was amazing.

His score for this shot was 10.03.

This……

Plateau area.

Is it so easy to improve grades?

The results are not uncommon.

It's rare to release water.

This result was achieved after releasing water for ten meters.

Then go all out tonight.

Will it be possible...is there a chance?

Breaking ten is nothing to these masters and giants.

It's just an ordinary result.

Even for giants, it is still a deviation.

But for ordinary athletes like Liang Jiahong.

Most ordinary athletes.

They will regard breaking ten as their lifelong goal.

Because for them.

This threshold.

It may take several years or even a lifetime.

The golden life of a track and field athlete is very short.

There is not much time to truly achieve good results.

The length of your career does not determine how long you have to make an impact.

That's all theoretical stuff.

There are actually only a few years in which you can really achieve good results.

I haven't been able to do this in the past few years when I was at the peak of my performance.

That means there is no chance.

Liang Jiahong.

I think it’s not 08 anymore.

I am not a child anymore.

He also wants to be in his career.

Write a stroke that breaks ten.

Even Wen Yongyi, who is third.

This shot's results are...

very nice.

10.07? ? ?

Don't worry about adding a or not.

Never mind whether you are giving it your all or not.

This result.

All are legal.

That's enough.

Wen Yongyi was watching it himself.

Somewhat incredible.

Little Mexico City.

Really.

Well-deserved reputation.

Improve your grades.

Oh, it shouldn’t be said to be achieving results.

It's so easy.

Easier than any race he had run before.
