The Su God of the Reopening of the Sports Arena

Chapter 2194 High Energy, Start

Bang——————

As the gun sounded, everyone started immediately. No one rushed to start the race.

Xie Zhengye and Zhou Bing wanted to start by bending their arms.

Take a chance to get the advantage of starting.

But the difficulty is not small.

Relying on his strong reaction talent, Zhang Peimeng took a lead of 0.03s at the start.

0.121s.

Xie Zhengye and Zhou Bing were simply out of reach in this area, as their starting reaction speeds exceeded 0.150.

That means we haven't taken the first step yet.

Both of them have lost 0.03.

You lost a position on the footrest.

The bent-arm start is not a panacea.

If your strength is not enough and your reaction time is not fast enough, you may still be suppressed by a straight-arm player who performs better.

You have to remember any technique.

All need to be able to be brought into play.

The bent-arm start technique that was only implemented for these two people this season is simply impossible to cause any trouble to real masters.

Zhang Peimeng is now an athlete with a score of 9.80+.

Even if the wind speed is good or the terrain is good, there are people who can break the 9 speed barrier.

How could it not be strong?

He is now one of the strong contenders for the top eight in the World Series.

You could say he was in the final round of the World Series.

Not very competitive.

There isn't much competition.

But there is a qualification.

That is why there is no competitiveness on the final stage of the World Series.

What are the world championship finals? Basically, there are only the Olympics and the World Championships.

This is in these two top competitions.

They are not that good looking, that's because there are too many super masters in this era, but even so, their strategic goal is basically to reach the finals.

Getting in at least means you are among the top eight in the world that year.

The top eight in the world versus the players ahead of them, especially the medal winners.

That's probably not worth mentioning.

But if.

Once it's not on the stage of this world competition.

Then their combat effectiveness will be greatly restored.

Even if it is compared with many Diamond Leagues.

The giants and quasi-giants are not here.

They can then secure medals.

It's even possible to win the gold medal.

They have actually reached the level of world-class players, but they are not yet top-notch.

Not quite the top.

Can deal with people like Xie Zhengye and Zhou Bing.

There aren’t too many players that specialize.

I'm not afraid at all.

Even if it’s Xie Zhenye, what’s the point of him running under 100 in the 10 meters?
Now that 10 seconds has just been broken, it is no longer the same as in the last 10 years. The degree of shock...

Much lower than it was 10 years ago.

If it was 10 years ago.

you could put it that way.

Whenever I see any hope.

Then the entire media will be eager to take action.

All kinds of bragging.

Various reports.

That is absolutely indispensable.

Even if you actually broke 10 seconds.

That compliment will feel like snowflakes.

It's impossible to count where it came from.

But now?
Even if you open it for 10 seconds, people will just cheer for you.

Then calm returned.

Everyone goes back to their own homes, each looking for his own mother.

Because of the threshold of domestic audiences.

It also closely connects with international audiences.

With their domestic achievements, Su Shen and his team can be said to be making great strides every year.

It must have felt fresh at the beginning.

It feels very exciting.

But further on.

Then it won’t be exciting anymore.

Even though Xie Zhengye had just opened it for ten seconds, he entered a group that was said to be even smaller than those who had been to space.

He was originally full of confidence.

Thinking about breaking 200 seconds for 20 meters and 100 seconds for 10 meters.

He is already considered one of the most versatile people in Asia.

Since it has been open for ten seconds, it still counts as being open, so I have become the number one 100-meter figure.

How to know.

I found out after I came in.

The 10-second mark is really just the beginning in front of true masters.

Only when you come in can you see how the real masters compete.

Zhang Peimeng used his improved straight-arm start combined with his evolving third-gear start and his own super reflexes.

He actually surpassed Zhou Bing and Xie Zhengye who started with bent arms from the very beginning.

Even Xie Zhengye was just feeling proud and complacent.

Want to try my own methods.

After all, the entire Ersha Island.

There are not many people who master this technology.

Even if people outside say that this is called "Ersha Island specialty", it doesn't mean that it is really a specialty.

In fact.

There are only five people in the entire Ersha Island who can master this technology, including the women.

If you don't count the women, there are only 4.

Plus the advantage that the bent-arm start brings him in international competitions.

Especially in the 200-meter range.

Xie Zhengye was a little bit proud.

pity.

It was immediately shattered by the cruel reality.

Damn it.

How come I can't run faster when starting with bent arms than when starting with straight arms?

Xie Zhengye was a little confused.

Because once he went out, he felt suppressed.

This is direct suppression.

No excuses for you.

Even Xie Zhengye was suppressed, let alone Zhou Bing.

As they started, Zhang Peimeng firmly held down one end.

This season, Lao Zhang...

sure.

It is actually possible to force a bent-arm start in the starting position.

There is something.

Even Yuan Guoqiang and the others couldn't help but nod secretly after seeing it.

Because this is really awesome.

This also shows that Zhang Peimeng has taken the right path here, and he updated the second gear start to the third gear.

His starting ability has been strengthened again.

The fact is that he doesn't run 60 meters very often now.

otherwise.

I'm afraid even Wen Yongyi can't suppress him.

Not to mention starting, Xie Zhengye was firmly suppressed, and he showed his power at the peak of his power.

Zhang Peimeng exploded.

The start is fierce.

Even Zhao Haohuan was almost killed when he started.

In other words, even Old Zhao only persisted a little.

Because apart from the moment you come out, if you take a few more steps, the disadvantage of height at the starting point will be revealed.

In other words.

Wen Yongyi did not make it to the finals this time.

With the help of his super reaction, Zhang Peimeng was able to do it in one breath.

I held down several bent-arm starts.

You can say that Zhao Haohuan’s height is too high. There is nothing he can do. Not everyone is Bolt. It is difficult for him to greatly improve his starting ability compared to running.

Over 1 meters tall.

The difficulty of natural startup increases exponentially.

The difficulty of shifting the center of gravity increases exponentially.

But Xie Zhengye and Zhou Bing are very different.

The two of them were also crushed.

Zhang Peimeng even had some intention of taking the lead.

This almost made the Lakers and Celtics excited at the scene.

This year, my junior brother used his straight arms to start and overpower his opponent's bent arms.

It's quite extraordinary.

but.

Xie Zhengye and Zhou Bing were a little anxious, perhaps because they were not strong enough and had not established the advantage of the bent-arm start.

Zhao Haohuan had none of that.

For him, it is enough for the startup to narrow his disadvantage.

He didn't think there would be no solution ahead.

There is only one person in history who is over 1 meters tall and can be extremely powerful at the starting end.

There is only the man called Bolt.

Therefore, except for the fact that he is an alien, for other players who are over 1 meters tall, it is enough for them to try to minimize their disadvantages at the start.

Wouldn't think too much here.

Zhao Haohuan took advantage of the strong wind speed in Eugene to blast 1 seconds for the first time.

It also makes his heart extremely strong now.

Unless you are facing a giant.

Even if facing a quasi-giant level.

He wouldn't be panicked.

Now he is an athlete with rich experience, honors and an impressive resume.

Don't try to shake his mind easily under any circumstances.

Especially those who are not as strong as him.

It was even more difficult for him to look at it twice.

Zhao Haohuan just needs to do his own thing.

Zhang Peimeng also felt that his shot had started extremely well.

Seeing these athletes who started with bent arms being strongly suppressed by him, he felt a little moved.

Do I have to take the first place in the starting position?
Of course.

impossible.

Because even if he suppressed Zhao Haohuan, who was too tall to start, and suppressed Xie Zhengye and Zhou Bing, who had just learned how to start with bent arms, he could not be said to be the first.

Because there was still one person he didn't suppress.

Can't suppress this person.

It is impossible for you to get first place at the start in domestic competitions.

This person is none other than the one in the middle...

Su Shen.

When human muscles exert force, the positional relationship between the line of force and the rotation axis of the limb affects the moment of inertia.

When the line of action of the muscle force is far away from the axis of rotation, according to the principle of the lever arm, a larger torque will be generated, which can more effectively change the rotation state of the limb.

Just like Su Shen is now.

Start up instantly.

Muscles contract at high speed.

Because rapid muscle contraction can generate greater force, this plays an important role in changing the moment of inertia.

Rapid muscle contraction generates powerful explosive force, which rapidly increases the angular velocity of the limbs.

According to the definition of moment of inertia, when a limb rotates rapidly, the mass distribution will change due to muscle contraction, the mass close to the axis of rotation will increase relatively, and the overall moment of inertia will decrease, which will be more conducive to rapid rotation of the limb. This shows that muscles affect the moment of inertia by changing the mass distribution.

Listen to the gun.

Stretch.

Take a step forward.

When Su Shen swings his arms, the shoulder muscles act on the upper arm through a longer lever arm, causing the upper arm to rotate around the shoulder joint.

At this time, the larger lever arm allows smaller muscle force to produce a larger rotational effect, which is equivalent to increasing the effect of the moment of inertia to a certain extent.

This is because the moment of inertia is related to the moment arm and mass distribution.

This is why Su Shen did this now.

Because my previous body simply couldn't do this.

The muscle mass in the back is not connected to the upper part of the triceps in the flexion start.

If you force yourself to do something, you will only bring trouble upon yourself.

After all, the greater the moment of inertia, the more difficult it is to change the rotational state of an object, and the muscles need to generate greater force.

For example, when doing a heavy barbell bench press, the system composed of the barbell and the arms has a large moment of inertia, and the arm muscles need to generate a lot of force to rotate the barbell around the shoulder joint.

In contrast, when doing light dumbbell bench press, the system has a small moment of inertia and it is relatively easy for the muscles to exert force. This shows that the size of the moment of inertia directly affects the difficulty of muscle force.

To put it simply - muscles need to adjust the degree of force according to the size of the moment of inertia.

Different moments of inertia require muscles to use different force generation methods. For objects with smaller moments of inertia, muscles can use fast, explosive force generation methods to achieve rapid rotation. For example, in the fast smash action of table tennis, the moment of inertia of the arm is relatively small, and the muscles generate explosive force through rapid contraction, so that the racket obtains a high angular velocity, thereby hitting a fast and powerful ball.

For objects with a large moment of inertia, muscles need to use a more continuous and stable force generation method. A typical example is when throwing a shot put. Due to the large mass of the shot put and the large moment of inertia of the system, athletes need to use continuous force from multiple parts of the muscles such as the legs, waist and arms to gradually increase the rotation speed of the shot put in order to achieve an ideal throwing effect.

Now that I have more muscles, I have more strength.

This adjustment of the moment of inertia.

It must also change.

Moreover, changes in rotational inertia can cause adaptive changes in muscles. When a certain rotational inertia is exercised for a long time, the muscles will adapt by increasing the number of muscle fibers and improving muscle contraction ability.

This adaptive change is a self-adjustment of muscles under long-term mechanical stimulation related to rotational inertia to improve athletic performance and efficiency.

These are done.

You can proceed to the next step.

That is the golden ratio in the composition and decomposition of forces.

The next step in using your muscles to achieve the golden ratio effect.

When the arm swing direction and the leg pushing force direction meet a certain angle relationship.

And this angle is related to the golden ratio.

It can maximize the direction of the body's forward movement.

Next is the golden ratio of energy efficiency.

From the perspective of energy utilization efficiency, the golden ratio effect in the bent-arm start is reflected in the coordination of movements of various parts of the body and the smoothness of energy transfer.

When the arm and leg movements are coordinated according to the golden ratio, the transfer of energy between various parts of the body is more efficient, reducing energy waste.

Just like it is now.

Swing your arms as you step forward.

The energy from Su Shen's arm swing can be effectively transferred to his legs through the rotation of his body.

Enhance the leg's pushing force.

At the same time, the reaction force generated by the legs pushing against the ground can also better promote the swing of the arms.

Form an energy recycling system.

This method of energy transfer and utilization based on the golden ratio enables athletes to achieve maximum exercise effects with minimal energy consumption during the starting phase.

When the arm's moment of inertia is optimized through the golden ratio, energy is transferred more smoothly between the arm and the body.

The angular momentum generated by arm swinging can be more effectively converted into the body's translational kinetic energy, reducing energy loss during the transmission process.

This optimized mechanism of energy transfer and conversion helps to improve the efficiency and speed of the start, allowing Su Shen to gain a greater advantage in the starting phase.

Bang bang bang bang bang bang bang.

Seven steps in a row.

Bend your arms to activate the golden section effect.

Fully activated.

The moment of inertia during the startup phase is further mobilized!
The mutual synthesis of forces in the startup phase is further mobilized!
The energy utilization rate during the startup phase is improved!

Su Shen took a violent step forward!

Ten meters passed in a flash!

Increase the swing arm!

Due to the characteristics of the plateau, we can do things that cannot be done well in the plains.

The acceleration zone begins.

Vertical displacement is stable!

Only Su Shen was seen.

Mobilize the principle of conservation of angular momentum.

According to the law of conservation of angular momentum, when there is no external torque acting on the human body during movement, the total angular momentum remains unchanged. The arm swinging action generates angular momentum in the opposite direction of the lower limbs and trunk by changing the moment of inertia and angular velocity of the upper limbs, thereby maintaining the overall angular momentum balance of the body and helping to stabilize vertical displacement.

When running, the arms swing forward, increasing the forward angular momentum of the upper limbs. At the same time, the lower limbs push the ground backward to generate backward angular momentum. The two offset each other and prevent the body from excessively rising and falling in the vertical direction.

Increased vertical displacement stability.

The interaction principle of regulating force.

During the arm swing, the accelerated swing of the arm will generate a force. According to Newton's third law, there will be an equal and opposite reaction force acting on the body. This reaction force can adjust the position and movement trajectory of the body's center of gravity. In the vertical direction, the appropriate arm swing reaction force can offset part of the vertical impact force generated by the lower limb movement, making the vertical displacement of the body more stable.

Rely on swinging your arms to change the position and movement state of your upper limbs.

Adjust the position of your body's center of gravity in real time.

Increased vertical displacement stability.

Rely on the contraction of the arm swing muscles to stimulate the nervous system, enhance coordination with the lower limb muscles, and improve the consistency and efficiency of muscle force.

One of the specific manifestations is that when accelerating, whenever Su Shen's body tends to fall forward, swinging his arms backwards quickly can move the center of gravity backwards.

This restores balance.

Twenty meters passed in a flash!

Su Shen was so fast that it seemed like there was no limit to his speed.

It seems to get faster every time.

will be stronger.

Will break the limit.

Just like this position.

A position.

Even several body lengths.

Pull it apart half a meter at a time.

The audience seats were filled with noise.

The cheers were instantly brought to a climax!
Also, because on the plateau, the appropriate swing arm amplitude has a significant impact on the vertical displacement stability.

The range of arm swing is mainly determined by the flexion and extension range of the shoulder joint.

When the body tends to be unbalanced in the vertical direction, such as leaning slightly forward, Su Shen immediately increases the amplitude of the backward arm swing.

This is to generate greater reverse torque.

From the perspective of muscle work, at this time the posterior deltoid, latissimus dorsi and other shoulder extensor muscles contract strongly, driving the arms to swing backward significantly.

According to the principle of leverage, the arm is like the long arm of a lever, with the shoulder joint as the fulcrum. A larger swing will produce a larger lever arm. According to the torque formula M = F×L, M is the torque, F is the force, and L is the lever arm.

Generate a greater reverse torque to balance the body's tendency to lean forward.

Re-stabilize vertical displacement!

Bang bang bang bang bang.

Twenty-five meters.

Vestibular signal calibration.

The human body's vestibular system is responsible for sensing changes in head position and movement and is essential for maintaining balance.

This is especially true on the plateau.

A good arm swing provides an additional calibration signal to the vestibular system.

When you swing your arms, the muscles and joint receptors in your shoulders and arms generate proprioceptive signals, which are integrated with the head movement information sensed by the vestibular system.

The proprioceptive signals generated by arm swinging can help the vestibular system more accurately judge the angle and speed of head rotation.

Correction may be caused by high altitude environment interference.

For example, wind affects perception.

Too many buffs and too strong.

In fact, it can easily lead to vestibular signal deviation.

What Su Shen wants to do now is to use arm swinging to allow the brain to have a more accurate understanding of body posture.

Thereby continuing to maintain vertical displacement stability.

The speed in the acceleration zone is getting faster and faster.

There is an increasing need for stabilization of vertical displacements.

Bang bang bang bang bang.

Vestibular-ocular reflex synergy.

Arm swing is also involved in the coordinated process of the vestibular-ocular reflex, or VOR.

During plateau exercise, there is a certain correlation between arm swinging and head movement, and the changes in body posture caused by arm swinging will indirectly affect head movement.

When swinging the arms causes the body to shake, the vestibular system senses the movement of the head, triggers the VOR, and causes the eyeballs to move accordingly to stabilize the vision.

At the same time, the proprioceptive signals generated by a good arm swing will be fed back to the nervous system, further adjusting the gain of the VOR, that is, the proportional relationship between eye movement and head movement, so that the visual stabilization mechanism can better adapt to the body's movement state and avoid body imbalance caused by visual instability.

Ensure visual stability in the vertical direction.

All of these have been done.

Excuse me.

Su Shen is on the plateau.

How can the vertical displacement stability be low?

How can we understand vertical force, an important force in sprinting?

Is it not used well?

well.

Off to a good start.

Su Shen himself also felt it.

He gradually raised his head.

In the eyes.
