Bang—

Gunshots rang out.

Four people rushed out from the starting line at the same time.

The fastest ones were Xie Zhengye and Zhou Bing.

The two of them set up their arms and started running.

Xie Zhengye's chemical energy in the human body is converted into mechanical energy through muscle contraction. At the start, muscle contraction drives the arm to swing quickly, and this rapid mechanical movement transmits energy efficiently to the entire body. From a biomechanical perspective, the frequency of muscle contraction is matched with the arm's bent arm driving frequency, providing continuous power for starting acceleration in the form of high-frequency energy output. It is like an efficient energy transmission chain, ensuring that energy is quickly and continuously converted into forward kinetic energy.

Zhou Bing, when his arm swings greatly, according to the law of conservation of momentum, the body will obtain a larger reverse momentum as a whole, which is further utilized when the legs are stretched. During the stretching process, the leg muscles are affected by the momentum generated by the swing of the curved arm, and can exert their strength more fully, thereby increasing the stride.

Moreover, compared with Xie Zhengye, in terms of energy conversion, Zhou Bing's arm swing during starting requires more muscle energy reserves. When the muscles contract and stretch greatly, they convert a large amount of chemical energy into mechanical energy. Unlike Xie Zhengye, his energy is more concentrated on a single, larger-scale movement to ensure that the legs have enough strength to stretch at the start and achieve a larger stride leap.

The separation was not so obvious before.

Put it together now.

The comparison is more intuitive.

Compared with Xie Zhengye, before starting, Zhou Bing adopts a squat starting position that is more conducive to leveraging his stride advantage. The distance between the front and back of his feet, the degree of knee bending must be accurately adjusted according to his physical conditions and habits to ensure that he can obtain the maximum forward thrust at the start.

The center of gravity of the body should be moved forward as much as possible, like a tightened spring, accumulating strength for the big stride after starting.

He bent his front knee to about 90 degrees and his rear knee bend angle was slightly smaller, so that he could better utilize the explosive power of the leg muscles at the start and lay the foundation for the subsequent stride advantage.

After starting, the swing of the arm should be closely coordinated with the movements of the legs. When the arm swings back vigorously, it will drive the body to move forward and upward, and the legs should take greater steps.

When Xie Zhengye starts with a bent arm, his arm swings frequency is high. At the moment of starting, rapid arm swing can drive the body forward quickly and provide strong power for acceleration after starting. For example, in the first few steps after starting, he quickly gains forward propulsion through high-frequency arm swings, allowing his body to quickly enter the acceleration state.

When starting with a bent arm, the movements of the arm can help Xie Zhengye better coordinate the balance of the body. During the high-speed starting and acceleration, the balance of the body is very important, and a slight imbalance may affect the speed. A fast swinging arm can help the body maintain stability to a certain extent, allowing the legs to exert force more effectively, thereby achieving rapid start and acceleration.

Secondly, from the perspective of efficient power transmission - Xie Zhengye's posture of bent arms can better transmit the strength of the arm to the core part of the body, and then pass it to the legs through the core part, thereby enhancing the explosive power of the legs.

This kind of power transmission is coherent and efficient, which can enable Xie Zhengye to quickly increase his speed in a short time after starting. For example, at the starting stage of the competition, his bent arm movement can quickly transmit the strength of his arm to his legs, making his starting speed significantly better than before.

At the same time, the swing of the bent arm of the arm is closely coordinated with the movements of the legs to form a coordinated movement system. During the start and acceleration, the swing rhythm of the arm is echoing the rhythm of the legs and the pushing rhythm of the legs, providing strong power for the body.

This cooperation makes Xie Zhengye's overall movements smoother and his explosive power can be fully utilized.

Because the two of them are on the way.

This time, although it seems that they all start with a bent arm.

But the gap is extremely obvious.

This is also the unique charm of everyone's technical training.

It is not like carving out of a mold like an assembly line. Instead, it is based on the same scientific concept, and the characteristics of personal physiological conditions are upgraded.

This is also the fascinating feature of sports science.

Compared with Zhou Bing, Xie Zhengye: Xie Zhengye's starting posture is relatively standard and stable. He stands with his feet forward and backward, the bend angle of the front knee is about 90 degrees to 100 degrees, the bend of the back knee is slightly smaller, the body leans forward, the center of gravity is forward but maintains balance. This posture can make the body store and release greater elastic potential energy at the moment of starting, converting it into forward kinetic energy, helping him to quickly start his arms.

Then rushed out.

Center of gravity shift.

During the starting process, he can accurately control the smooth transfer of his body's center of gravity. From the preparatory position to the first step of starting, the center of gravity gradually moves forward and upward. At the same time, he can cooperate with the legs to extend and swing the arms to enable the body to quickly accelerate along a straight line, reduce energy dispersion and unnecessary lateral shaking, and improve the efficiency of starting.

In addition, Xie Zhengye's shot responded faster.

He is on the start.

It took the lead.

Suppressed Zhou Bing.

Although Zhou Bing was also surprised that Xie Zhengye, a little brat, had mastered the bent arm start so quickly that it took him so many years to achieve a breakthrough...

But he still had the intention of competing.

There is no way to compete.

All are the same startup actions.

How could it be that it is not comparable to the previous one?

In the first four steps after the start, Xie Zhengye used his high-frequency arm swing to drive his legs to alternate quickly.

The arm swings rapidly and rhythmically. Each swing forcefully pushes the body forward, allowing the legs to take steps at high frequency. At this stage, his stride is relatively small, but due to the extremely fast pace frequency, he can reach a higher speed in a short time, quickly complete the initial acceleration of the start, quickly expand the gap with his opponent within a short distance after the start, and seize the lead position.

Here, Xie Zhengye relied on his bent arm to start and got the frequency of the start step increased.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! You can see that his first four steps are coherent and compact, and his body leans forward angle is appropriate, like a tight bowstring.

Full of speed.

Zhou Bing's first four steps after starting, his arm swings was relatively large, and the focus was on creating good conditions for exerting force on his legs to increase his stride.

His first step is to steadily send the center of gravity forward and upward through the powerful swing of his arms and the kicking of his legs. The subsequent three steps gradually increase the stride.

This made him not as fast as Xie Zhengye’s speed in the first four steps, but the distance of each step was gradually increasing, laying the foundation for the subsequent larger strides.

Unexpectedly, he followed Su Shen and Zhao Haohuan.

The two people started a war of bent arms.

Unlike Su Shen and Zhao Haohuan's group, Su Zhao's previous activation ability is too big and the height difference is too big. It is not suitable to put it together.

Xie Zhengye and Zhou Bing are both 200-meter players.

The confrontation is even more incomparable.

Because the rest of the people did not have the ability to start with a bent arm, the entire golden four steps plus the start of the first 10 meters became the confrontation stage for Zhou Bing and Xie Zhengye.

Even Liang Jiahong.

I can't get involved here either.

As the number of steps increases, Xie Zhengye still maintains a higher step frequency, and the coordination between his arms and legs is also smoother because of the speed.

At this time, his speed has increased significantly, and his body gradually entered a more stable acceleration state.

His stride may increase slightly on the basis of maintaining stability, mainly by further optimizing the coordinated movements of the arms and legs, and using the force generated by the arm swing to promote the legs to extend more fully, so as to continue to expand the advantages within a short distance after starting and prepare for the subsequent acceleration stage.

For Zhou Bing, the next few steps are a process of gradually enlarging the stride. The larger swing of his arm continues to provide power to his legs, making his stride larger and larger in these seven steps.

At five, six or seven steps, his stride advantage began to become more obvious. The distance he crossed each step was larger than Xie Zhengye. Although the speed may be slightly inferior in the early stage of the start, he has begun to gradually catch up at this stage.

Zhou Bing did not grow up with nothing to eat.

I have been practicing this technique for so many years.

In this link.

Compare Xie Zhengye.

Not much less.

All start with bent arms.

The development direction is completely different.

It's also a strange sight.

The moment Xie Zhengye started, the neuromuscular system was highly coordinated. His bent arm start technology showed typical high-step frequency characteristics, fast muscle fibers were activated quickly, and muscle contraction produced strong explosive power.

Zhou Bing's arm swing angle and amplitude have been carefully adjusted, and uses the centrifugal contraction and centripetal contraction of the muscles to generate greater momentum. This momentum is transmitted to the legs through the body's movement chain, providing strong support for leg slitting and stretching, thereby achieving a larger stride.

But it's only ten meters.

After ten meters.

As the acceleration zone began, Xie Zhengye began to suppress it significantly.

The pace frequency increases further with the speed.

In the past, the situation where the pace frequency was not enough has been greatly improved.

This stable high step frequency is due to the muscle isomotor contraction ability, making the force output even and efficient.

The swing of the arm is highly consistent with the rhythm of legs thrusting, forming a stable dynamic rhythm.

As the number of steps increases, the stride gradually increases under the driving force of a stable high step frequency, and the body's acceleration process is smooth and rapid.

Although Zhou Bing also wanted to continue to create greater kicking and stretching power for his legs and further expand his stride.

However, during this process, due to the need to adjust the center of gravity and movement posture of the body to adapt to the increase in stride width, the complexity of the movement leads to a slight decrease in stride frequency.

Although the pace continues to increase, the speed is gradually increased, the overall acceleration efficiency is slightly inferior to Xie Zhengye, and the speed improvement is slightly coherent.

So from twenty meters, Xie Zhengye gradually accelerated and pulled over.

If Zhou Bing could hear Xie Zhengye's voice, he would definitely be so angry...

Goodbye Pancake.

Sprinkle oil.

Zhou Bing was angry, but he didn't know how amazing what he had done now.

He was a person who used to make a living completely from the back.

At least most people think so.

Including Liang Jiahong.

Who knew that he would suddenly join Xie Zhengye here, and his future will start and greatly suppress himself.

Last year.

He is a winter training test.

Keep pushing everyone away.

Including Zhou Bing and Xie Zhengye.

Only Wen Yongyi was suppressed a little in front of me.

Ke Wen Yongyi specializes in 60 meters and is also the medal winner of the World Indoor World Championships. It is normal to compare him here.

Besides, after passing Wen Yongyi's level, the rest of them couldn't stop him.

I thought Wen Yongyi and Xuzhou had finished the same group.

My own group should be relaxed.

result……

Xie Zhengye and Zhou Bing.

He actually killed him in front.

Run again with yourself.

That's it.

These two are both people who are mainly in the future, and they are ahead of themselves. What's going on?

Liang Jiahong was so angry that he was just about to get angry.

He completed the full adjustment in winter training last year, which led to the impact of his start-up and acceleration, not as fast as before, but the consequence of this sacrifice is the full optimization.

Take the balanced route.

It became his choice.

Then if you choose this path, it is impossible to be the same as before. If you don’t see the ultimate balance of Blake, can you not get much advantage when you meet Bolt Powell, then?

I originally wanted to go further this year.

The technology is more delicate and the system.

The startup power has also been optimized...

The distribution of the power of the startup may not be reasonable enough, and some of the power was wasted or failed to fully play its role in the startup process. This winter training, after training, the forces of various parts of the body can work better together, focusing the power on the starting movements, making the explosive power of the startup stronger.

I thought it would be better.

Of course the facts are better.

But that's it.

These two bent arms start.

Suppressed all his sharpness.

It seems that he has no improvement.

This is really a shocking person.

Two players who are good at the back-range are suppressed by themselves in front. So how can they run?

Isn't this even more hopeless?

As a result, God is still fair.

In other words, these two people just mastered the curved arm and started, and many things were in a state of gain and loss. For example, Zhou Bing was a bit similar to Zhao Haohuan, who had just started to master the curved arm, and the benefits obtained from starting to acceleration decreased rapidly.

Now all his focus is on using this technology from actual combat.

The rest hasn't considered that much.

The most important thing is that his own strength is not that strong. He finally got a strong man before, but he still had to fall back or he had to fall back.

Liang Jiahong saw Zhou Bing's speed decrease.

Take a rush immediately.

Similar to Zhou Bing, Xie Zhengye's speed has also dropped.

But Xie Zhengye is stronger.

The decline here is not that big or obvious.

But they were also captured by Liang Jiahong.

This immediately made him happy.

How can I play the next table?

If you cannot establish a leading trend ahead, it is really hard to say later.

In fact, it can be seen that Liang Jiahong has made absolutely progress this year. Whether it is the starting position, the legs thrust, the arms swing, etc., it can maintain a high degree of consistency and stability. These are things that can lay a good foundation for subsequent acceleration and running on the way.

Because of this, he actually has ambitious this year.

Xie Zhengye is the first, Zhou Bing is the second, Liang Jiahong is the third.

But after entering the way.

The situation has changed a little.

Liang Jiahong's preparations have been made before, and now he has started to play the more delicate skills than last year, which also allows him to better distribute his physical strength while running on the way.

In the past, due to the large differences in abilities between the front and rear sections, the physical strength may decrease and slow down in the second half of the way. It was particularly prominent when fighting against Xie Zhengye last year.

In winter, he began to focus on strengthening. Now, all parts of his body can work efficiently and work in a balanced manner, and cardiopulmonary function, muscle endurance and other aspects have been developed.

This can maintain a relatively stable speed over a longer distance, reduce speed fluctuations, and make the entire journey more smooth and efficient.

at the same time.

His hip delivery finally began to faintly have the shadow of his own unique system. This is what every elite athlete needs to do if he wants to become a world-class athlete to become a further world-class athlete.

You cannot combine the technical system with your own unique style to form your own unique system.

It will be difficult for you to complete further transformation.

It is very likely that you will be stuck at a certain point and it will be difficult to make progress.

Liang Jiahong can indeed do it.

He is indeed a man who was delayed by bone cracks.

Now it's OK.

He is increasingly moving towards his ultimate talent.

Is there a chance to turn on for 10 seconds?

With the support of my scientific system and technology this time, can I have the opportunity to hit 10 seconds?

Su Shen wanted to know too.

40 meters 50 meters.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

During the 20 meters along the way, several people were showing their magical powers.

Seeing Liang Jiahong gradually began to catch up, Yuan Guoqiang's face also improved a lot.

Otherwise, he would be really worried.

Is this disciple already reaching the limit and unable to keep up with the progress of these large troops?

Extremely exploded.

Liang Jiahong has also done better here this year.

The stride and pace frequency of each step can reach the optimal joint point, the legs swing more forcefully, the grounding is lighter, and the forward angle of the body is more reasonable, reducing unnecessary energy consumption.

He still has more experience.

Come into contact with the Su Shen system earlier here.

With my own talent, it's pretty good.

Here I also played my best and made three points.

Xie Zhengye and Zhou Bing have both old problems.

Speed ​​is not good enough.

Instead, it entered the extreme speed.

He was crushed again.

"Is Ah Hong going to win?" Wen Yongyi said.

"It's hard to say."

"It's possible that the game has just begun."

Su Shen looked at him calmly.

He knew that the game was not that simple and it ended.
Chapter completed!
