"You boy is really brave." Wen Yongyi also said: "Although I asked you to defeat me, I will not let you go."

"And I said to defeat."

“It may not be this year.”

"If you lose, you have to listen to me scolding you honestly."

"Okay." Xu Zhouzheng also nodded.

At this moment, the scene was cleared again and the track returned to the silence before the gunshot.

The two people's grades are actually similar.

This year is also the time when Xuzhou, which has been developing for another year, is about to increase its performance.

This way.

It's really not that there is no chance.

Choose the veteran first-team player of Fengwen Yongyi.

Of course, more people are optimistic about Wen Yongyi, and Xuzhou has great potential. But it shouldn't be able to win now...

This chapter is not over, please click on the next page to continue reading! "Everyone is in place."

"preparation."

Bang------

Gunshots rang out.

The two rushed out quickly.

The impression of most people is that Xuzhou is still at the 10.27s of the World Youth Championship last year. This result is good among young people, but...

Put it in the professional team, especially the first team of Ersha Island.

It's very ordinary.

There is no highlight at all.

However, everyone saw different things at the beginning.

The fit angle between Wen Yongyi's feet and the starting machine is accurate to a slight slight, and the adjustment is made according to his own strength characteristics and the distribution of the body's center of gravity.

The moment of starting, the rear pedal movement was extremely smooth.

He is worthy of being a winner of the World Indoor World Championships.

Looking at Asia, few people can suppress it except Su Shen.

Specializing in 60 meters also makes his technical characteristics more perfect than 60 meters.

His hip, knee and ankle stretches follow the best order of force.

The hip joint first exerts force, which drives the muscles of the back of the thigh to contract and provides initial power for the overall back pedal.

The knee joint is stretched accordingly, fully releasing the strength of the quadriceps.

Plantar flexion of the ankle joint is like the final acceleration engine, ensuring that the force is transmitted to the ground intact and efficiently, forming strong propulsion.

At this level, there are not many people in Asia who can take over except Su Shen.

But Xu Zhouzheng, a seventeen-year-old guy, is not nervous.

His pedaling method of starting the machine has been polished over the years. The pedaling force of his feet is evenly distributed and precisely, ensuring the stability and explosive force balance at the start moment.

During the center of gravity transfer process of starting, he cleverly utilized the coordination and cooperation of various parts of his body.

The downward pressing action of the forefoot is accompanied by the elastic contraction of the calf triceps, like a combination of a precision buffer and an accelerator, effectively receiving and converting power.

When the rear foot is stretched, the gluteus maximus, quadriceps and calf triceps explode together to form a complete chain of strength.

There is not much difference between Wen Yongyi in starting up.

After seven steps.

Start entering the acceleration zone.

When Wen Yongyi accelerated, he gradually increased his stride through the nervous system's fine regulation of muscles. The increase in span of each step is not blind, but is adjusted according to the dynamic changes in speed and body balance.

Experienced and experienced at a glance.

Xu Zhouzheng's acceleration is a subtle interpretation of the balance of speed and power. His acceleration process is a layered and ordered dynamic process.

In the early stage, he quickly increased his speed through short and fast pace, which was due to his ability to quickly contract and relax his calf muscles and his ankle flexibility.

As the speed increases, he gradually lengthens the stride, which involves the linkage of multiple joints of the lower limbs.

This is also what he is good at.

Twenty meters and thirty meters.

Bang, bang, bang, bang, bang.

Although Wen Yongyi is slightly better, the gap is smaller than expected. What level, age and experience in Wen Yongyi?

It is enough that a 17-year-old Xiao Chu brother in Xuzhou can achieve this level.

It fully reflects his potential and the optimistic attitude of Randisu.

Most people really can't keep up.

Then he started running on the way.

Wen Yongyi's stride frequency is maintained in a stable and high-speed range. This coordinated change between stride and stride frequency is based on the result of complex motion model calculations. He has optimized it many times, which is already a test-printer.

As Xu Zhou stretched his stride, the extension range of his hip joint gradually increased, and the angle and speed of the thigh swing were adjusted in real time according to the movement of the body's center of gravity.

Another ten meters, Wen Yongyi takes the shoulder joint as the axis and strictly follows the mechanics of human body movement. The moderate amplitude of the arm swing can not only provide enough rotational power for his body, but will not destroy the body's balance due to the excessive amplitude.

It looks like a very mature running system.

Although Xuzhouzheng looked a little unfamiliar, he did not hesitate. In terms of how the soles of the feet were hitting the ground, the forefoot was hitting the ground at the beginning of acceleration, and as the speed and strength increased, it transitioned to the full foot landing. During this process, the friction between the soles and the runway reached a good upper limit.

Then.

Both of them began to explode at a very fast speed.

It seems that Wen Yongyi is still far ahead here.

But Su Shen could see that the offense and defense had begun to change easily.

Because Wen Yongyi's speed is never enough.

Xuzhou's talent is much better in this regard.

"Ayi, you may lose." Just as everyone was nervous and evenly watching.

Su Shen suddenly spoke.

Then, it was exactly what Su Shen expected.

The situation took a sharp turn for the worse.

Xuzhou is skillfully controlling the time and strength of the ground, and he transformed the reaction force on the ground into a continuous acceleration power.

At the same time, fine-tune the double requirements of the body's forward angle and body balance, maintain the best streamlined posture, and minimize the obstacles to speed increase by air resistance.

The more you enter the back, the more than sixty meters it is, the more obvious it is.

Wen Yongyi devoted more to 60 meters and ignored the back. From here, he was a veteran. After 60 meters, he was not as good as a 17-year-old newcomer.

Even Wen Yongyi's angle and speed of the front and back swing arms have been trained countless times to form muscle memory, and has formed a highly coordinated coupled movement with the leg movements.

But... it's forty meters behind him.

It's really too dishy.

It has never been very good.

Both Joyina can fight back and forth.

Therefore, even if muscle memory is formed, it is highly coordinated and coupled with leg movements.

However, the plate is not high.

No matter how skilled you are, it is useless.

Instead, they began to be constantly pursued and their advantages were constantly eroded.

Eighty-ninety meters, Xuzhou has already come up.

Wen Yongyi and Xu Zhouzheng ended up trying their best.

Pressed towards the front key line.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

both sides.

They all leaned over and pressed the line.
