Work and rest vs. Zhang Peimeng.

This is the focus battle of the day's test.

Both of them also fought hard.

“Each is in place.”

The two looked at each other without saying much.

Start to dry directly.

Over the years, the two have had a tacit understanding in their struggles.

"preparation."

Today's surprises and prestige are one after another.

Everyone is looking forward to it.

What is the result of this ultimate battle?

Should I take the time to avenge my previous shame or Zhang Peimeng continue to maintain his advantage?

Bang—

Gunshots rang out.

Two people rushed out at the same time.

In an instant, everyone was attracted by these two people.

It involves energy.

In terms of starting reaction, Zhang Peimeng is naturally better. There is no point in saying that having the talent to start reaction is one of Zhang Peimeng's original talents.

Even Su Shen conducted scientific training in all aspects.

It also does not meet this level.

Can hold him in this place.

Throughout the history of Asia.

Maybe there is only the gun-repressing maniac, Shanxian Liang is too much.

The first step is to go out and land.

Standard four points and one line.

Ankle, knee, hip and shoulder.

Connected into one.

first step.

The posterior tibialis muscle takes the lead in exerting force. When it contracts, it can help the ankle to produce internal rotation. This is like installing an accurate steering device on the ankle, laying the foundation for the reasonable conduction of subsequent forces and the smoothness of footwork.

This allows the first step to take a suitable angle and direction of force.

The key lies in the preparation for force at the ankle.

Zhang Peimeng made three points better than last year.

This shows that even though he made a breakthrough last year, he still did not slackew at all. He has been on Ersha Island for so many years and has long been the same as him on the original timeline.

The point of being careless and careless, liking to have fun, and liking to live is no longer related to his current situation.

He has been completely polished into a professional-level world athlete with a tough and steady mind.

At the same time, the longus peroneal muscle contracts, helping the ankle to produce external rotation, and cooperate with the internal rotation of the posterior tibialis muscle, so that the ankle can flexibly adjust its posture and adapt to the instantaneous power changes and physical balance needs at the start.

Then, the longus flexor thorn muscle is also contracting at this time. Its important role is to maintain the arch shape and stabilize the foot structure, just like building a solid "foundation" to ensure that the strength can be effectively transmitted upward from the soles of the feet, and there will be no loss of force or unstable foot support.

Su Shen nodded silently when he looked at it.

The function of the first step is the ankle movement and stability in the early stage of the starting point. It is the starting point for subsequent acceleration. Good ankle force and posture control can give a good start for the entire starting acceleration process and create favorable conditions for subsequent strength to be transmitted to other parts of the legs.

Zhang Peimeng did a good job.

Even if he looks.

The same is true.

Step 2.

The gastrocnemius muscle is beginning to play a key role.

It shrinks, providing strong propulsion to the ankles, which pushes the body forward and moves quickly, as if installing a powerful "booster" on the body.

On the basis that the posterior tibialis, peroneal longus and flexor longus have prepared for the ankle, the gastrocnemius muscle further amplifies the strength and converts it into forward propulsion, so that the speed can be rapidly increased, achieving a gradual transition from the initial starting state to the acceleration state.

Among the traditional four golden steps, the second step is to have enough strength to get rid of stillness and quickly obtain forward speed. The propulsion provided by the gastrocnemius muscle is the key to achieving this goal. It undertakes the power of the previous coordinated preparation of various muscle groups at the ankle, and converts it into actual acceleration power, pushing the body to accelerate forward within just a few meters.

Step 3.

The ankle is the center, and the force generated by the force exerting force of the four muscle groups at the ankle begins to spread and stimulate the four muscle groups around it.

At this time, the quadriceps femoris begin to contract.

As the most important extensor of the knee joint, the quadriceps femoris mainly serves to straighten the knee joint. When actively contracting isometrically, it can help stabilize and protect the knee joints, ensuring that the knee joints will not experience unnecessary shaking or uneven stress during high-speed running, and ensuring the coherence and stability of the body forward.

At the beginning of the third step, the body's requirements for knee joint stability are getting higher and higher. The quadriceps muscles stabilize the knee joint through equal length contraction, allowing the body to maintain a good force posture while continuing to accelerate, avoiding the risk of strength loss or injury due to knee instability, and protecting the escort for further increasing speed.

Step 4.

The centrifugal contraction function of the quadriceps femoris becomes particularly important. When it undergoes centrifugal contraction, it can control the speed of the body's decline.

This will help adjust the body posture when it is about to enter the acceleration process, better deal with the connection between landing and pushing the ground, and ensure that every force can be efficiently converted into forward momentum.

Make the speed more smoothly in the final stage of starting.

It can be seen that Zhang Peimeng should have strengthened his ability to centrifugal contraction of the quadriceps muscles.

This can accurately control the body posture and strength during the sprint stage. The centrifugal contraction ability of the quadriceps can meet this requirement, allowing the first 10 meters of the starting start to finish in the best condition, helping Zhang Peimeng gain the maximum speed advantage possible during the start stage.

Zhang Peimeng’s golden four steps completely utilizes the four-point connection line, compared to when he first mastered it last year,

More based on the scientific laws of human body movement, from the feet to the legs, each muscle group plays its role in sequence and cooperates with each other.

Together, push the body from stillness to quickly enter the sprint state of high speed.

Every stage is indispensable.

The force characteristics and functions of each muscle group are closely related to the efficiency and quality of starting acceleration.

Zhang Peimeng's mind has indeed been tempered.

Will be stronger.

His talent.

Never doubt.

With the wind speed not too high, you can play your best state on the stage of the World Championships and almost open it for 10 seconds. This is already a traditional system. Although the water and wood system is no longer so traditional, it still seems not advanced enough when compared with the real scientific system.

With this background, this is still one of the strongest performances in China many years, and it is not even worse than those young people who have undergone scientific training.

Just temper your mind and nature well.

Zhang Peimeng's talent.

Su Shen really never worried much.

Start with your unique second-level.

Zhang Peimeng’s ten meters.

It is necessary to get rid of the work and rest!

Work and rest will inevitably be suppressed this year and completely throw it away!

that is……

Things develop.

It is not as beautiful as Zhang Peimeng thought.

It's not as beautiful as Hu Kai thought.

Because of the voice behind me...

Remind him all the time.

They are right behind them.

Not quickly thrown away.

"How could that happen?" Hu Kai looked at it, his expression was a little frozen. He knew that Zhang Peimeng had made progress again this year.

Start-up has never been a strong point for work and rest.

How is it possible? Zhang Peimeng has made great efforts this year, but he still hasn't gotten away with it. There are too many work and rest?

This is too unreasonable.
