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.

Actually, there is nothing unreasonable.

If you still remember the optimizations made by work and rest last year, you will know that last year, for the overall rhythm and the distribution of front and back, work and rest actually slightly suppressed the rhythm of the entire future. This is also to make it better to maintain the speed and speed, and the future has more energy to impact.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

Acceleration zone.

Zhang Peimeng started to start at a speed and started more powerfully. Of course, this place will have faster acceleration and enter the acceleration zone.

He didn't know how to do it when he started.

He didn't care how to do it either.

Because startup is just a start for yourself.

Your own startup becomes stronger, and it will inevitably make your acceleration area run faster in the future.

Sprinting is an overall project.

The front is soon, and it will also affect the back.

It's not something that is split.

Your own acceleration will definitely suppress work and rest.

Hu Kai also thinks so.

Last year, when Zhang Peimeng and Laoyi were in the winter test, they were distracted by Laoyi and Laoyi and followed him in front of him because of some distraction. This time, Zhang Peimeng did not make this problem again.

The competition is being taken seriously throughout the whole process.

Focus on completing your own technical process.

It can be ten meters later.

Another ten meters.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

I have run very smoothly and deserve the feeling I want to get from what I want.

But.

The sound of nails behind him.

It seems that there is no reduction in much.

Zhang Peimeng frowned slightly.

Even when running at high speed, facing such a situation, my expression begins to operate uncontrollably.

"Why? No, it shouldn't."

Seeing that the start-up was over, Zhang Peimeng did not establish the advantages he imagined.

Then let’s get the acceleration zone.

It's okay to build an acceleration zone.

But the acceleration zone has not been established.

Hu Kai was also a little stunned.

He clearly felt it.

What is the technology of not stopping work and rest?

It is not like Zhang Peimeng, whom he led, who has made a lot of technical improvements and has overcome various technical difficulties.

I can't even handle the four points of connection.

But there is a problem with this.

Many people actually couldn't get the four-point connection.

That doesn't prevent him from achieving good results.

Look at the players of Team USA.

Don’t everyone connect three points to the ground?

Why can people run so fast?

The development of technology naturally has different advantages and disadvantages, advanced and unadvanced. However, for those who use it, there are differences between suitable and inappropriate, there are differences between adaptation and inadequate, and there are differences between good use and poor use.

Work and rest here.

There is no way to go for technical flow.

Of course, the so-called failure to follow the technical flow here means not following those obvious technical levels.

It's not that he can run so fast now and has no technological progress.

Control of the body.

It is a basic technique in any competitive sport.

This basic technique is done well.

It can also reach a height.

There are some orders of technology, but there is no application.

Which one can develop its own physical limits?

Which one can achieve better results and be more comfortable to use on your own?

Then which one can be used.

What's more, work and rest have reached this age.

There is nothing that cannot be tried.

Last year, work and rest were used to support and offset the use of a strong core to prevent the retention of the rectus of the thigh when the rectus of the thigh is excessive, especially when the iliopsoas muscle is under too much force and too frequent, the hip flexion function will be reduced. At this time, the rectus femoris will overcompensate the hip flexion. As time goes by, there is a significant muscle pulling on the front side of the thigh, which will cause the tension reaction to slide and decrease, almost being pushed back.

It even enhances the body's tension response to increase the body's driving force.

Is this the same thing this year?

Of course not.

He is going to take out what he is now, but what Su Shen is using now.

It is called power chain integration!

"As the central structure of the body, the stability of the pelvis directly affects the running posture. The gluteus maximus, gluteus medius, gluteus minimus and pelvic floor muscles in the core muscles work together to stabilize the pelvis. The gluteus medius and gluteus minimus are mainly responsible for controlling the lateral balance of the pelvis when supporting one foot, preventing the pelvis from being too tilted to one side, and avoiding Trendelenburg gait."

"This gait is an abnormal gait in which the pelvic tilt caused by abductor muscle weakness and the body shakes left and right. The athlete happens to be weak in this place because the training intensity is too high or the sprint is too strong, which will cause fatigue in this place."

"First of all, we have to solve this gait."

"When running, especially when running on curves or accelerating direction, whether the pelvis is stable or not has a great impact on maintaining the body's straight running. A stable pelvis can make the lower limbs exert force more reasonably and ensure that the body advances in the expected straight direction."

“How to do it?”

“First is one-legged support balance.”

"During the sprinting process, the one-leg support stage is a time when the body's balance is easily broken. At this time, the core muscles need to be adjusted quickly to maintain balance."

This chapter is not over, please click on the next page to continue reading!…

This is what it means to do with one foot. Starting from the balance of support and balance, you can see that the ground reaction force transmitted from the soles of the foot begins to pass through the legs and hips to the core area when the core muscles contract is equally long, and the muscle length remains unchanged but the tension increases, to buffer this force, and adjust the body posture, so that the center of gravity can stabilize the center of gravity above the support foot.

Immediately afterwards, the ankle, knee and hip joints are used as support points, and relying on the core regulation, the body can still maintain a straight balance during the short-term support stage of one foot, and avoid falling to the left and right sides.

So what are the prerequisites or prerequisites for doing so?

Of course it is... a powerful core capability.

Although the excellent sprinters run at high speed, their one-leg support time is short, but with their strong core balance ability, their body will hardly experience obvious left and right shaking.

This is the first step to reduction.

Why can't others do it?

It is because others do not have such core abilities that Su Shen told them that it is meaningless to let them do it. The people who can do this in the entire Ersha Island have only tried to perfect the quality of the movements every time, and never complained about the hard work and rest.

Of course there are more advanced ones.

It is called dynamic balance adjustment.

I won't mention this for now.

Later, the upper and lower limbs were coordinated with their work and rest, and began to change the power transmission path.

In sprinting, swinging of the upper limbs and pushing the lower limbs are two key movements that cooperate with each other. The core muscles are in between, playing a role in connecting the upper and lower levels.

Everyone knows this.

The question is how to optimize it to a straight line?

Work and rest are done this. From the perspective of the lower limbs, when the leg muscles, quadriceps, hamstrings, calf triceps, and triceps of the calf push the ground with force, the force generated will be transmitted upward along the bones and pass through the hips.

At this time, the hip flexors, extensors, etc. in the core muscle group will participate in the integration and adjustment of the strength, and then continue to pass it upwards to the spine and trunk.

The force generated by the swing of the upper limbs will be transferred through the core area.

Then, when swinging the arm, the forces of the latissimus dorsi, pectoralis major muscle, etc. merge through the core and the force pushing the ground with the lower limbs to form a combined force around the central axis of the body.

Push your body forward in a straight line!

So what are the prerequisites for doing so?

It is also a powerful steel core with extremely high quality.

If the core strength is insufficient, this kind of power transmission will have a "breakpoint".

This leads to dispersed strength and the body posture is prone to imbalance.

There is a situation where there is a sway left and right in an attempt to regain balance.

I did it here without any problems.

As expected by Su Shen.

This is for work and rest.

Not a problem at all.

Secondly, adopt the muscle synergy mode.

Originally, there was a specific co-contraction pattern between the core muscles and the upper and lower limb muscles.

Take the first starting stage as an example.

After hearing the gunshot, the lower limbs quickly stretched out, and the rectus abdomen and oblique abdomen in the core muscles will contract with the deltoid muscles, biceps, etc. of the upper limbs.

Enable the body to quickly get rid of the state of static.

And rush forward along the - straight line.

Acceleration phase.

With the stability of stride frequency and stride width, this synergistic contraction mode continues to work.

As long as the balanced output and reasonable transmission of strength in various parts of the body are maintained, avoid breaking the body's movement state due to excessive or too small force in a certain part.

You can still maintain a better linear motion line!

These specific bodies control their operations.

Each point directly points to the core issue that needs improvement in work and rest.

Let him reduce the left and right deviations during running.

Further maintain the route of linear motion.

As long as you run and sprint, even if you are a sports student, you should know that the more you swing left and right, the greater your actual running distance will be.

The best position is always a straight line.

The shortest distance is always a straight line.

How to make your body more stable in this straight line?

You can get the best short-distance route and distance.

Sprinting.

Especially at the elite level.

The battle is 0.01 seconds.

Work and leisure have made physical changes to this place.

Make his short run more straight.

Reduces the waste of swaying left and right.

It comes naturally.

The speed was increased.

that's why.

Zhang Peimeng clearly started and responded faster.

The four-point and one-line technology is obviously more accurate than last year.

But it is still in the startup and acceleration zone.

There is no reason to get rid of work and rest.

This guy...

affim.

Looking for Su Shen!

This was Zhang Peimeng’s first intuition after he reacted.

Why did he think so?

Because he thought it would be his own.

After encountering these, I got stuck a little.

Wouldn't you use this trick the same way?

Any questions?

Look for Su Shen.

so……

You think.

You gave a small meal.

Just you will ask for a password for GM?

Zhang Peimeng was almost yelling in his heart—

I will too!!!

ps: Big chapter is updated!!!

I asked Su Shen for a plug-in.

Will Zhang Peimeng want it too?
Chapter completed!
