The Su God of the Reopening of the Sports Arena

Chapter 2087: What does super acceleration plus mid-run equal?

After seven steps.

Su Shen has reached the absolute first place.

His speed is unimaginable.

Even the vast majority of the athletes present were quite strong, and there were even masters like Gatlin and Zhao Haohuan...

For their insights.

Even ordinary surprises are not enough to shake them.

That shook them.

It has already been explained...

This is an amazing implication.

Not low anymore.

But this is just the beginning.

Su Shen chose this game as an important one for him, not just to complete a super start show.

What he has to do is challenge his own limits.

Then.

Acceleration zone.

The same cannot be ambiguous.

First of all, you need to have a general understanding of some initial data, and then you will understand why Su Shen chose to make a breakthrough on the plateau.

At the same time, let’s see how much Su Shen has performed on the plateau and how far he is from the theoretical value on the plateau?

The first is the initial speed of the start. In a plateau environment, the initial speed of the start may be faster. This is because the air density in the plateau is lower. According to research, air resistance is roughly proportional to air density. When starting in a plateau environment, the air resistance to the body is reduced by about 10-20% compared to a plain environment.

The second is the current, acceleration phase and speed increase phase.

On the plateau, from the perspective of the acceleration process, due to the increase in the proportion of anaerobic metabolism on the plateau, muscle explosive power can be better exerted during the starting acceleration phase.

Data show that in the first 10 to 30 meters of acceleration after starting in a plateau environment, the athlete's speed may increase 5 to 15% faster than in a plain environment.

therefore.

How to bring out this upper limit, or how to approach this upper limit, has become the most important thing at the moment.

Because physiological data will also change.

For example, heart rate changes. When starting a sprint at a plateau, the body will speed up blood circulation to supply muscles with sufficient energy in order to fight against the low oxygen environment.

The heart rate will rise sharply the moment you start running, and the heart rate may rise about 10-30% faster than when you start running on a plain.

For example, blood lactate accumulation. After starting a race on a plateau, blood lactate accumulation is faster and greater than that on a plain. This is because the proportion of anaerobic metabolism energy supply increases, and the rate of lactate production increases. Generally speaking, at the same time point after starting a race, the blood lactate concentration in a plateau environment may be 1.2-1.5 times higher than that in a plain environment.

With the general information, you can roughly know what the upper limit of what Su Shen can do is.

The first thing to do is -

Swing your arms!

Because.

The air resistance on the plateau is small, so the arm swing amplitude can be appropriately increased to better drive the body forward.

So this second sentence.

The swing arm amplitude can be appropriately increased.

It has strong operability.

What is the basic relationship between arm swing and running?

The arm swinging movement transmits force through the musculoskeletal system, thus assisting the horizontal displacement of the human body. When the arm swings, the upper limb muscles contract to generate force.

Taking swinging your arms backward as an example, this force is transmitted to the torso through the shoulder joint, clavicle and other bone structures.

According to Newton's third law, the action of force is mutual. When the arm swings backward and exerts force on the torso, the torso will generate a forward reaction force. This reaction force will be transmitted to the ground through the pelvis and lower limbs, and interact with the ground. Due to the existence of friction, the ground will give the human body a forward friction force, thereby pushing the human body forward.

Well, if you understand all this, you will know what Su Shen is going to do now.

Why do it on the plateau.

Why not choose the plains?

Because from the momentum theorem, the force generated by the swing arm acts on the human body for a period of time, causing the momentum of the human body to change in the horizontal direction, thereby promoting the horizontal displacement of the human body.

The air on the plateau is thinner and the resistance is lower, making it easier to do this.

It is well known that during running, the human body needs to keep moving in a straight line to achieve efficient displacement. Arm swinging helps coordinate the body's movement direction. If there is no arm swinging action or the arm swing is not coordinated, the body is likely to sway or twist left and right during the forward movement, causing the actual displacement direction of the human body to deviate from the expected direction.

That is, when the arm swing is accurately matched to the leg movement, the body is better able to stay in the sagittal plane... just like the stroke of an oar when rowing a boat.

The swinging arms are like paddles on both sides of the body, and through coordinated movements, the body moves forward in a straight line.

This can reduce the energy wasted in correcting the direction during horizontal displacement.

Now you can swing your arms with greater range while still coordinating the direction of your body's movement.

These magnitudes cannot be achieved on the plains.

That’s not all. Enlarging the swing arm will have other effects and bring even greater changes.

For example, vertical displacement stability.

During a 100-meter sprint, vertical displacement stability helps athletes use energy more efficiently.

When an athlete runs, his energy source is mainly the conversion of chemical energy generated by muscle contraction into mechanical energy.

Vertical displacement stability can ensure that the force generated by the athlete each time he pushes off the ground can be more effectively converted into horizontal propulsion.

If the vertical displacement is unstable, like a running posture with too much "bouncing", it will cause excessive energy loss in the vertical direction.

For example, when an athlete jumps too high, they expend extra energy doing work against gravity.

Stable vertical displacement allows as much energy as possible to be concentrated in the horizontal direction to propel the body forward, which is like installing a more efficient "energy propeller" for the athlete's progress.

According to Newton's third law, when the foot pushes against the ground, the ground exerts a reaction force on the human body.

Steady vertical displacement ensures that the vertical component of this reaction force is not too large, allowing the horizontal component to work more effectively and allowing the athlete to move forward at a faster speed.

Then now is the time to do it.

Su Shen swung his arms vigorously.

At this time, the arm swinging force that had been somewhat restrained finally found a breakthrough!

On a normal day, you want to fully open the swing arm function, which is basically unrealistic because you also have to consider the overall balance.

Under the training conditions on the Great Plains, no matter how strong your upper body strength is, you will be forced to seal off part of it.

Sacrifice for the whole.

But in the plateau area.

The situation is different.

In plateau areas, people's arm swing amplitude and frequency can become larger.

Because - the air resistance on the plateau is small, the swing arm amplitude can be appropriately increased!

You can better drive your body forward!

Su Shen's upper body strength.

Through deliberate scientific development since childhood, he has already become one of the top athletes in active service.

Why do I say that? If other athletes develop upper body strength, there must be better talents and better people who can grow than Suarez.

but.

In most people's minds, sprinting is mainly a sport for the lower limbs.

Even in Europe and the United States, more emphasis is placed on muscle mass.

It is better to focus more on the development of the lower body.

That is to say, when people don’t pay much attention to the development of the upper body.

Su Shen carried out the most scientific, standardized and maximum upper body development by himself.

If he is not the current sprinter, who has the best upper body strength?

No, that's all looking down on Su Shen's comprehensive scientific training over the years.

That is to look down on science.

With such an answer, you will understand why it was said that Su Shen was wronged in the previous training.

Because it is in a plain area.

There is no way to open up the upper limb power of these seals any further.

We can only converge for the sake of integrity.

What now?

Finally he found the opportunity.

Finally I can swing my arms freely!!!

Bang bang bang bang bang.

Su Shen walks very fast!

From the perspective of energy transfer, stable vertical displacement can ensure good transfer of power from the legs to other parts of the body!

In the process of sprinting, the power is generated from the lower limbs and transmitted through a series of links such as the hip, waist, upper limbs, etc. Vertical displacement stability can enable athletes to form a stable force transmission chain at the moment of pushing off the ground.

That now.

Su Shen is using the most common and basic arm swing to transfer this energy chain...

To expand thoroughly.

activation.

Bigger and bolder!

You should know that in the starting stage, athletes need to use their powerful leg strength to explosively push off the starting blocks.

If the vertical displacement is unstable, part of this force will be lost in the process of upward dispersion and cannot be effectively transmitted to the front of the body to propel the athlete to accelerate.

So now...

Su Shen simply swings his arms to more effectively transfer the energy, which would inevitably be dissipated on the plains, into his body.

Let him be the driving force for progress.

Further upgrade.

Reach new limits.

Bang bang bang bang bang.

When vertical displacement is stable, the force generated by the legs can be like following a stable track.

It is smoothly transmitted to the upper limbs through the pelvis, spine and other parts.

Make the whole body form a coordinated forward movement.

Thereby achieving better acceleration effect.

This guy.

What's going on with this guy?

how……

How can it accelerate so fast?

It used to be fast.

just now.

It’s incredibly fast!

Bang bang bang bang bang.

Half a body length.

Half a body length.

Half a body length.

Crazy pull!!!

Is that enough?

not enough!

Twenty meters later, Su Shen's performance has not stopped yet!

In the 100-meter sprint, body balance is critical. Vertical displacement stability helps maintain the body's balance during high-speed movement.

When running, the body's center of gravity will constantly change with the movement of the footsteps. If the vertical displacement is unstable and the vertical change of the body's center of gravity is too large, it will easily cause the body to lose balance.

Once the balance is lost, the athlete needs to spend extra time and energy to adjust the posture, which will greatly affect the running speed.

When athletes are running, they are actually always in a process of resetting, adjusting and re-preparing.

It’s just that the size of the sacral sacs in elite athletes is relatively small and cannot be seen with the naked eye.

But if you slow down and watch, you can still see the clues.

And Su Shen's core is already strong enough, so how can it become stronger? More stable?

That is to take advantage of the vertical displacement stability characteristic.

From a stability perspective, stable vertical displacement can provide a stable support base for the body.

Sprinters' legs need a stable vertical state to ensure the accuracy of each movement during the frequent pushing off and landing process.

How to be more precise? Humans are mortals, and it is impossible for them to be as accurate as machines every time, so stability is needed to get closer to this value.

Su Shen now.

This is it.

In addition, he runs so fast that if the vertical displacement is unstable, his legs will easily experience excessive inversion or eversion when landing, increasing the risk of injury and affecting the effect of the next push off.

Now, all of them are improved in vertical displacement stability by his powerful arm swing.

Get closer to the theoretically accurate value.

Bang bang bang bang bang.

Twenty-five meters!

Su Shen's vertical displacement stability now allows his legs to touch the ground at a suitable angle and force when landing.

That will make the entire body's support system more stable!

Provide more solid protection for subsequent actions!

Bang bang bang bang bang.

Because of the above factors, the body is now more stable. The body is a sophisticated instrument, so...

The advantage of stable vertical displacement, which enables muscles to be more coordinated during contraction and relaxation, also begins to emerge!

We all know that sprinting involves the coordinated work of many muscle groups, including the quadriceps, hamstrings, gluteus maximus, and core muscles in the legs.

When vertical displacement is stable, these muscles can fire in a fixed pattern.

Otherwise many problems will arise.

The more stable.

The fewer problems.

Bang bang bang bang bang.

Thirty meters!

During this push-off phase, Su Shen's quadriceps are mainly responsible for extending the knee joint!

The glutes and hamstrings work together to extend the hip joint!

Steady vertical displacement allows these muscles to contract at the right intensity at the right time!

Further avoid strength offset or overcompensation between muscles!

How could it not be faster then?

It’s about to take off!

It can be said that this is Su Shen’s acceleration zone!

It has never been so fast.

The people behind were stunned.

This guy……

What happened to this guy?

Not only does he start quickly, he can be considered an explosive starter. Anyway, he is the best starter in the world.

Blue Star is invincible.

But is the acceleration zone also like this now?

What's going on?

Gatling is numb!

Ryota Yamagata and Masafumi Eriguchi admired him even more!

Zhao Haohuan was also a little stunned...

He knew what Su Shen was going to do.

but.

Even if I'm mentally prepared, this is still...

Isn't it too fast?

Su Shen’s acceleration zone?

Is there anyone that fierce?

like.

This has never happened before, right?

It’s just...

It almost gives him a bit of Usain Bolt feeling!

Yes, that's Bolt!

Not to mention this year's evolved version of Bolt, it can at least be equivalent to the previous Bolt, infinitely close!

Compared with these acceleration bosses, Su Shen's acceleration zone can only be said to be not lagging behind, but it can't gain any advantage.

what about now?

Zhao Haohuan didn’t dare to say it!

Haven't stopped yet.

Su Shen gradually began to raise his head.

Ran on the way in!

carry on.

In good shape.

do not stop.

Keep the feeling going!

If we were to play like this in a plain area, the vertical displacement would have become unstable long ago.

Once this area is unstable, the order and intensity of muscle contraction will be disrupted.

For example, there may be a situation where the quadriceps are over-contracted and the gluteus maximus is not fully engaged.

This reduces the overall efficiency of your muscles.

Especially for Su Shen, who has the gluteus maximus talent, it is simply...

Huge waste.

it's good now!

Through the vigorous arm swinging on the plateau, I was finally able to sustain the vertical displacement stability that I couldn't achieve on the plains!

This is equivalent to liberating your gluteus maximus talent in disguise!

This is the chain reaction of breakthrough.

The body is a whole.

It is never divided!

If this place becomes stronger, the rest of the places will probably be handled well and become stronger as well.

Bang bang bang bang bang.

Thirty-five meters.

Forty meters.

Su Shen ran exceptionally smoothly!

This is because……

After the gluteus maximus breaks through the mobilization limit, there is another problem that is also improved.

That is, from the perspective of muscle fatigue, vertical displacement stability helps reduce the occurrence of muscle fatigue.

That's right.

That is, muscle fatigue management will also change accordingly.

Otherwise, even if you force yourself to move so much on the plains, you will start to get tired earlier because your muscles consume excessive energy.

That way.

It's like drinking poison to quench thirst.

It became like picking up sesame seeds and losing watermelons.

But now...

No.

Don't worry about it!

You can move freely!

Come.

let me see.

I have spent so many years honing my own absolutely scientific body.

in the end.

There is still so much potential to be tapped.

It can explode.

Come.

Let me see for myself.

How much energy do I have left?

Bang bang bang bang bang.

Su Shen is still attacking violently.

When vertical displacement is unstable, muscles need to constantly adjust their contraction state to adapt to irregular changes in the body's center of gravity.

But now?

Vertical displacement is more stable.

So... doesn't it mean that... there is no need to adjust the contraction state so much to adapt to the irregular changes in the body's center of gravity?

of course!

In the past, this extra adjustment would cause the muscles to consume more energy in a short period of time, accelerating the process of muscle fatigue.

Nowadays.

No.

How to describe it.

Su Shen showed that he had a lot of internal strength in the past, but due to environmental reasons, he was unable to fully utilize it.

just now.

Standing on the plateau.

He finally can.

Have a great outburst!!!

Forty-five meters.

Steady vertical displacement allows the muscles to work in a relatively stable state.

Then the energy consumption is more regular.

Being more regular will allow the body to maintain higher contraction force and speed for a longer period of time!

Delay the onset of muscle fatigue!

Make the athlete run throughout the entire 100-meter run.

Longer lasting performance!

This feeling.

It's amazing.

Don't talk about others.

Su Shen himself was so excited about running!

Such a strong run.

When he was in the plains, he had no way of feeling it at all.

Now it's like one of the seals on my body has been lifted.

After so many years of scientific training, the basic potential laid down is disappearing along with the seal.

More and more fulfilled!

Look, the speed zone ahead is coming.

The only thing in Su Shen’s mind right now is...excitement.

You can run like this even when running on the way.

What about the extreme speed zone?

Can the extreme speed zone be even more violent?

Can it continue?

Can...

Burst out with even greater speed.

Su Shen.

I am waiting to see.

Bang bang bang bang bang.

The sound of spikes breaking through the air continued to explode on the ground.

Fifty meters.

Su Shen watched himself go by.

The speed of the body is liberated.

It's like having muscle memory.

Then they were liberated together.

Bang!

Rapid explosion!

Keep going...high energy!!!
