After seven steps.
Su Shen has reached the absolute first one.
His speed is unimaginable.
Even most of the athletes on the scene have not been low, and there are even experts like Gatlin and Zhao Haohuan...
What they know.
The average shock is not enough to shake them.
Since it has shaken them.
It already explains...
This amazing meaning.
Not low anymore.
But this has just begun.
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 to challenge his own limits.
So.
Acceleration zone.
Also not vague.
First of all, you need to understand some initial data roughly, and you will understand why Su Shen chose to make a breakthrough on the plateau.
At the same time, see how much Su Shen played on the plateau and how much is the difference from the theoretical value on the plateau?
The first is the starting speed. In a plateau environment, the starting speed may be faster. This is because the plateau air density is low. According to research, air resistance is roughly proportional to the air density. Starting in a plateau environment, the air resistance the body receives is reduced by about 10-20% compared to the plain environment.
The second is the current stage of acceleration stage speed improvement.
On the plateau, from 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 stage.
Data show that during the acceleration of the first 10-30 meters after starting in a plateau environment, the athlete's speed may increase by 5-15% faster than the plain environment.
therefore.
How to exert 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 plateau short-term, the body will speed up blood circulation to provide sufficient energy to the muscles in order to combat the hypoxic environment.
The heart rate will rise sharply at the beginning of the start, and the heart rate may rise by about 10-30% faster than when starting from the plains.
For example, blood lactic acid accumulation, the accumulation of blood lactic acid after starting the plateau is faster and more than that of the plain. Because the proportion of anaerobic metabolism energy supply increases, the rate of lactic acid production is faster. Generally speaking, at the same time point after starting, the blood lactic acid concentration in the plateau environment may be 1.2-1.5 times higher than that in the plain environment.
With rough information, you can roughly know how much operational limit Su Shen wants to do.
The first thing to do is-
Swing the arm!
Because.
The air resistance of the plateau is small, and the swing arm can be appropriately increased to better drive the body forward.
Then this second sentence.
The amplitude of the swing arm can be increased appropriately.
It has strong operability.
What is the basic relationship between arm swing and running?
It is the movement of the arm swing to transmit force through the musculoskeletal system, thereby generating a boost to the horizontal displacement of the human body. When the arm swings, the muscles of the upper limbs contract and generate strength.
Taking the swinging arm swing backward as an example, this force is transmitted to the trunk through bone structures such as shoulder joints and clavicles.
According to Newton's third law, the effects of forces are mutual. When the arm swings backward to apply force to the trunk, the trunk will produce a forward reaction force. This reaction force will be transmitted to the ground through the pelvis and lower limbs, interacting 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 to move forward.
Then, if you understand these things, you will know what Su Shen is going to do now.
Why do it on the plateau?
Why not choose on the plain?
Because from the momentum theorem, the force generated by the swing arm acts on the human body over 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.
Then the air on the plateau is thin and the resistance is lower, making it easier to do this.
It is known that during running, the human body needs to keep moving forward in a straight line to achieve displacement efficiently. The swing arm helps coordinate the direction of the body's movement. If there is no swing arm movement or the swing arm is not coordinated, the body will easily shake left and right or twist during the advancement, causing the actual displacement direction of the human body to deviate from the expected direction.
That is to say, when the arm swinging movement can accurately match the leg movement, the body can better maintain movement on the sagittal plane... just like the paddle paddle when rowing.
The swinging arms are like oars on both sides of the body, and through coordinated movements, the body moves in a straight line.
This can reduce the energy waste during horizontal displacement in the corrective direction.
Then, now the arm swing can be more large and can maintain the coordinated direction of the body's movement.
These amplitudes cannot be achieved in plains.
This is not the end. Increased arm swing and other effects can also bring greater changes.
For example, vertical displacement is stable.
During the 100-meter sprint, stable vertical displacement helps athletes use energy more efficiently.
When an athlete runs, his energy source is mainly the chemical energy generated by muscle contraction converted into mechanical energy.
The stable vertical displacement can ensure that the force generated by the athlete's pushing ground can be more effectively converted into horizontal propulsion force.
If the vertical displacement is unstable, it is like a running posture with too much "jumping", which will cause excessive energy loss in the vertical direction.
For example, when an athlete jumps up too much, it consumes extra energy to overcome gravity and do work.
The stable vertical displacement allows energy to concentrate as much energy as possible to push the body forward, just like installing a more efficient "energy propeller" for the athlete's progress.
According to Newton's third law, when the foot pushes the ground, the ground produces a reaction force against the human body.
The stable vertical displacement can ensure that the vertical component of this reaction force will not be too large, so that the horizontal component can function more effectively and allow the athlete to move forward at a faster speed.
Then now is the time to do it.
Su Shen waved his arms hard.
At this time, the arm swinging power that was previously bound to be somewhat bound, finally found a breakthrough!
This chapter is not finished yet, please click on the next page to continue reading the exciting content later! On weekdays, you want to fully turn on the arm swing function, which is basically unrealistic because you also have to consider the overall balance.
Under the training conditions of the Great Plains, even if your upper limbs are strong, you can only be forced to seal a part of them.
Sacrifice for the whole.
But in the plateau area.
The situation is different.
In plateau areas, people's arm swing amplitude and frequency of arm swing can become larger.
Because the plateau air resistance is small, the swing arm amplitude can be appropriately increased!
You can better drive your body forward!
Su Shen’s upper limbs.
Through deliberate scientific development since childhood, he has long been the top one among active athletes.
Why do you say so? If the rest of the athletes develop upper limb strength, there will definitely be people with better talent for listing than those developed by Su Shen.
But.
In the minds of most people, sprinting is mainly about lower limbs.
Even in Europe and the United States, pay more attention to muscle mass.
Or focus more on the lower body development.
That is to say, when people do not pay much attention to upper body development.
Su Shen carried out the most scientific, standardized and maximum upper body development with a person.
Then he is not an active sprinter. Who is the one with the best upper limb strength?
No, that's all because of all the comprehensive and scientific training of Su Shen for so many years.
That is to look down on science.
With such an answer, you will know why Su Shen was wronged in the past training.
Because in plains.
There is no way to open up the upper limbs of these seals more.
It can only be converged for the sake of integrity.
What about now?
Finally he found a chance.
Finally, I can wave my arms freely!!!
Bang bang bang bang bang bang bang.
Su Shen walked vigorously under his feet!
From the perspective of energy transfer, stable vertical displacement can ensure good transmission of strength from the legs to other parts of the body!
During the sprinting process, strength is generated from the lower limbs and is transmitted through a series of links such as the hips, waist, and upper limbs. The stability of vertical displacement can enable athletes to form a stable force transmission chain at the moment of pushing the ground.
Then now.
Su Shen is passing this energy transmission chain through the most ordinary and seemingly basic arm swing...
To be completely expanded.
activation.
Increase and bold!
You should know that at the starting stage, athletes need to burst out of the starting device through powerful leg strength.
If the vertical displacement is unstable, this force will lose part of it during the upward dispersion and cannot be effectively transmitted to the front of the body to promote the athlete to accelerate.
Then now...
Through a simple swing of his arms, Su Shen made the energy that would inevitably be dissipated in the plains and was more effectively transmitted to his body.
Let his advancement drive.
Further upgrade.
Reach new limits.
Bang bang bang bang bang bang bang.
When the vertical displacement is stable, the force generated by the legs can be like along a solid track.
It is smoothly transmitted to the upper limbs through the pelvis, spine and other parts.
Make the whole body form a coordinated forward motion.
This will achieve better acceleration effect.
This guy.
What's going on with this guy?
how……
How can you speed up so fast?
It was soon before.
Now.
It's even more amazingly fast!
Bang bang bang bang bang bang bang.
Half a seat.
Half a seat.
Half a seat.
Crazy to pull away!!!
That's enough?
Not enough!
Twenty meters later, Su Shen's performance had not stopped yet!
In a 100-meter sprint, body balance is very critical. The stability of vertical displacement helps maintain the body's balance in high-speed movement.
When running, the center of gravity of the body will constantly change with the movement of the footsteps. If the vertical displacement is unstable and the vertical change of the center of gravity of the body is too large, it is easy to cause the body to lose balance.
Once the balance is lost, athletes need to spend extra time and energy to adjust their posture, which can greatly affect running speed.
During the athlete's running, there has always been a process of resetting, adjusting and re-adjustment.
It’s just that elite athletes are relatively small and cannot be seen with the naked eye.
But if you look slower, you can still see the clues.
And Su Shen’s core has become stronger to the top, so how can it become stronger? More stable?
That is to take advantage of this vertical displacement stability characteristic.
From a stability perspective, stable vertical displacement can provide a stable support base for the body.
During the frequent push and landing of the sprinter's legs, a stable vertical state is needed to ensure the accuracy of each movement.
How to be more accurate?
Humans are all mortals with naked eyes, and it is impossible to be like machines every time, so they need stability and closer to this value.
Su Shen is now.
That's it.
In addition, if he runs so fast, if the vertical displacement is unstable, his legs will easily experience excessive inversion or outturn when they land, which will increase the risk of injury and will also affect the effect of the next stepping.
Now, all of them are swinging their arms with strong force to improve the stability of vertical displacement.
Let yourself get closer to that theoretical accurate value.
Bang bang bang bang bang bang bang.
Twenty-five meters!
Su Shen now has a stable vertical displacement to allow the legs to touch the ground at a suitable angle and force when landing.
This will make the support system of the entire body more stable!
Provide more solid guarantees for subsequent actions!
Bang bang bang bang bang bang bang.
Because of the above elements, the body is now more stable, so the body is a precise instrument. In this way...
The advantages of stable vertical displacement that can make the muscles more coordinated during contraction and diastolic also begin to show!
We all know that sprinting involves the coordinated work of many muscle groups, including the quadriceps, hamstrings, gluteus maximus, and core muscle groups in the legs.
When the vertical displacement is stable, these muscles can exert force in a fixed pattern.
Otherwise, many problems will arise.
The more stable it is.
The fewer the problems.
Bang bang bang bang bang bang bang.
Thirty meters!
During this stage of striking the ground, Su Shen’s quadriceps are mainly responsible for stretching the knee joint!
The gluteus maximus and hamstrings work together to stretch the hip joint!
This chapter is not over, please click on the next page to continue reading! The stable vertical displacement allows these muscles to contract at the right strength at the right time!
Further avoid the situation of force offset or excessive compensation between muscles!
That way, how can it not be faster?
It's all about to take off!
It can be said that Su Shen’s acceleration zone!
It has never been so fast.
It was stunned for everyone behind.
This guy...
What's wrong with this guy?
Forget it if it starts quickly, it can be considered a explosive type. Anyway, he is also the number one startup in the world.
Blue Star is invincible.
But the acceleration zone is the same?
What's going on?
Gatlin is so irritating!
Liangtai and Jianglikou Kuangshi in Shan County admire him even more!
Zhao Haohuan was also a little stunned...
He knew what Su Shen was going to do.
But.
Even if you are mentally prepared, this will...
Too fast, right?
Su Shen’s acceleration zone?
Is there anything so fierce?
like.
Haven't had it before?
It's simply...
It gave him a bit of Usain Bolt!
Yes, it's Bolt!
Not to mention this year's evolutionary version of Bolt, at least it can be equivalent to the previous Bolt, and it is infinitely close!
Compared with these people’s acceleration zone, Su Shen’s acceleration zone can only be said to be not dragging the ball, but he can’t take any advantage.
What about now?
Zhao Haohuan dare not say anything!
Haven't stopped yet.
Su Shen gradually began to look up.
Running on the way!
continue.
Good condition.
Don't stop.
Let the feeling...continue!
If I were to play like this, if it were in a plain area, the vertical displacement would have been unstable long ago.
Once it is unstable here, the order and intensity of muscle contraction will be disrupted.
For example, the quadriceps femoris may contract excessively and the gluteus maximus does not function fully.
This will reduce the overall work efficiency of the muscles.
Especially for Su Shen, a person with the talent attribute of gluteus maximus, it is simply...
Huge waste.
Now it's OK!
Through the powerful arm swing of the plateau, I finally supported the vertical displacement stability that I could not achieve in the plains!
This is equivalent to liberating one's gluteal maximus talent in disguise!
This is the chain's breakthrough reaction.
The body is a whole.
Never split!
If this place becomes stronger, the rest of the place may be handled well and can also become stronger as well.
Bang bang bang bang bang bang bang.
Thirty-five meters.
Forty meters.
Su Shen ran extremely 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, stable vertical displacement helps to reduce the occurrence of muscle fatigue.
That's right.
Even muscle fatigue management will change as well.
Otherwise, even if you force so much on the plain, you will start to get tired earlier because your muscles consume excessive energy.
That way.
It's like drinking poison to quench thirst.
It turned into picking up sesame seeds and losing watermelon.
But now...
No.
No need to worry about it!
Can be mobilized happily!
Come.
let me see.
I have polished my absolute scientific body for so many years.
in the end.
How much potential can be tapped?
It can explode.
Come.
Let me see it myself.
How much energy do I have?
Bang bang bang bang bang bang bang.
Su Shen is still violently attacking.
When the vertical displacement is unstable, the muscles need to constantly adjust the contraction state to adapt to irregular changes in the body's center of gravity.
But what about now?
The vertical displacement is more stable.
So it's not... it doesn't take so much adjustment and contraction to adapt to irregular changes in the body's center of gravity?
Of course yes!
In the past, this extra adjustment would cause the muscles to consume more energy in a short period of time and accelerate the progress of muscle fatigue.
today.
No.
How to describe it?
Su Shen showed that he had only had internal strength in the past, but he was unable to exert all his strength due to environmental reasons.
Now.
Standing on the plateau.
He can finally.
Have a happy explosion!!!
Forty-five meters.
Stable vertical displacement allows muscles to work in a relatively stable state.
Then the energy consumption is more regular.
More regularity can enable the body to maintain a higher contraction force and contraction speed for a longer period of time!
Delay the occurrence of muscle fatigue!
Make athletes run during the entire 100-meter journey.
More lasting performance!
This feeling.
It's so awesome.
Don't talk about others.
Su Shen himself is about to run away!
Running on such a strong way.
When he was in the plains, he had no way of feeling it.
Now it's like the body's seal has been removed.
After so many years of scientific training, the potential for laying a good foundation is disappearing with the seal.
Better deliver!
I watched the speed zone ahead coming.
Su Shen's mind is only...excited.
You can run like this on the way.
So what about the speed zone?
Can the speed zone be more violent?
Can it last?
Can it be...
Breaking out at a stronger speed.
Su Shen.
I will wait and see.
Bang bang bang bang bang bang bang.
The sound of nailed shoes breaking through the air constantly exploded on the ground.
Fifty meters.
Su Shen looked at himself passing by.
The speed of the body is liberated.
It's like having muscle memory.
Let's go liberate with one another.
Bang!
Extremely exploded!
Chapter completed!
