The Su God of the Reopening of the Sports Arena

Chapter 2244: Suppressing Everyone! Including the Olympic Champion and the World Championship Champion
Lausanne Stadium.

Two hours passed quickly and the audience returned to their seats one after another.

The competition is about to begin, which is the 100-meter final.

Women's 100 meters.

and the men's 100m.

It all starts here.

"Hello, audience friends, today we are going to bring you a group of strong dialogues. I know everyone is anxious, but don't be anxious yet,"

“We have already achieved a lot of good results in the Lausanne Diamond League. Now we have to see if we can get another good result in the final 100 meters.”

Yang Jian explained professionally, "Since there is no preliminaries for the women's 200m, we will go straight to the finals."

"There are nine contestants in total."

"They are Jeter, Okabare, Muna Lee, Stuart, Campbell Brown, Chen Juan, Wei Yongli, Sharonda Solomon, and Yvette Lalois-Collio."

"There are many talented people, but fortunately, this is the first year after the Olympics, and many people are not in good shape and no longer have the enthusiasm of last year."

"Under such circumstances, our country's players still have a chance to compete."

This Chinese contestant actually refers to Chen Juan.

Because the rest of the contestants have no chance of competing at all.

Chen Juan thought so too. She wanted to see if she could still achieve a good result after the altitude decreased to the height of the Little Mexico Stadium.

Or how good a result you can achieve.

This can give me a certain psychological prediction of my performance in Moscow.

The rest.

Most likely you think so.

There is something very true about what Yang Jian said.

Even among this group of athletes, some are very famous.

There are many people with big names.

There are many people who have more honors than Chen Juan.

But this year.

It just refers to this year.

It’s not necessarily true, he is just that much stronger than her.

This is what Su Shen said about taking advantage of the decline of one side this year.

Maybe everyone can give it a try.

After all, grades don’t necessarily have to be particularly outstanding.

But honor does exist in a real way.

Sometimes you do the right thing at the right time.

It’s just easier to take away the honor.

You have to admit that this is how things are in this world.

Most people cannot take the path of a peerless genius.

Of course, a peerless genius can always take the most honorable path and disdain to take these paths.

Conquering the strongest opponents is an act of identification with their own path.

But few ordinary athletes would think this way.

At least based on reality.

I wouldn’t think that way.

The reason is simple.

Most people are not jazz geniuses and do not have the opportunity to do things that challenge human limits.

For them, being an athlete is just an identity and a profession.

So if you can get a higher honor.

Even if you take some shortcuts.

The situation is exploited.

As long as it is allowed by the rules.

There are definitely a lot of people willing to try.

Otherwise, where do you think so many people who take drugs come from?

Don’t they know that taking medicine is shameful?

Therefore, if there is a way to get honor without taking shortcuts, no one can refuse it.

Few ordinary people have the mentality of a gifted child of destiny.

"set."

Bang——————————

Jeter used a conventional crouching starting posture, with his feet firmly on the starting blocks, his body slightly leaning forward, his center of gravity lowered, and his eyes fixed on the track ahead.

The front pedal angle is 45°, the rear pedal angle is 60°, and the angle between the torso and the ground is 40°, forming a stable triangular support structure.

0.1 second before the gun goes off, activate the quadriceps first, then activate the gluteus maximus synchronously, forming a "knee extension-hip extension" chain force.

The characteristic of her starting technique is her quick reaction speed. The moment she hears the gunshot, she can react quickly and use her powerful leg explosive power to quickly push off the starting blocks.

From a biomechanical point of view, this starting method uses the support reaction force provided by the starting blocks, and through the rapid contraction of the leg muscles, pushes the body forward and upward, so that the body can obtain a large initial velocity in a short period of time. In addition, her starting reaction time is relatively stable, which gives her a certain advantage in the starting stage.

However, doing so will over-rely on the quadriceps and cause the patellar tendon to be loaded up to 8 times the body weight.

It is easy to cause muscle coordination disorder after starting.

She ran so hard last year.

You have to take a rest this year, otherwise there will be no future.

In fact, having a good rest does not necessarily mean there will be a future.

She was born in 79, which means she is a post-70s generation. Now is not the early 21st century, and those born in the 80s are considered veterans, let alone a member born in the 70s.

Her best result this year is actually around 10.93.

This result is obvious, and we no longer have the ability to compete for medals on the world's top level.

But she is so old, it is right for her to take a rest after a year of hard work like in the Olympics.

For a famous athlete like her, the focus is of course the Olympics, if she can only save one.

Okabare's starting posture is also standard. She will adjust her breathing before starting to put her body and mind in the best condition.

When the gun sounded, the starting movement was smooth and powerful.

The leg extension movement is quick and coordinated.

Her advantage in starting technique lies in her control of rhythm. At the moment of starting, she can control the rhythm of her movements well to avoid deformation of movements due to excessive haste, thus ensuring the efficiency of the start.

This precise control of rhythm enables her to quickly get out of the stationary state at the start and enter the acceleration phase.

Use the "4-2 breathing method" to put the diaphragm in the best mechanical position, and increase core stiffness by 15% when the gun goes off.

The stretching strategy has also changed compared to last year.

This is also one of the main reasons for the significant breakthrough in evolution this year.

Adopting "step-by-step force"——

Focus on extending your knee for the first 0.1 second.

The knee joint angle changes from 90° to 150°.

Add hip extension after 0.1 second.

The hip joint angle changes from 110° to 170°.

Avoid force vector dispersion.

This year we can reach the world's top level in one go.

Okabare has also improved a lot in terms of technique.

No wonder I’m so confident this year.

Muna Lee's starting technique focuses on utilizing the elastic potential energy of the legs.

When she starts running, her leg muscles are stretched to a certain extent in advance, like a compressed spring, and when the gun goes off, her leg muscles contract quickly.

The stored elastic potential energy is released, pushing the body forward.

This starting method can generate greater power in a short period of time, allowing her to obtain a faster initial speed at the start. At the same time, her starting movement is larger, which also helps her gain greater forward momentum at the start.

The tendon rebound cycle and the Achilles tendon energy storage-release cycle are 0.18 seconds, which match the step frequency to form "elastic resonance".

The maximum flexion of the swing leg knee joint is 130°, which is even 10° greater than Jeter's.

Reduce the moment of inertia by 0.05kg·m.

The angular velocity of leg swing increases by 10%.

It is this "elastic resonance" running method that can easily cause the elastic system load to reach its limit, such as Achilles tendon tension of 420N.

If the output continues, tendinopathy may occur.

Although Li was not born in the 80s, he was born in 81, and was already over 30 years old at that time.

At the age of 32, it is understandable that there is a decline in performance.

She is no longer the same person she was back then.

at least.

This year, she no longer has the ability to reach her peak.

This running method brought her a lot of benefits when she was at her peak.

It's a pity to look at it now.

We have already started to enter the opposite side of benefits and started to pay for our own negative effects.

This year her time has actually fallen below 11 seconds.

Even though I was close to full marks, I could only run to 11.

Look at those days, there were people who could run 10 seconds.

It's a pity that times have changed.

We no longer have this capability.

A special elastic resonance running method.

Now there are only negative effects.

It's difficult to give her positive feedback.

She never opened an 11-second mark again in her career.

It started to go downhill completely.

Stewart's starting technique emphasizes the rapid transfer of the body's center of gravity.

When she starts running, she will quickly move her body weight forward, so that her body is in a state of forward acceleration at the moment of starting. In this way, she can get rid of the static inertia at the start more quickly and enter the acceleration phase.

Moreover, her starting movement is very coordinated, with her arms and legs moving in perfect harmony, effectively propelling her body forward.

This technique of shifting center of gravity requires athletes to have a good sense of balance and body control.

Stuart is an athlete with long legs.

If you have the advantage of long legs, you also have to bear the disadvantages of long legs.

Over 1 meters tall.

Her starting point is -

By increasing the forward swing of the hip joint.

Up to 45°.

At the same time, it compensates for the leg swing delay caused by leg length.

Maintain the support period/swing period ratio at 1:1.2.

The arm swing range is up to 50°, and the normal range is 35°.

By increasing the angular momentum of the upper limbs, the inertia moment of the lower limbs is balanced.

Technically, this is done through the "ankle flexion running method".

This is called 15° ankle dorsiflexion.

Reduce the braking impulse when the foot touches the ground by 18%.

To start acceleration as quickly as possible.

She is 29 years old this year, and if she is a female athlete for a long time, she is still at the end of her peak.

It is still possible to break 11 seconds this year, but not many people can do so.

Her way of running with ankle flexion.

She once had a strong presence in women's sprinting, but as she got older, her physical functions gradually declined, and it was difficult for her to perfectly maintain the physical energy required for this running style.

Although she had her own brilliance.

Athletes who have reached this level basically have their own special mechanisms.

Now let’s see if you can make new changes after using this mechanism to the fullest.

Or introduce new mechanisms to extend the life of your special mechanisms.

Next to her is her fellow villager Brown.

Stewart could barely drive for eleven seconds.

Then there is Brown, who was once at the peak of his career.

She was able to fight with Chen Juan last year.

This year it’s like a different person.

Campbell Brown has her own unique starting technique. She will raise her head slightly when starting, which allows her to better observe the track conditions in front of her at the moment of starting, and also helps her adjust her breathing.

Although her starting reaction speed is not the fastest, her starting movement is very steady and she is able to maintain her body balance during the starting phase.

When she started running, the force of her leg extension was even, which could continuously provide forward momentum for her body.

This steady starting method prevents her from making major mistakes at the start, laying a good foundation for the subsequent acceleration stage.

but.

This run is closer to 200 meters.

The peak torque of knee flexion and extension is controlled within 200 N·m, which is 25% lower than that of Jettel, and the impact load is reduced by extending the extension time.

Visual positioning is performed every 10 meters.

Marking the specific pattern of the track.

Maintain acceleration confidence through spatial referencing.

Reduce subjective fatigue.

This is also one of Brown's secrets.

pity.

She has been resting all this year.

We competed too hard last year during the Olympic Games.

Give yourself some rest this year.

Although she is 31 years old this year, her peak period has not yet ended and will continue until 2017.

It was not until 2018 that the market started to fall sharply.

It's still early.

The biggest problem is——

If she doesn't give herself some time to recover, her body won't be as strong as it was when she was young.

Selective giving up is a necessary thing this year.

As an experienced veteran.

at this point.

She is sober.

This is also the reason why her career peaked for so long.

People who don't know how to manage their bodies are destined to decline drastically after their youth is over.

It's difficult to continue.

at this point.

Also includes Bolt from the previous life.

Wei Yongli's starting technique this season focuses on the use of starting blocks.

I saw that before starting, she would carefully adjust the angle and position of the starting blocks to adapt to her own starting habits.

When starting, she will make full use of the elasticity of the starting blocks, quickly stretch her legs, and use the rebound force of the starting blocks to make her body rush forward quickly.

At present, the key to her starting technique lies in the precise control of the elasticity of the starting block. Through reasonable pushing force and timing, she can maximize the role of the starting block and obtain a greater initial velocity.

A gentleman is good at making use of tools.

That’s been true in her season.

Fully reflected.

Because this can preferentially activate type I fast-twitch muscle fibers, which have a contraction speed of 8.3 m/s, 15% faster than type II fibers.

The inclination angle of the starting block is increased from the conventional 12° to 15°, the pedaling distance is extended by 3cm, and the energy rebound efficiency is increased by 5% with a 9mm thick carbon fiber pedal.

In view of the anatomical characteristics of the gastrocnemius muscle insertion point being low, 1.8 cm lower than the average, a "forefoot-back" stance is adopted so that the extension force line passes through the center of the Achilles tendon.

at this point.

It’s much stronger than last year.

Use of starting blocks.

It is a very important thing in modern times.

This is the first thing Randy wanted to talk about after coming to China.

Su Shen is extremely precise when it comes to the starting blocks.

That's what Randy asked for.

Wei Yongli is now beginning to inherit this.

In the past, coaches just made random eyeball assessments. In Randy’s words, the previous domestic training system simply did not bring into play the effectiveness of the new sprint runners created by modern technology.

It's a complete waste.

It is also a disrespect for the combination of modern technology and sports economy.

Obviously it would be faster if they were combined.

why not?

Having said that, the overall domestic environment is that the utilization rate of something as simple as a starting block is not high, as if no one knows how to integrate technology with this modern starting block.

There was no new clue until Randy came over.

After Wei Yongli combined here.

There is clearly a boost in startup.

And not much physical technical processing was done.

Sharonda Solomon's starting technique focuses on the agility of the starting action. When she hears the gunshot, her body can react quickly, and her starting action is clean and neat, without any unnecessary movements.

Her starting technical advantage lies in her quick reaction, which enables her to make the starting movement in the shortest time, thus gaining the upper hand at the start.

This agile starting reaction requires athletes to have good nerve reflex ability and fast muscle reaction speed.

Reflex arc optimization.

The latency of the spinal stretch reflex is only 25ms.

8ms faster than average, making muscle response 0.01 seconds faster.

Using "generalized activation"——

0.3 seconds before the gun is fired, 63% of the body's muscle fibers are activated, and normally about 45% are activated, forming a "whole-body catapult" effect.

The energy consumption of excess movements at the start is only 12J, 35% less than Jeter, thanks to the precise compilation of the movement program by the cerebellum.

but.

She's been in pretty average shape lately.

The transition from winter training was not smooth.

Not only was the gun's reaction slow, it almost went downhill.

Yvette Larois-Colleo's starting technique emphasizes body coordination.

When she started running, the movements of various parts of her body were very coordinated, and the rotation of her arms, legs and body were coordinated.

Through the overall coordinated movement of her body, she gained a greater forward momentum at the starting stage.

Moreover, her starting action has a strong sense of rhythm, which allows her to maintain a steady speed increase at the start. This advantage of body coordination enables her to quickly get into the state at the start and prepare for the subsequent acceleration stage.

The shoulder joint, hip joint, and ankle joint form a "three-joint coaxial" at the moment of extension.

The angles are 170°, 165°, and 85° respectively.

The power transmission efficiency reaches 91%.

Vestibular system sensitivity increased by 20%.

The semicircular canals sense changes in body posture.

Adjust the push-and-stretch force ratio in real time.

The idea is actually very good, but...

The serious injury she suffered in 04 has destroyed the coaxial mobility of the three joints in her body.

She will never be able to return to the scene of Supergirl.

Now, don’t even mention 10.77, even if it’s 11 seconds.

They are all within her ability.

That’s why it is important to develop scientifically and avoid getting hurt.

Because of an injury.

That will be a big problem.

It may even leave hidden injuries that are difficult to heal and destroy your entire future potential.

You can see that these people all have their own strengths.

Everyone has their own methods.

but.

The most resourceful one among them...

It’s still Chen Juan.

Chen Juan was the only contestant who used bent-arm start.

When she started running, her arms were bent at a certain angle and placed on both sides of her body.

When the gun went off, she swung her arms back quickly and pushed off the starting blocks with her legs.

The principle of this starting method is to use the reaction force generated by the backward swing of the arms to increase the forward propulsion of the body.

From a physics perspective, according to Newton's third law, the action force and reaction force are equal in magnitude and opposite in direction. By swinging her arms backward, Chen Juan obtained a forward reaction force, allowing her body to accelerate forward faster.

Moreover, this bent-arm starting method allows her to gain greater acceleration at the moment of starting, allowing her to quickly overtake other runners.

I saw her arms bent 120 degrees.

When the gun is fired, it swings back at an angular velocity of 240°/s.

The backward impulse is 18N·s.

According to the law of conservation of momentum, the forward recoil Δv=0.36m/s is obtained.

The activation degree of the pectoralis major and latissimus dorsi reaches 85% of the maximum voluntary contraction, forming a rigid force transmission chain of "trunk-upper limbs" and reducing the energy leakage of traditional arm swing.

The projection point of the center of gravity is 15 cm away from the center of the front foot support surface, forming a "forward tilt moment".

By reducing the ground contact angle, more power is converted into forward momentum.

This is the starting point.

Let her be tall.

It can also be done during the startup phase.

Take advantage.

Bang bang bang bang bang.

After the start, the runners quickly entered the acceleration phase.

During this stage, the athletes need to continuously increase their stride length and step frequency to improve their speed as quickly as possible.

For example, Jeter.

Enter the acceleration zone.

The frequency of her leg movements gradually increased.

The stride length also continues to increase.

Her acceleration technique is characterized by the perfect combination of strength and rhythm. Every step is full of power while maintaining a steady rhythm.

By quickly pushing off the ground and swinging her arms, she pushes her body forward and accelerates. In this process, her leg muscles contract and relax quickly, generating a powerful explosive force that allows her stride to increase rapidly.

Moreover, her arm swinging movements are coordinated with her leg movements, which can effectively maintain her body balance while also providing additional propulsion for her legs.

From the perspective of sports physiology, she fully mobilized the fast muscle fibers in her legs during the acceleration phase. These fast muscle fibers have strong explosive power and can generate greater force in a short period of time, thereby rapidly increasing her speed.

During the acceleration phase, Okabare's forward lean angle gradually decreased, and she began to gradually adjust her body posture in preparation for running midway.

Her acceleration technique focuses on a steady increase in speed. She is not in a hurry to increase her speed to the maximum all at once, but achieves a steady increase in speed by gradually increasing her stride length and frequency.

After all, she is the tallest one among them.

Naturally, there are disadvantages in the front.

There's no way around it.

During the acceleration process, she is able to control her breathing rhythm well and keep her body supplied with oxygen, which helps her maintain muscle strength and endurance.

The leg movements are very smooth, and the landing and pushing off of the ground in each step are connected very naturally. This smooth movement can reduce energy loss and improve acceleration efficiency.

My basic skills have definitely improved this year.

During the acceleration phase, Muna Li fully utilized the advantage of her good leg elasticity, and every step was like the extension and contraction of a spring.

Her stride length increased rapidly while her stride frequency was maintained at a high level.

When accelerating, the elastic potential energy of the leg muscles is used to bounce the body forward and upward when pushing off the ground, thereby obtaining a larger stride.

Bang bang bang bang bang.

The body's center of gravity is controlled very well.

During the acceleration process, the body's center of gravity always remains at a stable height.

This makes the running movement more stable and can better exert its acceleration ability.

But I'm still old.

a lot of things.

Unable to control it as one wishes.

It's not as shocking as it was during its peak period.

During the acceleration phase, Stewart mainly increases her speed by increasing her stride length.

Her height advantage was fully demonstrated at this stage.

Her long legs allow her to take longer strides than other competitors.

Not to mention that when she accelerates, the force of her legs is very strong, which can push her body forward a long distance.

At the same time, her arm swing amplitude is also very large. Through the large arm swing movement, the body's moment of inertia is increased, thereby driving the body to accelerate forward faster.

During the acceleration process, you will even pay attention to adjusting your running rhythm, and adjust your step frequency and stride in time according to your physical strength and speed changes to maintain the best acceleration state.

Just this one scene.

Stuart's overall feeling.

Probably better.

It may be even better than the big brands mentioned above.

During the acceleration phase, Campbell Brown's running rhythm was very obvious, accelerating at a pace that was familiar to her.

The coordination between her cadence and stride length is very good, and each stride length increase is accompanied by appropriate adjustment of the cadence. When she accelerates, her body coordination is very good.

The movements of the arms, legs and body coordinate with each other to form an organic whole.

Through this coordinated movement, she can effectively use her body's strength during the acceleration phase to achieve a rapid increase in speed. Moreover, her acceleration process is very stable without large fluctuations in speed, which enables her to maintain a good state when entering the mid-run phase.

But it’s still the same sentence.

No matter how good the rhythm is.

You're not running fast enough.

Not at all.

Plus, Brown was deliberately let go this season.

There's nothing special about her here.

During the acceleration phase, Wei Yongli continued to take advantage of the starting blocks, and through quick ground-pushing movements and the rebound force of the starting blocks, she continued to increase her speed.

Her stride length and step frequency increased evenly. During the acceleration process, she paid attention to adjusting her breathing and running rhythm to keep her body stable.

Good leg muscle strength.

Able to continuously provide power to the body during the acceleration phase.

Moreover, when she accelerates, she will adjust her running strategy in time according to the conditions of the track and the positions of other runners to ensure that she can occupy an advantageous position during the acceleration phase.

But the best...

It’s still Chen Juan.

During the acceleration phase, Chen Juan's technical advantage of bent-arm start was further demonstrated.

Her arms swung rapidly, providing constant forward propulsion for her body.

Her stride length and step frequency increased very rapidly. During the acceleration process, her body center of gravity gradually increased and her body posture gradually adjusted to the transition posture of running in the middle.

When she accelerates, she uses the inertia generated by the swing of her arms to drive her body forward.

The force of her legs pushing off the ground is also very strong.

Able to quickly increase your speed.

The acceleration rhythm is very tight.

Thanks to the use of bent arms.

Hip extension range from 150° to 175°.

The knee flexion range is from 60° to 45°.

Create a "whipping" leg swing.

The angular velocity reaches 1800°/s.

The vertical component of the ground reaction force increases from 4.2 times the body weight to 3.5 times the body weight, and the horizontal component remains at 3.8kN, reflecting the technical style of "strong propulsion, weak cushioning".

At the same time, adopt "geometric growth"——

The stride length/cadence is always maintained around 1:2.3.

This is done by maintaining a fixed rhythm ratio, reducing the neural cost of decision making.

The arm swing frequency and the step frequency form a near-isochronous resonance of 1:0.96, generating an additional 5% propulsion force.

Twenty meters, thirty meters.

The vertical displacement of the center of gravity is only 30cm.

15cm less than regular players.

The order of motor unit recruitment is optimized by the "size principle" at a lower level.

That is, activate the small motor units (slow muscles) first.

After 30 meters, large motor units (fast twitch) are recruited.

Delayed onset of fatigue.

Bang bang bang bang bang.

Her running movements were very light.

This helps reduce energy loss and improves acceleration efficiency.

When she accelerates, she controls her running direction and speed by adjusting her body's center of gravity and the direction of her arm swing.

The acceleration process is very flexible.

Be able to adjust your acceleration strategy at any time according to the actual situation of the game.

Although Chen Juan was born in the 90s, she participated in the National Games with Su Shen when she was thirteen or fourteen years old.

Various competitions along the way.

It's also easy to do.

Adjustment capabilities.

I've practiced it a long time ago.

Her stride length and cadence have increased very steadily.

During the acceleration process, she also controlled her breathing rhythm very well.

Able to maintain the body's oxygen supply.

As she accelerates, she uses the rotation and swing of her body to increase her forward momentum.

Chen Juan didn't expect this either.

When she finished these, she raised her head...

I instinctively wanted to see which place I was in.

Who else is ahead?

result.

The scene left her stunned.

I almost thought I was in a horror movie.

front.

There was no one there.

No one.

No Jeter.

There is no Solomon.

No Brown.

Not even Muna Lee.

What does this mean?
This explains it.

Chen Juan’s wave.

Everyone is already under control.

Including various more famous bosses and generals.

Even the Olympic and World Championships champions.

It seems that...

Not as strong as imagined.

Then invincible.

otherwise.

Why aren't they ahead?
but yourself.

Think of this.

Chen Juan's whole body.

The temperament changes again.

Become more confident and...

Become fierce.
