The Su God of the Reopening of the Sports Arena

Chapter 2228 World Record… Another two-person trip
China Sports Channel.

“Dear audience, on the dazzling stage of world athletics, the men’s 100m race at the Diamond League Oslo is undoubtedly a feast that brings together top athletes.”

"This is Tianchao Sports Channel, this is Tianchao Sports Channel, I am your old friend Yang Jian, and I will still be the commentator for this game."

“Now the athletes are on the track.”

"Bolt, Carter, Blake, Powell, Lao Yi, Zhang Peimeng, Vicaut and Lemaitre, these eight athletes, each represents their own glory and brilliance. They stand on the same starting line and are about to start a peak competition of speed and technology."

"Let's see who has the last laugh."

"Although it is highly likely that it will be Bolt, competitive sports may have different results. Moreover, even if we know that Bolt can win, whether he can fulfill his pre-match promise to break the world record and regain ownership of the world record is also a highlight of this game."

"Okay, enough talking, the game is about to start, let's put aside our time and watch this wonderful shot."

On your marks.

The electronic password sounded.

Every athlete in the lane has made good preparations.

Nesta Carter's body was tense and his attention was focused on the starting gun. The angle of his starting blocks was carefully adjusted to allow him to achieve the best angle of force when pushing off.

He even took out a small tape measure like Su Shen to measure the starting blocks before the game.

This posture really looks like Su Shen before 2021.

Looks very much like Su Shen in 2018 in his previous life.

It’s just that people don’t have this impression now.

Because of Su Shen in this timeline.

It has already reached the level of lightning.

It can be seen.

Maybe it’s only Su Shen.

he himself.

Before Lao Yi started running, his eyes were firm and he was focused on the race. His starting block settings were adjusted according to his height and leg strength.

When Vicott starts running, he keeps his center of gravity low, which increases his stability and explosive power at the start.

When Le Metrie started, his expression was serious and he was fully focused. His starting technique focused on the rhythm of the start and the continuous output of power. At "On your marks", his body trembled slightly, indicating that he was accumulating strength.

Bolt starts from a crouch position, and his starting "ready" posture is quite distinctive.

The center of gravity has obviously moved forward, and the shoulder joint projection is slightly beyond the starting line. This posture enables him to gain greater forward momentum at the moment the gun sounds.

It is also to make better use of the three-joint torque power drive technology.

set.

Bang————————

Gunfire rang out.

Carter rushed out quickly, and after the gun went off, his arms swung quickly, as powerful as pistons, providing additional power for the extension of his legs.

When the legs exert force, Carter's hips actively move forward, making his first step stride larger, allowing him to quickly rush away from the starting line and quickly gain initial speed with efficient starting techniques.

Powell's starting technique is textbook-level.

His starting posture was stable, his body center of gravity was reasonably distributed, and he was fully prepared before the gun went off.

When he started running, his legs extended evenly and powerfully, and he controlled the timing and rhythm of the extension just right.

Swing your arms with a moderate range.

Coordinate with leg movements.

Make his starting motion smooth and natural.

When Powell took his first step, he quickly transitioned from landing on his toes to landing on the sole of his foot.

This landing method can quickly obtain the reaction force of the ground, pushing him forward and accelerating.

As for Lao Yi, after the gunshot, he quickly got rid of the static state by quickly extending his legs and swinging his arms vigorously.

Lao Yi paid attention to his body balance and coordination when he started running. During the acceleration process, his body remained stable without any obvious shaking.

This allows him to convert more power into forward speed, opening up the race with a solid starting performance.

On Zhang Peimeng's side, gunshots were heard.

Zhang Peimeng's starting technique combines the characteristics of Asian athletes and has been improved by Su Shen. After years of practice, he focuses on the reaction speed of the start and the coordination of rapid gear switching when starting.

In the "ready" position, his body leaned forward slightly, ready to explode at any time.

Zhang Peimeng's arms swing powerfully and with a large amplitude, which can effectively drive his body forward. In the starting phase, he fully utilized his advantages of quick reaction and agile movements and quickly caught up with the pace of other top players.

After the gun went off, Vicott pushed hard off the starting blocks, his leg muscles tensed and he exploded with tremendous force, making his first step a larger stride.

During the start, Vicott focused on using the power of the hip joint.

Through rapid rotation and forward thrust of the hip joint.

Drive your legs forward quickly.

Use strong starting power to lay the foundation for subsequent acceleration.

Le Metri's side is not strong enough and has suffered some minor injuries recently. With the World Championships approaching, he doesn't have much time to waste.

The gun went off and he pushed off the starting blocks with even force the moment he started running.

The pushing force of the legs gradually increases.

It's not an instant burst of full strength.

This starting method makes his acceleration process after the start relatively smooth, and he can continuously increase his speed.

It avoids the problem of subsequent lack of strength caused by the instantaneous burst of strength.

Each one has his or her own characteristics and features.

This level.

There is no such thing as absolute karaoke.

Carter got to the front.

I only saw his hip extension angle, and the angle between his thigh and torso was optimized when he stretched.

The knee joint buffer angle optimizes the angle between the calf and thigh when landing.

The plantar flexion angle of the ankle joint and the angle between the sole of the foot and the calf are optimized during extension.

It turned out to be one of Su Shen’s core technologies in 18.

Lower limb joint angle chain.

Carter.

It's really something.

It’s really thoughtful.

Otherwise, it wouldn’t be so easy to find the core feeling.

Su Shen looked at it and nodded silently.

He relied on this, plus his own outstanding talent, and the fact that Old Bao was still recovering.

Su Shen didn't come either.

He finally got the first position in the start.

Rectus femoris, knee extension.

Hamstrings, knee flexion.

Synergistic shrinkage ratio.

This is called the "superisometric preloading" technique.

It is to utilize the lower limb joint angle chain mentioned above, and actively contract the quadriceps 0.1 second before the gun is fired. If all goes well, the maximum pre-tension can reach 30% of the maximum muscle strength.

Then the stretch reflex was used to increase the initial speed of the push-off by 0.3 m/s.

The H reflex latency is only 28ms, compared with 40ms for ordinary people, and the spinal reflex pathway is optimized.

Enhance startup capability and stability.

This kick goes out.

Carter felt stable!
Su Shen is not here.

Myself now.

The monkey is the king!
"In terms of starting, Carter...gets the high position first!"

Then when Carter accelerated, the combination of stride frequency and stride length was very reasonable.

He accumulated initial speed through a fast step frequency, and then gradually increased his stride length to achieve a rapid increase in speed.

Carter's leg extension strength continued to increase, and with each step he was able to quickly shift his body's center of gravity forward, using the reaction force of the ground to propel himself forward.

Cutting into the acceleration position, his arm swing is compact and powerful, coordinating well with his leg movements, making his movements in the acceleration phase smooth and natural, and his speed increasing rapidly.

It looks like everything is fine.

Carter felt the same way.

Pretty good.

Just ...

Even so.

His protagonists experience time.

It’s about to expire.

because.

Right on his right.

The real protagonist.

debut.

Lao Bao is entering the acceleration run.

Although he didn't want to argue with these people, it was not the right time yet.
When you are accelerating after your comeback, just aim to make sure your technical movements are standard and smooth.

He is also an experienced veteran.

This is still very clear.

It won't be the same as before.

So when I come back, I want to achieve some results immediately.

Make some big noise.

Lao Bao's stride length and step frequency increased steadily. He tried to achieve a steady increase in speed by constantly adjusting his rhythm.

There wasn't even much of an explosive start in this game.

That is, during the acceleration process, pay attention to the strength and angle of leg extension.

Hopefully, every step you take will fully utilize the reaction force of the ground.

Push yourself forward.

In terms of arm swing, his arm swing movement has a moderate amplitude and a frequency that matches his stride frequency, which keeps his body balanced while also providing additional power to his legs.

Everything is proceeding in an orderly manner.

That's when.

There is a dark shadow.

Also suddenly appeared from the side.

Powered by a terrifying motor.

With this tall dark shadow.

Speed ​​ahead.

The start is actually very good, but Carter has evolved again this year, but Carter is here...

Behind.

It will completely become Usain Bolt's stage.

During startup.

Bolt mobilizes the coordinated torque output of the hip, knee and ankle joints to form a "chain power transmission system."

After taking the step.

Four points connected.

Bang bang bang.

Take four steps in succession.

Gluteus maximus, hip extension.

Gastrocnemius, ankle plantar flexion.

Quadriceps, knee extension.

Finally, the characteristics of "sequential activation-synchronous peak" are presented.

The total power of the three joints during the extension phase reaches 3500-4000W, which is 20-25% higher than that of athletes of the same weight!

Su Shen was distracted and glanced at Carter for less than half a second.

Immediately returned to the focus of observation of this game——

Bolt.

Bolt's start time is not outstanding, which is 0.155s.

Not bad.

But how much advantage can you gain by relying on this starting reaction?

You're also thinking too much.

It still depends on running.

It still depends on the pure running stage.

Start the reaction.

Bolt simply can't give a particularly good answer here.

But technically.

He still did it.

Quite accurate.

Bolt is not the same person this year.

Mills is satisfied with the aspect.

Because it's not just about self-discipline.

There is.

As long as Bolt is self-disciplined and works hard, it will bring other additional consumption.

For example--

The growth of technology.

Bolt's running was relatively rough in the past.

Mills also knows this.

But with Bolt's training attitude, he can achieve this, which is the limit of his planning.

He can only maximize the limited time as much as possible and cannot spend it on too many details.

When it comes to training, if the athletes don’t cooperate, no matter how good the coach is, it will be useless.

And even so.

Bolt still did a good job in terms of technology.

At least that's how Mills sees it.

This kind of dedication and this kind of training attitude can yield such skills...

The input-output ratio is already amazing.

It's just that other people don't know this.

From the perspective of hard work and self-discipline, Bolt's skills are certainly not enough, but if you know how much effort Bolt has put into this aspect...

There may be others.

feel.

Just like now.

In terms of starting, Bolt burst out with a hip torque!

The focus of this technique is that the hip extension torque dominates the initial acceleration.

boom.

Hip extension torque, 185 N·m, body weight 100 kg, moment arm 0.18 m.

Knee extension torque, 110 N·m, quadriceps eccentric contraction cushioning.

Ankle plantar flexion torque, 95 N·m, when the forefoot pushes off the starting blocks.

The power transmission mechanism is that the gluteus maximus contracts explosively at 85% of its maximum voluntary contraction.

The hip extension angular velocity was 450°/s.

The torque is converted into horizontal thrust through the femoral long lever, so that the initial starting speed can reach 2.3m/s.

If you don't understand how well Bolt did here, compare him with, for example, Zhang Peimeng.

Zhang Peimeng's hip joint torque at the same stage was only 130 N·m.

This is certainly due to the fact that his femur is 47cm long.

Can I be affected by an 18% smaller muscle cross-sectional area.

Here, Bolt fully utilized his starting leverage advantage as a tall athlete.

tall.

Are there any startup advantages?
Isn’t this nonsense?

can.

he is.

Bolt.

Then everything is possible.

Speed ​​up and run.

Three joint torque coordination!
Continuous output of hip joint torque + ankle joint elasticity participation!
Bang bang bang bang bang.

Twenty meters.

Hip extension and ankle plantar flexion are in "phase synchronization", forming a "push-off" compound action.

The gastrocnemius-Achilles tendon complex stores elastic potential energy with a stiffness of 140N/mm. At the end of extension, 35% of the stored energy is released, increasing the propulsive force by 120N per step.

If we had real-time data from high-speed cameras, we would be able to see—

Bolt during this period.

The sequence of the extension angles of the three joints during the support phase is:

Hip joint 165°→185°.

Knee joint 140°→175°.

Ankle joint 90°→150°.

It forms a "whip-type" torque transmission chain.

Compared with the knee-dominant type like Vicott, the direct efficiency is 9% higher.

"Bolt has rushed out!"

Thirty meters.

Bolt was ready to look up.

Take pictures on the way in.

Look up.

There is wilderness ahead.

No man's land!
This means he is already ahead.

Run on the way.

Three joints switching, ankle joint power dominant!
Seeing that Bolt could independently switch between three joints to transform dominance in actual combat, Mills couldn't help but nod.

This talent...

That's good. Maybe I can't understand so much professional knowledge.

Compared with Su Yi, he is not smart enough.

but……

You can't resist them and you will understand as you run.

you say.

Isn’t this infuriating?

pity.

This kind of people.

There is no replicability.

It all depends on talent.

Bolt uses ankle plantar flexion to maintain high speed.

Joint torque evolution.

The hip joint torque is reduced to 120 N·m, and the body is kept leaning forward.

The ankle joint torque was increased to 150 N·m, and the plantar flexion angular velocity was 600°/s.

Knee joint torque, 80 N·m, isometric contraction to maintain support stability.

This.

Isn't this what Mills wanted?
OK OK.

Usain.

This.

That's how you should be.

Mills is excited.
My ideal Bolt.

Finally started.

Gradually they overlap in reality.

Bang bang bang bang bang.

Ankle plantar flexion power reaches 1500W.

Of this, 42% comes from the recovery of Achilles tendon elastic potential energy.

This place is 15% higher than Lao Baodu.

Used to reduce direct muscle energy consumption.

At this time, the sliding speed of the gastrocnemius muscle fibers reaches 4.0μm/s.

Close to the optimal efficiency range of type II muscle fibers, 3.5-4.5 μm/s.

Forty meters.

The total power of the three joints is 3200W.

The ATP consumption is about 55 μmol/g/s.

The CP reserves and creatine kinase activity in Bolt's muscles allow him to maintain this power output for more than 6 seconds.

Can a little more.

Ok.

That's a whole change of speed.

Means your top speed.

Has higher possibilities.

Bang!
Rapid explosion!
"Bolt...speed has reached a new level!"

"Oh my god, the ultimate sense of speed, this is Bolt, Black Lightning Bolt!"

The on-site commentator also started shouting.

It's just too fast.

People watching.

I can't help but get my blood boiling.

The third stage of the six-second burst seems...

It has also reached a higher level.

pity.

There was no one to compare him to.

Everyone can only feel that it is so fast.

How fast exactly.

And can't feel it.

At this point, the game had actually lost its suspense and no one could catch up with him.

Carter had already been left behind.

Powell is still recovering and doesn't want to fight hard.

Guy is not here.

Su Shen is not here.

That is Blake.

This place has just exploded and still has a lot of energy left.

But Blake wasn't running fast enough in front of him.

This is only within 100 meters.

There wasn't enough time for him to catch up.

Not to mention his extreme speed.

Not fast enough.

Bolt had already secured victory at this time.

But being assured of victory is… not enough.

He didn’t come here to win.

He is coming over.

Breaking the world record.

Bang bang bang bang bang.

Entering the later stage.

Bolt relies on the torque of three joints to continue maintaining a very high speed.

Even at this time, the overall speed has passed the highest point and started to decline.

That's okay too.

Try to delay him as much as possible.

Torque attenuation and compensation.

Take compensatory lift of hip joint torque.

The hip joint torque increased from 120 N·m to 140 N·m, and the gluteus maximus recruited more motor units.

Ankle joint power decreased by 12%, and the utilization rate of Achilles tendon elastic potential energy decreased to 35%.

The knee joint angle and cushioning depth increased by 10°, and the eccentric contraction load of the quadriceps increased.

With this adjustment, the body's fatigue attenuation is also reduced.

Bolt has indeed run more technically this year than in any previous year.

And he has mastered Mills and has always wanted him to master this technique.

And it gets better and better.

The skills are becoming more and more mature in actual combat.

This talent.

Mills was so shocked by the sight that he pinched his arms with his fingers.

The muscles are deformed.

But he himself didn't feel it.

Because he has been trapped in Bolt at this time.

Completely attracted attention.

after all.

This is a work of art created by him.

The more successful Bolt is.

The more successful he is.

The stronger his sense of accomplishment.

Bang bang bang bang bang.

Seventy meters.

Neuromodulatory strategies.

The firing frequency of spinal motor neurons increased from 130Hz to 150Hz.

Forced recruitment of type IIx muscle fibers.

This causes the blood lactate concentration to exceed 12mmol/L, nearly double the amount during mid-run.

In doing so, Blake, who was in second place, was caught up.

Because Blake has a shorter stride, the load on his ankle joints in the latter part of the race is 18% lower than that of Bolt.

The torque attenuation on Bolt's side is only 8%, which shows the stability advantage of athletes with long strides in the later stages.

The last twenty meters.

Now, everyone sees it clearly.

What exactly does Bolt want to do?
Torque reorganization and finish line optimization!
Hip torque steering forward control!
Joint function conversion!

To combat fatigue, the hip joint switches from a propulsive moment to an anterior tilt moment.

The torque direction is tilted forward 15°.

Produce a head-down movement.

Prepare to press the line.

At the ankle joint, the plantar flexion torque drops to 60 N·m, which only maintains the body balance.

Save energy for other parts.

Make way for other work-doing parts.

Knee joint, flexion torque 40 N·m, brakes the forward thrust of the trunk.

This is also to prepare for the finish line after 90 meters.

After this set of processes, Bolt is more prepared to cross the finish line than at any previous time.

Mills watched, already excited.

He felt that this shot must have performed well.

Ninety meters!
At this time, thanks to the three-joint torque power technology, Bolt's type II fast muscle fibers accounted for 79% and the cross-sectional area of ​​the muscle fibers reached 9000μm.

35% higher than Zhang Peimeng.

15% higher than Lao Bao.

30% higher than Carter.

10% higher than Blake.

The maximum tension of a single muscle fiber is 50mN!

You should know that the normal selection here usually only leaves 35mN!

Maybe Blake is really the best in the world in the back half of the 200 meters.

But the world's best back leg of 100 meters.

Not his.

It's Bolt.

Belongs to Usain Bolt!!!
Ninety-five meters!

During maximum voluntary contraction, the synchronous activation rate of type I muscle fibers is 92%, which is much higher than the 75% of ordinary athletes.

To ensure the synchronous peak torque of multiple joints.

The density of plantar muscle spindles is 150/cm.

20% higher than Blake!

Complete joint angle fine-tuning within 0.03 seconds during the support period!

Ordinary athletes need 0.05 seconds or even more!
at this time.

Bolt already sees the finish line ahead.

It's becoming clearer and clearer.

at this time.

The accumulated torque of the three joints in front of Bolt came into play.

The forward moment of the hip joint causes the torso to press the line at an 18° angle!
The center of gravity moves forward 0.28m!

Compared with old abalone, the 20° angle covers 0.03m more!

At the same time, the knee joint is slightly bent to present 160°!

To reduce the impact of landing!
Come!
Press the line!!!!
call--------

Usain Bolt...

Press the line! ! !

The result is...

As soon as the results come out.

The commentator on the scene was already ignited.

Shout loudly.

Afraid that others won’t hear.

“9.50!!!!!!!!!”

“It’s 9.50!!!!!!!!”

"Bolt tied the world record!!!!"

"Now the world record is no longer held exclusively by Su!!!"

"It's become two again!"

“Just like the Olympics.”

"Su one!"

"Usain Bolt one!"

"Wind speed 1.3m/s."

Bolt looked at it and was still a little dissatisfied.

But there is no stimulation from opponents.

It can be like this.

It seems pretty good.

Just accept it reluctantly.

A lightning-shooting sun move.

Light up the place!

When being interviewed.

He even directly called out:

"Su, now I am also a world record holder."

"There's still so much time until the competition, you won't be hiding forever, right?"

"Come out and fight me in the next game!"

"I'll wait for you in Lausanne!"

“They are all world record holders!”

"Let's see whose reputation is stronger!"

"Su!"

“Come to Lausanne!”

"Let's fight!!!"

This side of the TV.

Zhao Haohuan looked at him, then looked at Su Shen next to him.

At this time Su Shen.

There was still no sign of hesitation or indecision on his face.

Zhao Haohuan only saw it reflected in the light of the TV screen.

Su Shen.

It seemed as if he licked his lips slightly.

Like the hunger of a wild animal before it attacks.

It's like avoiding certain foods before a big meal.

for.

Just have a big meal.

To eat better.

The food tastes better.

Eat more happily.

prepare for.

"Okay."

"Usain."

"Then let's."

"See you in Lausanne."

Su Shen is looking at Bolt on TV.

Bolt, who had just equaled his world record.

The sound is neither high nor low.

Said it in a neutral tone.

Even so.

Zhao Haohuan beside him suddenly felt a little cold.

Because of this guy's expression.

No matter how you look at it.

Not worthy of this voice.

Apparently so.

I'm trying hard to suppress the excitement in my heart!
Zhao Haohuan:......

monster.

They are all monsters.

These two are monsters.
