The Su God of the Reopening of the Sports Arena

Chapter 2247 Lightning Showdown Begins! Bolt's New Technology Strikes Back

Lausanne Stadium.

"This is Tianchao Sports Channel. Welcome back, everyone. The final men's 100m final of the Lausanne Battle is about to begin."

“Now the athletes are on the playing field.”

"The first one is Zhang Peimeng."

"The second Nesta Carter."

"The third one is Tyson Guy."

"The fourth one is Usain Bolt."

"The fifth Su Shen."

"The sixth one is Yohan Blake."

"The seventh one is Zhao Haohuan."

"Powell, the eighth."

"The ninth level of labor and leisure."

“I believe that people who often follow athletics should be familiar with these names.”

"They are all the best of this era, and each of them has achieved excellent results."

Yang Jian casually cited these data and said, "The worst ones here are 9.80+."

"That means even 9 seconds is not enough to qualify for this race."

“I don’t know when it started, but the threshold for track and field sprint events has become increasingly higher.”

“Before, breaking 10 was enough to get into the finals of a major tournament.”

"Now you can't get into a Diamond League final even if you run 9 seconds."

"This match is definitely worth watching. All of them are members of the 9.80+ club. What does this mean? It means that everyone has extraordinary abilities."

"But I believe that even with so many painters, there are only two people who stand out the most on the field..."

When Yang Jian was speaking, the director's camera just happened to close up the 4th and 5th tracks, and he just happened to say along with the camera:

"Bolt in lane 4 and Su Shen in lane 5."

"Just like the official promotion of this game."

“This one is in Lausanne.”

“This is a blitzkrieg.”

"It is very likely that the first person in human history to break 1 seconds in a legal wind speed will be selected."

"If you are a new audience, let me give you a brief introduction to the 100-meter track and field event this season. It can be said that the flag is constantly changing."

“The identity of the world record holder keeps changing.”

"This has never happened since Bolt established his absolute dominance."

"Although Bolt has now nominally regained his status as the world record holder, this status does not belong exclusively to him."

“That’s what makes this season so intense.”

"Because Su Shen's results are already at the same starting line as his."

"If he can't prove he's faster."

"Then his absolute dominance will be shaken in the future."

"Or it has been shaken, starting last year."

"But Bolt is not a pushover either. He has worked extremely hard this year after winter training. We can see that he has maintained a very good figure and is even in better shape than last year."

"And to be honest, this year he and Su Shen will compete on the same field..."

“And they have basically won.”

Yang Jian did not hide anything here and said directly: "This shows that Bolt is still very strong. He can't be careless just because Suarez won the Olympics last year."

"Especially after running a new world record of 9 seconds on the Su Shen Plateau, Bolt seemed to be stimulated..."

“I ran four or five 9.50+ races in a row.”

"Based on this state, it can be said that Suarez has inspired the best of Bolt."

"Then be the holder of two world records."

“When we were standing on the same playing field.”

"Who will win the game?"

"Please let us wait and see."

"A lightning showdown between red and black."

“It’s about to begin.”

"Let us hold our breath and appreciate the fleeting moment that follows."

Done.

At this time, the athlete has finished the trial run.

They all returned to their positions.

On your marks.

The electronic password sounded.

Both Bolt and Su Shen have bent down.

Almost everyone's eyes were focused on the two people in the middle.

It's really not disrespect to other people.

That is when these two people are present.

There is really no way to divert my attention away.

These two people seem to have their own spotlight effect.

Not to mention the audience.

Even the audience all over the world.

Watch it via TV, Internet and mobile phone.

Who wouldn't focus all their attention on them?

9.50vs9.50.

The ultimate shot.

Right now.

set.

Bang——————

Zhang Peimeng reacted the fastest.

My feet are firmly on the starting blocks, like a spring about to explode.

His starting posture focuses on the balance of the body's center of gravity, with the front leg knee bent at a moderate angle, the hind leg straight, the body slightly leaning forward, the head kept stable, and the eyes fixed on the front.

The moment the starting gun sounded, he relied on his excellent reaction nerves to quickly push off the starting blocks, swinging his arms back and forth vigorously to drive his body forward.

It's like a racing car suddenly shifting into third gear.

Force start.

The core of his starting technique lies in the instantaneous release of explosive power, which achieves the maximum initial velocity through the rapid contraction of the leg muscles.

In a word.

Big butt.

It’s not a waste of practice.

Zhang Peimeng's dual-phase drive technology splits the starting power process into a preload phase and an explosive propulsion phase. In the preparatory stage before the starting gun sounds, he enters the preload phase: the front leg knee bending angle is precisely controlled at 105°-110°, and the back leg is bent to 135°. This angle setting allows the quadriceps, gluteus maximus and calf triceps to form an elastic potential energy reserve state, just like a compressed spring.

His feet are on the starting pedals, with the forefoot accounting for 70% of the force distribution and the back of the foot accounting for 30%. By adjusting the force distribution on the soles of the feet, the storage of muscle elastic potential energy is maximized.

When the gunshot sounded, he reacted immediately and his body entered the explosive propulsion phase. Zhang Peimeng's legs followed the force logic of "stretching first and then pushing": the front leg knee joint stretched first and quickly stretched, using the contraction force of the quadriceps to push the body forward and upward.

At the same time, the hind leg uses the ankle joint as a fulcrum, and the calf triceps contract strongly, forming a pushing force backward and downward.

These two forces act at different time points. The extension force of the front leg establishes the initial forward velocity of the body, while the extension force of the hind leg further increases the acceleration, driven by a two-phase relay.

Kick out.

Landing.

Four points connected.

The top of the head, shoulders, hips, and heels form an almost vertical line of force.

Reduce air resistance.

Optimizes power transfer.

Maintain balance and stability.

Bang bang bang.

Four steps in a row.

The run felt better than he had imagined.

Even better.

Next to him is Nesta Carter, known as the "Jamaican starting machine".

Carter's starting technique is also unique.

His starting characteristics are quick reaction and great explosive power.

The moment the gun went off, his body was almost parallel to the ground when he started running.

This low posture allows him to gain greater forward momentum at the moment of starting.

In addition, the power of his feet pushing against the ground was huge, like the boosters of a rocket launch, which quickly pushed his body out.

At the start, Nesta Carter is now the improved version of Suarez in 2018.

Not only did he continue his signature "low-profile explosive" starting style, but he also incorporated reference and improvement on Suarez's straight-arm starting technique.

Its core technology lies in the "dynamic pre-squat" and "straight arm linkage" mechanisms.

On this basis, Carter adjusted the spacing of his starting blocks from the traditional "one and a half steps" to the "one step plus half a step" adopted by Su Shen. This shortened spacing design enables him to more efficiently convert the explosive power of his leg muscles into horizontal forward momentum at the moment of pushing and stretching.

In terms of body posture control, Carter borrowed the essence of Suarez's "straight-arm start", but made adaptive improvements based on his own body characteristics. In the preparatory stage, he reduced the angle of his arms from the conventional 120 degrees to 95 degrees, with his elbows close to the sides of his torso. This compact arm swing starting posture not only reduces air resistance, but also allows him to complete the first arm swing acceleration in a shorter path when the starting gun sounds.

Slightly different from Suarez, Carter swings his arms upward at a nearly vertical angle when pushing off the ground.

Use the reaction force of the upper limbs to drive the torso to lean forward quickly.

This is also because he is shorter.

Modifications need to be made according to your own physiological conditions.

To copy it is like looking for a sword on a boat.

This "upper limb traction" starting method increased the speed at which his center of gravity moved forward by 12%.

In addition, Carter will take a short, powerful breath just before the starting gun sounds.

Use your abdominal muscles to further stabilize your core.

At the same time, when pushing off the ground, coordinate with the short inhalation rhythm so that the body can form a synergistic effect of "breathing-muscle contraction" at the moment of starting.

Carter started so domineeringly this year.

It can almost be stabilized within 1.85, and if you are a little more serious it can reach 1.80.

It cannot be ignored.

No skills.

This season can be revived in a big way.

It also shows that he did see into Su Shen's things.

Thought deeply about this.

and optimization.

Otherwise this effect cannot be achieved.

Although Guy also made changes, with the elastic potential energy release mechanism as the main factor, the bending angle of Guy's front leg knee joint reached about 110°-120°, far exceeding the 90° standard of the conventional squat start. This super-physiological flexion angle puts the quadriceps, iliopsoas and other knee extensor muscles in a highly stretched state, forming an elastic deformation similar to a spring.

This is to allow your muscles to quickly release elastic potential energy in a eccentric-concentric contraction coupling mode when the starting gun sounds, generating an instantaneous ground-pushing force of about 4.2-4.5kN, which is 15%-20% higher than that of ordinary athletes and a significant improvement over your own performance.

When starting, the angle of the legs pushing the ground outward is 38°-42°, which effectively reduces the ineffective work in the vertical direction by increasing the proportion of horizontal force.

This design allows Guy to move his center of gravity forward faster than before.

can.

He entered the state last year.

Plus, I’m not an expert at starting things.

Therefore, no matter how much it changes, it will never be able to start up that powerfully.

At least among this group of people.

It's impossible to be that awesome.

Therefore, before the gun goes off, he will move his center of gravity slightly forward, with his shoulder joints projected to or slightly beyond the starting line. This posture helps to gain forward momentum at the moment of starting and reduce the resistance of the body leaning back.

The hind legs also maintain proper bend.

In order to push off the ground forcefully.

He starts with his legs wider apart, which gives him a smaller footprint with each step but allows him to better push against the ground to maintain forward motion.

After the gunshot, Guy pushed out with his hind legs first, and at the same time, he quickly pushed out with his front legs, using the elasticity of his leg muscles and stored elastic potential energy to bounce his body up.

His back kick was sufficient, but his condition had not yet fully recovered, and it did not form a straight line with his torso. However, the foundation was there, and he could still generate a strong forward thrust.

The angle at which Gay's legs push the ground outward when he starts is unique, mainly to better generate thrust with the ground to maintain forward motion, which is different from some other runners.

in fact.

It can be said that it has completely surpassed his previous start.

But in this venue, there are too many masters of starting.

It seems that he has made improvements.

also still...

Not fast enough.

Even a little slow.

Especially Zhang Peimeng next to him relied on his reaction.

Carter relied on learning Su Shen's techniques.

Two heroes compete.

It seems...

Even slower.

It wasn't just Carter who was around.

And Carter's fellow countryman.

The absolute protagonist of this game, Usain Bolt.

Bolt's starting technique this season is unique.

Despite his size, he makes up for his high center of gravity with a unique starting stance.

When he started running, he leaned back slightly, raised his head, and looked into the distance.

This position may seem counterintuitive, but it allows him to better utilize his body's inertia at the moment of starting.

Bolt has amazing leg strength. The force with which he pushes off the starting blocks is like a cannonball. His powerful explosive power enables him to quickly distance himself from his opponents at the start.

The core of his starting technique is to utilize the overall coordination of the body to perfectly combine the strength of the legs, hips and upper limbs to achieve an efficient start.

and.

He also came up with something new.

It's not exactly brand new.

It has been shown before, but this is the complete version, the real look that Mills wants him to show——

Backward inertial launch system.

The name sounds counter-intuitive.

You have to press forward to start, so why is it leaning backward?
This is because this technical move is set according to Bolt's victory conditions.

Mills has done an experiment and found that Bolt is too tall. If he presses forward too hard, it will actually be detrimental to quickly entering the acceleration position.

Because the higher you are, the harder it is to control your center of gravity and the harder it is to adjust.

A small athlete can hold down the center of gravity, but for you... it's too difficult.

and so.

It’s better to optimize it.

Let Bolt start at the moment, you can better bring in your own physiological attributes.

Asymmetry of pressure distribution between the two feet.

When Bolt started running, the pressure center of his feet showed a significant difference between the left and right sides: the peak ground-strike force of his right leg reached 1080 pounds, 13% higher than that of his left leg.

The left foot is on the ground 14% longer than the right foot.

This asymmetric distribution is caused by scoliosis, a physiological characteristic in which the right leg is slightly shorter.

Mills wanted to extend the support time of the left leg so that the pressure center would shift about 15-20 cm to the left front at the beginning of the start, forming a unique "left-leaning propulsion vector".

Then move the pressure center toward the three-dimensional migration trajectory.

first step.

The pressure center forms an internal rotation angle of 8°-12° in the coronal plane, offsetting the center of gravity shift caused by height through the external rotation torque of the hip joint.

Maintain the forward lean angle of the torso at 18°-20°.

Compared with normal players, the invalid rotation is reduced by 5°-8°.

The second step.

At the moment of contact with the ground, the pressure center quickly sinks to the rear edge of the sole, about 3 cm away from the calcaneal tubercle, and then migrates forward at a speed of 2.1 m/s.

It reaches the lowest point in the middle of extension, about 8 cm from the ground, forming a "U-shaped" vertical trajectory.

This design converts about 32% of the pushing force into elastic potential energy for reuse through the elastic energy storage mechanism of the Achilles tendon.

At this time, if you rush out too hard, the imbalance between the long and short legs will be obviously manifested in the process of going from static to high speed.

This is also the start of Bolt, who often depends on the weather for his meals.

One of the reasons for instability.

But things are different now.

Bolt leaned back slightly through his body.

The angle between the torso and the ground is about 45 degrees.

and head-up posture.

Move the center of gravity projection point back to the center of the starting block support surface.

A dynamic inertia moment balance system is formed invisibly.

Mills is indeed a man of some talents.

No wonder I always felt that Bolt was "unpleasant to the eye" and "not working hard" before.

Because he thought Bolt could do better.

I don't think this is Bolt's limit.

This design enables the center of pressure to generate an initial backward momentum of approximately -0.3kg·m/s at the moment of starting, followed by rapid extension of the front leg.

The knee extension angular velocity was 170°/s.

Transformed into forward propulsion.

The fluctuations of the body are actually...

Instant integration.

A lot more stable!

Then take the third step when you are more stable.

Double-foot coordinated force chain!
third step.

The front leg knee flexion angle is 115°-120°.

The quadriceps femoris releases elastic potential energy in an eccentric-concentric coupling mode, generating an instantaneous ground-pushing force of 3.8-4.2 kN.

The center of pressure quickly moves forward to the middle of the forefoot.

the fourth step.

The extension angle of the hind leg knee joint increased from 130° to 175°, and the gluteus maximus activation time was 0.02 seconds earlier than the quadriceps femoris.

Form a "hip-thigh synergistic force chain".

The center of pressure shifted approximately 5 cm to the outside of the left leg.

Generates an additional 0.8-1.0kN of lateral thrust.

Then through extensive training, the neural control of the migration of the pressure center can be established.

By monitoring the changes in ground reaction force in real time, the foot contact angle and muscle activation timing are dynamically adjusted.

If we look at the segmented pressure center trajectory comparison, it is——

First four steps.

The migration speed of the pressure center is 5.8-6.2m/s.

The trajectory curvature radius is 0.8-1.0m.

Then coordinate the body posture and the migration of pressure center.

Bolt's posture of leaning back slightly and raising his head not only affects the projection point of the center of gravity, but also closely coordinates with the migration of the pressure center of both feet. The leaning back posture makes the body form a specific posture angle at the moment of starting, which, combined with the shift of the pressure center of both feet, can better guide the power transfer.

This will also tighten your neck muscles further.

The neck muscles are in a proper state of tension, which can provide support for the stability of the overall posture.

This ensures the accuracy and efficiency of pressure center migration.

Then start stretching continuously.

Bang bang bang.

the fifth step.

Adjust the lever arm length.

Increase leverage usage.

According to the principle of lever, the longer the lever arm, the greater the force generated under the same torque.

When starting a race, you can change the length of the lever arm by adjusting your body posture and limb position.

For example, now, when Bolt starts running, the extension angle of the knee joint of his back leg increases from 130° to 175°.

This not only increases the length of the force arm from the hip joint of the hind leg to the sole of the foot, but also enables muscles such as the gluteus maximus to generate greater propulsive force when exerting force.

Step .

Optimize the pivot point position.

The fulcrum is critical to leverage.

Mills also made adjustments during the starting motion.

The point where the sole of Bolt's foot contacts the ground can be considered the fulcrum.

Then the three-dimensional migration trajectory of Bolt's center of pressure when he starts running will change.

When touching the ground vertically, the center of pressure quickly sinks to the rear edge of the sole and then moves forward.

Moving quickly forward horizontally from the front edge of the starting blocks, etc.

These actions are to optimize the fulcrum position.

This enables the lever system formed by various parts of the body to transmit force more efficiently and convert it into forward performance.

The seventh step.

Properly distribute joint torque.

Ultimately it all comes back to his three-joint torque power drive.

When Bolt started, his center of pressure formed an internal rotation angle of 8°-12° in the coronal plane.

Then the external rotation torque of the hip joint is used to offset the center of gravity shift caused by height.

Maintain the forward trunk tilt angle at 18°-20°.

Strengthen your starting joint torque.

The whole set of operations is completed.

Bolt has indeed made a lot of progress.

In particular, the technical feel has been greatly improved compared to before.

This made him a full ten meters.

Full of energy.

even.

Not much worse than Carter.

It can’t be much worse.

Bolt.

first 10 meters.

The horizontal migration distance of the pressure center is 1.85m.

The vertical amplitude is only 3cm.

The energy loss rate is 8.7%.

4.2% lower than regular players.

The loss is 5.5% compared to the normal level.

And you have to know that Bolt is over 1 meters tall.

Carter is only a little over 1 meters tall.

I don’t even know if his real height is 1 meters.

The height difference is more than 25 cm.

How could Bolt not fall behind Carter, who had re-realized the starting realm?

This is exactly what it means.

He actually has some ability.

Relying solely on physical talent.

No technical modifications or adjustments will be made.

It is absolutely impossible to achieve this level.

Even you can see.

Bolt's shot started.

Probably more than Powell.

Everything should be faster.

At least it's equal.

Go through this set of processes.

Bolt is extremely fast.

Ridiculously fast.

You can see it in his eyes.

His shot.

It's heading for a new world record.

Absolutely.

Sue.

Me today.

The most recent me.

Me in the past half month.

But they are all scalding hot.

Do you think you are the only one whose skills have improved?

I.

This year we have also made great technological progress.

Mr. Mills even praised me for my hard work.

Guy was not expecting that.

  Carter on his left had already started very strongly, but after all, Carter was Jamaica's starting machine.

This nickname already exists.

It makes sense.

The biggest problem is the person on my right.

This is the tallest guy.

He actually.

He actually ran a start that was not much inferior to Carter's.

This leaves Tyson Gay, who is in the middle of the two men.

rather embarrassing.

It is obvious that he has made a breakthrough compared to his previous self.

But under the double-team comparison of these two people.

Just show yourself.

The startup sucks.

Startup is slow.

Not popular at all.

Although in fact his starting ability this year is already at the level of many promising players.

result.

Because the opponents in this era are too terrifying.

And because of Su Shen's butterfly effect, everyone is making progress.

It can only be compared to make him look.

Not strong enough.

A little thin.

can.

Even Bolt, who upgraded his skill slots again.

in fact.

It did not shake the red figure on his right side at all.

Because just like Su Shen said before.

This game.

He is the one who has the advantage.

And than start.

That's exactly what I said.

No matter you are Bolt, Powell, Carter, or Terber.

No matter who you are, no matter what your name is.

In the startup world.

Especially now there is only one God.

That is.

Su Shen.

That is.

Yourself.
