The Su God of the Reopening of the Sports Arena

Chapter 2160: You are not the only one who has surpassed human limits

"Usain, you have great potential. I have always believed that you are the most perfect sprint specimen God has given to mankind."

"I think your cadence is close to perfect, and it's hard to change it with human power now, but I think your stride length..."

"You haven't reached your limit yet."

“You need to fix this.”

"Otherwise, if you want to completely break through your limits and go further, it may not be easy."

This is what Mills said to Bolt during winter training.

This also made Bolt truly realize his so-called ultimate talent——

What else needs to be filled?

There was no opponent who could threaten him before.

Then he just needs to make use of his existing talents.

It is enough to defeat all opponents.

Without the motivation and belief, I want to explore other things.

There is no way. Many people are like this. Even if you have super talents, you may not necessarily have super spiritual realm.

This is also the reason why many people feel regretful for some super talented people.

Because of their personalities.

So that they don't really realize their talents.

As an athlete, it is the time to realize talent.

It is always limited.

Very limited.

Bolt in this area is more like Chamberlain in basketball.

It wasn't Jordan.

It just means that in individual events, he would not be able to encounter a joint attack by his opponent's teammates.

When there is no rival who can match him, he can win alone.

It's that simple.

There has also not been any master of the same level who can be compared with him.

Under the pressure of level, he really only needs to fulfill the talent of Chamberlain.

There is no need to push yourself to reach the upper limit of your physical talent and surpass it like Jordan did.

The athletes themselves do not have this demand.

It is difficult for coaches to rely on their own whipping in this regard.

To make athletes aware.

After all, you reach a certain level.

You have to rely more on yourself.

Internal factors are more important.

can.

The arrival of Su Shen broke this balance.

At the 2011 Daegu World Championships, you might have said that you didn't play, so you gave the championship to Su Shen.

So what about London last year?

Bolt was defeated head-on.

Even the Olympic 100-meter record was surpassed.

Nominally it is shared.

But in reality, the percentile is even lower.

Everyone only mentions Su Shen.

He won't be mentioned as Bolt.

Under this pressure, Bolt finally began to mobilize his mental side.

Take the initiative to seek cooperation with Mills.

This was after he became famous.

It can be said that this is the first time.

Mills made a physical report on Bolt. Jamaica is not a place where savages gather, and there are still some instruments.

It’s just that it’s not the most advanced and cutting-edge one.

……

Bolt's muscle fiber types are ideally distributed, with a higher proportion of fast-twitch fibers. Fast-twitch fibers have the characteristics of fast contraction speed and great strength, and can generate strong explosive power in a short period of time, providing strong torque power for the joints.

……

From the perspective of joint structure, Bolt's joints have good flexibility and stability. Take the hip joint as an example. Its acetabulum is deep, and the femoral head and acetabulum fit closely, which can not only ensure the stability of the hip joint during large-scale movements, but also enable the hip joint to effectively transmit muscle power during sprinting and convert it into joint torque to propel the body forward.

……

Bolt's nervous system can efficiently recruit and activate muscle fibers. When sprinting, his brain can accurately control the frequency and intensity of nerve impulses, so that the relevant muscles contract in a specific order and time, and achieve precise control of joint torque. For example, during the mid-run phase, the nervous system will adjust the contraction strength of the leg muscles in a timely manner according to the body's movement state and speed requirements to maintain a stable and efficient joint torque output and maintain the body's high-speed movement.

……

He also has excellent proprioception, which allows him to accurately sense the position, direction and speed of joints, and then adjust muscle contraction through nervous system feedback to optimize the generation and transmission of joint torque. For example, during the sprint phase, Bolt can use his keen proprioception to fine-tune the angles of his leg joints and the way his muscles work, so that the joint torque power can be maximized and the speed can be maximized.

……

During the sprint, Bolt mainly relies on the phosphagen system and the glycolysis system for energy. The phosphagen system can quickly provide a large amount of energy in a very short time to meet the energy demand for the rapid increase in joint torque power during the start and acceleration phases. The glycolysis system continues to provide energy for muscle contraction in the subsequent mid-run and sprint phases to maintain a stable output of joint torque.

……

After long-term training, the number and function of mitochondria in Bolt's muscle cells have been optimized, enabling more efficient energy metabolism. At the same time, his body can better regulate acid-base balance, reduce muscle fatigue caused by lactic acid produced by glycolysis, ensure that muscles can continue to generate strong power throughout the sprint, and provide guarantee for the stability and improvement of joint torque power.

……

Mills read this report many times.

Finally, I figured out the possibility of breakthrough training from it.

When it comes to starting, Bolt pushes off the ground quickly and forcefully, exerting force on his hip, knee and ankle joints at the same time.

The extension torque of the hip joint swings the thigh backward, providing the initial momentum for the forward swing of the leg.

The extension torque of the knee joint straightens the calf, increasing the force and distance of the push-off.

The plantar flexion moment of the ankle pushes the body upward and forward, and so on.

The synergistic effect of these joint torques enables Bolt to obtain greater acceleration at the moment of starting and quickly get rid of the static state.

Then enter the run midway.

When running mid-distance, Bolt's joint torque power is mainly used to maintain and increase speed.

That is to say, when Bolt supports himself with one leg, his knee and ankle joints need to bear a large ground reaction force and convert it into power to propel the body forward through joint torque.

In addition, the rotation of Bolt's hip joint drives the swing of his thighs, always preparing for the next step of landing and stretching.

When the other leg is swinging in the air, the posture and speed of the leg are adjusted through the coordinated movement of the hip and knee joints to achieve a fast and efficient swing.

So how to make good use of joint torque power.

This became Mills's topic.

Mills should have thought about this issue from several aspects.

Although he had already thought about this kind of thing.

But to get started thoroughly, a more detailed analysis is still needed.

For example, Bolt's muscle fiber types are ideally distributed, with a higher proportion of fast-twitch fibers. Fast-twitch fibers have the characteristics of fast contraction speed and great strength, and can generate strong explosive power in a short period of time, providing strong torque power for the joints.

Then, at the moment of starting, fast muscle fibers are rapidly recruited, causing the leg muscles to contract rapidly. Through the coordinated action of the hip, knee and ankle joints, huge joint torque is generated, pushing the body forward and accelerating.

From the perspective of joint structure, Bolt's joints have good flexibility and stability.

Taking the hip joint as an example, its acetabulum is deep.

If it is deeper, the femoral head and acetabulum can fit closely, which can not only ensure the stability of the hip joint during large-scale movements, but also enable the hip joint to effectively transmit muscle strength during sprinting and convert it into joint torque to propel the body forward.

Then at the moment of starting, Bolt can rely on the powerful contraction of his leg muscles to generate joint torque.

Then you can start faster and run faster along the way.

What about the extreme speed zone?

Is it possible?

Better and faster.

of course……

can.

Mills began to think about how to allow Bolt to maintain efficient joint torque power output during the mid-run phase.

For example, at the hip joint, the gluteus maximus and hamstring muscles contract strongly, forming a stretching torque that causes the thigh to swing backward quickly, providing strong support for pushing off the ground.

For example, the quadriceps and hamstrings around the knee joint work together. The quadriceps contract and straighten the knee joint, generating a knee extension torque, increasing the force and distance of pushing off the ground, while the hamstrings help stabilize the knee joint and participate in the backward swing of the thigh.

For example, the plantar flexor muscles of the ankle joint exert force to generate a plantar flexion torque, pushing the body upward and forward like a spring.

These joint torques are output explosively in a very short time. According to the impulse theorem in physics, impulse is equal to the product of force and action time. The huge joint torque generated instantly makes the body obtain huge impulse, thereby obtaining a greater acceleration.

And then start entering the strongest speed zone?

How to liberate at high speed.

Better play to Bolt's advantages!

What is Bolt's greatest strength?

One of them is of course -

Super fast!

Unmatched super speed!

The only super monster in human history with a speed of over 45.

So what can we do to make it perform better?

Mills has been thinking about this question.

Just this year.

I finally had the chance to use it.

But this problem.

He has been thinking about it for many years.

"Usain, when you are running, when one leg is supporting the ground, the knee joint needs to bear the ground reaction force that is several times the body weight. At this time, the joint torque generated by the contraction of the knee extensor muscles not only supports the body weight, but also converts the ground reaction force into the power to propel the body forward."

"At this time, you need to pay attention to the continuous rotation of the hip joint to drive the swing of the thigh."

"The coordinated contraction of the hip abductor and adductor muscles maintains the stability and correct trajectory of the thigh during the swing process, ensuring the effective transmission of the hip joint torque."

Mills said this because he discovered under the high-speed camera——

When Bolt is running, the joint torque power of his supporting leg knee can reach [X] watts at the moment of each step touching the ground.

The hip joint torque power is maintained at around [X] watts. This stable and efficient joint torque power output is the key to his high-speed running.

What is x?

Only Mills himself knows.

He won't tell anyone.

This is also a valuable personal experience.

Bolt.

This is what we are doing now.

Utilize the torque power that mills give to re-engineered joints.

To break your own speed limit.

Extremely fast.

limit.

We are almost at the speed zone.

Bolt has started to exercise his body as Mills said during winter training.

He doesn't have the same brains as Su Shen.

Can be understood clearly.

but……

His physical instincts for sprinting.

It is a talent that surpasses ordinary people.

Can do what Mills wants him to do.

even though.

The principle of this thing itself.

He didn't understand at all.

Not even a clue.

It doesn't matter.

This.

It's talent.

One of those super talents that most people don't have.

Fifty meters.

Bolt is liberated at high speed.

Bang bang bang.

During landing and swinging, the leg joints precisely control the torque generated by muscle contraction to keep the body's center of gravity in stable translation, reducing energy loss in the vertical direction and unnecessary shaking.

Why do this?

Mills knew that explaining the principle to him would be difficult for Bolt's mind.

Then.

He said to Bolt in the simplest words:

By doing so, the efficient output of joint torque power can be utilized to ensure the optimal combination of stride length and stride frequency.

Bolt doesn't need to understand the rest of the deep principles and basic logic.

That's all he needs to know.

Use this joint torque power.

To adjust your cadence and stride length.

advanced optimization.

Allow him to further push the upper limit of his speed.

Of course you understand that.

Bolt's top speed.

In a sense, it represents the extreme speed of human beings.

It’s like Su Shen’s start and future.

It also represents the start and future of mankind.

Mills asked him to do it.

It represents humanity in reaching new speed heights.

Bang bang bang.

After Bolt was released at high speed, his speed increased immediately. He rationally adjusted the torque of his knee joints during the extension and buffering stages, so that each push off the ground could convert more energy into kinetic energy for the body to move forward.

While swinging your legs quickly...

It also benefited from Mills' coordination of the torque of his hip and knee joints during winter training to increase his stride.

Continue to maintain a high cadence.

Thereby continuously improving and maintaining the top speed.

55 m.

Bolt's ankle plantar flexion torque power during sprinting is greatly improved.

Make pushing off the ground more powerful.

The stride length is further increased.

60 m.

The coordination between Bolt's body joints is closer. Through the fine regulation of the nervous system, the energy loss in the transmission process of joint torque is visibly reduced, and more of it is used to propel the body forward quickly.

His stride is increasing.

Even if it's just a little bit.

But for someone at his level, any point.

Accumulate.

They are all huge improvements.

In each step, when Bolt's supporting leg touches the ground, his knee and ankle joints are subjected to huge ground reaction forces, which are converted into power to propel the body forward through the contraction of the muscles around the joints to generate reverse joint torque.

In each step, Bolt's hip joint continues to rotate, and through the coordinated contraction of the abductor and adductor muscles, the thigh swings to prepare for the next step of landing and extension.

In each step, Bolt's arm swing action generates torque through the movement of the shoulder joint, which not only helps to maintain body balance, but also affects the leg movement through the transfer of the body's rotational inertia, allowing the leg joints to exert torque power more efficiently.

……

Here.

Bolt's speed suddenly increased.

Is this the effort that Su Shen just came up with?

Is this the level?

Such thoughts.

In the next half second.

It has been completely extinguished.

Because of the tall figure that was quite a distance away from him just now.

Just at this moment.

It's like being overclocked.

Start approaching quickly.

Shrinking rapidly.

A time that Bolt fans have been waiting for.

finally come.

Bolt is here.

I'm afraid I've already exceeded my speed limit.

It’s also human.

Speed ​​limit.
