The Su God of the Reopening of the Sports Arena

Chapter 2154 I usually don't care how fast the other party is when I start

When both Carter and Bolt went one step further.

There are people who are qualified to say this.

There is only one left.

That was the only red light on the field.

Su Shen.

At the beginning of this season, he completed the three-in-one startup acceleration integration in a hard fight with Old Bao.

In other words, not only when Su Shen is running, his pelvis can also exhibit active and positive movement under the sophisticated control of the central nervous system.

During the acceleration phase of the stance, the pelvis internally rotates about the vertical axis of the hip joint on the stance leg.

The central nervous system uses neuronal signal transmission to precisely regulate the contraction and relaxation of the muscles around the pelvis. Subsequently, the gluteus maximus, gluteus medius, iliopsoas, etc. are mobilized, which play different roles at different time points and work together to promote the internal rotation of the pelvis.

The pelvis rotates about the vertical axis of the hip joint on the side of the stance leg - a movement called internal rotation.

This is the key point that Lao Bao conquered.

On this basis, Su Shen added what happens if the pelvis is slightly tilted or shifted in a certain step.

The proprioceptors immediately transmit this information to the central nervous system.

This enables it to send adjustment signals in time to ensure that the pelvis remains in the correct position.

In this way, the central nervous system can more accurately control the accuracy of the pelvis during the startup acceleration phase.

This is not over yet, there is one more step.

He also added running space orientation.

That is, when running, the surrounding scenery observed by the eyes allows the central nervous system to determine the direction and route of running, and thus adjust the direction of movement of the pelvis accordingly.

While increasing the body's speed, vision prompts the central nervous system to adjust the angle of the pelvis to adapt to the curvature of the curve and maintain the body's balance and stability.

Very awesome!

Not many people know the term "directional training" in space running, let alone the specific training model and methods.

This 3-in-1 combo punches down.

In other words, the human pelvis also performs internal rotation around the vertical axis of the fulcrum under the control of the central nervous system during running.

Su Shen was demonstrating his indoor game at the beginning of this season.

It has completely surpassed everyone.

Including Old Bao, who thought he had made a breakthrough this year.

Everyone who saw this found it hard to believe.

Powell even wonders if this is the limit direction and best model for human beings to initiate?

He can only do step 1 now. He can't do steps 2 and 3 well. He doesn't even know the direction of training.

In his opinion, something that transcends cognition and time is a bit like magic.

It’s a bit like the ancients who only wanted to go to heaven but didn’t know how to get there.

If you see someone going up there, they will definitely exclaim that it is a deity.

Can……

Is this enough?

Maybe in Old Bow, or even in the rest of the pros.

For example, in the eyes of professional teams like Francis.

This is also the limit of human beings.

It even pointed out the direction for their future.

Can……

This problem is not facing all of humanity now.

Not facing the rest of the professional teams and professionals in the world.

this problem.

Now I'm facing only one person.

Facing Su Shen himself.

Ask yourself.

This.

Is that enough?

of course.

not enough!

This is because Su Shen knows the direction to continue strengthening.

So, it’s a regret that I didn’t do it in my previous life.

It’s a pity that I can’t do the experiment myself to explore the direction.

There is no way I can let it go in this lifetime.

just now.

Su Shen even used these "experiments" on himself.

Getting more and more excited.

It's even a kind of fanaticism similar to that of scientific researchers.

Don't forget it.

He is a two-life athlete.

But he is still... a scientific researcher in two lifetimes.

In both the previous life and this life, I was the manager of Su Shen Speed ​​Laboratory.

If track racing arouses his athletic instincts.

Then.

Research experiment.

It is to arouse his scientific research instinct.

no way.

It's just so irresistible!

Perhaps everyone thinks that the bent-arm start has reached a level that is one level ahead of the world and is advanced enough.

But Su Shen wanted to say it.

It’s not enough, we can also strive for perfection.

It can also be faster.

There may also be newer versions.

For example, his current bent-arm start 2.0.

It is the biomechanical reconstruction principle of the 100-meter bent-arm start technique!

The first step is the optimal configuration of the lever system.

The naturally built back muscles form an overall state that is almost perfectly stretched out and fits the upper arms.

This is just the beginning.

This is not the end of the improvements in articulated arm technology.

The modified parts also include the deltoid muscle.

Why the deltoid?

This is because the anterior deltoid is the main driving muscle of shoulder flexion. When the arms are bent and the start is running, the force generated by its contraction is an important source of power for the arms and the whole body to move forward.

When the anterior deltoid muscle contracts, a force is generated with the shoulder joint as the center, which causes the arm to swing forward. The direction and magnitude of this force are crucial to the initial velocity and acceleration of the start.

According to scientific calculations, by shortening the length of the resistance arm (forearm length × sinθ), when θ=110°, sinθ≈0.93, which reduces the torque by about 180% compared to the original arm state (θ=0°, sinθ=42)!

Then, use the isometric contraction of the triceps to lock the elbow joint angle, providing a stable foundation for the contraction of the anterior deltoid.

During an isometric contraction, the muscle does not change length, but it produces enough tension to maintain the joint angle.

So it can be said that when the anterior deltoid muscle contracts, the elbow joint will not change its angle arbitrarily due to the action of force, ensuring that the force can be effectively transmitted to the contact point of the palm.

Thus.

You can activate the shoulder joint to extend the power arm!

The human upper limb is a kinetic chain composed of multiple joints and muscles. In the bent-arm start, the shoulder joint, elbow joint, and wrist joint work together. The force generated by the contraction of the anterior deltoid muscle is transmitted to the palm along the forearm through the locked elbow joint. Because the triceps maintain the stability of the elbow joint, the force loss during the transmission process is small, and it can be more efficiently transmitted from the shoulder joint to the palm, and then act on the ground.

Then when the power arm of the shoulder joint is extended, the force generated by the contraction of the anterior deltoid muscle is transmitted to the palm through the longer power arm, so that the palm can act on the ground with greater force and a more reasonable angle, thereby obtaining a greater ground reaction force and pushing the body forward.

This involves the integration of the upper limb kinetic chain and its relationship to ground reaction forces.

If you don't think of the knowledge embedding here, you will never be able to grasp the key points, let alone understand the training mode and system.

This theory requires the combined efforts of many scientific teams.

Now here with Su Shen.

It can be broken by raising your hand.

Easy integration.

This is the true strength of the scientific reopener.

He knows all the right paths, and he knows all the wrong ways to avoid them.

He alone can integrate theories that require cross-validation by many scientific teams from different systems.

It seems that Su Shen has not brought any golden fingers or plug-ins when he restarted.

But in fact.

Someone who is truly knowledgeable and has a reserve of intellectual knowledge.

Straight across.

The knowledge system structure over the years.

Always the correct cognitive direction.

It’s the biggest hang.

The 110° arm bending technique used by Su Shen here transfers the fulcrum to the elbow joint.

It is to form...a compound lever system!

During the contraction of the anterior deltoid, the chemical energy stored in the muscle is converted into mechanical energy. By extending the power arm, the mechanical energy generated by the muscle contraction can be more effectively transferred to the overall movement of the body.

Extending the power arm is equivalent to increasing the distance over which the force acts. According to the principle of work W = Fs (work = force × distance), when the force is constant, as the distance of action increases, the work done by the force increases, thereby enabling the body to obtain greater kinetic energy and increasing the starting speed.

This involves muscle energy and conversion.

Then the 100-meter start pre-tension conduction pathway is reshaped.

Reconstruct the composition of the "abdominal pressure cylinder" mechanism.

The transverse abdominal muscle is the deepest muscle of the abdominal wall, and its muscle fibers surround the abdomen. When the transverse abdominal muscle contracts, it exerts pressure on the contents of the abdominal cavity from the deep abdomen like a corset. It is an important part of the "abdominal pressure cylinder" mechanism, which can stabilize the abdominal cavity and provide a stable foundation for other movements.

The multifidus muscle is located on both sides of the spine and consists of multiple muscle bundles that extend from the sacrum to the cervical spine. Its main function is to assist the extension, lateral flexion and rotation of the spine, and to perform fine stability control on the spinal segments. In the "abdominal pressure cylinder" mechanism, the contraction of the multifidus muscles can enhance the support and stability of the spine from the back, and work together with the transverse abdominal muscles to maintain the integrity of the "abdominal pressure cylinder" from both the front and back directions. When the transverse abdominal muscles and multifidus muscles contract at the same time, they compress the organs in the abdominal cavity and increase the intra-abdominal pressure. This increased abdominal pressure is like forming a pressure-filled "cylinder" in the abdominal cavity, providing additional rigid support for the trunk.

This rigidity enables the torso to better maintain its shape and stability when subjected to external forces, reducing unnecessary deformation and energy loss.

The pressure generated by the "abdominal pressure cylinder" is evenly distributed in the abdominal cavity and transmitted to the entire trunk through the muscle fascia structure of the abdomen and back. In this way, the force generated by the extension of the lower limbs can be transmitted upward more effectively along this rigid trunk without the dispersion or deviation of force due to the softness or instability of the trunk.

This utilizes the transverse abdominal muscle and multifidus muscle to generate and maintain pressure and disperse and transmit force.

This is equivalent to letting——

The bent-arm state forms a prestressed bundle in the brachioradialis, flexor digitorum superficialis, etc., which transmits the scapula extension force directly to the starting blocks, reducing energy loss and force dispersion and transmission.

Cooperate with your own local talent of back muscles.

Combined.

Then the upper limb stiffness is readjusted.

It's finished.

But sprinting is a more lower-limbs athlete.

No matter how good your upper limbs are, you can't move them.

So, we come to the second question - using core muscle coupling to reconstruct the deep logic of axial transmission of lower limb extension force.

That is, after doing all of the above.

When starting a race, the extension force of the lower limbs needs to be transmitted to the upper limbs and the whole body through the torso to push the body forward.

The trunk rigidity established by the "abdominal pressure cylinder" mechanism makes the force transmission path more direct and smooth, reducing the loss and direction change of force during the transmission process.

The extension force of the lower limbs can be transmitted upward along the central axis of the body more efficiently, providing strong power support for the body's rapid start.

At the same time, the transverse abdominal muscle and multifidus muscle work together with other core muscles such as the rectus abdominis and oblique abdominal muscles to maintain the overall stability of the body.

When the lower limbs are extended, these muscles cooperate with each other to stabilize the torso through the "abdominal pressure cylinder" mechanism, ensuring that the body maintains the correct posture and balance during the starting process, so that the lower limb extension force can be fully converted into forward acceleration of the body, improving the efficiency and speed of the start.

In addition to the transverse abdominal muscle and multifidus muscle, the rectus abdominis and oblique abdominal muscles are also used. Contracting the rectus abdominis can increase the pressure on the front of the abdomen, and the oblique abdominal muscles can help generate rotation and lateral flexion forces, working together with the transverse abdominal muscle and multifidus muscle.

Stabilizing the trunk from multiple directions makes the "abdominal pressure cylinder" more stable, providing a solid foundation for the transmission of lower limb extension force.

The muscles are then connected to each other through the fascia to form a myofascial chain.

In the "abdominal pressure cylinder" mechanism, the transverse abdominal muscle, multifidus muscle and the fascia of the surrounding muscles are connected to form a force transmission network.

The extension force of the lower limbs can be transmitted to the core muscles through the fascia, and then the fascia of the core muscles transmits the force upward to the upper limbs and other parts, realizing the integration and transmission of whole body strength.

In this case.

The original bent-arm start of 1.0 makes the trunk lack rigidity, and the extension force of the lower limbs will cause the trunk to produce unnecessary movements such as bending and twisting, leading to problems such as force dispersion and loss.

Will be improved.

Su Shen's bent-arm start 2.0 here uses a rigid torso established by the "abdominal pressure cylinder" mechanism, which can transmit the lower limb extension force upward along the central axis of the body, reduce the loss of force during the transmission process, and improve energy utilization efficiency, so that more energy can be used to push the body forward to start and accelerate.

To put it simply -

New startup mode.

Start the decentralized mode of force.

further offset.

further reduced.

So……

Want to be unhappy.

They are all difficult.

Su Shen took one step at a time.

And he did exactly the same thing every season and every game since the restart.

He has been doing this for the past 10 years.

Every game has a clear purpose.

Each game has clear mission objectives and experimental subjects.

Regardless of success or failure.

The goal is extremely clear.

Never waste a game.

After all, these competitions were carefully selected by him through his memory.

Every game has its own considerations.

It must not be wasted easily.

boom!

This.

That's why Su Shen saw Carter and Bolt.

When their startups are strengthened.

They have all further broken through their own limits.

Yet it is still as steady as a rock.

Just like Jiang Taigong fishing.

Sitting there motionless.

The reason why I am not affected by them at all.

Because.

To paraphrase a famous saying from a business gentleman:

Usually when I start up.

Neither cares how fast the other starts.

Don't care whether the opponent's start has a breakthrough or not.

Because anyway.

Not as fast as me.

Voila.

The principle is not difficult.

It's that simple.

When Randy heard the report on his improvements to the crank start—

I guess they are no different from the spectators.

Because of the integration of so many knowledge systems and amounts of knowledge.

It had long exceeded what he could bear.

The key is that these improvements are not the same as those of those who cheat and add points.

Just write the answers.

You can't give a professional explanation.

There is no way to truly conquer professionals spiritually and mentally.

Want to conquer the professional bosses.

It's even more idiotic.

But Su Shen.

Every time I can use a complete data chain and a complete theoretical chain to write the analytical process of the answer clearly.

It's hard not to be shocked.

This.

This is the real means of rebirth to conquer professional bosses.

Because these big guys never only care about the results.

Problem-solving methods, steps and thinking patterns.

That's what they really want to see.

It is also true science that can be broken down.

Even copied stuff.

One of the meanings of science.

The purpose is to make things not unique.

It can be produced in larger quantities or even in batches.

Analysis of principle process model.

This is the core that can be learned, absorbed, imitated and innovated by countless people.

Su Shen.

This wave of improvements.

After the shock.

No one will be dissatisfied.

Is it simply because of his grades?

No.

It’s because he has detailed steps to solve the problem.

Then.

I improve.

I broke through.

I become stronger.

is not it……

This is how it should be.

This.

a match.

Su Shen prepared for a long time.

Definitely ready...

Come on, a big wave!!!
