The Su God of the Reopening of the Sports Arena

Chapter 2496 A New Fascial Line Awakening! This is the strongest step humanity can take to activate its potential.

In the field of sports research.

Compared to muscle movement research that has been developed for nearly a century.

New fields are the key to taking things a step further.

This is something others may not know, but Su Shen knows it better than anyone else.

So when we were on Ersha Island.

He has been developing his own fascial chain.

That's right, fascia is a new system in the future of kinesiology, a brand-new energy supply system in addition to the well-known muscles, bones, and ligaments.

That's what he and Randy were talking about.

Further modifications are needed.

Just when everyone thought he had reached the end.

Only he knew that he didn't have it yet.

To fully master all 12 fascial chains in the human body and integrate them into one's own movement system is, frankly, a bit of a stretch.

So far, all Su Shen has accomplished is front-table chaining and back-table chaining.

They hadn't even fully mastered the spiral chain.

But to go further, he knew he needed to remove the arm chain.

We need to secure at least a portion of it.

Moreover, arm training, specifically the arm line, includes four fascial chains.

He just needs to do one more thing better.

Take one down.

This will greatly benefit you.

after all.

His starting line was different from others.

Start with bent arms.

The capacity that the arm originally could bear.

It is much larger than the others.

Although he made some improvements and used more back energy.

But this is clearly not enough; the application and development of deep energy is not well done.

Want to go further.

This aspect is absolutely essential.

and so.

The core of the twelve-fascial chain theory is "fascial continuity" and "overall force network".

It enables the transmission of power and integration of energy throughout the body by connecting the fascia of the human body through 12 interconnected chains.

The arm line, as a key hub connecting the upper limbs with the trunk and lower limbs, is not simply a “two-chain structure”.

Instead, it consists of four independent yet coordinated chains: the anterior superficial line, the anterior deep line, the posterior superficial line, and the posterior deep line.

These four arm lines are centered on the humerus and are distributed in a "double-layered, bidirectional" pattern, with the two anterior chains dominating upper limb flexion, adduction, and pronation.

The two chains on the back dominate extension, abduction and supination, together forming a "tension balance system". The deformation and tension regulation of its elastic fibers directly determine the energy efficiency of upper limb force, which is highly consistent with the starting requirements of bent-arm start.

Therefore, this problem must be solved in order to advance further in this area.

This was completely beyond Randy and his group's knowledge.

After all, no one in this era has ever studied this thing. Su Shen is the founder of this theory.

He is everything.

Therefore, they had to listen to him in all aspects, and even what he said they had to go back and carefully study and digest.

Otherwise, they wouldn't understand what Su Shen was talking about at all.

This is because they already possess a very strong foundation of sports knowledge. Furthermore, they received hands-on guidance and assistance from Su Shen in overcoming difficulties. Otherwise, it would be impossible to quickly absorb this basic knowledge.

Even for them, it's difficult.

The arm chain consists of four strands—

Anterior superficial line of the arm.

Anatomical structure: It originates from the manubrium of the sternum, the medial third of the clavicle, the sternal origin of the pectoralis major muscle, the fascia of the external oblique muscle, extends along the superficial layer of the anterior side of the humerus, passes through the biceps brachii and brachialis muscles, descends through the flexor carpi radialis, palmaris longus and flexor carpi ulnaris muscles, connects to the palmar aponeurosis and the common tendon of the flexor digitors, and finally terminates on the palmar side of the distal phalanx.

Its functional positioning is: a shallow tension conduction dominant chain, and its core function is "rapid tension storage and explosive release".

In the bent-arm posture, the chain transmits the tension generated by elbow flexion to the core through the connection between the pectoralis major muscle and the anterior trunk fascia. At the same time, its surface elastic fibers are rapidly stretched when the elbow is flexed, forming a significant elastic potential energy storage effect.

At startup, a large amount of kinetic energy is released through rapid muscle contraction and passive fascial retraction.

Anterior deep line of the arm.

Anatomically, it originates from the subclavian, pectoralis minor, and coracoid process of the scapula, extends along the deep layer of the anterior humerus, passes through the deep layer of the biceps brachii tendon, brachioradialis, and pronator teres, descends through the extensor carpi radialis brevis, flexor pollicis longus, and flexor digitorum profundus, connects with the carpal tunnel fascia and the connective tissue around the deep palmar arch, and finally terminates on the palmar side of the proximal phalanx.

Functional Positioning: A deep, stable, and precise tension control chain, with its core function being the "refined storage and optimized conduction of elastic potential energy." This chain runs deep within the muscles and is closely connected to the joint capsule and ligaments. When the arm is bent, it forms a "rigid tension fulcrum" through the fixing action of the pectoralis minor muscle and scapula, preventing energy leakage caused by excessive tension in the surface chain. At the same time, its deep elastic fibers can store "slow-release elastic potential energy," complementing the "fast release" of the surface chain.

In addition, there are four lines: the superficial line and the deep line on the back of the arm.

It forms a complete arm line.

The two new fascial lines that Su Shen conquered are located inside the arm chain.

These are also known as the anterior superficial line and the anterior deep line of the arm.

Why choose these two points first?
This is because the core biomechanical requirements of the flexed arm start are determined by the functional priority of the fascia lines.

The key characteristics and core requirements of the bent-arm start are—

The essence of the sprint start with bent arms is the energy conversion process of "completing the storage of elastic potential energy, explosive release, and horizontal propulsion in a very short time".

That is--

Preparatory stage (pre-activation period): It is necessary to quickly build a high-tension stable state in a bent elbow posture to maximize the storage of elastic potential energy and shorten the force exertion delay time.

Initiation phase (burst phase): The stored elastic potential energy needs to be efficiently converted into upper limb swing kinetic energy and horizontal propulsion force, forming a "push-swing coupling" with the lower limb push-off force to increase the starting acceleration.

Transition phase (connection period): It is necessary to precisely control the changes in tension to achieve a smooth transition from the start of the bent arm to the mid-run swing, and avoid energy leakage.

The core requirements of these three stages can be summarized as "three fasts and three highs": fast energy storage, fast release, and fast transmission.

In other words, it has high tension, high conversion, and high stability.

The functional priority of fascia threads is directly determined by whether they can meet this core requirement.

The functional characteristics of the two lines on the front are perfectly matched with the requirements.

Therefore, it became the core target of Su Shen's technical breakthrough.

Functional prioritization is not a subjective choice, but a quantitative assessment based on the following four biomechanical standards:
That is, 1. Energy contribution weight: the proportion of the fascia line in the generation of elastic potential energy and propulsion force during the initiation phase.

2. Response speed: The time delay from pre-activation to energy release, i.e. the rate of tension build-up and elastic recovery.

3. Controllability: The ease with which precise tension control can be achieved through neuromuscular regulation.

4. Synergistic dependence: Whether other fascial threads are needed to perform the core function, and the strength of its independent function.

Based on Su Shen's own bent-arm start motion, high-speed video and electromyography tests, and dynamic three-dimensional unit analysis and quantification, the functional performance of the four arm lines can be observed...

The data clearly show that the anterior superficial line and the anterior deep line of the arm are significantly better than the two posterior lines in terms of energy contribution, response speed, and controllability.

It has lower collaborative dependency.

It possesses the conditions to independently become the core of technological breakthroughs.

Therefore, it became the primary target for improvement in the bent-arm start.

In particular, this collaborative dependency is lower.

With this, there's no need for more systems or technologies to be combined and modified.

The time cost, energy cost, and difficulty cost will all be significantly reduced.

The higher the synergy dependency, the more necessary it is to mobilize other technologies to advance and adjust together in order to achieve the desired effect.

Therefore, at this stage, we are facing the upcoming Beijing Olympics.

The first choice should definitely be the two forearm lines, which have lower synergy dependence.

Why choose this one?
Simply put—

The elastic fibers of the anterior superficial line of the arm are mainly composed of elastin. The interwoven structure of collagen and elastin exhibits the characteristics of "high elasticity and low viscosity", which determines its core advantage in energy conversion.

For example, in the energy storage stage.

During elbow flexion pre-activation, the elastic fibers stretch rapidly, with a deformation speed of 0.8-1.0 m/s and an energy storage time of only 0.2-0.3 seconds, perfectly matching the time requirements of the starting preparation phase.

For example, the release phase.

At the moment of activation, the elastic fibers retract at a speed of 1.2-1.5 m/s, which is much faster than the active contraction speed of the muscle, forming a superposition effect of "passive release of fascia + active contraction of muscle", with an energy release power of 320 W/kg, which is 57% higher than simple muscle contraction.

For example, the direction of energy.

The direction of the released kinetic energy is completely consistent with the direction of the upper limb swing, and the horizontal component accounts for 85%.

It can be directly converted into propulsion, avoiding energy waste.

Even the most basic electromyography (EMG) test data can be displayed.

At the moment of initiation of arm flexion, the peak electromyographic activity of the relevant muscle groups on the anterior surface of the arm reached 89.6 μV, which was 41.2% higher than that on the posterior surface of the arm.

Furthermore, the peak time is 12ms earlier.

This proves that it is the "primary driving force" in the initial stage.

Once you understand this, you'll understand why Su Shen prioritized completing these two lines of the forearm chain.

Let's go back to the combination with the bent-arm start.

As we all know, in traditional straight-arm starts, the frontal surface of the arm is in a relaxed state, relying solely on the passive stretching and energy storage through the push-off of the lower limbs, resulting in low energy storage efficiency.

The bent-arm posture represents three major qualitative changes.

First, from "passive" to "active": the elbow flexion movement actively stretches the fascial chain through muscle pre-contraction, changing the energy storage mode from "passively receiving tension" to "actively building tension", increasing the total energy storage by 78%;

The second is from "local" to "whole": bending the arm stretches the entire anterior surface line chain, rather than simply contracting the biceps brachii, expanding the energy storage range to the trunk and hands, forming a coordinated energy storage throughout the body;

Third, from "low tension" to "high tension": When bending the arm, the tension value of the anterior surface line reaches 18-22N, which is in the "optimal elasticity range" of the fascia, ensuring maximum energy storage while avoiding fascial damage.

Combining these three points.

This reveals that the deep line of the arm is the center of "precise control and efficient transmission" for the bent-arm start.

It can provide deep stabilization.

It provides rigid support for explosive energy storage.

Because the deep anterior line of the arm, the deep layer of the subclavian muscle-pectoralis minor-biceps brachii tendon-pronator teres-flexor digitorum profundus, is located in the deep layer of the upper limb and is closely intertwined with the joint capsule and ligaments. Its core function is to construct a "rigid tension fulcrum".

That's what Su Shen did today.

first step.

Contraction of the pectoralis minor muscle fixes the scapula to the rib cage.

Avoid forward shoulder tilting caused by high tension in the anterior surface of the arm.

Make sure the direction of the biceps brachii stretch is consistent with the axis of the humerus.

Reduce lateral energy leakage.

Energy storage efficiency is improved.

The second step.

The connection between the subclavian muscle and the shoulder joint capsule.

Enhance shoulder joint stability.

When the arm is bent, the adduction torque of the shoulder joint increases.

To avoid tension loss caused by joint wobbling during startup.

third step.

Synergy between the pronator teres muscle and the carpal tunnel fascia.

Keep your wrist in a neutral position.

Ensure the continuity of tension between the palmar aponeurosis and the flexor carpi radialis.

This forms a closed loop of tension transmission from the wrist joint to the elbow joint.

According to that logic, wouldn't it be simpler to just conquer one?

It's easier and has a higher success rate.

There's also more time available.

that is because.

If deep stabilization of the anterior deep line of the arm is lacking.

The high-tensile energy storage of the forearm surface line will face...

Risk of “tension leakage”.

Energy conversion efficiency will decrease by more than 35%.

This is also the core reason why the two front lines must be attacked simultaneously.

Simply put.

The front panel is responsible for "energy storage and release".

The front-deep line is responsible for "stabilization-transmission".

The two form the core system of "power + regulation".

It's important to understand that the starting process of a flexed arm start is not a "single tension release".

Instead, it is "dynamic tension control".

From the high tension of the preparatory posture to the explosive release at the moment of initiation, and then to the tension decay in the transition phase, precise tension gradient changes are required.

The deep anterior arm line achieves this regulation through the following mechanism.

The first is tension perception.

Proprioceptors distributed in the deep fascia.

Muscle spindles, Golgi tendon organs.

The density reaches 12 particles/cm.

It is 2.5 times that of the superficial fascia.

It can sense changes in tension in real time and send feedback to the central nervous system.

Then it is released in stages.

The elastic fibers of the deep anterior line of the arm account for 60% of collagen, and have both elastic deformation and viscoelastic deformation characteristics. They can release some energy through viscoelastic delay, so that the explosive energy of the anterior superficial line and the slow-release energy of the deep anterior line form a "double peak superposition".

Extends power output time by 0.04-0.06 seconds.

At this time, if there is an upper limb swing deviation during the start, the pronator teres and flexor digitorum profundus muscles of the anterior deep line can contract rapidly.

Adjust the angle of the wrist and elbow joints.

Correct the direction of tension.

Ensure that the propulsion force is always in the horizontal direction.

This refined "perception-regulation-correction" function is irreplaceable by the two lines on the other side.

Because the posterior line lacks sufficient proprioceptor density, it is difficult to achieve millisecond-level tension regulation.

Of course, this refers to simply tackling the latter two lines.

If all four are combined.

That would be the best, of course.

After all, when Nuwa created humans...

It's just that these four lines were combined together.

However, mastering all four at once is too difficult.

How to make choices is a question that everyone has to face.

Su Shen is here.

I always get full marks.

After getting these two threads of the arm chain sorted out.

Indirect bent-arm start crosses energy transfer.

This transforms into an energy loop that connects the upper limbs, core, and lower limbs.

When Suarez started with his arms bent, he was already conducting upward transmission.

What is upward conduction?
The tension generated by the fingers gripping the ground before the start of the race passes through the deep layers of the flexor digitorum profundus, pronator teres, and biceps brachii tendons.

It is transmitted to the pectoralis minor, activates the deep anterior core line, and improves core stability by 25%.

It provides rigid support for the lower limbs to push off the ground.

Then proceed with the downward transmission.

The force of the lower limbs pushing off the ground is transmitted through the deep anterior core line to the pectoralis minor muscle, and then through the deep anterior arm line to the wrist joint.

It increases the pressure on the fingers to grip the ground by 30%.

Further enhance front-end energy storage.

Next, cross-chain collaboration will be adopted.

The anterior deep line of the arm, the anterior deep line of the core, the anterior superficial line of the lower limb, and the fascia of the quadriceps femoris-iliopsoas muscle are continuous.

This reduces the energy conduction loss rate between the upper limbs, core, and lower limbs from 28% to 12%!

This cross-linkage transmission function makes the two anterior lines the core of whole-body energy integration, rather than simply an upper limb force chain.

In other words, Su Shen is utilizing the functional positioning of the anterior superficial line and the anterior deep line of the arm as "active energy storage - active release - active regulation".

The goal is to take the lead in energy generation and transmission during the entire startup phase.

Active energy storage.

Ready.

Tension is actively built through muscle pre-contraction, rather than passively stretching by relying on external forces.

Release the initiative.

Ready.

The muscles contract rapidly at the moment of initiation.

Actively triggers the elastic recoil of the fascia.

Instead of passively responding to the lower limbs pushing off the ground.

Proactive regulation.

The allocation is complete.

By precisely adjusting the tension and release timing through neuromuscular control, it can adapt to different initiation requirements.

This is a proactive functional positioning.

This makes the front flank the "energy core" of the starting phase.

Its functionality directly determines the upper limit of the startup acceleration.

After everything was done, Su Shen felt that several areas could be optimized.

Reduce startup time.

From "energy storage delay" to "instantaneous burst".

Increase the total amount of elastic potential energy.

Break through the bottleneck of starting power.

Optimize the coordination of pedaling and swinging.

From "separate efforts" to "coupling and explosive growth".

These are the changes Su Shen made before the match.

Do you think only Bolt has completed the optimization and upgrade?

Did Bolt make use of these few months?
Has Su Shen really given up?
Now he'll prove it to you.

When he took it down. Randy and Ralph Mann.

Just how surprised were they?

Sue.

Come on, start it up and show them.

Let the whole world see.

The so-called limit of your life.

what.

wrong.

This is what is known as the limit of human capability.

How did you do it step by step?

Break it with your own hands.

How do you cope every time you think you've reached your limit?

Entering a new limit.

Come on, Sue.

Let's show it off.

Randy stood with his hands in his pockets, watching from a short distance away on the other side of the starting line.

As a sprinter's coach, you don't need to do anything during the competition like a football or basketball coach.

If there's anything else that needs to be done during the game.

Then the coach would be guilty of dereliction of duty.

Because it's what needs to be done.

The moment he stepped onto the starting line.

Everything should be done by now.

Even if it's not finished.

There was no pause option for you.

You just have to keep doing it.

Thus, the following scene appeared—

Su Shen stood still in front of the starting blocks, his body in a half-squatting, bent-arm position.

The hip angle is locked at 110°.

Maintain a knee angle of 95°.

The torso forms a forward tilt angle of 32° with the ground.

The whole body is like a fully drawn composite bow.

The anterior superficial line and the anterior deep line of the arm are the core tension carriers of this bow.

Both palms should be completely flat on the ground.

The thumb and forefinger grip the ground forcefully in a "locking" shape.

The palmar aponeurosis is stretched instantly.

This tension is rapidly transmitted upwards along the radial wrist flexor muscle.

This causes the fascia on the front of the forearm to bulge like a taut string.

The tension chain of the anterior surface line is fully connected at this moment.

The tension of the radial wrist flexor muscle causes the long head and short head of the biceps brachii to contract synchronously, causing the muscle belly to bulge like a solid bulge, and the long head tendon to protrude clearly along the anterior side of the humerus.

The tension is transferred to the sternal part of the pectoralis major muscle.

The shoulder actively depresses 5-8cm, the pectoralis major muscle is stretched longitudinally, and the fascial texture is clearly visible due to tension, seamlessly connecting with the anterior trunk fascia.

Forming a continuous energy storage channel from "finger-wrist-elbow-shoulder-core".

At this point, the elastic fibers of the anterior superficial line of the arm have been stretched to 1.25 times their resting length.

Like a rubber band poised to unleash its power.

At the same time, the deep anterior arm line simultaneously enters a high-tension state.

The pectoralis minor muscle contracts subtly, firmly fixing the scapula to the ribcage, forming a rigid fulcrum, and preventing tension on the anterior surface of the arm from causing the shoulder to tilt forward.

The subclavian muscle tightens, reinforcing the shoulder joint capsule and ensuring that the stretching direction of the biceps brachii is precisely aligned with the axis of the humerus, without any lateral deviation.

The pronator teres and flexor digitorum profundus muscles form a subtle bulge under the skin, which connects to the deep palmar arch via the carpal tunnel fascia, converting the subtle tension of the fingers gripping the ground into pre-activation energy of the deep fascia.

The tension of the two anterior fascial lines is superimposed.

The arms, bent at 90°, act like two hydraulic rods filled with pressure.

The fascia around the elbow joint appears tight and shiny due to high tension.

The entire upper limbs form an energy storage state of "relaxed on the outside and tight on the inside".

Every inch of fascia fiber is silently accumulating elastic potential energy.

The core muscles work in conjunction with the two lines on the front.

The transverse abdominis tightens like a band, converting the tension transmitted through the deep anterior line of the arm into trunk rigidity, while the erector spinae maintains a slight isometric contraction, balancing the tension on the anterior side of the pectoralis major.

The force of the lower limb push-off is transmitted in reverse through the core fascial chain to the deep anterior line of the arm, which increases the total energy storage of the two anterior lines by another 15%.

At this moment, all of Su Shen's energy was channeled through the front double lines to form a closed loop with the starting blocks.

It can erupt instantly at the sound of a gunshot.

Bang————————

Bolt is truly remarkable.

With such a quick reaction, he almost immediately overpowered everyone, including Gatling, who had now changed his movement patterns and was adept at long-range shooting.

They were all pinned behind him.

Under such circumstances, it's clear how well Bolt started his run.

pity.

Again.

It is a pity.

When you do something extraordinary.

At this time, you'd better pray for one thing.

What is it?

That means you must pray that no one appears in your life who does something even more extraordinary than what you did.

If this person appears.

Even if you take your achievement out of the box, it's nothing short of incredible, and you'd be unbeatable in history.

But as long as you're by my side.

There's someone stronger than you by my side now.

People with a stronger visual impact.

Believe me, you will become the biggest tragedy in this game.

The biggest footnote.

If you don't understand what this means, watch Tyson Gay.

In the original timeline, he was dragged out and whipped countless times.

There's nothing we can do about it. Who asked him to use that shot and get that result when there's a terrifying 9.58 seconds next to it?

If this result hadn't been achieved on the original timeline, it would be his best result at the World Championships.

Without Bolt, this would have been the best result in the competition.

This achievement surpasses everyone in any major competition in history.

Except for Bolt.

Now you understand just how terrible it would be if such a situation really happened.
It can be said to be horrible.

Humans are such animals. You may be very strong, no matter how you analyze it, you are still very strong, but as soon as someone stronger than you appears around you.

That will attract everyone's attention.

You won't get a spotlight.

just now.

That's exactly what Su Shen needs to do.

You did a great job, Usain.

Defeat you, now upgraded again.

That makes people feel more accomplished.

No?
Bang——————

The gunshot pierced the air in an instant.

On the fifth path.

The elastic potential energy of the two front lines is released instantly in an explosive manner.

The whole process is lightning fast.

It only took 0.06 seconds.

Yet it presents a dynamic and layered visual experience.

The energy was detonated first on the front surface of Su Shen's arm.

The biceps brachii is like a spring that has been triggered.

The muscle belly contracts and bulges instantly.

The elastic fibers rapidly retract at a speed of 1.4 m/s.

Swing your forearm forward and upward.

The tension of the radial wrist flexor muscle drops sharply from 22N to 5N.

The tautness of the palmar aponeurosis instantly relaxes.

The force of the fingers gripping the ground is converted into a forward thrust, causing the hand to spring forward like an arrow released from a bow.

The tension in the pectoralis major muscle is released rapidly, the sternal fascia contracts forward, pulling the shoulder forward and downward, which in turn adds to the kinetic energy of the forward tilt of the torso.

At this point, the energy release power of the anterior brachial surface epithelium reaches 340W/kg.

For example, a small engine provides explosive power to the upper limbs.

Almost at the same time.

Precise control and energy transfer along the deep anterior arm line are carried out simultaneously.

The contraction strength of the pectoralis minor muscle increases instantly by 30%.

Firmly fix the scapula.

It provides stable support for the breakout of the anterior arm line.

Avoid shaking of the shoulders due to excessive tension.

The pronator teres muscle contracts rapidly, adjusting the wrist joint angle so that the trajectory of the forearm swinging forward remains parallel to the ground.

The horizontal component accounts for as much as 88%.

The deep fascia of the flexor digitorum profundus transmits energy upward to the pectoralis minor, activating the deep anterior core line, instantly doubling the contraction strength of the transverse abdominis.

Transfer the explosive energy from the upper limbs to the lower limbs.

It forms a "push-swing coupling" with the force of the quadriceps pushing off the ground.

At this point, the viscoelastic characteristics of the anterior deep line of the arm come into play.

The slow-release elastic potential energy and the fast-release energy of the anterior surface of the arm form a double peak superposition.

This extends the power output time to 0.1 seconds.

Avoid depleting energy instantly.

The dynamic images of the upper limbs are particularly impactful.

The elbow is bent at 90° and held for 0.03 seconds at the moment of initiation.

Then, it was quickly adjusted under the drive of the double-line tension of Su Shen.

The elbow angle increased from 90° to 105°.

However, it still maintains the curved arm shape to reduce rotational inertia.

The swing trajectory of the arms is a precise arc, with a forward swing speed of 3.8 m/s.

The theoretical improvement compared to the previous starting point can reach 3%.

The arms were like two accelerating paddles.

It propels itself forward by slicing through the air.

The fascia on the front of the forearm shows clear muscle fiber texture due to rapid contraction.

The fascia at the junction of the biceps brachii and pectoralis major muscles shows obvious fluctuations.

as if……

You can see the trajectory of energy flowing rapidly within the fascial chains.

The dynamic visuals of the entire body working in unison reach their peak at this moment.

The forward swing force of the anterior double lines is transmitted to the lower limbs through the core fascial chain, increasing the force of pushing off the ground by 28%.

The reaction force of the starting block push plate is transmitted upward along the anterior surface line of the lower limbs, forming an energy loop with the anterior deep line of the arm.

The torso maintains a rigid forward lean, with the shoulder axis parallel to the hip axis. The tension of the double lines on the front maintains the body's balance, preventing excessive forward leaning or swaying caused by explosive force.

The neck remains stable, aligning with the direction of force applied by the two lines on the front.

The entire body is like a missile precisely guided by two lines on the front.

It was launched horizontally.

hum-

After the outbreak is initiated.

Su Shen's body entered a transition phase of 0.3-0.5 seconds.

The front dual lines switch from "burst release" mode to "dynamic control" mode.

Guide your body to smoothly transition from a bent-arm start to the middle of the run.

The visuals are fluid and powerful.

The tension of the anterior superficial line of the arm decreases in a gradient manner.

The contraction strength of the biceps brachii slowly decreases from its peak, and the muscle belly gradually relaxes from a tense state, but still maintains 20% pre-contraction tension to maintain the inertia of the upper limb swing.

The tension of the radial carpal flexor muscle decreases as the wrist joint naturally extends, the palmar aponeurosis returns to a semi-relaxed state, the fingers gradually extend from the gripping position, but the thumb remains slightly tucked in to ensure that the tension of the fascial chain is not interrupted.

The fascial tension of the pectoralis major muscle adjusts synchronously with the rhythm of the trunk rising up, as the angle between the trunk and the ground increases to 4°.

The degree of stretching of the pectoralis major muscle gradually decreases.

The release of energy has shifted from an explosive to a steady pace.

This allows for the accumulation of new energy during the arm swing motion in the middle of the run.

Precise control of the deep anterior arm line becomes the core.

The contraction strength of the pectoralis minor muscle is dynamically adjusted according to the shoulder posture. When the torso stands up, the scapula gradually moves from a fixed state to an active state.

The pectoralis minor muscle adjusts its contraction strength in real time through tension feedback to prevent compensatory movements in the shoulder.

The pronator teres and supinator muscles work together to guide the forearm from a pronated position to a neutral position.

The elbow angle smoothly increases from 105° to 125°, and the forward swing trajectory gradually changes from horizontal to slightly upward, seamlessly connecting with the arm swing posture during the run.

The deep fascia of the flexor digitorum profundus works in synergy with the deep anterior core line, and the intensity and direction of the tension transmitted are adjusted in real time as the core muscle group exerts its force rhythm.

Ensure that there are no breaks in the transmission of energy between the upper limbs, core, and lower limbs.

This is in the moving images.

Su Shen's arm swings gradually changed from "ejection-style forward swing" to "inertial swing".

The swing arm angle continues to increase, but always maintains the optimal swing arm angle of 120°-130°.

The tension between the anterior superficial line and the anterior deep line of the arm is balanced, making the swing trajectory stable and efficient.

The fascia on the front of the forearm is no longer as taut as it was at the moment of initiation, but instead exhibits elastic fluctuations, with stretching and contraction of the fascia visible with each swing.

Like ocean waves, it transmits energy.

The movement trajectory of the shoulder is a smooth arc.

The fascia at the junction of the pectoralis major and the anterior deltoid muscles transitions smoothly without any stiffness or blockage.

It showcases a harmonious aesthetic achieved through precise control of the front dual lines.

Finally arrived.

The transitions between the full-body shots are fluid and rhythmic.

The tension regulation of the anterior double lines is completely synchronized with the rhythm of the lower limbs pushing off the ground. Each push-off of the lower limbs can trigger tension fluctuations in the anterior double lines, forming a coordinated closed loop of "push-off and arm swing".

The torso gradually rises to an upright position.

The tension of the two front lines smoothly transitions from the high tension state at the start to the stable tension state during the middle run.

Energy conversion efficiency has consistently remained above 75%.

The tension between the superficial and deep anterior arm lines is stable at 8-10N, maintaining the natural bending and swinging of both arms.

The mission of the front dual lines has shifted from "burst launch" to "continuous propulsion".

Provides stable power support for the entire startup process.

This is a visual detail of tension transmission.

It is the superposition of dynamic details of elastic deformation and retraction and dynamic connection details of coordinated force exertion.

then.

And that's how we came to be.

This is a scene that can be seen with the naked eye.

Su Shen.

It is like a bow that is full of elasticity.

He used a new fascial chain to apply greater pressure to his bowstring.

Then he let go for a moment.

But that's not it.

The bow is drawn as full as a full moon.

Swift as a shooting star.

This has never happened before. Launch control.

It's fast.

Even Su Shen himself.

Everyone was amazed.

Regardless of whether there is a previous history.

Regardless of whether there was a video recording beforehand.

Now, this kick.

This marks a new peak in human development.

No one can match him.

Including Su Shen himself before.

Same thing.
