The Su God of the Reopening of the Sports Arena

Chapter 2500 Ultimate Frontal Technology! You're fast, just not as fast as me.

Good to come.

Yussane.

How about I show you this trick?
If we can have a conversation.

Su Shen would definitely say that.

After Moscow, he discarded even the slightest bit of his disdain for Bolt.

The Battle of Moscow made him realize that Bolt is still Bolt, and he must be judged with an extraordinary perspective, without the slightest carelessness.

Unless you wear him out until he's old.

Otherwise, don't think so much.

So for the past two years, Suarez has been imagining Bolt as the greatest boss in history.

So now, what move has he made?

None of this would surprise Su Shen too much.

After all, it's been these past two years.

They're training hard, aren't they?
As a sacred body of track and field, it should have its own high standards.

The scientific training I've received over the past two years has definitely not been in vain.

In fact, this is also true.

but.

This is not Moscow anymore.

Do you think I'll let my guard down again?
Even if we know that Bolt achieved extremely high acceleration, so what?

The United States has always been the best in the global sports field in terms of customization and personalized technology, and Suarez is well aware of this.

but.

No matter how well you understand it.

Could someone possibly surpass my research into myself over two lifetimes?
Can you understand it better?
In sprint events.

The acceleration zone is the crucial stage for athletes to transition from a stationary state to maximum speed. Its core technical logic is to maximize the force efficiency in the horizontal direction through body posture control and kinetic chain transmission.

At this stage, Suarez will be showcasing the ultimate front-side technology.

This is not an optimization of a single movement, but the result of the synergistic effect of three factors: activation of the forearm fascial chain, standardization of the bent-arm start technique, and ultra-low center of gravity posture control.

That's right, you think you're the only one with a backup plan?

You want to play cards?
Having lived two lives, my assessment of you is definitely more comprehensive than your own.

Let's see who has more cards up their sleeve!
First, by utilizing the anatomical structure and functional characteristics of the forearm fascial chain, the composition and mechanical transmission path of the forearm fascial chain are activated.

As we all know, the fascia in the human body does not exist in isolation, but rather forms a continuous mechanical transmission network through the weaving of collagen fibers, connecting muscles, bones, joints, and other tissues into a unified movement unit. The forearm fascial chain is a branch of the posterior superficial fascial chain of the upper limb, and its anatomical components include:

The deep fascia on the posterior side of the forearm, the extensor carpi radialis fascia, the extensor carpi ulnaris fascia, the extensor digitorum fascia, the lateral bundle of the triceps brachii fascia, the posterior bundle of the deltoid fascia, and the inferior bundle of the trapezius fascia are indirectly connected to the posterior superficial fascial chain of the lower limb through the thoracolumbar fascia.

From the perspective of the mechanical transmission path, the forearm fascial chain originates at the insertion point of the extensor tendons of the 2nd to 5th fingers, extends upward through the deep fascia on the posterior side of the forearm, and connects to the lateral epicondyle of the humerus through the lateral bundle of the triceps brachii fascia.

It then connects to the lateral border of the scapula via the posterior deltoid fascia, and finally connects to the fascial attachment point of the spinous process of the thoracic vertebrae via the subtrapezius fascia.

The core characteristic of this transmission path is "fixed at the distal end and exerted force at the proximal end".

When the fingers and wrist joint remain extended and fixed, the fascia on the back of the forearm is under tension, forming a rigid mechanical transmission channel.

The force generated by the lower limbs pushing off the ground is transmitted to the upper limbs through the trunk, while the inertial force generated by the upper limbs swinging is transmitted back to the trunk, thus achieving the synergistic superposition of the power of the upper and lower limbs.

Although Su Shen did not remove all four fascial lines of the forearm fascial chain.

But having secured two of them is already sufficient.

Because at this stage.

During the acceleration phase of a sprint.

The forearm fascial chain mainly performs three core functions.

It is already sufficiently compatible with the technical requirements of the acceleration zone.

The first point is the "rigid link" function of power transmission.

In other words, when accelerating in a sprint, the ground reaction force generated by the extension of the lower limbs needs to be transmitted to the upper limbs through the torso in order to balance the body posture and improve the efficiency of arm swing.

The tension of the forearm fascial chain can reduce the "elastic internal friction" of the upper limb muscles and prevent the loss of force during transmission due to excessive muscle relaxation.

Compared to the relaxed state of the fascial chain, the rigid transmission mode can increase the inertial force generated by upper limb swing by 15%-20%.

However, this news is unlikely to be known by anyone now. This is based on 2018 sprint-specific research data published in the *Journal of Sports Biomechanics*.

It's only 2015, and this theory hasn't even been proposed yet.

Not to mention its application.

The second is the "restraint mechanism" function for joint stability.

The collagen fibers of the forearm fascial chain are tension-dependent—when the fascia is stretched.

Collagen fibers automatically align themselves into a parallel structure aligned with the direction of tension, thereby enhancing joint stability.

During the start and acceleration arm swing, if Su Shen's wrist joint maintains a dorsiflexion of 15°-20° and his elbow joint maintains a fixed angle of 90°-100° at this stage.

The tension of the forearm fascial chain can restrain excessive movement of the radioulnar and elbow joints, reduce the risk of joint injury, and ensure the consistency of arm swinging movements.

The third point is to utilize the "synergistic triggering" function of muscle activation.

Changes in the tension of the fascial chain can trigger reflexive contractions of the relevant muscles through fascio-muscle receptors.

When the forearm fascial chain is stretched due to arm swinging, it simultaneously activates the contraction of the lateral bundle of the triceps brachii, the posterior bundle of the deltoid, and the lower bundle of the trapezius, enhancing the power output of the upper limb during backward swing.

When the forearm swings forward, the relaxation of the fascial chain triggers eccentric contraction of the biceps brachii and brachioradialis muscles, storing elastic potential energy for the next backward swing.

This reflexive activation mechanism can improve the synchronicity and timeliness of muscle contraction and shorten the delay time of muscle exertion.

Then, the bent-arm start is combined with it.

This led to the development of the 3.0 version of the curved arm start.

The mechanism by which the flexed-arm start technique activates the forearm fascial chain.

For example, the pre-setting of fascial chain tension under posture constraints.

In the preparatory position, the elbow is bent at 90° and the wrist is dorsiflexed, which causes the deep fascia on the back of the forearm to be subjected to continuous passive stretching.

At this point, the collagen fibers of the forearm fascial chain change from a relaxed state to a tense parallel arrangement, forming a "tension pre-set" state. This means that the fascial chain has stored a certain amount of elastic potential energy before the movement is initiated, so that it can quickly enter a rigid transmission state without additional muscle contraction after the gun is fired.

For example, the dynamic tension adjustment of the fascial chain during arm swinging movements.

During the arm swing in the acceleration zone, the flexed arm technique keeps the elbow joint angle relatively fixed, and the power of the arm swing mainly comes from the rotation of the shoulder joint, rather than the flexion and extension of the elbow joint.

This movement pattern causes the tension of the forearm fascial chain to exhibit "periodic fluctuations"—during the forward swing, the shoulder joint flexes forward, causing the forearm to move forward, and the forearm fascial chain is slightly stretched, increasing the tension.

During the backward swing, the shoulder joint extends backward, causing the forearm to move backward, and the tension of the fascial chain reaches its peak. The periodic tension fluctuations can continuously activate the fascia-muscle receptors, triggering the coordinated contraction of the upper limb muscles and forming a "fascia-muscle" linkage force exertion pattern.

Compared to the arm swing mode that relies on active muscle contraction, this linkage mode can reduce the energy consumption of upper limb arm swing by 12%-18% while improving the stability of arm swing.

Then, based on one's existing physical characteristics, personalized adjustments are made.

Using a smaller forearm-to-ground angle can increase the initial stretch length of the forearm fascial chain, allowing for a higher degree of tension pre-set in the fascial chain.

Using a greater wrist dorsiflexion angle can activate the deep fibers of the wrist extensor fascia, enhance the connection strength between the fascial chain and the finger extensor tendons, and further improve the rigidity of power transmission.

During training, data on Suarez's starting movements can be collected using high-speed cameras.

The tension value of its forearm fascial chain in the ready position reaches 32N, far exceeding the average level of 20N for ordinary athletes.

It also far exceeds the 23N of elite athletes.
This means that Suarez's forearm fascial chain can transmit stronger force at the start, laying the power foundation for the front-side techniques in the acceleration zone.

Once you understand these prerequisites, you'll know what Su Shen is doing right now.

He wants to combine the techniques he developed in Moscow, which can only be used on wet tracks in rainy weather, with the techniques developed on the front side.

This enables the biomechanical coupling of the ultra-low center of gravity posture with the front-side technology.

When in the acceleration zone.

Su Shen's center of gravity can be less than 45% of his height.

The angle between the torso and the ground should be maintained between 20° and 25°.

The hip joint angle is less than 90°.

Compared to the previous acceleration technology with a torso angle of 30°-35°.

The ultra-low center of gravity posture has significant biomechanical advantages.

It has a strong advantage in increasing the proportion of force efficiency in the horizontal direction.

According to the principle of decomposition of ground reaction force, the ground reaction force generated by the lower limbs pushing off the ground can be decomposed into a vertical component (supporting body weight) and a horizontal component (propelling the body forward).

In other words, the smaller the torso angle, the higher the proportion of the horizontal force. Su Shen's experimental data shows that when Su Shen's torso angle decreased from 35° to 25°, the proportion of the horizontal force increased from 45% to 60%.

This means that more force is used to propel the body to accelerate, rather than to support the body's weight.

Then reduce the fluctuation range of the body's center of gravity in the acceleration zone.

This is because the vertical fluctuation of the body's center of gravity in the acceleration zone is negatively correlated with stride frequency.

Su Shen's vertical center of gravity fluctuation range under ultra-low center of gravity posture is only 8cm.

This is far below the average of 12cm for the world's top sprinters.

This allows its step frequency to quickly increase to close to 5 steps per second in the acceleration zone, laying the foundation for maintaining speed thereafter.

Then, the synergistic mechanism of the ultra-low center of gravity posture and the forearm fascial chain is combined.

The ultra-low center of gravity posture is not simply a matter of pressing the body down, but requires the dynamic coordination of the upper and lower limbs for support. Among them, the functional activation of the forearm fascial chain is the key condition for achieving the ultra-low center of gravity posture.

During running, the balancing effect of arm swing is enhanced.

Without these safeguards, in an extremely low center of gravity posture, Su Shen's body's gravity line shifts forward, which can easily lead to the risk of leaning forward and becoming unstable.

At this point, if the rigid swing arm resulting from the activation of the forearm fascia chain can generate a backward inertial force, it can balance the torque of the forward shift of the gravity line.

Specifically, when Su Shen accelerates the upper limbs backward, the rigid transmission of the forearm fascial chain causes the inertial force generated by the arm swing to be transmitted to the hip joint through the torso.

This creates a backward torque.

To counteract the tendency of the body to lean forward.

High-speed motion capture data shows that the inertial torque generated by the backward swing of Su Shen's upper limbs in the acceleration zone reaches 12 N·m, which is sufficient to support his 25° torso angle and maintain stability.

After balancing by swinging the upper limbs.

This allows for the coordinated superposition of the kinetic chains of the upper and lower limbs.

After all, in an ultra-low center of gravity posture, the force transmission path of the lower limbs pushing off is shorter.

The rigid transmission of the forearm fascial chain enables the force of the upper limb swing and the force of the lower limb extension to be vectored and superimposed at the trunk.

According to the principle of force composition, when the forces of the upper and lower limbs are in the same direction, the magnitude of the resultant force is equal to the sum of the two forces.

Su Shen's combined force peak in the acceleration zone reached 2500N, of which the force contributed by his upper limbs reached 25%. This proportion far exceeds the average level of 15% for ordinary athletes and also far exceeds the level of 20% for top athletes.

The core reason is that the rigid transmission of the forearm fascial chain improves the output efficiency of upper limb force.

He surpassed his previous high, which was also the highest he could not break through, reaching a percentage of 23%.

Then, in an ultra-low center of gravity posture, the lower limb muscles mainly work in an elastic mode of eccentric-concentric contraction.

The muscles of the upper limbs exhibit a rigid working mode of isometric contraction due to the activation of the forearm fascial chain.

The synergy of the two working modes enables energy complementarity—the elastic potential energy stored in the lower limb muscles is used for pushing and extending, while the isometric contraction of the upper limb muscles is used for postural stability, thereby reducing overall energy consumption.

Once all these preparations are complete, the front-side technology upgrade can be implemented.

Activation of the forearm fascial chain provides a rigid channel for power transmission, ensuring efficient force transfer.

The bent-arm start technique activates the function of the forearm fascial chain through posture constraints, thereby increasing the arm swing angular velocity.

The ultra-low center of gravity posture achieves the synergistic superposition of upper and lower limb power through posture control, thereby increasing the proportion of horizontal force efficiency.

The synergistic effect of the three forms a positive cycle of "fascia activation - arm swing acceleration - posture stability - force efficiency enhancement".

The ultimate front-side technology of the acceleration zone.

Its core characteristics are "shifting the body's center of gravity forward, rapidly increasing stride frequency, and continuously outputting horizontal force".

From a biomechanical perspective, this is the result of the synergistic effect of the forearm fascial chain, the bent-arm start technique, and the ultra-low center of gravity posture.

Su Shen.

This is where it will be shown.

For the whole world!

Bang bang bang bang bang.

He had just completed his final push-off onto the starting blocks at the 10-meter mark.

Su Shen did not rush to lift his body at this moment, but instead naturally adopted the extremely low center of gravity posture of the starting phase.

The upper limb swing and the lower limb extension movements are completely synchronized.

This forms a closed loop of coordinated force exertion between the upper and lower limbs.

At this time, the upper limbs maintain a rigid pattern of bent arm swing, the wrist joint maintains a dorsiflexion posture, the fingers are naturally extended, and the fascia on the back of the forearm is in a state of continuous tension.

To avoid loss of force during arm swing, ensure that the inertial force generated by the upper limb swing can be efficiently transmitted to the torso.

15 m.

When the lower limbs extend, the extension range of the knee and hip joints is precisely matched with the speed of the body's center of gravity moving forward.

The direction of pushing off the ground is not vertically upward, but mainly forward, using the ground reaction force to propel the body's center of gravity forward continuously, rather than undulating upward.

17 m.

Su Shen's torso maintained a very small angle with the ground, showing a clear forward tilt, with his spine in a neutral position and no bending or collapsing of the waist.

This posture keeps the body's center of gravity in front of the body, creating a forward diving tendency and providing a posture basis for continuous acceleration.

The elbow joint maintains a fixed bending angle without significant flexion and extension fluctuations. The forearm maintains a small angle with the ground, while the angle between the upper arm and the torso changes periodically with the arm swinging motion.

The angle decreases when swinging forward and increases when swinging backward. The swing arm trajectory is strictly in the forward and backward direction, without any left or right swaying.

19 m.

When the supporting leg touches the ground, the knee joint is bent and the ankle joint is kept in a moderate dorsiflexion.

Avoid the cushioning loss caused by a hard landing.

When swinging your leg forward, the height of your thigh should match the angle of your body's forward lean, without deliberately raising it.

Ensure that the swing can be quickly followed by a ground support.

20 m.

The head naturally follows the torso and stays tilted forward, with the eyes looking straight ahead at the ground, and the neck muscles are relaxed without any head-raising or head-lowering movements.

Avoid disrupting the stability of the body's center of gravity due to changes in head posture.

From the audience's perspective, the 10-20 meter segments of Su Shen's movements even presented a visual effect of "flying close to the ground".

Compared to other athletes, his body posture is lower.

The running trajectory is straighter, with no obvious ups and downs.

Su Shen's body seemed to be pulled forward by an invisible thread, his entire body leaning forward in a straight line, the line from his back to his buttocks to his heels almost parallel to the ground.

It gives people a visual feeling of "about to fall but being continuously pulled back".

Although the average viewer doesn't understand many of the principles of kinematics.

However, the audience can still clearly see that his arms remain bent at all times, swinging very fast and with a stable trajectory, and the amplitude of the swings is consistent.

The hand remains in a fixed position throughout the swinging motion.

There are no unnecessary swinging or flipping movements.

In stark contrast to the rigid swinging of the upper limbs, there was no obvious shrugging of the shoulders, and the movements were compact and efficient.

Coaches and spectators can see more details by comparing their perspectives.

For example, Su Shen's lower limb extension and swing frequency is gradually increasing, but the movement when landing is very light, and you can hardly hear any obvious footsteps. The process of the supporting leg from landing to pushing off is extremely short.

When the swinging leg swings forward, the thigh and calf fold together to a great extent, demonstrating a strong folding acceleration capability.

The entire lower limb movement is like precise gears meshing together, seamlessly connected.

Against the backdrop of the racetrack.

Su Shen's forward movement speed was significantly faster than that of other athletes in the same group, especially in the 15-20 meter range.

It was clear that he gradually widened the gap between himself and the athletes in the adjacent lanes, and this lead was not due to a sudden increase in stride length.

Rather, it stems from the ability to continuously accelerate.

It brings a strong sense of speed to the audience.

Even Bolt.

They were not spared either.

At most, the gap in lagging behind is relatively small.

Bang bang bang bang bang. The 20-30 meter mark is the critical segment in which Su Shen transitions from continuous acceleration to maximum speed, and the core technology shifts from "forward-positioned center of gravity propulsion" to "stretching frequency under stable center of gravity".

The execution of actions follows a sequential logic of "posture fine-tuning - frequency increase - power coordination".

Ensure the continuity of the acceleration process.

At 20 meters, the angle between the athlete's torso increases slightly compared to the 10-20 meter segment.

However, it still maintains an extremely low center of gravity.

This subtle adjustment is not a deliberate lifting of the body.

Rather, it is a posture optimization that naturally forms as speed increases.

The goal is to improve the efficiency of lower limb swing while maintaining a stable center of gravity.

The rigidity pattern of the upper limb flexion and swing remains unchanged, but the tension of the fascial chain exhibits periodic fluctuations, with a slight increase in tension during forward swing and a peak tension during backward swing.

This dynamic adjustment makes the inertial force output of the upper limb swing more rhythmic, forming a precise match with the increase in the lower limb cadence.

22 m.

The acceleration in this segment mainly comes from the continuous increase in stride frequency, the further shortening of the lower limbs' ground support time, and the increased speed of the swing leg's folding and forward swing.

The extension of the supporting leg and the forward swing of the swinging leg are highly coordinated to ensure that the propulsive force of each step can be efficiently converted into forward speed.

As speed increases, the power transmission throughout the body becomes smoother, and the inertial force generated by the upper limbs swinging and the ground reaction force generated by the lower limbs pushing off are efficiently superimposed at the torso.

The entire body forms a unified unit of force generation, without any compensation or disconnection in local movements.

24 m.

The angle between the torso and the ground is slightly larger than in the previous segment, but it is still much lower than the torso angle of traditional acceleration technology, and the spine remains in a neutral position.

The forward shift of the body's center of gravity increases in sync with running speed, with minimal vertical fluctuations in the center of gravity, ensuring stability during acceleration.

The elbow flexion angle remains stable, the range of fluctuation between the upper arm and the torso is further reduced, and the rhythm of arm swing is completely synchronized with the lower limb cadence.

When swinging forward, the hands reach the same level as the shoulders, and when swinging backward, the hands reach near the waist, resulting in a stronger symmetry in the arm swing.

26 m.

The knee flexion angle of the supporting leg when it lands is slightly reduced, the ankle dorsiflexion is further improved, the cushioning time at the moment of landing is shortened, and the force of the push-off is more short and powerful.

The height of the thigh is slightly increased when swinging the leg forward, but the folding forward swing is still the main method to avoid energy loss due to excessive lifting.

Keep your head in a stable position, keep your gaze level with the ground in front of you, and keep your neck muscles relaxed to ensure that your head posture does not affect the stability of your torso or the efficiency of power transmission.

Observed from the perspective of the audience at the Bird's Nest.

Su Shen's 20-30 meter segments presented a visual effect of "tight rhythm and soaring speed".

Compared to the previous segment, the movements are smoother and more fluid, and the increased stride frequency brings about a noticeable change in speed.

At this moment, Su Shen's forward lean angle decreased slightly, but he still maintained the trend of moving close to the ground. The trajectory of his entire body was smoother, and there was almost no vertical undulation.

It gives people the visual impression of "the body sliding parallel to the ground". Compared with the athletes in the same group, its body posture is more stable and the trend of speed increase is more obvious.

The swinging frequency of the arms increased significantly, with the bent elbows forming two rapidly rotating "arcs".

The swing trajectory has a high degree of symmetry, the hands maintain a fixed posture throughout the swing, and the shoulder movements remain compact without any unnecessary swaying.

Viewers can clearly feel the "pulling sensation" generated by the swinging of the upper limbs, as if the arms are propelling the body forward.

The rhythm of the lower limb movements is further accelerated, the extension of the supporting leg and the forward swing of the swinging leg are more closely connected, and the landing action is almost "one touch and then separation". The degree of folding of the swinging leg is extremely high, and the angle between the thigh and the calf is very small, showing extremely strong leg flexibility.

The entire lower limb movement was like a high-speed machine, with each link precisely connected and without the slightest delay.

The camera instantly focused!

Su Shen's torso pressed to the extreme angle with the ground, which is the core foundation of the front-side technique.

The spine is stretched into a straight mechanical transmission axis, extending from the back of the neck to the heels, without any bending or sagging compensation.

The tension of the forearm fascial chain is fully pre-set at this moment—that invisible fascial network, from the extensor tendons of the fingers all the way up, connecting the triceps brachii, deltoid muscle and all the way to the thoracolumbar fascia, is like a taut energy net, waiting for the opportunity to be released.

This is the unique mechanical advantage provided by the front-side technology:

The horizontal component of the ground reaction force was squeezed to its limit.

As the 10-meter marker line flashed past beneath their feet, what the audience could see with their naked eyes was the spectacular "ground-hugging flight" created by the technology in front.

Su Shen's torso maintained an astonishing forward tilt, without any attempt to get up. The bending and swinging of his upper limbs was not a simple back-and-forth swaying, but a rigid swing locked by the fascial chain—the elbow joint angle remained stable within a fixed range.

The angle between the upper arm and the torso changes periodically with the swing of the arm, and the fascial chain is slightly stretched when swinging forward.

The tension is instantly maximized during the backswing, precisely transmitting the inertial force of the upper limb swing to the extension trajectory of the lower limb through the torso.

The movements of the lower limbs are a perfect illustration of the anterior technique.

When the supporting leg lands, the angle of the knee joint bends precisely to match the front position of the center of gravity, resulting in no heavy impact, only a brief buffer and energy storage. The dorsiflexion of the ankle joint precisely controls the cushioning time upon landing, avoiding energy loss in the vertical direction.

The swing leg is not lifted high, but rather the hip is pushed forward in an extreme folding posture. The height of the thigh swing is strictly matched with the forward tilt angle of the torso. Each forward swing is to accumulate forward momentum for the next push-off, allowing the body's center of gravity to slide forward continuously, rather than undulating up and down.

At this moment, he is not "running".

Instead, it glides on a mechanical track constructed by the technology on the front side.

The ground's reaction force is almost entirely converted into forward thrust, with not a single bit wasted.

As the figure swept past the 20-meter mark, the forward technique entered a new phase of fine-tuning posture and increasing frequency. The forward tilt angle of the torso increased slightly, but this was by no means a deliberate effort to stand up; rather, it was a natural optimization of the forward technique after the speed was increased—the center of gravity remained firmly locked in front of the body, and the mechanical transmission axis of the spine did not shift in the slightest.

The tension of the forearm fascial chain begins to exhibit periodic dynamic fluctuations. The tension increases slightly during forward swing and reaches its peak during backward swing. This fluctuation is not out of control, but rather a manifestation of the coordinated force exerted by the fascia and muscle in the anterior technique.

Changes in the tension of the fascial chain trigger coordinated contraction of the upper limb muscles through receptors, allowing the frequency of arm swing to resonate perfectly with the stride frequency of the lower limbs.

In the audience's view, the frequency of his arm swings suddenly increased, but it was still the rigid trajectory required by the forward technique - the bent elbows turned into two blurry afterimages, and the amplitude of the back-and-forth swings was as symmetrical as a precision instrument.

Without any unnecessary swaying from side to side, each swing provides a stable balancing torque to the center of gravity in front, counteracting the inertia of the body leaning forward, allowing the shadowy figure close to the ground to always maintain an efficient forward movement.

The lower limbs' stride frequency is further increased, the ground contact time of the supporting leg is shortened to the extreme, the force of the push-off is short and precise, and the folding and forward swing of the swing leg always revolves around the front center of gravity.

Each leg lift and hip thrust extends the power chain of the preceding technique, allowing speed to continuously increase in a stable posture.

That swift shadow was able to achieve incredible acceleration.

This is a full display of cutting-edge front-side technology.

The ultra-low front center of gravity maximizes the proportion of horizontal force efficiency.

Rigid forearm fascial chain conduction allows for perfect superposition of upper and lower limb power; stable arm flexion and swing, and folding and extension.

Let every inch of strength serve the purpose of moving forward.

This is not a chance burst of talent, but an inevitable result of the deep integration of technology, anatomy, and mechanics.

Su Shen was like a whirlwind shaped by the front-side technique.

It is charging towards the middle track area with unstoppable momentum.

Mills, who always liked to sit here to watch the game, suddenly had his pupils contract.

As a gold medal coach who has trained countless sprint stars, he has seen too many exceptionally talented athletes.

But I've never seen such an accelerating posture before—the torso leaning forward at its maximum angle.

When the arms swing, there is no unnecessary swaying in the rigid trajectory; when the lower limbs push off, there is no upward wasted energy, only explosive force that moves forward.

It's as if every detail is precisely aligned with the optimal solution in biomechanics.

What technology is this?
Is this the ultimate front-side technology?
But why does it look a little different?

Front-side technology is impossible, isn't it?
He had studied this theory repeatedly in the training videos.

As a coach, he certainly understands the use of front-side techniques.

Even though Su Shen has brought this technology to the forefront in recent years, he still doesn't seem to want to change it, since there isn't much difference in technology between the front and rear sides.

However, the book on anterior mechanics that he co-authored with Ralph Mann.

That's what he's focusing on.

Yes, the average viewer may not be able to distinguish the relationship between front-side technology and front-side mechanics, but it's impossible for them not to know.

But what about now?

Yet it was presented to us in a way that almost defied our understanding.

The teaching assistants around him were already in an uproar. Some of them subconsciously rubbed their eyes, thinking that the sunlight was too strong and their vision was blurred.

Someone clenched their fist, their knuckles turning white from the force, muttering to themselves, "Impossible, the center of gravity is too low, how can they run so fast?"

Mills' breathing suddenly became heavy. He leaned forward and stared intently at the moment Su Shen crossed the 20-meter mark—the figure did not get up despite the increase in speed.

Instead, he maximized the advantage of his ultra-low center of gravity, with a stride frequency so fast that it almost left a trail of afterimages, widening the distance between himself and his opponents.

He knew all too well what this meant.

This is not simply a burst of talent, but a technological system that completely outclasses traditional sprinting logic.

All previous doubts about the "upper limit of front-side technology" were completely shattered at this moment.

Mills' throat bobbed as if he wanted to shout something, but found his voice stuck in his throat.

My chest was filled with shock, disbelief, and an indescribable sense of awe.

Until that dark figure swept across the 30-meter mark, completely consolidating his advantage, it was impossible for Bolt to catch up.

Francis, who was already standing with Powell in the coaches' viewing area, slowly straightened up, also shocked by what he had just witnessed.

Because Mills knew these basic facts, he certainly knew them too.

This is definitely not a simple front-side technology.

Because simple frontal techniques and the frontal techniques he knows absolutely do not have this capability.

Absolutely not!
Francis subconsciously wiped the cold sweat from his forehead and whispered, "He's mastered the technique to the bone."

"This... may be the ultimate form of sprint acceleration."

Even he had to think about it.

Let's just consider this possibility.

You can remove it or not.

Because this is within his mind and cognitive theories.

A state that cannot be achieved.

but now.

There are people there.

It has been accomplished.

Right under my nose.

You have no choice but to believe it.

The group of American sports researchers standing next to Francis completely lost their usual composure and self-control at this moment.

Each face was filled with professionalism and confidence.

Complete shock and astonishment replaced it.

The high-speed cameras in their hands are still operating stably.

On the real-time monitoring biomechanical data panel.

All the parameters were fluctuating wildly, but no one paid any attention to those cold, hard numbers anymore.

All eyes were fixed on the figure sprinting along the track, hugging the ground. Some people subconsciously pushed up their glasses, as if that would allow them to see the mind-blowing movement patterns.

Some people were clutching their notebooks so tightly that they were deformed, and their fingertips turned white from the force.

Some people couldn't help but let out suppressed gasps, repeatedly muttering—

"Shet."

"Fake."

"You thief, Ah Mei."

Comments like "This doesn't fit the model" were common.

These researchers, who have been immersed in the field of sprint science for many years, have already used hundreds or thousands of sets of data to construct an "optimal solution model" for acceleration zone technology.

In their understanding, an ultra-low center of gravity inevitably carries the risk of loss of balance, and the force exertion mode of a rigid swing arm is destined to limit the increase in stride frequency.

But the scene before them shattered the theoretical framework they held as gospel.

Because his torso was firmly locked in place by that technique that was being used to unleash the ultimate frontal movement.

There was no sign of imbalance whatsoever.

Rigid swing arm driven by the forearm fascial chain.

Instead of slowing down the pace, it created a perfect dynamic resonance with the extension of the lower limbs.

The horizontal propulsion force was squeezed to an astonishing degree.

When Su Shen crossed the 20-meter mark and the gap between him and his opponent widened suddenly, a low commotion broke out in the crowd.

A senior researcher with gray hair suddenly stood up from the folding chair, looking quite composed as before.

Or perhaps they possess considerable pride.

But now.

However, because he stood up too quickly, he almost knocked over the testing equipment next to him.

He stared intently at the receding figure, his cloudy eyes filled with shock, muttering to himself:

"Deconstructed..."

"The technological logic we've studied for decades has been completely reconstructed by this Eastern technological system..."

The logic of reality is...

It's done.

He is logic itself.

What you call logic.

Faced with reality.

worthless.

And Su Shen is now telling the whole world.

Ultimate front side.

It is the gateway to speed in the future.

Bolt is indeed very fast here.

I'm very sorry.

Su Shen.

The red figure next to him.

Faster.

In the realm of sprinting, even if you achieve a historic performance, you're still at a disadvantage as long as someone else is holding you back.

That would seem...

You're not running fast enough.

At least visually.

That's it.

No wonder Maurice Green, who was broadcasting the game live, started yelling when he saw this:

"This is insane! What kind of acceleration is this?!"

"Even if the Flash came, he wouldn't be any better!"

"Human acceleration has reached a new level!"

I am very sure of that.

Moreover, ever since Su Shen came into this world.

The acceleration step of human beings.

It has been continuously improving.

So far.

I haven't encountered any bottlenecks yet.

Bolt, who was behind, had already pulled away from the others.

But as soon as you slowly look up and see that figure in front of you...

He always felt that this guy was telling him something through his back...

You're fast!

But I...

Faster.
