The Su God of the Reopening of the Sports Arena

Chapter 2428, page 9.49! Is this Bolt returning after his studies?

Su Shen declared, "Stop dawdling and get to the intensity!"

9.50 is not a game for people of our skill level. Let's get serious.

Suarez strongly urged Bolt to end his warm-up.

……

Bolt had nothing to say when he saw the news; he knew that now he only needed to let his results speak for themselves.

Wait until the Jamaican selection trials begin.

He would naturally let Su Shen know.

He is ready too.

Meanwhile, other news from the track and field world was also being updated. After all, this year is a year of major competitions, and all sorts of records are being broken.

日本石川县能美举行的2015国际田联竞走挑战赛中，日本选手铃木雄介以1小时16分36秒的成绩创造了新的男子20公里世界纪录，打破了法国选手尤安·蒂尼兹在3月9日举行的法国田径锦标赛上创造的1小时17分02秒的纪录。

Japanese media recently reported that Yusuke Suzuki received more than 1 million yen in prize money from sponsors and the Japan Athletics Federation.

2012年伦敦奥运会，中国运动员陈顶以1小时18分46秒获得男子20公里竞走，并打破奥运会纪录。2013年的莫斯科世锦赛，罗斯90后选手伊万诺夫以1小时20分58秒获得冠军，中国选手陈顶以1小时21分09获得银牌。应该说竞走是中国田径的传统强项，男子20公里竞走是近年来中国田径在世界顶级大赛中的抢金夺牌利器。

However, the world record for the men's 20km race walk has been constantly being broken in recent competitions, and even Yu Weili, director of the Track and Field Management Center, recently issued a statement:
"Recently, French and Japanese athletes have achieved excellent results in the men's 20km race walk, which poses a serious challenge to our race walkers and increases the difficulty of preparing for the World Championships. We must further improve the strength of our athletes in the coming months in order to have a chance to compete with our opponents in the World Championships."

Tokyo, Japan, will once again host the 2020 Olympics, leading to a gradual increase in their focus on sports in recent years. The Japan Athletics Federation (JAAF) has offered substantial bonuses to incentivize the country's track and field athletes to achieve outstanding results. Yusuke Suzuki's world record break will earn him over 1 million yen in bonuses from sponsor Fujitsu and the JAAF.

值得一提的是，在北京时间3月20日进行的2015年全国竞走大奖赛BJ站比赛中，伦敦奥运会铜牌得主王震以1小时19分29秒的成绩获得冠军，伦敦奥运会冠军陈顶以1小时21分11秒获得第三。

Compared to the performances of French athletes Joan Tiniz and Yusuke Suzuki, our Olympic medal-level athletes no longer have an advantage.

Of course, there's also the usual gossip.

Trackalerts.com, a track and field website, reported that a new luxury mobile phone has recently been launched, and Jamaican sprint star Usain Bolt is its owner. The phone is valued at £230 million, approximately $360 million (2219 million RMB). The manufacturer joked that this phone could buy a small island.

Usain Bolt spends every summer in Teddington, England, making the country practically his second home. Goldgenie, the renowned British luxury brand that manufactures the phone, has a CEO, Laban Rummuz, who says, "This is arguably the most expensive phone in the world today; I have to say it's worth an entire island."

This is a 24k gold-plated iPhone 6, and even more extravagantly, it's surrounded by numerous small, valuable diamonds. This is from a personalized luxury goods manufacturer, who reportedly can also customize the phone's body with pure gold, pure white gold, or even rose gold upon request.

It's nothing in itself; after all, everyone makes different choices.

But at this point, Su Shen's fans were unhappy.

"are you joking?"

"Bolt actually owns a phone that's more expensive than Suarez's?"

"Leaving aside the issue of wealth ownership, aren't there any other brands that should step forward and say something?"

"And on Apple's side, I remember Su Shen is one of their major individual shareholders, right? Are we just going to watch it like this?"

This matter might not have been a big deal at first, but after it went viral online, many brands suddenly seized the opportunity and made adjustments.

Rolex has stated directly that they are willing to custom-make a £500 million phone for a private client if needed.

Seeing that Rolex had said this, other brands were not to be outdone.

After all, this is a massive amount of traffic.

This is a bit too exaggerated.

Of course, Apple itself is still the best at operating. Although their innovation has declined since Jobs left the company, their business performance and sales have continued to rise.

Cook is indeed a more astute businessman and a better salesman.

He probably can't come up with anything new for Apple.

But it will definitely make the company more valuable.

Then we can't miss this kind of topic.

Of course, he didn't appear in person; instead, an Apple spokesperson said it directly during an interview.

If needed.

Of course, we will customize a phone for Su worth over ten million yuan.

After all, he has a share in our business.

A tiny bit leaked out.

They cost more than that.

They can even argue about this.

It is clear that the competition between the two sides has now reached a fever pitch.

The kind of fans could start fighting at any time.

Jamaica National Championships.

Bolt, Blake, Carter, Powell, Ashmead, Bailey Cole...

Big names like them made it to the final round.

In the finals.

A gathering of big names.

There are so many superheroes here in just one national competition in Jamaica.

It was a complete crushing defeat for the United States.

The U.S. Championships, once a mini-Olympics that the United States was very proud of.

At least 100 meters of this project has now been replaced by Jamaica.

And you never know if there are some young geniuses watching this group of experts from the audience.

I dream of becoming one of them in the future.

"This race is mainly to see how fast Bolt can run. You know, Suarez on the other side delivered a time of 9.52. I hope Bolt can withstand the pressure and, with the cooperation of so many top athletes, reach a new height."

"Help us get WL back to Jamaica."

The commentator finished speaking.

The audience at the scene was already in a frenzy.

"Go Usain! Go for it!"

"Kill Dongfang Su!!!"

This type of sound was heard everywhere in Jamaica's National Stadium.

This kind of competition between national athletes easily draws in the emotions of ordinary people.

After all, everyone hopes their athletes can have the last laugh.

This is the simplest wish.

They were lined up in a row.

When I returned, the gunshots rang out.

bang————

Blake: Neural overtuning activation creates a "catapult-like" startup.

Blake's activation is the ultimate example of "neural dominance," seizing the initiative with "neural overtuning activation" technology. When he is "on his feet," his hands are positioned 5 degrees inward on the ground, with his fingers in a semi-bent state, deliberately shortening the transmission path of nerve signals from the brain to the arm muscles.

During the preparatory phase, all muscles enter a "pre-excitation state," with the calf muscles exhibiting high-frequency micro-tremors, the hip joint slightly adducting, and the muscle spindles and tendon organs entering a "signal sensing mode" in advance, rather than the usual static tension.

The moment the gun fires, the central nervous system sends an "overshoot command" to the muscles.

The signals for pushing off the ground with the lower limbs and swinging the arms are sent synchronously, and the arm swinging motion even starts 0.01 seconds earlier than the push-off.

He breaks the natural reflex of "pushing off the ground first and then swinging his arms," ​​using the inertia of arm swing to pull his lower limbs to generate force more quickly. From a sports physiology perspective, his neural reaction time is only 0.179 seconds, which, while not exceptionally good, is better than his previous performance.

That's still a pretty good result.

At least it's not a snail's pace.

It wasn't enough for others, but for Blake, it wasn't enough.

That's more than enough.

The push-off motion uses a "stepped burst" technique.

The hip joint first completes the swing and builds up power in 0.02 seconds, then the knee joint extends from a slight flexion to 135° in 0.01 seconds, and finally the ankle joint is stretched to its limit to complete the "ground launch". The heel of the pushing leg is instantly raised to the buttocks without any cushioning process.

This "joint-level burst" allows the ground reaction force to be transmitted in a "superimposed" manner, with the impact force generated when the foot hits the ground reaching 2.5 times the body weight, propelling the body forward at an acceleration of 0.8 m/s.

When swinging the arms, the elbow angle is fixed at 90°. When swinging backward, the scapula contracts violently, and the forward swing amplitude exceeds the waist. The inertia of the upper limb swing further amplifies the forward movement speed of the center of gravity.

His start was devoid of any superfluous movements; it was a complete "lightning-fast coordination" of nerves and muscles, perfectly embodying the "explosive power gene" of Jamaican sprinting.

At least do that, but given the current startup and future prospects.

It has improved considerably.

This was also the improvement phase that Blake had originally planned to undertake.

However, in the original timeline, he had to put it on hold due to injury.

However, this problem does not exist on this timeline.

He can certainly train well.

Asafa Powell, on the other hand, had an explosive start, but he began to incorporate core anchoring and transmission here to maintain a "steady-fast balance".

At the moment the gun fires, the core muscles perform alternating contractions with the waist and abdomen as the axis.

When the left leg pushes off the ground, the muscles in the right waist and abdomen contract simultaneously, transmitting the power of the lower limbs upward along the spine, without any loss of power when passing through the shoulders and back.

When the right leg pushes off the ground, the left side of the waist and abdomen takes over the force, forming a closed-loop transmission from the core to the upper and lower limbs.

This "core anchoring" design keeps the power loss rate below 8%, which is 3% lower than Blake's start. Although it sacrifices a 0.01-second start speed, it gains higher movement stability.

The push-off motion adopts an "elastic burst" mode: after the forefoot touches the ground, the ankle joint first performs a very short cushioning of 0.02 seconds, as if stepping on a spring to complete the energy storage, and then the knee joint extends to 130°, and the heel of the pushing leg is raised to the middle of the thigh, preserving the elastic potential energy of the calf muscles.

When swinging the arm, the elbow angle should be dynamically adjusted between 90° and 95°. The amplitude should be moderate when swinging backward and naturally extend in the direction of core traction when swinging forward.

This avoids energy waste caused by excessive arm swing.

After so many years of running, Powell has finally begun to find a breakthrough in his technique.

Body stability.

It brought a tremendous sense of breakthrough.

In addition, there is his accumulated experience.

He still maintains a good physical condition.

Instead, new breakthroughs in the integration of technology and the body have gradually emerged.

Nesta Carter, on the other hand, took a pragmatic approach to activating slow-twitch muscle transition.

As a "short-statured athlete," Carter's starting technique revolves around "low-loss transition," and he employs a "slow-motion muscle activation first" strategy to address his characteristic of "strong power in the later stages."

When “set”, shift your body weight slightly back, support yourself with your hands on the ground with moderate force, and completely relax your shoulder and back muscles.

The calf muscles activate slow-twitch fibers first, while fast-twitch fibers are in a "semi-resting state." The hips are raised 8 centimeters lower than other athletes, and the core muscles maintain a "low-tension" state.

After the gunshot, the lower limb push-off is primarily driven by slow-twitch muscle fibers, with only 30% of fast-twitch muscle fibers being activated.

When the ball of the foot strikes the ground, the ankle joint uses the continuous force of slow-twitch muscle fibers to cushion the impact, and the range of motion of the knee joint is controlled at 120°.

The heel of the rear leg is not deliberately raised, and the cushioning time when the front leg lands is extended to 0.03 seconds, reducing joint impact.

The arm swing is small and compact, with the elbow angle fixed at 105°, relying solely on the arm's own weight to swing naturally, minimizing upper limb strain.

Ashmead's strategy involves a lightweight, high-intensity launch to balance speed and range.

The core of the launch is "lightweight burst".

Given the slightly weaker fatigue resistance of its fast-twitch muscle fibers, the goal is to ensure a fast start-up speed while avoiding over-activation of the muscles.

Before firing the gun.

His hands were shoulder-width apart, his fingers were naturally curved, and his palms were in a "semi-adhesive" position to the track.

It ensures both support and stability while avoiding upper limb tension caused by excessive force applied to the fingers.

In the "set" phase, the hips are raised to 2 centimeters above the knees, and the calf muscles make "low-frequency micro-tremors" to activate only the "basal excitability" of fast-twitch muscle fibers, rather than entering a high-intensity pre-tension state like the predecessors. The angle between the hip and knee joints is kept at 32°, and the body's center of gravity is slightly leaning forward to leave buffer space for exertion.

At the moment the gun fired, his muscle activation followed the principle of "gradient burst," first activating the gluteus maximus and quadriceps femoris, and then simultaneously activating the calf muscles 0.02 seconds later, forming a force sequence of "lower limb core exerting force first, followed by the extremities," avoiding rapid fatigue of fast-twitch muscle fibers caused by a single high-intensity activation.

From the perspective of exercise physiology, his fast-twitch muscle fiber activation rate was controlled at 60%, which is lower than Blake's 70%, but his neural reaction time was still maintained at a high level of 0.13 seconds, achieving a "balance between speed and endurance".

The push-off motion employs a "short-range, high-efficiency power generation": after the forefoot touches the ground, the ankle joint only provides a very short buffer of 0.01 seconds, and the knee joint extension is controlled at 132°. It does not pursue the ultimate explosiveness of "fully straightening" but aims to "quickly complete the power generation cycle". The heel of the rear leg is raised to the lower part of the thigh, reducing the range of motion to save energy.

When swinging your arms, the elbow angle should be dynamically adjusted between 92° and 95°. The forward swing should not exceed the waist, and the scapula should be slightly contracted when swinging backward to avoid excessive swinging and consuming upper body strength.

His start lacked the explosive power of his predecessors like Bolt, Carter, and Powell.

However, through its "lightweight" design, it maintains speed while reserving 15% of the energy for fast-twitch muscle fibers in the subsequent acceleration zone.

Very thoughtful.

It's a pity that his potential is not high.

His talent level is incomparable to that of the previous generations.

Bailey Cole, on the other hand, adopted an aggressive approach to transitioning and starting, trading speed for efficiency.

What does it mean to achieve both efficiency and speed in connection?

In response to its characteristic of "rapid transition from start-up to acceleration", it adopts "aggressive center of gravity transfer" technology to shorten the connection time between start-up and acceleration.

His hands were 5 centimeters narrower than usual when he braced himself on the ground, and his elbows maintained a 115° "force angle".

By reducing the support area, the distance of the center of gravity shift is reduced.

The hips were raised 3 centimeters higher than other competitors, the calf muscles were taut but not trembling, the hip joints were slightly retracted, accumulating potential energy like a "fully drawn bowstring", the body's center of gravity was in a "critical forward lean" state, supported only by the forefoot and the edge of the palm, ready to complete the rapid forward shift of the center of gravity at any time.

The moment the gun fired.

His core muscles use "rapid twisting" to propel the shift of his center of gravity: the abdominal muscles complete a small-amplitude rapid cycle of "left twist-right twist" within 0.03 seconds, driving the center of gravity forward quickly from the support point, reducing the center of gravity shift time to 0.07 seconds, which is 20% faster than a conventional start.

This "radical shift in focus" essentially involves rapidly and dynamically adjusting the core to minimize the transition time between the three stages of "static-start-acceleration," thus avoiding the "rhythm gap" of a conventional startup.

The push-off motion is closely linked to the weight transfer.

When the left leg pushes off the ground, the inertia of the core twisting to the left propels the left leg to swing back quickly.

When the right leg pushes off the ground, the core force that returns to the right drives the right leg forward. The range of knee flexion and extension changes dynamically between 128° and 135° with the rhythm of the center of gravity shift. The goal is not to maintain a fixed angle of force, but to "adapt to the movement of the center of gravity".

In terms of arm swing, the forward swing speed of the arm is faster than the push-off speed. With the help of the inertia of the upper limbs, the center of gravity is further pulled forward, and the elbow angle is quickly switched between 88° and 92°, forming an aggressive rhythm of "fast swing and fast push-off".

Overall, it's good, and breaking 10 should be no problem.

It's just moving forward.

It was a bit difficult.

Of course, the most eye-catching one is...

Usain Bolt.

The technique he used here is—

Dynamic center of gravity shift.

Reserve room for acceleration.

Bolt's current starting strategy revolves around "connecting with subsequent acceleration," employing "dynamic center of gravity transfer" technology. It does not pursue the ultimate starting speed but rather lays the groundwork for an upgraded power delivery within 10-30 meters.

This is because his team also knows that it is extremely difficult for someone of Bolt's height to break through in the first 10 meters, and he has already reached the pinnacle of that height.

Look at an athlete as tall as him, how many can run the first 10 meters under 1.85 meters?
There are really very few, and let alone 1.8 seconds, there are plenty of skilled runners who are much shorter than him who can run the first 10 meters in 1.9 seconds or even 2 seconds.

The cost of laboratories in the US is not enough to allow him to reach the limits of his body's capabilities.

There's no need to put more effort into this.

The main reason is that the returns are too low.

not worth it.

The focus should still be on other aspects.

Moreover, this way, there's no need to worry too much about starting it up.

It allows for greater freedom.

When he heard "set", his hands were 10 centimeters wider than his shoulders as he braced himself on the ground, his palms lightly touching the track rather than clenching, and his shoulder and back muscles remained relaxed.

This is to increase the support area.

This allows for greater flexibility in adjusting the focus of the shift.

Before firing the gun.

Bolt raised his hips 3 centimeters lower than usual, maintained only basic tension in his calf muscles, widened the angle between his hip and knee joints to 35°, and shifted his center of gravity slightly backward, breaking away from the traditional "forward-pressing" preparatory posture.

At the moment the gun fires, the core muscles do not "contract alternately," but rather make a slight twist of 0.5° around the "waist and abdomen as the axis."

When pushing off with the left leg, the core rotates slightly to the left, smoothly transitioning the center of gravity from the back foot to the front foot.

When the right leg pushes off the ground, the core rotates to the right, shifting the center of gravity forward. This is a "dynamic torsional weight transfer".

This reduces the time it takes for the center of gravity to shift to 0.08 seconds.

It starts up 15% faster than a regular startup.

It also avoids the stiffness caused by the traditional "straight forward press".

The push-off motion is a "gentle burst".

The ankle and knee joints exert force simultaneously, but the extension force is controlled at 70%. The heel of the rear leg naturally rises to the mid-thigh, without deliberately pursuing a "launching sensation".

When swinging your arms, the elbow angle should be increased to 100°, the forward swing should not exceed the waist, and the scapula should be slightly contracted when swinging backward. The movement should be relaxed and slow, with the sole purpose of "maintaining balance".

This avoids energy waste caused by excessive arm swing.

Bolt's previous starting arm swings were still a bit too casual.

This issue has been addressed through adjustments made by American laboratories over the past two years.

It's getting better and better.

I'm becoming less and less impatient.

Actually, because Bolt has been training in the United States for the past two years, he has had very few competitions in China.

There have been no major competitions in the past two years.

It's fair to say that even for many Jamaican athletes, this is the first time they've seen him recently.

Ten meters later, Bolt's "dynamic core" instantly switched to "rigid transmission mode," which was the key to his acceleration and overtaking.

The abdominal muscles shift from "slight twisting" to "continuous tension," and the contraction strength of the rectus abdominis and external oblique muscles increases to 80%, fixing the thoracic cavity and pelvis into a "rigid whole" to avoid the loss of power caused by trunk twisting during acceleration.

The erector spinae muscles work together to maintain the straightness of the spine, allowing the force of the lower limbs pushing off the ground to be transmitted "without loss" along the spine.

The efficiency of force transmission increased from 85% in the initial stage to 92%.

At around 15 meters, his hip extension technique begins to "pre-start," not by isolated hip swing, but by deep integration with core rigidity: when the left hip moves forward, the right waist and abdominal muscles contract synchronously, directly converting the core-transmitted force into the forward swing force of the hip. Although the hip extension amplitude is only 5 centimeters, it increases the stride length by 3 centimeters.

When the right hip is extended, the reaction force of the right leg pushing off the ground is used to push the hip forward, forming a "core-hip-push-off" linkage.

Bang bang bang bang bang.

After 20 meters, Bolt's push-off technique shifted from "building up power" to "explosive power".

The logic behind the effort has completely shifted towards "adaptation during the journey".

He no longer retains any redundancy in core and lower limb power generation, and directly maximizes his push-off intensity to 90%.

This intensity is not "blindly exerting force," but rather through the rigid transmission of the abdominal muscles, precisely focusing the power on the moment the feet touch the ground.

From a biomechanical perspective, his knee flexion and extension range has increased to 145°. This angle has been refined over a long period of time, which can maximize the force stroke of the quadriceps while avoiding muscle stiffness caused by excessive extension, making the force of the back leg more elastic rather than "forceful pushing".

The contact method between the foot and the track has also been optimized, and the ground contact time has been compressed to an extreme range of 0.07 seconds.

When the forefoot lands, the ankle joint first performs a slight cushioning at millisecond speed, quickly absorbing the ground reaction force like a spring. Then, it uses the elasticity of the calf muscles to complete the push-off, and the whole process is without any delay. This achieves a highly efficient cycle of "power generation upon contact with the ground and lift-off upon power generation".

This short-duration, high-intensity push-off pattern creates a "cumulative effect" with each step, rapidly extending stride length and breaking through the initial range to the advantageous range during the middle of the race.

The stability of his power delivery rhythm was key to his comeback.

The core maintains a precise forward tilt angle of 32°, with the shoulder line parallel to the hip line as if measured with a ruler, without any swaying despite the increased intensity of pushing off the ground.

The coordination between arm swing and push-off has also entered a state of "seamless adaptation". The elbow angle is dynamically and slightly adjusted with the rhythm of force exertion. When swinging back, the contraction of the scapula matches the intensity of the lower limb push-off. When swinging forward, the extension direction of the arm is precisely pointed to the front of the track. Every swing is like "calibrating the course" for the body, avoiding unnecessary movements that consume energy.

At the 25-meter mark, Bolt's efficient ground-pushing technique fully unleashed its advantages. The moment he overtook Powell was not accidental, but a direct reflection of the upgrade in his "core-ground-pushing" transmission system after training in the United States. During his thousands of hours of practice at the Texas training base, he focused on optimizing the "synchronization between core rigidity and lower limb power generation."
At this moment, the abdominal muscles act like a steel-cast support, locking the ribcage and pelvis into an absolute straight line. When the left leg pushes off the ground, the contraction force of the right waist and abdomen increases by 20% compared to earlier years. The power is transmitted along the spine to the shoulders and back without any loss of force. Then, through the precise coordination of the arm swing, the inertia of the upper limbs is converted into additional forward thrust.

This "full-body coordinated power generation" increased his propulsion by 15% with each step compared to before training. When he overtook Powell, his torso maintained a stable 32° forward lean without any swaying caused by excessive acceleration.

It has completely overcome the shortcoming of "being prone to imbalance after startup" in its early years.

Entering the 27-meter mark, his ground-pushing technique further shifted towards a "late-race exclusive mode".

During training in the United States, breakthroughs in "stride length extension and power efficiency" began to emerge: the range of knee flexion and extension stabilized at 145°. This angle, repeatedly calculated by biomechanical instruments, maximizes the power stroke of the quadriceps while avoiding muscle tension caused by excessive extension.

When the foot strikes the ground, the contact point between the forefoot and the track is precisely located directly below the body's center of gravity, reducing the offset by 3 centimeters compared to before training, and increasing the utilization rate of ground reaction force from 85% to 93%.

With each push-off, the heel of the pushing leg smoothly lifts off the inner thigh without any extra movement. This "smooth push-off" is the result of his training by correcting the details of the movement frame by frame using a high-speed camera, completely eliminating the inefficient habit of "turning the heel outward after pushing off" from his early years.

At 28 meters, he had already overtaken most people. After Powell adjusted his position, he became less of a threat to those in front of him.

The technological competition has now reached a fever pitch.

This so-called "intense" state is his struggle against himself.

Blake's explosive push-off, which relied on neural overtuning, began to show slight fluctuations, while Bolt, thanks to the "neuromuscular feedback mechanism" he had strengthened during his training in the United States, adjusted his power output rhythm in real time.

When he sensed that Blake's stride frequency had dropped slightly, he did not blindly increase the frequency of his push-off. Instead, he slightly adjusted the direction of his push-off through his core, making the reaction force when his feet hit the ground more horizontal, thus increasing the efficiency of each step's extension by 5%.

This "intelligent exertion" is the core takeaway from his scientific training in the United States—with the help of exercise physiology monitoring equipment, he accurately grasps the fatigue threshold of his own muscles and can reserve 10% adjustment space during high-intensity push-offs, avoiding rhythm disorder caused by overactivation of fast-twitch muscle fibers like Blake did.

So the problem is that Blake didn't do well here, entirely because he suffered from a lack of scientific equipment, scientific concepts, and scientific technology compared to Bolt.

At 29 meters, Bolt made a crucial block, pulling Blake out of the lead and immediately taking the top spot.

The anemometer next to the track had a steady needle, indicating a wind speed of about 0.9 meters.

It seems to represent something as well.

Bang bang bang bang bang.

His push-off was no longer a simple "power output," but a comprehensive technical system that integrated "force angle, transmission efficiency, and rhythm control."

The horizontal forward extension of the hip joint during push-off increased by 8 centimeters compared to before training, which is the result of his special training targeting the "stride length bottleneck".

The timing of the ankle push-off is perfectly synchronized with the core twist; each exertion of force is like running according to a pre-set program, precise and efficient. The stability of this technique stems from his extreme pursuit of "movement consistency" during his training in the United States.

Every day on the high-frequency pacing machine, ensure that the force angle and muscle contraction intensity of each step do not deviate too much.

Less is better.

His breathing at this moment is a direct manifestation of the breakthrough in "breathing-core coupling" technology achieved during his training in the United States, and cannot be simply summarized as "a few steps and one breath"—

His breathing is no longer an "additional action" independent of the exertion of force, but rather forms a deep linkage with the core rigidity.

When inhaling, the chest cavity does not expand passively, but rather the transverse abdominis muscle actively contracts, increasing the core tension by 5% at the moment of inhalation. This is equivalent to adding extra reinforcement to the "force transmission support", allowing the reaction force when pushing off the ground to be transmitted more smoothly along the spine.

During exhalation, the rectus abdominis muscles contract naturally, expelling air from the lungs at a steady pace, which coincides perfectly with the rhythm of the hips pushing forward. The end of each exhalation coincides perfectly with the peak of the force exerted during the push-off.

This "breathing-assisted core" design is the result of his repeated calibration using biomechanical sensors during training. In his early years, when his breathing was disordered, his core tension would drop by 10%, leading to increased loss of power when pushing off the ground. Now, through coupled training of breathing and core, this loss has been reduced to less than 5%.

These characteristics propelled him throughout the 30 meters.

So good, so incredibly good, even Mills in the stands...

They couldn't help but nod in agreement.

I never expected to compete back in Jamaica for the first time.

That's how you can achieve such results.

And he wanted to showcase these achievements.

Mills was proud.

But he still admitted it.

I might not be able to do these things myself.

Everything has been made the way it is now.

Even less likely.

More importantly, his breathing rate and stride frequency are "dynamically adapted" rather than in a fixed rhythm.

When running alongside Blake at around 20 meters and needing to briefly increase his power, his breathing cycle will briefly switch from "two steps, one breath" to "three steps, two breaths".

The chest cavity expands less during inhalation to avoid excessive breathing movements that could interfere with core stability.

When overtaking is completed at around 28 meters and the rhythm needs to be maintained, the breathing pattern is quickly returned to the original mode. Through fine adjustments to the breathing rhythm, the "strength and energy supply" are matched in real time. This breathing control ability stems from the mastery of the "phase breathing method" during training.

Adjust the timing and depth of breathing according to the different phases of pushing off the ground, hip thrust, and arm swing to improve oxygen delivery efficiency by 12% compared to conventional breathing methods, ensuring that fast-twitch muscle fibers do not fall into a state of hypoxia during high-intensity exertion.

This is a more scientific and advanced breathing method.

If it's in Jamaica.

Mills had to admit it.

It's true that I can't reach that level.

They had no idea about the technological equipment and theoretical methods for training.

As the head coach, he could see even more clearly how Bolt's breathing "anti-interference" was fully demonstrated during the overtaking process from 20 meters to 30 meters.

Blake's increased force as he pushed off the ground to catch up with the rhythm caused his breathing to become rapid and erratic, while Bolt's breathing remained steady.

His neck and shoulder muscles barely move during breathing, which is achieved through neck core stability training, avoiding unnecessary upper body swaying that wastes energy.

This ability to fully integrate breathing into his technical system is the core hallmark of his transformation from a "purely talented athlete" to a "scientifically trained athlete".

This also gave them a lead at 30 meters.

This is an inevitable result of being overwhelmed by superior technical details.

Bolt actually used details.

It suppressed everyone.

This is simply...

Outrageous.

Even Mills coached Bolt in 2013.

None of them can achieve this level.

Just over 30 meters in, Bolt's mid-race running technique was fully deployed, with breathing control and core, push-off, and hip extension working in a state of "seamless coordination".

Gradually amplify the advantage at 30 meters.

Every step reflects the technical precision honed through training in the United States.

At 32 meters, his breathing and core rigidity formed a "dynamic mutual support." During inhalation, the transverse abdominis muscle no longer simply contracted for reinforcement, but instead used a "wave-like contraction" to cause the chest cavity to sink slightly—

This deliberately designed breathing action can lower the body's center of gravity by 1 centimeter, which is exactly in line with the direction of the horizontal propulsion force when pushing off the ground, theoretically increasing the proportion of the horizontal component of the ground reaction force from 78% at 30 meters to 82%.

At the same time, the external oblique muscles on both sides of the waist and abdomen alternately exert force with the rhythm of breathing. When inhaling to the left, the right external oblique muscles tighten, pulling the left hip forward and horizontally swinging.

During the right exhale, the left external oblique muscle takes over, propelling the right hip forward. The hip extension is stabilized at 18 centimeters, and the trajectory is completely parallel to the ground without any lateral deviation.

This "breathing-driven hip delivery" linkage is the result of his frame-by-frame calibration using a high-speed motion capture device during training, which completely solved the problem of power loss caused by the disconnect between hip delivery and breathing in his early years.

At the 35-meter mark, the ground-pushing technology has been upgraded to a "elastic burst mode".

When the ball of the foot touches the ground, the ankle joint is no longer a rigid support, but rather like it is equipped with an "intelligent buffer device"—it first completes a slight flexion buffer in 0.01 seconds to absorb the ground reaction force, while the calf muscles quickly accumulate elastic potential energy, and then push off at the end of the exhalation, converting the potential energy into forward kinetic energy.

At this point, the range of motion of the knee joint is stable at 148°. This angle is the "golden angle of force" calculated by the biomechanics team based on the length of his muscle fibers. It can ensure the maximum contraction stroke of the quadriceps while avoiding muscle stiffness caused by excessive extension.

It is worth noting that when his heel of the rear leg rises, brushing against the inside of his thigh, it coincides with the start of his inhalation. With the slight relaxation of the core brought about by breathing, the recovery speed of the rear leg is accelerated by 0.02 seconds.

Allow more time for preparation for the next push-off.

At 40 meters, Bolt's arm swing and breathing rhythm were synchronized with "millisecond-level precision".

When the left arm swings back to its limit, it is exactly at the end of the exhale. The scapula naturally retracts as the core contracts during exhale, providing extra assistance for the arm swing.

When you extend your right arm forward to your chest, inhale simultaneously. The expansion of your chest cavity increases the forward swing of your arm by 2 centimeters, but without increasing the burden on your shoulder and back muscles.

This "arm swing leverage breathing" design allows Bolt to control the coordination error between his arm swing frequency and stride frequency within 0.005 seconds, far lower than the 0.012 seconds before training.

Although Blake was trying his best to catch up, his arm swing was already slightly disordered due to rapid breathing.

When Bolt's right arm swings forward, the amplitude varies greatly, and the synchronization with the rhythm of pushing off the ground is significantly reduced. In contrast, Bolt's arm swing is always like a "precisely running pendulum," with each swing calibrating the body's balance and avoiding unnecessary energy consumption.

how come……

The technology is so advanced.

This man.

Is he still the Usain Bolt I remember?

Is that the rough guy with terrible skills?
Of course, this is based on his own opinion, since athletes of Bolt's level should not have such technique.

On this point, he also agreed with Green's previous statement.

But now?

Bolt's breathing depth began to adjust dynamically.

To cope with the oxygen demand brought about by sustained high-intensity exertion, he did not blindly deepen his breathing, but instead increased the oxygen supply by increasing the stability of his breathing rate.

The respiratory cycle was shortened from 0.8 seconds at 30 meters to 0.75 seconds, but the inhalation volume remained consistent each time, ensuring the efficiency of gas exchange in the lungs without disrupting the rigid conduction of the core.

At this moment, his torso leans forward at a stable angle of 33°, with his shoulder line parallel to his hip line. Even during acceleration, his head does not sway at all due to breathing or exertion. This is thanks to the core stability training he has strengthened in his training, which makes his head a "stable visual anchor point" and helps his body accurately perceive the rhythm of the track.

then.

That was what surprised Blake.

50 m.

Bolt, as if he had unlocked the last "physiological shackle," completely released the "breathing-core-power" closed loop he had honed during his training in the United States.

From the 50-meter to the 80-meter 30-meter track, he is no longer limited to "efficient exertion", but pushes his physical functions to a new threshold of human speed through breakthroughs in technology.

He had to prove how fast he could run with every step.

With every step, he maintained the human limit of speed at 46 kilometers per hour!
Bang bang bang bang bang.

Just over 50 meters, Bolt activated his "core resonance" mode, his first "trump card" to break through the top speed barrier.

The core of a regular athlete is a "rigid support," while his core muscle groups undergo "micro-amplitude high-frequency vibration" at an extremely high frequency—the rectus abdominis, external oblique, and erector spinae muscles vibrate synchronously.

This vibration, combined with the ground reaction force generated by the lower limbs pushing off the ground, creates a "resonance effect," which is equivalent to equipping the force transmission with a "super amplifier."

From a biomechanical perspective, in a resonant state, the core's efficiency in transmitting force is no longer "lossless" but rather "gain-conducting".

The 3.2 times body weight reaction force generated by pushing off the ground, after being amplified by core resonance, actually acts on the body as a propulsive force of 3.5 times body weight. This is the first time that humans have achieved "force transmission exceeding 100%" in sports.

This technique is the result of his training using a "low-frequency vibration training device"—

Two hours of resonance adaptation training every day allows the core muscle groups to form a "conditioned reflex resonance," which can automatically match the frequency of pushing off the ground at the moment of rapid start.

Amika is never one to back down.

For so many years, we have been at the forefront of sports technology.

The resonance technology is complemented by "Achilles tendon elastic limit compression".

His Achilles tendon is 3 centimeters longer than that of an average athlete. During training, he uses "progressive load stretching" to increase the elastic potential energy reserve of his Achilles tendon to 1.8 times that of the normal state.

In this way, when the forefoot touches the ground between 50 and 60 meters, the Achilles tendon is like a "carbon fiber spring" compressed to the extreme, completing the energy storage and release within 0.003 seconds, directly converting elastic potential energy into forward propulsive force, and the ankle joint extension speed reaches 1200°/second.

It is 40% faster than the usual top speed.

Completely break free from the limitations of "muscle exertion" and enter a more efficient "elastic drive" mode.

The hip delivery technique is now upgraded to "hip gliding" rather than "swinging".

Using the inertia of core resonance, the hip joint slides horizontally along the body's longitudinal axis, with an amplitude of 23 centimeters, which is 10% greater than the conventional hip extension.

Furthermore, the parallelism error between the sliding trajectory and the ground is less than 0.1°.

This "sliding hip thrust" reduces the vertical fluctuation of the center of gravity to 1.5 centimeters, which is equivalent to the body "translating" close to the ground, reducing air resistance by 15%.

At the 60-meter mark, the instantaneous speed directly exceeded 45.5 km/h, and Blake was already several body lengths ahead.

And he was still performing.

After 60 meters, Bolt's technique entered a state of "adaptation to the limits of human potential," without any surreal or exaggerated design, but rather by refining the core logic of human movement to "millimeter-level precision."

Achieve the "ultimate human capability" in the three dimensions of "neural response, muscle coordination, and motion resistance reduction".

Using "god-like details within a mortal framework".

They were trying to push the speed to the critical point of 46 km/h.

While conventional athletes rely on "adjustment after exertion," Bolt has upgraded this to "anticipatory commands."

His motor cortex sends a "preparatory force signal" to the muscle groups to be involved in the next step 0.012 seconds in advance, based on the force of the previous push-off and the range of hip extension.

For example, the moment the left hip completes its forward thrust, the brain has already instructed the gluteus medius and external oblique muscles around the right hip to enter a "ready state," without waiting for muscle feedback, and directly starts the next round of movement.

This is talent.

It's very difficult to train.

Bolt was born here.

It will be even stronger.

The core of this technology is "deep encoding of motor memory". During training, 10 sets of motion data in the 60-70 meter range were recorded using high-speed cameras. The "optimal motion template for the peak speed range" was extracted through computer analysis. And through 200 sets of "simulated prediction training" every day, the nerves and muscles formed a "conditioned reflex linkage".

At this time, the muscle spindle, the receptor that senses muscle tension, transmits signals 8% faster than regular athletes. It can send force and angle information back to the brain as soon as the muscle enters the exertion state, making the prediction instructions more accurate.

In terms of movement, there is no "gap" in the connection between his hips, knees, and ankles when he exerts force.

At the end of hip extension, the knee joint begins to extend synchronously; at the moment the ankle joint completes the push-off, the pushing leg begins to retract with the aid of the anticipated command.

The entire lower limb movement is like a "seamlessly connected gear set," without the slight hesitation of a regular athlete's "push-pause-re-exert force" motion.

The number of power cycles per second is 0.1 more than the opponent's, a seemingly minor difference.

However, in the extreme speed range, it can be directly converted into a speed gain of 0.3 km/h.

Bang bang bang bang bang.

Bang bang bang bang bang.

Bolt will unleash his super speed here.

He's getting faster and faster.

faster and faster.

faster and faster.

This kind of speed is a despair-inducing speed.

Even someone of Blake Powell's caliber.

Looking at the tall, dark figure ahead.

Everyone feels...

Human speed.

The key was rammed at 46 kilometers per hour.

You've already been...

It's in our hands.

Bolt is like a child returning from overseas.

They are making full use of the skills they have learned.

This game.

It's less of a domestic championship.

It was more like a report meeting by Bolt on his years of training.

And it's quite obvious from the audience's expressions.

He did it.

very successful.

"Eussen rushed out and pulled everyone away at high speed!"

"God doesn't care whether it's Asafa or Yuhan..."

"They are all being pulled apart at high speed!"

"There's no chance left, absolutely no chance!"

"Usain Bolt has secured the championship!"

"Crimping..."

"9.4..."

"9.49!!!!!!!!!!!!!!!!!!!!!"

The commentator was stunned for a moment when he saw the score.

After all, it starts with 9.4.

There have been very few instances of sprinting in human history.

And this time.

It happened at Jamaica's National Stadium.

"Open for 9.50 seconds!!!!!!!!!"

"Jamaica National Stadium's best performance has entered the 9.40+ era!!!!!!!!!"

"A legendary wind speed of 0.9 meters per second!"

"It brought about legendary results!"

"The legendary Black Lightning!"

"We've taken this year's WL from Su's hands again!!!"

"He seems to be proving it!"

Jamaica is the fastest!!!

After Bolt finished running.

I checked the results.

Turning my head, I saw the camera that was already prepared.

grin.

With teeth as white as black toothpaste, he spoke into the camera screen:
"you're right!"

"Su!"

"warm up."

"ended."
