The Su God of the Reopening of the Sports Arena

Chapter 2429 Report: Su Shen says he's going to break the world record in his next match.

The results of the dental championships are in.

Bolt 9.49.

Blake 9.68.

Powell 9.69.

Carter 9.78.

Ashmead 9.91.

Pele 9.97.

……

This level is truly exceptional.

After reviewing the results, they were extremely impressive.

Of course, the biggest problem was Carter; he became the unluckiest guy. And it seems he's always been the unluckiest guy in history.

none of them.

This means he is ineligible to participate in the competition again.

After all, it's either the World Championship title or a Diamond League wildcard.

They are not in Jamaica.

If that's the case...

What needs to be done must be done.

Only three teams can participate in the World Championship.

Carter was also frustrated; he was clearly full of courage...

Why stand still and not move forward?
pity.

Bolt achieved such a terrifying result with this shot.

There's really nothing to say about that.

They're already invincible.

Judging from his appearance, he still has room for maneuver.

Office of the Chinese track and field team.

"How many? 9.49 seconds???" Yu Weili's face darkened upon hearing this result.

It was significantly higher than I had imagined.

He will continue watching this match.

It was discovered that Bolt had never given his all before this.

One thing is a foregone conclusion.

That would put a lot of pressure on you.

After all, you have to think about it, this shot wasn't fired in a particularly strong wind, nor was it taken at a particularly high altitude.

That result is terrifying.

"What did Su Shen say?" Yu Weili asked Yuan Guoqiang.

Su Shen and his team have now returned to China to participate in the competition.

"They said there's no problem."

"He seemed quite calm."

Upon hearing this, Yu Weili felt a little more at ease: "I know Xiao Tian's personality very well. He wouldn't speak without reason. If he says it's okay, then it's highly likely that it is."

"At least Bolt's achievement is now considered reasonable and expected by him."

"To be honest, Lao Yu, I never thought that one day we would be competing with others for the world record in the 100 meters."

“It’s not just you, do you think I could have imagined it?” Yu Weili rolled his eyes and shook his head. “Their generation has developed too fast, so fast that it’s faster than us. If we don’t speed things up, we won’t be able to keep up. We don’t have the experience to help these sprinters challenge the world’s best.”

"Just like the short track speed skating project back then, no one from top to bottom was really prepared."

"We can only proceed cautiously, learning from the experiences of this generation of geniuses."

"Therefore, we must do our job even better."

"We must not let our athletes be distracted when they are competing in major events."

"By the way, did Xiao Tian say how the selection competition is going to be held this time?"

"I told you, it's in Qing Tang City."

"Qingtang City?" Yu Weili was taken aback. That place was over 2200 meters above sea level, so Su Shen's actions must have some other meaning...

"Could it be that he wants to stay here?"

"That's right, he wants to break the world record here."

Yuan Guoqiang seemed to be getting excited as well, saying, "It's not just about surpassing Bolt's 9.49 seconds."

"And he's going to set a record here that Bolt can't achieve."

"He's going to break the world record."

"it is good!"

As Yu Weili listened, he couldn't help but pat the table in front of him. Who among athletes doesn't have a burning passion?
In those earlier years, there was no way to make these retired athletes stand up for themselves.

Now it actually exists.

I definitely don't want to miss it.

"Then what are we waiting for? Let's hurry up and ask the higher-ups to approve it. If it's not approved, I'll go directly to Instructor Feng. I believe that as long as I tell him what Xiao Tian is planning to do..."

"He's probably even more excited than we are."

These words...

That's absolutely right.

Upon hearing this, Feng Shuyong learned that Su Shenjing was preparing to strive for the highest score in this selection competition.

That really got me going.

Make a call immediately and give specific instructions and reminders.

Ask the staff at Qing Tang City to help immediately.

We must bring out our best preparation state.

Give athletes the most comfortable rest and competition time.

Since the goal is to break the world record.

Nothing can be missing.

"Oh, right."

Feng Shuyong thought for a moment and exclaimed in surprise, "How could I have forgotten this?"

Then he immediately spoke.

"Quickly go and check the windshield."

Qingtang City is a new stadium built later with investment from Su Shen and funding from other countries, so it naturally has all these things.

If others have something that helps you achieve results, we should have it too.

After all, many casual track and field fans don't understand these things.

I don't understand anything about wind or not.

They only care about grades.

So when they saw that Xiao Rizi's results were better, they thought we had no chance.

In fact, when they collide head-on.

You'll find that even if they're tough and stronger than us, they're a level, two levels, or even three or four levels above us...

It's possible that they would lose even in a head-on confrontation.

That's just how outrageous it is.

Otherwise, the names "Big Shrimp" and "Soft-legged Shrimp" wouldn't exist in international track and field events...

So loud.

"Xiao Tian." After finishing these tasks and giving instructions, Feng Shuyong looked at a group photo hanging on the right side of his desk.

The image above is of myself, Su Shen, and Feng Shuyong.

That was when Su Shen helped a person of Asian descent win the world's first gold medal in a sprint event in Daegu, and they took a group photo to commemorate the occasion.

For most ordinary track and field fans, the gold medals from the 2012 London Olympics are definitely more well-known and have greater significance.

But for Toyoki Isamu...

This gold medal at the Daegu World Championships is just the beginning; this is the gold medal we've been looking for.

That was the first step in breaking the psychological shackles of race.

……

China Sports Channel.

"Hello, viewers. This is China Sports Channel."

"I am your old friend Yang Jian."

"This competition is the site of our country's track and field selection trials."

"The World Championships in Beijing are about to begin, and there are still more than two months to go. The athletes are all eager to compete."

"This competition is a major battle to secure a place in the next round."

"If you don't perform well, your position may be taken by someone else."

"This is the last time we'll play at home in the last 10 years."

"Right now, I just want to see our athletes perform well and give it their all in the Bird's Nest stadium."

"I believe everyone will give their all in this selection competition. Otherwise, if we can't stand on the Bird's Nest in August, it will definitely be the biggest regret of our careers."

After Yang Jian finished speaking, the match was about to begin.

"The special significance of this event lies first and foremost in the completely new look of the venue itself. To meet World Championship standards, the Qing Tang City Stadium not only relaid its 'lychee-patterned' running track, making it softer to the touch and technologically advanced, but also added two giant screens to the east grandstand, forming a six-screen联动 (interconnected) system with the relocated north and south screens, achieving a 'no blind spots' viewing experience. At the same time, the sound and lighting systems have been fully upgraded, and the newly built 6300-kilowatt substation in the south square further ensures the broadcasting needs of the event. 'The track has excellent elasticity, making it very comfortable and easy to run on,' the participants' comments confirm the effectiveness of the venue renovation."

"Why do we do this? Because this type of runway will also be used in the Bird's Nest."

"Let the athletes warm up the crowd in advance."

"Familiarize yourself with the operation of the runway."

"Lychee-patterned" running track is a high-performance plastic running track named for its irregular texture resembling lychee peel, and it possesses a variety of advanced characteristics.

The World Championships in Beijing adopted this format.

It is usually a hierarchical structure.

The upper layer is a high-toughness, wear-resistant rubber surface layer, which is composed of irregular lychee patterns formed by continuous calendering by extrusion equipment, providing excellent wear resistance and sufficient sole friction.

The lower layer is a highly elastic bottom layer, which is generally a regular grooved air cushion structure to ensure high resilience performance, provide good shock absorption capacity, smooth energy transition and continuous energy feedback.

Lychee-patterned running tracks use natural materials, such as EPDM synthetic rubber, which is 100% recyclable. Others use water-based EAU sulfur-free and odorless materials, which have ultra-low VOCs and are free of MDI, TDI, and soluble heavy metals, meeting relevant environmental protection standards and being more friendly to human health and the environment.

Its athletic performance is also excellent.

The lychee-textured surface design increases the friction coefficient of the track surface, providing athletes with better grip and helping to improve their performance, while also reducing the risk of athletes slipping during running.

Furthermore, the track's elasticity and cushioning properties effectively reduce the impact on athletes' joints and muscles, lowering the probability of sports injuries.

Lychee-patterned running tracks are permeable. For example, the water-based EAU sulfur-free odorless sponge-type lychee-patterned court surface has a permeability of up to 3.0mm/s, which can quickly drain rainwater, keeping the field dry and ensuring that athletes can compete safely in all kinds of weather conditions.

The prefabricated lychee-patterned running track also features a bottom layer with a grooved air cushion structure.

This forms numerous sealed air sacs.

When an athlete's foot strikes the track surface, these airbags compress to absorb the impact and vibration, converting kinetic energy into stored energy, which is then fed back to the athlete.

The benefit of long-distance running is reduced fatigue:

The elasticity and energy feedback characteristics of the running track can reduce the fatigue caused by ground reaction force during long-distance running, enabling athletes to maintain a more stable running rhythm and extend the exercise time and distance.

And it provides stable support:
Because of its high flatness and moderate elasticity, the lychee-patterned running track can provide stable support for long-distance runners, reducing body swaying and extra energy consumption caused by uneven ground or uneven elasticity during running, and helping athletes maintain good running posture and athletic performance.

If there are benefits for long-distance running, then there must be equally benefits for sprinting.

Firstly, it can improve starting and acceleration efficiency:
The high coefficient of friction of the lychee-patterned running track provides better grip for sprinters, allowing them to push off the ground more effectively during starts and acceleration, reducing power loss and thus improving the efficiency of starts and acceleration.

Secondly, it can reduce joint impact:

Its excellent elasticity and cushioning properties can effectively absorb the impact generated during sprinting, reduce damage to joints and muscles, and allow athletes to focus more on the competition and perform at a better level.

Furthermore, the hexagonal surface structure of the lychee-patterned track, resembling a honeycomb, allows for rapid recovery upon impact, providing athletes with a stable and continuous elastic experience. Its directional compression makes the track more resilient and responsive, and also provides better lateral support, thus offering better control during foot rolling movements.

Solvent-free polyurethane materials.

Thermoplastic polyurethane (TPU) material.

Self-texturing technology.

They are all outstanding.

Not to mention that, theoretically, it can also improve starting explosiveness:

Because of the high coefficient of friction of the lychee-patterned surface, sprinters can make their feet fit tightly against the track when they push off at the start, reducing slippage and converting leg power into forward kinetic energy more efficiently, thus helping them to get off to a quick start.

Optimize efficiency during the acceleration phase:
The airbag structure in the elastic bottom layer of the track can accurately feed back energy based on the force of the foot landing during acceleration, avoiding energy loss and helping athletes reach their maximum speed faster.

Enhance sprint stability:
During the sprint phase, athletes lean forward significantly, and the irregular texture of the lychee pattern provides multi-directional grip, preventing foot slippage and ensuring a smooth and stable sprint.

Reduce muscle tremor expenditure:
The damping properties of the track can suppress muscle tremors when the foot lands, reduce unnecessary energy consumption, and allow sprinters to maintain muscle strength concentration throughout the race.

Provides precise foot control:

The subtle textured surface of the lychee pattern enhances the contact between the foot and the track, helping athletes to better perceive their landing position, adjust their stride frequency and length, and optimize their running rhythm.

Adapting to sprint spike requirements:
The size of the texture gaps is precisely designed to perfectly accommodate the spikes of sprint shoes, preventing the spikes from getting stuck and enhancing the push-off effect through the interlocking of the spikes and the texture.

……

Especially the last point.

Su Shen Labs has developed a brand new pair of spikes specifically for the track at this year's World Championships in Beijing.

In terms of quantity and arrangement, for straight-track sprints, an eight-stud design is adopted, with the studs concentrated on the outer edge of the forefoot, such as three in the middle of the forefoot, two on each side, and one on the heel, to increase the stability and grip of the foot and help athletes generate more power during the start and acceleration.

For sprint events with curves, such as the 200-meter and 400-meter races, a seven- or six-stud design can be considered, with the forefoot stud distribution adjusted to suit the needs of turning.

As a high-end representative of current track and field venues, the lychee-patterned track, with its three-dimensional characteristics of "high-friction texture + elastic cushioning structure + high-tech material base", puts forward the core requirements of "precise bite, efficient force transmission, synergistic cushioning, and dynamic adaptation" for sprint spikes.

Sprint events revolve around a core rhythm of "explosive start - rapid acceleration - high-speed maintenance - stable finish," and the functional requirements for spikes differ at each stage:
The starting phase requires maximum grip and power transfer.

The acceleration phase requires dynamic support and energy feedback.

At high speeds, a balance between lightweight design and stability is required.

Precise control and safety assurance are required during the final sprint phase.

Therefore, the design of specialized spikes must be based on the physical characteristics of the lychee-patterned track and follow the biomechanical laws of sprinting to achieve dynamic synergy among the track, spikes, and athlete, ultimately achieving the dual goals of "improving athletic performance and reducing the risk of injury".

The special design requires the use of titanium alloy composite ceramic material, which combines the high strength of titanium alloy with the high wear resistance of ceramic through powder metallurgy technology to form a double-layer structure of "rigid core + flexible coating".

The rigid core (75% titanium alloy) ensures that the spikes penetrate the lychee-patterned surface and embed into the gaps in the texture when the foot strikes the ground; the flexible coating (25% zirconia ceramic) can produce micro-elastic deformation when in contact with the track, increasing the contact area with the textured protrusions, while avoiding scratch damage to the track surface from hard materials.

For example, the batch that Suarez distributed to the top athletes is a typical example, mainly for sprinters.

To address the irregular texture of the lychee-patterned running track, the shape of the spikes needs to break away from the traditional single design of conical and cylindrical shapes, and adopt a "triangular bionic anchor" structure.

The spike head is in the shape of a triangular pyramid, with the three edges being blunted to ensure both the ability to penetrate the gaps in the texture and to prevent sharp edges from cutting the surface of the track.

The spikes feature a spiral groove structure in the middle, similar to the barbs of an anchor. When the spikes are embedded in the track, the spiral grooves can mechanically engage with the raised texture of the lychee pattern, enhancing lateral anti-slip force.

The bottom of the spike has a hemispherical transition, and the connection with the sole is rounded to reduce stress concentration and prevent the spike from breaking during high-intensity stomping.

In addition, to meet the needs of different stages of sprinting, the edge angle of the forefoot lateral spike can be finely adjusted to 15° to enhance lateral grip when pushing off the ground in corners.

The angle of the spike edge on the inner side of the forefoot is maintained at 20° to optimize the forward force transmission efficiency during straight-line acceleration.

The elastic layer of a lychee-patterned running track is typically 10-15mm thick, so the length of the spikes must be strictly controlled within a range that allows them to embed into the elastic layer without touching the rigid base. After extensive biomechanical testing, 4.5mm to 5.5mm spikes have been found to be the optimal choice.

This length allows the spikes to penetrate approximately 2mm of the abrasion layer on the surface of the track and approximately 2.5mm into the elastic layer. This allows for energy feedback through the compression deformation of the elastic layer while avoiding a sudden increase in impact force caused by the spikes touching the underlying rigid structure.

If the spikes are too short, such as 3mm, they can only fit against the surface of the track and cannot form an effective bite, making it easy to slip at the start; if they are too long, such as 6mm, they will penetrate the elastic layer and directly contact the rigid base, not only losing cushioning protection, but also increasing the risk of ankle sprains due to the hard collision between the spikes and the base.

Meanwhile, the spikes feature a "gradient design," with slightly shorter spikes on the inner forefoot and slightly longer spikes on the outer forefoot. This design adapts to the uneven force distribution on the inner and outer sides of the foot during sprinting, improving landing stability.

The stud layout is based on dynamic optimization of pressure distribution.

Based on the pressure distribution data of the soles of the feet during sprinting.

At the start, the pressure on the outer forefoot reaches 2000N/cm, and the peak pressure on the middle forefoot during acceleration is 1800N/cm. The spike layout adopts an asymmetrical structure of "dense core force area + sparse auxiliary support area".

A total of 8 studs are set in the forefoot area, with 5 studs arranged in a "fan shape" in the core stress area, the middle and outer sides of the forefoot.

The three cleats in the middle of the forefoot are spaced 8mm apart, forming a stable triangular structure that bears the main task of forward force transmission.

The two cleats on the outer forefoot are spaced 10mm apart and angled outwards at a 5° angle to enhance lateral support. (Auxiliary support area.)

The inner side of the forefoot and the toes.

Three spikes are arranged in a straight line with a spacing of 12mm, mainly to balance the force on the foot and prevent lateral rollover. There are no spikes in the heel area, only an elastic cushioning pad, because the heel hardly touches the ground during sprinting, and extra spikes are avoided to prevent adding weight and affecting the continuity of movement.

In addition, the connection between the spikes and the sole adopts a "rotational locking structure," allowing athletes to change to different sizes of spikes according to their own foot shape and track conditions, thus improving the adaptability and flexibility of the spikes.

The sole of the shoe further constructs an energy cycle mechanism of "force transmission-buffering-feedback".

The sole is a key component connecting the spikes and the upper. It needs to meet the dual requirements of "efficient force transmission" and "coordinated cushioning" to form "dual elastic feedback" with the elastic base of the lychee-patterned running track, minimizing energy loss and improving sports efficiency.

Su Shen's shoes are in a striking red color scheme.

It is manufactured using a three-layer structure.

level one.

Top layer (connecting layer with the spikes): Made of high-strength carbon fiber composite material with a thickness of 1.2mm. This material has an elastic modulus of 230GPa, which ensures that the force of the spikes when pushing off the ground is quickly transmitted to the entire foot, avoiding energy loss caused by sole deformation.

At the same time, the surface is "micro-roughened" to increase the friction with the locking structure of the shoe spikes and prevent the shoe spikes from loosening during high-intensity sports.

Second floor.

Middle layer (buffered feedback layer): Made of a new type of TPU (thermoplastic polyurethane) foam material, prepared through supercritical foaming technology, with a density of only 0.18 g/cm and a thickness of 3 mm. This material has a resilience rate of 75%, which can form a "double buffer" with the elastic layer of the lychee-patterned running track.

When the foot lands, the mid-layer TPU foam material first absorbs part of the impact force, and the remaining impact force is transferred to the track elastic layer. Then, the rebound force is reflected onto the sole through the track, and the mid-layer material further amplifies this rebound effect, forming a "secondary energy feedback".

Tests have shown that this structure can improve energy feedback efficiency by 20%, helping athletes gain additional forward momentum when pushing off the ground.

the third floor.

The bottom layer (connecting layer with the upper) is made of glass fiber reinforced nylon with a thickness of 0.8mm. This material has good rigidity and bending resistance, which can prevent the sole from deforming excessively when the foot bends, while its weight is only 60% of that of traditional nylon materials, effectively reducing the overall weight of the spiked shoe.

The bottom surface is designed with "mesh-like grooves" to enhance the adhesion to the upper and prevent the sole from separating from the upper during exercise.

The sole is based on the arch shape of sprinters and the deformation pattern of the foot during exercise. The sole structure adopts a "bionic arch support + dynamic bending groove" design.

Arch support area:
A titanium alloy memory foam insert is embedded in the arch of the foot. The insert is 0.5mm thick and 15mm wide, and is curved to fit the arch curve. This insert has the characteristics of "deforming upon impact and rebounding upon impact".

When an athlete accelerates, the arch of the foot bears a large tension, and the shrapnel deforms slightly to distribute the pressure on the arch.

When the foot pushes off the ground, the spring quickly rebounds, providing upward support to the arch of the foot, helping the foot to quickly return to its natural shape and reducing arch fatigue.

Meanwhile, the surface of the spring is wrapped with a layer of flexible silicone to enhance its fit to the sole of the foot and improve wearing comfort.

Forefoot flexion area:
A radial flexing groove is designed at the corresponding position of the forefoot and metatarsophalangeal joint. The groove is 1.5mm deep and 2mm wide, with a total of 6 grooves, extending radially from the base of the toes to the edge of the forefoot. This design allows the forefoot to flex flexively during push-off and landing, adapting to the natural flexion and extension movements of the foot during sprinting and reducing the restriction of toe movement by the sole.

The bending groove is filled with flexible TPU material to prevent foreign objects from entering the groove and affecting the performance of the sole, while also enhancing the wear resistance of the bending groove.

Heel stabilization zone: The heel area adopts a "10° upward arc design" and adds a "triangular stabilizing plate" on the outside. The stabilizing plate is made of carbon fiber composite material and is 1mm thick.

This design allows the heel to remain slightly off the ground throughout the running process, which aligns with the "forefoot strike" technique in sprinting. At the same time, the stabilizer effectively prevents the foot from rolling outward upon landing, reducing the risk of ankle sprains.

Then there's the sole.

Although cleats are the primary source of grip.

However, the pattern design on the sole surface can further enhance the compatibility with the lychee pattern track. The sole surface adopts a "diamond interlaced pattern" with a pattern depth of 0.8mm and a pattern spacing of 3mm.

The sharp angles of the diamond pattern can be embedded in the small gaps of the lychee pattern, increasing the contact area between the sole and the track.

The staggered structure creates "multi-directional grip," providing stable support through the interlocking of the grooves regardless of the direction of force applied to the foot.

In addition, shoe lasts.

This is the "skeleton" of the spikes, which directly determines the shape and comfort of the spikes. It needs to be designed based on the foot shape data of sprinters and the laws of sports biomechanics to achieve a high degree of fit between the "last, foot shape, and movement".

Shoe last length —

Based on the athlete's actual foot length, an 8mm margin is added to ensure sufficient room for toe movement while preventing the foot from sliding inside the shoe due to an excessively long last. Additionally, the forefoot features a tapered design with a 10% reduction from the base of the toes to the toe box, conforming to the natural alignment of the toes.

Shoe last width – the forefoot width is divided into three specifications based on foot shape data: narrow, standard, and wide. The narrow version is 85mm wide, the standard version is 90mm wide, and the wide version is 95mm wide, to meet the needs of athletes with different foot shapes.

The width of the mid-section of the shoe last is 10% narrower than the forefoot, forming a "waist-cinching design" to enhance support for the arch of the foot and prevent the foot from turning outward during exercise.

Shoe last height – forefoot height is 25mm, and arch height is divided into three levels: high, medium, and low, depending on the arch type.

High arch 20mm, medium arch 15mm, low arch 10mm.

The shoe features replaceable arch support pads to accommodate different arch heights. The 30mm heel height of the last incorporates a concave design to conform to the heel shape and enhance heel stability.

……

Tell me about it.

With such detailed and targeted reinforcement.

Why are we always able to perform better in major competitions?

Competitive sports training is definitely not just about the individual efforts of athletes.

If you think that way, you are completely wrong.

A true powerhouse in sports is strong in every aspect.

All of these things added together.

That is the foundation upon which strong athletes are constantly emerging and records are constantly being broken...

Su Shen always provides players with appropriate combat boots for each major competition.

This has basically become the norm.

Many people are not used to changing their shoes often at first, and feel that it might be too extravagant.
But in fact, they only realized this after they got used to it.

Compared to the ability to produce results.

There are these shoes.

Definitely worth it.

However, if they knew the cost of these R&D efforts, and if Su Shen hadn't known the runway characteristics in advance for point-to-point runway adaptation...

Even if you've developed some high-tech shoes.

Your compatibility.

In this competition.

It's definitely not as good as the Su Shen system.

Su Shen can absolutely guarantee that.

I didn't start over for nothing.

Looking at the plateau terrain I've stepped onto once again.

They even hung up their own giant portraits on the plateau site in advance.

If only your eyes were a little sharper.

You're more likely to notice.

There are also quite a few atmosphere-enhancing props prepared.

All of these procedures were carried out, with tickets distributed accordingly.
