The Su God of the Reopening of the Sports Arena

Chapter 2519 The True God Descends! A true god grows stronger the more you analyze.

"Let's look at another god."

Green was very direct.

At this level, it's impossible not to call him a god.

After all, wasn't Bolt just a god of the late stages?

This time, Green didn't keep anyone in suspense.

All of Su Shen's data was released very quickly.

0.106 1.63 2.61 3.52 4.38 5.24 6.07
This is the segmentation of the future.

The later stages are—

6.91 7.74 8.60 9.49.

The final segment is 6.07 + 3.42.

Compared to Moscow, your chances of improvement are 0.01 in the early stages and an even more terrifying 0.05 in the later stages!

Keep in mind that the wind speed here is even greater, with headwinds reaching half a meter.

This means that not only does it improve one's chances of a bright future, but it also enhances one's overall strength.

Moreover, despite running so fast throughout the race, he made another surge in the later stages, and even leveled up.

Don't be fooled by the fact that this shot only took 3.42 seconds; it's the result of running another new human record in 3.42 seconds.

This is actually quite similar to Bolt's shot.

This means that after achieving a run that was almost as good as, or even better than, Moscow's, he had a huge burst of success in the later stages.

It can run even faster in the later stages.

If this shot hadn't been fired with that half-meter headwind...

Green can say with certainty that he can open the second half with a time of 3.40 seconds.

If he can break 6.10 seconds in the first half of the race, he's probably the only one in human history to break 3.40 seconds in the second half.

It's just a pity that the weather didn't cooperate.

A strong headwind kept him out of the 3.40-second mark.

Despite such exertion, he was still able to run 3.42 seconds in the later stages.

That's pretty terrifying.

0.106 1.63 2.61 3.52 4.38 5.24 6.07 6.91 7.74 8.60 9.49.

Let's take a look at the final segmentation.

You will then be able to understand it.

That's absolutely terrifying.

1.63 0.98 0.91 0.86 0.86 0.83 0.84 0.83 0.86 0.89.

Compare Moscow's 1.04, 2.62, 3.53, 4.39, 5.25, 6.08, 6.92, 7.80, 8.67, and 9.55.

Ten-meter segments:

1.64, 0.98, 0.91, 0.86, 0.86, 0.83, 0.84, 0.88, 0.87, 0.88.

"With a bent-arm start and a closed-loop technique throughout the entire 60-meter race, the 60-meter race is amazing because it pushes the biomechanical efficiency of the sprint to the limit of human capabilities. There are no weaknesses or loss of power throughout the entire race, and every step is taken at the optimal solution for power generation."

"This is a complete and utter crushing victory over the world's top athletes of the same period, and a revolutionary breakthrough for Asians in the future of human sprinting!"

"A bent-arm start determines the outcome; a crushing advantage is established in the first 10 meters."

"The bent-arm support and push-off are the foundation of this 60-meter dash, not an isolated movement. The bent arm forms elastic support at the moment of push-off, and the reaction force of the upper limb and the push-off force of the lower limb form a combined force in the same direction, which is fully converted into forward power without being wasted upward. At the same time, it locks the core and low center of gravity, prevents the torso from swaying and losing power, and ensures that the starting explosive force is 100% landed. This gives you a head start over straight-arm starters—while others are still adjusting their center of gravity and wasting energy, he has already used the combined force to move forward at full speed, establishing an advantage in the first 10 meters. More importantly, this starting posture allows the neuromuscular recruitment to be fully activated instantly, laying the groundwork for a seamless power rhythm for the subsequent acceleration. This is the foundation for achieving the best results in the 60 meters. Without this technical foundation, no matter how strong you are later, it will be difficult to reach the top level."

"You can tell how useful this technique is by looking at how Bolt uses it now. However, it will be quite difficult to promote. After all, I have asked many athletes, and mastering this technique is not easy. Moreover, in a competition, due to tension, it is easy to make mistakes if you have to exert force in multiple dimensions."

"But he created this technique himself. As the founder, there is no problem with that. Moreover, I think he has been improving and refining the specific details of the technique. In fact, I think he has been fine-tuning it. But as for the specifics, I am not a sports science researcher. The deeper principles would have to be left to the professionals in the laboratory."

"But in terms of technical maneuvers..."

"I think he did a very good job."

"Of course, I can't say anything else besides 'good'."

"I can only say that if I had this technology back then, I would definitely have had the opportunity to reach higher dimensions. At least becoming a giant would have been a piece of cake."

After finishing his sentence, Green said, "The 10-30 meter acceleration is seamless, turning the advantage of the start into an absolute speed advantage."

"After unlocking the first 10 meters of bent-arm support, no adjustments are needed to directly enter acceleration mode. The core is the seamless connection between the taut shoulder girdle and core muscles at the start to accelerate power without any rhythmic breaks. During acceleration, the torso leans forward gradually, without standing up too early or suddenly raising the head, always maintaining a forward force component. Combined with hip drive to drive a coordinated increase in stride frequency and stride length, the foot cushioning upon landing is extremely short, and the power is generated at the moment of push-off. The kinetic energy of each step is completely transferred to the next step, focusing solely on acceleration without any loss of power. Most athletes either lose speed here due to poor start-up transitions or waste power due to loss of center of gravity, but he relied on the rhythm foundation established at the start to make the acceleration slope increase sharply, and the speed soared without any interruption, completely amplifying the advantage in the first 10 meters. By the 30-meter mark, he was already preparing to challenge the maximum speed threshold, laying the groundwork for a stable pace in the middle of the race."

"There's a detail here. You can see that his center of gravity is extremely low. Usually, with such low pressure, there would have been a problem long ago, but he didn't. So, we can only say that he has mastered some new skill. Judging from his center of gravity, his forward momentum and acceleration zone will be extended."

"At least that's how I see it. You know, I don't have the ability to talk about scientific research principles in front of Su, a leader in sports research."

"I can only speak of the appearances I can see."

"Yes, what this netizen said in the live stream is absolutely right, just say it's awesome."

"The section from 30 meters to over 60 meters is even more impressive," Green said. "Because he maintains his initial center of gravity after 30 meters, and for an even longer time, even up to 40 meters, he seems to have combined the acceleration and mid-race zones into a single start. I don't know how he does it, but I can say that this allows his center of gravity to remain low and slowly rise after 30 meters, with an even slower rise, thus extending the combined acceleration and mid-race zone. This is the core key to achieving continuous acceleration from 30 to 50 meters and a precise cut to top speed at 50 meters."

"The extended mixed running zone allows for buffering and continuation of speed increases, eliminating the need for forced acceleration that could disrupt the rhythm. Relying on the forward momentum built up by a low center of gravity, one can maintain a steady top speed from 30 to 50 meters, with each step adding kinetic energy. The low center of gravity keeps the head stable, the torso steady and unwavering, and the core rigidity is maintained throughout, minimizing energy consumption. Even as the speed increases, the power delivery rhythm remains intact. When entering the top speed zone at the 50-meter preparation stage, the center of gravity is not raised to the optimal height for normal running, yet the transition is seamless, and one can still maintain a stable posture and not lose power after entering the zone."

"The most ruthless part of this 60-meter race is not the initial sprint to maximum speed, but rather the strict adherence to the 6-second rule for the initial stage, the continuous peak speed increase from 30 to 50 meters, the precise entry into the highest speed zone at 50 meters, and the stable peak speed at 60 meters without any decline. The speed curve shows no drop at all throughout the entire race. This is the key to crushing the world's top athletes."

"The core foundation is still the complete continuation of the previous technology. The core rigidity and power rhythm established from the start of the curved arm run have been maintained without interruption throughout the entire process, which supports this perfect speed advancement."

"The core rigidity locked in by the bent-arm start is maintained throughout the entire race. After 30 meters, the torso remains as stable as a rock. At high speed, there is no swaying from side to side or up and down. Every bit of force is precisely converted into forward power without any internal friction. In the 30-50 meter stage, the hip drive intensity continues to increase, the thigh folding range gradually increases as the center of gravity rises, the stride length steadily expands but the stride frequency remains high. We do not do the foolish thing of sacrificing stride frequency for stride length. Relying on the ultimate coordination of hip, knee and ankle push-off and swing, the speed continues to climb. Each step is faster than the previous one, steadily moving towards the highest speed zone."

"The worst thing to do at this stage is to exert too much force, which will disrupt the rhythm. Su, on the other hand, relied on the rhythm of exerting force that he established from the start, and progressed step by step without being flustered or chaotic."

"He cut into the top speed zone precisely at 50 meters, which is the optimal point under the 6-second rule. If he cuts in too early, he is likely to lose power prematurely, and if he cuts in too late, it is difficult to reach full speed before 60 meters. He just happened to step into this golden point. After cutting in, he immediately entered the 'top speed stable control' mode. The amplitude and frequency of the hip push and swing were completely fixed, forming an automatic power generation closed loop. He could maintain the optimal ratio without deliberate adjustment and would not deform his movements when he just entered the top speed. At the same time, the breathing and power generation rhythm that was adapted throughout the entire process was completely stabilized. Aerobic energy supply was used as a backup, and anaerobic energy supply was used as a boost. The connection was seamless and without gaps. Unlike other athletes in the early stages of the race, he did not easily drop in speed due to fluctuations in physical fitness."

"What's even more terrifying is that most top athletes experience a slight drop in power after reaching their top speed at 50 meters, with even a 0.01-second decline being common. However, Su, relying on the technical momentum from his bent-arm start and the acceleration from 10 to 30 meters, was able to maintain his power intensity after reaching his top speed, and remained firmly locked at his peak speed at 60 meters, without any decline whatsoever..."

"You might even witness things defying the laws of physics!"

"In the race, it's not difficult to accelerate continuously from 30 to 50 meters, but it's difficult to maintain the rhythm during acceleration; it's not difficult to reach the top speed from 50 meters, but it's difficult to maintain the speed after reaching the top without losing momentum. He mastered both of these challenges to the extreme. From 30 to 60 meters, he didn't rush to the top in one go, but rather he steadily climbed up step by step, made precise entry, and maintained stable control at the peak. His speed curve rose all the way up to 60 meters, which is the most amazing part of those 60 meters. Others either accelerate to a stop or lose power after slowing down, but he was flawless throughout, with every step perfectly timed to the optimal rhythm of the 6-second rule."

"This is the real ceiling for human potential."

"This shows that he has completely mastered the rhythm of the first 60 meters."

"Let's compare it to Moscow."

"Because the data from the Bird's Nest this year is actually very similar to the data from Moscow, a comparison can provide a more intuitive understanding of the Soviet Union's progress and changes."

"First look at hard power: a slight difference can make all the difference."

Green tapped the screen, and two sets of contrasting animated images appeared.

These are comparison photos taken this year at the Bird's Nest and two years ago in Moscow.

“看起来这两届前60米分段数据高度重合，莫斯科分段1.64、0.98、0.91、0.86、0.86、0.83，总用时6.08秒；鸟巢分段1.63、0.98、0.91、0.86、0.86、0.83，总用时6.07秒，单看数字只差0.01秒总用时、0.01秒前10米，看似微不足道，实则是……前程跑“从有瑕疵到无破绽”的跨越。”

"This slight advantage, when placed on a world-class stage, is an overwhelming gap and a direct manifestation of the ultimate refinement of technique. The Moscow cycle was already the best in the world, while the Bird's Nest cycle was the real ceiling of human potential. The ability to run almost the same segments with a deterrent force that opponents can only dream of is due to the upgrade of the core technology."

"I'll offer some preliminary analysis, hoping that Sue can provide some guidance on my remarks after seeing them." Green was very humble in front of Sue, completely different from when he was instructing Bolt.

This is not only because Su Shen is his boss and has outstanding personal abilities, but also because of his achievements in this profession, which are truly convincing.

Alika is the most superstitious about authority.

Moreover, all these identities are combined into one person.

You can't succeed without being authoritative or superstitious.

"I believe the most fundamental improvement is rooted in the starting line, which is the foundation of a promising future."

"During the 2013 Moscow cycle, Su had already mastered the core framework of the flexed arm start, reaching a stage where he was 'using it well' and proficient in it. His technical movements met the standards but had not yet reached the essence, leaving room for optimization. In the 2015 Bird's Nest cycle, he completely honed the flexed arm start technique to perfection, making it an instinctive skill. He achieved zero delay, zero internal friction, and maximum combined force during the start. This millisecond-level and micrometer-level improvement became the core source of confidence in widening the gap in the first 60 meters and was a key leap from 'world-class start' to 'the ceiling of human starting ability'."

"It belongs to the concept of the god of use."

"The 2013 Moscow cycle's bent-arm 2.0 was already a mature technique that overturned the traditional understanding of starting. It had long since abandoned the drawbacks of excessive elbow joint rigidity, upward impact of reaction force on the torso, and serious waste of power when using straight-arm support. It also got rid of the superficial problem of the bent-arm 1.0 stage, which only pursued posture and ignored force transmission. It truly built the core logic of "bent-arm support reaction force + lower limb push-off force" in the same direction, successfully reducing the waste of vertical force to a low level, and enabling a qualitative leap in starting explosive power, which was enough to support him to run at the top human level in the Moscow World Championships."

"However, the 2.0 version of the bent arm at that time still had subtle flaws that were difficult to see with the naked eye but determined the upper limit of force. These shortcomings seemed insignificant, but they became the key to restricting the starting efficiency from reaching its limit. The first is the control of the elbow joint angle in the bent arm support. Although the 2.0 version of the bent arm has clearly defined the core requirement of acute angle support and can be stably controlled within the appropriate range, it has not achieved precise locking. Instead, it is in a relatively reasonable floating range. Each time you squat and prepare, the angle will fluctuate slightly by 0.5-1 degree. This seemingly negligible deviation directly leads to the shoulder girdle muscle group's force fulcrum not being able to form an absolutely stable state. It is difficult to build a completely rigid support surface when supporting, which in turn causes a slight deviation in the transmission path of the upper limb reaction force. It cannot achieve 100% synchronization with the forward push force of the lower limb hip, knee and ankle. There is always a very small amount of reaction force diverted into vertical or lateral components, causing hidden loss of the combined force. This is the core problem that the 2.0 version of the bent arm has never been able to maximize the combined force."

"Secondly, there is a millisecond-level delay in the connection between the shoulder girdle muscles and the core muscles. In the 2.0 stage of the flexed arm exercise, although Su can achieve synchronous tension of the shoulder girdle and the core, this synchronization still relies on the active control of the nervous system. Essentially, the shoulder girdle is triggered to tighten first, and then the core quickly follows up and locks in. This extremely short delay prevents the torso from instantly forming a rigid whole. After the force of the lower limbs pushing off the ground is transmitted from the soles of the feet to the hips, there will be a slight unloading at the connection between the core and the shoulder girdle, which cannot achieve seamless transmission of power. As a result, the starting explosive force cannot be fully released, leaving a slight redundancy in the force exertion."

"Furthermore, while the lowered center of gravity of the 2.0-speed sprinter has been achieved and the logic of adapting the low center of gravity to the sprinter's support has been clearly defined, the adaptation between the two remains at a basic level. The forward tilt angle of the center of gravity and the support point of the sprinter's support do not correspond precisely, failing to form a deep mechanical fit. This results in head stability relying on deliberate posture control, and the moment of starting power generation being affected by instinctive reactions, occasionally showing slight head tilt. Once head tilted, it will cause a slight adjustment in the forward tilt angle of the torso, resulting in a slight backward shift of the center of gravity, further diminishing the forward momentum and inertia. This makes the starting power generation always fall short of the final push, unable to break through the efficiency ceiling of the 2.0-speed sprinter's support. In short, the 2.0-speed sprinter's support during the Moscow cycle is 'technically mature and skillfully applied,' with power generation efficiency reaching world-class levels. However, there is still room for optimization in power generation connection, posture adaptation, and fulcrum stability. It belongs to 'human-controlled technology,' but has not yet reached the realm of 'human and skill as one.'"

"It may be good enough for others, but it's definitely not enough for him."

"so……"

"During the 2015 Bird's Nest World Championships cycle, Su completed a comprehensive and revolutionary upgrade of the flexor arm 3.0 based on the mature technology of flexor arm 2.0. From the support fulcrum to the closed loop of force transmission, from posture adaptation to neural control, every detail has achieved a qualitative breakthrough, completely breaking the bottleneck of flexor arm 2.0 and achieving zero internal friction in starting and exerting force."

"First, the angle of the bent-arm support is precisely locked, which is one of the core upgrades of the Bent-Arm 3.0. Unlike the range control of the Bent-Arm 2.0, the Bent-Arm 3.0 precisely calculates the optimal acute angle based on Su Shen's height, limb proportions, core strength characteristics, and force exertion habits. Through day-to-day specialized refinement, the angle error is controlled within 0.1 degrees. Every time in the squat preparation position, the arms are bent and flat on the ground, with the elbow joint angle perfectly locked at the optimal value. This precisely locked angle allows the shoulder girdle muscles to fully develop..." It forms a stable and absolutely rigid support point, with the support surface perfectly aligned with the core requirement of forward force generation. This fundamentally eliminates force transmission deviations caused by angle fluctuations, allowing the reaction force generated by the bent-arm support to be transmitted straight along the torso's central axis. This force is completely synchronized with the forward thrust generated by the coordinated push-off from the hips, knees, and ankles of the lower limbs. The combined force of these two forces is 100% used for forward propulsion, completely eliminating the hidden losses of vertical and lateral components, and truly maximizing the combined force – a breakthrough that the bent-arm 2.0 system has consistently failed to achieve.

"Secondly, the shoulder girdle and core muscles achieve a zero-delay rigid closed loop connection. This is the core upgrade of the 3.0 version in terms of neural regulation. Compared to the 'pseudo-synchronization' of the 2.0 version which relies on conscious control, the 3.0 version has undergone two years of specialized refinement, resulting in a qualitative leap in the efficiency of neural regulation of muscle groups. During the squatting preparation phase, the shoulder girdle muscles and core muscles have already entered a 'pre-tension' synchronous state. There is no need for sequential triggering. At the moment of the starting gun, the rigidity of the shoulder girdle support and the rigidity of the core support instantly merge into one, forming an impeccable rigid whole with no room for loosening. The force of the lower limbs pushing off the ground is transmitted from the soles of the feet to the hips, and then smoothly delivered to the torso and shoulder girdle. There are no breaks or loss of force throughout the entire process, maximizing the efficiency of force transmission. This allows every bit of explosive force from pushing off the ground to be converted into forward kinetic energy without any loss. This millisecond-level connection improvement may seem subtle, but it is the key to the acceleration of the 3.0 version and the core gap between it and the 2.0 version."

"Third, the bent-arm support and the extremely low center of gravity achieve a perfect mechanical fit. The bent-arm 3.0 further lowers the center of gravity, and the forward lean angle of the torso is closer to the optimal solution for force generation than the bent-arm 2.0 stage. More importantly, it achieves precise alignment of the three points of 'support point-center of gravity-force point', constructing the most scientific starting mechanical structure. This deep fit completely eliminates the shortcomings of the bent-arm 2.0, which relies on deliberate posture control. The head can naturally fit with the torso axis without active control, maintaining a stable posture and completely eliminating the instinctive reaction of raising the head at the moment of starting. It avoids the center of gravity shifting backward from the root, allowing the body to be in the optimal forward-leaning posture from the moment of start, and to rush forward with the inertia of the low center of gravity, further amplifying the effect of the combined force propulsion, making the forward kinetic energy of the start more sufficient and the inertia stronger."

"Fourth, the efficiency of neuromuscular recruitment has achieved an instinctive leap. The initiation of the 2.0 stage of bent arm movement still relies on the active control of technical awareness, which belongs to the transmission mode of "brain command - muscle group exertion". However, the 3.0 stage of bent arm movement completely integrates the technology into muscle memory and neural instinct. When squatting and preparing, the nerves have already activated the lower limb push-off muscles, upper limb support muscles, and core stabilizing muscles, and entered the ready state. At the moment the gun fires, the neural recruitment of the three major muscle groups is triggered simultaneously. Without the brain to deliberately issue commands, the muscle groups can accurately control the timing and force of exertion, achieve a high degree of coordination, and achieve the instinctive reaction of "exerting force when the gun fires and combining force when exerting force". This completely eliminates the delay loss of neural regulation and allows the smoothness and explosiveness of the initiation of force to reach the extreme."

In short, the 2013 Moscow cycle's L-2.0 was about "mature mastery and efficient power," relying on a stable technical framework to reach the world's top level and support the level of a "god of starters." The 2015 Bird's Nest cycle's L-3.0, on the other hand, was about "ultimate godhood and perfect harmony between man and skill." Building on L-2.0, it achieved a disruptive upgrade in four core dimensions: fulcrum locking, force chain closure, posture adaptation, and neural regulation. It maximized the biomechanical potential of the L-2.0 start, achieving zero internal friction, zero delay, and zero deviation in power generation. This was not a simple technical tweak, but a qualitative iteration. It gained a slight advantage from the very beginning compared to the L-2.0 stage. This slight advantage was the core foundation for Su's 60-meter run, taking him from "god of starters" to "true god of starters" and crushing the world's strongest rivals.

Even if that person is Bolt.

"The same level of lightning speed."

"That was an absolute crushing defeat."

"The second point I want to make is this key point: the center of gravity."

Green truly lives up to his title as the "Technology Emperor," the previous generation's technological king. He possesses a wealth of experience and theories. Now that he's in this field and working under Su Shen, he'll put even more effort into studying Su Shen's papers and various advanced theories.

This is to ensure that we can maintain our leading position in the industry.

As it turns out, his efforts were worthwhile.

It can keep pace with the times.

"The shift from '2.0 Stable Control and Adaptation' to '3.0 Ultimate Penetration' in center of gravity control is essentially about consolidating forward momentum by extending the golden zone of force exertion."

What does it mean to extend the golden zone of power generation and consolidate forward momentum?

Green said with a tone of half admiration and half boast: "Controlling the center of gravity is the lifeline of the early stages of the race. It directly determines the length of the acceleration distance and the efficiency of power generation. In the 2013 Moscow cycle, Su relied on the bent arm 2.0 technology and simultaneously implemented the center of gravity control system. It has already gotten rid of the drawbacks of the traditional starting center of gravity loss and premature uprighting. It has achieved low center of gravity stability and posture adaptation, laying a solid foundation for acceleration. It is at the top level of 'stable and well adapted,' but there are still bottlenecks in posture control that have not been overcome. In the 2015 Bird's Nest World Championship cycle, with the iteration of the bent arm 3.0, the center of gravity control has been fully upgraded. It has moved from 'stable control' to 'ultimate continuity,' allowing the low center of gravity posture to be deeply integrated with the power generation throughout the race. It has completely lengthened the acceleration zone and the mixed running zone, and consolidated the forward momentum throughout the race, becoming the core support for continuous acceleration without loss of power in the first 60 meters."

"The 2013 Moscow cycle's Center of Gravity Control 2.0 was already a mature system adapted to the Lever 2.0, clearly defining the core logic of 'lowering the center of gravity at the start and gradually raising the center of gravity during acceleration.' It completely abandoned the problems of an excessively high starting center of gravity and upward thrust during the push-off phase, and also solved the problem of disjointed power generation caused by a sudden rise in the center of gravity during acceleration. It could stably maintain a low center of gravity posture to complete the first 10 meters of start and the 10-30 meter acceleration, ensuring that the forward component of force always dominates and effectively reducing energy waste in the vertical direction. However, the Center of Gravity Control 2.0 at that time still had a slight shortcoming that limited the upper limit of the distance, and failed to achieve ultimate posture control."

"Firstly, the extreme low center of gravity is not enough. Although it can maintain a low center of gravity at the start, the forward lean angle is still retained, which is not the optimal angle that matches its own power characteristics. Compared with the later 3.0 version, there is still room for improvement in the height of the center of gravity, which results in the inertia of the forward lunge not being strong enough. In the initial stage of starting and acceleration, it is necessary to rely on some leg power to make up for the lack of inertia, and there is a slight redundancy in power exertion."

"Secondly, the smoothness of the center of gravity rise is lacking. During the 10-30 meter acceleration phase, although the center of gravity rises slowly, there are slight pauses in the rising rhythm. The adjustment of the torso's forward lean angle is not a gradual and smooth transition, but a small-amplitude step-like rise. This pause will cause a brief gap in the rhythm of the push-off and swing-off power generation, resulting in slight loss of kinetic energy transmission and making it easy for the core rigidity to fluctuate, making it impossible to maintain a stable power generation posture."

"Third, the adaptation of the center of gravity to the entire technique remains superficial. Center of gravity control is only basically adapted to the bent-arm start, without deep integration with hip drive and push-off coordination. This leads to occasional situations where the posture chases the center of gravity during the acceleration phase. For example, the center of gravity fails to keep up with the adaptation when the stride length increases, or the center of gravity sways slightly when the stride frequency increases, requiring deliberate posture adjustments to stabilize the center of gravity, further consuming physical and kinetic energy. Fourth, head stability relies on the passive adaptation of the center of gravity control posture. Although the head can be kept stable by a low center of gravity, the essence is that "a stable center of gravity leads to a stable head." Once the center of gravity fluctuates slightly, the head will instinctively adjust, failing to achieve active stability, which in turn affects the rigidity of the torso and causes hidden power loss."

"In short, the Moscow cycle's center of gravity control 2.0 is 'stable and well-adapted,' which can support world-class acceleration levels, but it still lacks in terms of perfection, smoothness, and integration. It belongs to 'posture adaptation technology' and has not reached 'posture integration into instinct.'"

"During the 2015 Bird's Nest World Championships cycle, the center of gravity control was upgraded in sync with the curved arm, achieving a qualitative change from 'stable control' to 'ultimate continuity,' comprehensively making up for the shortcomings of the 2.0 version, making the center of gravity the core link for exerting force throughout the entire process, and consolidating forward momentum."

"Firstly, the center of gravity is lowered to the extreme. Compared to version 2.0, the forward lean angle of the torso is further lowered to the optimal range that fits the body's own biomechanics. This completely eliminates unnecessary reserves, allowing the body to be in an 'extreme dive' posture from the moment of start-up. This extremely low center of gravity not only amplifies the combined propulsion effect of the bent arm 3.0, but also accumulates strong forward inertia, so that starting and acceleration do not rely on additional leg power. The body can rush forward with the inertia of the center of gravity, reducing redundant force from the source and allowing every bit of force to be focused on forward propulsion."

"Secondly, the center of gravity rise is smooth and gradual. The new version completely solves the problem of abrupt changes in the old stage. In the 10-30 meter acceleration and 30-60 meter mixed running stages, the center of gravity rises smoothly and without interruption. The torso lean angle adjusts linearly and gradually from the extremely low center of gravity to the center of gravity that is suitable for the middle run, without any step-like fluctuations. This smooth rise keeps the core rigidity stable throughout the entire process, the rhythm of the push-off and swing is seamless, the kinetic energy transfer is lossless throughout the entire process, and the distance of the acceleration zone is greatly extended, avoiding the premature termination of acceleration due to abrupt changes in the center of gravity rise, laying a solid foundation for sustained top speed in the 30-50 meter range."

"Thirdly, the center of gravity is deeply integrated with the entire process technology. Center of gravity control 3.0 is no longer just a single posture control, but forms a closed loop with hip drive, push-off and swing coordination, and stride frequency and stride adjustment, building a linkage system of "center of gravity leading power and power matching center of gravity". During the acceleration phase, when the stride length expands, the center of gravity sinks and adjusts in sync to ensure that the forward force of the push-off does not decrease; when the stride frequency increases, the center of gravity remains stable and does not sway, supporting the high-frequency arm swing and push-off; after 30 meters, when entering the mixed running phase, the rhythm of the gradual rise of the center of gravity is precisely matched with the highest speed entry point, so that the speed increase and the center of gravity adjustment are perfectly synchronized, completely eliminating the problem of "posture chasing center of gravity" and achieving seamless matching between power and posture."

"Fourth, head stability becomes instinctive. The center of gravity control 3.0 constructs an absolutely stable structure with the support point, center of gravity point, and head point in a straight line. It is no longer the passive adaptation of the 2.0 version where the center of gravity is stable and the head is stable. Instead, the head forms an instinctive stability with the center of gravity and torso. There is no need to deliberately control the posture. Even when accelerating at high speed or the center of gravity is slowly raised, the head always stays in line with the axis of the torso and the line of sight is straight forward. This completely eliminates the center of gravity shift caused by head shaking or raising the head, further consolidates the core rigidity, and reduces hidden energy loss."

"In other words, the Moscow cycle center of gravity control 2.0 is 'stable and adaptable,' supporting efficient acceleration throughout the entire process; while the Bird's Nest cycle center of gravity control is 'extremely compressed, smoothly lifted, and thoroughly integrated,' making the center of gravity the core link for the entire process, extending the golden zone of force exertion, accumulating strong forward inertia, and providing the most solid posture support for continuous acceleration in the first 60 meters and precise entry into the highest speed in the 50 meters."

"Then I think there is another point of change for the future, which is the third point that he can strive for excellence and take it a step further. The power chain transmission has changed from "continuous transmission in the previous version" to "zero-disruption closed loop in the new version", maximizing the power efficiency and achieving lossless transmission of kinetic energy.

"The core competitiveness of sprinting lies in the efficiency of the kinetic chain transmission. The power transmission from the feet to the hips, from the hips to the core, and from the core to the upper limbs, the connection of each link determines the upper limit of power. In the 2013 Moscow cycle, Su combined the flexed arm 2.0 with the center of gravity to build a kinetic chain transmission system, achieving a leap from 'zero power dissipation' to 'continuous transmission', and the power efficiency ranked among the world's top. However, there were still transmission breaks and hidden losses. In the 2015 Bird's Nest new cycle, with the dual support of the flexed arm 3.0 and the center of gravity adjustment, his kinetic chain transmission was also upgraded to a new version, achieving a closed-loop transmission with zero breaks throughout the entire race, maximizing power efficiency, and ensuring lossless kinetic energy transmission. This became the ultimate guarantee for the layered speed in the first 60 meters and the locking of the top speed without decay."

"If the kinetic chain transmission 2.0 of the 2013 Moscow cycle had already broken through the shortcomings of the traditional sprint's fragmented power generation and disconnected power transmission, and constructed a coherent transmission path of 'lower limb push-off - core transmission - upper limb support,' clarifying the key role of the core as the central hub of the kinetic chain, and completely changing the earlier power generation logic of 'emphasizing the lower limbs, neglecting the core, and ignoring the upper limbs,' allowing the explosive power of the lower limb push-off to be smoothly transmitted through the core, and then combined with the reaction force of the bent arm support to form a combined force, achieving coherent and efficient power generation, then the kinetic chain 2.0 at that time still had a transmission shortcoming that was difficult to see with the naked eye but affected the ultimate efficiency."

"Firstly, there are millisecond-level breakpoints in the kinetic chain connection. Although the lower limb hip, knee and ankle extension force, core rigidity transmission, and upper limb shoulder girdle support can be connected, they are not triggered synchronously. Instead, they present a progressive pattern of 'lower limbs exert force first - core transmits then - upper limbs follow up.' This millisecond-level difference in timing prevents the kinetic chain from forming a seamless closed loop. There are slight losses in the power transmission process, making it impossible to achieve 100% transmission of explosive power."

"Secondly, the core transmission rigidity is insufficient. Although version 2.0 emphasizes the role of the core, the core rigidity can only maintain basic stability. During high-speed acceleration, especially after 30 meters when entering the mixed sprint stage, the inertial impact brought by the increase in body speed will cause the core to undergo extremely slight deformation. This deformation causes the power transmission path to deviate, and some of the explosive power is converted into internal friction within the core, which cannot be fully transmitted to the whole body."

"Thirdly, there is a lack of coordination between the upper and lower limbs. Although the lower limbs push off and the upper limbs swing in rhythm, they do not form a precise coordination of force. For example, when the lower limbs push off the ground, the force and amplitude of the upper limbs swing are not precisely matched, resulting in a slight collision between the upper and lower limbs, which further consumes kinetic energy and fails to achieve the optimal effect of 'the upper and lower limbs exerting force in the same direction and superimposing the combined force'."

"Fourthly, the kinetic energy transfer between the push-off and swing is incomplete. During the landing and cushioning phase, there is a brief gap between the lower limb muscle group's cushioning and the push-off. The elastic potential energy is not fully stored during cushioning and not fully released during push-off, resulting in the inability to transfer 100% of the kinetic energy from each step to the next, causing a slight loss of kinetic energy and affecting the continuous accumulation of speed. In short, the Moscow cycle's kinetic chain transmission 2.0 is 'coherent and efficient, with sufficient force,' capable of supporting world-class speeds. However, there is still room for improvement in the closed-loop transmission, core rigidity, and coordinated force exertion. It belongs to 'coherent force exertion' but has not achieved 'lossless transmission.'"

Green took a sip of water and casually inserted an advertisement for the sponsor.

Then he continued.

"During the 2015 Bird's Nest cycle, the power chain transmission 3.0 achieved a revolutionary upgrade based on the 2.0. Relying on the zero-delay support of the articulated boom 3.0 and the full-process stability control of the center of gravity 3.0, it built a zero-discontinuity closed loop of 'full-process rigidity, synchronous triggering, coordinated force exertion, and lossless transmission', pushing the force exertion efficiency to the extreme."

"Specific changes have been made to address the above issues one by one."

"Firstly, the kinetic chain achieves zero-delay synchronous triggering, which is the core breakthrough of version 3.0. It completely changes the progressive force exertion mode of version 2.0. Through the ultimate refinement of neural regulation, it achieves synchronous triggering and synchronous force exertion of the three elements: lower limb push-off, core conduction, and upper limb support. When the gun fires and the lower limbs push off in coordination with the hip, knee, and ankle, the core immediately locks in rigidity, and the upper limbs exert force synchronously with the bent arm support. There is no difference in sequence or delay between the three. The kinetic chain forms a closed loop from the moment of start, and the force transmission is uninterrupted throughout the entire process. The explosive force of the lower limbs pushing off the ground is instantly integrated with the reaction force of the upper limb support through the core rigidity center, achieving nearly 100% transmission of explosive force with almost no loss."

"Secondly, the core conduction achieves absolute rigidity throughout the entire process. The kinetic chain 3.0 strengthens the training of deep core muscle groups, making the core rigidity far superior to the 2.0 version. Not only can it lock in stability during the start and acceleration phases, but even when entering the high-speed mixed running phase after 30 meters, the core can maintain impeccable rigidity without any slight deformation, even when facing the inertial impact of increasing speed. This absolute rigidity makes the core a 'seamless center' for power conduction. Power is transmitted from the lower limbs to the core and then distributed to the whole body, with a straight path without deviation, completely eliminating energy consumption within the core, and allowing every burst of power to be accurately transmitted."

"Thirdly, the upper and lower limbs achieve ultimate coordination. Version 3.0 breaks away from the shallow coordination of 'rhythm coordination' in version 2.0 and achieves precise matching and coordination of 'force intensity, amplitude, and timing'. When the lower limbs push off the ground, the force of the push-off is perfectly matched with the force of the upper limbs swinging their arms, the amplitude of the push-off corresponds precisely with the amplitude of the arm swing, and the timing of the push-off is perfectly synchronized with the timing of the arm swing, forming 'upper and lower limbs exerting force in the same direction.' This not only avoids force collision but also creates a superposition of combined forces, further amplifying the forward propulsion force and doubling the efficiency of kinetic energy superposition."

"Fourth, the transition between the push-off and swing achieves lossless kinetic energy transfer. Version 3.0 optimizes the landing cushioning and push-off techniques, allowing the lower limb muscles to fully store elastic potential energy during the cushioning phase. The push-off force is triggered immediately after the cushioning ends, with zero gap between cushioning and push-off, achieving a seamless connection of 'landing as cushioning, cushioning as push-off.' The kinetic energy of each step can be stored through elastic potential energy and then fully released through push-off, 100% transferred to the next step, completely eliminating kinetic energy loss and allowing speed to accumulate layer by layer, continuously increasing without decay from the start to 60 meters."

"In short, the Moscow Cyclic Power Chain Transmission 2.0 is 'continuous force exertion and efficient transmission,' supporting the world's top-level performance; while the Bird's Nest Cyclic Power Chain Transmission 3.0 is 'zero-discontinuity closed-loop and lossless transmission,' relying on the support of the 3.0 articulated arm and the 3.0 center of gravity to achieve synchronous force exertion, core rigidity, ultimate synergy, and seamless push-off and swing, maximizing the biomechanical efficiency of power chain transmission, so that every step exerted in the first 60 meters can form a combined force superposition. This is the ultimate technical core that enabled the Soviet Union to reach the human ceiling and crush the world's strongest rivals in the first 60 meters."

"With this one move, I think it will be almost impossible for anyone to come close to Bolt for the next half century."

"One of them is a god of future prospects."

"One is a true god in the later stages."

"God created man in such a dramatic way that he would always arrange for you to have an opponent, and they all mastered their own hearts and fought to the extreme."

"Of course, there are definitely many blind spots in my knowledge that I haven't covered or can't address. But that's not something I can explain in a general sense; I can only say..."

"Su's match."

"The more you analyze, the stronger it becomes."

"The more I analyze it, the more terrifying it becomes."

"Okay, let's first thank our sponsors for this event, Sprite, for a refreshing summer treat."

"My heart is soaring."
