The Su God of the Reopening of the Sports Arena

Chapter 2433 Xie Zhengye 21! The true peak is about to descend.
Besides Chen Juan.

The moment Wei Yongli crossed the finish line, she also achieved a good result.

Not far away, Wei Yongli staggered a couple of steps after crossing the finish line and had to grab the railing next to her to steady herself.

She stared at the number "22.79" on the timer, stunned for two seconds.

He then let out a long sigh of relief.

He raised his hand to wipe the sweat from his face.

A relieved smile tugged at the corner of his mouth.

Breaking through 22.80!

Despite being located on a high plateau with wind speeds exceeding one meter.

But as long as we can break this record.

This means that the body can handle it.

Wei Yongli was already very happy.

Third is Liang Xiaojing.

After crossing the finish line at the age of eighteen, she immediately squatted down on the ground.

He was panting heavily, his hands supporting his knees, his chest heaving violently.

When she saw the number "23.15" on the timer, she clenched her fist tightly.

Third, they just barely qualified for the World Championships.

It also exceeded the qualifying time of 23.20 seconds.

She slowly stood up, supporting herself on her knees, and waved towards the stands, where her family members were holding signs that read "Xiaojing, keep going!" and jumping and shouting her name.

Fourth is Kong Lingwei's time of 23.18 seconds.

Fifth is Ge Manqi's time of 23.20 seconds.

The sixth score was Lin Huijun's score of 23.25.

Yuan Qiqi, 7th, 23.28.

Wang Xuan and Cheng Chong's time was 23.80 seconds.

Five people passed the qualification line directly this time.

It's a pity there weren't enough spots to participate in the competition.

However, this also shows that even at 200 meters...

The athletes from Ersha Island also began to gradually dominate.

The status of traditional departments is being squeezed smaller and smaller.

This competition is a snapshot of the strength of domestic women's 200-meter athletes. The strongest, for example, Chen Juan, already has a time of 22.15 seconds; she just needs to maintain that level.

In major competitions, he can achieve a time of around 22.20 seconds.

It is already competitive for a medal.

That's enough.

The main reason is that the number of people who met the standard reached five at once.

This is also the first time in history.

This describes these young girls.

They have finally grown up.

女子200米结束之后轮到男子200米上场。110米栏和女子200米都有好成绩出现的情况下，大家自然也更加期待男子200米。

The current men's 200-meter record is 19.65 seconds, set by Suarez.

Xie Zhengye's best score is 19.70.

However, Suarez will not be participating in the 200 meters this time.

Because all his efforts are focused on the 100 meters, he is going to do something big in the 100 meters this time, so he can't afford to be distracted.

Did you hear that, Su Shen?

Xie Zhengye was feeling a bit bored.

However, Su Shen quickly found him some motivation.

"Look how fast Gatling has suddenly become this year. If you don't take him down, your third place in the world might be in jeopardy."

"Young man, if you can't win a medal at the Bird's Nest, you might regret it for the rest of your life."

These words really stung Xie Zhengye.

"19.68, that's his best time last year. You need to at least break that record."

"If you can't get 19.70 seconds, I think you're in big trouble this time."

"Of course, you can prove me wrong and show me what you're doing."

After saying this with a smile, Su Shen turned and left.

He knew the desired effect had been achieved.

Xie Zhengye was now filled with primal rage.

Of course, another reason he provoked Xie Zhenye was...

Gatlin will achieve even more terrifying results by the end of June this year.

It will surge directly to 19.50+.

He didn't want to thank Zhengye, because the gap would be too big by then.

He planted his own mental demons during the competition.

19.60+, at least 19.57 seconds away, not that far off, it's not like there's no chance of a fight.

However, 19.70+ feels like it's several levels below 19.50+.

Therefore, Su Shen hopes.

Xie Zhengye can put his efforts to good use here.

It is the best venue in the country for achieving good results.

In front of the Bird's Nest.

Refresh your personal Pb.

……

"Alright, viewers, the exciting women's 200m race has ended, and the men's 200m final is about to begin."

"The athletes who have qualified for the men's 200-meter final are Xie Zhengye, Zhou Bing, Liang Jiahong, Liang Jinsheng, Tang Xingqiang, and Pan Xingyue..."

"We can see that there are many new faces this time."

"This shows that my country's sprinting has entered a new era."

"However, this competition shouldn't be too suspenseful, but as long as you can meet the requirements, you'll have a chance to participate."

"Although Su Shen didn't participate in this competition, if no one else can meet the requirements, then this wildcard will probably be given to him."

"But if someone can reach the standard of 20.50 seconds, the award will still be given to the person who participated in the competition and met the standard."

"This was something that the head coach of the track and field team, Yu Weili, had already mentioned before the competition."

“This is a very fair thing to do.” Li Tao agreed with this.

"Otherwise, the significance of the athlete running this race would be greatly diminished."

"In this respect, Su Shen and his team did a very good job, leaving no room for controversy."

"Of course, if you can't meet the requirements, then there's nothing we can do but give the spot to him."

"This is also why Su Shen ran a 200-meter race to meet the standard this year. Otherwise, he probably wouldn't even bother to run the 200 meters. His main goal this year was the 100 meters."

"Alright, the match is about to begin."

"Let's see how the men's 200 meters turn out."

Who are the top 4?

"This time, we have a wildcard entry for the 200 meters. If we run well, we also have a chance to run in the World Championships in Beijing."

"The prerequisite is that you can achieve the standard of 20.50 seconds."

……

"Get in your positions."

Qingtangcheng Sports Center.

The command traveled across the arena, and all eight athletes simultaneously bent down, their differences in technique becoming immediately apparent the moment they braced themselves with their hands on the ground.

Xie Zhengye and Zhou Bing simultaneously assumed the starting stance with their arms bent.

However, it reveals the characteristics of the school in the details.

Xie Zhengye's "step frequency type" bent arm is more compact: the elbow is bent to 110°, the hands are clenched into fists, only the knuckles touch the ground, the back of the hand is at a 30° angle to the track, the distance between the knuckles is 1 cm narrower than the shoulder width, the shoulders are slightly lowered, and the whole upper body is like a compressed short spring - this design aims to shorten the explosive power transmission path, while reserving space for high-frequency arm swing after the start.

His front knee was only 3 centimeters off the ground, his back foot was completely pressed against the starting block, his ankle was taut like a fully drawn bowstring, his core muscles were deliberately tightened, his body weight was shifted forward to 5 centimeters in front of his shoulder line, and his breathing was slowed to 12 breaths per minute to avoid chest expansion affecting the stability of his power.

Zhou Bing, in the fourth lane next to Xie Zhengye, displayed the "stride-type" bent-arm characteristic: the elbows were bent at a slightly larger angle, the knuckles touched the ground more when the hands were clenched into fists, the distance between them was 2 centimeters wider than the shoulder width, and the center of gravity was 1 centimeter further back than Xie Zhengye.

The front knee is 5 centimeters off the ground, and the power point of the rear leg pushing off the ground is biased towards the outside of the foot, clearly building up power for a large stride after the start—

The stride-type articulated arm does not pursue the ultimate starting speed, but rather achieves it through a slightly wider support surface and a slightly larger elbow angle.

Balance explosive power with stride length expansion space.

Liang Jiahong, on the other hand, adopted the "standard rigid straight arm support".

With arms fully extended and elbows locked, a stable support baseline is formed, shoulder-width apart.

The palm fully conforms to the lychee-textured surface of the track, with fingertips pointing forward and aligned with the track texture, maximizing contact area to enhance friction.

Keep your wrists in a neutral position and your forearms at a 90° angle to the ground. By using the "long lever arm principle", the weight of your torso is evenly distributed to your palms. During the support phase, you can withstand about 80% of the pressure from the forward lean angle of your body. This effectively prevents the support point from shifting when you push off the ground at the start, which is suitable for your explosive power and strong push-off force.

Liang Jinsheng chose the "wide-range buffer straight arm posture".

The distance between the hands is 15cm wider than the shoulder width, forming an "outward-expanding support structure". The fingers are spread about 0.5cm apart, allowing the raised texture of the lychee-patterned running track to be embedded in the gaps between the fingers, increasing the contact points by an additional 20%.

The forearm is tilted slightly outward by 5° to widen the support surface and reduce the center of gravity projection area, thus addressing the problem of delayed muscle activation in the low-oxygen environment of high altitude.

It also benefits from the lateral stability provided by the wide spacing of the support.

To counteract the lateral torque that may be generated when the body leans forward at the beginning of the race.

It is adapted to the characteristics of its technical style, which is "stable start-up rhythm and gradual exertion".

Tang Xingqiang in lane seven used the "wrist elastic cushioning straight arm technique".

When supporting yourself on your arms, bend your elbows slightly, not completely locking them to allow for a small range of motion.

The moment the palm touches the ground, the wrist actively flexes inward by 3°, forming an "elastic support angle" that makes the wrist joint a buffer fulcrum.

When the reaction force generated by the foot pushing off the ground is transmitted to the arm, the wrist can absorb 15%-20% of the ground impact through slight deformation, avoiding excessive stretching of the wrist tendons caused by rigid support.

The distance between your hands should be shoulder-width apart.

However, the fingertips are slightly offset inward by 10°.

Enhance the traction guidance for trunk extension.

It is adapted to its technical requirements of "fast step frequency and rapid acceleration after startup".

Pan Xingyue, in the first lane, adopted a "semi-rigid straight arm micro-adjustment posture".

With arms extended but elbows retaining 10° of range of motion, a "flexible support structure" is formed.

When the palm is on the ground, the inner side of the palm is slightly raised, with only the heel of the palm and the fingertips as the main support points, reducing the contact area between the middle of the palm and the track, and reducing the stickiness of the palm caused by the friction of the lychee texture at the moment of starting.

The wrists are in a relaxed, natural state, without being deliberately locked or strained. The natural curvature of the wrists helps to cushion the impact force from the ground, while the distance between the hands is slightly narrower than the shoulders.

The compact support structure enhances the upper limbs' control precision over the torso, adapting to the technical characteristics of "lightweight body type, requiring precise support to control body balance".

You can actually see that this group of young players all have some scientific elements in their approach.

This is because Su Shen and his team have repeatedly won honors on the international stage.

They even took it to 100 meters, a height they never dared to imagine before.

With results already at this level, the rest of us have no choice but to study.

In addition, there are retired athletes who studied on Ersha Island and then went to work at the grassroots level in various places.

These ways of thinking were gradually spread.

These scientific models were gradually promoted and disseminated.

These are all typical changes.

It's clear that even if they weren't studying on Ersha Island...

They also gradually began to accept these scientific concepts.

This serves as an endorsement of victory.

The strength of the promotion.

In addition, the higher authorities are willing to do so. After all, with continuous breakthroughs and achievements, who wouldn't want to give them a boost?

So during this period of time.

The Su Shen system spread rapidly across the country.

It is already quite evident that some young athletes are beginning to see changes in their training fundamentals and philosophies.

Zhou Bing adopted a "wide-angle bent-arm support" starting posture: both arms are bent at 90°, the elbow joint angle error is controlled within ±3°, and the distance between the hands is 20cm wider than the shoulder width, forming an "outward-expanding bent-arm structure".

The palm is partially pressed against the surface of the lychee-patterned track, with only the base of the palm and the outer side of the fingertips exerting force. The contact area is about 80cm, and the fingertips are tilted outward at 15° to form a cross-interlocking with the track texture.

The angle of the rear starting block footplate is adjusted to 65°.

The hind leg is bent at the knee joint to 140°.

Heels off the ground 4cm.

Two 5mm long spikes on the outer forefoot of the spikes are embedded 3mm into the elastic layer of the track.

Three 4mm short nails are embedded 2mm inside.

The torso leans forward at an angle of 40°.

The center of gravity projection point is biased towards the outer side of the support surface.

It forms a "long torque line" with the point where the rear foot pushes off.

The 20cm wide-spaced curved arm supports expand the support area to 150cm.

With a 25% increase in spacing compared to the standard, combined with the high friction coefficient of 0.85 on the lychee-patterned track, the static grip can reach 127.5N, providing 30% more support than the narrower spacing.

This design is precisely suited to his physiological characteristics of "85kg weight and peak push-off force of 2200N". The wide support surface can effectively disperse the reaction force when pushing off the ground and avoid stride inaccuracy caused by center of gravity shift.

Meanwhile, the "rigid buffer structure" formed by the 90° elbow flexion can absorb 15% of the ground impact through the small deformation of the elbow joint, so that the control error of the upper limb on the trunk is controlled within ±0.5cm, laying a stable foundation for subsequent large stride extension.

The "gradient embedding" design of the outer long spikes and inner short spikes, with the help of the differentiated rebound characteristics of the lychee pattern track elastic layer, shifts the force of pushing off the ground by 5° to the outside, which works in synergy with the external rotation force of the hip joint.

The 65° footplate angle increases the knee angle of the rear leg to 140°, activating the coordinated contraction of the quadriceps and gluteus maximus, extending the time for pushing off the ground to 0.12 seconds, which is 20% longer than the traditional 75° footplate, allowing for full storage of elastic potential energy.

This design perfectly matches the technical requirement of "exchanging the depth of the push-off for the length of the stride", so that the first stride at the start is more than 1.5 meters, which is more than 0.3 meters longer than that of stride frequency type athletes.

To accelerate the stride to 2.2 meters+, a smooth transition curve was constructed.

The "long moment line" formed by the projection point of the center of gravity and the point of push-off can efficiently transmit the force of the legs pushing off the ground to the torso through the support lever of the wide curved arm, with a force transmission efficiency of 92%, which is 10% higher than that of the straight arm support.

The cross-bite design between the palm and the track utilizes the raised structure of the irregular texture of the lychee pattern to add 18 contact points, increasing lateral anti-slip force by 40% and preventing the foot from slipping during large strides.

Meanwhile, the swing amplitude of the wide-arm can reach 130°, forming a synergistic effect with the forward swing of the legs, achieving a "push-swing synchronization rate" of 95%.

Reduce redundant actions and costs.

This stabilizes the step size growth rate at 8%/second during the acceleration phase.

This is Zhou Bing's current wide-width curved arm-pedaling swing coordinated stride-type technical system.

It is mainly for stride length.

Xie Zhengye's situation was slightly different.

The starting posture adopts the "compact curved arm support".

With both arms bent at the elbows to 100°, the elbow joints can be dynamically adjusted within a 5° range. The distance between the hands is the same as the shoulder width, forming an "inward-curving arm structure".

The palm fits fully against the lychee-patterned running track surface, with fingers spread 0.3cm apart, allowing the raised texture of the track to fit into the gaps, providing a contact area of ​​110cm. The fingertips should face directly forward, aligning with the direction of the texture.

The angle of the rear starting block footplate is adjusted to 60°.

The hind leg is bent at the knee joint to 130°.

Heels off the ground 2cm.

Eight 4.5mm triangular anchor-shaped spikes are evenly embedded 2.5mm into the elastic layer of the track in the forefoot of the spikes.

The torso leans forward at a 45° angle, with the center of gravity projected close to the front edge of the supporting body, forming a "short torque line" with the forefoot.

The 100° dynamic elbow flexion architecture eliminates the redundant "push-bend" motion of straight arm support, reducing neural response delay to 0.1 seconds, a 25% improvement over traditional straight arm support.

This design precisely suits its physiological advantage of "reaction time of only 0.13 seconds". After the brain receives the starting signal, the arm can bend and swing directly into the swing phase, reducing the action connection time.

The full palm fit and finger gap interlocking design, combined with the high friction coefficient of the lychee-patterned running track, enables a grip of 93.5N, generating an effective reaction force at the moment of push-off in 0.02 seconds, providing immediate support for high-frequency strides.

Eight evenly distributed triangular anchor-shaped spikes form a "multi-point uniform engagement" with the track's elastic layer. The force exerted by each spike on the ground is controlled within ±5N, avoiding excessive local force that could disrupt the rhythm of the push-off.

The 60° footplate angle reduces the knee angle of the rear leg to 130°, activating the rapid contraction ability of the hamstring muscles and shortening the time for pushing off the ground to 0.08 seconds, which is 33% less than Zhou Bing's power exertion time, enabling a high-frequency cycle of "rapid push-off - rapid lift-off".

This design is a perfect fit for its "cadence priority" technical requirements.

At startup, the center of gravity projection point forms a "short moment force line".

This reduces the upper limb's response time to the trunk to 0.01 seconds, allowing for real-time correction of push-off deviations and controlling stride frequency fluctuations within ±0.1 steps/second. The arm swing amplitude is compressed to 110°, with a swing frequency of 5.0 times/second, achieving a "1:1 synchronous match" with the leg push-off frequency, avoiding rhythm lag caused by wide swings.

The low-viscosity texture design of the lychee-patterned surface of the track, combined with the compact curved arm support, can reduce arm swing resistance by 20%.

It reduces energy consumption in the upper limbs by 15%.

To maintain energy reserves for high-frequency strides in the second half of the race.

In addition, dynamic support activates muscle reflexes.

The 100° adjustable elbow joint provides "elastic support".

The brief imbalance that Xie Zhengye experiences when pushing off the ground will trigger a reflexive contraction of his leg muscles.

This increases the frequency of pushing off the ground by 10%.

This "imbalance-compensation" mechanism is precisely suited to its technical characteristics of "relying on rapid neuromuscular activation to achieve high-frequency step frequency". Combined with the instant rebound characteristics of the lychee-patterned track, it can make the energy feedback efficiency of each step up to 75%.

It is 25% better than stride-type athletes.

Ensure continuous energy supply at high-frequency step rates.

"preparation--"

As the starter's voice faded, the stadium fell into the calm before the storm.

Xie Zhengye made a slight adjustment to his bent-arm support, reducing the elbow bend angle to 105°, increasing the pressure of his knuckles on the track, and causing his shoulders to sink 2 centimeters more. The compression of his upper body was visible to the naked eye, and his fast-twitch muscle fibers entered an activated state ahead of time in a low-oxygen environment.

Zhou Bing adjusted his exertion rhythm by slightly trembling his calf muscles, maintaining the stability of his bent arm support without any reduction, and slightly raising his hips, creating a contrast with Xie Zhengye's "one pressing down and one lifting up" movement.

Liang Jiahong's straight arm support remained motionless, his gaze fixed on the ground marker 5 meters ahead, using visual focus to shield himself from interference.

Jingsheng's fingers curled slightly, activating the nerves in his hand to enhance his support sensitivity.

Bang————————

"Game start!"

The moment the gun fired, the advantages of the double-curved arm technique were simultaneously unleashed, yet they exhibited different power generation logics.

Xie Zhengye's elbow straightened rapidly in 0.01 seconds, and as his knuckles left the ground, his hind leg pushed off the starting block, and the explosive power of his quadriceps was transmitted directly to his whole body through the "short lever arm".

The force transmission path of the step-frequency type curved arm is 1/3 shorter than that of the straight arm, and the start-up delay is reduced by 0.005 seconds.

Although his first step was short, he immediately entered a high-frequency alternation after landing, with his step frequency instantly exceeding 4.0 steps per second.

The torso leans forward at an angle of 36°.

Like a black lightning bolt, it was the first to break the deadlock.

Zhou Bing's approach to the project leans towards "steady progress."

The explosive power from the bent-arm support allowed him and Xie Zhengye to leave the ground almost simultaneously, but the stride length technique enabled his first step to reach 2.0 meters, which was 0.2 meters wider than Xie Zhengye's.

However, the slightly wider elbow angle caused a 0.002-second delay in power transmission, resulting in him landing half a foot behind Xie Zhengye on the first step.

The pace is slightly slower.

It is clearly trading step size for speed.

The straight-arm athlete's start was noticeably delayed.

Although Liang Jiahong's straight-arm support is stable, the power needs to be transmitted through three levels: "palm-forearm-upper arm". It takes 0.01 seconds after the start to fully accelerate, and he is already one foot behind the double-bend arm athlete when the first step lands.

Liang Jinsheng's wide-grip straight arm movement caused his core power to be dispersed, resulting in fluctuations in his step frequency.

Tang Xingqiang and Pan Xingyue's straight-arm movements were standard but lacked explosiveness, instantly putting them at a disadvantage compared to the top group.

Five meters after the start, the technical differences become even more pronounced. Xie Zhengye's stride-frequency bent-arm swing advantage becomes apparent. His arms are naturally bent at 90°, with his fists close to his waist when swinging forward and his elbows not exceeding the midline of his torso when swinging backward. His arm swing frequency is stable at 4.3 steps per second, and each swing precisely propels his body forward, with the torso's forward tilt angle remaining consistently stable.

Zhou Bing, taking advantage of his stride length, increased his second stride to 2.1 meters. Although his stride frequency was slightly slower, he made up for the difference by increasing his stride length, keeping the distance between him and Xie Zhengye at half a body length.

Liang Jiahong's straight arm swing is still being adjusted, taking 0.01 seconds.

He was 0.5 body lengths behind Zhou Bing, while the other contestants were several body lengths or more behind.

They did a good job of cutting into corners.

Entering the acceleration phase.

As they entered the acceleration phase of the curves, the track's curvature began to emerge, and Xie Zhengye and Zhou Bing's advantage in lever arm control shifted from "starting burst" to a duel of "acceleration logic."

Xie Zhengye's step-frequency type of bent-arm acceleration is even more "compact and efficient". His arm swing frequency has been further increased to 4.5 steps/second, and the swing amplitude of the bent arm is always controlled within 30 centimeters.

The left arm swings slightly less than the right arm.

This is the "curving adaptation strategy" for cadence-based bent-arm movement. It reduces air resistance by swinging the arm slightly asymmetrically, while simultaneously tilting the body inward by 3° to improve cadence stability by leveraging the centripetal force of the curve.

His push-off technique leans towards "rapid alternation." When pushing off with his left foot, the ball of his foot slightly turns inward, while his right foot pushes off with a forward force. Each step's contact time with the ground is shortened to 0.06 seconds, almost "bounces up as soon as the foot lands." In the low-oxygen environment of the plateau, this rapid push-off can reduce the sluggishness of force exertion caused by muscle hypoxia.

Xie Zhengye's step-frequency type curved arm skillfully employs "dynamic fine-tuning" during acceleration in corners.

Instead of simply increasing his stride frequency, he adjusted the "power point" of his arm swing in real time according to the changes in the track's curvature.

When the track just begins to curve at the 10-meter mark, his left arm swings back slightly later than his right arm swings forward slightly earlier than his left arm swings forward. By using this tiny time difference, he tilts his body inward in advance to avoid rhythm disruption caused by sudden tilting later on.

At 15 meters, the arc increases to its maximum. He then shifts the "power center" of his bent-arm swing downward, changing from shoulder-dominant to elbow-dominant. Although the bending angle of his arms remains stable at 90°, the muscle contraction amplitude when exerting force at the elbow decreases. This maintains a high-frequency arm swing of 4.3 steps per second while reducing the fatigue consumption of the shoulder muscles under low oxygen conditions.

In the push-off phase, he took "step frequency to beautify the curve" to the extreme.

When pushing off with the left foot, the ball of the foot should touch the ground 1 cm inward from the toes. By using the "inner pull" generated by the ground reaction force, and coordinating with the high frequency of steps, you can quickly enter the curve trajectory.

When pushing off with the right foot, the toes point outwards, using "external support" to balance the risk of imbalance caused by the body tilting. The deviation of the left and right feet touching the ground is controlled within 0.5 centimeters, and each step is like "gliding on the curve".

At 20 meters, he encountered the first "small hurdle of hypoxia" in the high-altitude acceleration, and his fast muscle fibers experienced a brief delay in exertion. Instead of forcibly increasing his strength, he stabilized his stride frequency at 4.2 steps per second by reducing the range of his arm swing from 30 centimeters to 28 centimeters.

By employing a strategy of "reducing the rate of increase while maintaining frequency," we can smoothly navigate the bottleneck period in our efforts.

Thus.

The speed didn't drop at all.

Instead, it increased by 0.1 m/s compared to 15 meters.

Zhou Bing's stride-type curved arm takes the hard approach of "expanding the stride with stability".

He knew that the stride length was most vulnerable to sudden reduction due to the curvature when accelerating on a curve, so he used the "wide traction" of the bent arm swing to stabilize the stride length starting from 10 meters.

The range of arm swing gradually increases from 35 cm at the start to 38 cm. When swinging the arms left and right, the elbows are deliberately extended backward by 2 cm more than when swinging forward. With the help of the traction of the backward swing, the range of motion of the hip joint forward is increased by 1.5 cm.

Make sure the first step is 2.0 meters long, the second step is 2.1 meters long, the third step is 2.2 meters long, and so on.

The step size increases at a uniform rate without any fluctuation.

To support the ever-expanding stride length, his curved arm support logic was also adjusted.

When accelerating through a curve, although the hands remain in a fist with the knuckles touching the ground, the distance between the knuckles is reduced from 2 centimeters wider than the shoulders to 1 centimeter wider than the shoulders. By using the slightly narrower support surface, the core's control over the body is improved, and the body twisting is avoided when pushing off the ground with a large stride.

At 18 meters, his right leg's fast-twitch muscle fibers experienced slight soreness due to lack of oxygen. If he continued to extend his stride, it could lead to imbalance, so he immediately made a slight adjustment to the point of force exertion when pushing off the ground.

Shift the weight of your right foot from the outside to the middle.

At the same time, the force of the backswing was reduced, and the stride length was stabilized at 2.2 meters. Instead of forcibly pursuing a breakthrough in stride length, a strategy of "stable amplitude and speed" was adopted.

Maintain the speed at 3.8 m/s.

The speed difference between him and Xie Zhengye was always kept within 0.2 meters per second.

The core logic behind Xie Zhengye's step-frequency type articulated arm is "dynamic adaptation"—

Instead of pursuing perfection in any particular aspect, the goal is to create a "self-regulating closed loop" in the body's movements.

Therefore, starting from the 10-meter mark, his core muscles are no longer a rigid "support frame," but rather like a flexible "hydraulic system," adjusting the force exertion in real time according to changes in the track's curvature.

As the curve begins to take shape, the core muscles on the left side subtly tighten, while the right side relaxes appropriately. By utilizing this difference in muscle strength between the left and right sides, the body naturally tilts inward, using centripetal force to increase speed while avoiding any jerking caused by deliberate tilting.

This adjustment is not a mechanical "angle setting," but an "instinctive reaction" driven by muscle memory, just like the body automatically balancing when riding a bicycle. It requires no deliberate calculation, yet it is surprisingly precise.

More importantly, he understands the importance of controlling the pace to "gain more with less." For cadence-based athletes, blindly pursuing high frequencies is a major pitfall, and Xie Zhengye is well aware of this.

When he senses that his muscle endurance is about to reach its limit, he will not force himself to maintain peak cadence. Instead, he will make subtle adjustments to his torso posture—slightly narrowing his shoulder width and lowering his upper body center of gravity—to reduce the impact of air resistance on his body. He will use these small changes in posture to offset the speed loss caused by the slight decrease in cadence.

This strategy of "sacrificing the part to save the whole" allows his acceleration process to be like a smooth curve, without drastic fluctuations, but it can expand his advantages through continuous accumulation.

Zhou Bing's stride-type bent-arm technique follows the route of "rigid posture to maintain stride extension." He understands that the core of a large stride is "the coordinated power generation of the torso and lower limbs," therefore, starting from 10 meters, he uses a "core rigidity lock-in" strategy:
The rectus abdominis and latissimus dorsi muscles maintain 90% tension simultaneously, creating a "rigid support" for the torso and preventing the upper body from leaning forward or backward when pushing off the ground with large strides.

At the 14-meter mark, his stride length increased to over 2.2 meters. To ensure that the power from his lower limbs was fully transferred to his torso, he fine-tuned the angle of his hip joint.

Increase the forward movement of the hip joint by 2 centimeters, while simultaneously using "forward and backward traction" through the bending and swinging of the arm.

This causes the shoulder and hip joints to move forward in unison.

Ensure the propulsive force of each step.

All of these can be efficiently converted into forward distance through a rigid torso.

Instead of wasting time on body swaying.

His energy allocation strategy also revolves around "stable stride," emphasizing "gradual progress and conserving energy for the later stages."

In the initial stage of acceleration on a curve, he will not rush to extend his stride to its maximum, but will gradually increase the stride length at a uniform rate, giving his muscles time to adapt to the low-oxygen environment.

Once his stride length reaches the ideal range, he stabilizes his power output within a reasonable range, not pursuing instantaneous bursts of speed, but maintaining speed through continuous and stable output.

This "steady and reliable" style allows him to waste almost no energy during acceleration, and even in low-oxygen environments, he can conserve enough stamina for the rest of the race.

These are two different people.

But there are also similarities.

For example, when faced with changes in the curvature of a curve, Xie Zhengye and Zhou Bing's approach is as follows:

"Actively adapt" rather than "passively adapt".

They would fine-tune the angle at which their feet landed based on the curvature of the track, so that their feet would fit the curve like "tracks," ensuring grip while avoiding a reduction in stride due to track deviation.

This "sense" of the track allows him to maintain a long stride and high frequency without being limited in the curves.

Instead, it can utilize the centripetal force of the arc.

Make each step forward more advantageous than when on a straight road.

Compared to them.

The challenges faced by straight-armed athletes are much greater.

However, difficulties have arisen.

It is precisely because of the lack of diversity in technology.

Liang Jiahong's straight-arm acceleration still relies on the traditional logic of "arm swing for added force, and pushing off the ground for power," lacking precise control over the core posture.

When the curves become more pronounced, his lack of core control causes his body to tilt at varying angles, resulting in frequent fluctuations in stride frequency and stride length, and intermittent speed increases.

Liang Jinsheng fell into the trap of "energy waste." In order to catch up with the bent-arm athletes, he blindly increased the swing amplitude, but the force transmission efficiency of the straight-arm swing was low.

Most of the energy is wasted on ineffective movements; the faster you accelerate, the more strenuous it becomes.

The issues concerning Tang Xingqiang and Pan Xingyue are more basic.

They lacked Xie Zhengye's skillful "dynamic adaptation".

It also lacks Zhou Bing's "rigid and stable" tenacity.

It's just a machine repeating the action of accelerating on a straight road.

There are no strategies to deal with variables such as the curvature of curves and high-altitude hypoxia.

When the track environment changes, their technical system is like an instrument that has lost its calibration.

Accuracy has dropped significantly.

The gap between them and the top tier is naturally widening.

Running on a curve.

Xie Zhengye.

A sudden burst of power!

suddenly.

The speed increased.

They outnumbered Zhou Bing by a large margin.

This is because of... Xie Zhengye's breakthrough in the 100 meters.

The core challenge was overcoming the problem of "core rigidity and rhythm stability in short-distance high-speed running".

The "core dynamic locking" technique he honed during 100-meter training allows the core muscle groups to maintain a force output accuracy of 0.1 seconds during high-frequency output.

This ability, when applied to running on a 200-meter curve, directly solved his previous problem of "instability due to continuous acceleration on curves".

At 35 meters, while other athletes began to experience core tremors due to continuous tilting and exertion, Xie Zhengye's core muscle group acted like a precise "hydraulic control system," with his rectus abdominis and erector spinae muscles maintaining stable tension, even though his left arm swing was 1/5 smaller than his right arm due to the demands of the curve.

There was no twisting of the upper body, the torso leaned forward at a stable angle of 35°, and the coordination error between the high-frequency arm swing and the push-off action of the step-frequency bent arm was controlled within a range that was difficult to detect with the naked eye.

More importantly, the "high-speed running rhythm perception" brought about by the 100-meter breakthrough allows him to accurately capture the body's "endurance threshold" in low-oxygen environments.

40 meters.

His fast-twitch muscle fibers began to transmit fatigue signals.

In previous 200-meter races, this often required adjusting by slowing down. Now, he uses the muscle memory he developed during 100-meter training to actively activate "rhythm micro-adjustment": he shifts the center of gravity of his arm swing from his shoulder to his elbow, shortening the lever arm to reduce energy consumption in his shoulder muscles while maintaining a stable stride frequency.

In other words, the force of pushing off the ground is only slightly adjusted by 10%.

Xie Zhengye thus avoided the bottleneck of endurance.

There was no loss of speed.

This ability to "dynamically fine-tune at high speeds" is the core advantage that his 100-meter breakthrough gives him.

Ordinary athletes can only "passively adapt" to fatigue.

And he can "actively regulate".

Minimize the impact of fatigue on rhythm.

In addition, the "muscle exertion timing optimization" technique, which was mastered during the 100-meter training, became the key to Xie Zhengye's breakthrough in overcoming endurance bottlenecks during curve running.

The extreme requirements for "precision of the force exertion point" in the 100-meter sprint led him to develop a set of "muscle group relay force exertion" logic.

Instead of the previous 200-meter sprint model of "simplely mobilizing all muscle groups to output high intensity synchronously", it allows different muscle groups to form a closed loop of force exertion in the order of "core-lower limbs-upper limbs".

By staggering the exertion of muscles, the oxygen consumption pressure caused by simultaneous muscle work can be reduced.

45 m.

During the mid-race phase of the curve, when other runners' core and lower limb muscles begin to show signs of fatigue due to synchronized exertion, Xie Zhengye has already activated this timing optimization strategy.

The rectus abdominis first stabilizes the trunk at 60% intensity, then the quadriceps follow up with a push-off 0.02 seconds later, and finally the shoulder muscles drive the arm swing during running.

This slight delay in exertion allows each muscle group a brief "recovery interval," preventing the rapid buildup of lactic acid caused by continuous tension.

Especially at the 45-meter mark, when Zhou Bing's lower limb muscles trembled slightly due to synchronized exertion, Xie Zhengye's quadriceps were still able to maintain a stable pushing force, thanks to the muscle cushioning provided by this "staggered relay".

More importantly, the ability to "elasticity stripping" developed during 100-meter training allows him to completely eliminate ineffective movement during curves.

In the past, his bent-arm swing would have a slight lateral swing, which did not affect his stride frequency, but would consume an extra 10% of his upper body strength.

After refining the "simplification of movements" over 100 meters, his arm swing trajectory has been completely narrowed to "parallel front and back", the lateral deviation when the elbow swings is controlled to a minimum, and each arm swing is precisely pointed in the direction of forward movement without any unnecessary movements.

This elimination of "ineffective force" allows his upper limb muscles to maintain high-frequency arm swings while reducing physical exertion by 15% compared to the past, indirectly saving endurance reserves for his core and lower limb muscles.

50 m.

Xie Zhengye's "muscle group temporal optimization" has been further upgraded.

The core muscle stability strength is reduced from 60% to 55%, and the energy saved is transferred to the lower limbs to push off the ground. At the same time, the center of gravity of the upper limb arm swing is lowered from the shoulder to the elbow, reducing the burden on the shoulder by using a shorter lever arm.

This ability to "dynamically allocate physical strength" is an extension of the "instantaneous force control" technique used in 100-meter sprint training.

When ordinary athletes lack endurance, they often slow down across the board. However, Xie Zhengye can achieve "localized load reduction and focused speed maintenance" by adjusting the intensity of force exerted by different muscle groups, ensuring that his stride frequency and push-off efficiency do not decline significantly, but instead continue to improve.

Extreme speed zone.

Xie Zhengye's step-frequency curved arm entered the "peak output" state. His arm swing frequency increased again to 4.5 steps/second.

The range of motion of the bent arm swing is increased to 30 centimeters. When swinging forward, the fist is close to the chest, and when swinging backward, the elbow extends backward to the limit. The inertia of the arm swing is used to improve the continuity of the stride frequency.

His core muscles were taut like steel cables, and the contraction of his external oblique muscles increased by 10% compared to when he was running, ensuring that his body did not twist at high stride frequency, and that his torso leaned forward at a stable angle of 35° without leaning backward due to increased speed.

65 meters.

Bang bang bang bang bang.

Xie Zhengye's instantaneous speed reached its peak throughout the race. Although the specific data can only be analyzed after the race is over, judging from the changes in the gap between him and Zhou Bing, his stride frequency advantage made his speed increase more obvious, and the gap between the two continued to break through the body length barrier.

It's difficult to describe the difference between them even from their positions.

It needs to be measured in meters...

One meter, two meters, three meters.

Xie Zhengye is here.

He showcased his hard work and training over the past two years.

It also demonstrated the change in intensity of the 100-meter dash after his physical fitness improved.

His push-off technique entered "rapid rebound" mode.

The time it takes for the foot to strike the ground is reduced to 0.05 seconds, which is 0.01 seconds less than during the middle run.

This "lightning push-off" reduces muscle fatigue in low-oxygen environments, while using the centripetal force of curves to ensure that the propulsion of each step is precisely directed in the forward direction.

This shows that he can also handle cornering skills.

Just this one shot.

Su Shen believes.

Xie Zhengye these past two years.

It wasn't in vain.

The final result of this shot.

It is worth looking forward to.
