The Su God of the Reopening of the Sports Arena

Chapter 2548 Technology from the Future! No matter how perfect you are, you'll still be crushed!

This……

Liu Xiang was excited.

The others were dumbfounded.

Mills, who had just been full of confidence, felt as if he had been struck by lightning.

They clearly pulled ahead of the American team in one fell swoop.

They have already firmly secured the number one position.

And so, in that brief moment of distraction during the handover...

On the Chinese team's side.

A red figure.

It had already jumped from third to almost neck and neck.

How is this possible? It's absolutely outrageous.

Carter believed he had performed exceptionally well with that shot and the handoff was also excellent.

There shouldn't be this problem at all.

After all, if the handover was really not done well, how could the US team have pulled away by so much?
That's strange.

That's impossible.

Mills knew very well that he had just achieved the feeling he had been looking for.

If that's the case, how could it be possible?
Not only did they seize all the advantages, but even the handover that he thought he had done very well...

They were all counterattacked and killed by the opponent.

They swallowed up the gap in one go.

That's really too big.

of course.

Nobody knows why.

Only core team members knew this.

Yu Weili and Yuan Guoqiang watched, initially breaking out in a cold sweat, since this was the first time this technique had been used in a major competition.

During the preliminary rounds.

I've never used it to hide my shortcomings.

That's right.

This set is the technical modification made by Su Shen.

Specifically designed for relay races.

每个人都知道，现代接力接力赛跑是田径运动的重要组成部分，分为4×100米、4×200米、4×400米等多个项目。

The essence of the competition is the organic combination of "individual speed" and "teamwork".

It's completely different from individual competitions.

An individual can influence the team's performance, but cannot turn the tide alone.

Moreover, in modern high-level competitions, the speed gap between individual athletes is gradually narrowing, and baton passing techniques have become a key variable in determining the outcome of the game.

When Su Shen was carrying out this technical modification, he provided a complete report.

His report shows that in modern relay races, the baton exchange segment accounts for 15%-20% of the total time of elite athletes in the 4×100m relay.

A successful baton exchange can save 0.3-0.5 seconds.

There could be even more.

A single mistake could lead to defeat in the game.

For a long time, even after Suarez came to the sport, the track and field world generally adopted the "standing baton," "downward pressing," and "upward lifting" baton passing techniques. The "standing baton" technique will not be introduced here, as it is no longer used by many teams and is gradually being phased out in professional teams. The "downward pressing" technique involves the passer pressing the baton down to complete the handover, while the "upward lifting" technique involves the passer lifting the baton upward to complete the pass.

In practice, these two traditional models have also begun to reveal many problems:

For example, if the baton exchangers are not moving at the same pace, it can lead to a significant loss of speed.

For example, the limited contact area with the hand increases the risk of dropping the rod.

For example, their movements are too large and they are easily affected by the competition environment and opponents.

and many more.

With the improvement of the scientific level of modern track and field training, athletes' overall speed is constantly breaking through, and the bottleneck of traditional baton passing techniques is becoming increasingly prominent. There is an urgent need for a more efficient and stable technical model to meet the needs of competition.

So, besides this one, is there a third new way?

Of course there are.

Now Su Shen has brought it.

This is a concept that will only gradually become more widespread after 2020. It's estimated that it will be another 10 years or so before it's truly used comprehensively.

However, he was the one who restarted it.

It comes with advanced technology in this area.

Although the "downward" and "upward" baton passing techniques have historically driven the development of relay racing, their limitations are becoming increasingly prominent in the modern competitive environment.

Even with all the improvements Su Shen made, some fundamental issues still couldn't be corrected.

For example, there is a significant loss of speed.

In both of these traditional modes, the receiving runner usually accelerates only when the passing runner is close, resulting in a speed difference between the two at the moment of handover. The passing runner needs to slow down to coordinate, while the receiving runner needs to accelerate quickly.

This results in a significant loss of speed.

Data from the Sushen Lab shows that the speed loss rate of traditional methods is generally between 10% and 15%.

In the 4x100m relay, every loss of speed can affect the final ranking.

Secondly, the handover stability is insufficient: the "downward-pressing" baton has a small contact area with the hand, making it easy for the baton to slip from the fingertips.

When passing the baton in an "upward flick" motion, the receiving athlete's hand is less stable when catching the baton, and the risk of dropping the baton is higher when running at high speed and swaying the body.

According to statistics, the bat drop error rate in traditional international competitions is about 3%-5%. If an upward adjustment is adopted, the probability may even rise to more than 10%. In a crucial game, a single bat drop can lead to a complete loss.

Secondly, redundant actions affect efficiency.

In both traditional modes, the baton-passing player needs to complete the separate actions of "passing the baton" and "releasing the hand", while the baton-receiving player needs to complete the continuous actions of "receiving" and "gripping".

There are obvious gaps in the transitions between actions throughout the process.

The handover time is generally between 0.5 and 0.8 seconds.

It is difficult to meet the "seamless connection" requirement of modern relay races.

Finally, they have poor adaptability.

The traditional model places certain requirements on the physical conditions of the baton exchangers, such as height and arm length.

Moreover, it is suitable for complex racing environments such as headwinds and curves.

Movement stability is easily affected, and technical performance fluctuates greatly.

What are the differences in the core principles and key technologies of the "forward-pushing" baton passing technology?

First and foremost, is it about the core principles?

The "forward-pushing" baton passing technique uses "dynamic synchronous advancement" as its core logic, breaking the inherent logic of "the baton passer actively passes the baton and the receiver passively receives it" in the traditional model.

A "two-way active, same-speed connection" transmission system has been constructed.

Its core principles can be summarized in the following three points:
1. Speed ​​Synchronization Principle: The receiving runner accelerates and adjusts their rhythm in advance based on the running speed and route of the passing runner, ensuring that the speed difference between the two runners is controlled within 0.1m/s at the moment of baton exchange, achieving "parallel running at the same speed". This speed synchronization eliminates the losses caused by speed differences in the traditional mode, integrating the baton exchange process into the overall running rhythm, rather than a separate "pause-exchange-start" phase.

2. The principle of bidirectional force transmission: While running at the same speed, the runner passing the baton actively delivers it to the receiver by pushing forward with their arm. The receiver, in turn, actively receives the baton by extending their arm forward, creating a counterforce. This bidirectional force transmission makes the baton transfer smoother and faster. This active bidirectional movement pattern increases the contact area between the hands and improves the stability of the handover.

3. Integrated Movement Principle: The "forward-pushing" baton exchange integrates the "passing" and "receiving" actions into one. The "forward push" of the passer and the "receiving" of the receiver are completed simultaneously, with no obvious gap in movement. Throughout the exchange, the arm movements of both players are smooth and continuous, reducing redundant movements and significantly shortening the exchange time.

4. Spatial Pre-aiming and Trajectory Optimization Principle: The baton exchangers must pre-plan the spatial coordinates of the handover area using visual pre-aiming and proprioception. This includes lateral spacing and longitudinal position, and dynamically optimizes the baton transfer trajectory. The baton exchanger controls the forward extension angle of their arm around their shoulder, ensuring the baton is passed along the "shortest straight path." The receiving baton exchanger, through slight torso rotation and directional arm extension, forms a "receiving channel" precisely aligned with the transfer trajectory, avoiding contact deviations caused by trajectory offsets and further shortening the handover time. This principle solves the problems of unstable transfer trajectories and reliance on on-the-spot reactions in traditional models, improving handover accuracy through pre-set trajectories.

5. Neuromuscular Synergistic Activation Principle: The "push-forward" baton exchange demands extremely high levels of synchronized neuromuscular activation. At the moment of the push, the passer's core and rotator cuff muscles contract synergistically, forming a stable power base, and the arm flexor and extensor muscles rapidly complete the "pre-pull-push" elastic deformation transition. The receiver, in the pre-start phase, activates the hand flexor and forearm muscles, maintaining a "pre-tension state." When the baton touches the palm, nerve signals are rapidly transmitted to the muscles, achieving an instantaneous "contact-grip" response. This neuromuscular synergistic activation avoids the problems of delayed grip and disjointed power generation caused by delayed muscle activation in traditional methods, improving the smoothness of the movement transition.

6. The Principle of Energy Conservation and Efficiency Maximization: In traditional baton passing, the deceleration of the passer and the acceleration of the receiver result in kinetic energy loss, with some energy being converted into heat or wasted due to adjustments in movement. However, the "forward-pushing" method, by running at the same speed and in sync, keeps the kinetic energy of both runners relatively stable. The baton exchange only needs to overcome air resistance and hand friction, minimizing energy loss. Simultaneously, the passer's forward push utilizes running inertia, and the receiver's receiving motion is converted into forward momentum, forming a closed loop of "kinetic energy transfer-conversion-utilization," maximizing energy efficiency. This principle aligns with the core objective of modern track and field: "to achieve maximum speed with minimal energy loss."

7. Environmental Adaptability and Anti-interference Principle: The "forward-pushing" baton passing technique enhances adaptability to complex competition environments through standardized movements and fixed rhythms. In scenarios such as headwinds, curves, and crowd interference, the baton exchangers rely on the core rhythm of "synchronization at the same speed" to reduce adjustments caused by environmental changes. The larger contact area of ​​the hands and the bidirectional force ensure the baton remains stable even in swaying environments, reducing the impact of external interference on the handover. In contrast, the traditional method, with its larger movement range and concentrated contact points, is more sensitive to environmental changes and has weaker anti-interference capabilities. This principle gives the "forward-pushing" technique greater stability and reliability in actual competition.

8. Arm Posture Rigidity Control Principle: During the baton exchange, both players' arms must maintain a controllable rigid posture—the passing player's elbow is slightly bent but not locked, preserving power buffer, and the forearm pushes forward parallel to the ground to prevent arm swaying that could cause the baton to deviate; the receiving player's arm is straight, the wrist joint is fixed, and the palm faces the direction of the baton exchange to form a "rigid receiving surface," not changing angle with body swaying. This principle eliminates the baton drop/exchange delay caused by loose arms and uncontrolled posture in the traditional model, ensuring a stable baton transmission path.

9. Precise Positioning Principle in the Relay Zone: The receiving runner strictly adheres to a preset stride frequency, using the first third of the relay zone as the core handover point. They accelerate in advance with a fixed number of steps (e.g., 6-8 steps in sprint relays to reach the same speed). The passing runner simultaneously adjusts their stride length to ensure the exchange is completed within the optimal area of ​​the relay zone, without crossing the zone or arriving too early or too late. This solves the problem of arbitrary handover positions in traditional models, leading to violations of the zone or speed mismatches, and adapts to the competition rules and the need for maximum speed.

10. Principle of Movement Replication and Muscle Memory Consolidation: The "pre-start rhythm, forward push force, and receiving timing" of the forward-pushing baton pass need to form standardized muscle memory. During training, this is achieved by repeatedly fixing the movement paradigm. For example, the baton passing force should be based on "delivering the baton precisely without letting it slip from the hand," and the receiving timing should be based on "grasping the baton as soon as it touches the palm." This allows athletes to complete the movement instinctively without conscious adjustment while running at high speed. Unlike the flexibility of traditional methods, this principle ensures consistency of technical movements in high-pressure competitions, avoiding on-the-spot errors.

These are the 10 key points of the new technology personally listed by Su Shen.

This is why fundamental changes are necessary.

Because of this new adhesive bonding technology, compared to the pressure bonding method, it has the following advantages—

Minimal speed loss.

The downward-pressing baton transfer requires the baton transferor to slow down and the receiving baton transferor to raise their hand to receive it, with a speed difference of 0.3-0.5 m/s.

The forward-pushing parallel speed has a speed difference of ≤0.1m/s, and the single handover loss is reduced by 0.2-0.3 seconds. The cumulative difference of 4×100 meters can widen the level difference.

The handover will be more stable.

The downward-pressing design only allows for contact with a small area of ​​the fingertips/palm, making it prone to slipping.

The forward-pushing bidirectional active bonding has a contact area that is 2-3 times larger, and the rod drop rate is more than 50% lower than that of the downward-pressing type.

The movements are smoother.

The press-down mechanism has a redundant "press-release" action, requiring 0.5-0.8 seconds for handover.

The forward push motion is integrated, with a handover time of only 0.3-0.5 seconds, and requires no significant adjustment of arm posture, thus not disrupting the running rhythm.

Strong anti-interference ability.

The downward-pressing arm has a large downward range, and it is easily affected by body swaying when facing headwinds or curves.

The forward-extending arm posture is stable and has a low probability of motion deformation in complex scenarios.

Compared to the advantages of the upward-sloping style.

It also features smoother speed transitions.

The person receiving the baton in the upward-reaching style needs to bend over/bend their arm to coordinate, resulting in a delayed start and acceleration, and a speed loss rate of 12%-18%.

The forward-pushing baton receiver extends their straight arm forward, maintaining the same speed throughout the race, with only 3%-5% energy loss, making it suitable for the extreme speed requirements of sprinting.

The grip is highly secure.

The upward-pointing type relies on the tiger's mouth for support, and the rod body can easily slip out of the tiger's mouth.

The forward-pushing design fully wraps the palm, allowing for an instant grip after receiving the baton, resulting in an error rate of only 1%-2%, making it more reliable in high-pressure events.

It has wider compatibility.

The upward-sweeping style is sensitive to the height difference between players; a difference of more than 10cm can easily lead to mistakes. The forward-pushing style can be adapted to different height combinations by adjusting the lateral spacing, and has fewer restrictions on team pairings.

Secondly, it requires less effort to exert force.

The person passing the bat upwards needs to exert force upwards, which consumes additional shoulder and arm strength.

The forward-pushing running momentum propels you forward without requiring extra effort, saving energy that can be used to run faster in the front, without holding back any energy.

Therefore, the core advantage of the forward-pushing universal approach is that it completely surpasses the two traditional models.

The first, of course, is efficient energy utilization.

Traditional methods waste kinetic energy during the "deceleration-acceleration" cycle. The forward-pushing, constant-speed operation, however, suffers almost no energy loss and can even convert the transmission motion into forward propulsion.

The second technology is highly replicable.

Once mastered, it easily forms muscle memory, resulting in greater stability of movements in high-pressure competitions compared to the traditional model that relies on on-the-spot coordination.

Of course, it's not fair to say that there are no disadvantages; as a new technology, it certainly has its drawbacks.

Su Shen also made this point very clearly in his report.

The disadvantages of the forward-pushing baton passing system, and the shortcomings that objectively exist in actual combat, are fourfold.

The basic entry barrier is high.

The basic ability requirements for athletes are higher than those for the downward press/uplift style. Athletes with no experience may easily distort the movements if they learn it directly, while the traditional method can be mastered in 1-2 training sessions.

Physical exertion increased slightly.

The runner needs to start accelerating precisely in advance, which consumes 5%-8% more starting energy than the traditional mode, and multiple relays can easily lead to fatigue in the later stages.

The rule adaptation requirements are strict.

The handover area requires extremely high positioning accuracy. If the step frequency deviates, it is easy to commit the "early handover" or "handover outside the designated area" violation. The traditional handover mode has a higher tolerance for error.

Not suitable for long-distance relays.

The forward-pushing core is suitable for 4×100/200m sprints. In long-distance relays such as 4×400m, athletes' speed fluctuates greatly and it is difficult to maintain the same speed for a long time, so their advantages cannot be brought into play. The traditional mode is more suitable.

Therefore, Su Shen wrote it very clearly here.

Because he was afraid these people wouldn't understand.

Especially those upper-level personnel who do not have a technical background.

If we don't explain it to them clearly, they'll be completely lost, like they're reading gibberish.

The core difficulty of the forward-looking approach, mastering the key bottlenecks, and the biggest learning gap compared to the traditional model, is...

The core technical challenges.

After all, this is still a new technology, so there will definitely be technical barriers.

If you can't overcome the technical hurdle, it means you'll never master this new technology.

It is indeed not easy to do. Just look at a few examples and you'll find that it is very difficult.

Just like matching at the same speed, the accuracy is difficult to control.

The speed difference at the moment of handover must be ≤0.2m/s.

The receiver must accurately predict the speed and pace of the person passing the baton and start in advance. Being a little too fast or too slow will lead to a handover error. The traditional model does not require strict synchronization of speeds and has a high tolerance for error.

The timing and force of the pass are difficult to synchronize.

The person passing the baton must push forward at a constant speed at the moment of parallel movement. If the force is too light, the baton will not be delivered; if the force is too heavy, it will easily slip out of the hand. The person receiving the baton must "grasp it tightly as soon as it touches the palm of their hand." The two must coordinate with zero delay.

Regarding this point, Su Shen was frank and said directly that it is probably more than twice as difficult as the downward pressing "press and catch" or the upward lifting "lift and grasp".

Not to mention the difficulty in maintaining a rigid arm posture.

After all, this is happening at high speed.

It's not being transmitted while the object is stationary.

The baton passer should keep their elbow bent and steady, while the receiver should keep their arm straight and wrist fixed. Throughout the process, they must resist the swaying of their body while running. Beginners are prone to their arms becoming weak, causing the baton to deviate. In the traditional mode, the arm posture is flexible and there is no need to deliberately control rigidity.

Another example is the difficulty in accurately positioning oneself in the handover area.

In principle, the pace should be accelerated to the same speed in a fixed number of steps, and the handover should be completed in the first third of the relay zone.

If this is the case, a one-step difference in pace will result in crossing the zone/delaying the handover. In the traditional mode, the handover can be completed at any position in the relay zone without needing to be at a specific point.

And it's not easy to connect them intentionally.

All of this only addresses the technical difficulties.

Don't forget, relay races are a team event.

Then there are still difficulties at the coordination level.

It's like... the process of developing rapport between two people takes a long time.

The passing and receiving teams need to repeatedly practice "pre-start signal, peripheral vision coordination, and rhythm response," requiring at least several dozen weeks of specialized training to reach the required level, while the traditional model allows players to play after only 3-5 rehearsals.

When multiple people are relaying a race, it is even more difficult for everyone to maintain a unified rhythm.

Secondly, there is the difficulty in adapting to individual differences.

Players in a team have different heights, strides, and acceleration abilities, so it is necessary to make targeted adjustments to the start time and lateral spacing. For example, if a tall player passes the bat and a short player receives it, more practice is needed to adapt the spacing. In contrast, the traditional mode does not require additional adjustments.

Even if you don't care about these two issues, there's still a training hurdle you need to overcome.

This might even be the biggest pain point in your implementation.

Learning directly without any prior knowledge is likely to lead you astray.

Beginners often confuse "pushing forward" with "passing the baton," turning it into "the person passing the baton actively passes it on, and the person receiving the baton passively receives it."

It is actually slower than the traditional model. You need to practice speed perception first and then practice passing and receiving. You can't skip any steps.

Secondly, it is prone to deformation under high pressure.

While training may meet the standards, during competitions, headwinds, opponent interference, and the pressure to win can easily cause panic, leading to premature or late starts and arm wobbling. In contrast, the traditional method involves simpler movements and is easier to perform under pressure.

These difficulties are really giving me a headache.

Because most people don't even understand the underlying principles, let alone overcome these difficulties.

Especially since the competition is coming up right after Moscow, right on their home turf at the Bird's Nest.

How many people are counting on this match?
What's the point of inventing and creating things at this time?

Is it useful? Is it helpful to us?
It won't help you either.

If you want to do this kind of creative research, can't you wait until you retire or finish this competition?

Of course, this is just a pretext. After this competition, there's the Olympics.

Moreover, this is what Su Shen considers the best time, as there have been no major competitions for a full two years.

In addition, the ivory-like improvements made earlier were all for the purpose of this transformation.

If we don't act now, when will we?

Therefore, Su Shen deliberately wrote two copies. After the first copy was submitted, it sparked discussion. Not long after, he immediately submitted the second copy, which was the solution, at the same time.

Don't blame him for this; he's just short on time and has an urgent mission. He has too many things to do, and he's been busy competing against Bolt all these years.

It can be said that from 2011 until the Moscow tournament in 2013, there was a major competition every year.

I'm absolutely exhausted.

This is also a crucial moment in the fight against Bolt.

He couldn't concentrate.

Fortunately, London, Moscow, and Daegu all seized the opportunity.

Then he has the qualifications and the means to make such demands.

Of course, the solution should also be submitted as a condition.

To put it simply, the methods for winning over Su Shen can be summarized in these few points:

Overcome technical difficulties.

Su Shen adopted a step-by-step approach to break down training and precisely overcome key obstacles.

1. Matching at the same speed: First practice "following and running at the same speed". The baton bearer runs at a constant speed, and the receiver accelerates from behind to catch up, maintaining parallel running for 3 seconds. Then mark the starting point and fix the signal "baton bearer to the marked point - receiver starts", practice until the speed difference is stable at ≤0.1m/s.

2. Timing + Force: Use "light resistance push training" where the person passing the baton practices pushing with a baton that has light resistance, fixing the force of "palm force, uniform speed of passing the baton"; the person receiving the baton practices the "grasp upon touch" reaction. A bystander randomly passes the baton, practicing gripping it within 0.1 seconds. When the two are coordinating, they call out commands, such as "pass-receive," to solidify the rhythm.

3. Arm rigidity: Practice "straight arm forward extension static hold" against a wall to strengthen arm strength. Practice "empty-handed forward push-catch" while running to correct arm swaying, then practice with a stick to gradually solidify the posture.

4. Handover zone positioning: Draw a "starting point - handover point" line on the track, fix the receiving person to accelerate to the handover point, practice the step rhythm repeatedly, and use a stopwatch to time to ensure that each handover is in the optimal range.

Overcoming the challenges of teamwork: from two people to a team, honing tacit understanding step by step.

Teamwork: First practice "non-verbal coordination," using peripheral vision to observe your teammate's shoulder and back movements to judge when to start. Then practice passing and receiving in simulated headwind/curve scenarios. Practice 3 times a week, 20 sets each time. Basic teamwork can be formed in about 10 weeks.

Individual differences adaptation: Adjust the lateral spacing according to the height difference of the players. The spacing is 0.3m within 5cm of the difference and 0.4m for a difference of 5-10cm. Adjust the starting time according to acceleration ability. The baton receiver who accelerates slowly starts 0.2 seconds earlier. Customize exclusive cooperation plan.

Of course, this is just the simplest method and steps. Su Shentong wrote out all the detailed methods and procedures.

I really wish I could feed them bite by bite.

More importantly, they have no choice but to do it now. They have already pushed the downward modifications to their limit and there is no way to make any further progress.

Then it's time for a qualitative change.

Or rather, it wasn't until this point that you understood why Su Shen had been gradually improving the downward-pressing handover process.

Almost every year, the relay team undergoes minor adjustments.

The reason is that he plans to seamlessly integrate the latest technology system after Moscow.

Why is it a downward pressing style, and not an upward lifting style, or a standing stick style?

To understand why the modified downward-pressing type is easily converted into the forward-pressing type, we must first distinguish the core differences between the traditional downward-pressing type and the modified downward-pressing type.

The latter is not a simple minor adjustment to the former, but rather a targeted optimization by Su Shen focusing on "reducing speed loss and improving handover stability".

Its optimization direction is perfectly aligned with the core technology of the forward-pushing approach.

It could even be said that this laid the groundwork for the subsequent transformation very early on.

For example, the core weakness of traditional down-press systems.

The runner passing the baton needs to actively press down on the baton, and the runner receiving the baton needs to raise their arm with their palm facing up to receive it. During the handover, the runner passing the baton needs to slow down slightly to coordinate, and the runner receiving the baton needs to raise their hand to adjust their posture. This results in a speed difference of 0.3-0.5 m/s and a handover time of 0.5-0.8 seconds.

Furthermore, hand contact is concentrated only at the front of the palm and fingertips, resulting in a small contact area and a drop rate of 3%-5%.

At the same time, the downward pressing motion is large and can easily disrupt the running rhythm, and the probability of motion distortion is high in scenarios such as headwinds and curves.

The core optimization direction of the improved downward-pressing type is completely in line with the technical requirements of the forward-pushing type.

The first force application method has been optimized, abandoning the "large downward pressing" and replacing it with "forward delivery of the rod + slight downward pressure". The main direction of force application has changed from "vertical downward" to "horizontal forward", retaining only the slight downward pressure action to prevent the rod from slipping. In essence, it is close to the force application logic of the forward-pushing "active forward delivery".

The second speed coordination optimization requires the baton passer to maintain constant speed throughout the entire process, while the receiving baton passer starts accelerating 2-3 meters in advance, achieving "near-synchronous speed" at the moment of handover, with a speed difference of ≤0.2m/s. This breaks the inherent pattern of the traditional downward-pressing "deceleration coordination" and aligns with the core principle of the forward-pushing "synchronous parallel speed".

The third optimization of the baton contact emphasizes that the receiving athlete's palm covers a large area of ​​the baton, rather than the traditional fingertip receiving. The contact area is increased by more than 2 times, and the stability of the grip is greatly enhanced, which is consistent with the stability logic of the forward-pushing type of "two-way fit and complete palm receiving".

The fourth aspect of the movement has been optimized, simplifying arm movements. The baton-passing athlete should slightly bend their elbow and extend their forearm forward to pass the baton, while the receiving athlete should extend their arm forward without raising their shoulder. This avoids large movements interfering with the running rhythm, and the continuity of the movements is closer to the "integrated movement" requirement of the forward push.

The fifth aspect is the optimization of body stability. It abandons the unbalanced body posture of the traditional down-pressing baton receiver, which is characterized by "raising shoulders and hands and leaning forward." It requires both the baton receiver and the receiver to maintain an upright running posture throughout the entire process, with relaxed shoulders and neck and a stable torso. After the handover, no additional body posture adjustment is required to connect the sprint. This is in line with the technical requirements of the forward-pushing baton receiver, which is "continuous and seamless body posture."

The sixth handover zone positioning optimization breaks away from the vague logic of the traditional downward-pressing "arbitrary handover within the relay zone". It clearly defines the first 1/3 of the relay zone as the core handover point. The receiving runner completes the starting acceleration and positioning in a fixed step, eliminating the violation of crossing the zone or the hasty handover at the end, which is in line with the practical standard of "precise positioning and rule adaptation" of the forward-pushing style.

The seventh point is individual adaptability optimization, which addresses the shortcoming of the traditional downward pressing method being "sensitive to height differences." By fine-tuning the lateral distance between the two parties in the transmission, the distance is 0.3m within a height difference of 5cm, and 0.4m for a height difference of 5-10cm. This adapts to different height combinations without changing the core movement range, and is compatible with the forward-pushing method's "flexible team matching, no individual condition restrictions" adaptation logic.

Every optimization directly addresses the core issues of the traditional downward-pressing design, while all are anchored to the key technical points of the forward-pushing design.

This is equivalent to improving the downward pressure method, which is both a self-upgrade and a comprehensive preparation for the transformation to the forward-pushing method.

Sin 1 - Misaligned force application → Improvement 1 (change to forward force application). Sin 2 - Speed ​​loss → Improvement 2 (quasi-synchronous speed coordination).

Sin 3 - Unsteady grip → Improvement 3 (large area wrapping).

Sin 4 - Redundant Actions → Improvement 4 (Simplified and Coherent).

Sin 5 - Postural Imbalance → Improvement 5 (Upright Stability).

Sin 6 - Positioning Ambiguity → Improved Sin 6 (Precise Positioning).

Sin 7 - Poor adaptability → Improved 7 (spacing fine-tuning for better adaptability).

Do you think Su Shen has undergone a complete optimization?
These were all gradually updated and upgraded year by year.

Therefore, it did not cause any significant fluctuations.

This allows us to steadily achieve better results.

In short, Su Shen's improved downward-pressing design is itself a product of iterative progress towards a more efficient and stable transfer baton technology.

Its optimized technical framework has already formed a core prototype of a forward-looking approach, which is the fundamental premise for its rapid transformation.

In other words, this is a transformation, not a "complete overhaul".

It's just an "upgrade based on the trend".

The core underlying logic of doing this is that the underlying technical logic is highly similar, with no essential conflict, and there are no barriers to transformation.

To give just a few examples, the speed matching logic is completely consistent, with "no deceleration and near-constant speed" as the core, eliminating the waste of kinetic energy.

The core speed logic of the forward-pushing method is "parallel running at the same speed"—the receiving runner starts early, and the speed difference between the runner and the passer is ≤0.1m/s at the moment of handover, with no deceleration or pause throughout the entire process. The baton exchange is integrated into the overall running rhythm, and the core purpose is to reduce speed loss. The improved downward-pressing method has abandoned the logic of "deceleration during baton exchange and acceleration during baton receiving" in the traditional downward-pressing method. It explicitly requires "the passer to run at a constant speed without deceleration, and the receiver to start early to find the same speed." The speed difference at the moment of handover is controlled within 0.2m/s. In essence, it is "near-synchronous speed coordination," only slightly lower in speed precision than the forward-pushing method.

This high degree of overlap in speed logic means that athletes do not need to change their core habits of "starting early and handing over at the same speed" when transitioning. They only need to further compress the speed difference from 0.2m/s to 0.1m/s through training, and the transition is seamless.

In contrast, the upward flick technique's speed logic is "the baton passer slows down and flicks upward, while the receiver bends down to receive it." The speed difference at the moment of transmission can reach over 0.5 m/s, with a speed loss rate of 12%-18%, completely opposite to the "parallel at the same speed" logic of the forward push technique. If athletes switch from "slowing down coordination" to "coordinating at the same speed," they must first completely change their long-established speed habits, which can easily lead to chaotic movements and double the difficulty of the transition.

Secondly, the logic of the direction of force application is highly consistent.

All of these are based on the core principle of "horizontal forward movement," and the muscle activation memory can be directly reused.

The core logic of the forward-pushing method is "actively sending forward and receiving smoothly" - the baton passer uses his shoulder as the axis and his forearm to push the baton forward horizontally, using the momentum of running to complete the transfer without needing to exert any extra force.

The receiving runner extends their arm forward, palm facing the direction of the baton pass, and smoothly receives the baton, with the force applied in the same direction as their running. The improved downward pressing technique has upgraded its force logic from the traditional "vertical downward" to "forward baton delivery + slight downward pressure." The main direction of force is horizontal forward, with only 10%-20% of the force reserved for downward movement to prevent the baton from slipping. Its core "forward baton delivery" action is completely consistent with the forward pushing technique.

From the perspective of sports physiology, this alignment of force direction means that the athlete's muscle force memory can be directly reused: the baton passer is already accustomed to the muscle contraction pattern of "forearm extension and forward baton delivery". The activation sequence of the rotator cuff muscles and forearm flexor and extensor muscles can be converted by simply removing the extra force of "slight downward pressure" and maintaining a horizontal forward delivery.

The runner is already accustomed to the "arm extended forward, palm receiving" movement pattern. With just a slight adjustment to the palm angle, from upward to forward, muscle memory does not need to be reconstructed. Only a small correction is needed to adapt to the forward pushing force requirements.

This continuity of muscle memory significantly shortens the conversion cycle, which is a unique advantage of the modified downward pressing method.

Then the logic of gripping the rod for stability completely overlaps.

All of them are based on "large-area contact and palm wrapping", which has a high fault tolerance rate.

The core of the forward-pushing stability is "two-way fit and complete palm support" - when the baton passer passes the baton forward, the baton body fits completely against the palm of the receiving baton passer. The receiving baton passer's palm wraps around the baton body, with a large contact area, and the baton can be locked in place the moment the baton is gripped, with a drop rate of only 1%-2%.

One of the core optimizations of the improved down-press method is to eliminate the shortcoming of the traditional down-press method of "fingertip reception" and require "the receiving player to wrap the baton with a large area of ​​their palm and the passing player to place the baton in close contact with their palm when passing the baton". The contact area is increased by 2 times compared to the traditional down-press method, and the stability of the grip is greatly enhanced.

This stable logic of "large-area contact and palm wrapping" completely overlaps with the forward push style. In the modified downward press training, the athletes have already formed a conditioned reflex of "palm against the stick, gripping the stick upon touch". When switching to the forward push style, there is no need to retrain the stability of the grip, only to strengthen the awareness of "two-way active contact".

By actively pushing the baton forward and extending it forward when receiving, the passer can quickly adapt to the stability requirements of the forward-pushing style. In contrast, the traditional downward-pressing fingertip catch or the upward-lifting thumb-and-slot catch both require a lot of time to train the "palm-wrapped" grip habit, making their foundation for conversion far weaker than the improved downward-pressing style.

In this way, the action transitions are highly compatible, requiring only minor adjustments and no need to reconstruct the action system.

In addition, Su Shen had already laid a solid foundation for each step, and the training transition dimensions were highly reasonable, with low cost, short cycle, and suitability for players of different levels.

This is why the upward-sloping style was not chosen as the main handover project for Ersha Island before.

Because it is more difficult to translate upwards into this latest technological frontier.

First of all, putting everything else aside, their technical logic is completely contradictory.

The upward-striking technique, which involves "deceleration, upward force, and receiving with the tiger's mouth," is completely opposite to the forward-pushing technique, which involves "parallel movement at the same speed, forward force, and receiving with the palm." This transformation requires a complete reconstruction of technical understanding and is extremely prone to confusion.

The movement system is also completely different. In the upward pass, the baton passer raises his arm and leans forward, while the receiving baton passer bends over and bends his arm. This is completely different from the forward push, which involves "standing upright and extending the arm forward." The transition requires a complete change in body habits, and the probability of movement distortion is high.

The training foundations are completely disconnected. The core of the upward-lifting training is "flexible handover and adaptation to speed fluctuations," while the core of the forward-pushing training is "precise synchronization and stable connection." The training foundations do not overlap, and transformation requires supplementary training from scratch.

After understanding all these principles.

At least have a basic understanding.

Then you'll know what Lao Yi and Zhang Peimeng just did.

At the very moment of their handover.

Regarding the work-rest balance, eliminate the "slight downward pressure" and strengthen the "horizontal forward push". When bat-passing players train, they can attach a level to their arms to ensure that their forearms are parallel to the ground when pushing forward, gradually changing the downward pressure habit and focusing on experiencing the "using momentum to push forward" rather than actively exerting force.

Using inertia is much more effective than actively exerting force yourself.

It also saves a lot of effort.

If done well, the results will be much better.

Secondly, it's the moment the palms connect.

The baton is adjusted by the palm angle to achieve a "direct alignment". The receiving runner, Zhang Peimeng, changes from "palm up" to "palm forward". This is done by placing a mark on the palm of the runner who passed the baton, allowing the receiving runner to accurately align with the mark and fix the palm angle.

Then comes the speed transition.

Different compression speeds achieve precise synchronization.

Based on the improved downward pressure "0.5~0.2m/s speed difference", the baton-receiving athlete's starting timing is repeatedly trained by "marking the starting point + stopwatch timing".

Gradually compress the velocity difference to 0.2≤0.1m/s.

To achieve a tacit understanding and synchronized pace.

In other words, theoretically, this is where the speed drops.

It is better than the previous improved down-pressure type.

Both are twice as fast.

So this is the amazing sight you just saw.

Even though work and rest were still ranked third during the handover, it was still the most important factor.

Jamaica's teamwork was excellent; they were able to overwhelm the US team in an instant.

This is the proof.

but.

But it's still here.

We can't hold on any longer.

This is enough to explain the baton exchange in the Chinese team.

Even with Jamaica's smooth 10-point handover.

This is incredibly smooth.

At least in Mills's eyes.

That's how it is.

But it still happened.

Behold that red figure.

It must be those two red figures.

The passing of a baton.

Suddenly, they teleported to almost the same location.

It's even better because of the smoother transitions and connections between different speeds.

Zhang Peimeng's startup is smoother.

Old Zhang, who had just received the baton, was starting to get started.

They have already taken the lead over Jamaica's second runner.

That is, before Yohan Blake.

The second batter had already established a lead!
Upon seeing this, Mills couldn't help but stand up instantly.

impossible! ! !
Mills couldn't even remember how many times he'd encountered this situation while playing against this country.

He can make a bet.

When I led the Jamaican team to compete against other countries.

Such a scene has never occurred before.

Not even once.

All those shocked expressions on my face.

If we were to make an edit.

It can be said that the entire team was led by this red-clad figure.

We bought them all.

"Team China..."

"He suddenly teleported from third to first place?!"

"We...we suddenly took the lead!!!"

Hearing Yang Jian's explanation, he seemed a little confused.

All you know is what just happened.

Just how sudden was it?

Or it could be sudden baldness.
