The Su God of the Reopening of the Sports Arena

Chapter 2298 It really is a silver medal! I have to say, it's even better than a bronze medal!

But Chen Juan also relentlessly pursued them here.

That's right, it's a pursuit.

No matter how fast you can run here, Frazier.

How good is the technology?

It's come to this point.

Walk 60 meters back.

That's when it starts to decline.

A promising young athlete.

That's the rhythm.

And behind.

All of these were the stages of Chen Juan's pursuit.

Even if Frazier is in front of you.

This legendary female athlete.

That's the same.

Entering the later stages.

Adjust your center of gravity trajectory and coordinate the arm swing with the geometric golden ratio.

How to do it?
The first step is to obtain the Fibonacci parameters of the three-dimensional trajectory of the center of gravity.

矢状面（前后）：重心波动幅度从30米处的±3.5厘米降至60米处的±2.0厘米，降幅比例为3.5/2.0=1.75（接近φ）。

冠状面（左右）：重心偏移量始终≤1.5厘米，与步长（1.95米）的比值为0.0077，接近1/φ（0.236≈0.013）。

垂直方向（上下）：重心腾起高度稳定在8-10厘米，8/10=0.8（接近1/φ+0.2），确保每步的垂直能耗占比≤10%。

This trajectory control stems from the coordinated adjustment of the "trunk-pelvis-lower limbs": the forward tilt angle of the trunk linearly decreases from 40° at 30 meters to 30° at 60 meters.

The angle decreases by 2.5° for every 10 meters.

2.5/4 = 0.625 ≈ 1/φ.

The center of gravity projection point is always located in the "optimal propulsion zone" 20±1 cm in front of the foot.

The horizontal component of the force exerted by pushing off the ground accounts for more than 80%.

Then take advantage of this situation.

Push for the finish line!

especially--

The 70-100 meter range is the "ultimate competition zone" in the 100-meter sprint.

Athletes need to achieve a secondary increase in speed or minimize its decline while under conditions of accumulated fatigue.

That is the ultimate goal.

At this point, the core value of Fibonacci rhythms lies in optimizing the "resistance to decay" of biological systems through mathematical principles.

From a thermodynamic perspective, the Fibonacci ratio minimizes the "entropy growth rate" of motion parameters, reducing technical deformation caused by fatigue.

From a neuroscience perspective, the time interval of the golden ratio resonates with the "fatigue tolerance cycle" of the human motor center, extending the duration of efficient movements.

From a biomechanical perspective, the combination of lever arms and energy distribution with a φ ratio can maintain a propulsion efficiency of over 85% even when muscle contraction force decreases by 15%-20%.

and so.

Whichever it is.

They all have immense value.

All of this proves the Fibonacci rhythm.

It is a female rhythm with huge development potential.

For Chen Juan, her female physiological characteristics.

It has a high proportion of slow-twitch muscle fibers and excellent core control precision.

It is more compatible with Fibonacci rhythms.

Women are 12% more sensitive to the rhythm of movement than men, and this advantage can be amplified to 15%-20% when fatigued.

It becomes a "hidden competitive advantage" during the final sprint.

After Frazier entered the sprint zone, this woman who had been as powerful as a high-energy cannonball finally entered... a period of fatigue.

If they don't get weak soon, then we really need to get Joyner back on her feet.

But Fraser had already known that the speed was starting to decline in this area.

After running for so many years, how could she not understand her own strengths and weaknesses?

Take immediate action.

Vector optimization of ground reaction force.

During the mid-run phase, the ground reaction force exhibits the characteristics of "high horizontal component - low vertical fluctuation".

Its vector control is key to maintaining speed.

First, adjust the proportion of the horizontal force component:
Fraser's horizontal propulsion (F) stabilizes at 2.2 times his body weight.

The vertical component force (F) should be controlled at 2.8-3.0 times the body weight.

The F/F ratio reached 0.73, and the proportion of horizontal force increased by 12%.

Secondly, adjust the point of application of the force:
At this time, the center of pressure should always be located at the front 1/3 of the longitudinal axis of the foot.

The horizontal distance from the center of gravity projection point is ≤5 cm.

To ensure that the force of pushing off the ground passes through the vertical line of the center of gravity.

Only 6% of the effort is wasted.

This optimization of force stems from the coordinated exertion of force from the foot, ankle, and knee.

That is, when landing, the arch of the foot absorbs 5% of the impact force through elastic deformation.

During the support phase, the plantar flexion angle of the ankle joint increases from 30° to 45°, extending the lever arm by 0.08 meters.

Keep the knee joint slightly bent at 170°, retaining 10% of the cushioning space.

This enables the horizontal component of the push-off force to be converted into 82% of its equivalent.

According to the formula for calculating work, W = F·s.

With the same force applied to the ground, Frazier's propulsive output per step is 9% higher than his opponent's.

Provides continuous power for high-frequency steps.

It's clear that Fred's actions are in line with his biological curve.

He truly deserves to be called a legendary figure.

The overall control over technology.

And the technical adjustments at each stage.

They are all very distinctive.

The purpose is clear.

Therefore, she can consistently achieve extremely stable results every time.

This is something that ordinary talented players cannot do.

Fortunately.

No matter how much we try to control it, we've now entered her vulnerable zone.

She can forget about ever being the same as before.

He pinned Chen Juan down again.

On the contrary, it was Chen Juan.

There are opportunities here now.

She began to move into the counter-offensive zone.

Bang bang bang bang bang.

Chen Juan's step length change from 70 to 100 meters showed "controllable decay", and the decay range followed the Fibonacci sequence pattern.

70-80 meters: Stride length begins to drop.

Then move back 10 meters.

Try your best to keep your stride length from dropping by no more than 10cm.

This is done so that the ratio of decay between adjacent stages is approximately 10/7 ≈ 1.428.

It is approximately 0.88 times the value of φ.

This results in an overall attenuation rate of only 6.6%.

This is far lower than the 10%-12% average for female athletes.

The biomechanical significance of this decay mode lies in the fact that when the ratio of the decay amount to the step size approaches φ.

The loss of kinetic energy at each step.

ΔE = 1/2m(vv).

It exhibits a distribution that is "larger in the front and smaller in the back".

80-90米损失12%，90-100米损失8%。

It is highly matched with the consumption rhythm of phosphate reserves to avoid "energy depletion" collapse.

In theory, as long as it's done well enough.

This adjustment kept Chen Juan's speed at 9.3 m/s at the 100-meter mark.

80 m.

"Chen Juan is in pursuit; she's starting to chip away at Frazier's lifeline!"

Yes.

They've switched from defense to offense.

But not enough.

To offset the step size decay.

Chen Juan also needs to achieve speed compensation through the Fibonacci increment of step frequency.

The step frequency increase ratio between adjacent phases is approximately 3.6%/3.4%≈1.058.

The square root of φ is approximately 1.272, which is the reciprocal of 0.618.

This forms a "small amplitude, high frequency" compensation pattern.

The speed decay rate decreased from 1.7% to 0.5%.

The rate of decrease in decay rate is 1.7/0.5 = 3.4.

It is close to 1/10 of F=34.

This demonstrates that Fibonacci regulation can effectively slow down the decline in speed.

The last twenty meters.

Chen Juan continued to increase her bets.

Fibonacci temporal reconstruction of muscle synergistic activation.

At this point, Yang Jian and Li Tao were already excited.

The reason is very simple, just one point.

Frazier is currently in first place, and Chen Juan is in second place. They have clearly widened the gap with everyone behind them.

In that case...

Just keep it up.

That is.

A new history.

But Chen Juan couldn't think that far ahead right now; she still wanted to get closer to him.

This is an environment without pressure, but with strong opponents and exciting competitions.

It's so rare.

Just like Su Shen told her.

We must seize this opportunity.

We must seize every opportunity in major competitions.

This is a very powerful way to improve oneself.

At this moment, Chen Juan could actually feel the sound of spiked shoes behind her, but it was far away.

That would mean his silver medal

It's all settled now.

Since that's the case, why not give it a shot and see how close you are to Frazier, the current best and greatest of all time?

How much is still needed?

Just do it.

"Relay activation" of the main muscle groups.

When fatigued, Chen Juan's muscle activation pattern shifted from "single muscle group dominance" to "multiple muscle groups relaying," with the activation sequence and time intervals conforming to the Fibonacci sequence.

第一接力区（70-80米）：臀大肌主导发力（激活强度75% MVC），持续0.5秒（F=5）。

第二接力区（80-90米）：股四头肌接替主导，激活强度70% MVC，持续0.8秒（F=8）。

第三接力区（90-100米）：小腿三头肌与髂腰肌协同主导，激活强度65% MVC，持续1.3秒（F=13）。

The ratio of the duration of each stage is 5:8:13, strictly following the Fibonacci recursion.

This "relay mode" keeps the continuous working time of a single muscle group within the fatigue threshold.

Creatine kinase concentration increased by only 25% at 100 meters.

Compared to regular players, the percentage here can be as high as 40%.

The decline was quite significant.

And the more significantly your fatigue threshold decreases.

So, your ability to maintain speed at the end.

The more obvious it becomes.

Because wavelet analysis of electromyographic signals shows...

Chen Juan's muscle activation coherence at the moment of relay transition still reached 0.78.

This proves that the Fibonacci sequence ensures a "seamless transition".

90 m.

The last chance to narrow it down.

The design features an arm swing that is slightly faster than the stride frequency.

It generates a forward traction torque to counteract the "backward tendency" caused by fatigue.

Arm swing amplitude: 40° forward and backward.

The ratio of the step size to the step size is 40°/1.78m≈22.47°/m.

Approximately φ×14.

1.618×14≈22.65.

Ensure that the "power arm - resistance arm" ratio of the swing arm is stable at 1.6:1.

Furthermore, the ratio of the rotational inertia of the upper limbs to that of the lower limbs is 0.402.

It is close to 1/φ=0.382.

The sum of the angular momentum vectors of the whole body is controlled within ±0.06 kg·m/s.

Avoid energy consumption from lateral swaying.

The high-speed camera footage was reviewed after the race. At this point...

This coupling ensures that Chen Juan's torso rotation angle remains ≤2°.

It is 3-4 degrees smaller than that of the average athlete.

Reduce lateral energy consumption by 5-8J per 10 meters.

This is equivalent to an additional 2% of propulsion.

Frazier's speed dropped further at this point.

Try to get within two meters!
This was Chen Juan's only thought.

The last ten meters!
Chen Juan attempted to maintain a high level of force component ratio through vector control of force!
If we say that 70-80 meters is the horizontal component force (F) = 2.1 times the body weight.

The vertical component of the force (F) is 2.9 times the body weight.

F/F = 0.724 (close to 1/φ + 0.1).

The 10-meter race that just ended was F = 2.0 times the body weight.

F = 2.8 times body weight.

The ratio is 0.714 (close to 1/φ + 0.08).

So the last ten meters is...

F = 1.9 times body weight.

F = 2.7 times body weight.

The ratio is 0.704 (close to 1/φ + 0.07).

The ratio of F decay to F decay in all three stages is always 1:1.

It conforms to the constant decay law of F=F.

This control of force stems from the precise adjustment of the "foot-on-the-ground posture".

That is, the toes rotate inward 5° when landing.

It increases by 2° compared to the mid-run.

The pressure center is shifted inward by 0.5 cm.

This is used to prolong the duration of the horizontal component force.

Increased from 0.08 seconds to 0.09 seconds.

According to the impulse theorem (I=F·t).

At the same force value, extending the action time by 12.5% ​​can increase the horizontal impulse by 12.5%.

This partially offsets the effect of force attenuation.

92 meters, 93, 94 meters, 95 meters.

The golden distance between the point of application of the force and the projection of the center of gravity!
The final pressure-pressing stage.

The horizontal distance between COP and the centroid projection point.

Strictly controlled within the golden ratio range.

That is:
d=5厘米（70-80米）、5.5厘米（80-90米）、6厘米（90-100米）。

相邻阶段的d值比值为5.5/5=1.1、6/5.5≈1.09，接近φ的平方根（1.272）的0.87倍。

Ensure that the line of action of the force always passes through the "optimal propulsion zone" in front of the center of gravity.

The biomechanical modeling of this system by the Su Shen laboratory shows that—

When d = 5-6 cm, the proportion of wasted effort from pushing off the ground is only 7%.

What does this mean?

This means that Chen Juan can convert an additional 5% of her energy into forward momentum with each step.

During the sprint phase when muscle strength decreases by 20%.

This "precise application of force" became the key to maintaining speed.

96 meters, 97 meters, 98 meters, 99 meters...

The energy supply system ratio during Chen Juan's final sprint stage exhibited the "complementary decay" characteristic of the Fibonacci sequence.

90-100米：磷酸原25%，糖酵解75%（25:75≈0.333≈1/φ×0.87）。

The decrease in phosphagen (10%→10%) is strictly equivalent to the increase in glycolysis (10%→10%).

It conforms to the symmetrical change law of F=F.

What is the point of doing this?
The meaning is—

This ratio kept the rate of increase in Chen Juan's blood lactate concentration stable at 0.2 mmol/L/10 m.

For a regular athlete, the level is 0.3 mmol/L/10 meters.

Among them, the median electromyographic frequency, which reflects the rate of decline in muscle fatigue, slowed down by 18%.

Ensure that key muscle groups, such as the calf muscles, maintain 60% contraction efficiency at 100 meters!
That's all we'll rely on.

This adjustment matched Chen Juan's "decision load" in her central nervous system with her level of fatigue.

When fatigue intensifies, the feedback cycle will be extended, which can reduce ineffective corrections.

It saves 15% of neural energy consumption.

Meanwhile, the timing of the feedback signal intervention is always maintained at moment φ (0.618) of the action cycle.

Ensure the correction effect is maximized—for example, a support time of 0.11 seconds for 90-100 meters.

Feedback was initiated in 0.068 seconds (0.11 × 0.618).

Precisely corrects knee joint angle deviations.

Reduced from ±2° to ±1.5°.

It is based on the Fibonacci sequence.

She told Su Shen about the Fibonacci rhythm.

For the first time in history, it was presented on the international stage.

How exactly should I put it?

Specifically, that is...

Chen Juan felt her physical reserves were depleted by the end of the run...

Surprisingly, it's quite good.

I wish I had known it would be this good.

She'll be more exhausted earlier and won't have as much energy left.

but.

That's fine, after all, it's the first time I've used it in a major competition.

Chen Juan herself is already satisfied with what she has achieved.

Although in the end they still couldn't catch up with Frazier.

However, this also puts immense pressure on Frazier.

This immense pressure drove Fraser himself.

Both have made breakthroughs.

I was genuinely terrified.

With someone relentlessly chasing after you, the pressure becomes your motivation.

Fred also achieved an even more amazing result in this race.

call------

Fraser Chen Juan is on the line!
In the end, Frazier came out on top.

There's nothing we can do about it. She truly deserves to be called one of the strongest female athletes in human history. Losing to her is not shameful.

First, look at the results.

Yang Jian couldn't help but shudder.

10.69.

Good guy.

He actually managed to break 10.70 seconds in a major competition.

And if I remember correctly.

This result also became Frazier's new personal best.

This surpasses the 10.70 seconds he set in Kingston last year.

Moreover, the score of this shot was quite impressive.

That gun at least had a wind speed of 0.6 meters per second.

This shot is a gamble.

I go.

It's directly negative.
-
0.3 meters per second.

In other words, this shot demonstrates a raw skill level that is at least 0.05 points higher than the personal best achieved last year.

Of course, historically, she actually ran a time of 10.71 seconds for that shot.

And that was only because the later contestants weren't performing well.

The second place finisher only had a time of around 10.95 seconds.

She pushed him more than two meters.

There's definitely no pressure here.

Without pressure, there is no motivation.

Now Chen Juan is chasing after him.

This would definitely give her more motivation than she would have on the original timeline.

She had the potential to break her limits in this match.

Chen Juan gave it to her here.

The finishing touch.

This directly allowed Frazier to break the 10.70-second barrier.

This also allowed her to surpass her best performance in her previous life.

She achieved what she had always longed to do: reach 10.60+ in the field.

When Fred saw the results, he was overjoyed.

Breaking personal records and winning a major competition gold medal.

Moreover, this record was achieved in a major competition.

I really don't know what else there is to be dissatisfied with.

Frazier.

This gold medal includes this 10.70-second opening.

To secure her place in history.

They also climbed another step.

An unshakeable legend of a woman.

Even in the grand scheme of history, it stands as a rock-solid presence.

I was a little careless.

She will definitely turn the tables on you.

Just as everyone was marveling at another score of 10.60+.

Yang Jian's voice brought many people back to their senses.

This isn't just about Frazier.

Our own athletes.

It's here too.

First, look at the results.

Yang Jian immediately raised his voice.

A proud declaration—

10.85!

Chen Juan: 10.85!

He ran a time of 10.85 seconds despite the headwind.

This shot, let alone altitude.

If only the wind speed were better.

They all have a chance to create new miracles.

but.

It doesn't matter if there's no wind, because they don't have any wind, and neither do the others.

This is a silver medal.

That's enough.

This announcement declared that Chen Juan not only completed her task this year, but exceeded it.

There is no doubt that a silver medal is more valuable than a bronze medal.

Regarding her historical status.

It is also more stable.

"Second place!"

"silver medal!"

"We actually won a silver medal in the women's 100 meters here!!!"

"A new history has begun!!!"

"Chen Juan quietly made history; she fulfilled her pre-race promise and set a new Asian women's sprint record!!!"

"It wasn't a bronze medal, it was a silver medal! Second place!!!"

Stop talking about him.

Chen Juan looked at it herself.

They couldn't help but feel a little restless.

My eyes are moist.

I almost burst into tears.

silver medal.

He has once again broken the record for the highest altitude in Asia.

And there's something strange about it.

That's the feeling I didn't have when I won the bronze medal.

When I won the bronze medal, I hadn't even thought about winning the gold.

But after winning the silver medal.

do not know why.

Suddenly, that gleaming golden medal appeared.

That's when it started to appear in Chen Juan's mind.

There's no way to avoid it.

You can't shake them off no matter how hard you try.

P.S.: Extra chapter added! Please vote!
Let's make plans again tomorrow...
