The Su God of the Reopening of the Sports Arena

Chapter 2296 Fibonacci Sequence! New Enhancement Tool for Female Athletes!

This person is none other than Chen Juan from lane 6.

Precision start control dominated by articulated boom technology.

Yes, he has enough to say this year—

My mastery of the articulated arm technique has reached a level of precision.

Improve again.

Chen Juan's flexion-arm initiation technique this year is built on a "coordination-first" neuromodulation model.

Its core innovation lies in the arm swing posture with both elbows bent at 120°.

This posture reduces the rotational inertia of the upper limbs by 28%.

The angular velocity of the swing arm reaches 300°/second.

The resulting backward reaction force is transmitted through the shoulder to the torso, propelling the center of gravity forward by 18 centimeters in 0.3 seconds.

This is based on the principle of minimizing rotational inertia.

The elbow flexion angle directly affects the rotational inertia of the upper limb—and 120° is the optimal solution for balancing rotational inertia and range of motion under Chen Juan's current physiological condition.

The biomechanical simulations given to her by Su Shen's lab showed:

When the angle is less than 120°, the forearm is too close to the torso. Although the moment of inertia is reduced by 35%, the swing amplitude is limited, resulting in insufficient forward driving force.

When the angle is greater than 120°, the forearm is far away from the torso, the moment of inertia increases by 18%, the energy consumption of the swing arm increases by 25%, and the air resistance coefficient increases by 12%.

When bent at 120°, the forearm and upper arm form an "obtuse triangle" structure, which shortens the radius of rotation from the hand to the shoulder joint by 28%, from 65cm to 47cm.

It also retains 85% of the swing arm amplitude.

The moment of inertia was reduced to 62% of that in the straight arm posture.

The energy required for the swing arm is reduced by 31%.

This energy efficiency is crucial for the start-up phase—upper limb arm swing accounts for 22% of the total energy consumption in the first four steps of the start-up.

A 120° bend can reduce this energy consumption by 15%.

This allows more energy to be allocated to pushing off the ground with the lower limbs.

At the same time, compare the use of levers in the Okabarre.

Chen Juan is the real expert.

In the case of a curved arm, the 120° bend is optimized by adjusting the lever arm-angular velocity relationship to improve the power of the swing arm.

The lever arm length of the biceps and triceps at 120° is 30cm, which is in Chen Juan's current "sweet spot" for exertion.

The torque generated by muscle contraction reaches 35 N·m.

30 N·m at 90° and 28 N·m at 150°.

The angular velocity of the swing arm reaches 300°/s.

Combining the torque advantage, the swing arm power reaches 175W.

The power boost translates into significant forward driving force—when bent at 120°, the reaction force generated by the swing arm is transmitted to the torso through the shoulder.

This increases the forward velocity of the center of gravity by 0.3 m/s.

It increased from 3.2 m/s to 3.5 m/s.

The time taken to go from 0 to 10 meters has been reduced by 0.02 seconds.

A more advanced muscle coordination mechanism adapted to female physiological characteristics.

You said that Stewart and Ahore also adopted a synergistic mechanism adapted to female physiological characteristics?
I'm sorry, even though we took all of them.

There are highs and lows.

anything.

They say there are no different classes.

the fact is.

Everything has its own hierarchy and distinctions.

There are different levels of social class.

Everyone knows this perfectly well.

Chen Juan is a typical example.

Differentiated adaptation of muscle strength!

Female athletes have 25%-30% lower upper limb absolute strength than males, and 120° bending helps to adapt to this characteristic by lowering the "strength requirement threshold".

This means that the load on the agonist muscles is reduced.

To achieve a 60% MVC contraction strength in your biceps at 120°, you only need to achieve that.

The target swing speed can then be achieved.

Synergistic muscles are highly engaged.

The activation intensity of the anterior deltoid and pectoralis major at 120° is increased by 10%.

The forward drive force is supplemented by the "shoulder forward movement" to compensate for insufficient upper limb strength.

Su Shen Lab's surface electromyography data showed that female athletes who used a 120° bent arm experienced a 5% decrease in fatigue level of their upper limb muscle groups and a 18% decrease in the median frequency of electromyography compared to what they could normally achieve, and were lower than athletes with straight arms.

It is more conducive to the stability of the swing arm in the later stage.

In addition, there is the optimal utilization of muscle elastic potential energy.

A 120° bend puts the upper limb muscles, especially the biceps and tendons, in an "optimal pre-stretch state".

Based on the muscle length-tension relationship.

The elastic deformation of the tendon reached 3%.

This "muscle-tendon" synergistic energy storage mechanism is particularly important for female athletes with smaller muscle volume—it can compensate for the lack of active contraction force through elastic potential energy, achieving a "force-assisted elasticity" activation mode.

That's all it takes to completely overwhelm Stuart and the others.

You said Freeman follows the rhythmic pattern of the Fibonacci sequence?

I'm sorry.

Chen Juan's change.

It is more in line with expectations.

The intrinsic connection between the Fibonacci sequence and the rhythm of biological movement is that the core characteristic of the Fibonacci sequence 1, 1, 2, 3, 5, 8, 13 is that the ratio of two adjacent terms approaches the golden ratio φ≈1.618.

This ratio is widely present in the rhythmic regulation of biological movement, such as gait cycle and limb swing amplitude.

From an evolutionary biology perspective, movement patterns that follow the Fibonacci rhythm minimize energy loss.

When the ratio of adjacent action parameters is φ, the system's resonant frequency matches the biomechanical characteristics, and the energy transfer efficiency is improved by 20%-30%.

In the initial phase of a sprint, the Fibonacci rhythm manifests itself as follows:
Spatial dimension: The ratio of adjacent increases in parameters such as step length and swing arm amplitude is φ;
Time dimension: Step frequency, adjacent ratio of muscle contraction cycles is φ;

From a mechanical perspective: the increasing ratio of the force exerted on the ground and the arm swing torque approaches φ.

The quantification of Fibonacci rhythm in Chen Juan's initiation technique is reflected in...

The golden ratio of step size increase.

Chen Juan's step size changes during the initial phase strictly followed the Fibonacci increasing pattern.

The first step is 0.9 meters long, the second step is 1.0 meter, the third step is 1.1 meters...

相邻步长的比值为1.0/0.9≈1.11，1.1/1.0≈1.10，1.2/1.1≈1.09。

Although it is not directly equal to 1.618.

However, when combined with step frequency parameters, a composite golden ratio is formed.

The step size × step frequency increment ratio is 1.62.

0-10米速度5.2m/s，10-20米8.4m/s，8.4/5.2≈1.615。

It closely matches the value of φ.

This composite golden ratio of "step length-step frequency" ensures that Chen Juan's kinetic energy increment is evenly distributed with each step.

Avoid energy loss caused by sudden speed changes.

It conforms to the core characteristic of the Fibonacci sequence: "smooth energy transfer".

The ratio between the external bending arm angle and the swing arm amplitude.

The 120° bend in the elbows and the arm swing amplitude form a golden ratio geometric relationship.

When the elbow is bent at 120°, it corresponds to 1/3 of the circumference angle, and the forearm swing angle is 68° when swinging the arm.

120° × 0.566 ≈ 68°.

0.566 is 1/φ.

The ratio of shoulder joint range of motion to elbow joint range of motion is 1.63.

肩关节摆幅85°，肘关节摆幅52°，85/52≈1.63。

It is close to the value of φ.

From a sports anatomy perspective, this proportion creates a "nested lever system" in the upper limbs—with the shoulder joint as the large lever.

Large swing amplitude, slow speed.

The elbow joint is a small lever.

Small swing amplitude and fast speed.

The two are coupled in a golden ratio, which enables the linear velocity at the end of the swing arm to reach 5.8 m/s.

It is 12% faster than non-golden ratio postures.

When the neural feedback cycle is 1/φ of the action cycle, the feedback signal can intervene and correct at the "golden moment" of action execution, at 0.618 of the action cycle, thereby improving the adjustment efficiency.

Chen Juan's electromyography signals showed that the neural commands for each step length adjustment were issued at 0.62 during the support phase.

0.18 seconds × 0.62 ≈ 0.11 seconds.

It closely matches the Fibonacci timeline.

This resonance mechanism reduces the "trial and error cost" of neural modulation, reducing the energy consumption for correcting the initiation action by 25%.

Furthermore, by combining this with the Fibonacci rhythm, the rate of increase in energy metabolism can be controlled.

Achieving a dynamic balance between energy supply and energy consumption. Chen Juan's phosphate progeny consumption rate during the start-up phase exhibited a Fibonacci increase.

That is, for meters 1-10: 0.8.

第11-20米：1.3，0.8×1.625。

第21-30米：2.1，1.3×1.615。

The increasing ratio is close to φ.

This metabolic rhythm closely matches the body's phosphagen reserve depletion curve—avoiding excessive consumption in the early stages that could lead to energy depletion later on, and also preventing a slowdown in speed due to initial conservatism, which aligns with the mathematical essence of the Fibonacci sequence: "balance between growth and stability."

In addition, Su Shen helped her adjust:

Based on the fact that women tend to have wider pelvises.

The "wave-like transmission" of core muscle activation.

From the rectus abdominis to the obliques.

It naturally follows the Fibonacci sequence.

The ratio of the stabilizing torque of a 120° bent arm to the stabilizing torque generated by the core muscle group is 0.63, which is close to 1/φ.

This naturally creates a synergistic resonance between the upper limbs and the core.

The people mentioned above only fit one aspect.

Chen Juan's side.

But almost with Su Shen's help.

It encompasses almost all aspects.

The 120° elbow flexion posture, step length, and arm swing parameters in Chen Juan's bent-arm starting technique conform to the Fibonacci sequence through the following mechanism.

For example, at the geometric level: the ratio of the elbow joint angle to the arm swing amplitude approaches 1/φ, forming a highly efficient lever system.

For example, in terms of time: the resonance between the neural feedback cycle and the action cycle conforms to the Fibonacci time ratio.

For example, at the energy level: the rate of increase in metabolic rate is close to φ, achieving a dynamic balance between energy supply and energy consumption.

Su Shen told her that this adaptability is essentially the "optimal selection" of biological movement in response to the mathematical laws of nature.

Especially for female athletes with weaker muscle strength but higher coordination precision, the Fibonacci rhythm can maximize the efficiency of technical execution, providing theoretical support from both mathematical and biological dimensions for the personalized design of women's sprint techniques.

although.

Chen Juan didn't quite understand what Fibonacci increments, Fibonacci rhythms, or Fibonacci sequences meant.

She even thought of the three words Fibonacci.

They're all very tongue-twisting.

I have no idea how to say it.

However, the principles and plans were well-organized under Su Shen's arrangement.

At times like these, it doesn't matter if the athletes don't quite understand.

It would be best if you could understand it.

I don't understand, but it's fine as long as I do it this way.

Isn't that what Bolt and his teammates are like?
You'll gradually understand it as you do it.

That's it.

After all, for the people of Ersha Island, in addition to running, daily learning and acquiring various scientific knowledge is essential.

Otherwise, don't say you're someone who runs on Ersha Island.

That's it. Although both America and European laboratories have discovered the applicability of the Fibonacci sequence to sprinting, especially women's sprinting.

But how exactly do you do it?
That's just the tip of the iceberg.

He doesn't resemble Su Shen at all.

It comes as a complete system.

Moreover, these are theoretical details that have been proven decades later.

Includes extension packages.

He included them all.

How can you compare to others?
Chen Juan started it.

The Fibonacci hierarchy of muscle activation timing!

Chen Juan's muscle activation sequence during the initiation phase exhibited a hierarchical characteristic resembling the Fibonacci sequence, forming a "1-2-3-5" activation chain from the core to the periphery.

first step.

Level 1: The transverse abdominis muscle, as the earliest muscle group to be activated, is activated 0.01 seconds after the command, and its contraction intensity reaches 40% MVC, providing a rigid foundation for the trunk.

The second step.

Level 2: After 0.02 seconds, the gluteus maximus and quadriceps femoris are activated simultaneously, forming a coordinated force unit between the hip and knee joints.

third step.

Level 3: At 0.03 seconds, the triceps surae, tibialis anterior, and iliopsoas muscles are activated in sequence, responsible for ankle joint control and lower limb swing.

Step 4.

Level 4: At 0.05 seconds, the biceps brachii, triceps brachii, anterior deltoid, pectoralis major, and latissimus dorsi muscles move at Fibonacci intervals.

0.002 seconds, 0.003 seconds, 0.005 seconds.

Start them sequentially to complete the articulated boom start process.

This "1-2-3-5" activation quantity pattern is utilized.

It closely matches the recurrence relation of the Fibonacci sequence F=F+F.

This allows muscle power to be transmitted in a "wave-like" manner from the core to the extremities.

The energy loss rate is controlled within 8%.

Non-hierarchical activation mode loss reaches 15%.

Three more steps.

Bang bang bang.

Chen Juan even followed closely behind Frazier.

She was also the only female athlete who wasn't immediately left behind.

This shows that Frazier has done a great job.

This also shows that Chen Juan was under the guidance of Su Shen.

The system is powerful.

Acceleration zone.

Fred was still leading the way.

Chen Juan, on the other hand, relies on the golden ratio of the contraction-relaxation cycle.

The ratio of contraction to relaxation time for a single muscle follows the golden ratio.

For example, the quadriceps femoris.

The contraction time during the support phase is 0.11 seconds.

The relaxation time during the airborne phase is 0.07 seconds.

The ratio of the two is 1.57, which is starting to approach φ=1.618.

When the biceps brachii is flexed and swung, the contraction time is 0.08 seconds and the relaxation time is 0.05 seconds, with a ratio of 1.6.

It perfectly conforms to the golden ratio.

According to the principles of muscle physiology, the sarcoplasmic reticulum Ca recovery efficiency is highest when the contraction-relaxation ratio is φ.

It can prevent muscle rigidity caused by calcium accumulation, and increase the retention rate of the next contraction force by 10%.

This is crucial for Chen Juan's high-frequency muscle contractions during the initial stage, ensuring that the muscle groups can maintain output stability when repeatedly exerting force in a short period of time.

Then, the Fibonacci distribution model of biomechanical energy flow is used.

From the hip joint to the ankle joint, the propulsive energy contributed by each joint follows a Fibonacci ratio distribution.

髋关节提供总能量的55%，F=5，占比5/9≈55%。

膝关节33%，F=3，3/9≈33%。

踝关节12%，F=2，2/17≈12%。

The ratio of the three is close to 5:3:2, which conforms to the energy distribution logic of the Fibonacci sequence, which is "major joints dominate and minor joints assist".

This allocation, combined with Chen Juan's 120° bent-arm posture, creates cross-limb coordination—upper limb joints, shoulder:elbow = 5:3.

It perfectly matches the energy distribution ratio of the lower limb joints, with the hip:knee ratio being 5:3. This ensures that the energy flow throughout the body forms a "symmetrical golden ratio".

Reduce lateral swaying caused by energy imbalance between the left and right limbs.

ten meters.

In the bent-arm starting posture, the ratio of the elastic potential energy (E) stored in Chen Juan's muscles and tendons to the converted kinetic energy (E) is 0.618 (1/φ).

When Chen Juan started, the elastic potential energy stored in her hamstrings and Achilles tendon was 180J, which was converted into kinetic energy of 291J.

180/291≈0.618.

The ratio of the elastic potential energy (35J) of the biceps brachii tendon in the upper limb to the kinetic energy of the arm swing (57J) is 0.614, which is also close to 1/φ.

According to the law of conservation of energy, when E/E=1/φ, the entropy increase of energy conversion is minimized, that is, the amount of wasted heat energy is minimized.

This improves Chen Juan's energy utilization efficiency by 18% compared to conventional startup techniques.

It can still maintain 90% of its initial explosive power at 30 meters in the acceleration zone.

Twenty meters.

"The core value of Fibonacci rhythm lies in achieving cross-system resonance of 'neuromodulation-muscle contraction-energy metabolism,' which manifests as a three-level coupling in your activation technique..."

The words Su Shen had said to her during winter training seemed to echo in her mind.

第一时间尺度耦合：神经冲动周期（0.016秒）、肌肉收缩周期（0.18秒）、能量代谢周期（0.3秒）的比值为1:11:19。

Approximate Fibonacci sequence 13:21.

This forms a nested cycle of "fast-paced nerves - medium-paced muscles - slow-paced metabolism".

Second spatial scale coupling: The ratio of the rotational inertia of the upper limb to that of the lower limb is 0.389 (close to 1/φ=0.382).

This ensures that the distribution of rotational inertia throughout the body presents a "golden ratio balance," preventing the body from rotating during startup.

The third intensity scale coupling: the increasing ratio of nerve impulse intensity, muscle activation intensity, and energy output intensity is 1.62, which conforms to the φ value.

Ensure that the intensity of "signal-action-energy" is matched, and there is no overload or underload phenomenon.

Why should Chen Juan be in charge of this system?
The main reason is that Su Shen knows that the female pelvic structure has evolved to have a wider lateral dimension to adapt to childbirth.

This requires that the activation of the core muscle groups must follow the "progressive golden ratio".

For example, the activation sequence of the transverse abdominis muscle → rectus abdominis muscle → oblique abdominis muscle.

Otherwise, it could easily lead to core instability.

This evolutionary pressure has made women's perception of Fibonacci rhythms 20% more accurate than men's!

Secondly, women have 10%-15% more body fat reserves than men.

However, due to weaker muscle strength, evolution has led to the adoption of a "low-energy consumption - high coordination" movement pattern.

The Fibonacci rhythm is the mathematical embodiment of this pattern—distributing energy through the golden ratio.

This reduces energy consumption per unit distance by 12%, which perfectly matches the energy-saving characteristics of Chen Juan's startup technology.

So it would be a real waste not to learn this.

In addition, with her own complete system and plan, Chen Juan could get straight into the swing of things and avoid taking detours.

So what are you waiting for?

Previously, Chen Juan's skill level and ability were not sufficient to cultivate this system.

Now Su Shen thinks it's okay.

Then.

After more than half a year of training.

This is the ultimate secret behind Chen Juan's continuous breakthroughs and further progress this year.

It was also the secret that made Li Xuemei and the others feel their brains tremble simultaneously after hearing it.

no way.

Say it.

I don't understand at all.

When they first heard these words.

I doubt she's much better off than Chen Juan.

This kind of thing is only just beginning to be proposed and used in the field of track and field abroad.

It's perfectly normal not to understand.

Therefore, in terms of detailed planning and overall direction control, we can only follow Su Shen's lead.

It can't be adjusted at all.

Fortunately.

Su Shen won't make mistakes in this regard.

It possesses absolute correctness decades from now.

This allowed Chen Juan to withstand the pressure.

I've practiced to this level.

Bang bang bang.

Thirty meters.

To be honest.

At this point, the overall situation of the game had already been divided into groups.

Frazier and Chen Juan are in the lead.

The rest.

Let's put together another nice table.

Poor Okabaré, that unlucky guy.

Chen Juan gave him another beating.

Of course, this wasn't Chen Juan deliberately setting her up.

It was entirely because of the moment Okabaré looked up at Chen Juan.

The whole person is not well.

Didn't expect that at all.

Chen Juan also has long legs.

They were even able to take it a step further.

This sets her pace.

Unconsciously, I was also affected.

Just like Yang Jian is saying now—

"The race begins, with Frazier taking the lead, but Chen Juan is close behind!"

"Fraser is accelerating, and Chen Juan is accelerating as well, but they still haven't been left behind!"

"On the contrary, they have already left everyone else behind!"

Indeed, they left everyone behind.

This type of race starts in the acceleration zone.

Or.

From the startup phase.

That already set the tone.

Chen Juan vs. Frazier.

See here.

Li Xuemei suddenly realized why Chen Juan was so insistent; Su Shen had only said one sentence in the interview.

damn it!
This actually works???

Has it really become a two-horse race?
If it really comes to that.

Let's not talk about the gold medal.

Even if we can't win
That's... second place.

This is Su Shen.

He's probably even more of a prophet than Moses.
