The Su God of the Reopening of the Sports Arena

Chapter 2292 Be a little bolder, maybe the OW level isn't so difficult.

The third group came up.

This group was also very intense.

Fraser, Chen Juan, Stewart, Alexander Anderson, Soumare, and others.

They wanted to break through.

You also have to break the eleven-second barrier.

It is possible.

"The third group of the women's 100m semifinals at the Moscow World Championships featured five top athletes with distinct styles," said Yang Jian. "Jamaican star Fraser is known for her 'explosive power and frequency dual excellence,' with her start reaction time consistently between 0.135 and 0.140 seconds. Chinese athlete Chen Juan demonstrated her unique rhythm advantage during the acceleration phase with her 'bent arm start system.' Stewart employed a 'segmented energy distribution strategy,' resulting in unparalleled endurance in the later stages. Alexander Anderson achieved efficient conversion between stride length and frequency through 'elastic push-off technique.' French athlete Soumaré reduced energy consumption during the middle stages with 'aerodynamically optimized posture.'"

"As for who will have the last laugh, we'll have to see how they perform in the early hours of this match."

set.

An electronic command was given.

Everyone, get ready to start.

Bang————————

Fraser adopted an aggressive starting block setup—the front starting block was 1.25 meters from the starting line, and the rear starting block was 1.1 meters from the front starting block, creating a smaller push-off angle.

This setup suits its height of just over 1.5 meters – the shorter lower limbs, through a more compact power exertion zone, increase the horizontal component of the push-off force to 82%.

In its preparatory position, the hips are 15 centimeters higher than the shoulders, which puts the quadriceps and gluteus maximus in the best pre-stretch state. According to the muscle length-tension relationship, this posture can increase the initial push-off force by 18%.

After the starting gun fired.

She started with a reaction time of 0.138 seconds.

The first two steps are 0.85 meters and 0.95 meters in length, respectively.

This ultra-high frequency activation strategy is based on the physiological characteristic that its fast-twitch muscle fibers account for 78%, and generates explosive power by rapidly activating type II muscle fibers.

It is worth noting that her arm swings employ an "asymmetrical high-frequency arm swing"—the left arm swings forward to chin height, while the right arm swings backward past the hip.

The reverse torque generated by this arm swing method forms a mechanical balance with the force of the lower limbs pushing off the ground.

Keep the body's center of gravity offset within ±2 cm.

As a runner who relies on late-race power, Stewart employs a "delayed burst" starting strategy. His starting blocks are set relatively conservatively, 1.35 meters before and 1.25 meters after, aiming for more stable initial support. While his reaction time of 0.145 seconds isn't outstanding, he uses an "isometric acceleration mode" after the start: the first four strides are all 1.1 meters long, maintaining a stride frequency of 4.8 steps per second. This strategy, by extending the push-off time (0.25 seconds per step), activates more slow-twitch muscle fibers, conserving explosive power for the final sprint.

In terms of arm swing, she uses "synchronized arm swing technique": the swing amplitude of both arms is reduced by 15% compared to the conventional method, but the swing frequency is strictly synchronized with the lower limb stride frequency (1:1). This design reduces the energy loss in the start phase to 8%, which is significantly lower than the 12-15% of aggressive athletes.

Chen Juan's bent-arm start technique demonstrates her technical intelligence as an athlete.

The starting blocks were also meticulously designed.

The starting blocks are spaced 1.3 meters (front) to 1.2 meters (back) in a balanced layout, with an 8° angle to the center line of the track, which optimizes the body's entry angle while ensuring the power of the push-off.

In its preparatory stance, the torso is leaning forward at a 45° angle, which reduces air resistance and places the center of gravity 10 centimeters in front of the feet, creating a stable foundation for acceleration.

At the moment of activation, the curved arm explodes.

She sprang out with a reaction time of 0.142 seconds, using a "bent arm acceleration model" for the first four steps: 0.9 meters for the first step, 1.0 meters for the second step, 1.1 meters for the third step, and 1.2 meters for the fourth step.

This acceleration method avoids premature fatigue by gradually activating the transition from slow-twitch muscle fibers to fast-twitch muscle fibers.

Its ankle dorsiflexion angle reaches 35° when pushing off the ground, and the pennate structure of the triceps surae muscle enables it to generate a pushing force of 3.2 times its body weight in a 0.2-second push-off time, achieving efficient energy conversion.

The three of them rushed out quickly.

At most, there was an American athlete named Anderson accompanying him.

The rest of the people.

It doesn't matter if you're Soumare or Yvette Lalova-Collio.

Or perhaps it's Xenica Ferguson.

The era of capitalism is over.

They can no longer keep up with the pace of progress in this era.

Frazier is Frazier after all.

Even now, Chen Juan's bent-arm start is becoming more and more proficient.

It still couldn't withstand Frazier's activated divine power.

This woman is inhuman.

This acceleration mode relies on its powerful phosphagen energy supply system—providing high-energy phosphate bonds within 10 seconds through CP breakdown, supporting high-intensity muscle contractions.

It's not just this talent.

And muscles.

In addition, its hip joint extension reaches 165° during the acceleration phase, and the quadriceps contraction speed reaches 8.5 m/s, keeping the horizontal acceleration at 3.2 m/s.

In the fifth step, she adopted a "flexible, energy-saving posture":
The supporting leg is bent at the knee joint to 140°.

The ankle joint is dorsiflexed at 40°.

To form an energy storage structure similar to a spring.

According to Hooke's Law, this posture increases the muscle's elastic potential energy storage by 22%, providing additional power for subsequent acceleration.

Stewart strictly controlled energy output during the startup phase, employing a "gradient acceleration strategy".

The stride length increase is controlled at 0.1 meters, and the stride frequency is increased slowly.

This causes the body's kinetic energy to increase linearly.

The quadriceps muscle maintains an activation intensity of 75% MVC during acceleration, avoiding premature depletion of phosphagen reserves.

If there were plantar pressure sensors, it would show that her center of gravity projection always remained 15 centimeters in front of the center of her foot, ensuring that the horizontal component of her pushing force remained above 78%.

American athlete Anderson gradually reduced his forward lean angle from 45° at the start to 35°, keeping his center of gravity in an ideal area 20 centimeters in front of his body, ensuring that the force of each step was effectively converted into horizontal speed.

Typical American technology.

Upon landing, the ankle joint is first passively dorsiflexed to absorb the impact.

Then, the plantar flexion generates a pushing force.

It is full of aggression.

Chen Juan started with her arms bent, using a dual-drive system.

Upper limb drive: At the moment of initiation, the bent arm swings at an angular velocity of 300°/second, generating a backward reaction force.

According to Newton's third law, this force is transmitted through the shoulder to the torso, assisting the body in leaning forward.

Lower limb drive: The simultaneous lower limb push-off motion has a push-off angle of 45° and a push-off force of 3.2 times the body weight.

It forms a mechanical coupling with the swinging of the upper limbs.

Shift your body's center of gravity forward to the ideal position 18 centimeters in front of your feet within 0.3 seconds.

Because of the bent-arm start.

how to say.

Even though she is very tall.

Yet, they were able to directly climb to second place here.

Second only to the female-led powerhouse, Freyt.

Entering the acceleration phase.

American athlete Anderson didn't handle this spot well enough, and there was some stagnation.

This allowed Stuart to catch up with her immediately.

Although Stuart is older than him.

The performance here.

It is indeed better and more experienced.

But this is what the audience is watching.

Only Frazier and Chen Juan remained.

In order to counter Frazier.

Chen Juan made adjustments here.

The first phase is the acceleration phase, where the bent-arm start provides the mechanical basis for Chen Juan's stride extension.

Due to the increased swing torque of the upper limbs (25% greater than that of a straight arm), the lower limbs can obtain a greater reaction force when pushing off the ground.

In terms of energy allocation, Chen Juan's current bent-arm technique reduces the energy loss of upper limb swinging, allowing more energy to be used for lower limb acceleration.

Moreover, Chen Juan's phosphate consumption rate during the acceleration phase was 15% lower than that of athletes who used a straight-arm start.

This preserves crucial energy reserves for the final sprint.

In addition, precise control of the center of gravity trajectory.

The bent-arm start helped Chen Juan achieve a low center of gravity and highly stable acceleration posture.

Its torso leans forward at a 48° angle at the start and smoothly transitions to 35° after seven steps.

The center of gravity should always be projected in the golden area 15-20 centimeters in front of the feet.

This posture control benefits from the "torque balance effect" generated by the curved arm.

When the arm swings backward, the counterclockwise torque generated cancels out the clockwise torque generated by the lower limb pushing off the ground.

The lateral deviation of the body should be controlled within ±3 cm.

Thus, Frazier remained in the lead.

However, the lead is not significant.

Chen Juan kept biting down from behind.

Perhaps for Yuan Qiqi or even Wei Yongli, the ability to use multiple guns or dual guns is insufficient.

But what about Chen Juan?
It's not a big deal.

At least for her, she already possesses the ability to use both pistols to their fullest potential.

All for the sake of winning a medal in the competition.

We won't let ourselves fall apart in the final after being exhausted in the semifinals.

look up.

Enter the mid-race phase.

This "high-frequency small steps" strategy is biomechanically adapted to his height.

The shorter lower limbs reduce airtime through rapid swinging, achieving an airtime/support ratio of 0.9:1 and reducing air resistance.

Its swing arm technology has reached its pinnacle.

The range of motion of the arms is extended to 95% of the shoulder joint's range of motion.

The oscillation frequency and the step frequency form a supersynchronous relationship of 1:1.1.

The forward driving force generated by this swing arm can increase speed by 2-3%.

Don't underestimate this small amount; for a world-class athlete like Fred, it's significant.

Every improvement, however small, is invaluable.

I would never think it's too little.

In addition, there's the aspect of attitude control.

Her torso remained at a forward tilt angle of 28°.

The head and spine are in a straight line.

This reduces the area exposed to the wind.

Enter the mid-race phase.

Frazier is even faster.

It was like a miniature rocket.

Fraser truly deserves to be called a legend in women's programming.

Her ability to maintain her peak performance for so long is definitely not just due to her physical attributes. Her constantly evolving and improving techniques are the core reasons why she has been able to delay aging and remain competitive even as she gets older.

can.

Chen Juan was no pushover either.

Adjust the swing arm.

It switches to a "semi-bent arm swing" mode, adjusting the elbow angle from 120° at the start to 140°.

The scientific principle underlying this change in angle is—

Aerodynamic optimization: The curved arm effectively reduces the frontal area.

Compared to traditional arm swinging, the semi-bent posture allows the upper limbs to form a smoother streamline during the swinging process, reducing the drag generated by air turbulence.

According to the principles of fluid mechanics, changes in the curvature of an object's surface can affect the points where airflow adheres to and separates. A semi-bent arm allows airflow to adhere more closely to the limb's surface, delaying airflow separation and thus reducing pressure drag.

This posture adjustment reduces her air resistance coefficient by approximately 15%-20% during high-speed movement.

At a running speed of 8-9 meters per second, approximately 8%-12% of the energy consumed in overcoming resistance can be saved.

Then comes the muscle working mode switching.

The 140° elbow angle puts the biceps and triceps in a more efficient range of motion.

During the swinging motion, the muscles do not need to maintain excessive contractile tension, but instead use the elastic potential energy of the tendons and joints to assist the movement.

When Chen Juan swings her arm forward, her biceps brachii first performs an eccentric contraction to control the swing speed, and then quickly contracts concentrically to complete the forward swing.

When swinging backward, the triceps brachii dominates a similar "eccentric-concentric" contraction pattern.

This elastically driven contraction method reduces energy consumption compared to the sustained high-intensity isometric contraction of muscles during straight-arm swinging.

A two-pronged approach.

"Chen Juan vs. Frazier!"

"I believe this is what the final will look like!"

"Two people of different sizes, chasing each other, it's quite a lively scene!"

A lightning-fast burst of speed. Here at Frazier.

That might not be enough to control Chen Juan.

An athlete of her size.

Extreme speed is bound to be not too fast.

Otherwise, she wouldn't be Frazier.

That is Joyner.

Chen Juan kept waiting.

Only after it was over did she suddenly... go all out.

Chen Juan's stride length and stride frequency control during the run demonstrated a sophisticated technical logic.

First, she stabilized her stride length at 1.9-1.95 meters.

This value is not randomly set, but is based on the golden ratio relationship between the height of the body's center of gravity and the length of the lower limbs.

From a biomechanical perspective, the energy conversion efficiency is highest when the ratio of stride length to center of gravity height is in the range of 1.0-1.05.

By precisely controlling the hip joint extension range, approximately 160°-165°, and the knee joint extension angle, approximately 175° at the moment of pushing off the ground, Chen Juan maintains the horizontal component of the force exerted on the ground in each step at 78%-82%.

Ensure that energy is effectively converted into driving force.

When the brain sends the command for the lower limbs to push off the ground, it simultaneously triggers the upper limbs to swing, and the swing rhythm is slightly faster than the stride frequency, producing a forward traction effect.

This is to ensure that one's stride frequency and arm swing frequency form a fixed ratio of 1:1.1.

Research from the Sussex Lab shows that this "advanced arm swing" strategy can increase the forward shift of the body's center of gravity by 5%-7%, helping to maintain inertia during high-speed movement.

Maintain speed.

Maintain at lightning speed!
Swing arm parameters locked!

The elbow angle of the semi-bent arm swing is stable at 140°±3°, and the arm swing frequency and step frequency always maintain a fixed ratio of 1:1.1.

The fluctuation in activation intensity of the biceps and triceps was controlled within ±8%.

Ensure the forward driving force generated by the swing arm is stable.

Through automatic regulation via the spinal reflex arc, when muscle fatigue leads to a decrease in contractile force, the nervous system preferentially extends the support time from 0.12 seconds to 0.14 seconds rather than reducing the stride frequency, thereby maintaining the overall rhythm.

Then comes the last twenty meters.

The final sprint begins.

Once they arrived at this place, Chen Juan began to gain the upper hand.

Frazier gradually shifted to a defensive stance.

Faced with decreased muscle excitability due to lactic acid buildup, Chen Juan immediately adopted a strategy of "adjusting the priority of synergistic muscle group recruitment":
In other words, when the contraction force of the quadriceps decreases, the activation intensity of the gluteus maximus and hamstrings automatically increases, and then generates additional propulsive force through hip extension.

The calf muscles employ a "rapid contraction" technique, bursting into high-intensity contraction at the initial stage of pushing off the ground, and then utilizing the elastic potential energy of the tendons to complete the remaining push-off process, reducing the energy consumption of active contraction.

Control fatigue.

then.

Fine-tune the center of gravity.

During this phase, Chen Juan slightly adjusted the forward tilt angle of her torso from 30° to 28°, an adjustment based on both aerodynamic and mechanical balance considerations.

she was.

I've lived on Ersha Island for so many years.

I've been by Su Shen's side for so many years.

They had already been exposed to it from a young age.

Everything must be based on scientific evidence.

The future belongs to sports science.

This passage has become something akin to an imprint on one's mind.

It was deeply etched into Chen Juan's mind.

Micro-adjustment technology for the center of gravity trajectory!
Reduce resistance.

According to fluid dynamics calculations, a 28° forward tilt reduces the frontal area by 3% compared to a 30° tilt.

The air drag coefficient is reduced by 0.02, which can save 0.015 seconds/20 meters at a speed of 9 m/s.

With reduced resistance, the stability of the center of gravity can be increased.

On Ersha Island, real-time monitoring was conducted using plantar pressure sensors, and the center of gravity was controlled to be 22±1.5 cm in front of the ball of the foot.

This ensures that the horizontal component of the push-off force remains above 78%.

This is to avoid increased impact upon landing due to excessive forward leaning.

Stabilize your body's center of gravity.

Therefore, it may appear to you that only the athlete's performance is improving.

My abilities are improving.

But how exactly did they improve?
It's definitely not about opening the panel and adding a dot.

Rather, it is supported by complex scientific theories and scientific systems.

This is the soul of all the athletes on Ersha Island now.

of course.

We've only just entered the sprint zone.

Chen Juan looked ahead.

Only Frazier.

If I continue to accelerate at this point, I can certainly continue to narrow the gap, but...

This isn't the final.

The advantage we have over those behind us is already significant enough.

therefore.

Seeing that she had secured the top two positions, Chen Juan began to ease up.

All we need to do is keep Ahorei behind us.

Now she is a seasoned Asian superstar.

I won't be so impulsive and reckless anymore.

……

"Chen Juan is keeping up with the momentum, very good, she should be able to catch up a bit more, huh? Chen Juan, Chen Juan has let go."

"Fraser crossed the finish line in second place."

"Letting go was the right thing to do."

"Securing a top-two finish is enough. Frey is too strong; there's no need to waste energy here, especially since the final is in two hours."

"Although I believe Chen Juan already possesses two high-level abilities, we should minimize consumption whenever possible."

"Her goal this time is still to win a medal."

"There's no need to waste energy here in order to achieve this goal."

Li Tao's words make a lot of sense.

After all, the final results are only based on the finals, not the semi-finals.

They didn't even watch the medal presentation for the semi-finals.

So just sticking to advancing is enough.

The most crucial point is that he also knows what Chen Juan's mission is this time—to win a medal at the Olympics.

Now everyone certainly hopes he can win another medal.

That would allow him to have both a World Championship medal and an Olympic medal.

This has solidified our unshakeable position in the women's 100-meter dash in Asia.

That's definitely what the higher-ups hope for too.

It means that the person above and below includes herself.

Everyone hopes to win a medal at this World Championships.

Surrounded like this.

There's really no need to waste too much energy in the semifinals.

Chen Juan actually felt great and really wanted to keep running, but reason made her stop.

I stepped on the brakes.

Because he was definitely aiming to win the bronze medal in the finals.

The team had all the right conditions to win the bronze medal at the last Olympics.

Only she could do that.

Otherwise, it would be really difficult.

This time, in order to be in better form and aim for the bronze medal, we need to reduce the chances of anything happening by chance.

The semifinals are needed; take some time to lighten your load.

Frazier ultimately came in first in her group. She was probably being chased quite hard by Chen Juan here, and for a moment she forgot to step on the gas. She managed to get a time under 10.90 seconds.

10 seconds 87.

To achieve this result in the semifinals is truly unbelievable.

And last year was the Olympics.

Frazier's battery life.

This is truly a rare occurrence in history.

Chen Juan was second; this shot was 10.93.

The results were very good.

It pinned down Ahore behind him.

10.95.

Big Q advances.

Even Chen Juan could only advance second.

The young girls who previously swept through adults in Asia.
