The Su God of the Reopening of the Sports Arena

Chapter 2289 Young people should be bolder.

Xie Wenjun is training this winter.

They weren't idle.

These real-world competitions have been laying the foundation for his technical advancement.

However, he has not yet fully mastered these techniques.

Or perhaps you've mastered it, but don't yet have enough experience to apply it in a match.

He originally planned to find some competitions after the major tournament ended and then slowly hone his skills.

Try it little by little.

Sun Haiping initially agreed with his idea.

However, plans can never keep up with changes.

Just like that.

With the withdrawal of several favorites to win the championship.

The medal positions have been significantly reduced.

In addition, Xie Wenjun's own condition was unexpectedly good to Sun Haiping.

He's also very young.

They've made it to the finals of major competitions before.

So, looking at it this way...

Anyway, there's still a future.

The opportunity is right in front of us.

Just take a gamble.

perhaps.

Just as Sun Haiping herself told Xie Wenjun.

This might be the best chance you've ever had to win a card.

Perhaps even if our strength improves in the future.

There won't be such a good opportunity to win a medal again.

For athletes, achieving results in major competitions is crucial.

Is the key.

That's what the higher-ups and leaders want.

Only in this way can we truly guarantee the athletes' future path.

These.

Sun Haiping knew better than anyone else.

So after thinking about it for a while, he made his own judgment.

A bold judgment.

He told Xie Wenjun before the match—

Be a little bolder later.

This technology is used to compete for medals.

Xie Wenjun was taken aback.

To be honest.

What techniques can be used to compete for medals?

He originally wanted to ask a question.

But when I saw Sun Haiping's face and his eyes...

Xie Wenjun understood immediately.

Master, this is to let me...

Unleash your ultimate move in the final round of the competition.

"But Master, I don't feel ready yet. I haven't accumulated enough experience in the competition. Are we just going to jump straight into this? You know our previous plan..."

Xie Wenjun hadn't finished speaking yet.

Sun Haiping interrupted:
"I know it's different from the previous plan, but plans can never keep up with changes."

"You know what? I really like a quote from President Su, whom you admire."

Sun Haiping looked at his disciple and knew that this was a completely different athlete from Liu Xiang. Liu Xiang didn't need him to say these things.

But how many people are like Liu Xiang?

If everyone follows this standard, then I won't need to coach anymore after Liu Xiang retires.

Because you might never meet someone like that in your entire life.

and so.

Sun Haiping demonstrated his patience here.

He guided her step by step:
"Nothing is ever fully prepared."

"We must be prepared for situations where we are never truly prepared."

"The opportunity has come."

"Don't miss it."

"Because there's never a time when you're fully prepared."

……

Xie Wenjun was shocked by these words at the time.

In his previous impression, Sun Haiping was a rather calm and composed person who rarely had such bold ideas.

Otherwise, Liu Xiang himself would have wanted to change the number from eight to seven back then.

Sun Haiping wouldn't directly stand up and oppose it.

can.

What did he just hear his master say?
Let him...

Be bold.

This.

Am I sure I didn't mishear?
Actually it is not.

Sun Haiping, all these years, let's not talk about anything else.

Seizing opportunities.

I do have some insights to share.

Moreover, none of the athletes under his tutelage had a bad word to say about him.

This definitely speaks volumes.

Then.

In terms of considering the athlete's career.

Sun Haiping was absolutely dedicated.

Liu Xiang may lack experience in those areas, but judging from Liu Xiang's attitude towards him, even giving him a villa, you can tell whether he cares about Liu Xiang or not.

If this was Xie Wenjun's best chance to win a card in her life?
Then.

Sun Haiping will definitely let him catch her and fight hard.

So before the start.

Xie Wenjun's starting block setup broke with convention.

The front starting blocks are 1.18 meters from the starting line, and the rear starting blocks are 1.45 meters from the front starting blocks, forming a 7° angle with the center line of the track.

This design stems from his height of 1.90 meters and lower body length of 102 cm.

Compared to European and American athletes, Asian athletes have relatively shorter lower limbs, but greater hip joint flexibility.

The closer starting block spacing compared to European and American athletes is 3-5cm shorter on average, allowing him to utilize lower limb explosive power more efficiently when pushing off the ground.

The 7° angle cleverly guides the body to generate an inward force at the moment of initiation.

This helps it quickly cut into the inside of the runway.

Reduce the length of the path through the bar.

Sun Haiping would have found it hard to understand why a starting ram setup required so many intricacies.

But now he understood.

All these years spent on Ersha Island haven't been for nothing.

He also spent a lot of time having discussions with Ralph Mann about his experiences.

So people might not be interested in him.

But as long as he's interested in people, that's enough.

He is now in a position where he wants to learn.

Then we should naturally adopt the corresponding attitude.

Sun Haiping did a very good job in this regard.

And he has indeed learned a lot of new things over the years.

Things I had no idea about before.

Just like right now.

This is done based on sports biomechanics analysis.

Instead of just making things up out of thin air.

This configuration increases the proportion of his horizontal force when pushing off the ground to 78%, exceeding the previous 72%.

Meanwhile, the vertical component force is controlled at 22%.

This ensures both a fast start-up speed and avoids excessive fluctuations in the center of gravity caused by excessive vertical force.

In addition, the starting block pedal angle was adjusted to 15° for the front plate and 25° for the rear plate. This asymmetrical design suits Xie Wenjun's habit of using the balls of his feet to generate force, which improves the efficiency of muscle recruitment at the moment of push-off by 12%.

At the same time, Xie Wenjun positioned the starting blocks at a 7° angle to the center line of the track. This seemingly minor angle adjustment actually contains a sophisticated principle.

This is because when pushing off the ground, the lateral force generated at this angle can guide the body to naturally tilt inward.

This helps him quickly enter the track after the start.

Shorten the actual path length for crossing the barrier.

The reason why Xie Wenjun's body always shifts when he starts is that this actually helps him get back to a normal starting position.

Calculations show that this design can reduce his total hurdle clearance path by about 8-10 centimeters, an advantage that cannot be ignored in races where every second counts.

During the preparatory stance phase, Xie Wenjun's body posture demonstrated a high degree of professionalism.

His hands were slightly wider than shoulder-width apart, with his fingers gripping the track. This grip provided more stable support and helped to better transfer the swinging force of his arms to his whole body at the moment of takeoff.

Keep your head hanging down naturally.

Keep your eyes on a fixed point about 50 centimeters in front of the starting line.

The angle of your gaze can ensure the stability of your body's center of gravity.

It can also react quickly when the starting gun fires.

The hips are positioned slightly higher than the shoulders.

It forms an angle of approximately 135° with the ground.

This posture allows the hip, knee, and ankle joints to be in a moderately flexed state, stretching the main power-generating muscle groups such as the quadriceps and hamstrings to an appropriate length.

Based on the muscle length-tension relationship, the muscle is able to generate greater force when it contracts.

At the same time, keep your back straight and your core muscles engaged to provide a stable power transmission foundation for the upcoming starting movement.

This preparatory stance is designed to allow him to quickly activate his entire body's power at the start of the race, while maintaining balance and coordination. Indeed, that's true science—every step is designed.

Unlike before, we won't make judgments based solely on our eyes and experience.

Everything must be traceable and based on reason.

0.141 seconds after the starting gun fired, Xie Wenjun was launched into the air.

The first two steps are 1.22 meters and 1.30 meters long, respectively, with a push-off time of only 0.23 seconds per step and a step frequency as high as 5.1 steps per second.

This high-frequency, small-step start utilizes the rapid contraction characteristics of fast-twitch muscle fibers to lift the body's center of gravity from a squatting position in a very short time, while simultaneously swinging the arms at a high frequency.

The swing amplitude reaches 85% of the shoulder joint's range of motion.

Maintain trunk stability.

It is worth noting that here—the trajectory of his arm swing presents a unique "figure-eight" shape.

When swinging the left arm forward, the elbow joint should be brought inward to the left side of the chest.

Swing your right arm back to the right rear of your hip.

This cross-swinging motion effectively counteracts the rotational torque generated by the lower limbs pushing off the ground, keeping the body's center of gravity offset within ±2cm.

Starting from the third step, Xie Wenjun entered the "step-by-step acceleration" stage.

He gradually increased his stride length by 0.12 meters, smoothly raising his stride frequency from 5.1 steps/second to 5.4 steps/second.

It forms a unique acceleration curve.

The core of this acceleration mode lies in "energy gradient release"—by precisely controlling the force and time of each step, the body's kinetic energy increases linearly, avoiding energy loss caused by instantaneous bursts.

In terms of increasing stride length, this is achieved by gradually increasing the extension range of the hip and knee joints, as well as extending the push-off time.

During each push-off, the lower limb muscles undergo full contraction and extension, effectively converting the ground reaction force into forward propulsion.

At the same time, pay attention to the landing method of each step.

By landing on the forefoot first and then quickly transitioning to the entire foot, the impact force upon landing is reduced, and the push-off action is completed quickly, improving energy utilization efficiency.

In terms of improving stride frequency, Xie Wenjun achieves this by strengthening the nerve's control over the muscles and increasing the speed of muscle contraction and relaxation.

His nervous system can precisely regulate the rhythm of muscle work, enabling his legs to complete more swinging and pushing movements in a short period of time.

During acceleration, his center of gravity remained about 20-25 centimeters in front of him, forming a stable forward trajectory.

Such center of gravity control helps maintain body balance and allows the force of each step to be better converted into forward acceleration.

Through this dynamic optimization of step length and frequency, Xie Wenjun is able to achieve efficient energy utilization and speed improvement during the acceleration phase, laying a solid foundation for successfully completing the eight-step hurdle.

Continuous strides.

In the fifth step, he demonstrated key technical details: the knee of the supporting leg was kept at a 140° bend angle, and the ankle was dorsiflexed to 30°, forming an "elastic bow" posture.

This posture puts the calf muscles and quadriceps femoris in an optimal state of tension. According to Hooke's Law, the degree of muscle pre-stretching is directly proportional to the subsequent contractile force.

During the sixth step, he can instantly generate a pushing force of 3.6 times his body weight, which is 8% higher than the conventional posture.

The swinging leg simultaneously completes the "folding-forward swing" preparatory movement, and the knee joint angle suddenly shrinks from 135° to 90°, storing kinetic energy for the take-off.

At this point, he had not yet fully distinguished himself.

This is because startup has never been a particularly strong point.

Unless you are Liu Xiang.

otherwise.

Sun Haiping's overall training approach focuses on acceleration in the mid-to-late game.

That's why it's so fast.

This is already the result of continuous improvement in physical fitness and changes in technique during winter training.

In the past...

It's not just a matter of insufficient technical detail.

Physical capabilities.

That's not enough to go around playing like that.

Again.

Even the best details require physical movement to achieve.

There is no physical body as a vessel.

It's no use saying anything.

The greatest truth of Ersha Island.

This is it.

Therefore, you can see athletes coming from Ersha Island.

There is no athlete whose physique will not far surpass that of domestic athletes, or even athletes from all over Asia.

To engage in competitive sports.

You have no physique.

Your physique is not strong enough.

I also want to get a good ranking.

That's simply wishful thinking.

The second-to-last step is the core control point of Xie Wenjun's technical system.

He precisely controlled his stride length to 1.68 meters, 0.07 meters shorter than the sixth step, while lowering his center of gravity by 10 centimeters, putting his body into a "diving and gathering momentum" state.

Sun Haiping's words still echoed in my mind:
This operation is based on the principle of motion trajectory correction: by actively shortening the stride, the body's center of gravity is shifted back by 12cm, leaving an error tolerance space of ±5cm for the start of the last step.

When pushing off the ground, his supporting leg is adjusted to a 42° angle with the ground to maximize the horizontal force.

The ankle dorsiflexion angle increases to 35°, activating the elastic potential energy of the Achilles tendon.

At the same time, the swing leg initiates a "spiral forward swing" in advance—first swishing 20° outward from the body.

Then quickly pull inwards, pointing straight at the top of the railing.

This composite trajectory effectively corrects the lateral shift that his own body might have caused due to the eight-step hurdles.

Keep your center of gravity on the center line of the track at all times.

This is in contrast to the past when he was simply kept in the midline of his body.

However, there are no specific methods or operation manuals to refer to.

They're not even on the same level.

This is what truly tells athletes what they should do.

Instead of leaving the athletes themselves confused.

Then we arrived near the first column.

We've arrived at the starting point.

At the moment of takeoff, Xie Wenjun's technical precision reached its peak.

He knew that no matter how well he had done before, the key was to take the first step.

If the start and step are not done well.

It's pointless to say anything.

Ultimately, this project is still called hurdles.

Therefore, the success or failure of hurdling.

Is the most important thing.

Xie Wenjun focused her mind.

His right leg, which was the starting leg, extended with an angular velocity of 305°/second.

Extend the hip joint to 160°.

Let him achieve the ideal starting distance of 2.08 meters.

However, this is just the beginning of the eight-step improvement plan for the top bar; we still need to work on the rest.

The strategy employed here is the same one he used before – the "low-level clearance" approach:
In other words, when the swinging leg clears the hurdle, the vertical distance between the lower leg and the hurdle is only 8cm, which is much smaller than the usual 12-15cm. This posture greatly reduces air resistance.

The drag coefficient decreased from 0.8 to 0.72.

To achieve a low hurdle clearance, he coordinated his torso leaning forward at 45° and his swing leg pressing down in mid-air to control his body's center of gravity at a height of 15cm above the top of the hurdle.

At the same time, the take-off leg extends and then quickly folds back, completing the "extension-folding" action within 0.08 seconds, reducing the time spent in the air.

In terms of aerial attitude control, Xie Wenjun maintained a forward tilt angle of 45°, kept her head and torso in a straight line, and kept her eyes on the railing in front of her.

His body formed a tight and smooth arc in the air, minimizing air resistance.

Passing over the railing.

After his swinging leg clears the hurdle, he immediately initiates the "lower leg retraction" action, quickly retracting his lower leg within 0.1 seconds to prepare for the subsequent run after landing.

This highly efficient take-off and mid-air attitude control technology significantly reduces his hurdle clearing time!
And it can quickly recover its speed after passing through a hurdle!

It is precisely because of this completely different eight-step approach to the top of the bar.

He rushed to the front after passing here.

After clearing the hurdle, Xie Wenjun's landing technique is key to maintaining speed.

Just as his swinging leg was about to land, his lower leg extended forward, and he landed on the ground heel first.

The knee joint bends rapidly to 130° the moment of landing.

This creates a good buffer.

To reduce the impact of landing on the body.

At the same time, his starting leg swings forward quickly, preparing to take the first step in the next hurdle run.

The first step after landing.

He controlled his stride length to 1.9 meters.

This step is accomplished through a quick and powerful push-off motion.

The push-off time is only 0.23 seconds.

During the process of pushing off the ground.

His ankle, knee, and hip joints extended rapidly in sequence, quickly converting the vertical force upon landing into a horizontal forward momentum.

His arms also swung actively during this process, coordinating with his lower limb movements to accelerate his forward stride.

This is an attempt to utilize this highly efficient implementation and connection technology.

Xie Wenjun is able to retain as much speed as possible when clearing hurdles and quickly get into the rhythm of running between the next hurdle.

Don’t say anything else.

Perhaps he himself never even thought about it.

After he gets there.

He has already fallen...

In second place.

Second only to the best runner ahead.

American bull.

David Oliver.

Sun Haiping is here.

He crossed his arms, somewhat inexplicably excited.

The fingers are twitching.

She gently clasped her arms.

That's right, that's exactly it.

young people.

You have to be a little bolder.
