The Su God of the Reopening of the Sports Arena

Chapter 2288 Why is there still a yellow figure in front?

Xie Wenjun hadn't expected this either.

To his surprise, David Oliver was sitting right next to him.

On one side is Ryan Wilson.

seriously.

This is a truly magical feeling.

Of course, this doesn't mean that this combination has never appeared before.

Prior to this, such pairings were almost a common sight in international competitions.

He saw it himself often.

Just this person.

It wasn't him.

Just now?

It was him who took his place.

……

"Alright, now all the athletes are in their lanes. Our athlete Xie Wenjun is in lane 5. This feeling makes me feel a little dazed for a moment."

Li Tao shared the same sentiment as Yang Jian.

I really didn't expect it.

Liu Xiang has retired.

Then we can have our own people standing in the middle of this lane.

Just seeing this scene.

Countless people probably think it was worth it.

Even if you didn't run well.

We couldn't win the gold medal.

The scene alone was enough to make them stop and watch.

There was nothing we could do; before this, we were aiming for the gold medal in this project.

I can feel this way now.

That's already a low standard.

That's too low a requirement.

"Everyone, hold your breath and enjoy the next 13 seconds."

Yang Jian finished speaking.

The electronic password has been activated.

On your marks.

The athletes are all getting ready at the starting line.

set.

Liu Xiang was also at home.

They stopped walking.

Stop and watch the game.

Even after retirement.

His mindset.

They still care about this sport.

"A good start is very important. Let's see how Xie Wenjun handles it."

BOOM ...

A gunshot rang out.

Game start.

No one jumped the gun this time.

Humans are indeed highly adaptable, especially compared to Daegu in 2011 when zero tolerance had just been implemented.

At that time, most reactions would be slow and hesitant.

This is only the end of one major competition cycle.

Most people have adapted to it.

William Sharman, running in lane one, knew his strength lay in the final sprint, so he adopted a strategy of prioritizing stability and conserving energy at the start.

His starting block footplate was set a little further from the starting line.

The front starting blocks are about three-quarters of a foot away from the starting line.

The rear starting blocks are about one foot and a quarter of a foot away from the front starting blocks.

This setup allows him to exert more force by pushing off the ground when starting.

After the gunshot, Sharman's reaction time was 0.148 seconds. In the initial phase, he used a relatively conservative acceleration rhythm for his first four steps, with stride lengths of 1.2 meters, 1.3 meters, 1.35 meters, and 1.4 meters, respectively, and a stable frequency of 4.5 steps per second.

He did not pursue the extreme explosive acceleration like Richardson, but focused on maintaining a smooth transition of his body's center of gravity to avoid imbalance caused by excessive acceleration.

As he moved toward the first hurdle, Sharman fine-tuned his rhythm by making small adjustments to the amplitude and frequency of his arm swings.

The left arm swings slightly below shoulder height, while the right arm swings back to the back of the waist.

This arm-swing technique helps maintain body balance while conserving power for subsequent acceleration.

When he reached the seventh step, he consciously began to shift his center of gravity forward to prepare for the eighth step.

Arriving at the railing.

His stride extension during the take-off is relatively stable.

The angular velocity of the push-off is approximately 290°/second.

The swing leg should be swung forward at a moderate angle.

While ensuring a smooth hurdle clear, conserve energy for acceleration in the later stages.

Of course, he did this in order to achieve the best possible results.

You can't just run as fast as you want.

After all, his fastest time in his career was 13.26 seconds.

Try to maintain your performance as consistently as possible.

Will suffice.

I want to rush forward.

He himself knew it was unlikely.

He just wanted to leave a good impression here.

Therefore, he chose this running style.

In terms of individual tactics and the final result, you can't say he was wrong.

Because if you act recklessly, it will be disastrous in the 110-meter hurdles, a race that demands perfect rhythm.

They will only die a more miserable death.

Next to him is Jamaican athlete Andrew Riley.

That makes their desires seem much more positive.

This year's time was 13.14 seconds in windless conditions.

It is his greatest confidence.

And Merritt was out of the game.

His teammate, Hansler Pagement, was also gone.

That's how he sees it.

You will have your own opportunity.

This is the change in mentality that occurs when some pre-tournament favorites suddenly lose their eligibility to compete.

Simply put—

He thought he was capable.

This is a great opportunity for me to win a medal.

Don't say it yet.

At the beginning.

Andrew Riley demonstrated the explosiveness and agility characteristic of Caribbean athletes.

Although technically it also involves eight steps.

But relying on its powerful burst of speed, it quickly broke through.

The individual's reaction is the most important factor.

The time is 0.135.

He used a seven-step approach to the hurdle, with the first three steps after the start being 1.3 meters, 1.45 meters, and 1.6 meters long respectively, and a frequency of up to 4.9 steps per second, demonstrating a powerful starting explosive force.

Unlike other athletes, he deliberately shifted his center of gravity 5 centimeters to the left before taking the stride.

This "side-tilt" hurdle technique is his signature move.

It is said that it can effectively utilize the body's rotational inertia.

This allows the swing leg to clear the hurdle more quickly.

but.

Everything has its advantages and disadvantages.

How could you possibly have gotten all the benefits?

There are some unique aspects to doing this.

So what are the drawbacks?

Or what would be the cost?

Of course there are.

That is.

As Riley's swing leg cleared the hurdle, his ankle exhibited an unusually high dorsiflexion angle.

This flexibility allows his lower legs to glide almost parallel to the hurdle, reducing resistance when clearing it.

However, this radical technology also comes with risks.

If the step point deviates.

This can easily lead to accidents involving the barrier.

He handled the first hurdle quite well, of course.

No big deal.

Since there are no problems, the returns are also quite good.

As the host country's athlete, Shubenkov adopted a steady and progressive eight-step approach to the hurdle in lane seven.

It can be seen that his starting blocks are slightly wider than Xie Wenjun's.

The aim is to enhance lateral stability.

After the gunshot, he started with a reaction time of 0.154 seconds, using a uniform acceleration mode for the first four steps.

The stride length gradually increases from 1.25 meters to 1.55 meters.

The frequency was maintained at 4.6 steps per second.

This conservative yet stable approach to starting up helps reduce the probability of errors.

Moreover, he no longer runs in a style that relies on gaining a significant advantage from the start.

As long as we seek progress while maintaining stability, that's fine.

He never reached his peak.

Some of those signature peak moves are still beyond my current ability to perform.

In the final three steps before the first column, Shubenkov demonstrated strong rhythm control.

Although he hadn't reached his peak, Shubenkov still displayed many different qualities.

For example, he fine-tuned his step frequency.

The speed was increased from 4.6 steps/second to 4.8 steps/second.

relatively.

The step length ratios were changed to 1.6 meters, 1.65 meters, and 1.7 meters.

Make sure to step onto the starting point with your right foot.

The first column is the attack column.

At the start of the stride, his center of gravity was 5 centimeters higher than that of Jamaica's Riley.

This higher center of gravity position sacrifices some hurdle-clearing speed.

However, it can also effectively reduce the risk of hitting the barrier.

This reflects his competition strategy of "prioritizing stability before speed".

It's definitely a home-field advantage.

Then suddenly Merritt and Pagement were also killed.

These two players are stronger and more famous than him.

That's how he sees it.

Isn't this also an opportunity for oneself?

On the arena.

A bold person.

There is never a shortage of them.

Shubenkov's restless heart was instantly swayed.

My whole being was mobilized.

Next to Xie Wenjun is Oliver.

His response this time was mediocre, at only 0.147.

But this is enough for him.

At his peak, Oliver was a pure physical powerhouse.

Otherwise, Liu Xiang's track and field fans wouldn't have jokingly called Oliver "Muscle Stick".

On the one hand, it's saying his technique isn't good enough, but on the other hand, it's also a tacit admission that his physical attributes are indeed strong.

That's pretty abnormal for a hurdler.

However, adjustments have been made in recent years due to a downturn, physical condition, and age.

To put it jokingly, out of 10 columns, 8 would be knocked down.

So now he will knock down fewer and fewer hurdles.

David Oliver, in lane four, stood in front of the starting blocks. The American hurdling legend, who was over thirty years old, placed his hands on the track, his calloused palms pressed tightly against the plastic surface.

He has participated in many competitions, but each time he has failed to perform well for various reasons.

Various anxieties and poor performance in major competitions were used to describe him.

But now, his main rivals are gone.

The few people who could threaten me this time all failed to make it to the finals for various reasons.

David Oliver.

I probably felt it myself.

That might be it.

This is the best opportunity of my career.

This is the last chance to become a world champion.

This might be the only chance.

after all.

He is getting older.

His personal abilities are declining, a fact he can clearly sense himself.

Therefore, he must seize the last window of opportunity to win the championship.

Otherwise, he might be the only person in history to break the 12.90-second barrier but never win a major competition gold medal.

Oliver had heard this argument for far too many years.

He wants to make a change in this game.

As a veteran who has competed in the field for more than ten years, Oliver may have been young and impetuous in the past, but now that he is older, he has come to understand that in the 110-meter hurdles, the start is not just a contest of speed.

It is also the ultimate test of technical details and accumulated experience.

Faced with the aggressive strategies of young players who pursue extreme explosive power, he instead became a composed veteran.

Oliver's starting block setup broke with convention, with the front starting block positioned 1.45 meters from the starting line.

The rear starting blocks are 1.2 meters away from the front starting blocks.

This asymmetrical layout stems from his in-depth analysis of his own limb length and force exertion habits.

According to the principles of sports biomechanics, a more forward starting block allows him to obtain a greater horizontal component of force during push-off, while the relatively compact spacing of the rear starting blocks facilitates a quick shift of his center of gravity at the moment of launch.

He deliberately positioned the starting blocks at a 3° angle to the center line of the track.

This tiny angle adjustment guides the body to naturally tilt inward when pushing off the ground, reducing speed loss caused by lateral displacement.

Oliver is becoming increasingly scientific.

Compared to the old Oliver the Bull.

Now it's more like an experienced and wise old ox.

At the moment the starting gun fired, Oliver's reaction time of 0.147 seconds was not outstanding among all the competitors, but his starting strategy was full of hidden tricks.

In the first two steps, he used a "delayed acceleration" tactic, controlling his stride length to 1.25 meters and 1.3 meters respectively, significantly shorter than his youthful explosive start.

This seemingly conservative choice is actually based on a deep understanding of the characteristics of muscle contraction—by extending the time of pushing off the ground in the first two steps.

It reached 0.28 seconds, which is 0.03 seconds longer than when I was younger.

This allows him to activate more slow-twitch muscle fibers.

While ensuring stability during startup, it is important to avoid premature fatigue of fast-twitch muscle fibers.

The reason he did this was because he had reached the limit of his own age.

We can no longer start things up as recklessly as before.

He no longer has the ability to drive 12.90 seconds as he did at his peak.

In fact, he can't even open a 13-second timer now.

Fortunately, those super masters are no longer around.

So it won't take 13 seconds to start.

There must be a way to run a race that takes less than 13 seconds.

Oliver is starting to use his brain now.

Even Liu Xiang thought so.

Somewhat magical.

Looks like he's old.

It really can catalyze changes in a lot of people.

The start-up swing arm has also been adjusted.

The first two steps involve swinging the arms at only 70% of the normal range, with the left arm swinging forward to chest level and the right arm swinging backward no more than hip level. This restrained arm swing effectively reduces the rotational inertia of the torso, allowing the body's center of gravity to shift forward smoothly.

Starting from the third step, Oliver enters a phase of gradual acceleration.

He steadily increased his stride length by 0.15 meters, gradually raising his stride frequency from 4.2 steps per second to 4.8 steps per second.

This linear acceleration mode keeps his center of gravity on an ideal parabolic trajectory.

Post-race 3D data analysis showed that during acceleration, his center of gravity projection remained within the golden zone of 20-25 centimeters in front of his body for each step.

This figure is 12% higher than the average level of the players in the same group.

It's also more than 5% higher than what I achieved back then.

It's a pity that his explosiveness has diminished.

otherwise.

That's all there is to it.

That's enough to make him stronger.

Fortunately, he has now made technological changes to compensate for the decline in his physical fitness through technological enhancements.

In step five.

Oliver showcased unique technical details:
He deliberately kept the knee bend angle of his supporting leg at 145°.

It forms a "flexible and energy-saving" posture.

This angle is somewhere between straight and curved.

It can be achieved without sacrificing speed.

This will provide a reserve of potential energy for future takeoffs and landings.

At that time, he was not yet in first place.

This would have been almost impossible for him in the past.

But now he is able to control his temper.

We will provide support step by step.

And he is now.

But it takes seven steps to get up to the railing.

Liu Xiang looked at it.

The sixth step is the essence of Oliver's seven-step hurdle technique.

He shortened his stride to 1.55 meters, 0.1 meters less than the previous step.

This "braking adjustment" contains profound kinematic principles:

By actively shortening his stride, he was able to quickly shift his center of gravity backward by 15 centimeters.

This allows for greater flexibility in the final step of the stride.

According to statistics from the IAAF, athletes using this technique have a 37% lower starting point error rate than conventional athletes.

Based on past experience...

Oliver's error rate is among the lowest of all top players.

The highest one is probably.

Now that his physical condition has declined, he has to make trade-offs and adjustments.

We can no longer attack recklessly and without regard for consequences, as we did before.

can be seen.

Oliver's push-off in this step was textbook perfect:

The dorsiflexion angle of the supporting leg's ankle joint reaches 25°.

The explosive contraction of the calf muscles generates a pushing force of 3.8 times the body weight.

At the same time, the swinging leg begins to swing in advance, and the knee flexion angle quickly decreases from 90° to 60°.

It forms a "folded spring" state.

This coordinated preloading of the upper and lower limbs allows his body to accumulate sufficient kinetic energy before taking off.

Then comes the starting stride.

At the moment of takeoff, Oliver's takeoff leg.

moment.

It exhibits amazing explosive power.

With a push-off angular velocity of 310°/second and a hip extension range of 165°, this maximum extension enabled him to achieve an ideal take-off distance of 2.15 meters.

More importantly, his swing leg uses an original "double-track arc-shaped upward swing" technique.

That is, first move the arm 45° outwards.

Corrected the horizontal offset that may occur due to the seven-step upper bar.

Then quickly swing it forward, aiming straight at the top of the railing.

This composite swing trajectory, if analyzed using a three-dimensional motion capture system, can reduce the body's center of gravity shift by 18 millimeters.

This is equivalent to a 22% reduction in the hurdles error rate.

Is Oliver's new signings all technical players this year?
This is Liu Xiang.

It looks a bit unfamiliar.

Is this still Oliver the Bull?
No wonder his performance was so slow to pick up this year.

So it turns out they made technical changes.

It seems.

A guy who only ever wants to use his body.

They've started using their brains too.

Take a step.

Oliver displayed the composure of a veteran in controlling his attitude in the air.

He's much more composed than before.

He was seen leaning forward at an angle of 48°.

This ensures the speed at which the hurdles are cleared.

This also avoids loss of balance upon landing due to excessive forward leaning.

After his swinging leg cleared the hurdle, he immediately activated the "lower leg retraction braking" program.

Within 0.12 seconds, reduce the angle of your lower leg from 160° to 130°.

This precise adjustment of attitude in the air creates optimal conditions for the connecting run after landing.

nice.

He had this skill before.

Even Liu Xiang would probably tremble with fear.

but.

How many people can have both peak physical and technical abilities during their physical prime?

It's so hard.

Just this one wave.

Seven steps to the top of the railing.

It's not obvious at first.

The instant you cross over.

Only then did everyone realize it.

Oliver.

I don't know when it rose to the top spot.

Begin to establish your own leading advantage.

The athlete in lane six is also an American.

Ryan Wilson.

His starting block setup was a compromise, with the front starting block three-quarters of a foot away from the starting line and the rear starting block about one and a half feet away from the front starting block.

After the gunshot, his reaction time was 0.167 seconds, and the initial acceleration phase employed a "wave-like" acceleration:
The first step is 1.25 meters.

The second step suddenly increased the height to 1.5 meters.

The third step saw it fall back to 1.35 meters.

Adjust your body rhythm by changing your stride length.

When transitioning to the hurdle-hitting phase, Wilson faced a crucial decision: should he adopt a seven-step hurdle-hitting speed or temporarily adjust to an eight-step hurdle-hitting speed to ensure stability?

Because he is currently in the process of modifying the eight-step and seven-step processes.

Often, adjustments are made based on one's own state.

Just like now.

His choice was—

In the fifth step, increase the step frequency.

The speed was increased from 4.6 steps/second to 5.0 steps/second.

The original seven-step upper bar was adjusted to an eight-step upper bar.

In the end, the safer eight-step approach was chosen.

This ability to adapt to the situation demonstrated his technical flexibility, but it also resulted in his horizontal speed at the start being 5% lower than planned.

But that was enough for him.

Except for Oliver.

Overpowering the others shouldn't be a problem.

But at this moment.

There was another figure.

He was caught between Oliver and himself.

between.

This.

And the color of this figure.

It almost triggered many unpleasant memories for Wilson.

And that color is it.

yellow.
