The Su God of the Reopening of the Sports Arena
Chapter 2290 History! It's Changed!
Chapter 2290 History! It's Changed!
But they're not pushovers either.
Richardson, Schubenkov, and Wilson all began to exert their efforts.
Xie Wenjun didn't gain much advantage in the beginning.
He also knew that he was at a disadvantage.
At this point, the most important thing is to stay calm and composed.
Don't worry about whether these people are better than you.
Being too focused on it can easily disrupt your rhythm.
Focus on being yourself.
Just fine.
Anyway.
Nobody's optimistic about them in this game, is that right?
He didn't experience the same pressure that Liu Xiang later faced.
After clearing the first hurdle, Xie Wenjun immediately enters the "seamless transition" phase. The core of this process is to efficiently convert the kinetic energy of clearing the hurdle into running power between hurdles.
And adjust the rhythm to prepare for the next column.
Upon landing, his swinging leg landed with a heel-to-toe rolling motion, at a 65° angle to the ground.
This method disperses the impact force along the lower leg bones.
At the same time, the elasticity of the ankle joint is used to cushion the impact, converting the vertical impact force into a forward thrust.
At this moment, the knee joint bends to 130° to form a "shock-absorbing spring," completing the buffering within 0.15 seconds before quickly extending and exerting force.
It is worth noting that his starting leg had already begun its forward swing in the air, forming a "scissor cross" motion with his swinging leg.
This means that every time he takes a hurdle jump...
Their actions have also become more aggressive.
Liu Xiang back then.
It's the golden scissor leg.
Running between three hurdles.
Xie Wenjun adopted the "equal length acceleration" strategy: the stride length of each of the three steps was controlled at 1.95 meters, and the stride frequency was stabilized at 5.2 steps/second.
This seemingly uniform rhythm actually hides a secret – the angle of each step gradually decreases from 50° to 48°.
By fine-tuning the direction of pushing off the ground.
The vertical force is gradually converted into the horizontal force, thus achieving a smooth increase in speed.
In addition, his torso lean angle gradually increased from 45° when clearing the hurdle to 48°.
This reduces air resistance and builds up forward momentum for the next hurdle.
The third column.
Xie Wenjun precisely controls the starting point of the stride through "step length fine-tuning"—
The second-to-last step is shortened to 1.62 meters.
The last step extends to 2.05 meters.
This combination allows the starting and crossing point error to be controlled within ±2cm.
At the moment of takeoff, his takeoff leg extension angular velocity increased to 315°/second, and his hip joint extension reached 165°.
It generates a pushing force equivalent to 4.0 times the body weight.
This is an increase of 10% compared to the first column.
And that is the change in physical fitness.
His current physical condition.
And one's physical condition on the original timeline.
It's fair to say they're completely different people now.
It wouldn't be an exaggeration to say they crushed it.
Liu Xiang looked at it and nodded silently.
Although he didn't think Xie Wenjun could achieve a medal-level result in this competition, it was always a good thing to improve his ranking.
It can also lay a good foundation for the future.
So, what is Xie Wenjun's current skill level?
He no longer knows.
After retiring, he did indeed leave the Ersha Island base.
The changes of this year.
He could only guess.
So he didn't expect this.
Sun Haiping.
It's surprising that Xie Wenjun would agree to this.
Such a big wave!
but.
The current approach.
All that could be done was for Liu Xiang to look at it carefully.
Not much surprise.
After all, this isn't a plateau, and judging from the situation in Moscow, there's not much wind.
We need to use hard power to solve the problem.
And now look.
Xie Wenjun's raw talent was evident even after losing two of the top contenders for the championship.
That's not enough to win a medal.
Unless something new is served.
Bang bang bang.
Move on to the third column.
It came as it was said.
All the previous preparations were just appetizers.
This is exactly what Sun Haiping wanted Xie Wenjun to do.
It is the application of new technologies.
There was Xie Wenjun.
Its swing leg adopts—
The technology combines "spiral forward swing + mid-air folding and recovery".
The swing leg starts by making a 45° lateral arc.
Correct your body trajectory, then swing forward rapidly, aiming straight for the top of the railing.
Once the lower leg clears the hurdle, the knee joint quickly flexes to 120°.
Bring your lower leg back under your thigh.
This mid-air attitude adjustment reduces the hurdle clearing time to 0.27 seconds!
what?
This is……
At this time, Liu Xiang...
I was finally somewhat moved.
This……
What kind of technical maneuver is this?
How can I do it myself?
I've never seen it before.
It's normal not to have seen it before.
Because this set of techniques currently only exists in theory on the original timeline, it will be 10 years before they are actually used on a large scale.
In this timeline, Sun Haiping was able to engage in theoretical exchanges with a super bigwig like Ralph Mann.
Plus.
Su Shen oversaw the key moments behind the scenes.
To fuel the flames.
Everything happened so naturally.
It's as if Ersha Island would naturally develop new technologies and systems.
after all.
That's Su Shen.
Isn't that what we've always done?
Haven't they been constantly innovating and innovating again in their own field of track and field sprinting?
It boasts what is probably the best sports laboratory in Asia and even the world, and it is also the most well-funded sports laboratory.
In addition, he occasionally gets to interact with Ralph Mann, a super theoretical genius.
And Professor Su, who reopened his studies.
Occasionally, a series of insightful guidance sessions will be held.
Sun Haiping herself is someone who wants to learn and is willing to learn.
That would allow one to grasp this level in advance.
It's not impossible.
It seems to be a realization made solely by Sun Haiping.
But in reality, it relies on a team, and even more so on the two people mentioned above.
just now.
Because Su Shen always comes up with something new.
The entire track and field world is somewhat stunned.
There seems to be some tacit agreement among them.
Ersha Island.
It is the ability to create and innovate.
The so-called "spiral forward swing + mid-air folding and recovery" composite technology significantly shortens the hurdle clearing time by using the three-dimensional spatial movement of the swing leg and the dynamic adjustment of its mid-air posture.
First is the spiral-shaped forward swing.
This is a trajectory optimization mechanism based on three-dimensional space.
It utilizes the mechanical correction principle of lateral arc initiation.
In the initial stage of the spiral forward swing, the swinging leg initiates with a 45° lateral arc. The core function of this movement is to correct the trajectory of the body's center of gravity.
According to the center of mass motion theorem in sports biomechanics, athletes are prone to lateral deviation at the moment of take-off due to uneven force exerted by the lower limbs.
Lateral arcing achieves trajectory correction through the following mechanism.
Just like this column.
Xie Wenjun's swing leg generates reverse angular momentum by swinging it laterally.
This counteracts the lateral rotational torque during the start of the stride.
According to data provided by the SearchGod Lab, this movement can theoretically reduce lateral body displacement by up to 62%.
Under normal circumstances, it is impossible to achieve the maximum theoretical value.
The difference between the actual value and the maximum theoretical value can be quite large.
but.
As long as you can shift your body laterally.
It decreases during hurdles.
That in itself is a form of improvement.
As for how to get close to the theoretical value, that's something that requires practice throughout one's entire career.
Now?
As long as it works, that's enough.
It's enough to just be able to execute it.
As long as it's useful, that's enough!
The fourth column.
After angular momentum compensation, the next step is to pre-adjust the center of gravity.
This means that by swinging outwards towards the hurdles in advance, you force your body's center of gravity to shift inwards.
To create a better angle for vertical ascent when clearing hurdles.
In theory, this technology can optimize the stride angle to the ideal range of 18°-20°.
Next comes the dynamic mechanism of forward acceleration.
In other words, after making a sideways arc, the swinging leg quickly swings forward, pointing straight at the top of the hurdle!
The swing leg uses the hip joint as a fulcrum and generates high-speed swing through the explosive contraction of the rectus femoris and iliopsoas muscles.
During the lower leg extension phase, the ankle joint is dorsiflexed to 35°.
Extending the lever arm length increases the linear velocity at the end of the swing by 15%.
This is actually a way of utilizing the lever principle.
During exercise.
How to utilize leverage at all times.
It's all a subject of study, regardless of which sport system you're in.
Because of the human body.
It inherently possesses various kinds of leverage.
It all depends on how you use it and how you use it.
At this point, we had entered the hurdles section of the race.
In fact, Xie Wenjun's position was still not prominent at this time.
But if you observe carefully, you will find that...
Compared to his previous matches.
Especially in previous international competitions.
The extent of backwardness in this place now.
It needs to be significantly reduced.
Although it wasn't ranked directly at the top.
But they weren't left behind.
They even squeezed right in among this group of people.
It's just because this is the World Championship final.
If it were a regular competition...
at this time.
He is very likely to be the first to take the lead.
"Xie Wenjun needs to keep going; he's still in the crowd."
"Don't let your rhythm be disrupted; you must find a way to break through!"
Liu Xiang looked at it.
They became increasingly interested.
It seems.
You guys have come up with a lot of new things that I didn't know about.
master.
You've gone too far.
It happened during my training session.
They didn't tell me.
I'll call you right away and give you a proper greeting.
But Sun Haiping was truly wronged.
If Sun Haiping really had such a thing, wouldn't he have told Liu Xiang?
That's impossible.
The fifth column.
During the acceleration of the swing leg, the torso leans forward synchronously, forming a "reverse balance system".
According to the law of conservation of momentum, the forward momentum of the lower limbs cancels out the backward momentum of the trunk, thus preventing loss of balance caused by excessive forward leaning of the body.
He still leaped over it in one bound.
But here.
Landing.
It seems to be moving faster.
This immediately put him almost on par with the people in front of him.
The difference is indistinguishable to the naked eye.
The young Eagles' athlete, Sharman, began to be influenced here.
It landed not long after.
They were overtaken.
at this time.
Ahead of Xie Wenjun was Richardson, the player she had just defeated in the semi-finals, who had once broken the 13-second barrier twice.
If it were Richardson, who could drive for 13 seconds continuously for two hours.
Xie Wenjun has no chance of winning no matter what technique she uses now.
That's absolutely true.
Because of absolute strength.
Any conspiracy or trickery is a joke.
But the problem is.
Richardson now.
Is he at his peak...?
He is not.
After the Olympics, it's obvious that you need to give your body a break.
Let him be in his current state this year.
It wasn't as good as I imagined.
His best time this year is only 13.20 seconds.
It was achieved in Lausanne, a small plateau region, with the help of a tailwind of nearly one meter.
That's about the level.
How much of his hard power does he have left?
That is, the level of just opening at 13.30 seconds.
From that perspective, Xie Wenjun is now constantly getting closer to him.
There is also a scientific basis for this.
It didn't happen suddenly.
Richardson's defeat to Xie Wenjun in the semifinals could be attributed to his own carelessness.
But at this point...
It's already the finals.
There can't be anything we can be careless about.
If you can't outrun them again, then you've really given up.
Richardson also unleashed his full potential at this point.
They wanted to stop Xie Wenjun from overtaking them here.
All I can say is that the idea is good.
However, in practice...
Based on his current level this year.
That's probably not easy.
The sixth column.
Bang bang bang.
Just as Richardson was about to continue pressing Xie Wenjun down, the two of them crossed the barrier almost simultaneously.
To be even more precise, one could say...
Richardson still holds a slight advantage here.
But it's similar to the situation just now.
The moment of landing.
Richardson, who was initially in the lead.
Somehow.
It had already been tied.
then.
To achieve a breakthrough.
Similar to the Little Eagle Nation's Sharman.
How did you do it?
Richardson was a little confused.
He was a little confused as to why he had been in the lead but suddenly fell behind.
He didn't quite understand.
He wasn't as fast as the ones ahead of him.
Where exactly did the acceleration come from?
Of course the answer is yes.
It's called aerial folding and recovery.
This is a movement strategy that utilizes energy efficiently under a new technology.
This is based on the biomechanical principle of reducing rotational inertia.
Once the swinging leg clears the hurdle, the knee joint quickly flexes to 120°, bringing the lower leg back under the thigh.
The scientific basis for this action lies in the optimization of rotational inertia.
In other words, lower leg retraction brings the limb mass closer to the body's axis, thereby reducing the overall rotational inertia.
If you do that, the angular velocity will... increase.
According to the law of conservation of angular momentum, as the moment of inertia decreases, the body's rotational angular velocity in the air automatically increases.
Athletes can use this to complete hurdles faster, reducing hurdle clearance time by an average of 0.02-0.03 seconds.
This is not over yet.
This concept will not only shorten the average time for hurdling in the future.
And there is——
The folding and recovery action also stores energy for the subsequent run after landing.
All that could be seen was the instant it landed.
When Xie Wenjun flexes her knee, her quadriceps and hamstrings are stretched to an appropriate length, generating elastic potential energy.
When landing and pushing off, the elastic recoil of these muscles can generate an additional 12%-15% of explosive power.
This is called elastic potential energy storage.
The connecting action process then begins.
After being retrieved, the lower leg is in a forward swing ready position.
This allows Xie Wenjun to immediately begin the first step of the run in the next section the moment she lands.
Reduce the time required for physical adjustment.
According to kinematic analysis by the Sussex Lab, this technology theoretically improves the efficiency of the transition from hurdle clearing to landing by 22%.
This is all a demonstration of the "spiral forward swing + mid-air folding and recovery" composite technology!
This made him...
Here, he overpowered the out-of-form Richardson.
at this time.
Xie Wenjun didn't have time to think about it.
Richardson.
A strongman in America.
He was defeated by himself just like that.
Before the game.
I really hadn't thought of that.
I dare not even think about it.
This is one of Liu Xiang's rivals.
Pb can drive a short crossover in 13 seconds, a true master.
At this moment...
But here, for myself.
It was suppressed!
"Xie Wenjun has surpassed Richardson! He is currently ranked fourth!"
"Have the opportunity!"
"There's a very good chance!"
The wind speed in this race wasn't high; you could feel it at the start, so it was entirely up to the team's strength to get to the top.
Moreover, after the exhaustion from the semi-finals, they still need to make a top-notch shot in the finals.
For Xie Wenjun...
It's also a test.
but.
We've already reached the fourth.
Should we give up now?
Certainly not.
We have to hold on.
otherwise.
Xie Wenjun herself would never forgive herself.
The seventh column!
Hurdle clearance posture control.
During the forward swing phase, the lower leg sweeps parallel to the hurdle, with a vertical distance of about 6-8 cm. Combined with the forward lean of the torso, this reduces the windward area by 18%.
At the same time, the folding and retraction motion prevents the lower legs from lingering in the air.
Reduce wake effect.
This is--
A combination of spiral forward swing and folding retraction.
It can significantly reduce air resistance.
However, this column features Xie Wenjun...
His body tilted slightly.
Sun Haiping was so shocked by what she saw that she almost broke out in a cold sweat.
It's not surprising that this would happen.
Especially this technical move, which he hadn't done many times in actual combat.
The previous matches were either low-intensity warm-up games in China or preliminary rounds.
The intensity was not high to begin with.
If we do it now, various problems are starting to surface because of the increased intensity.
For example, in this column, Xie Wenjun's side arc angle was too large or the timing was inappropriate.
This causes an excessive shift in the body's center of gravity.
This causes the starting point to deviate from the ideal position.
Increase the probability of hitting the barrier.
This data from the Su Shen Lab shows that for every 5° deviation in the arc angle, the risk of hitting the barrier increases by 18%.
Fortunately, Xie Wenjun managed to stabilize her condition, and her health did not suffer any problems.
Of course, it's also because of his physical strength; his core power has undergone a complete transformation compared to the original timeline.
That's why even if he got scratched...
It can also help stabilize the body.
This way, the rhythm won't be lost too much.
Why were European and American athletes, especially those from the United States, still able to achieve good results even when they compared hurdling to kicking hurdles?
It was their superior physical attributes and core strength that allowed them to hang from the hurdles...
It can still maintain a relatively good forward speed.
This is something that others simply cannot learn.
It was impossible for us before.
but.
After so many years, my body has been honed on Ersha Island.
It wasn't just Xie Wenjun.
So many sports.
So many athletes from Ersha Island.
They are already physically no weaker than these European and American athletes, so are they athletes of West African descent?
This is why physical strength is so important.
If the knee flexion speed is insufficient during the folding and recovery phase.
This can lead to a longer time that the lower leg remains in the air.
This not only increases air resistance but may also affect the rhythm of landing.
Sun Haiping quickly made a judgment in her mind.
But now that things have already been done, there's no possibility of stopping.
We can only hope for the last two hurdles.
We can stabilize the situation.
Let's not make the same mistake again.
Because of that last move, the momentum that had been steadily closing in stopped for a moment.
I want to get close to them again.
It will take time.
For every 0.01-second increase in recovery time, the initial launch speed after landing decreases by 0.2 m/s.
This gap.
Xie Wenjun needs to fill in the last two columns as soon as possible.
Fortunately, the athletes trained by Sun Haiping are all strong in the later stages of the game.
So it's still possible.
Liu Xiang realized it at this point as well.
What exactly does Sun Haiping want Xie Wenjun to do?
He marveled at his master's boldness.
While looking at the screen.
self-mumbling.
Shock.
Top three?
The ninth column.
This is the second to last hurdle. The "spiral forward swing + mid-air folding and recovery" technique is closely related to the starting strategy.
Xie Wenjun is an athlete who uses the eight-step hurdle approach.
Therefore, in the penultimate step of the start, you need to deliberately adjust the amount of your center of gravity to shift backward, leaving enough space for the lateral arc during the take-off.
This creates a coherent kinetic chain between the two in terms of mechanical mechanism.
Athletes who start with high-frequency, short strides need to adjust their stride frequency by 0.2-0.3 steps per second before clearing the hurdle to create a more stable rhythmic foundation for the spiral forward swing of their swing leg.
Doing so will increase fatigue.
Finally, how do we combat fatigue?
It is a core course.
Just like Su Shen this year.
A large part of the effort was focused on combating fatigue at the end.
It is precisely because Bolt does this well.
This prompted Su Shen to specifically strengthen this aspect.
Previously, this aspect could only be regulated by feeling, without detailed data.
However, now Ersha Island, due to Su Shen's influence, is not only home to the world's top track and field sports laboratory.
Then.
What's meant to be will naturally come.
According to instrument measurements, when athletes enter a state of fatigue, the regulatory capacity of the central nervous system decreases significantly.
Xie Wenjun cited an example: EEG monitoring showed that after prolonged high-intensity exercise, the power of beta waves in the brain's motor cortex decreased by 18%-22%, resulting in an increase in the delay of neural signal transmission by 0.02-0.03 seconds.
This delay directly affects the timing of the swing leg's arc initiation, increasing the lateral arc angle deviation by an average of 4.2°, which in turn increases the risk of starting point deviation by 31%.
At the muscle level, fatigue-induced ion imbalance and increased extracellular K+ concentration lead to decreased muscle fiber excitability.
Electromyography data showed that Xie Wenjun's maximum contractile force of the quadriceps muscle decreased by 15%-20% under fatigue conditions, resulting in a decrease in the forward swing speed of the swing leg and an average increase in hurdle clearance time of 0.04 seconds.
At the same time, the extended muscle relaxation time also reduced the timeliness of Xie Wenjun's folding and retraction movements.
An increase of 0.015 seconds in the time the lower leg remains in the air significantly increases air resistance.
In order to maintain hurdle clearance efficiency, athletes will spontaneously produce compensatory movements.
Just like right now.
The feeling of fatigue intensified.
Xie Wenjun increased the forward tilt angle of her torso from 45° to 52°.
Use gravitational potential energy to compensate for insufficient lower limb strength.
However, this will increase the impact load upon landing by 18%, significantly increasing the risk of ankle injury.
By slowing down the lateral arc speed, the angular velocity decreases by 12%-15%, allowing more time for action adjustment. However, this sacrifices the continuity of the hurdle clearance, increasing the clearance time by 0.02-0.03 seconds.
The knee flexion angle was reduced from 120° to 135°, which reduced the need for muscle contraction, but the effect of reducing rotational inertia was weakened by 40%, and the efficiency of aerial posture adjustment was greatly reduced.
but.
These were all situations that Sun Haiping had anticipated.
Because I never thought that Xie Wenjun would have a chance to compete for a medal in this competition, especially in Moscow this year.
Therefore, no strong reserves were made in this area at all.
Now, force two shots in.
There must be an impact on physical fitness, and the final fatigue resistance will definitely be very serious.
perhaps.
Isn't that a bit too much of a stretch?
Although the technology itself has some methods to combat fatigue, the problem is that Xie Wenjun was using it for the first time at this time.
Can they really withstand it?
Sun Haiping felt a little regretful.
He entrusted such a heavy burden to a young player like Liu Xiang, who had just retired and was already becoming a senior figure in the team, right at the start of a world championship...
Isn't this a bit like pulling up seedlings to help them grow?
Sun Haiping.
I had some doubts myself.
can.
It turns out.
So many years of training on Ersha Island.
It's not just about physical strength.
Having watched so many athletes grow and make breakthroughs myself.
These are successes achieved despite difficulties.
Or it could be failure in the face of difficulties.
in fact.
They have all strengthened this aspect.
This strengthened Xie Wenjun herself.
Regarding mental attributes.
This refers to spending a long time in a wolf pack.
Even if you are a sheep.
You will ultimately be affected.
What's more.
Xie Wenjun herself was not originally a sheep.
Just before.
Liu Xiang was simply too dazzling.
He made people overlook him.
In fact.
For many years in China.
Without the support of a scientific system.
He carried us through the short span of 10 years.
The technical decline caused by exercise fatigue is essentially a result of a decrease in the coordination of the neuromuscular and mechanical systems.
Specifically, this manifests as follows:
Neural signal delay: Decreased power of brain beta waves leads to delay in command transmission, disrupting the timing of actions, such as delayed arc initiation.
Weakened muscle output: Ion imbalance reduces the contractile force of muscle fibers, weakening the forward swing speed of the swinging leg.
Mechanical parameter deviation: deviations in movement angle and timing can cause loss of center of gravity, increasing air resistance and landing risk.
Therefore, the "spiral forward swing + mid-air folding recovery" technology needs to achieve dynamic parameter reconstruction and efficient energy utilization.
This restores technical stability under fatigue conditions.
The delay in neural signals caused by fatigue can be compensated for by enhanced proprioceptive feedback.
When an athlete deviates from the arc angle, you can use your proprioception to operate.
This can be achieved, for example, through real-time perception and correction—allowing muscle spindles and joint receptors to transmit limb position information back to the spinal cord at a speed of 40-50 m/s.
Triggering the spinal reflex arc.
The delay is only 0.03-0.05 seconds.
Prioritize adjusting the contraction intensity of the gluteus medius and iliopsoas muscles to quickly correct the arc trajectory.
Alternatively, it can rely on proprioceptors for secondary cortical regulation—that is, after the cerebellum receives feedback from the vestibular system and visual feedback, it adjusts the output of commands from the brain's motor cortex through descending pathways.
The motion parameters are calibrated a second time within 0.1-0.15 seconds.
pity.
You can do these things if you ask Su Shen.
If you want to thank Wenjun, just go ahead.
That's asking too much of people.
Fortunately.
The technology combines "spiral forward swing + mid-air folding and recovery".
This point was already there.
First of all.
Optimize neuromuscular delay by using spiral forward swing technique.
When exercise fatigue leads to delayed nerve signal transmission, the spiral forward swing technique can compensate through a pre-programmed neuromuscular program.
The lateral arc-shaped initiation action of this technology has a fault-tolerant adjustment mechanism.
When a delay in neural signals is detected, muscle memory and proprioception can be used to increase the pre-contraction of the gluteus medius and iliopsoas muscles within 0.1 to 0.15 seconds before the stride begins, enabling the swinging leg to swing at a greater angular velocity.
Increased from the usual 280°/second to 300-310°/second.
Initiate lateral arc drawing.
This is because, from the perspective of sports biomechanics, increasing the angular velocity of the arc can shorten the overall arc time, thus offsetting the effects of nerve signal delay.
Not to mention, the lateral arc motion of the spiral forward swing is designed with the center of gravity correction function in mind.
The resulting reverse angular momentum can neutralize the body shift caused by uneven muscle exertion due to fatigue.
When fatigue increases the deviation of the lateral arc angle, athletes can actively increase the arc amplitude from 45° to 48-50°, and use the principle of conservation of angular momentum to bring their center of gravity back to the ideal trajectory.
The risk of starting point deviation will be controlled from an increase of 31% to within 15%.
The ninth column.
Leap over.
Closer.
They resumed the pursuit.
OK!
Sun Haiping couldn't help but slap his thigh upon seeing this.
Because this shows.
Xie Wenjun.
They successfully utilized a composite technology of "spiral forward swing + mid-air folding and recovery" to address the current situation.
To combat physical fatigue.
Bang bang bang.
There was only one railing left.
At this point, fatigue levels are even higher.
Although Xie Wenjun could no longer catch up with Oliver ahead or Wilson closely following Oliver.
But actually, they are far behind the host team.
Shubenkov.
The gap is not that big.
That is, one body length.
The difference in body position.
It can be done entirely through a single column.
Chase after them.
And now.
Xie Wenjun's opportunity.
Only the one in front remains.
He took a breath here.
I'm so tired, what should I do?
At that moment, a sentence suddenly came to Xie Wenjun's mind—
The spiral forward swing and folding retraction enhance muscle power efficiency.
When fatigue leads to a decrease in the contractile force of major muscle groups such as the quadriceps, the spiral forward swing and folding retraction technique can compensate through the synergistic force exertion mechanism of multiple muscle groups.
From an anatomical and mechanical perspective, the contraction of the gluteus maximus and gluteus medius muscles can generate a powerful hip joint extension torque, while the contraction of the hamstrings can assist in knee joint extension. These three muscles work together with the quadriceps femoris to create a combined force.
When quadriceps strength decreases by 20%, the contraction intensity is increased from the usual 60% MVC to 80% MVC by activating the gluteus maximus.
The gluteus medius increased from 55% MVC to 75% MVC.
The hamstrings' MVC increased from 60% to 75%.
This is done step by step.
This can reduce the forward swing speed of the swinging leg by only 8-10%, far lower than the 15-20% decrease when relying solely on the quadriceps.
When fatigued, the efficiency of the aerial folding and recovery maneuver can be maintained by adjusting the timing and amplitude of the folding.
In other words, when muscle fatigue slows down the contraction speed, you can... initiate the knee folding motion 0.01 - 0.02 seconds earlier!
Although the folding angle can be slightly reduced from 120° to 115-120°.
However, by starting earlier, the time the lower leg stays in the air can still be effectively reduced.
Keep the increased air resistance due to fatigue at a low level.
At the same time, the hamstrings and biceps femoris muscles contract synergistically during the folding and retraction.
It can also utilize the elastic potential energy of muscles.
It assists in completing the recycling process.
Reduce reliance on the force of active muscle contraction.
Once you've done all that, you can step over this last bar.
As mentioned earlier, when fatigued, most athletes compensate for insufficient lower limb strength by increasing the angle of their torso forward lean, but this increases the risk of landing.
It's normal to need to compensate when you get tired and fatigued.
But professional athletes always make up for it.
Perhaps two identical compensations.
The effects are completely different.
Even Xie Wenjun was no exception.
The forward tilt of the torso is compensating, and the problem is becoming increasingly severe.
This situation needs to be changed.
Get over the last hurdle.
By utilizing a composite technology of spiral forward swing and aerial folding and recovery, a more reasonable compensation method can be adopted.
even.
A dead horse is treated as a living horse doctor.
Now anyway.
Xie Wenjun had no other options.
The lateral arc phase of the spiral forward swing.
This can be achieved by increasing the force of the arc stroke.
This provides the body with additional forward momentum, reducing reliance on leaning the torso forward.
This is because increasing the force of the arc can generate a greater forward component of force in the swing leg, which is similar to the gravitational component of force generated by leaning the torso forward, but will not increase the impact load upon landing.
Experimental data show that by increasing the force of the arc stroke, the forward component of the swing leg can be increased by 15-20%, which can control the forward tilt angle of the torso to 48-50°.
This provides sufficient forward momentum.
It can also increase the impact load on the ankle joint by only 8-10% upon landing, which is far lower than the 18% of traditional compensation methods.
This is the method he's using now.
Whether it works or not depends on this test.
Take off.
This is almost the same as Shubenkov, who is not far away.
They both jumped at the same time.
Shubenkov initially held a one-body-length advantage.
If he can maintain his lead by clearing the hurdle before he remembers it, then his top three position is guaranteed.
The 110-meter hurdles have never been a strong event for Russia.
But if you can get the cards yourself.
The value it brings is probably greater than that of other traditional gold-winning projects.
It will only get bigger, not smaller.
That's for sure.
That is.
Will others let you achieve this...?
leap.
Unfold.
landing...
I don’t know when.
Shubenkov discovered his surroundings.
It seems there's one more person in the picture.
what happened?
How could someone suddenly appear?
who is it?
This is……
No judgment is needed, because of this skin tone.
It is one of the few in any straight track and field event.
"My God, after landing, we were almost... neck and neck?!"
Indeed, they are neck and neck.
Because it appears to the naked eye.
The two people operate in roughly the same way.
Around the same location.
About the same distance.
Who will emerge victorious?
Who finished third in the men's 110m hurdles at the Moscow World Championships?
Who will win this medal?
Just watch the next 10-meter sprint.
Logically speaking.
Shubenkov might have an advantage in flat running here.
but.
Track and field competitions are not simply about addition and subtraction.
Shubenkov was ahead because he wanted to keep up with American athletes Oliver and Wilson.
Even in order to properly face Richardson, who was running at a similar pace to him.
He was actually running a little too fast at the beginning.
Of course, there's nothing wrong with that, especially when someone else performs better.
You can only follow along as much as possible.
But then...
This means that we are constantly engaged in a rhythm-based confrontation.
I'm either influencing others or being influenced by their rhythm.
Shubenkov felt very bad.
The beginning was fine, but then we got to the flat running phase.
He then realized that he was competing against the two American athletes ahead of him.
In order to avoid being left behind as much as possible.
Too much energy was wasted.
This leads to the operation here.
On the contrary, some things felt difficult to deal with.
Damn!
Shubenkov secretly thought things were going badly.
When he landed and started running, he felt that he didn't have as much energy as he usually does when running flat.
And this Easterner.
but.
He ran with exceptional ferocity.
Even if there is a difference in ability when running on flat ground.
But this place.
Xie Wenjun is even better at combating fatigue.
In addition, his current physical condition is even better than Shubenkov's.
Let him run at a flat pace, even if he's not as good as the former.
But it held on tightly the whole time.
Clench tightly.
Clench tightly.
Clench tightly.
Just keep biting until the very end.
There will be an opportunity.
because.
People from Ersha Island.
everyone.
Press the line.
For athletes all over the world.
Both have the advantage.
Everyone has it.
Su Shen's individual line-pressing plan.
From Lao Zhao to Zhou Bing.
From the 100-meter hurdles to the current 110-meter hurdles.
Xie Wenjun.
Of course, she was also the one being taken care of.
Then.
There's only one thing on his mind right now.
belief.
As long as you can be about the same as Shubenkov before the final touch.
It's possible for me to...
win.
He won his first major competition medal!
105 meters, 106 meters, 107 meters, 108 meters...
At this point, Oliver had already secured the championship.
Wilson, who came in second, couldn't catch up either.
Then.
Actually, it's the third one.
It was a duel between Xie Wenjun and Shuben Kefu.
Ultimately, it's about individual competition medals.
It's still attractive.
at this time.
Shubenkov still relies on his superior flat running ability.
Xie Wenjun was not allowed to overtake directly.
He also needs this bronze medal.
Then.
Let's see who the brave one is in the end.
Who will prevail when they meet on a narrow path?
"Hold on, hold on! Don't let up if you have a chance!!!"
Yang Jian shouted, "Who would have thought that Xie Wenjun, who was someone we thought would just casually make it to the finals and who didn't have much expectation for?"
This time.
I stood there.
On the verge of winning a medal.
This was unexpected.
This has made Yang Jian quite excited.
Li Tao is similar.
He was the one who spoke.
Not as efficient as Yang Jian.
So I simply...
Let’s not talk about it yet.
I crossed the finish line last time; we'll see how it goes later.
Shubenkov.
Finally, he used every ounce of strength he had.
Two people.
They crossed the finish line at almost the same time.
There's not much to say about the number one spot; it's Oliver.
Oliver's teammate Wilson came in second.
And the 3rd...
who is it?
Not only Sun Haiping, but also Yu Weili, Yuan Guoqiang and the others were staring intently at this moment.
I dared not relax for even half a second.
Do we need to compare the thousands place values?
Want it?
After all, it looks like it to the naked eye.
They're indeed neck and neck, it's hard to tell who's better.
can.
Things that cannot be distinguished by the naked eye.
This does not mean it was filmed under a high-speed camera.
It can also hide itself and not be detected.
High-speed camera.
There will be no suspense left.
call--
The third place is 13.23.
WenjunXie.
The instant W appeared.
Sun Haiping clenched his fist and roared.
This victory was so unexpected, so timely, so extraordinary.
Not like Liu Xiang before.
They were supposed to win; they had the advantage in terms of raw strength.
On paper, their strength is...
Xie Wenjun.
But he's not even as good as Shubenkov.
Even the two people who surpassed him later were not as good as him.
but.
But he ultimately succeeded in turning the tables and killing the enemy.
The one who laughs last laughs best.
Shubenkov could only get fourth place.
The time was 11.22 seconds.
0.01 seconds.
They lost their bronze medal.
"Xie Wenjun, you've won the bronze medal!"
"He became the first Asian athlete to win a bronze medal since Liu Xiang!!!!!!!!!"
"Xie Wenjun, bronze medal!!!!!!!!!"
"Third place!!!!!"
"Incredible!!!!"
It is indeed incredible.
Because you should look at the person involved.
On one's own face.
It also says something incredible.
incredible.
And so on.
Liu Xiang stared at it, somewhat stunned.
But he reacted quickly.
Through the television screen.
He clapped his hands gently and repeatedly.
My previous worries about leaving.
this moment.
The smoke disappeared.
Even a sense of relief.
A surge of emotion welled up in my mind.
Su Shen looked at it.
It's a smile on the corner of his mouth.
Xie Wenjun won the card.
This means.
history.
changed.
Things have changed.
this year.
Our track and field team.
The second half of the struggle begins.
just began.
