The Su God of the Reopening of the Sports Arena

Chapter 2214 They all start with bent arms, but you are more noble?

Qingtang City Central Stadium.

"Everyone take your place."

The electronic password rang.

The athletes are all ready for their starting position.

Su, Zhou and Xie each started with bent arms.

It's just that everyone's different postures are different.

Xie Zhengye runs with bent arms and he also uses light-load and high-frequency dumbbell arm swing training to strengthen the stability of the rotator cuff muscles and avoid excessive muscle gain that affects the frequency of arm swing.

Combining depth jumps with resistance sprints can enhance the eccentric contraction capacity of the hamstring muscles and shorten the ground contact time.

Through hanging leg raises and gravity ball rotations, the rigidity of the transverse abdominal muscles and erector spinae muscles can be enhanced, and the energy transfer loss of bent arms can be reduced.

Overall it was very well done.

As expected, I have entered a period of explosive growth. At the age of 19, everything I do starts to get on high speed.

Xie Zhenye's starting posture is relatively standard and stable. He stands with his feet forward and backward, with the front knee bent at an angle of about 90 to 100 degrees.

Bend the back knee slightly and lean forward, keeping your center of gravity forward but balanced.

This posture allows the body to store and release greater elastic potential energy like a compressed spring at the moment of starting, converting it into forward kinetic energy, helping him to start quickly with his arms bent.

From the perspective of mechanics, his current posture of leaning forward appropriately can move the body's center of gravity forward, allowing gravity to generate a component force in the horizontal direction, thus helping to accelerate forward when starting.

At the same time, this angle also allows his leg muscles to be in a good state of force when he pushes off the ground, making it easier to efficiently convert force into forward propulsion. It also helps to maintain body balance at the moment of starting and avoid falling due to excessive forward leaning.

After bending the arms, the arm's moment of inertia decreases. According to the principle of conservation of angular momentum, under the action of the same muscle torque, the angular velocity of the arm swing will increase, so that a shearing action can be performed quickly, driving the body to rush forward quickly.

"preparation."

Before starting the race, Zhou Bing adopted a crouching starting posture which was more conducive to taking advantage of his stride.

The distance between the feet and the degree of knee bending should be adjusted precisely according to your physical condition and habits.

To ensure maximum forward thrust at the start moment.

The body's center of gravity should be moved forward as much as possible, like a compressed spring, to accumulate strength for the big strides after the start.

Bend your front knee to approximately 90 degrees.

The back knee should bend at a slightly smaller angle.

This will allow you to better utilize the explosive power of your leg muscles when starting, laying the foundation for subsequent stride advantages.

When bending your arms, the angle and strength of your arms should be just right.

If the degree of arm bending is too great, it may affect the speed and amplitude of the arm swing; if it is too small, the advantages of bent-arm start cannot be fully utilized.

In the ready position, the arm muscles should be kept moderately tense so that they can swing quickly and forcefully after hearing the gunshot.

One of the two people focuses on stride frequency when starting, while the other focuses on stride length.

Each has its own merits.

Just like Su Shen's start, he pays more attention to step frequency, while Zhao Haohuan tends to focus more on stride length.

A meaning.

At this point, it depends on who can integrate this with their own body better and more closely.

“Both did a great job.”

Zhao Haohuan commented on the side.

It's great to get such an evaluation from him.

but……

He turned his eyes.

Jumped to another one.

But this is not as good as Su Shen's side.

No matter how many times you watch it.

They are all so excellent.

It’s as if I can give myself extra guidance every time.

No matter which time you watch it, it seems to be able to bring forth something new and fresh.

In the preparation stage for the start, Su Shen's control of the angle of his body leaning forward was extremely precise.

In Zhao Haohuan's eyes, this angle is not set arbitrarily, but has a scientific basis.

Proper forward leaning can significantly move the body's center of gravity forward, allowing gravity to produce a component of force in the horizontal direction.

According to the decomposition formula of gravity, gravity G can be decomposed into vertical component G and horizontal component G, G= G× sinθ, θ is the forward lean angle of the body. As the forward lean angle θ increases, the horizontal component G increases, thereby helping to accelerate forward when starting.

At the same time, this forward tilt angle allows Su Shen's leg muscles to be in the best force state at the moment of pushing off the ground, like a fully drawn bow, which can efficiently convert force into forward propulsion.

Moreover, a reasonable forward lean angle can also help maintain body balance at the starting moment and prevent the body from losing control and falling due to excessive forward leaning.

But Su Shen's pressure is obviously lower than that of the other two.

Why is the pressure lower? Don’t they want to?

Or because.

My own strength cannot match this focus.

Under this center of gravity condition, it is easy to go awry, or it may be difficult to exert force, or excessive energy will be consumed to maintain the movement.

This shows that Su Shen has strong upper body strength and core stability.

at this point.

Even Zhao Haohuan finds it difficult to do so now.

Of course, it is also because his physical condition is not suitable for this.

It takes more effort to achieve this.

Because he is too tall.

The more pressure you put on the machine, the greater the energy consumption will be.

Su Shen is just over 1 meters tall, so he would consume less energy in this regard and it would be easier for him to do it.

But even so.

It is still too difficult to maintain such an action here.

If the forward lean angle is too large, the stability of the body will be seriously threatened, and it is easy to lose balance when pushing off the ground, affecting the effect of the start.

However, if the forward tilt angle is too small, the horizontal component of gravity will be insufficient, and gravity cannot be fully utilized to assist the start, making it difficult to obtain a high initial velocity at the start.

A dilemma.

Of course there is one more thing.

Zhao Haohuan saw some doubts here.

That is Su Shen...

Is this posture a bit too much?

It's too low.

The referee's command was fine when it came to "on your marks".

After entering the "preparation" state, Su Shen immediately pushed his center of gravity forward more.

Ok?
None of this could be hidden from Zhao Haohuan's eyes.

joke.

He is now also a master of the bent-arm start.

Except for Su Shen.

He is the person who has mastered this technology best so far.

none of them.

So it seemed to him.

Even though Zhou Bing and Xie Zhengye have done a very good job, there are still many problems and flaws.

And Su Shen's side looks so comfortable, stable and strong.

No matter when you look at it, it always remains in perfect condition.

At least he looked perfect.

At least he couldn't see anything wrong with it.

You can say that it is because his current level is not high enough to see more problems, but he is already the second person in the world to use this technology.

But when the electronic password shows "Ready".

Instead, he seemed to have noticed some problems.

Su Shen this...

Is it a bit too much pressure?
Would this focus be too much?
can.

Such a simple question.

You can see it yourself.

Can't he see it, can't he feel it himself?
impossible.

Or after a hundred meters of continuous consumption.

He hasn't recovered yet.

His nerves were tired and his muscles were not yet elastic, yet he was forced to assume this posture, which was naturally different from his usual neutral posture.

You know, the bent-arm starting posture that Su Shen usually adopts definitely contains profound biomechanical principles.

Zhao Haohuan firmly believes in this.

When he heard the command "ready", his arms with bent elbows were in a state that was both relaxed and ready to go.

This state is difficult to achieve.

At least the other few people can't do it.

Zhao Haohuan also has a difficult time.

Because this requires more proprioception to be involved.

Allow your muscles to naturally enter a fixed pattern without your control.

This will naturally reduce the consumption during support.

It feels like being in a relaxed posture.

But in fact, the muscles have completed the force structure without any subjective participation.

That’s the benefit of proprioception.

Friends who regularly exercise and lift weights will definitely be able to feel that one day your strength improves or your condition is particularly good.

Take the bench press as an example. Originally you would feel that 100 kilograms is extremely heavy, but suddenly one day when you stand up, you will feel that it has become a lot lighter.

But has the 100 kg weight actually become loose?
Of course not.

Is gravity playing tricks on you?
Of course it's impossible.

Gravity makes everyone equal.

In fact, it is because of your muscle strength and something that you have not explored in more depth, proprioception.

It got better.

Naturally, in the same posture and force pattern, you can complete it without mobilizing more neural strength.

For example, Su Shen.

From the perspective of moment of inertia, the moment of inertia of the arm decreases after the elbow is bent.

The calculation formula of the moment of inertia I is I = ∫rdm, r is the vertical distance from the mass point to the rotation axis, dm is the mass of the mass point, and bending the elbow reduces the vertical distance r from each mass point on the arm to the rotation axis of the shoulder, thereby reducing the moment of inertia I. According to the principle of conservation of angular momentum, during the arm swing process, the angular momentum L = Iω, ω is the angular velocity and remains unchanged. When the moment of inertia I decreases, the angular velocity ω will increase.

This means that with the same muscle torque...

Su Shen's arms are now bent and can swing at a faster speed.

Thereby making the shearing action faster.

Drive your body forward forcefully.

Even his bent-arm starting posture allows him to adjust his body posture more flexibly at the moment of starting.

Quickly enter the accelerated state after the golden three steps.

Compared with the above two, Su Shen is...

The bent-arm start has a smaller range of motion.

Muscles react faster.

Capable of producing greater acceleration in a short period of time.

But Zhao Haohuan didn’t notice it.

Of course, he didn't see that there was another problem.

That is.

Indeed
Su Shen had never done a forward pressure of such high intensity before.

That's because it's done in the plains.

It is indeed difficult.

The physical burden is particularly heavy now.

but.

In Qingtang City.

It can indeed be done.

Su Shen already knew it when he came here for a test run this time.

Now it’s just a matter of putting it into practice.

Just show it in actual combat.

This……

See Su Shen and the others.

Bend your arms and spread them out front and back.

These traditional players feel themselves.

It's really embarrassing.

It feels like I lost momentum right from the start with my technique.

I am the starting point.

It's like a product of the last century.

It seems a bit out of place here.

And it is obvious that the opposite side is the minority.

They are the majority here.

But now I always give him a feeling...

They feel like they are in the minority.

This is a very strange illusion.

Quite quite strange.

But it does exist.

This is because they have already realized it more or less in their hearts.

That kind of technology.

As long as you master it.

It will most likely be better than the current one.

There is envy and jealousy that you cannot taste.

Of course, it is more about self-confidence and confidence.

Because not everyone can master this technology.

It doesn't mean that everyone can adapt to this technology.

It doesn’t mean that you can’t run fast if you don’t master this technique.

if so.

These athletes internationally.

Isn't it still the same using the traditional startup mode, opening in 10 seconds, or even 9 seconds or even higher?
This is entirely due to one's lack of ability and confidence, which leads to bad psychology.

Liang Jiahong was embarrassed.

Every time I run 200 meters.

Yang Jian always introduces the specialty of Ersha Island, the bent-arm start.

It makes me feel like I’m not from Ersha Island.

This is very unfair.

Obviously myself.

He is also a player who broke 10.

Don’t worry about whether it’s high altitude or high wind speed.

Anyway, my resume has exceeded 10 now.

Why do you seem so unconfident here?

I even feel a little aggrieved.

Crank-arm start.

It's not that he doesn't want to train, but he has too many things to practice on a daily basis, and he didn't start practicing this since he was a child. He suddenly changed his career and started practicing, so his overall strength was greatly reduced. He doesn't have time to gamble now.

sometimes.

He glanced over.

I really envy Zhou Bing and Xie Zhengye and others.

Or he has been following Su Shen from the beginning.

Or else.

At the beginning, he was recruited to Ersha Island for training at a very young age.

He doesn't have such conditions.

I also went through a period of slacking back then.

I also lay down for a while.

He also felt somewhat regretful about this matter.

It would have been great if I had switched to learning as soon as I saw Su Shen and others join the team.

After all, only Su Shen and Zhao Haohuan knew how to do it back then.

Even the latter was barely mastered around the National Games.

I didn’t know how to do it when I first came to Ersha Island.

You can only spend time practicing little by little.

But he thought at the time that only domestic super geniuses like Su Shen and Zhao Haohuan could master such amazing skills.

Zhou Bing has been training for so many years.

Always taking time.

Didn’t you fail to practice it?

But he didn't give up and spent nearly 10 years.

Finally did it.

This kind of shock.

The power of persistence.

And persist until success.

It also stimulated him.

This year it will exceed 10.

It’s not just because Su Shen has given all domestic athletes the plateau buff.

And his own heart.

I began to seriously examine my own naivety and regrets during that period of time.

Start to examine yourself seriously.

It is the first step to improvement.

Because people are often unwilling to do things.

It means criticizing yourself.

It is easy to criticize others.

Self-criticism is difficult.

Liang Jiahong.

It was only in recent years that I reluctantly realized this truth.

Why stick to being yourself, Taikula.

Have you ever thought about a question, if the path you insist on is wrong, if you keep using this sentence to cover up your mistakes.

Then you will only go further and further down the wrong path.

If you stick to the right thing, it is of course right, but what if it is the wrong thing?
Insisting on doing it will only make things worse.

It will only waste time and gain nothing.

But sometimes people may accept criticism from others, so self-criticism is actually a great art.

After Liang Jiahong broke 10, his inner demons and knots were resolved.

What he's going to do now.

It also took two years of calmness and precipitation.

It's just right to take advantage of the two years without a world championship after the end of Moscow.

Polish yourself well.

Bang————————

Gunfire rang out.

Game start.

As a result, Su Shen went out.

This made Zhao Haohuan's eyes widen.

This……

how is this possible? ? ?
