Chapter 2024 Little monkey, want to jump out of Huaguo Mountain?
Bang——————
The game begins.
The fastest responder was... Liang Jiahong.
He is in the third lane, seemingly at the back, but there may be no pressure when starting the shot, and it feels good.
At this stage, he is highly focused, his brain issues instructions quickly, his nerves react extremely quickly, and his muscles respond instantly, producing powerful explosive power.
It's only 0.125s.
The leg muscles contract rapidly at the moment of starting. The contraction speed of muscle fibers may reach 5-7 meters per second. The strong kicking force pushes the body forward, and the kicking force generated can reach 3-4 times of the body weight. He weighs 85 kilograms.
, the pushing force at this moment may reach between 225kg and 300kg.
Let his body jumpstart.
Get off the starting block.
I am actually the fastest to start?
However, you won’t be happy for even a second, and you will soon be taught how to behave.
Because of the other three people.
It's all...a crank start.
That's right.
Zhou Bing, Xie Zhengye, Su Shen.
All three.
Start from the fourth lane and go to the sixth lane.
All three people are ready with bent arms.
It's just that Liang Jiahong's feeling in the third lane is not so clear, but in the eyes of others...
A wonder.
Xie Zhengye soon understood why Su Shen strongly recommended him to learn to start with a bent arm.
This is obvious for straight events, but actually for 200 meters...
It is also of great significance.
The start of the 200-meter curve is to enter the curve. According to the centripetal force formula F = m v2/r. Where F is the centripetal force, m is the mass, v is the speed, and r is the curve radius. To run the 200-meter curve, you need to tilt your body inward.
Balance centrifugal force.
The arm-bending movement allows athletes to adjust their body posture more flexibly, allowing the body's center of gravity to shift moderately inward.
Increase centripetal force.
Reduce the possibility of deviating from the runway due to excessive centrifugal force, thereby maintaining a good running trajectory when starting in a corner.
In other words - when starting in a curve, starting with a bent arm helps athletes better adapt to the centrifugal force of the curve.
Then this way.
The feeling is completely different from before.
In the past, when straight-arm starts were started in a curve, the adjustment of the body's center of gravity was relatively inflexible. Due to the extension of the arms, the overall moment of inertia of the body is large, and it was difficult for athletes to quickly adjust the body's center of gravity to tilt inward to balance the centrifugal force when starting in a curve.
This may cause you to spend more time adapting to the curvature of the curve when entering the curve, and may even cause you to briefly deviate from the inside of the track due to centrifugal force.
Not to mention that according to the centripetal force formula, the center of gravity of the body is relatively outward when the arms are straight, which is not conducive to quickly generating enough centripetal force to resist the centrifugal force. It may affect the stability of the running trajectory in the early stage of curve acceleration after starting.
The bent-arm start allows athletes to more quickly adjust their body's center of gravity when starting in a curve. Arm bending reduces the moment of inertia, and athletes can easily tilt their body's center of gravity inward to increase centripetal force.
This rapid adjustment of the body's center of gravity helps athletes better follow the curve at the start and reduces the interference of centrifugal force on starting acceleration.
So from the start, Xie Zhengye was able to get a sense of coordination through the swing of the bent arm and the tilt of the body when starting with a bent arm.
This allows the body to be in a posture that is conducive to balancing centrifugal force at the moment the curve starts.
This is something that a straight-arm start does not have.
It can better create good conditions for subsequent corner acceleration.
No wonder Mr. Su ran 200 meters so hard before. This time I finally know...
Then this time!
I won't lose!
Zhou Bing is similar here. He feels that in terms of power transmission when starting in a corner, the efficiency of straight-arm starting is... relatively much lower than that of a curved arm.
Moreover, when the arms are straight, the angle between the contraction direction of the arm muscles and the tangent direction of the curve, that is, the main direction of the athlete's forward acceleration, is relatively large, causing part of the force to be dispersed when the leg kicking force is transmitted through the body to the forward direction.
This issue cannot be changed just by changing it if you want.
Zhou Bing tried it.
Basically in the straight arm starting state.
Can't be comprehensive.
No matter what you do, you will lose sight of one thing.
This causes the athlete's forward power output to be insufficiently concentrated during the acceleration process after starting the curve.
It is not conducive to quickly increasing speed in the early stages of corners.
Especially those with a future like my own who are "difficult to start".
It is even more impossible to exploit strengths and avoid weaknesses.
There is no way to rush through this stage quickly like Su Shen.
Furthermore, my body coordination is not as good as that of people like Su Shen on curves. This means that on curves, after straight-arm starting, the body needs extra strength to correct the tendency of deviating from the tangent direction of the track that may be caused by the dispersion of strength.
This will also consume energy to a certain extent and affect the acceleration effect when starting corners.
Let yourself start by not being rich in the first place.
To make matters worse.
Unfortunately, I still have no solution at all.
It’s nerve-wracking.
It's fine now.
When starting with a bent arm, the bent arm makes the angle between the direction of muscle contraction and the tangent direction of the curve smaller.
Power transfer is more direct and efficient.
This allows the leg pushing force to be better transformed into a resultant force forward and to the inside of the bend through the crank arm swing.
Help yourself to accelerate quickly in the tangential direction when starting a corner.
At the same time, it also helps the body tilt inward to balance the centrifugal force.
Zhou Bing felt it in the 0-10 meter stage after starting - the crank arm start can help him obtain the tangential speed required for the curve faster.
He immediately adjusted his body and combined with tilting movements to make the acceleration process smoother.
This is what the spectators below looked like, and everyone thought they had seen it wrong.
Are these still Xie Zhengye and Zhou Bing?
Is this still the 200-meter curved start for us Asians???
In the past, except Su Shen.
Even Xie Zhengye, who uses the Jamaican running method, is not as strong as the West African black man at the moment of start due to his ability to start. It is always interesting to see how close he is.
This is because first, when starting with straight arms, it is more difficult to control the arm swing in the direction of the curve.
However, Xie Zhengye and others do not have the advantage of West African blacks. Due to the advantage of arm extension, the swing amplitude is relatively small and insufficient. During the start of the curve, it is more difficult to accurately control the direction of the arm swing to assist the body along the inside of the curve.
go ahead.
Especially for the 200-meter curve start, which requires high starting direction and trajectory accuracy, the straight arm swing of Chinese athletes may make it difficult for athletes to accurately grasp the position of the body on the curve at the moment of starting.
The disadvantage of wingspan is magnified here.
But now after a cranked-arm start, the arm swing during a cranked-arm start is more conducive to controlling the direction of the curve. The swing range of the bent arms is relatively small and more controllable. Athletes can accurately adjust according to the curve of the curve and their own speed.
The direction and force of arm swing.
The disadvantage of wingspan is greatly reduced.
For example, Xie Zhengye now controls the swing of the curved arm when starting a curve, and his right arm appropriately increases the force of the inward swing for counterclockwise curves.
Properly controlling the force of the outward swing of the left arm can more accurately guide the body to accelerate along the inside of the curve.
Compared with the straight arm swing, the lateral force generated on the curve is relatively difficult to control. It is prone to excessive outward or inward force components, causing the body to swing unnecessarily during the starting stage of the curve, affecting the starting speed and directional stability.
Sexual problems, now also because of the use of a curved arm...the problem has suddenly reduced.
Xie Zhengye’s own feeling is that this precise control of the arm swing direction can help athletes better adapt to the change in curvature of the curve during the starting stage of the curve.
It can also maintain the correct trajectory of the body on the curve, reducing speed loss and the risk of fouls caused by directional deviation.
It’s really just one word – cow.
Two words - awesome.
With this hand, a large part of the starting disadvantage of black people of West African descent can be solved.
No wonder I raised this question before.
Ning Dehai didn't care at all.
Also let yourself practice well.
Don't think so much.
Now it looks like...
snort.
Ning Ma must have known about it for a long time.
After the crank start is completed.
You can put these straight-arm starting problems inside.
Solved easily.
So at that time.
There is really no need to waste time thinking about it.
Do basic training well.
That's enough.
Zhou Bing also ran well.
In straight-arm starts, it is difficult to maintain body balance after the start of the curve. Now it is no longer a problem. After the start of the start, since the arms are no longer stretched so much, the body is subject to the dual effects of centrifugal force and acceleration force on the curve, and it is easier to
Quickly adjust posture to maintain balance.
I saw that Zhou Bing, who usually started out very ordinary and inconspicuous, suddenly seemed to be a different person.
Visible to the naked eye, you can adjust your body posture more flexibly.
By fine-tuning the swing of the curved arm, body tilt angle, etc., it can effectively cope with the centrifugal force and acceleration force on the curve.
After cutting into the curve, the cranked-arm start can keep the body balanced during dynamic changes, providing a guarantee for Zhou Bing to accelerate stably on the curve.
Whether it's Xie Zhengye or Zhou Bing.
This is all because of the body balance brought about by crank arm activation, allowing them to focus more on speed improvement and curve trajectory control.
Plus reduce energy loss and speed fluctuations caused by balance issues.
This startup is completely different from before. He is a completely different person.
Then there is a ghost.
"So fast?"
"Is this still Zhou Bing?"
"Thank you kid, why are you so scary?"
Even the first-line team members felt as if they were looking at the wrong person.
These two people are completely different from what they were in the impression.
Instead, it seems to have become...
Su Shen's appearance.
No wonder Xie Zhengye was full of confidence in his shot.
Feelings are what he feels.
I have already activated as much as Su Shen.
If Su Shen cannot gain a lot of advantages in the front.
It is indeed difficult to beat Xie Zhengye, a top speed athlete in history.
Mr. Su.
I'm sorry this time.
Your whipping of my love...
It's about to end.
you……
I……
Grass……???
Xie Zhengye was thinking happily about the scene after he defeated Su Shen.
The next second.
Just in front of yourself.
Not only did the red figure not shrink.
On the contrary...
Stretched.
He even quickly approached the outermost Zhou Bing in front.
There is only one possibility for such a situation to occur...
That's when Su Shen starts up.
Faster.
More vicious.
Stronger.
At this moment.
Xie Zhengye looked at the figure who was pulled in unexpectedly.
It felt like there was a head behind that figure, showing Su Shen's unique warm and innocent smile, saying:
There is progress.
But it's not enough.
The lash of love.
Still have to continue.
Can't stop yet.
It just feels like – you’ve seen Journey to the West, right?
Xie Zhengye originally thought that he had achieved Zhengguo, but he was a thousand miles away.
It feels like I can go anywhere.
Then I suddenly looked back and realized...
He actually still didn't jump out of Su Shen's Five Fingers Mountain.
