Chapter 2016: Curved arm vs. curved arm! Everyone is showing off their special abilities
Bang——
Gunfire rang out.
Four people rushed out from the starting line at the same time.
The fastest among them are Xie Zhengye and Zhou Bing.
The two people set up their arms and started running.
Xie Zhengye The chemical energy of the human body is converted into mechanical energy through muscle contraction. When starting, muscle contraction drives the arms to swing rapidly. This rapid mechanical movement efficiently transfers energy to the entire body. From a biomechanical perspective, the frequency of muscle contraction is related to
The arm crank drive frequency is matched to provide continuous power for starting acceleration in the form of high-frequency energy output. It is like an efficient energy transmission chain, ensuring that energy is quickly and continuously converted into forward kinetic energy.
Zhou Bing said that when the arms are started to swing significantly, according to the law of conservation of momentum, the entire body will gain a larger reverse momentum, which will be further utilized when the legs are extended. During the stretching process, the leg muscles are subjected to
The momentum effect generated by the swing of the crank arm can more fully exert the force, thereby increasing the stride length.
And compared with Xie Zhengye, in terms of energy conversion, Zhou Bing's large arm swings when starting require more muscle energy reserves. When muscles contract and stretch significantly, they convert a large amount of chemical energy into mechanical energy. Unlike Xie Zhengye,
His energy is more concentrated on a single larger movement to ensure that the legs have enough strength to stretch when starting and achieve a larger stride.
The separation was not so obvious before.
Now put it all together.
The comparison is more intuitive.
Compared with Xie Zhengye, Zhou Bing adopts a squatting starting posture that is more conducive to taking advantage of his stride before starting. The distance between the front and back of the feet, the degree of knee bend, etc. must be accurately adjusted according to his physical conditions and habits to ensure the starting moment.
Can obtain maximum forward thrust.
The center of gravity of the body should be moved forward as much as possible, like a compressed spring, to accumulate strength for the long stride after starting.
I saw him bending the front knee to about 90 degrees and the rear knee to a slightly smaller angle. This allowed him to better utilize the explosive power of his leg muscles at the start and lay the foundation for his subsequent stride advantage.
After starting a run, the swing of the arms should be closely coordinated with the movement of the legs. When the arms swing back forcefully, it will drive the body to move forward and upward. At this time, the legs should take advantage of the trend and take larger steps.
When Xie Zhengye starts running with his arms bent, his arm swing frequency is high. At the moment of starting, the rapid arm swing can drive the body forward quickly, providing strong power for acceleration after starting. For example, in the first few steps after starting, he
Rapidly obtain forward propulsion through high-frequency arm swings, putting the body into an accelerated state quickly.
When starting with bent arms, the movement of the arms can help Xie Zhengye better coordinate the balance of the body. During high-speed starts and acceleration, the balance of the body is very important. A slight imbalance may affect the speed. The fast-swinging arms can to a certain extent
It helps the body maintain stability and enables the legs to exert force more effectively, thereby achieving quick start and acceleration.
Secondly, from the perspective of efficient power transmission - Xie Zhengye's bent-arm posture allows the power of the arms to be better transmitted to the core part of the body, and then transmitted to the legs through the core part, thereby enhancing the explosive power of the legs.
This kind of power transmission is coherent and efficient, allowing Xie Zhengye to quickly increase his speed in a short period of time after starting. For example, at the starting stage of the race, his arm-curving movement can quickly transfer the power of his arms to his legs, allowing him to
His starting speed was significantly better than before.
At the same time, the arm swings and leg movements work closely together to form a coordinated movement system. During starting and acceleration, the swing rhythm of the arms echoes the kicking rhythm of the legs, jointly providing powerful power to the body.
This kind of cooperation makes Xie Zhengye's overall movements smoother and his explosive power can be fully utilized.
Because the two of them were on the road.
This time it seemed like it was all a crank start.
But the difference is extremely obvious.
This is also everyone’s technical training and unique charm.
It is not carved out of a mold like an assembly line. It is a personalized upgrade of personal physiological conditions based on the same scientific concept.
This is also the fascinating part of exercise science.
Comparing Zhou Bing and Xie Zhengye: Xie Zhengye's starting posture is relatively standard and stable. He stands with his feet forward and backward, the knee of the front foot bends at an angle of about 90 degrees to 100 degrees, the knee of the back foot bends slightly less, the body leans forward, and the center of gravity is forward but maintains balance.
.This posture can make the body act like a compressed spring, storing and releasing greater elastic potential energy at the moment of starting, converting it into forward kinetic energy, helping him to start the crank arm quickly.
Then rushed out.
Shift of focus.
During the starting process, he can accurately control the smooth transfer of the body's center of gravity. From the preparation position to the first step of the start, the center of gravity gradually moves forward and upward, and at the same time, in conjunction with the leg extension and arm swing, the body can move along a straight line.
Accelerate quickly, reduce energy dispersion and unnecessary lateral shaking, and improve starting efficiency.
In addition, Xie Zhengye's reaction to this shot was faster.
He's on startup.
He took the lead.
Suppressed Zhou Bing.
Although Zhou Bing was also surprised that a little boy like Xie Zhengye could master the curved arm start so quickly that it took him so many years to achieve a breakthrough...
But he still had a competitive mind.
There is no way not to compete.
It's all the same startup action.
How is it possible that they are not competing against each other?
In the first four steps after starting, Xie Zhengye used high-frequency arm swings to drive rapid alternation of his legs.
The arms swing rapidly and rhythmically, and each swing strongly pushes the body forward, allowing the legs to take steps at a high frequency. At this stage, his stride length is relatively small, but due to the extremely fast cadence, he can
Achieve a high speed in a short period of time, quickly complete the initial acceleration of the start, quickly open the gap with the opponent within a short distance after the start, and seize the leading position.
Here, Xie Zhengye relies on crank-arm starts, which increases the frequency of starting steps.
This chapter is not over yet, please click on the next page to continue reading! You can see that his first four steps are coherent and compact, and his body leans forward at a suitable angle, like a taut bowstring.
Full of speed.
In the first four steps after starting, Zhou Bing's arm swings are larger. The focus is to create good conditions for the legs to exert force to increase the stride length.
His first step is mainly to send the body's center of gravity forward and upward smoothly through the powerful swing of his arms and the extension of his legs. The following three steps gradually increase the stride length.
This means that although his speed did not increase as fast as Xie Zhengye's in the first four steps, the distance of each step gradually increased, laying the foundation for subsequent larger strides.
Unexpectedly, after Su Shen and Zhao Haohuan.
Two people started a curved arm battle again.
Different from the group of Su Shen and Zhao Haohuan, Su Zhao's previous starting ability was too different, and the height difference was also too big, so it was inappropriate to compare them together.
Xie Zhengye and Zhou Bing are both 200-meter athletes.
The confrontation becomes more evenly matched.
Because the others did not have the ability to start with a bent arm, the entire golden four steps plus the start of the first 10 meters became a stage of confrontation between Zhou Bing and Xie Zhengye.
Even Liang Jiahong.
I can't get involved here either.
As the number of steps increases, Xie Zhengye still maintains a high step frequency, and the coordination of his arms and legs becomes smoother because his speed continues to increase.
At this time, his speed has increased significantly, and his body has gradually entered a more stable acceleration state.
His stride length may increase slightly while remaining stable, mainly by further optimizing the coordinated movements of his arms and legs and using the power generated by arm swings to more fully promote leg extension, thereby shortening the distance after starting.
Continue to expand the advantage within the distance and prepare for the subsequent acceleration stage.
For Zhou Bing, the last few steps were a process of gradually enlarging his stride length. The larger swings of his arms continued to provide power for his legs, making his stride length get bigger and bigger in these seven steps.
At five, six or seven steps, his stride advantage began to become more obvious, and the distance covered by each step was greater than that of Xie Zhengye. Although his speed may be slightly slower at the beginning of the start, he has begun to gradually catch up at this stage.
Zhou Bing did not grow up eating nothing.
I have been practicing this technique for so many years.
At this point.
Compare Xie Zhengye.
Not to mention more concessions.
They all started with bent arms.
The direction of development is completely different.
It’s also a wonderful sight.
The moment Xie Zhengye starts running, his neuromuscular system is highly coordinated. His cranked-arm starting technique shows typical high-step frequency characteristics, fast muscle fibers are rapidly activated, and muscle contraction produces powerful explosive force.
Zhou Bing's arm swing angle and amplitude are carefully adjusted, using the eccentric and concentric contraction of the muscles to generate greater momentum. This momentum is transmitted to the legs through the body's kinetic chain, providing strong support for the leg extension, thus
Achieve larger strides.
But it's only ten meters.
After passing ten meters.
At the beginning of the acceleration zone, Xie Zhengye began to suppress clearly.
Cadence further increases with speed.
The previous situation of insufficient cadence has been greatly improved.
This stable high stride frequency benefits from the isokinetic contraction ability of the muscles, making the force output uniform and efficient.
The rhythm of arm swinging and leg stretching is highly consistent, forming a stable dynamic rhythm.
As the number of steps increases, the stride length is gradually optimized and increased driven by a stable high stride frequency, and the body's acceleration process is smooth and rapid.
Although Zhou Bing also wants to continue to create greater pushing and extending force for his legs and further expand his stride length.
However, during this process, due to the need to adjust the body's center of gravity and movement posture to adapt to the increase in stride length, the complexity of the movements causes a slight decrease in step frequency.
Although the increasing stride length gradually increases the speed, the overall acceleration efficiency is slightly inferior to that of Xie Zhengye, and the speed increase is slightly less consistent.
So starting from twenty meters away, Xie Zhengye gradually accelerated and pulled him forward.
If Zhou Bing could hear Xie Zhengye's voice, he would definitely be furious...
Goodbye pancake brother.
Spread the oil.
Zhou Bing was angry, but he didn't know how amazing what he was doing now was.
He is a person who used to rely entirely on the back-end to make a living.
At least that's what most people think.
Including Liang Jiahong.
Who knew that he would suddenly start his career with Xie Zhengye here and suppress himself greatly.
Last year.
He is a winter training test.
Keep running on top of everyone.
Including Zhou Bing and Xie Zhengye.
Only the front was held down a little by Wen Yongyi.
Ke Wen Yongyi specializes in the 60 meters and is a medalist at the World Indoor Championships. It is normal to compete with him here.
Besides, when it comes to Wen Yongyi, no one else can stop him.
I thought that Wen Yongyi and Xu Zhouzheng would finish the race as soon as they were in the first group.
My group should be easy.
result……
Xie Zhengye and Zhou Bing.
He actually killed him right in front of him.
I forced myself to run again.
Forget it.
These two are both people who are mainly behind, and they are ahead of themselves. What's going on?
Liang Jiahong was almost furious.
He completed the entire adjustment during winter training last year, which affected his startup and acceleration, not as fast as before. However, the consequence of this sacrifice is the optimization of the entire process.
Take the balanced route.
It became his choice.
If you choose this path, it will be impossible to be the same as before. If you don't see the extremely balanced Blake, you won't be able to take advantage of the Soviet Union Bolt and Powell.
I originally wanted to take it a step further this year.
The technology is more sophisticated and systematic.
The starting power is also optimized...
In the past, the distribution of starting force may not be reasonable enough, and part of the force was wasted or failed to play its full role during the starting process. This year's winter training, after training, the strength of various parts of the body can work better together, and the force is concentrated on the starting action.
, making the initial explosive power stronger.
I thought it should be better.
Of course the reality is better.
But it is.
These two started with crank arms.
Suppressed all his edge.
It seems like he has not improved at all.
This is really shocking.
Two players who are good at running from the back are suppressing themselves from the front. So how can they run?
Isn't it even more hopeless after this?
In the end, God is still fair.
In other words, these two people have just mastered the crank-arm start, and many things are in a state of gain and loss. For example, Zhou Bing is a bit similar to Zhao Haohuan who has just started to master the crank-arm start, and the benefits from starting to accelerating are rapidly diminishing.
Now all his focus is on applying this technology in actual combat.
I haven't thought about the rest yet.
The most important thing is that his own strength is not that strong. He finally made a strong move in the front, so he still has to fall back.
Liang Jiahong saw Zhou Bing's speed drop.
Immediately make efforts to catch up.
Similar to Zhou Bing, Xie Zhengye's speed has also slowed down.
It’s just that Xie Zhengye’s own strength is stronger.
The decline here is not that big and obvious.
But they were all captured by Liang Jiahong.
This immediately made him happy.
Otherwise, how can we play it later?
If you can't establish a leading trend in the front, it's really hard to tell what's next.
In fact, it can be seen that Liang Jiahong has definitely improved this year. Whether it is the starting posture, the kicking and stretching of the legs, the swing of the arms, etc., he can maintain a high degree of consistency and stability, which can all contribute to subsequent acceleration.
And something that lays a good foundation for running on the road.
Because of this, he is actually very ambitious this year.
Xie Zhengye was first, Zhou Bing was second, and Liang Jiahong was third.
But after entering the road, run.
Things have changed somewhat.
The preparation Liang Jiahong made before is now beginning to come into play. Compared with last year, his more refined skills also allow him to better distribute his physical strength during the run.
In the past, maybe due to the large difference in ability between the front and rear sections, it was easy to lose physical strength and slow down in the second half of the run. This was especially true during the fight against Xie Zhengye last year.
In winter, he began to focus on strengthening. Now, all parts of his body can work together efficiently, and his cardiopulmonary function, muscle endurance and other aspects have been developed in a balanced manner.
This can maintain a relatively stable speed over a longer distance, reduce speed fluctuations, and make the entire running process smoother and more efficient.
at the same time.
His hip delivery finally began to have the faint shadow of his own unique system. This is what every elite athlete needs to do if he wants to become a further world-class athlete.
You cannot combine the technical system with your own unique style to form your own unique system.
It will be difficult for you to complete further transformation.
It is very likely that you will get stuck at a certain point and it will be difficult to make any further progress.
Liang Jiahong can indeed do it.
He is indeed a man who was delayed by a broken bone.
It's fine now.
He is starting to move towards his ultimate talent more and more.
Is there any opportunity to open 10 seconds?
With the support of my scientific system and technology this time, can I have a chance to hit 10 seconds?
Su Shen also wants to know.
40 meters 50 meters.
Bang, bang, bang, bang, bang.
Bang, bang, bang, bang, bang.
Bang, bang, bang, bang, bang.
During the 20 meters of running, several people were showing off their talents.
Seeing Liang Jiahong gradually starting to catch up, Yuan Guoqiang's complexion also improved a lot.
Otherwise, he would be really worried.
As a disciple, has he reached his limit and can no longer keep up with the advance of these large troops?
Extremely fast explosion.
Liang Jiahong also did better here this year.
The stride length and stride frequency of each step can reach an optimal combination point. The swing of the legs is more powerful, the landing is lighter, and the forward angle of the body is more reasonable, reducing unnecessary energy consumption.
After all, he still has more experience.
Get in touch with the Sushen system earlier here.
Coupled with his own talent, he is already pretty good.
