The Su God of the Reopening of the Sports Arena

Chapter 343 thump thump thump~Xia Xun's new technology arrives! (Ask for tickets~~~)

Ersha Island.

Guangdong Athletics Team.

Su Shen made a summer training plan, and at the same time prepared for the Xiangjiang match at the end of next month.

In fact, there was nothing to pay attention to in this battle. It was only because of the "challenge" of the Japanese team's Shingo Suezui that this small game suddenly attracted attention.

Now it is different from ten years later, it is still the era when Japan absolutely dominates the Asian sprint world.

Therefore, even if Guo Zihao speaks out, it must be upright and absolutely not cowardly. It can only make everyone applaud Guo Zihao's courage, and few people really think about winning.

But it is also this kind of external environment that allows everyone to prepare for the war under a more low-pressure public opinion.

According to the rules, there is no point in going to so many people. In order to ensure the victory of this battle, Yuan Guoqiang came up with a plan——

Su Shen, Zhao Haohuan, and Hu Kai accepted the appointment.

The rest can stay at the training base for training.

It's the right decision, because there's no need to go, of course...

Because Guangdong Province is very close to the other side, if you complete the formalities, you can even leave on the same day without any trouble.

Xiangjiang Xiangjiang is actually separated by a river from here.

For people in Guangdong Province, it is not that far away.

Su Shen continued to give everyone "classes", not only basic training courses, resistance training improvement of strength and physical fitness, but also technical improvement.Especially Zhao Haohuan and Hu Kai, they all have to make sexual adjustments, taking advantage of the relatively long period of time, and the whole body, Su Shen began to mention the areas he always wanted to improve, that is——

Improved arm swing.

During the winter training, because of the modification of the hip delivery, there is no time to modify this aspect.

Well now, the time for summer training is relatively complete. Except for one confrontation match, everyone's games are not too many.

It is just possible to complete the improvement in this area.

How to improve the swing arm?
There are also different opinions in this country, but as someone who has experienced it, Su Shen is very clear about the future trend——

Circular arm swing motion.

Yes, this is the latest direction of future swing arm technology research.

This system did not begin to be researched and published in China until around 2015, and it will be almost ten years before now.

In ten years, that is almost the pinnacle of one or even two generations of sprinters.

Therefore, it must be equipped.

……

"Arm swing movement? Is there a problem with our current arm swing movement?" A group of people also looked confused. They didn't know what Su Shen meant by this. At most, swinging arms pays attention to the norms, strength and frequency, and even messes with angles. It's over, what else can I do?
This also needs to be changed?

This, however, is completely wrong.

The quality of the arm swing technique is crucial to the improvement of performance.

"We all know that the effect of arm swing is to maintain balance. The faster the arm swing, the stronger the ability to drive the lower body. But do you know why arm swing has these effects? Besides these, are there other effects? Or , what else can be improved?"

Everyone was dumbfounded, and some people put forward sporadic arguments, such as "increasing speed", "increasing stride frequency" and "increasing stride length".But everyone is just scratching their heads, or...doesn't know the scientific meaning behind these words.

"Let's take a look at these two knowledge points first. The basic knowledge must be memorized. If you really can't remember it, you can take notes to assist your memory." After speaking, Su Shen wrote down two knowledge points on the small blackboard——

First, the biomechanical principles of sprint arm swing.

Second, the exercise physiology principle of sprint arm swing.

Third, the sports psychology connection of sprint arm swing.

After speaking, everyone also entered the state. After so long, everyone has gradually become used to Su Shen giving lectures to everyone from time to time, talking about these basic principles that they usually don't study or take the initiative to delve into.To be honest, everyone was somewhat resistant at first, even Zhao Haohuan didn't know that they were running, and they didn't study running, so what are they doing?

But it is the same as the impact on your movement cognition after you figure out the distribution of muscles and bones.

For the entire sprint movement and practice, your subconscious mind will respond more clearly and intuitively.

This is not just about learning sports knowledge. It is of great benefit to how you control a certain joint, a certain part of your muscle, and a certain muscle during exercise.Otherwise it is...

I only know how to run around with my eyes closed, and I don't know how to use force, and I don't know where the main force is.

Invisibly, this is the least efficient training method.

For example, at the start-up stage, you haven’t learned these things, and you haven’t memorized these muscle distributions. How do you know that the two-layer muscle system is the main driver?The first layer is the gluteus maximus, vastus medialis, and biceps femoris, and the second layer is the vastus externus, gastrocnemius, semitendinosus, and rectus femoris?Even if you know the names of these muscles, ask yourself, except for the gluteus maximus, do you really know the rest, the rest of the structure, where in your body?

Only when you memorize, know, understand, and understand, can you be more clear about which muscles are most efficient in exerting force when starting.For the rest, you can reduce exertion and consumption, and achieve the effect of targeted training and improvement.

In this way, it will naturally get twice the result with half the effort.

……

"The principle of motion biomechanics of sprint arm swing - the swing of the arm is a periodic circular motion in which the forearm and upper arm rotate back and forth around the axis of the shoulder joint. The law it obeys in this respect is the law of conservation of angular momentum. For example, angular acceleration, rotation Inertia and combined external moment are all important influences..."

"The exercise physiology principle of arm swing in sprinting - during sprinting, the frequency of arm swing is high and the amplitude is large. In this way, muscles will continuously produce a large amount of lactic acid accumulation under anaerobic conditions, and lactic acid accumulation will lead to muscle fatigue. And Muscles are in a fatigued state of tension and contraction for a long time, which will cause muscle tension problems at the same time. At the same time, the tension of the passive muscles will involve the normal contraction speed of the prime mover muscles. At this time, due to the long-term tense contraction of the muscles, Compressing the blood vessels and nerves in the muscles, accelerating the resistance of blood flow, etc., will cause premature fatigue of the arm muscles..."

"Sports psychological analysis of sprinting—…For example, if a natural and reasonable arm swing technique is used during a race, science has proved that this has a significant effect on reducing the psychological burden. From the perspective of learning, it is in line with the sports psychology of running forward. For example, if the active arm swing technique is used, the driver will not be psychologically prone to active relaxation like legs, worrying about his own speed decline and frequent psychological anxiety Status and so on..."

"Then here comes the problem."

"Do you know what the arm swing method of the traditional department in our country is like?"

Faced with Su Shen's question, most people can only make gestures below, but if you really ask them to say it, they really can't say one, two, three.

This is the result of the lack of scientific sports research.

It will become only knowing how to bury your head and practice hard, only knowing to rely on muscle memory to force learning, but lacking subjective understanding and assistance.

Comparing with others who have a thorough understanding and then use it, it will definitely get twice the result with half the effort.

Seeing the repeated shaking of the head below, Su Shen immediately wrote a series of words on the small blackboard:

"The traditional arm swing is to exert force from the shoulder, bend the elbow joint, and force forward and backward. With the force of the shoulder joint as the core, it forms a pendulum swing forward and backward." Su Shen also made an arm swing movement on the spot, just below The one I always do.

"In this way of swinging the arm, the angle of the elbow joint is about 60~70 degrees. At this time, we can find that in the process of swinging the arm forward and backward, due to the effect of inertia, habits and the influence of the structure of the shoulder joint , there will be two negative limit high points." Su Shen stopped and made a demonstration, then pointed to two places on his arm, and continued: "Did you see that at these two high points, our arm The swinging motion, here, here, there will be a brief pause."

Su Shen asked the following people to try it themselves: "Then the problem is here, do you feel it? These two negative limit high points, this pause action, will directly affect the continuity of the arm swing. Once the continuity is affected, then The arm swing speed will naturally also be affected, which will produce a chain reaction, affect other sprinting movements, and finally cause the destruction of the entire coherence, naturalness, and coordination. In this way, it will not affect the final sprint performance."

"I, I'll go, it seems true."

"When you say that, you really feel this way."

"I used to think it was my physical joint problem. I asked the coach, and the coach said it's not a big deal, just standardize it. It turned out to be this problem. There are two negative limit high points, which limit our arm swing activities."

"I thought I thought... that's how the professional team swings their arms, that's what it feels like."

In an instant, God Su ignited the discussion below.

Sometimes it is like this, just throw out an introduction, and then lead everyone in that direction, everyone will slowly wake up and react slowly.

Even some coaches sat down unknowingly and listened attentively to the knowledge Su Shen said.

Because now in the team, Su Shen is the treasure of the team.

Who dares to say no?
At the beginning, it might be a little embarrassing to be "educated" by a young man, but they finally found out...

As long as your own "face" passes.

Well, everything is different.

The mountains are better, the water is better, and the steamed buns in hand are also fragrant.

After learning this, it will be a great capital and benefit for them to work in other places in the future.

After figuring out these joints, who will come out and sing against Su Shen in the Guangdong Provincial Team now?

I'm afraid I'm holding a small book and carrying a small bench, for fear that I will miss Su Shen's "Frontier Sports Knowledge and Science Lecture".

……

"Then let's see now, how can we improve this situation?" After Su Shen finished speaking, he made a demonstration in front of him, using his shoulders as the axis instead of just using his shoulders to exert force, so as to swing his arms action.

And this action, no matter how you look at it, looks like... drawing a circle.

"Xiao Tian, ​​your shoulders seem to be exerting strength, and it seems that you are not exerting strength. What exactly is it, I am a little hard to say." Hu Kai is also a domestic elite in this field, and he quickly made a judgment, but also Can't explain clearly.

"That's right, what Brother Kai said is basically on point, but it's almost there. Let's see, these two exercise methods, first of all, the role of the shoulders has changed. The previous one is full force, using force to drive the shoulders, elbows The joints flex and force forward and backward, creating a pendulum swing back and forth."

"The one I'm talking about now is called a circular swing arm."

"Using the shoulder joint as the axis, it swings backward and upward at an angle of 80 degrees to 60 degrees at the elbow joint."

"That's it." Su Shen said while doing a demonstration: "Then swing back and up until the upper arm and the body form an angle of about 90 degrees, and then make a circular arm swing up and down through the back."

"Xiao Tian, ​​do it again, let's see." Zhao Haohuan and the others had already become interested, and suddenly turned into Teletubbies, each of them repeated the sentence again and again.

"Look good everyone, here is the difference. First of all, the angle has changed. The angle of the elbow joint of this circular swing arm is about 60 to 80 degrees, instead of the previous 60 to 70 degrees. Secondly, if you want to add Large step length and stride frequency, this technique can help you, just need to increase the angle of the elbow joint when swinging forward."

"Especially the type of stride." Su Shen looked at it and said with a smile: "This is good news for you. If you want to increase the stride length and modify the stride base in the future, the arm swing mode with circular swing arms is your first choice. This is because the traditional arm swing can take into account the stride frequency, but... because of this arm swing mode, it cannot solve the problem of arm pause when the arm swings to the front and rear high points, so it Limits the stride improvement advantage."

"So that's the case! I said why it's so difficult for me to modify the stride length, and it's not comfortable at all. On the contrary, it's much more comfortable to modify the stride frequency. So the problem is here!!!"

"It's too cheating! It's too cheating! How many wrong paths have been taken!!!"

The following one after another "howling" continuously, it can be seen that even these elite athletes of the same generation in domestic sprinting are also "victims" in this regard.

"Of course, this can also be used to better optimize the stride frequency." Su Shen continued: "Because the back swing and the front swing of the circular arm swing form a closed circular shape, which is equivalent to effectively solving the problems in the arm swing movement. , the pause problem when reaching the front and rear high points. Solving this pause problem naturally equals to speeding up the swing frequency of the swing arm, so as to optimize and increase the stride frequency."

"At the same time, because the movement method of the circular swing arm itself has the best swing inertia, it is equivalent to using the motion inertia, and the direction of its swing is also required to be consistent with the direction of running. In this way, the swing The penetrating force generated during the arm swing will not produce force component effects. This has a very positive promotion significance for increasing speed, saving energy, and making better use of the biomechanical characteristics of the swing arm."

"However, although this circular arm swing is useful and has many advantages, there are also problems that cannot be ignored." Su Shen said: "Everyone must remember this problem clearly, so as not to cause irreversible injuries during training and affect the results. and training."

Su Shen drew a structural diagram near the shoulder joint on the small blackboard, and said: "Because this technique places a heavy load on the shoulders, the whole needs to use the shoulders as the axis to drive, so it may require more force than simply using the shoulders." More functions. In this case, the items that we must do at the same time in our daily training are———”

"Relaxation, stretching and traction of the muscles near the shoulders, as well as the improvement of shoulder flexibility, shoulder support, and shoulder strength. This part of the shoulder is also called the 'core part' of the upper body. If this part is injured, you You probably won’t be able to do anything with your upper body.”

"So, I have a set of shoulder training, improvement, resistance, flexibility and other training here, and I will send it to everyone later. Everyone should remember to intersperse it in daily training, improve it bit by bit, and lay the foundation for subsequent technical improvements. ,prepare for."

After Su Shen finished speaking, he put down the chalk, looked up at the domestic elite athletes who had "learned out of school", and asked——

"Do you understand everything? If you haven't learned and understood, you can bring it up again. I will explain what you don't understand in detail."

Each of the following is the feeling that the brain has been hollowed out.

For them, it is really not an easy task to accept such profound theoretical knowledge.

It's not a problem of learning ability and IQ, it's just that they don't have the habit of learning the theory, so they suddenly learn it, and it's so esoteric at first, and they will naturally feel a little "unsuitable".

For this situation, what is God Su's solution?

Not quite used to it, not quite used to it, right?
Hey, it's ok.

Then learn more, memorize more, take more exams, learn how you adapt, learn how you get used to it, isn't it all right?

Crowd: ...

"By the way, it's still the same, memorize it in a short time, and then I will spot check one by one. Those who can't memorize it, don't learn this new technology. Let's talk after memorizing it."

Ahhhhh!

God, earth, please let Mr. Su be a person.

We really hate "endorsement".

"You hate endorsements, don't you? Do you want to write another thousand-character post-reading review?"

Everyone heard that Su Shen's thinking was so "Russian", so he hurriedly chose the former.

Just kidding, memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize memorize words

But they don't know that after this period of training, their sports science concepts and sports-related knowledge have been imperceptibly surpassed by a large portion of the rest of the domestic athletes.

If you want to improve, you must first endorse.

It has also become one of the most talked-about interesting stories of the "Su God Line".

The degree of familiarity with the outside world is comparable to the question of the century - "What is the size of Su Shen's butt".

tied first.

PS: Every time I write a technical improvement, I will be bald, hahahaha, laughing and crying.

It is too difficult to sum up the difference between the traditional department and the latest technology, Xiaozi is so bald, everyone hurry up to comfort Xiaozi's injured and young heart.woo woo woo.

I can't do it today, I squeezed it dry, woo woo woo~~~
