Chapter 337 Thumb thump thump ~ Xia Xuns new technology has arrived!
Ersha Island.
Guangdong Provincial Track and Field Team.
Su Shen has made a summer training plan and is also preparing for the Hong Kong competition 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 Sutsugo Shingo that this small game suddenly attracted much attention.
But now, unlike a decade or so later, it is still an era when Japan absolutely dominates the Asian sprint world.
Therefore, even if Guozihao says that he must be upright and never give up, it will only make everyone applaud Guozihao's courage, and few people really think that they can win.
However, it is also this external environment that allows everyone to prepare for war under a more low-pressure public opinion.
According to the rules, there was no point in attending so many people. In order to ensure the victory of this battle, Yuan Guoqiang came up with a plan——
The three giants Su Shen, Zhao Haohuan and Hu Kai accepted the appointment.
The rest can just stay at the training base and train.
This is a very correct decision, because there is no need to go there, of course...
Because the place in Guangdong Province is very close to the other side, if you complete the procedures, you can even leave on the same day without any trouble.
Xiangjiang Xiangjiang is actually just across the river from here.
For people here in Guangdong Province, it is not that far.
Su Shen continued to give everyone "classes", not only basic training classes, resistance training to improve strength and physical fitness, but also technical improvements. Especially Zhao Haohuan and Hu Kai, they have to make sexual adjustments. Taking advantage of this period
After a relatively long time and a relatively complete process, Su Shen began to put forward the areas he had always wanted to improve, that is————
Improved arm swing.
During the winter training, I had to modify my hips, so I didn’t have time to modify this aspect.
It's better now, and the summer training time is relatively complete. Except for one competition, everyone didn't play many games.
This is exactly what can be done to improve this aspect.
How to improve the swing arm?
There are also different opinions in this country, but as someone who has experienced it, Su Shen knows very well what the future trend will be——
Circular arm swing action.
Yes, this is the latest direction of future swing arm technology research.
This system was only started to be studied and published in China around 2015, which is almost ten years from now.
In ten years, it was almost the peak years of a generation or even two generations of sprinters.
Therefore, it must be equipped.
…
"Arm swing? Is there something wrong with our current arm swing?" A group of people were also confused. They didn't know what Su Shen meant by this. The most important thing about arm swing is the specifications, strength and frequency, and even the angle.
It’s the end, what else can be done?
This also needs to be changed?
This statement, however, is completely wrong.
The quality of your arm swing technique is crucial to improving your performance.
"We all know that the effect of arm swing is to maintain balance. The faster the arm swings, the stronger the ability to drive the lower body. But do you know why arm swing has these effects? In addition to these, what other effects are there? Or rather
, what else can be improved?”
Everyone was confused, and some people put forward some sporadic arguments, such as "increasing speed", "increasing cadence", "increasing stride length" and so on. But everyone was just scratching the surface, or... at all
I don’t know what scientific meaning these words represent.
"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 two knowledge points on the small blackboard -
First, the biomechanical principles of sprint arm swing.
Second, the principles of exercise physiology of sprinting arm swing.
Third, the sports psychology connection of sprint arm swing.
After that, everyone got into the mood. After so long, everyone has gradually become accustomed to Su Shen giving everyone lectures from time to time, explaining these basic principles that they usually would not study at all or take the initiative to delve into. To be honest, at the beginning,
Everyone was a little resistant. Even Zhao Haohuan didn't know that they were running and not studying running. What were they doing?
But it will have the same impact on your motor cognition after you figure out the distribution of muscles and bones.
For the entire sprint movement and practice, your brain will subconsciously react more clearly and intuitively.
This is not just about learning sports knowledge, it is also of great benefit to how you control certain joints, parts, and muscles during exercise. Otherwise...
I only know how to run blindly with my eyes closed, and I don’t know how to use force or where to use force mainly.
This is virtually the most inefficient way of training.
For example, in the startup stage, if you have not learned these things and memorized these muscle distributions, how do you know that it is the main driver of the two-layer muscle system? The first layer is the gluteus maximus, vastus medius, and biceps femoris, and the second layer
Is it the vastus lateralis, gastrocnemius, semitendinosus, or rectus femoris? Even if you know the names of these muscles, ask yourself, do you really know other places and other structures in your body except the gluteus maximus?
Location?
Only by memorizing it, knowing it, understanding it, and understanding it, can we have a clearer understanding of which of these muscles are the most efficient at exerting force when activated. The remaining parts can be used to reduce force exertion and consumption, and to be more targeted.
The effects of training and improvement.
In this way, you will naturally get twice the result with half the effort.
…
"The biomechanical principle of the arm swing in sprinting - the arm swing is a periodic circular motion in which the forearm and upper arm rotate back and forth around the shoulder joint axis. The law it obeys in this regard is the law of conservation of angular momentum. For example, angular acceleration, rotation
Inertia and total external force moment are all important influences..."
"The exercise physiology principle of sprinting arm swing - during sprinting, the arm swings with high frequency and large amplitude. As a result, the muscles will continue to produce a large amount of lactic acid accumulation under anaerobic conditions, and lactic acid accumulation will lead to muscle fatigue.
Muscles that are in a fatigued state of tense contraction for a long time will also cause muscle relaxation problems. At the same time, the tension of the passive muscles will affect 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 blood flow resistance, etc. will cause premature fatigue of the arm muscles..."
This chapter is not over, please click on the next page to continue reading! "Psychological analysis of sprinting -...For example, if you use natural and reasonable arm swing techniques during competition, science has proven that this has a significant effect on reducing the psychological burden.
For example, using forward acceleration and forceful arm swinging to drive, from a psychological point of view, is consistent with the sports psychology of running forward. For example, using active arm swinging and relaxation technology, the driver will not easily produce leg-like movements psychologically.
Take the initiative to relax, worry about the frequent psychological anxiety caused by slowing down, etc..."
"Then here's the problem."
"Do you know what our country's traditional arm swinging method is like?"
Faced with Su Shen's question, most people can only make gestures below, but if you really ask them to tell you, they really can't tell you one, two, three.
This is the result of the lack of scientific research on sports.
It will become that they only know how to practice hard and rely on muscle memory to learn forcibly, but they lack subjective understanding and assistance.
If you understand it thoroughly before applying it compared to others, you will definitely get twice the result with half the effort.
Seeing the following people shaking their heads, Su Shen immediately wrote a series of words on the small blackboard:
"The traditional arm swing is exerted by the shoulder, the elbow joint is bent, and the force is exerted forward and backward, with the force of the shoulder joint as the core, forming a front and back pendulum-like swing." Su Shen also made an arm swing motion in place, which is just below
The one I usually do.
"In this way of swinging the arm, the angle of the elbow joint is about 60 to 70 degrees. At this time, we can find that when the arm swings forward and backward, it is affected by inertia, habits and the structure of the shoulder joint.
, there will be two negative limit high points." Su Shen stopped and gave a demonstration, then pointed at two places on his arm, and continued: "Have you seen it, at these two high points, our arms
The swinging motion, here, here, there will be a brief pause."
Su Shen asked the people below 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 be affected, which will cause a chain reaction, affecting other aspects of sprinting, and ultimately causing the destruction of the entire coherence, naturalness, and coordination. In this way, it would be strange if it does not affect the final sprint performance."
"I-I'll go, it seems real."
"When you put it like that, it really feels like this."
"I used to think it was a problem with my physiological joints. I asked the coach, and the coach said it was not a big deal, just standardize it. It turned out to be this problem. There were two negative limit high points, which restricted our arm swing activities."
"I thought... the arm swing of the professional team originally felt like this."
In an instant, Su Shen ignited the following discussion.
Sometimes it's like this, you just need to throw out an introduction and lead everyone in that direction, and everyone will slowly wake up and react.
Even some coaches sat over unconsciously and listened intently to what Su Shen said.
Because now in the team, Su Shen is the team's treasure.
Who dares to say no?
At first, being "educated" by a young man might have been a bit embarrassing, but in the end they discovered...
As long as one's own "face" is over.
Well, everything is different.
The mountains are getting better, the water is getting better, and the steamed buns on your hands are getting better.
Learning these things well will be a great asset and benefit for them to work elsewhere in the future.
After figuring out these joints, who will come out to play against Su Shen in the Guangdong team?
I was holding a small notebook and carrying a small bench, and I was afraid that I would miss Su Shen's "Lecture on Cutting-Edge Sports Knowledge and Science".
…
"Then let's see now, how to improve this situation?" After Su Shen finished speaking, he personally gave a demonstration in front of him, using his own shoulders as the axis, not just the shoulders to exert force, to swing his arms.
action.
And this action looks like... drawing a circle.
"Xiao Tian, your shoulder seems to be exerting force, but it seems that it is not exerting force. What it is, I can't tell." Hu Kai is also a domestic elite in this field. He quickly made a judgment, but also
I can't explain it clearly.
"Yes, Brother Kai has basically hit the point, but he's still not close. Take a look at these two methods of exercise. First, the role of the shoulders has changed. The former one uses full force to drive the shoulders and elbows.
The joints are bent and forced forward and backward, forming a pendulum-like swing forward and backward."
"The one I'm talking about now is called a circular swing arm."
"It takes the shoulder joint as the axis and swings back and up at an angle of 80 to 60 degrees at the elbow joint."
"That's it." Su Shen said while demonstrating: "Then swing it back and up until the upper arm and the body form an angle of approximately 90 degrees, and then make a circular arm swinging motion from back to top, forward and down."
"Xiao Tian, do it again, let's see." Zhao Haohuan and others were already interested, and they immediately turned into Teletubbies, repeating one sentence over and over again.
"Look, 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
With long stride length and cadence, this technical movement can help you. You just need to increase the angle of the elbow joint appropriately when swinging forward."
"Especially for players with stride length." 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 circular arm swing mode will be your first choice.
.This is because the traditional swing arm can take into account the cadence very well, but...because of this arm swing mode, it cannot well solve the problem of the arm stopping when the arm swings to the two high points at the front and rear, so it
Limits the improvement advantage of stride length.”
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "So that's it! I said it was so difficult for me to change the stride length and it was so uncomfortable. On the contrary, it was much more comfortable to change the stride frequency. It turns out that the problem is
it's here!!!"
"It's so deceptive! It's so deceptive! What a waste of time it has been!!!"
The following people are "howling" incessantly. It can be seen that even these elite sprint athletes of the same generation in China are also "victims" in this regard. Not only wasted time, but their efforts were also in the wrong direction.
"Of course, you can also use this to better optimize the stride frequency." Su Shen continued: "Because the circular arm swing movement, the back swing and the front swing form a closed circle, which effectively solves the problem in the arm swing movement.
, the pause problem when reaching the front and rear high points. Solving this pause problem will naturally speed up the swing frequency of the swing arm, thereby optimizing and increasing the cadence."
"At the same time, because the circular swing arm has the best swing inertia, it is equivalent to using the motion inertia. In addition, the swing direction must be consistent with the running direction. In this way, the swing arm has the best swing inertia.
The penetration force generated during the arm movement will not produce component force effects. This has a very positive significance in improving speed, saving physical energy, and making better use of the biomechanical characteristics of the arm swing."
"However, although this circular arm swing movement is easy to use and has many advantages, there are also problems that cannot be ignored." Su Shen said: "Everyone must remember this issue clearly to avoid irreversible injuries during training and affect performance.
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 entire body needs to be driven by the shoulders, so it may require more effort than simply using the shoulders to exert force.
It has more functions. In this case, the items we must do at the same time in our daily training are——————”
"Relaxation, stretching and traction of the muscles near the shoulder, as well as improvement of shoulder flexibility, shoulder support, and shoulder strength. The shoulder is also called the 'core part' of the upper body. If this place is injured, you
It’s very likely that I won’t be able to do anything with my upper body.”
"So, I have a set of shoulder training, improvement, resistance, flexibility and other training, which will be sent to you later. You should remember to intersperse it in your daily training and improve it bit by bit to 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 below who had "lost their studies", and asked -
"Do you understand everything? If you haven't learned it yet or don't understand it, you can ask it again and I will explain it in detail to you if you don't understand it."
Everyone below feels like their brains have been hollowed out.
It is not easy for them to accept such profound theoretical knowledge.
It’s not a matter of learning ability or IQ, it’s just that they usually don’t have the habit of learning theories, so when they suddenly learn something so profound, they naturally feel a little “unfit”.
What is Su Shen's approach to this situation?
Not quite used to it, right?
Hehe, it's okay.
Wouldn’t it be enough to study more, memorize more, and take more tests, so that you can adapt to it and get used to it?
Everyone:......
"By the way, it's still the same. Memorize it in a short time, and then I will randomly check it one by one. Those who can't memorize it should not learn this new technology. We will talk about it after memorizing it."
Ahhhhh!
Heaven, earth, please let Teacher Su be a human being.
We really hate "endorsement".
"You hate endorsements, don't you? Then how about writing another thousand-word review?"
When everyone heard that Su Shen's idea was so "Russian", they quickly chose the former.
Just kidding, just endorse and recite and write again and again, that is really not what humans do.
But they don't know that after this period of polishing, their sports science concepts and sports-related knowledge have subtly surpassed the rest of the domestic athletes by a large margin.
If you want to improve, endorse it first.
It has also become one of the most talked about interesting stories of the era in the "Su Shen family".
The degree of familiarity to the outside world is comparable to the question of the century - "What is the size of Su Shen's butt?"
Tied for first place.
PS: Every time I write about technical improvements, I become bald, hahahaha, I laugh and cry.
It’s really difficult to summarize the differences between traditional technology and the latest technology. Xiao Zi is so bald, so please come and comfort Xiao Zi’s injured and young heart. Woo hoo hoo.
I can’t do it today, I’ve squeezed it dry, wuwuwu~~~
