Chapter 507 Su Shen overthrows traditional classics again
After winning the Golden Runway Award, Su Shen and the others received a Florist Lawrence Award two days later.
Zhao Haohuan and Su Shen both got it.
Then each of them went back home, gathered with relatives and friends at home, and then returned to Ersha Island to start the official winter training.
There are many things to do in this winter training.
And the details have changed a lot.
Maybe the entire athletic performance pyramid needs to be dismantled again.
We still have to catch up with the time for next year's competition, which is actually very tight.
And with everyone running a series of good results in 2006, the era of worrying about the A mark has long been a thing of the past. By then, in order to compete for a spot in the World Championships, I will probably have to break my head.
Everyone knows that this trial may be the most brutal one since the establishment of the Flower Planter Dash Team.
There are three A-mark quotas in total, see if you can get one.
This competition is probably going to be a situation where a group of people are surrounding the three spots and killing each other randomly.
But this kind of happy worry definitely makes Yuan Guoqiang and the others happy.
After all, this kind of thing has happened before.
It used to be a headache to get a B bid, but now it's better. There are so many A bids, but it just depends on who gets it.
Yuan Guoqiang also made it known before the winter training. It is absolutely fair. Whoever wins the trial will be admitted. There is absolutely no ambiguity.
There is no malpractice for personal gain at all, it is an internal operation.
In this case, everyone theoretically has hope.
This also made Ersha Island suddenly full of fighting spirit and enthusiasm.
The improvement of physical fitness needs to be continued, but the deepening reform of technology must also begin.
This kind of reform will be much bigger than the previous Asian Games training camp.
Even in the beginning, your entire "performance pyramid" will be destroyed.
The performance will drop significantly. Su Shen remembers that when he made the biggest technical change, even the female team members of the United States could not run. At one time, he wanted to give up running and go home. This is the risk of technical changes.
Especially if you don't know whether this technical reform is good or bad, not many people dare to do it.
But one good thing about Su Shen is that he definitely knows whether this is good or not.
This allows him to help everyone save the cost of trial and error and directly use the most scientific and effective method to make progress.
The first thing that needs to be changed is that the entire floor-scraping technique was not allowed by his previous physical fitness and time. He had to do too many things. It is only now that he has the opportunity to completely carry out a technical reform of the floor-scraping technique.
The current land grabbing situation in China is a mixed mess.
Before the "hip extension technique" of Su Shen was unified in China, they were almost the same, with no difference.
There are all kinds of theories and experiences, including half-knowledge, quotes taken out of context, and so on.
And you have to know that groundbreaking is one of the most important techniques in professional sprinting.
If this is not done well, it will naturally become a mess.
If the technical level cannot be improved, the performance limit will certainly not be improved.
Su Shen had already communicated this with Randy and the others in advance. When Randy first listened, he almost wanted to make Su Shen his "confidant".
Because he couldn't say anything in Han Country, he didn't expect that when he came here, there would be people here who had exactly the same opinions as him.
And the more they chatted, the more he discovered that Su Shen's understanding was quite deep, even... sometimes further than he thought.
The key is that before the Asian Games, Su Shen also compiled a "comprehensive summary of the evolution and genres of ground-grabbing techniques" in China and gave it to Randy and the others. This was a big help to Randy. After all, he was also an outsider and had many things.
Not knowing enough, with Su Shen's "Comprehensive Summary of the Evolution of Gripping Techniques and Schools", Randy and Su Shen promised that they would finish it before winter training, then redesign it and come up with a winter training plan.
Su Shen naturally believes in Randy's experience and ability. Isn't this...
Now Randy is explaining these things above, and then he must bring Su Shen over to explain them with him.
In their eyes, Su Shen is now an industry research leader who is equal to them.
This was the result of Su Shen's papers and experience gradually conquering them.
Otherwise, these two people are actually arrogant in their hearts.
They are all international masters. How could they discuss this with a 17-year-old boy if they are not convinced?
In fact, both Ning Dehai and Yuan Guoqiang discovered this, and they could only be shocked in their hearts...
This guy Su Shen is a bit too fierce.
Even if they conquer the country, Yuan Guoqiang and others also know what the level of the country is, but...
The few people in front of them are international bigwigs, all experts with various senior qualifications and knowledge levels. Why do they act like...discussing with Su Shen in front of him, and even sometimes go to him to ask questions?
??
Yuan Guoqiang asked Ning Dehai, who shrugged and replied: "Anyway, when I met Su Shen, people were like this. There was nothing about track and field that they didn't understand. It was an encyclopedia."
"What a ghost. How did you grow such a brain?" Yuan Guoqiang shook his head and said: "If this was not happening in our flower gardening family, but in other countries in Asia, it would be really disappointing."
"Director Yuan, why are you thinking so much? Xiao Tian is a member of our flower gardening family in this life, and maybe he was also in the previous life."
"That's right. It must have been the same in the last life." Yuan Guoqiang nodded and smiled.
…
"The action structure of sprinting technology has changed from 'extend the knees and push the ground' to 'extend the hips and swing high to the ground.' Since the action structure has been changed, the technical movements involved, the muscle force of various parts of the body, and the way bone levers work have also changed.
Corresponding changes will definitely occur. For example, 'extending the knees and pushing on the floor' emphasizes the development of the quadriceps in the front thigh group and the triceps in the back of the calf, while 'extending the hips and squatting high' emphasizes the development of the waist, hips, buttocks and thighs.
The muscle groups at the roots are regarded as the biggest source of power. It emphasizes the use of muscle strength in the center of the body to drive the development of muscle strength in other parts of the body. This change in the action structure is guided by the overall speed and rhythm structure to improve the overall running speed.
Speed is the goal..."
This chapter is not over yet, please click on the next page to continue reading! "The latter has been comprehensively deepened internationally. Now let me talk about a few points to pay attention to."
"The first point no longer emphasizes fully straightening the knee joint, but regards the high swing of the legs around the axis, extending the hips, as a key link in sprinting technology. In our country, we used to pay too much attention to the Soviet style and Japanese style of fully straightening the knee joint.
This may have been an advanced approach in the last century, but after the 21st century, it has lagged behind the times."
"The second point, 'Extend the hips and swing high to the floor,' puts more emphasis on the dominant role of the muscles around the waist and hips. Especially the gluteus maximus, which is commonly known as the buttocks."
After Su Shen said this, he smiled, because now everyone knows that in the entire track and field team, Su Shen's butt is very good.
Almost no one can compare.
Having a large hip muscle ratio is actually a kind of talent.
The distribution of muscles is not the same for everyone.
Some people can hang more muscle in this part of the body, while others can't under the same conditions.
This talent is actually one of Su Shen's hidden talents.
"The third point is that modern sprinting requires athletes to use the strength of the muscles in the center of the body to drive the strength of other parts of the body. This clarifies the key link in improving sprinting technology and the main direction of developing sprinting fast strength, which is different from the previous
It will be completely different.”
…
"So how to operate it specifically?" Su Shen showed the mechanical structure diagram drawn by Ralph Mann and said: "Here we need to understand the mechanical principles first. According to the principles of sports mechanics, sprinting is a combination of support and
If the human body is regarded as a particle in the movement of an object, the periodic motion of alternating soaring in the air is a horizontal displacement motion. But..."
"But in fact, the human body's horizontal displacement is not a simple horizontal displacement movement of pointing, but a curved movement with multiple centers, multiple radii, and different operating radians. This is what is shown in this picture." Su Shen held it.
The little black stick pointed at a certain spot on the whiteboard and said: "To be specific, it is - a curved movement with the hip joint as the center of the circle and the thigh as the radius."
"A curved movement with the knee joint as the center of the circle and the calf as the radius."
"A curved movement with the ankle joint as the center of the circle and the sole of the foot as the radius."
"And the curved motion with the shoulder and elbow joints as the center of the circle and the upper arm and forearm as the radius."
"The horizontal displacement of the human body is precisely through these curved movements with multiple centers, multiple radii, and different operating arcs. Under a certain space-time configuration, muscle contraction is used as the driving force, and the interaction and coordination are coordinated. The ground and human bone levers are used as force transmission media.
Realized in the decomposition and synthesis of force..."
"Then here comes the key question." Su Shen transformed into "Professor Su State", looked down, and said: "Since the human body is performing horizontal displacement with the technical movements of running, the center of gravity of the human body and the ground that serves as the support are not in the same position.
On the same level. Then many previous technical movements and technical theories will be overturned. Under the latest scientific system, whether it is the force exerted by the human body's motion device on the ground or the support reaction force fed back to the human body by the ground, it can
...decomposed into vertical component and horizontal component."
"It is naturally wrong to place too much emphasis on fully straightening the knee joint." Su Shen said: "So everyone must remember that in the latest biomechanical system, there are only horizontal components that are consistent with the direction of human body movement. This is
What really drives human displacement.”
"In that case, has anyone found any problems with our country's original ground-stripping technology?" Su Shen asked.
After a silence, Zhao Haohuan suddenly spoke, but his tone was not very sure, and said: "So the problem is on the toes? Is that right? Xiaotian?"
Su Shen's eyes lit up and he nodded in encouragement, as if Zhao Haohuan was really a good student, and said: "That's right. It's on the toes."
"What Gou Huan said is right and accurate. This is exactly what Coach Randy and I are going to say next." Su Shen said: "Traditional toe running is completely...wrong. This is the biggest problem for everyone in winter training.
One of the issues is comprehensive reform of land acquisition methods.”
Yuan Guoqiang listened from behind and only glanced at Ning Dehai beside him...
Look, our genius disciple has overturned the classics and traditions again.
But after several previous experiences, Yuan Guoqiang also felt...
It seems that I am not so shocked and unable to accept it.
Anyway, it's not the first time, right?
People have to adapt to the rhythm.
Those who cannot adapt will be left behind by the times.
Yuan Guoqiang did not want to "retire and fish" so early.
Therefore, we must keep up.
PS: Technical adjustments are really difficult to write. There are too many papers to check, so it will be a little slower, o(╥﹏╥)o~~~
Who told Xiao Zi to go to the "point of no return" in the technical field? What she chose, she had to finish with tears.
