Chapter 911 What is professional? This is called professional
During winter training on Ersha Island.
Just as Liu Xiang began the arduous rehabilitation process, the rest of the people also began their own daily practice.
The current echelons are clearly divided.
Su Shen and Zhao Haohuan are in the first echelon. They are the training methods of the Ten Breakers. In fact, Su Shen and Zhao Haohuan are even different.
The further you go, the greater the differentiation, the greater the personalization, and the lower the homogeneity.
What Wen Yongyi needs to strengthen this time is mainly his core and ground grabbing skills. Because under the analysis of the "Champion Model" system, Wen Yongyi's late game dropped so fast that he was almost on the same level as player Joanna.
It is because he has major problems in these two aspects, so this winter training mainly focuses on this area.
But at this level, it really depends on the individual’s practice. I’m not saying I’ll point it out to you and you can do it.
The specific matter still depends on Wen Yongyi himself.
Hu Kai wants to strengthen his overall ability. After all, his technical system has been established for a long time, and he cannot keep improving many techniques. For example, the so-called arc-shaped ground scraping, Hu Kai has a lot of troubles when he really does it.
Mistakes.
Just like what Randy is analyzing for him now————
"Lake, through the latest Casio EX-FH20, shooting frequency 210 Hz, shutter speed 1/1000 s, shooting range 5 m, shooting distance 15 m, the main optical axis of the camera is perpendicular to the running direction, using Ariel 2016 Staion to record the video
Analyze the video, use 16 joint points to calculate the center of mass of the human body, use 14 hz digital filtering to smooth the original data, and obtain the data required for the research, it can be concluded————”
"Your starting position maintains the same ratio between the distance from the starting line to the front and rear footboards, but the distances between the front of the starting block and the rear footboards from the starting line are moved backwards by 0.05 m and 0.07m respectively; the preparation posture is forward and backward.
The leg, hip and knee angles have increased, the front and rear hip angle increments are 12. 8 and 22 respectively, and the front and rear knee angle increments are 30. 3 and 17. 2 respectively, making the relative position of the trunk and lower limbs more stretched and reducing
It increases the stretching range of posterior group muscles such as gluteals and hamstrings, and reduces the tension of anterior hip flexor muscles such as rectus femoris and iliopsoas... We are ready to increase your preparation posture and trunk angle at the moment of kicking off.
, increase the knee angle at the moment of lifting off the ground, and try to make the adjustment without causing attenuation of the horizontal speed at the moment of pedaling off.”
"Secondly, your hip extension, knee extension, and toe flexion explosive force needs to be improved, and the power output needs to be increased. For example, your first step is only 4 m/s. This level of intensity is still too low. This is your
The reason is that there is a problem with the body’s comprehensive force-producing structure.”
"And your body's post-p potentiation, that is, the body's post-activation enhancement effect under multiple large loads and sub-maximal loads is not enough. This is where you need to make adjustments. If possible, it is recommended to reconstruct your exercise representation.
pyramid."
"There are also many problems with your floor-scraping technique. The curved movement with the hip joint as the center of the circle and the thigh as the radius, the knee joint as the center of the circle, the calf as the radius, the ankle joint as the center of the circle, and the sole of the foot as the radius.
The curvilinear motion of the radius and the curvilinear motion of the arm and the forearm with the shoulder and elbow joints as the center of the circle respectively. The horizontal displacement of the human body is exactly through these curvilinear motions with multiple centers and multiple radii and different operating arcs. You are also doing very poorly.
, at least under the analysis of electronic equipment, a lot of your work is useless and cumbersome. For example, when your feet touch the ground and transition to the back-pedaling stage through buffering, they should be pressing and stretching the hip, knee, and ankle joints in sequence.
Sequence. When extending the ankle joint, which is called ankle flexion in anatomy, you should try your best to extend the toe joint to reduce the back pedaling angle. However, when you do this, you do not exert force according to the best scientific order every time. We here
I call you the rigidity of technology. This is a problem that you have accumulated over time and has long been a habit in your body."
"Then your absolute speed and speed endurance development are also lacking. On the other hand, the distribution of speed and rhythm is unreasonable. The unreasonableness here is directly related to the premature transition to running on the way after accelerating from the start. Your pedaling and stretching
The acceleration section is too rapid, the support time is too short, and you cannot accumulate and obtain a larger momentum in a short period of time; this will further hinder your speed growth. In addition, you lift your trunk prematurely and your lower limbs lose the calf angle prematurely.
It is also the main manifestation of ending acceleration early. This will greatly reduce your forwardness. Look at the forward nature of your entire body. Except for the acceleration range, does it start to move more and more backward?
?That's a key sticking point."
"Another example is when you push your hip during a run, causing the pelvis on one side of the swinging leg to internally rotate, which makes the backstroke of the supporting leg's hip not strong enough, and the speed and amplitude of backextension become faster. And when the supporting leg extends its hip, it causes
The speed and the inertia of the running speed during the journey also compress the time for the knee joint of the landing leg to make a concession... Now we can give you several methods and plans." Randy showed these clear data to Hu Kai.
, said: "The first is conservative adjustment. This means making adjustments without disturbing your body structure. The advantage of this is that it can ensure the lower limit of your exercise table and allow your body to adapt to this process more quickly.
The recovery speed after adjustment will be faster. But the disadvantage is that it is very likely that there will be no qualitative improvement after changing it over and over again. This is a very real problem. There is a high possibility that the result will fall short, and there is also a high possibility that it will take practice to practice.
Go and do all your hard work in vain."
"The second is to completely reconstruct your sports performance pyramid and disrupt the basic things. The benefits are obvious. You can return to a blank sheet of paper and write new things arbitrarily, including bad habits and some subconscious reasons for poor health.
The structure can also be disrupted, reorganized or even completely changed. In this way, you can have a better future and better possibilities for moving forward, but..." Randy paused and said: "You also know that things
It can’t all be smooth sailing.”

"The bad thing about this is..."
"You probably do."
"Pyramid reconstruction failed."
"And the structure after the reconstruction fails is that you have given up all your original things, and then... your strength may plummet."
"You could end your career completely."
"Coach, aren't you being too serious? Brother Kai has been running for so many years. He won't be gone all of a sudden." Zhou Bing said. But in exchange, Randy only had a more serious expression.
, said: "This is not a joke, Zhou, if you decide to reorganize, there will be a possibility that your reorganization will fail."
"And the experience of this kind of reorganization is not that common in history. There is a lack of experience to follow. Even if there is experience, failure may occur due to the particularity of each person." Randy reminded,
Said: "And I have to tell the truth."
"This probability."
"Probably not low."
"It depends on whether you can bear it."
As soon as these words came out, the whole audience fell silent, because they all knew that Randy was definitely not a person who let things go without hesitation. Although he still likes to joke, if I tell you seriously, it is not a joke. And it is such a big deal.
Obviously, Hu Kai needs to make his own decision, otherwise no one can help him bear the consequences in the future.
Hu Kai stared at this. He actually knew that he had a problem, but he never thought that the problem would be so big.
And Randy made this very clear.
It was so clear that it almost revealed the blood pores in his sports capillaries.
This is naked anatomy.
Although this is the only way to go,... as a party involved, Hu Kai is still trapped in his own struggle.
After a while, Hu Kai slowly said: "There is no other way. If we are conservative, what is the probability? If we choose to completely reconstruct, what is the probability? Can you give me a rough idea?"
"It's hard to say. Everyone's body structure is different, and everyone's reconstruction process is also different." Randy said: "Then what you need to think clearly is that there may be big problems. If you have to say it,
Conservatively speaking, the probability of failure is not high, but the probability of success is only 10% at most, and this 10% is still a small repair. But if you choose the second option, then I say the probability of failure is probably more than 80%, or even possible.
Higher. Because we ourselves have no confidence in predicting the probability. In fact, you are also the first person we reconstruct."
"To completely reconstruct an elite athlete like you and to improve again is actually something that goes against the will of heaven. To use a metaphor, it is... you are negotiating conditions with God and re-talking about not reincarnating.
, can the conditions be restructured?”
"But if it succeeds, it is possible to exceed the current limit, and even hit ten. It is not impossible."
"All in all, we can't help you make this kind of decision. You have to make your own choice. Lake."
"You can tell us after you think about it clearly."
call--------
Hu Kai took a breath and said after a while: "I understand, but I need a few days to think about it."
"Okay Hu, this decision is very important and may even determine the rest of your career. You should think about it carefully." After Randy finished speaking, he looked at Hu Kai and nodded before starting the next person's winter training.
Plan announced.
"Zhang." Randy clicked on Zhang Peimeng, who walked out and listened to Randy's announcement in public.
For Zhang Peimeng, this is actually a rare opportunity.
After all, before this, he was not the "core team member of Ersha Island" at all.
So he won't get so much detailed resource distribution and resource analysis.
Some people may think, why don't you analyze it? Everyone should analyze it. You, Ersha Island, are not very responsible.
But in fact, anyone with some social experience will know that everyone and any team have their own load limits.
It is simply impossible for you to hold everyone accountable. The consequence of micromanaging everything is that no one can be trained.
In the end, everyone will become a mass.
So the best way is to make a name for yourself first, and then you can legitimately get these opportunities.
When you get these opportunities, naturally no one will make irresponsible remarks.
Otherwise, the "unstable military morale" and "complaints" caused by this would probably be a huge problem.
Secondly, if you really know Zhang Peimeng, the resources he has received are already much higher than those in his original timeline.
Otherwise, he would not have been able to reach this level of 10.10 in the Olympics.
This is already very fast.
But this kind of core building and core analysis of Randy's team is indeed the first time for him.
He also began to listen carefully.
"Step length and stride frequency index are important indicators for measuring the technical rhythm of the whole process. Research shows that the step length and stride frequency index of excellent athletes should be above 1.24 and 8.28. You still need to strengthen this aspect. Emphasis on "elasticity and strength"
, training that pays attention to "whipping and pressing down, enhances power output, increases the extent of knee extension before landing, emphasizes rigid support, and increases the step length of the 7 steps before starting will have a promoting effect on improving the average step length. In this regard, future Su
I will introduce you to a new technology that belongs to you, which Su Tai created for you, and you can take a good look at it then."
Zhang Pei was stunned.
He had heard Su Shen say this before.
But how busy Su Shen is, he has clearly seen it on Ersha Island.
The entire Ersha Island seemed to have so many people and so many teams, but in fact, the final "backbone" was only this young man who was less than twenty years old. Therefore, he had never asked about this matter, not wanting to cause trouble to Su Shen.
did not expect……
This chapter is not finished yet, please click on the next page to continue reading the exciting content! I am actually ready.
Really let him.
There is an indescribable movement in my heart.
He nodded to Su Shen, having already expressed his emotions as best as he could.
"Judging from the current full step length and stride frequency index data, it is already relatively close to the top athletes in Asia, but there is still a slight gap in step length. This is why we need to continue to strengthen it in future training.
"Step length and stride frequency index are important indicators for measuring the technical rhythm of the whole process.

"Compare Gatling, who is about the same height as you, and you will know where your problem lies. Both your stride frequency and stride length are lacking. Although you are not required to reach Gatling's level, you still have a lot of potential.
There is room for growth. If you do it well, it is very likely that every 0.1 increase, you can increase your speed and upper limit by a lot."
Sun Haiping and Liu Xiang were listening here. Liu Xiang was doing some rehabilitation arranged by Ralph Mann. He also saw this session and everyone gathered together, so he came over out of curiosity.
Anyway, he is still "recovering from injury", so he can't be too anxious and it's okay to come over and have a look.
The key is that Ralph Mann also wants Liu Xiang and Sun Haiping to realize from their own hearts... what exactly is scientific training.
Why scientific training is the future.
As he listened, Liu Xiang felt that he couldn't understand it, or... he didn't understand it at first.
In addition to knowing the meaning of some basic track and field professional terms, he knew nothing about the specific analysis and various system links of the human body. He wanted to ask Sun Haiping next to him, but unexpectedly he saw... Sun Haiping
He was also in the same daze.
Although.
I don’t know how many times the master and apprentice have been in a daze in the past few days since they came here.
But now, it is indeed, clearly, that they have this expression and demeanor.
Sun Haiping almost lost his chin in front of Ersha Island's "black technology" and "epoch-making" equipment.
But that is still based on scientific and technological strength, not a real theoretical system.
So now.
He completely understood.
Why is the gap so big?
Technology and theory are compared in all aspects. If the gap is not big, then there is a ghost.
There are some things that I have never heard of or seen in China.
And just when he sighed, "What is professional? This is called professional."
One sentence in it completely made him feel like his body was numb.
This sentence is——
"Now proceed to your detailed analysis phase."
Sun Haiping:......
What the hell.
Before Qingqing, it wasn't "detailed", but just "general"?
Crazy, really crazy.
Only when you come to Ersha Island will you realize how little you know about running.
same.
Only when you come to Ersha Island will you realize how much these people know about running.
Just this, the so-called number one track and field coach in the country, was completely shocked to his core.
ps: The devil has gone crazy in the past two days. The project has not been completed well, and she is madly "pushing" us to make changes. It is really terrible, terrible.
