Chapter 1240 A replay that can even predict the opponents toes! This is the real future! If you dont join, you will be eliminated!
Since there haven't been many games recently, Su Shen has entered a short period of rest and adjustment.
At this time, the main thing is to do tactical analysis and technical review.
Not just doing your own thing, but why this shot can run in 9.73 seconds, and the angle of each step, you can even analyze whether it is perfect. Although the data is only theoretical, at least it can tell you that you still have optimization
Space.
This will give athletes the motivation to continue working hard.
The second step is to teach Xie Zhengye to learn the truly systematic "scientific wind control technology".
Then there are the opponents...
Yes, technical analysis of opponents must also be done.
This is something you couldn't do without a scientific team in the past, because this analysis is not just a few words. It requires practical technical details and detailed data to be done.
Otherwise, it is meaningless.
This is what Su Shen does after every game now.
Never let go of any opponent easily.
No matter what the opponent's game status is in this game, we don't look for it from the opponent's comments or make our own guesses, but find the answer from the scientific running data. This is the review brought by the scientific team. Compared with the previous review
Pan, can only be said to be...
The gap is too big.
"Before the review, let us welcome Coach Zhou Wei and Coach Li Tao who have recently applied to be transferred to study for a period of time." Zhang Quan said: "I believe everyone is familiar with who these two are, and there is nothing to introduce.
Yes, please take a seat, you two, and we will start directly."
Zhou Wei and Li Tao are both former national record holders, and the latter set a new Asian 100-meter record at the age of eighteen.
Now they are all coaches, one leads a sports school at the grassroots level to gain experience for himself, and the other is a senior coach in the Sichuan-Sichuan team.
Since there are no Olympic Games and World Championships this year, they can all spare their time and come over to study hard.
In the previous year, Zhou Wei also worked as an assistant coach for other provincial teams. In fact, it was not easy to find time.
Now, the Su Shen system has really come in. The two of them can finally take a closer look at what magic this Su Shen system and Ersha Island have, which can make athletes improve so much and increase the sprint team's card winning rate in the International Bureau.
,The finals rate is getting higher and higher.
The lights in the room dimmed, and then the game started playing.
After finishing the run, I started to analyze step by step.
"This is a loop played by several people through dartfissh. We talked about Su Shen earlier. Now let’s focus on Su’s opponents, Tyson Gayin, Asafa Powell, and Usain Bolt.
." Randy led the team in front and began to explain in detail: "It is better to calculate the single frame time first, then calculate the time of each distinction, and finally use software to test the key data nodes."
"We can see that in this game, Bolt not only slowed down at the start, but also accelerated slowly, and his running was even worse. Green has said before that Bolt's technical moves are not special.
Excellent, now in this game, it is more obvious to realize it. First of all, let’s look at the characteristics of these two people in this game. Gai Yin used 46.46 steps in this game, Usain Bolt used 42.24 steps, and then we
Look at the average cadence of Gai Yin is 4.679s and Bolt is 4.257s. Then we can get the cadence index of this game. Gai Yin is 8.422 and Bolt is 8.343s. Let’s look at Gai Yin’s cadence index in this game.
The average step length is 2.192m, Bolt is 2.404m, the former’s step length index is 1.217, and the latter’s step length index is 1.226.”
"This is basic test data. We all know that step length and step frequency have a great impact on an athlete's fastest speed level and 100-meter performance. The simultaneous development of step frequency and step length capabilities ensures the improvement of sports performance.
Step length and step frequency are mutually restricted and interdependent. The factors that affect step length are: leg length, the force and direction generated by the legs, the amplitude of lower limb swing, body coordination, joint flexibility, track elasticity, and the wind direction of the field.
etc."
"It is known that the factors that affect the cadence include the following aspects: the flexibility of the athlete's nerve process, the ratio of the lower leg movement link, the muscle strength of the joints and legs, the continuity of muscle contraction, the coordination of the action organs, etc.
.On this basis, we use the step length index and frequency index to study the step length and step frequency ability of the 100-meter dash, thereby revealing the essential characteristics of the two people in the 100-meter dash. First, based on the height factor, through the
From the calculation and statistics of the step length and cadence index of the two players Gai Yin and Bolt, we can see that: first, from the perspective of step length and cadence index, Gai Yin is 8.422 and Bolt is 8.343.
Under the same circumstances, the longer the length of the lower limbs, the greater the swing amplitude and rotational inertia of the lower limbs. The slower the leg swing speed, the lower the cadence. This is the advantage of the 100-meter dash. Because of their height, two people
There is not much difference in step frequency, and there is not much difference in step length. Bolt's step length is slightly longer. In actual combat, whether it is adjusting the step frequency, adjusting the step length, or
Adjusting both methods at the same time will cause great variables. Of course, everyone's step length and number of steps are different, which will greatly affect the fastest speed of each sprint and the performance of each sprint.
If you deliberately increase the number of steps, it will lead to a decrease in stride frequency. From this perspective, in the first half of this game, Gai Yin's center of gravity was very low, and his feet moved very quickly on the scissors, and the angle was very
Big, so his feet move a lot on the scissors. Bolt has a problem with his center of gravity here, and he hesitates to start. His core muscle control, especially when starting the scissors, is worse than usual.
A lot, resulting in a future of only 6.63s, completely inferior to his 2008 race. However, in this regard, Su’s performance before entering the sprint area was much better. I mentioned it yesterday, so I won’t say more.”
Randy continued quickly and calmly: "Running is a very cyclical sport. A running cycle can be divided into two movement cycles: support and airborne. The frequency of steps depends on the support of the soles of the feet and the time it takes to leave the ground.
. We can see here that roughly Gai Yin’s support time is 0.100 seconds, 0.114 seconds, Bolt’s support time is 0.067 seconds, and 0.100 seconds. In terms of support and flight time, Bolt’s speed
Faster than Gai Yin. According to the current theory of biomechanics, the longer your action lasts, the greater the countershock force you receive. In this way, Gai Yin gets more momentum, and Gai Yin takes one step forward
The distance is farther than that of Bolt, and Gayin's average step frequency is also slightly higher than that of Bolt. Under the same circumstances, the same step length, step frequency, and step speed must be faster. In a take-off time and
In terms of the ratio of support points, the ratio of support points to support points during mid-race running by the world's top athletes is approximately 1.2:1."
"So it can be concluded that in this game, Bolt's stand ratio was also completely defeated."
"If he wants to go faster, he must shorten his support time and shorten his flight time."
"Let's talk about the analysis of the angles of the ankle, knee and hip joints during running with support. The three stages of front support, back support and flight are all represented by the amplitude of the angle. The specific data of these three periods are mainly
It is determined by the changes in the angles of the ankle, knee, and hip joints. Through the analysis of the video, we can see that the moment Gai Yin landed on the ground, the ankle joint angle reached 126.5 degrees, and then at the moment of vertical buffering, the ankle joint angle
The angle reached 86.4 degrees, and the buffer angle reached 40.1 degrees. The moment the rear support push-and-extension was completed, the angle of the ankle joint reached 137.5 degrees, and the range of toe flexion reached 51.3 degrees. It can be found here that his ankle joint touched the ground and gave way to the buffer.
He and pedaling extension force have the characteristics of a large range of motion. And because the ankle joint angle is larger, it shows that Gai Yin's ankle joint strength performance is better this time, so the ankle joint angle can increase the landing angle at the moment he lands, thus making
The step size increases.”
"From the perspective of changes in knee joint angle, the smaller the knee joint angle is, it is conducive to muscle contraction, which in turn reduces the back pedaling angle. Gayin's knee joint angle is 7.9° less than Bolt's, which makes it easier for him to accelerate forward horizontally.
ability. The force-generating joints during mid-range running are the ankle, knee, and spinal joints, and because the hip joint has a larger number of muscle fibers, this part of the joint is at the most critical position. In a single step,
When the hip joint performs hip movement, although Gai Yin's hip joint movement range is 2.1° smaller than Bolt's, it is conducive to the eccentric work after contraction and is more conducive to Gai Yin's hip joint movement range. This shows that Bolt's joints are flexible
The performance is slightly worse than that of Gai Yin in this field, which is not conducive to the muscle back kicking to produce huge muscle strength and affects the improvement of horizontal speed."
"Look at the ground angle Gai Yin is 126.5, Bolt is 119.3..."
"So in the future, Gai Yin's 6.412s is significantly ahead of Bolt's 6.632. Bolt's performance is only in the later stages. The data has not declined much compared to last year. Gai Yin's latter stage is 3.428s, and Bolt's is 3.338s. After that,
Cheng went back probably 0.1 ahead."
"It's a pity that the front is too far behind and it is impossible to catch up. It is probably that Bolt started too fast twice in a row and did not start running, so that his current physical reserves cannot be loaded, and his heart and lungs cannot be loaded, resulting in poor performance ahead.
Substantially abnormal.”
"But this is not the state that Bolt should be in. Judging from what will happen later, he is actually better than Paris now. It may not be easy to fight Bolt now. Maybe,
He's also back up to 9.73s and even 9.72s."
"Maybe higher, maybe."
"This game is hard to say."
"Therefore, we must not underestimate him. We cannot underestimate the opponent just because he does not seem to be running well in this game, thinking that the opponent's condition has been greatly reduced. Considering normal circumstances, he may be much stronger than everyone thinks.
"
When Randy led the technical team to give explanations and technical analysis, the entire scene was attentive.
No one had any intention of taking a nap.
Except for the last two people, they were really dumbfounded.
…
After the whole game, apart from the last time he was in the lounge, this time Zhou Wei once again saw the power of the Su Shen system.
As soon as he came out, he felt like he was listening to a book from heaven, and even felt that his mind was a little numb throughout the whole process.
He turned to look at his more senior senior Li Tao, wanting to ask for help. Unexpectedly, Li Tao said openly: "Don't look at me, I don't understand either."
"But is this their review?"
“It’s really a big saw in the ass, it’s an eye-opener.”
Thinking of this, and then thinking about my past reviews, it’s really...
He has completely become a scumbag.
Not worth mentioning.
It’s basically the difference between Hongying Gun and Gatling.
The difference between strong bows and crossbows and rocket launchers.
They are now able to use the technical indexes and technical parameters that they don’t even understand very well, even to the point of picking them from angle to angle. In the past, this was unimaginable, but now we have models, systems, and powerful tools.
Computing power, everything, has become feasible.
[In view of the general environment, this site may be closed at any time, please move to the permanently operating source app, huanyuanapp as soon as possible]
In fact, this does not need to be too complicated. Computers in the 1990s could easily handle it. Even then, there was no software development in this area.
"Haha, through a series of data such as the angle of the ankle joint, the range of toe flexion, and the back support push-extension buffer angle, it can be directly concluded that Gai Yin's ankle joint strength performance was better in this game, and Bolt's ankle joint strength performance was insufficient.
, so we can conclude why Gai Yin’s average step index has increased and Bolt’s average step index has shrunk in this game..." Li Tao lit a cigarette, and his thoughts were obviously still in the review observation room.
, looking at Buhuibubaitiantian said: "You can know exactly which technique the athlete is using in this game, even which joint, and even which angle is problematic, and directly determine where mistakes have occurred, as precise as a scalpel...
But we used to just talk in general terms, and if someone gives you detailed data, it will completely knock you to the ground."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "You have so much experience, do you think so?" After all, Zhou Wei had just switched to the coaching industry not long ago, and he thought that a veteran like Li Tao would be different.
, as a result, the man took a puff of the cigarette, looked at him and said calmly: "Experience?"
"You saw it too."
"In terms of data that is so detailed that you can reach your toes, is our so-called 'experience' really useful?"
"Haha, it's useful."
Li Tao threw the almost finished cigarette butt on the ground, stepped on it with his heel a few times, and then said: "It's too far."
"If we take any of these problems, we might have to study them for half a year or even several years before we can't figure them out, or even get the wrong approach. Now people can do it just like tapping acupuncture points, and they can target them everywhere, and every move can be fatal."
"With data and models, we can see at a glance, and the power of science seems to be an irresistible trend in the future."
"Kid." Li Tao looked at Zhou Wei, a junior who had just retired a few years ago, and said, "Study hard."
"This is our land in the future."
"You don't learn."
"Maybe I won't even have to eat."
When Zhou Wei heard this, he was immediately stunned. After all, everyone knew who Li Tao was and who his master was.
He was one of the best coaches of the national team, the fastest athlete in the country, the first super master to break the ten-second mark and tie the world, and the proud disciple of Chen Jiaquan. If he said so, then...
I'm afraid if you really don't study hard, you won't have a chance to make a living in the future.
And after listening to today's class, Zhou Wei himself was completely shocked by this kind of super review, super data, and super model that is like "peeling your skin and digging out your bones". In the past, he might not have been able to analyze it for countless days.
Things may be in the wrong direction. People now use these to make accurate judgments. To put it bluntly, in the future it may develop to the point of "the athlete did not run well in a game, which muscle is the problem."
This kind of shock is an impact that people of their generation cannot understand at all.
It was just like the Qing government standing in front of the advanced thermal weapons of the Eight-Power Allied Forces.
He looked down at the spear and sword in his hand.
No matter how bright or sharp it is, it actually loses its meaning.
This is the leader of the entire era. If you don’t join, you will perish.
Why do people on Ersha Island make progress so quickly?
Why do people from the Su family have such a high winning rate?
Just genius? Just training method? Just training concept?
No, I thought I knew everything.
Looking at it now, the post-war replays are so terrible, surpassing countless domestic versions.
Even a few years ago, it had a bit of a metaphysical and magical meaning.
Only then did Zhou Wei realize that they were so powerful, and they were the result of all aspects of research.
It doesn't mean that just one aspect is outstanding.
This is real sports science.
This is the sports science of the future.
Just like what Li Tao said.
You don't join.
Just eliminate it.
There is no choice.
