Recently, because there are not many competitions, 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, why can this shot be run out of 9.73s? The angle of each step can even be analyzed whether it is perfect. Although the data is only theoretical, it can at least tell you that you still have room for optimization.

This will give athletes motivation to continue working hard.

The second is to teach Xie Zhengye to learn the truly systematic "scientific wind control technology".

Then the opponent...

Yes, the opponent's technical analysis must also be done.

This is something you could not do without a scientific team before, because this analysis is not just a few simple words. It requires practical technical details and detailed data to be able to do it.

Otherwise, it's meaningless.

This is what Su Shen does after every game now.

Never let go of any opponent easily.

No matter how the opponent's status is in this game, we do not look for the opponent's remarks or make up for it by ourselves, but instead look for the answers from the scientific running data. This is the review brought by the scientific team. Compared with the previous review, we can only say that it is...

The gap is too big.

"Before reviewing, let us welcome the latest application to transfer to study for a while, Coach Zhou Wei and Coach Li Tao." Zhang Quan said: "I believe everyone is familiar with whom you are, and there is nothing to introduce. Please sit down and we will start directly."

Zhou Wei and Li Tao are both former national record holders, and the latter even broke the 100-meter record in Asia at the age of 18.

Now they are all coaches, one is a grassroots sports school, who accumulates experience for himself, and the other is a senior coach in the Sichuan team.

This year, because there are no Olympics and World Championships, they can all take their hands and come and study hard.

In the past year of OW, Zhou Wei also worked as an assistant coach in other provincial teams. In fact, it was not easy to make time.

Now that I really came into the Su Shen system, the two of them could finally take a good look at what magic does this Su Shen system have, which can increase the athletes so much, and make the sprint team's card-winning rate and final rate in the international bureau be getting higher and higher.

The room lights dimmed and the game started playing.

After running, we started to analyze step by step.

"This is through Dartfissh's loop playback for several people. We talked about Su Shen before. Now let's focus on Su's opponents, Tyson Guy, Asafa Powell, and Usain Bolt." Randy led the team in front and began to explain in detail: "It's 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."

"The basic segmented data is as follows:"

“Reaction time 20m 40m 60m 80m 100m.”

“Guy 0.164 2.933 4.732 6.412 8.153 9.84 Bolt 0.176 2.946 4.751 6.632 8.243 9.97”

"We can see in this game, in addition to the slow start, Bolt's acceleration was slower, and the running was even more messy. Green had said before that Bolt's technical movements were not particularly excellent, and now this game is quite obvious. First, look at the characteristics of these two people in this game. Guy used 46.46 steps in this game, Usain Bolt used 42.24 steps, and then let's see the average step frequency Guy is 4.679s and Bolt is 4.257s. Then the step frequency index of this game can be obtained, Guy 8.422, Bolt 8.343s, and then look at Guy's average step length in this game, which is 2.192m, Bolt is 2.404m, the former step length index is 1.217, and the latter is 1.226."

"This is the basic test data. We all know that step length and step frequency have a great impact on athletes' fastest speed level and 100-meter scores. The synchronous development of step frequency and step length ability ensures the improvement of sports performance. Step length and step frequency are mutually restricted and interdependent. Factors that affect step length include: leg length, strength and direction of legs, amplitude of swinging of lower limbs, body coordination, joint flexibility, runway elasticity, wind direction of the field, etc.."

"The factors known to affect the pace frequency include the following aspects: the flexibility of the athlete's nerve process, the proportional side of the lower thigh movement, the muscle strength of the joints and legs, the coordination of muscle contraction, and the coordination of the movement organs, etc. On this basis, we use the step length index and the frequency index to study the step length and pace frequency ability of the 100-meter sprint, thereby revealing the essential characteristics of the two people in this 100-meter sprint. First, based on the height factor, the step length of the two players Guy and Bolt were compared with the step length of the two players.

, Calculation and statistics of the step frequency index, we can see: First, from the step length and step frequency index, Guy is 8.422 and Bolt is 8.343. In the same case, the longer the lower limb length, the greater the swing amplitude of the lower limbs, the greater the rotational inertia, and the slower the swing speed of the leg, the lower the pace frequency will decrease. This is the advantage of 100-meter sprint. Because of height, the pace frequency of the two people is not much different, and the pace length is not much different. Bolt's step

The length of the sprint should be slightly larger. In actual combat, whether it is adjusting the pace frequency, adjusting the pace length, or adjusting the two methods at the same time, it will cause great variables. Of course, each person'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 the pace frequency. From this perspective, in this game, Guy's center of gravity is very

Low, his feet are moving quickly on the slitting and the angle is also very large, so his feet are moving very large on the slitting. Bolt is having problems with the center of gravity here, and hesitated to start. The core muscle control, especially when starting the slitting, was much worse than usual, resulting in a future of only 6.63s, completely inferior to his 2009 competition. However, in this regard, Su's performance before entering the sprint zone was much better. I said it yesterday, so I won't say much."

This chapter is not over, please click on the next page to continue reading! Randy said quickly without anyone else: "Running is a very periodic exercise. A running cycle can be divided into two movement cycles: Support and Empty. The speed of the pace depends on the support of the soles of the feet and the time off the ground. We can see that here, Guy's support time is roughly 0.100 seconds, 0.114 seconds, Bolt's support time is 0.067 seconds, and 0.100 seconds. In terms of support and Empty time, Bolt's speed is 0.100 seconds.

The degree should be faster than Guy. According to the current theory of biomechanics, the longer your movement lasts, the greater the recoil force you will be. In this way, Guy gets more impulse. Guy takes a step further than Bolt, and Guy's average pace frequency is slightly higher than Bolt. In the same case, the same pace length, pace frequency, and pace speed are all faster. In terms of the ratio of a start-up time to the support point, the ratio of the support point to the support point during the run is about 1.2:1."

"So it can be concluded that in this game, Bolt's ten-support ratio was also completely defeated."

"He has to shorten the support time and at the same time he needs to shorten the air time."

"Let's talk about the angle analysis of ankle, knee and hip joints during running with support. The three stages of anterior support, posterior support and emptying are expressed by the amplitude of the angle. The specific data in these three periods are mainly determined by the changes in the angle of ankle, knee and hip joints. Through the analysis of the video, we can see that the ankle angle reached 126.5 degrees at the moment of landing, and then the ankle angle reached 86.4 degrees at the moment of vertical cushioning.

The buffer angle reached 40.1 degrees. The moment the rear support pedal was completed, the angle of the ankle joint reached 137.5 degrees and the toe flexion reached 51.3 degrees. Here, it can be found that his ankle joint landing to buffering and pedal strength had a large movement characteristics. Moreover, because the ankle angle was large, it indicates that Guy's ankle joint performance was better. Therefore, the ankle angle could increase the angle of the ground at the moment of landing, thereby increasing the step length."

"From the change of knee joint angle, the smaller the knee joint angle, it is conducive to muscle contraction, and thus narrowing the angle of back pedal. Guy's knee angle is 7.9° less than Bolt, which is more conducive to his ability to accelerate forward horizontally. The force joints during the running process are in the ankle, knee, and mastoid joints. Because the hip joint has a larger number of muscle fibers, this part of the joints are at the most critical position. In a single-step movement, the hip joints perform hip delivery work. Although Guy's hip movement amplitude is 2.1° smaller than Bolt's hip joint, it is conducive to centrifugal work after contraction and is more conducive to Guy's hip movement. This shows that Bolt's joint flexibility is slightly worse than Guy in this game, which is not conducive to the muscle back pedal to produce huge muscle strength and affects the improvement of horizontal speed."

"Look at the ground angle Guy is 126.5, Bolt is 119.3..."

"So Guy is significantly ahead of Bolt's 6.632 in the future. Bolt is only able to play in the later stage. The data has not declined much compared to last year. Guy's future is 3.428s and Bolt is 3.338s. The future is probably leading by 0.1."

"It's a pity that the front was too far behind, so it was impossible to catch up. It is estimated that Bolt's start-up was too fast for two consecutive times and did not run, which made his current physical reserves unable to bear, and his heart and lungs could not bear, resulting in a significant abnormality in his performance."

"But this is not the state that Bolt should have. Based on the subsequent future, he is actually better than Paris. It may not be easy to fight Bolt at the moment. Perhaps, he has also returned to the level of 9.73s or even 9.72s."

"It may be higher."

"This game is hard to say."

"So we must not underestimate him. We cannot be careless and underestimate the enemy just because this game doesn't seem to be running well, thinking that the opponent's condition is greatly reduced. Considering that under normal circumstances, perhaps he is much stronger than everyone thinks."

When Randy led the technical team to explain and analyze it on it, the whole scene was focused.

No one wants to take a nap.

Except for the last two people, I was really a little stunned.

...

After the whole game, Zhou Wei, except for the last time in the lounge, this time he saw the power of the Su Shen system again.

As soon as he came out, he felt like he was listening to a book of heaven, and even felt that he was a little confused throughout the whole process.

He turned his head to look at the more experienced senior Li Tao, who wanted to ask for help, but he didn't expect that Li Tao would say openly: "Don't look at me, I don't understand."

"But, is this their review?"

"It's such a big saw on my butt, and it's an eye-opener."

Thinking of this, thinking about my past review, it’s really...

He has become a complete defeated fight.

Not worth mentioning.

It's simply the difference between the Red Tassel and Gatlin.

The difference between a strong bow and a rocket launcher.

The technical indexes and technical parameters that they don’t even know very well are now used freely, and they even reached a situation of being able to figure out from one angle to another. This was impossible to imagine before, but now with models and systems and powerful computing power, everything has become feasible.

This actually doesn't need to be too complicated. Computers in the 1990s could be easily handled, and they didn't do software development in this area back then.

"Haha, through a series of data such as the angle of the ankle joint, the amplitude of toe flexion, the rear support and pedal and extension buffer angle, it can be directly concluded that Guy's ankle joint strength performed better in this game. Bolt's ankle joint strength performed insufficiently, so we can find out why Guy's average step size index increased in this game, and Bolt's average step size index decreased..." Li Tao lit a cigarette, and his thoughts were obviously still in the review observation room, looking at the sky without being gray and white, and said: "You can accurately know which technology the athlete is in this game, or even which joint, or even which angle there is a problem, and directly determine where there are mistakes, which are accurate like a scalpel... And we used to just say some general words, and someone will press them to the ground to rub them completely."

This chapter is not over, please click on the next page to continue reading! "Do you think so if you have such rich experience?" After all, Zhou Wei has just changed his career in the coaching industry. He thought that a veteran like Li Tao would be different. As a result, he took a sip of a cigarette and looked at him and said lightly: "Experience?"

"You saw it, too."

"In terms of the detailed and precise data that can be used to reach the toes, is our so-called "experience" that we cherish is really useful?"

"Haha, there's something for you."

Li Tao threw the cigarette butt that was about to be finished smoking on the ground, stepped on it with his heels a few times before saying, "The difference is too far."

"If we take one of these problems, we may have to study them for half a year or even several years before and can't figure it out, and we may even get the wrong way. Now people can do it like pointing acupoints, which is simply targeting them everywhere, and it is fatal to attack them."

"Data, models, and the power of science seems to be a trend that is really irresistible in the future."

"Little Devil." Li Tao looked at Zhou Wei, who had just retired for a few years, and said, "Study hard."

"Our land in the future."

"You don't learn."

"Maybe there is no need to eat."

After hearing this, Zhou Wei was locked up. After all, everyone knew who Li Tao was and who his master was.

That was one of the best coaches in the national team before and the fastest athlete in China. He was the first super expert to finish the world for ten seconds and win the world, Chen Jiaquan's proud disciple. If he said so, then...

I'm afraid I really don't study hard, and I won't have a chance to make a living in the future.

Moreover, after listening to this class today, Zhou Wei himself was completely shocked by this super review, super data, and super models that seemed to be "skinning and digging" for you. In the past, things that might not be analyzed for many days may be wrong. People now use these to make accurate judgments. To put it bluntly, they may develop to the point where "the athlete does not run well in a game, which muscle has a problem."

Such shock is an impact that their generation cannot understand at all.

It was like the Qing government stood in front of the advanced thermal weapons of the Eight-Nation Alliance back then.

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 leading position of the entire era. If you don’t join, you will perish.

Why do people on Ersha Island make so fast progress?

Why do people in the Su Shen system have such a high winning rate?

Just a genius? Just a training method? Just a training concept?

I thought I knew it all.

Now, when I see, the review after the war is so terrible, surpassing the domestic version.

Even a few years ago, it had a bit of metaphysical and magical meaning.

Only then did Zhou Wei realize that they were amazing and were the sum of the results that were all thinking about and researching in all aspects.

It's not just that it's outstanding in one aspect.

This is true physical education.

This is the future physical education.

Just like what Li Tao said.

You won't join.

Just eliminate it.

No choice.
