The Su God of the Reopening of the Sports Arena

Chapter 1246 A replay that can predict even the opponent's toes!This is the real future!Join or be eliminated!
Recently, because there are not many games, Su Shen has entered a short period of rest and adjustment.

At this time, it is mainly to do tactical analysis and technical review.

Not only do you make your own, why this gun 9.73s can run out, the angle of each step, you can even analyze whether it is perfect or not.Although the data is only theoretical, it can at least tell you that you still have room for optimization.

This will give the athlete the motivation to keep working hard.

The second is to teach Xie Zhengye to learn the real and systematic "scientific wind control technique".

Then there is the opponent...

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

This is something that you couldn't do without a scientific team before, because this analysis is not just a few words.It can only be achieved by practical technical details and detailed data.

Otherwise, it's pointless.

This is also what Su Shen will do after every game now.

Never let go of any opponent easily.

Regardless of the state of the opponent's game, you will not find the answer from the opponent's remarks, nor guess it yourself, but find the answer from the scientific running data.This is the review brought by the scientific team. Compared with the previous review, it can only be said to be...

The gap is too big.

"Before the resumption, let us welcome Coach Zhou Wei and Coach Li Tao who have recently applied for transfer 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 sit down, both of you, and we'll start right away."

Both Zhou Wei and Li Tao were former national record holders, and the latter even set a new Asian 100-meter record.

Now they are all coaches, one leading the sports school at the grassroots level to accumulate experience for himself, and the other is a senior coach in the Sichuan Sichuan team.

Because there is no Olympic Games and World Championships this year, they can all spare their hands and come to study hard.

Before OW, Zhou Wei also worked as an assistant coach in other provincial teams. In fact, it was not easy to spare time.

This time, they really entered the Su God Department, and the two of them can finally take a good look at what kind of magic this Su God Department, this Ersha Island, has, which can improve the athletes so much and increase the sprint team's winning rate in the international game. , The final rate is getting higher and higher.

The lights in the room dimmed, and the game began to play.

After running, start to analyze step by step.

"This is a loop play for several people through Dartfissh. We talked about Su God earlier. Now let's focus on Su's opponents, Tyson Gay, 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 division, and finally use the software to test the key data nodes."

"Basic segmentation 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 that in this game, Bolt's acceleration was slow except for the slow start, and the running on the way was even more messy. Green said before that Bolt's technical movements are not particularly good. Now in this game, it can be regarded as relatively obvious. First, let’s look at the characteristics of the two players in this game. In this game, Guy used 46.46 steps, and Usain Bolt used 42.24 steps. Then we look at the average Gay’s cadence is 4.679s, Bolt’s is 4.257s, then the cadence index of this game can be obtained, Gay’s 8.422, Bolt’s 8.343s, and then look at Gay’s average stride length in this game , is 2.192m, Bolt is 2.404m, the former's step index is 1.217, and the latter is 1.226."

"This is the basic test data. We all know that stride length and stride frequency have a greater impact on athletes' fastest speed level and [-]-meter performance. The simultaneous development of stride frequency and stride length ensures the improvement of sports performance. Step length and stride frequency are mutually restrictive and interdependent. Factors that affect step length include: leg length, force and direction generated by the leg, amplitude of lower limb swing, body coordination, flexibility of joints, elasticity of the runway, and wind direction of the field etc."

"Factors known to affect stride frequency include the following aspects: the flexibility of the athlete's nerve process, the side to side movement of the lower thigh, the muscle strength of the joints and legs, the degree of muscle contraction, the coordination of the movement organs, etc. On this basis, we use the step length index and frequency index to study the step length and stride frequency ability of the 8.422-meter sprint, so as to reveal the essential characteristics of the two people in the 8.343-meter sprint. First, based on the height factor, through the From the calculation and statistics of Gay and Bolt's stride length and stride frequency index, we can see that: first, from the perspective of stride length and stride frequency index, Gay's is 6.63, and Bolt's is 0809. Under the same circumstances, the longer the length of the lower limbs, the greater the swing of the lower limbs, the greater the rotational inertia, and the slower the swing of the legs, the lower the stride frequency. This is the advantage of the [-]-meter sprint. Because of the height, two people There is not much difference in the stride frequency and stride length, Bolt's stride length is slightly longer. In actual combat, whether it is adjusting the stride frequency, or adjusting the stride length, or Adjusting the two methods at the same time will cause a lot of 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 point of view, in this game, Guy has a low center of gravity in the first half, and his feet are fast on the shears and angled. Big, so his feet are moving a lot on the scissors. Bolt has a problem with the center of gravity here, and he hesitated at the start. The core muscle control, especially when starting the scissors, is worse than usual. A lot, resulting in only [-]s for the future, completely inferior to his [-] race. But in this respect, Sue's performance before entering the sprint zone was much better, as I said yesterday, I won't say more."

Randy quickly continued as if no one was around: "Running is a very cyclical exercise. A running cycle can be divided into two motion cycles of support and flight. The speed of the pace depends on the support of the soles of the feet and the time off the ground. We can see here that roughly Gay'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 air time, Bolt's speed Be faster than Guy. According to the current theory of biomechanics, the longer your action lasts, the greater the shock force you receive. In this way, Guy gets more momentum, and Guy steps out The distance of Gay is farther than that of Bolt, and Gay’s average step frequency is slightly higher than that of Bolt. Under the same circumstances, the same step length, step frequency, and step speed are all faster. In a take-off time and In terms of support ratio, the world's top athletes have a support-to-support ratio of approximately 1.2:1 in mid-runs."

"So it can be concluded that in this game, Bolt's tandem ratio is also a complete failure."

"He wants to be faster, he has to shorten the support time, and at the same time shorten the air time."

"Let's talk about the angle analysis of the ankle, knee and hip joints in the process of running with support. The three stages of front support, rear support and flight are all represented by the magnitude 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 Guy hit the ground, the ankle joint angle reached 126.5 degrees, and then at the moment of vertical buffer, the ankle joint angle reached 86.4 degrees. The angle reached 40.1 degrees, and the buffer angle reached 137.5 degrees. The moment the back support kicked and stretched, the angle of the ankle joint reached 51.3 degrees, and the range of toe flexion reached [-] degrees. Here you can find that his ankle joint landed to the buffer retreat It has the characteristics of a large range of motion with kicking and stretching force. And because the ankle joint angle is larger, it shows that Guy's ankle joint strength is better in this game, so the ankle joint angle can increase the landing angle at the moment he hits the ground, so that The step size increases."

"From the angle of the knee joint, the smaller the angle of the knee joint, the better for muscular contraction, which in turn reduces the kickback angle. Guy's knee joint angle is 7.9° less than that of Bolt, and he is more handy. He accelerates horizontally forward. ability. The force-generating joints during the running process lie in the ankle, knee, and marrow joints, and because the hip joints have more muscle fibers, this part of the joints is in the most critical position. In a single-step movement, The hip joint performs hip delivery work. Although Gay’s hip joint movement range is 2.1° smaller than that of Bolt’s, it is beneficial to the centrifugal work after contraction and is more conducive to the range of motion of Guy’s hip joint. This shows that: Bolt’s joints The flexibility is slightly worse than Gay in this game, which is not conducive to the huge muscle strength of the muscles kicking back, which affects the improvement of horizontal speed."

"Look at the landing angle Gay is 126.5, Bolt is 119.3..."

"So Gay's 6.412s in the future is significantly ahead of Bolt's 6.632. Bolt can only be considered to have played out in the latter part of the game. The data has not declined much compared to last year. Guy's 3.428s in the latter part of the journey, Bolt's 3.338s .The latter is about 0.1 ahead and go back.”

"It's a pity that the front is too far behind, making it impossible to catch up. It is estimated that Bolt's start was too fast twice in a row, and he didn't run, which made his current physical reserves unable to load, and his heart and lungs could not load. Greatly out of order."

"But this is not the state Bolt should be in. Judging from the future, he is actually better than Paris. It may not be easy to confront Bolt right now. Perhaps, He's back to 9.73s and even 9.72s as well."

"Maybe even higher."

"This game is hard to say."

"Therefore, we must not underestimate him. We should not underestimate the opponent just because he did not seem to run well in this game, thinking that the opponent's state has been greatly reduced. Considering normal circumstances, he may be much tougher than everyone thinks. "

When Randy led the technical team to give explanations and technical analysis, the whole scene was concentrated.

None of them had any intention of taking a nap.

Except for the last two people, they were really dumbfounded.

……

After the whole game, Zhou Wei saw the power of Su's divine system again, except that he was in the waiting room last time.

As soon as he came out, he felt like he was listening to a bible, and even felt that he was a little numb throughout the whole process.

He turned his head to look at the more experienced senior Li Tao, wanting to ask for help, but unexpectedly Li Tao said generously, "Don't look at me, I didn't understand either."

"But, is this their replay?"

"It's really a big saw in the butt, it's an eye-opener."

Thinking of this, and thinking about my past replays, it's really...

Completely became the five scum of war.

Not worth mentioning.

It is simply the gap between the Hongtao Spear and Gatling.

The difference between a strong bow and a hard crossbow and a rocket launcher.

Those technical indexes and technical parameters that they don't even know very well, now they can use them freely, even to the point of picking from one angle to another.In the past, this was unimaginable at all, but now with models, systems and powerful computing power, everything has become feasible.

In fact, this does not need to be too complicated. Computers in the 90s can easily handle it, even if there was no software development in this area back then.

"Hehe, through a series of data such as the angle of the ankle joint, the range of toe flexion, and the buffer angle of the back support, it can be directly concluded that Gay's ankle joint strength is better in this game, and Bolt's ankle joint strength is insufficient. , so it can be deduced why Guy's average step index has increased in this game, and Bolt's average step index has decreased..." Li Tao lit a cigarette, and his thoughts were obviously still in the replay observation room , Looking at the sky and saying: "It can accurately know which technique, even which joint, and even which angle of the athlete has a problem in this game, and directly determine where there is a mistake. It is as precise as a scalpel... And we used to just say some general words, and if someone gives a detailed data, we will rub it on the ground for you."

"Do you think so because you have so much experience?" Zhou Wei had just switched to the coaching industry not long after all, and thought that a veteran like Li Tao would be different, but he took a puff of a cigarette, looked at him and said indifferently: "Experience? "

"You saw it too."

"Is our so-called 'experience' that is so precious to us really useful?"

"Hehe, there is a hairy use."

Li Tao threw the cigarette butt that was almost finished on the ground, stepped on it with his heel a few times, and said, "It's too far away."

"Taking one of these issues out, we may have to study for half a year or even several years before, but we can't figure it out, or even get it wrong. Now people can do it like acupoints, and they are targeting everywhere, and the trick is deadly."

"Data, models, small knowledge, and the power of science seem to be an irresistible trend in the future."

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

"Our land in the future."

"You don't learn."

"Maybe I don't even have to eat."

Hearing Zhou Wei's words, he was immediately frozen. After all, everyone knew who Li Tao was and who his master was.

That was one of the best coaches of the national team before, and also the fastest athlete in the country, the first super master who ran to [-] seconds and tied 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.

And after listening to this class today, Zhou Wei himself was completely shocked by this kind of super replay, super data, super model, which is like "peeling and digging for you".In the past, things that could not be analyzed by myself for a few days may be in the wrong direction. Now people use these to make accurate judgments. If you run well, there is a problem with which muscle.”

Such a shock is completely incomprehensible to their generation.

It was as if the Qing government stood 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 are the people on Ersha Island making progress so fast?
Why is the winning rate of people from the Su God Department so high?
Simply genius?Just a training method?Just training ideas?

No, I thought I knew everything.

Looking at it now, people's post-war replays are so scary, surpassing the number of domestic versions that I don't know.

Even a few years ago, it was a bit of metaphysical magic.

It was only then that Zhou Wei realized that they were powerful, and they were all the result of pondering and researching in all aspects.

It doesn't matter if one aspect stands out, that's fine.

This is real sports.

This is the sports of the future.

Just like what Li Tao said.

You do not join.

Just eliminated.

There is no choice.
