Let's be a world champion first! [sports]

About Xing Yuanzhi's invitation, even You Yun was very surprised at first.

The track and field national team has a dedicated research team, and scholars and researchers in the scientific research department are conducting separate modeling studies on the technical adjustments and physical conditions of various athletes.

As for side running videos of athletes, including various side image studies of the start, acceleration, and mid-running stages, foreign countries already have a special motion analysis system that can refine the athlete's start reaction time-consuming, start preparation posture, and so on. Analysis and correction of running posture at different stages.

The national team has already introduced this system. The official members of the national team, such as Xian Wangxing, have used this system long before this. Every adjustment stage and post-adjustment posture correction effect of him have a special process. This system has been analyzed.

As for the members of the national team during the winter training period, at present, special running video recordings will be carried out on a two-week basis, and the output system will analyze the impact. In the end, it will also be discussed by the coaching staff members of the national team. The final discussion results will be It will be collected in the hands of the coaches who are in charge of designating players, so as to be used as the training basis for the next stage.

With these scientific arguments, Su Qian was invited to watch the side-running video alone. Even though You Yun had seen Su Qian's absolute talent in this observation ability with his own eyes, he still felt it was incredible.

It wasn't until Xing Yuanzhi talked with him in person that he knew that the origin still lay with Su Qian himself.

During the training camp of the national youth team, the coach of the national youth team led a group of U18 children to study side running videos. The purpose at that time was to improve the consciousness of U18 players in sprinting skills.

At that time, the coach in charge of teaching also saw that Su Qian did not seem to be certified to listen to the lecture, so he accidentally clicked on Su Qian's retelling of the content of the course, but in the end Su Qian's retelling of the detailed analysis of Xian Wangxing's side-running video really surprised the coach in charge of the lecture .

Later, the details of Su Qian's evaluation compiled by the coach were handed over to Xing Yuanzhi by Wang Liang. After that, after the analysis and demonstration of Xing Yuanzhi's team in the past half a year, it was true During Xian Wangxing's winter training, detailed adjustments were made to Xian Wangxing's training items.

As for the results of the adjustments, it can be said that the results have been remarkable.

After achieving clear results, it was Xian Wangxing who proposed it—since Su Qian has this ability, why not try to let him watch other people's siderunning videos?There may be more surprises.

Xing Yuanzhi is not a stubborn old man with a rigid mind who cannot listen to opinions. After all, the key points related to Xian Wangxing's technology that Su Qian raised before have indeed achieved results.

Since it is effective, let Su Qian watch other side running videos. The only thing that will be delayed is about a day or two of Su Qian's training time, so there is this invitation.

As for Su Qian, who was the invitee, he himself didn't think too much about it. After hearing You Yun's arrangement, he obediently nodded his head to show that he understood.

The national team's internal side-running video analysis meeting was scheduled between 5 pm and 8 pm every day.

It's not just Su Qian, the coaches of the sprint team who are free will go to the designated meeting room to watch the video together and analyze it individually.

At 5 o'clock in the afternoon the next day, Su Qian had already finished his training for the day ahead of schedule, and followed You Yun to the conference room.

There are more than a dozen coaches sitting in the conference room that can accommodate 50 people. There are coaches for each group of sprints of 100, 200 and 400 meters.

After Su Qian followed You Yun into the conference room, these coaches also looked at Su Qian curiously, they were all friendly, but most of them were a little curious.

Su Qian was very courageous, let the coaches watch, and would smile and say hello to the coaches he knew.

Qiu Mingxin and Tian Wenhan were also in the meeting room, and they both smiled when they saw Su Qian.

Not long after, Xing Yuanzhi also arrived, and the conference room was almost full.

This was the first day of the analysis meeting, and the coaches of the sprint group were relatively complete, but Xing Yuanzhi didn't say anything, but after seeing that everyone was here, he signaled his assistant to start playing the side running video.

The side running videos to be shown are all simply classified according to the videos of the players of different events and the videos of the same player in different cycles.

In the analysis meeting on the first day, it was mainly the winter training participants of the 100-meter sprint event.

Headed by Xian Wangxing, followed by Liu Wei, Guo Zhaolin, Qi Wei, Zhou Yiming, Chen Liang, Jiang Wenze, and finally Su Qian's side-running video.

If it is an ordinary player, sitting in a conference room with a group of coaches and doing side-running video analysis, probably the head will go numb, especially if there is a video of yourself included, it will be very embarrassing.

But Su Qian is perfectly adapted to this.

Not to mention that he is in the dream space, his devil coach Su Bai will randomly ask him these questions every day, even in reality, every time he starts the live broadcast beep beep, the audience in the live broadcast room will not compare with the analysis meeting. There are fewer coaches on site.

From the moment when the assistants in the conference room played the siderunning videos of the players one by one in a loop according to the number requested by Xing Yuanzhi, the conference room entered an extremely quiet state.

Su Qian focused on every video image on the projection screen—in order to simply obtain a more pure and intuitive reaction from the coaches, the images released this time have not been detected and marked by the motion analysis system. The only processing of these videos is, When playing, it will be played at 0.25x speed, 0.5x speed and original speed respectively.

If you don't have the relevant sprint system cognition and observation ability, then you can only look blank when you just watch these videos.

And the coaches in the conference room were holding their own training manuals and were recording the different problems they had observed on players with different numbers. Some of them were simply observing the video and were not in a hurry to start writing.

Sitting among these coaches, Su Qian focused on watching the video and recording the information in his hands, and he didn't feel any sense of disobedience at all.

Videos of athletes running sideways are shown in groups of individual athletes.

After the first group of Liu Wei's videos were played, the conference room was still quiet for more than ten minutes, and some coaches signaled the assistants to play back a certain clip again.

About ten minutes later, Xing Yuanzhi began to ask if anyone could start the video analysis of Liu Wei's siderunning first.

After all, the coaches here are all coaches who can be selected for the national team. They are not weak in terms of vision and observation ability. Even if there is no auxiliary line drawn by the sports analysis system, the eyes of these coaches have already been trained.

After Xing Yuanzhi spoke, a coach soon raised his hand to signal and began to conduct corresponding video analysis.

Liu Wei is 25 years old. He is one of the few players in China who can run the 10 meters within 30 seconds. Unlike Guo Zhaolin and Qi Wei, who are not in good form this season, Liu Wei has maintained a relatively good performance this season. grades.

The coaches of the national team's coaching staff have actually done Liu Wei's relevant analysis many times.

Liu Wei's explosive power is strong, and his overall running and kicking efficiency is not weak, but compared with his benchmark performance, the data in the middle and late stages is not ideal.His best running stage is basically at the start burst stage. In a game, as long as Liu Wei does not make too many mistakes in the start burst stage, he can basically guarantee that he will have a relatively good result in this game.

At the same time, if he performs well in the mid-to-late distance, he has a chance to run under 10 seconds.

In response to Liu Wei's problems in the middle and late stages, his coach has also made a lot of efforts, such as increasing Liu Wei's speed endurance training and improving Liu Wei's ability to maintain the maximum speed, but with little effect.

In terms of running posture, Liu Wei's running posture is relatively standard, because he has strong explosive power and his own strength conditions. In the starting stage, Liu Wei's preparatory posture will appear relatively large in terms of body tilt angle, which is more tightened. The preparatory posture is to allow him to explode better at the starting stage.

And many coaches on the scene pointed out that Liu Wei's posture was insufficient in his initial explosive stage, and at the same time gave more or less their own opinions.

After speaking one by one at the scene, Xing Yuanzhi set his eyes on Su Qian.

"Su Qian, do you have any opinions of your own?"

All the coaches present knew that the reason why Su Qian was called to hold this analysis meeting was because his previous opinions had been well verified by Xian Wangxing.

So, after hearing Xing Yuanzhi click on Su Qian's name, there was a hint of curiosity in his eyes.

Facing the gaze of a group of national team coaches, Su Qian was not afraid.

Liu Wei's problem, he actually discovered it a long time ago, when he was only broadcasting live broadcasts on the Internet.

Su Qian thought for a while, and asked the assistant who was playing the video to cut the screen to a still frame during Liu Wei's running, and then said: "I think Wei Ge's hip-sending action is habitually broken, which probably caused his A key factor that makes it difficult to improve the rear speed."

Hip sending action is a bit broken?

The coaches present were stunned for a moment. Hip sending is the basic ability of sprinters. If Liu Wei has problems with the technical movement of sending hips, he will not be able to run to the current level.

Su Qian didn't pay attention to everyone's questioning looks, he was still pointing at the still frame of Liu Wei's running sideways video at this moment, and simply took over the computer control from the assistant.

The software they used to play the side-running video is a software that can select and display the screen frame by frame, and can also use the simulated electronic pen to make temporary screen key marks.

After Su Qian selected two still frames at a certain point, he circled another point on the screen with a marker pen: "Wei Ge's current hip-sending action, his body movement changes, if according to the standard Let’s see, the next second the landing point should be at the point A I drew.”

The coaches present looked at the projected screen at the same time, saw the mark made by Su Qian, looked at each other, and finally nodded.

After Su Qian saw the coaches present nodding, he directly cut the projection to the next still frame of Liu Wei—then the coaches on the scene saw the slight difference in the landing point in the picture, and they were slightly surprised and a little surprised The results you see before your eyes.

In fact, the entire hip movement is a fluid dynamic picture in terms of hip swing and hip flexion. It is not that the coaches present have not analyzed these movements of athletes frame by frame before, but even with the help of motion analysis System, these tiny differences are not easy to attract their attention.

Athletes are not robots after all, and it is impossible to achieve absolute standards in every movement. In fact, the same technology will be modified to be more suitable for individual athletes in different athletes. It is difficult for me and the long-term coach in charge of the athletes to tell whether it is the movement error or the adaptive adjustment of the athletes.

For example, the error in Liu Wei's hip sending movement drawn by Su Qian is a part that is rarely noticed.

But after Su Qian really draws this error interval, and then repeatedly mobilizes Liu Wei’s follow-up relevant part of the static frame, you can see that as Liu Wei enters from the accelerated run to the halfway run, his error interval always exists. And there are ups and downs.

Under the influence of the lines marked by Su Qian, it can be seen that the error in the hip sending movement caused Liu Wei's insufficient kicking and extension.

In the process of Liu Wei running at full speed, with his movement difference, it directly led to the weakening of his own strength.

In other words, Liu Wei's own strength is very sufficient, but under this movement error, his own strength cannot be fully converted into his own running speed.

After Su Qian finished explaining Liu Wei's case, the coaches in the entire conference room applauded spontaneously.

Xing Yuanzhi also had full approval on his face. He invited Su Qian to participate in the analysis meeting. He didn't have full expectations at first, but Su Qian's observation skills far exceeded his expectations.

He couldn't help thinking of something that Yang Xiulei and Wang Liang had repeatedly mentioned to him - Su Qian's talent for sprinting is very strong, but Su Qian's talent for coaching will definitely not be weaker than his talent for sprinting.

Xing Yuanzhi didn't think so before, but in today's meeting, he really understood Su Qian's absolute talent in the position of coach.

outside the meeting room

The winter training of the national team has been going on for some time, and the sports channel recently planned a winter training visit to the base of the track and field national team.

Today is the day when the sports channel came to visit the base. Cao Qingshan, the deputy director of the field management center directly in charge of the national team, brought the reporters of the sports channel into the training base of the national team. The status of the athletes after the end.

At this moment, the athletes and coaches of other sports are interviewing, but the head coach of the sprint group, Xing Yuanzhi, is still in a meeting. The reporters who came to interview are not in a hurry, so they chatted with Cao Qingshan outside the meeting room Get up and wait for the meeting inside to end.

They have all inquired about it, and this is a video technical analysis meeting for the sprinters in the side-running group.

As a result, they were waiting, when suddenly there was a burst of applause from inside.

"Hey, Director Cao, is there applause inside? Is there any new discovery?" The reporter is very excited, which means that his interview today will be rewarding.

Cao Qingshan looked in the direction of the conference room, looking forward to it: "Wait, wait until they come out and see."

Cao Qingshan would never randomly knock on the door to enter this kind of technical analysis meeting. The coaches are discussing a problem. Who knows if his sudden intrusion will affect the discussion inside?

Several people just waited outside like this. It was about 8 o'clock when the door of the conference room finally opened, and coaches came out one after another.

The reporter immediately walked to the door of the meeting room with a smile, knocked on the door, intending to see if Xing Yuanzhi was free at the moment.

As a result, when he knocked on the door, he saw a child in the conference room?

Hey, that's... the youngest winter trainer in the sprint group, Su Qian? !
