"What is Su Zu doing?"

"I don't know."

"I guess I'm tweaking the technique of running."

On the runway of the Haigen training base, in the morning, Zhang Peimeng, Su Bingtian, and Wen Yongyi saw Su Zu dangling on the runway. From time to time, I leaned over and started running, then adjusted a little more, and then leaned over again.

For a period of time, Li Zhizhong and Yuan Guohua both appeared on the sidelines of the arena, discussing something in a whisper, and chatting with Su Zu all the time.

Occasionally, there was a young man with a DV player who was beside the runway and had been filming Su Zu's movements.

Because of the training progress, in addition to the warm-up, although many of Suzu's regular training are together, the progress and training items are different.

"Brother Zhang, what is Su Zu doing?"

Zhang Peimeng came to Zhang Pingqiu's side and asked in a low voice, among several people, he was the first to come to the national team, and he was also familiar with Zhang Pingqiu.

"Su Zu discussed it with Director Li yesterday, thinking about optimizing the running technique."

Zhang Pingqiu glanced at it and explained to a few people. As an assistant coach, he knows a lot about the inside story. Su Zu actually put forward the idea of this aspect in the winter training last year, but at that time, he had just arrived at the Haigen training base for sub-plateau training, and the focus was different, so this item was temporarily shelved. And in this year's winter training, it is obvious that Su Zu wants to make some changes.

"Su Zu still wants to optimize technology?"

Zhang Peimeng and Wen Yongyi were a little stunned when they heard this, and Su Bingtian on the side was also at a loss. In their opinion, Su Zu is now the current holder of the men's 100-meter world record, the world's top sprinter, destined to go down in track and field history, the technique is already perfect, where do we need to continue to optimize the technique?

But at this moment, the facts are in front of several people, and it is not surprising.

Zhang Pingqiu looked at the expressions of several people, and then said: "Athletes must learn to think, after reaching a certain level, the coach alone may not be able to give too many suggestions, at this time, everyone needs to optimize some details according to their own situation."

You are still in the early stages of training, so you can only train according to the training plan and advice given by the coach. But there is a big problem with this, that is, the body is your own after all, and many times the intensity of training comes up, which may exceed the load of the body or the effect of the exercise is not good. For example, Zhang Peimeng, you often struggle with strength training, especially after putting on weights. That's not to say you can't, it's that your personal characteristics are different. In fact, reducing weight and increasing the number of sets can also have a good effect. Or change the form of training, such as squatting and you can't bear it, you can change to another way to strengthen your muscles and core. The adjustment of these details, the active excavation and adjustment of the athlete himself, is sometimes more significant than the coach's guidance. ”

"Training is a process of tapping the potential and limits of the human body, and the slightest changes bit by bit will accumulate and eventually become qualitative changes.

Director Li and Su Zu's training has always been like this, and Director Li will design a lot of various training methods for Su Zu, but most of the intensity and effect of these training methods are mastered by Su Zu himself. On the premise of ensuring that you are not injured or sick, you can improve as much as possible. ”

After saying this, his Chinese Yongyi did not care, he was older, not a few years different from Zhang Pingqiu, and he was a little tired of listening to this kind of preaching.

Zhang Peimeng frowned slightly, combined with what he had seen and heard, he had some ideas. And the newcomer Su Bingtian's eyes were shining, obviously these concepts were heard of for the first time.

Zhang Pingqiu didn't say much anymore, he followed Yu Liwei and Li Zhizhong in the past few years, and gradually formed his own style of coaching and observing athletes.

Athletes want to have the talent to achieve naturally the first place, and then the training attitude, that is, hard work. In addition to these accidents, the top athletes should have one more point, that is, a strong pursuit of victory, honor, and self-transcendence.

Be able to actively think about your own training style and improve your sports skills and skills.

At this point, it is not obvious that in the men's 100m, where talent is greater than effort, but for many events where skill and talent are combined, athletes who are constantly optimizing and improving their skills will inevitably go further.

At this time, Su Zu stood on the runway, and after finishing a run, he frowned, thinking about the feeling of running this time.

The DV machine that Yi Zhen was holding next to him handed it to Su Zu, and asked him to carefully read the posture of Fang Cai running by himself.

"Master, what do you think?"

Su Zu glanced at the footage from the start to the acceleration recorded in the DV machine, and then turned to Li Zhizhong, who was holding his hands behind his back, and asked.

"It seems feasible to reduce the length of your stride, but if you do this, it's a process of adaptation." Li Zhizhong frowned slightly and said.

"How long will it take to fully get used to it?" Su Zu was silent for a while and asked.

"Your technology is now formed, and if you change it, it's hard for me to say for sure." Li Zhizhong shook his head and said.

Su Zu thought for a while, and then walked to the starting line of the runway, "Let's try it first." I think 46 steps is too much, and my stride is not enough. Increase the surface base of the rear foot to land, and the force will be better. And then with the swing arm, I think I can still keep rushing forward. ”

Li Zhizhong nodded, Su Zu's current running style and technical points are probably the foundation he laid when he was in the Hedao City team.

The 100-meter run is 46 steps, and although there are occasional 45 steps, after the movement is fixed, it will probably continue to run at this pace in its entirety.

And now, with the improvement of Su Zu's strength, cadence and other aspects, 46 steps per 100 meters is already a bit too much for Su Zu.

Su Zu's current height is between 1.87 and 8 meters, and his basic height is fixed. According to the length of his legs of 100 meters and 46 steps, there is still a lot of room for optimization.

These days, Suzu has carefully watched his own running, as well as the previous European races, Tyson Gay and Asafa Powell's running.

In terms of the running skills of several people, Suzu and Tyson Gay's power skills on the balls of their feet are more than a cut worse than those of Asafa Powell.

Powell's football landing has a larger surface base, and although the foot and the ground contact time is longer than Tyson Gay, the same time in the air, stride distance, and make up for it.

Objectively speaking, there is no complete superiority or disadvantage in technology, the main thing is to suit itself, and Tyson Gay's current running skills also have a lot of room for improvement.

Increase the contact force between the back foot and the ground, and increase the stride length to about 44 steps. In addition, there is also the ability to react to the starting gun, and change his swing arm movement in detail, these are the technical points that Su Zu feels he can continue to polish when he has been training recently.

In addition to training and developing the explosive power and speed retention ability of the body, sprinting can improve the performance in detail, after all, sprinting is striving to improve with a score of 100 minutes and even 1000 seconds.

Su Zu now clearly felt that including the increase in potential value or the increase in attributes, the effect of improvement could hardly be directly reflected.

But if he encounters a big tournament and a strong enough opponent, he still has the potential to explode. Since there are still potential possibilities, it is also possible to make full use of all the current abilities of the body through better technology.

"Don't run yet." Li Zhizhong saw Su Zu walk on the starting gear on the side, stopped him, and turned to beckon to Zhang Peimeng, Wen Yongyi and Su Bingtian on the other side of the track and field.

"Director Li, what's wrong?"

Zhang Pingqiu, who came with the three of them, asked out loud.

He was just pointing out some routine warm-up movements for a few people before the game, which everyone has taught, but Su Bingtian has just arrived, and the national team's set is relatively more formal, and the body can be better opened in terms of action points.

"Su Zu has optimized his movements here, everyone will run with him and feel it." Li Zhizhong said with a smile, and then looked at Zhang Peimeng, Wen Yongyi and Su Bingtian, "You can also observe more by yourself during the run, from starting to accelerating, running on the way and the final sprint." ”

Before the starting line, Su Zu looked at a few people who were a little puzzled, smiled, and said, "I changed the running technique, please accompany me to run a few times." ”

A few people guessed what Su Zu was changing, and everyone didn't know much about it, but now when they heard Su Zu say this, they understood it.

After each of them took their places, several people leaned over the starting line at the same time.

The whistle sounded.

At the moment of starting, Su Zu and Wen Yongyi are not much different, after all, Wen Yongyi is the fastest person in China at present, and 60 meters is the fastest in China except for Su Zu.

Zhang Peimeng's starting speed has not been particularly ideal because of his height, and he is relatively longer than the second half.

And Su Bingtian, who is still relatively young and does not have a complete technical style, follows the set he used to teach at the sports school, which is more similar to a hurdler.

The four of them ran out together, and Su Zu was surprised to find that his speed in the first thirty meters was almost the same as Wen Yongyi's, slightly faster than Zhang Peimeng and Su Bingtian.

It was a distance of fifty meters on the track before gradually opening up the distance with the other three.

And when they crossed the finish line, the gap between the other three was not as big as they imagined.

Before the finish line, Li Zhizhong pressed the stopwatch time, saw Su Zu looking over, and reported the time on the stopwatch aloud, "9 seconds 95." ”

"9.95 seconds?"

Su Zu let out a sigh of relief, and his brows suddenly furrowed.

According to the stopwatch timing of a professional coach like Lao Li, the time recorded by hand must be controlled within 0.2 seconds. In this way, he only ran about 10.10 seconds at the fastest time this time.

"Just controlled at 44 steps?" Li Zhizhong asked after a deep sigh.

"43 steps more."

Su Zu recalled the stride at the last moment of crossing the finish line, and it was about half a step away from the finish line.

"It's not going to work in the short term, you have to at least start over and get used to your stride now and be as precise as possible. It is only after adapting to the new rhythm that it is possible to return to the original level, and as for breaking through again......"

Li Zhizhong did not continue when he said this, and the meaning of his words was already very clear.

Changing the pace of sprinting is a very difficult thing for athletes, and if Su Zu wants to break through again at his current level, even if he re-optimizes his movements, changing the pace may not necessarily lead to faster than he is now.

Su Zu actually knows that increasing and shortening the stride length is actually not an easy thing for an athlete who is used to a fixed stride length and cadence.

Whether each step is a little larger than the distance, or at the end of the sprint, unconsciously take a big stride, whether fast or slow is particular.

The feeling of his running down this trip can be said to be completely out of rhythm, and there are a few steps up in the middle of it, but in the last few steps, the stride length is not well controlled, and it comes down again.

Being able to change his stride length a few times in this run, and also ran a score equivalent to 10 seconds and 10 seconds in a click, is already because Su Zu is the current top 100-meter strength level.

But Su Zu also understands that he now has to think about optimizing his stride, which is often 45 and 46 steps, which is the mainstream step count for most sprinters today.

But compared to the 41 steps of the Jamaican lightning of later generations, he had to reduce his stride by one or two steps in order to form a strong competition.

With his height controlled at 43 and 44 steps, it is a number that is acceptable to his body and cadence.

It's hard to start reducing your steps in a short period of time, and it definitely takes a lot of time and effort.

Li Zhizhong knew every step of Su Zu's training well, and knew very well that Su Zu was a very assertive person early on. And after years of training and study, Su Zu's cognition of sprint training has also surpassed that of most athletes, and it is not much worse than a professional coach.

Even because he is an athlete, from a certain point of view, he understands things more clearly and thoroughly than a pure coach.

When it comes to training programs and intensity, only the athletes themselves know best. This is not noticeable in the early years of professional athletes, but by the middle and late stages of their careers, most people are able to complete their training programs well, even without a dedicated coach.

Most of the training plans that Li Zhizhong now assigned to Su Zu are actually just an open-faced plan, but in fact, the implementation and completion of the details are often based on Su Zu.

Zhang Peimeng and Su Bingtian, who were on the sidelines, watched Su Zu and Li Zhizhong discussing various training plans with each other, and their eyes were a little straight.

Zhang Peimeng is better, after all, he has been Su Zu's training partner, and he has also encountered situations where Su Zu and Li Zhizhong have different communication opinions.

And Su Bingtian didn't dare to imagine that the athlete was discussing the training plan with the coach, and it seemed that Li Zhizhong was still faintly based on Su Zu's opinion.

His training in the sports school was that the coach said to practice like this, practice like that, practice like that, practice like that, where do athletes have the right to speak. Even if the intensity is too high, the practice is injured or too tired to support it, there is no other way.

He is a teenager with a very good training attitude, strong execution, and will complete the training tasks assigned to him seriously, but he really hasn't thought about whether these training tasks are completely within the range of his body.

At this time, he somewhat understood what Zhang Pingqiu said, the meaning of athletes need to use their own brains to think.

This is not only a competition, but also in daily training, you need to learn and accumulate a variety of knowledge, and form a very systematic understanding of yourself.

Li Zhizhong and Su Zu occasionally popped up some English words in the chat, which broke his original cognition, and he and Su Zu were almost selected to enter the sports school in junior high school.

But now it seems that Su Zu's knowledge and understanding of kinematics far exceeded their imagination. Moreover, this coach Li Zhizhong is not at all as arbitrary as many coaches he knows.

Su Bingtian knew that even Coach Ning, who was very good to him in the sports school, would not allow him to question half a point when facing training tasks and training plans.

In fact, Su Zu himself didn't realize this, but when he embarked on the road of competitive sports, he was also blank.

One thing he does more than other teenagers of his age is that he knows how to be professional. Since the first time he entered the national team youth training, he listened to lectures to learn various physical education, sports human science, sports training, etc., and practiced while studying over the years, and unconsciously mastered the training experience and skills that he mastered, in fact, no less than others.

And because he is an athlete, he can personally verify it, and he absorbs a lot of useful or suitable for himself, and the whole cognition gradually surpasses many people.

Like Li Zhizhong's cross-training water running, Su Zu still followed the training method Li Zhizhong said at first, but after a few times, Su Zu actually gradually found the most suitable training method for himself.

Whether it's stepping in the water or adding a few dumbbells for intensive arm swing training, Su Zu is moving in a direction that suits his own situation.

Li Zhizhong understands that an athlete who is talented and knows how to think will inevitably be brilliant if his career does not suffer major injuries.

And even if this athlete has average talent and has not achieved particularly good results in his career, if he has really thought deeply, from training to competition, combined with the perspective of an athlete and a coach, he will often be able to quickly rise to prominence and become a top excellent coach after he enters the coaching industry.
