The Su God of the Reopening of the Sports Arena

Ersha Island.

"So your latest training system, when you start to recover again, will adopt this mechanical model?" Zhao Haohuan asked after hearing this. When Su Shen nodded, he could only praise him countless times: "Again Using yourself as a 'guinea pig' for the latest scientific research theories, Master Tian, ​​tell me, is there anyone else who is like you?"

"Everyone is either waiting and watching or avoiding new things. Before there is stability, who dares to use themselves as a 'guinea pig'? Ordinary people can't do it, let alone in track and field, our careers are very precious. Yes."

"Who is sure?" Su Shen was warming up and said with a smile, "It's all the same, and if it were me, the success rate would be higher, right?"

"I believe it will be more credible if I give you a sample."

"You are really addicted to being a guinea pig." Zhao Haohuan could only say helplessly: "However, I really admire people like you. If it weren't for our relationship, there is really no need to be exaggerated. I really want to help you for everyone. Salute."

"Okay, you, when you stagnate in the future and need to change your skills, you can ask me for help." Su Shen laughed and said. He didn't want to take it too seriously because of his prestige on Ersha Island. It's already high enough. If you go down any higher, you'll probably become a god.

That's too much, and it's not a good thing for the development of the entire Ersha Island.

An excellent athlete must still have a certain degree of self-analysis ability.

Otherwise, the competition will change rapidly, and the "butterfly effect" will become larger and larger in the future, and I will gradually be less and less able to help them make "accurate predictions."

So when the time comes, it still depends on yourself.

He doesn't want these people to be completely dependent on him.

"What's the point?" Zhao Haohuan looked like a "dead pig not afraid of boiling water" in front of Su Shen. Anyway, he didn't pay attention to his image and said: "Anyway, I don't listen to Professor Su once or twice."

"I have long been accustomed to the feeling of having my mind controlled by you."

"Uh." Su Shen looked at Zhao Haohuan like this, and said for a moment, "Gou Huan, you really look like a soldier like this. Have you been infected by him?"

"Sometimes." Zhao Haohuan didn't object here and said, "It's good to learn how to make pancakes."

"If I tell him this, he will definitely die of pride."

"Hey, hey, what's going on? Isn't this a private chat channel between the two of us? How could it be spread out? You have to be honest, Xiao Tian!" When he heard that he was going to tell Zhou Bing, Zhao Haohuan immediately became anxious and almost jumped. .

"But is this thing okay for late-range players like us? I remember you classified my skills as more towards the back." Zhao Haohuan asked again after a few moments of fuss. For him, being able to continuously break through and get here, Talent is one aspect, but more of it is Su Shen, the "guiding light" who constantly points him to the right path.

Even the latter is more important.

Because it’s at this stage.

It can be said that every opponent is talented.

Those without talent cannot reach this level.

Therefore, compared with this, there is actually not much meaning, so comparing the following elements is the key to whether you can go further.

"Don't worry, front side mechanics are suitable for all running modes. And as I said, even if you are doing front side technique, you must practice the rear side technique well, and you must also practice the rear side technique well at the end of the front side technique, so that the ratio can be faster. Instead of unbalancing one side, that would be wrong.”

Many people think that front-side technology means giving up the back side, and rear-side technology means giving up the front side. This is a stupid statement.

Ralph Mann's mechanics work makes it very clear. It is divided by a diagonal line. The front side is the front side, and the rear side is the back side. However, it is impossible for your whole body to go to the front. Can't run.

So the ratio of front and back is just to see which side you focus more on, rather than giving up on one side.

"That's good. If I reach a bottleneck, I will learn from you right away." Zhao Haohuan felt a lot more comfortable when he heard this, because in his opinion, if he couldn't train this latest theory, it would be really bad. ...What a pity.

……

Now that November is approaching, he is not bothered by questions about Su Shen's status from the outside world.

Instead, I focus on training with Randy every day, or construct and perfect the final frontal mechanics theory with Ralph Mann.

"It's...amazing."

"Your first three steps now feel better and better. The forward tilt angle of the trunk, the forward tilt angle at the moment of pedaling off in the first step, the forward tilt angle at the moment of pedaling off in the second step, and the forward tilt angle at the moment of pedaling off in the third step are all starting to be obviously close to good, but It may be that the muscle strength of the gluteus maximus is insufficient and the dorsiflexion stability of the foot is insufficient, which leads to the fact that it has not reached an excellent level."

"It's okay. Just make progress. Your body is still recovering after all. Just meet the mission goals." Su Shen pondered: "Help me check my acceleration zone, Randy."

"Isn't the acceleration zone a bit fast?" Randy asked in surprise: "Although you have completed the three golden steps to a good level in half a month, you have just started after all. Do you want to consolidate it?"

"No need." Su Shen shook his head and said: "Otherwise, I won't be able to make up the time, and I have done motor imagery many times in my mind before. Besides, I have to retrain the combination later. I will go through it first and quickly return to 11 seconds. Within, otherwise it is indeed too slow. When the second phase of inspection is completed, even before the Chinese New Year, I will have to give an explanation."

"Okay, how do you plan to get to the acceleration area?"

"Help me take a look at these aspects." Su Shen said to Randy on the computer side: "Look at the body posture, look at the movement trajectory, look at the movement time, and then look at the speed and rate of the movement. , and then look at the force feedback on the sensor side, and finally the most important point, the rhythm issue."

“Let’s take a look at these seven basic points first.”

Bang, bang, bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang, bang, bang.

After running a few groups, Su Shen walked over to see how Randy's data collection was going.

"Evaluation of body posture: Poor, there are obvious connection problems, the center of gravity of acceleration is erratic, the entire structure is unstable, and the legs are not symmetrical..."

"Action trajectory evaluation: Bad, all movements have a clear sense of powerlessness."

"Action time: bad, the degree of disorder is very good, the respective times are very different, and it does not conform to the optimal acceleration model of the human body."

"Speed ​​and rate of movement: average. I want to do well, but due to physical reasons, my force cannot keep up, resulting in slow movement speed." "Strength feedback of movement: poor, the strength of touching the ground and pushing off the ground is unbalanced, and the back kicking Insufficient, consistently poor strength.”

"Rhythm of action: extremely poor. The whole rhythm is messed up. He doesn't look like an elite athlete at all, more like a guy who has just learned to run."

After Su Shen read it, he usually complained about the text developers of this machine, but he really had some "language arts", and everyone in Lu Shu called him an expert.

But apart from these...

The rest of the statements are fairly accurate. You can use a machine to do a preliminary assessment of your own problems.

Saves coaches and coaching teams a lot of time.

The entire evaluation system is also good. The worst thing is the rhythm of the movements. This is also the core problem that will arise after changing feet.

The original rhythm has all been abandoned, and the new rhythm has not been established at all, so it is naturally a mess.

It explained that my current muscle condition is a little weak and cannot adapt well to this new technology and new rhythm.

After reading these basic acceleration zone evaluations, Randy called to Su Shen a few times, asked him to come over and look at the computer screen on the other side and said: "The changing trends of the center of gravity velocity and the horizontal forward component of the center of gravity velocity are very similar. In the beginning, The two are almost equal, and even in the latter section the difference between the two is not too big. The use of starting speed is poor, that is, the trunk is lifted too early.”

The center of gravity speed changes in the first ten steps are as follows: 5.99 6.23 6.18 6.13 5.77 6.11 6.41 6.57……

"In the process from taking off to the fourth step of pushing off the ground, along with the body's soaring and the vertical displacement of the center of gravity, there are 4 peaks and 4 troughs, which continue to rise as the upper body rises."

The change curve of knee joint angle with time at this stage on the ground: 0.35 0.27 0.35 0.32 0.26 0.34 0.36 0.35……

"I think the displacement of your center of gravity in the vertical direction, the magnitude of the speed, the horizontal forward speed, and the vertical speed are not controlled enough. Compared with the previous model, there is a big gap. The lack of core muscles may be the key."

"Secondly, when you accelerate running, the hip joint angle, the angle between the trunk and the thigh, the angular velocity, and the speed of hip flexion and extension are not good. There are big rhythm problems and the connection is not in place."

"At the same time, I think there is another thing here. The several sets of accelerating runs you just did, the knee joint angle, the angle between the line connecting the hip and knee and the line connecting the knee and ankle, the angular velocity, the speed of knee flexion and extension, the magnitude of the speed, and the horizontal direction. The front speed, vertical speed, and displacement in the vertical direction are all lacking, especially your knee joint angle, which is completely inconsistent with the mechanical model, which directly causes your rear kick to be too high and reduces your acceleration."

"Then your ankle joint angle, the angle between the line connecting the knee and ankle and the line connecting the ankle and toe joints, the speed of ankle flexion and extension, the magnitude of the speed, and the displacement in the vertical direction are all insufficient, especially the ankle joint. The displacement in the vertical direction is not enough. This may be because the power chain cannot be connected after you change feet, and the force line drifts."

"These all lead to uncoordinated movements in your acceleration, stiff connection, and even mutual torque cancellation."

"I think this is because in the first few steps of accelerating, you may want to obtain a relatively sufficient back pedaling force, which leads to a lower center of gravity to obtain a smaller back pedaling angle, but at this time your upper body is seriously When forward leaning occurs, the swinging leg enters the support stage before the lower leg can be fully opened, so the angle of the knee joint is already small when the swinging leg lands on the ground, which is not conducive to the conduction and continuation of force. "

"On the other hand, the supporting leg needs to actively push back in a whipping manner to obtain the back pushing force needed to accelerate the body. But now that you are not strong enough, forcing such a back kick will cause the knee joint angle to be larger when kicking off the ground than when running. Too much. If you run directly into the middle of the road like this, it is very likely that your top speed will not be able to rise at all, affecting the entire next 70 meters."

"How far is the landing point of the foot from the projection point of the total center of gravity when running in?" Su Shen asked.

"Well, let me take a look." Randy looked for it and said, "It's less than 20cm. Generally speaking, high-level athletes must at least reach the range of 27~37cm."

"After changing feet, the rhythm was completely messed up and needs to be rebuilt. The muscles of the body also stopped practicing for a long time because I wanted to completely forget the muscle memory some time ago. Although it is quick to pick up again now, it also takes time." Su Shen touched it. He said with his chin: "The first level of the sports performance pyramid: core control, flexibility and stability are not done well, which will indeed affect subsequent training performance."

"Of course, Sue." Randy said after hearing this: "Actions are completed by the limbs. We use our limbs to contact objects and complete everything in life, so we think that actions begin with our limbs. This view is actually wrong. Every action should It starts from the center of our body, that is, the core area of ​​the body. The trunk, also called the pillar, is the center of life and movement and the basis of movement. It mainly includes the hip joint, trunk and shoulder joint. The hip joint is the largest link. , if you don’t do this well, the hip thrust will naturally be insufficient, there will naturally be many problems in the acceleration zone, and the speed will not increase.”

"If the human body is compared to a wheel, the body is the axis and the limbs are the axis. As long as the wheel axes are aligned, the force can be evenly transmitted to all parts of the body. As the saying goes, a stable center of gravity and flexible limbs."

"You should do this basic movement layer first. The hip movement is acceleration, and it is even the core of the entire sprint. It will take a lot of time to master this again after changing feet. Even if you just do it again, with experience, I'm afraid Yes, it will take a long time.”

"Yes, there is no way in this regard. No one is a genius and cannot be achieved overnight." Su Shen thought for a while and then said: "In addition, there are so many technical aspects that need to be embedded in this new running rhythm. Before the Chinese New Year this year, some people will be very busy.”

"I'm afraid I won't have time to go back during the Chinese New Year, Randy."

"I don't care. We only celebrate Christmas. Chinese New Year is a holiday for you Easterners, not us Americans." Randy shrugged and said in an American style: "So if you need to stay, I don't care. It's not a big problem. .”

"but……"

Before Randy finished speaking, Su Shen smiled and said: "Don't worry, I will definitely pay you overtime wages, and I will definitely increase the money."

Randy was stunned for a moment, then laughed and said: "What I originally wanted to say was that the Chinese New Year is very important to you Orientals, so is it really okay not to go back? But since you mentioned adding money, I won't refuse. .”

"After all, I have received overtime pay. If I don't help you properly, I will feel guilty, Su."

"Okay, in order to prevent your conscience from settling so easily, I have to add more money so that you have to fight with me."

"No problem, as long as the money is in place, we Americans can say anything."

The two made some jokes and got back into intense training.

Su Shen, on his side, has expectations for his own acceleration zone.

If it really develops as expected.

Wait until London next year to fully stimulate and bring out the state of winter training.

That's when it really shocked the world.

It's the process...

Quite painful.

Quite boring.
