Ersha Island.
"So, if your latest training system is restored again, do you have to adopt this mechanics model?" Zhao Haohuan asked when he heard this. Seeing Su Shen nodding, he could only admire him many times: "I used myself as the 'test product' of the latest scientific research theory. Grandpa Tian, ​​tell me, who else is the same as you?"
"Everyone is either waiting and watching or avoiding things first. Before stability, who dares to use themselves as a 'test product'? No ordinary people don't know, let alone track and field, our career is very precious."
"Who is not?" Su Shen smiled while warming up: "It's all the same, and if it's me, the success rate is higher, right?"
"I'll give you some examples, I believe this will be more credible."
"You are really addicted to being a guinea pig." Zhao Haohuan could only say helplessly: "However, I really admire a person like you from the bottom of my heart. If it weren't for our relationship, there would be no need to be too exaggerated. I really want to salute you for everyone."
"Okay, you, when you stop stagnating in the future, you need to change your technology, and when you ask me for it." Su Shen laughed. He didn't want to be too serious, because his prestige on Ersha Island was already high enough, and if he continued, he would probably be deified.
If that is too much, it is 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 game will change rapidly and the "butterfly effect" will become increasingly greater in the future, and I will gradually become less and less able to help them make "accurate predictions".
Therefore, it depends on your own.
He doesn't want these people, he depends entirely on him.
"What's that?" Zhao Haohuan looked like "a dead pig is not afraid of boiling water". He didn't pay attention to his image anyway: "Anyway, I've heard you, Professor Su preaching and learning, and he has not answered his doubts once or twice."
"I've long been used to the feeling of your brain being dominated by you."
"Uh." Su Shen looked at Zhao Haohuan like this and said in a daze: "Gouhuan, you really look like Abing like this. Have you been infected by him?"
"Sometimes." Zhao Haohuan did not object, and said, "It's good to learn pancakes."
"I want to tell him this, he will definitely die of pride."
"Hey hey hey, what's going on? Isn't this a private chat channel between us? How can it be spread? You can't help but tell me Xiaotian!" When he heard that he was about to tell Zhou Bing, Zhao Haohuan was immediately anxious and almost jumped.
"But is this thing OK for us, a player like the back-end? I remember that my skills were divided by you and were more inclined to the back." Zhao Haohuan asked after a few fusses. For him, talent is one aspect to be able to continue to break through and get here, but it is more of the "guidelines" of Su Shen, constantly pointing him to the right path.
Even the latter is even more important.
Because at this stage.
It can be said that any opponent is talented.
Those who have no talent cannot reach this level.
Therefore, compared with this, it is actually meaningless. So comparing the following elements is the key to whether you can go further.
"Don't worry, front side mechanics is suitable for all running modes, and as I said, even for front side technology, you must practice back side technology well, and for back side technology, you must practice front side technology well, so that the ratio can be faster, rather than letting one side become unbalanced, that is wrong."
Many people think that front-side technology means giving up the back-side, and back-side technology means giving up the front-side. This is a stupid statement.
Ralph Mann's mechanics work is very clear. Use a diagonal line to divide it. If it is more in front, it is the front side, and if it is more in back, it is the back side. However, it is impossible for you to go all your body to the front, so you can't run at all.
So the ratio between 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 immediately." Zhao Haohuan felt a lot more comfortable when he heard this, because it seemed that if he couldn't train this latest theory, it would be... a bit regrettable.
...
It is approaching November, and he has not received any trouble with the outside world about Su Shen's status.
On the contrary, I focused on training with Randy every day, or I would build and perfect the final front-side mechanics theory with Ralph Mann.
“It’s really…amazing.”
"Your first three steps now feel better and better. The torso leans forward angle, the first step is instant forward angle, the second step is instant forward angle, the third step is instant forward angle, the third step is instant forward angle, the instant forward angle are obviously close to good, but it may be that the gluteus maximus muscles are insufficient muscle strength and the dorsiflexion stability is insufficient, which has not reached the excellent level."
"It's okay, just make progress. Your body is still recovering and you can meet the task goals." Su Shen thought, "Help me see my acceleration zone, Randy."
"Is this accelerator zone a little faster?" Randy said in surprise: "Although you have completed the three golden steps in half a month, you have just begun. Should you consolidate it?"
"No need." Su Shen shook his head and said, "Or it would be too late. Moreover, I have already done exercise imagination in my mind many times before. Besides, I will have to retrain the combination later. I will go through it first and quickly return to within 11 seconds. Otherwise, it will be too slow. At that time, after the second stage of the inspection, even before the New Year, I will at least give an explanation."
"Okay, how are you going to get to the acceleration zone?"
"Let me see from these aspects." Su Shen said to Randy on the computer: "Look at the body posture, look at the movement trajectory, look at the movement time, look at the speed and rate of the movement, and then look at the power feedback on the sensor. Finally, the most important point, rhythm issue."
"Let's take a look at these seven basic points first."
bang, bang, bang, bang, bang, bang, bang.
This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! Bang, bang, bang, bang, bang, bang.
After running a few groups, Su Shen walked over to see how Randy's data collection was.
"Body posture evaluation: Bad, obvious connection problems, accelerated center of gravity problem, unstable overall structure, and there is no symmetry in the legs that step out..."
"Evaluation of action trajectory: Bad, all movements have obvious sense of powerlessness."
"Movement time: bad, the degree of disorder is very good, and the time difference between them is very large, which does not conform to the optimal acceleration model for the human body."
"The speed and rate of movement: Generally, if you want to do it well, but because of physical reasons, you cannot keep up with the force, which leads to a slower movement rate."
"Movement power feedback: poor, the strength of touching and pushing the ground is unbalanced, the rear pedal is insufficient, and the strength continues to be poor."
"The rhythm of action: extremely poor, the whole rhythm is messy, not like an elite athlete at all, but more like a guy who just learned to run."
After reading this, Su Shen usually complains about the text developers of this machine, but they are really a bit "language art". Lu Shuren calls him an expert.
But besides these...
The rest of the statements are quite accurate. You can use a machine to do a preliminary assessment of your own problems.
Save a lot of time on coaches and coaching teams.
The entire evaluation system is also good, the worst is the movement rhythm, which is also the core problem that will arise after changing feet.
All the original rhythm was abandoned, and the new rhythm had not been established yet, so it was naturally a mess.
This shows that my current muscle state is a little weaker and cannot adapt to this new technology and new rhythm well.
After reading these basic acceleration zone evaluations, Randy greeted Su Shen a few times and asked him to come over to look at the computer screen on the other side and said: "The change trend of the center of gravity velocity and the horizontal forward component of the center of gravity velocity is very similar. The two are almost equal at the beginning stage, and the difference between the two is not too big even in the latter stage. The starting speed is poor, that is, the torso is lifted too early."
The changes in the center of gravity velocity of 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 of jumping to step 4, there are 4 peaks and 4 troughs, and the upper body is rising up with the rise of the upper body."
The change curve of knee joint angle over time at this stage of 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 your speed, the horizontal forward speed, and the vertical speed are not enough to control. Compared with the previous model, there is a big gap. The lack of core muscle groups may be the key."
"Secondly, you accelerate your hip angle, angle between the torso and thigh, angular velocity, flexion and hip extension speed are not good, the rhythm problem is very big, and the connection is not done well."
"At the same time, I think there is also here. The angle between the knee joint angle, hip, knee connection line and knee, ankle connection line, angular velocity, flexion, knee extension speed, magnitude of speed, horizontal forward speed, vertical speed, and displacement in the vertical direction are all very lacking, especially your knee joint angle, which does not conform to the mechanical model at all, which directly leads to your back lifting too high and reduces your acceleration."
"Then the angle of your ankle joint, the angle between the knee, ankle connection line and the ankle, the speed of flexion, the magnitude of the ankle extension, and the displacement of the velocity in the vertical direction are not enough, especially the displacement of the ankle joint in the vertical direction is not enough. This may be caused by the power chain that cannot be connected after you change your feet, and the force line drifts."
"These all lead to your acceleration running, your movements are not coordinated enough, your connection is stiff, and even the torque offsets between each other."
"I think this is because the first few steps of the MI acceleration run may want to obtain more sufficient rear pedal force, which will lead to a smaller rear pedal angle through a lower center of gravity. However, because your upper body is seriously leaning forward at this time, and the swinging legs have to be fully opened, and you enter the support stage. Therefore, when the swinging legs hit the ground, the knee joint angle is already small, which is not conducive to the transmission and continuation of force."
"On the other hand, you need to whip the support leg to obtain the back pedal force needed to accelerate the body, but now you are not strong enough. Forced back pedaling action will cause the knee joint angle when you kick off the ground. If you enter directly on the way, it is very likely that your extreme speed will not be able to get up at all, affecting the entire back 70 meters."
"What is the projection point of the foot when running in?" Su Shen asked.
"Well, let's see." Randy said after searching for it, "It's less than 20CM. Generally speaking, high-level athletes must reach the range of at least 27~37CM."
"The rhythm after changing the foot is completely messy and needs to be rebuilt. The body muscles have stopped practicing for a long time because they wanted to completely forget their muscle memory some time ago. Now they pick it up quickly, but it also takes time." Su Shen touched his chin and said, "The first level of the sports performance pyramid: core control, flexibility and stability are not done well, which really affects the subsequent training performance."
"Of course, Sue." Randy said when she heard this: "The movement is done by the limbs. We use the limbs to touch objects and complete the little things in life, so we think that the movement begins with the limbs. This view is actually wrong. Each movement should start at the center of our body, that is, the core area of ​​the body. The torso is also called the pillar, which is the center of life and movement, and is also the basis of movement. It mainly includes the hip joint, the torso and the shoulder joint. Among them, the hip joint is the largest link. If you don't do these well, the hip will naturally be insufficient. There are many problems in the acceleration area and the speed cannot be improved."
This chapter is not over, please click on the next page to continue reading! "If the human body is compared to a wheel, then the body is the axis and the limbs are as the axis. As long as the wheel axes are aligned, the force can be evenly transported to all parts of the body. As the saying goes, the center of gravity is stable and the limbs are flexible."
"You should do this basic action layer first. Sending the hip is to accelerate, and even the core of the entire sprint. It takes a lot of time to master this after changing feet. Even if you just do it again and have experience, it will probably take a long time."
"Yes, there is no way to do this. No one is a genius and cannot be achieved overnight." Su Shen thought for a while and said, "In addition, there are so many technical aspects that need to be embedded in this new running rhythm. Some of them are busy before the New Year this year."
"I'm afraid there's no time to go back during the Chinese New Year, Randy."
"I don't care. We only celebrate Christmas. The New Year is a festival for you orientals, but we Americans." Randy shrugged and said Americanly: "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 pay you overtime salary, I will definitely increase the money."
Randy was stunned and laughed and said, "What I originally wanted to say is that the Chinese New Year is very important to you orientals. Is it really good not to go back? But since you said that you have added money, I won't refuse."
"After all, I have received overtime pay. If I don't help you well, I will feel uneasy, Su."
"Okay, in order to make your conscience less stable, you have to add money, so that you have to work hard with me."
"No problem, the money is in place, we Americans can say anything."
The two of them made a few jokes and then went into intense training.
On the other hand, Su Shen had expectations for his acceleration zone.
If it really develops as you expected.
Waiting to London next year, you can fully stimulate and adjust the winter training status.
That's when the world really shocks.
It's the process...
Very painful.
Very boring.
PS: The second update is here, you can also sniff it, hehe, I will continue to have a date tomorrow, big guys~~~~~~~~~~!!!!!!!!!!!!!!!!!!!
