Somehow, there was a storm outside about Su Shen.

I don’t know who leaked the news. Now it’s all discussed whether Su Shen’s technical reform failed and it’s completely impossible.

Some people even have noses and eyes, saying that Su Shen lost to the female athlete.

Of course, many people don’t believe this, because it is certain that the decline in strength is certain, but if you lose to a female athlete, that’s different. Normal people will think that this is impossible.

So because of this "increasing fuel and firing" word, this matter has become somewhat unbelieveable by everyone.

At least most people choose to stand on Su Shen’s side.

Ershadao Su Shen is making his own technical changes after foot change with Randy, and he will chat a few times when he has time.

"Someone actually leaked this news, which has never happened before." Randy said: "Isn't this confidentiality not to be known?"

"It was before." Su Shen didn't think there was anything too strange. He was too many people and talkative, and the people from above were obviously "outsiders", but they were just assigned to this job.

It’s hard to say how much love and faith there is here.

"We were not the only one here that day."

"But weren't they sent from the higher authorities?" Randy was puzzled.

"The meaning above is hard to fully understand. And if I have a good effect, I may strengthen confidentiality. If the effect is very poor, it is hard to say." Su Shen didn't want to continue this topic. He knew that athletes still had to speak with their grades, so the topic returned to the side of technical changes and said, "Have my startup posture been set?"

"Well, the new version is out, but as you increase your muscles again and increase your muscle content, you may have to change it." As soon as Randy talked about professional things, she quickly got into the state and clicked the mouse and said, "This is your torso measurement, you can see."

Su Shen leaned over and looked at the data model on the screen, which said that the angle between his torso and horizontal line was at a negative octave.

"I remember the best one should be around 0 to minus twenty degrees, which means my body is not able to load a better trunk forward angle."

"That's right." Randy looked at the screen, clicked the mouse, and a new page immediately popped up on the screen: "This is because you have been resting for so long now, and the entire strength cannot be exerted and output after changing feet, so that your torso will not be too good to lean forward."

"So now I think this angle is your current load angle. As your body recovers and trains, this angle will also be readjusted and changed."

"Where is the torso angle forward when you kick off the starting device?" Su Shen looked at the model on the screen and continued to ask.

"What do you think of the plan I proposed? "Sir Ralph Mann?" After Su Shen said, Randy smiled and said, "That guy seemed to have been pointed out by you all at once. He soon dived into and studied it. He was very concerned about the exercise mechanics book you made with him."

"If you didn't want him to take Liu Jian, I would have doubted..."

"He has no intention of doing anything else now."

Ralph Mann had a classic short-span mechanics released in his previous life, which was also the guidance of many athletes and sports institutions in the future. On this timeline, Su Shen will complete it with Ralph Mann. He will also fill in the sports concept of the former, and add some ideas in the next few decades to make it more advanced.

"But, you two are really brave enough to change the four steps of gold to three steps of gold?"

Randy said this, and she slammed her mouth a few times, as if she thought it was something

"Although I have heard people do this before, it is all about experience, and none of them is guided by a theoretical system."

"When I heard it, I was really a little bit and didn't react."

"After all, Mr. Randy, you are still more inclined to coach, and Ralph is good at scientific research." Su Shen smiled and said, "And you have also said that in fact, some people have discovered the disadvantages of the four-step golden step, which is increasingly mismatched with the current sprint system. Some keen coaches have also begun their own reforms. This shows that there has actually been an opportunity for change, but someone still needs to give it a shot."

"It's easy to say, but it's the hardest to sum it up into scientific theories." Randy thought of the thing they were studying, but she didn't withdraw from thinking for a long time. She kept researching it, thinking about how to use such things on athletes.

It may take a long time to just accept someone, but if it is Su Shen, this problem will definitely be solved soon.

Because this thing was originally proposed by them, isn't it?

Maybe they need them to teach themselves.

"If it is improved, it will be a big technological revolution for the entire industry." Randy said: "No less than now more and more people are starting to do the eight-change and seven-span in the short span. Technology is always improving."

"Then look at your first step and the moment of tilt forward angle is currently 60 degrees. According to your golden three-step rule, if you want to do this well, it is best to be within forty-eight degrees, or at least fifty-three degrees before you can complete the next few steps."

"If you can, look at your three-dimensional model. Y is better than 85, and the rest is better than 80."

"Then it's the angle of your calves and thighs." Randy said: "Because you changed the starting foot, your angle is a little small now. After changing the starting foot, your physical strength explodes and the pedals changed. If the excellence is at 90 degrees, you are only 80 degrees now, and the angles of your front and back feet are also very different from the three golden steps you have made, but you have just started changing your feet, and I guess you will recover a lot later."

This chapter is not over, please click on the next page to continue reading! "I recommend that the angle of your knee joint in the rear leg should be changed. It will be better to open a little backward. It will be easier to give you strength. Your current strength is not close enough to this number."

"Well, I know." Su Shen nodded after looking at it. He agreed with Randy's opinion. His body rhythm and sense of force have changed. In addition, in order to completely forget the previous muscle memory some time ago, the muscle strength is not as strong as before. So now we can adjust it first.

"Then let's talk about the most critical points you want to change to the three golden steps. One is the angle between the calf and the thigh when you kick the hind leg off the starting device. In the previous four-step setting, the angle between the torso and the thigh is about 90-110. When you kick the thigh, the stretching range of the thigh is not large, and the process of increasing the angle between the upper body and the thigh is relatively long. Therefore, the inner femoral muscle is the first muscle to stretch the calf. When stretching the knee in a relatively static state, the muscle contraction range will be limited to a certain extent." Randy looked at the newly made three-dimensional model and said: "Now your method requires the angle between the calf and the thigh in the first step. At the same time, it is necessary to avoid further expansion of this angle to avoid affecting subsequent force."

"Otherwise, it will cause small amplitude of the inner femoral muscle, which will have a great impact on the use of three-dimensional power in the starting stage of the sprint and subsequent steps. Look at this set of data." Randy pushed the computer to Su Shen's eyes and clicked on a page and said: "This is your previous four-step start. This is the next three-step start model you speculated. The average net generation amplitude between the former and the latter may not be different, but in the starting stage, the sagittal vector of the latter is obviously tilted forward than the former. In contrast, in the starting stage and subsequent steps, the latter three-step start will cause the whole body's front and back acceleration and the inner acceleration to point more forward. Therefore, the more forward-tilted vector and a larger front-back direction may affect the latter's sprinters producing an average front-back blocking acceleration between the sprinters who start in the former way."

"I just don't know how to use this more forward-tilted vector in actual combat."

"And this fluctuation of about ten degrees has always existed, and I am a little confused."

"There is another problem with three-step startup, which is that it is easy to over-punch and protrude, and it is easy to have too much air time, which will undoubtedly greatly slow down the effect of four-change and three."

Randy is also the first time to come into contact with this new startup mode, which is no less than the first proposal to propose a short span of eight to seven.

Therefore, he, the famous track and field coach, was somewhat stumped.

Although he can also give him time to think and solve it slowly, Su Shen is very clear now that there is no time to wait, so he directly said the answer:

We should not worry about these ten-degree fluctuations.

I think this problem can be avoided by actively pulling your ankles forward.

Not only can it reduce over-pushing, but it can also reduce the airflow time due to over-pushing.

"Is this really possible?" Randy was stunned. He had never expected that the problem he had been struggling with for so long. Su Shen explained it in one sentence and proposed a clear solution.

"What about the excessive swing time of the swing legs in the air after changing to three-step start?"

After hearing this, Su Shen said without thinking: "Just use my latest 'semi-credit card' to land, and solve this problem."

"Half, half credit card?" Randy was stunned. After he came to Ersha Island, he could always hear some new terms from Su Shen that he had never heard of before.

"It's just a tentative decision." Su Shen explained: "Because this will be thinner than the far-reaching credit card technology, and it will reduce the floor space, or it can be called paper flooring technology."

"Because as long as the operation is good enough, it can be thinner than the credit card landing technology and is more conducive to shortening the touchdown time."

"That is to say..." Randy suddenly thought of something and said: "Originally, the ankle dorsiflexion of the foot before it landed. The biggest pursuit was to sprint the ankle dorsiflexion of the foot. The gap between the heel and the track when the foot landed, and could only be stuffed into a credit card. Now it has become a piece of paper. With just a little change, the accumulation of less will eventually affect the 100-meter race based on 0.01 seconds."

"It's not just that." Su Shen said: "If it succeeds, it can further improve the limit of the pace frequency. Just like credit card technology can further upgrade everyone's pace frequency and open up the original constraints. The same is true for this technology, because this can further shorten the touch time, so that is to say... "

"Your pace frequency is impossible without increasing it."

"You are such a...monster."

"It's not just that, our laboratory also conducted a test, using two-dimensional coordinate data to derive the sagittal joint angle curve of the sprint test. The continuous relative phase (CRP) analysis method was used to detect joint coupling movements in the limb. The knee-ankle (KA) coupling was less coordinated with hip-knee (HK) coupling in the stride stage (average CRP: KA 89.9° HK 34.2°), and produced lower intra-athlete CRP variability (VCRP) when stanced. Touching ground (TD) produced more inverse phase movement and greater VCRP than toe ground... That is, the instability of the lower limb coordination pattern is considered necessary, and doing so can reduce this instability as much as possible and further increase the coordination pattern of the lower limbs."

"That's the case..."

Before Su Shen finished speaking, Randy continued: "In this way, your original lower limb pattern can further increase the advantageousness of the necessary adjustment mode instability, that is to say..."

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! "The upper limit of lower limb mode movement will also be further improved to break through the bottleneck, right?"

"Bingo." Su Shen snapped his fingers and said, "In this way, my rhythm will have more potential and more possibilities."

"My original rhythm system and motion system cannot adapt to these latest technical concepts, so in order to improve myself and adapt to these conceptual technologies, I also have to change my feet and reconstruct it."

Randy:...

Hearing this, he originally thought that Su Shen was a "monster", but now he can only say...

This guy is a "monster".

Because of one problem, he can solve it while solving several problems with obvious gain effects at the same time.

Is this still a human???

Maybe Randy felt a little worried when she saw Su Shen’s martial arts wasted, now...

He felt that if there was someone in this world who could succeed in "repeating the practice of scattering the merits" like this.

That must be Su Shen.

It must be this young man whose brain has been shined by Jesus.

Whenever I think of this, Randy seems to feel like...

Every time I get stuck, I feel like the young man in front of me will easily reveal it.

Forget it once or twice.

You can say that it was a flash of inspiration, but it was like this every time.

Randy almost thought that this guy was "all-knowing and omnipotent" and had he been ready to "answer your own questions and answer questions" long ago.

This kind of "arrangement".

It made him feel that his mind was not enough.

"Is there any other problem, Mr. Randy?" Su Shen looked at Randy, who was still in a daze.

"Forehead."

Randy was stunned.

"there is none left."

He complained in his heart:

Even if there is.

I guess you have thought of a way to do it.

Anyway, you're the same as Ralph.

They are all scientific researchers and athletes.

We don't understand this either.

We won't ask anymore.

"Then start the golden three-step training class."

"Try to get it done for him in a month."

Randy, who had recovered a little and was about to look at the training plan, almost staggered by this.

"One, one month? This is a new technology, a brand new thing. In addition, you still have to reconstruct your own pyramid of sports performance and need to continue to modify the technical details as your body recovers. Can you...you can do it in half a month?"

"Is this time..."

"Yeah." After hearing this, Su Shen nodded and said, "I think it's too long, so let's fight..."

Su Shen thought for a while and said seriously: "Then let's finish it in half a month."

"There is still a lot of things to be done behind it."

"It's true that there's not enough time."

"After all, this is just a start, it's not a core change, right? I don't have time to allocate more to him."

"Half a month is enough."

Randy:???

Randy:!!!

Randy:...

PS: The Golden Three Steps is a theoretical concept proposed by Ralph Mann in his 2011 short-span mechanics work. Compared with our previous four steps, it is indeed a bit like "four changes to three".

Technical transformation is a bit difficult to write, I will do my best.
