The Su God of the Reopening of the Sports Arena

There has been a storm outside about Su Shen for some reason.

I don’t know who leaked the news, but now everyone is discussing whether Su Shen failed in his technical transformation and is completely dead.

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

Of course, many people don't believe this, because the decline in strength is certain, but losing to a female athlete is different. Normal people will think that this is impossible.

So just because of this "adding fuel and jealousy", it actually makes this matter somewhat untrustworthy by everyone.

At least most people chose to side with Su Shen.

Ershadao Su Shen and Randy were making technical changes after changing their feet, and they had some time to chat.

"Someone actually leaked this news, which has never happened before." Randy said: "Isn't this a secret to prevent others from knowing?"

"It was before." Su Shen didn't think there was anything too strange. There were so many people talking, and the people above seemed to be "laymen" at first glance. They just happened to be assigned to this job.

It’s hard to say how much love and belief there is on this side.

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

"But weren't they sent from above?" Randy was puzzled.

"It's hard to say that I fully understand the meaning above. And if the effect is good, I may tighten the confidentiality. If the effect is bad, it's really hard to say." Su Shen doesn't want to continue this topic. He knows that athletes still have to use it. Results speak for themselves, so Hua Tou returned to the side of technical changes and asked: "Has my starting position been set?"

"Well, a new version is out, but as you gain muscle again and increase muscle content, you may have to make changes." As soon as Randy mentioned the professional stuff, he quickly got into the mood and clicked. Clicked the mouse and said: "This is your torso measurement, take a look."

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

"I remember that the optimal range should be around 0 to minus [-] degrees. This shows that my current body cannot bear a better forward tilt angle of the trunk."

"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 rested for so long, and after changing feet, you cannot exert and output your entire strength. This way If your torso is tilted forward, it won’t be very good.”

"So now I feel like this angle is your current loading angle, and as your body recovers and trains again, this angle will readjust and change."

"What about the forward angle of the trunk at the moment of stepping off the starting block?" Su Shen looked at the model on the screen and continued to ask.

"What do you think of the plan I proposed, Mr. Ralph Mann?" After Su Shen finished speaking, Randy said with a smile: "That guy seemed to have figured out something at once, and he quickly dived into research. He was very interested in the book on sports mechanics that you and he wrote together."

"If you hadn't asked him to train with Liu, I would have doubted..."

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

In the last life of Ralph Mann, the classic short-span mechanics was released, which will also be the guiding bible for many athletes and sports organizations in the future. In this timeline, Su Shen will complete it with Ralph Mann, and he will also The former sports concept is filled with gaps, and some concepts from the next few decades are added to make it more advanced.

"However, you two are really brave enough to actually change the Golden Four Steps into the Golden Three Steps?"

When Randy said this, he smacked his lips a few times, as if he thought what this was

"Although I have heard of people doing this before, they are all based on experience and none of them are guided by a theoretical system."

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

"After all, Mr. Randy, you still prefer coaching, and Ralph is better at scientific research." Su Shen smiled and said: "And you also said, in fact, some people have discovered the shortcomings of the golden four steps a long time ago, and they have already been compared with the current sprint. The system is becoming more and more mismatched, and some keen coaches have begun their own reforms, which shows that in fact, it has reached an opportunity point for change, but someone still needs to give it a final kick."

"It's easy to say it, but it's the most difficult to summarize it into a scientific theory." Randy thought about the thing they were studying when he saw it, and he didn't stop thinking about it for a long time. He kept studying it. Think about something like this. How to use it on athletes.

If it were someone else, it might take a long time just to accept it, but if it were Su Shen, it would definitely solve this problem quickly.

Because this thing was originally proposed by themselves, wasn't it?

Maybe I still need them to teach me.

"If the changes are completed, it will be a big technological revolution for the entire industry." Randy said: "As more and more people are starting to do the eight-to-seven in short span, technology is always improving. It’s progressive.”

"Then look at the forward angle at the moment of your first step off, which is currently 60 degrees. According to your golden three-step rule, if you want to do this well, it is best to be within 48 degrees, and at least 53 degrees. It’s possible to complete the next few steps.”

"If possible, look at your three-dimensional model. Y should be above 85, and the rest should be above 80."

"Then there is the problem of the angle of your calf and thigh." Randy said: "Because you changed the starting foot, your angle is a little smaller now. Because after changing the starting foot, your body's burst of strength has changed. The moment you kick out has also changed. If excellence is measured at [-] degrees, you now only have [-] degrees. The angles of your front and rear feet are also very different from the three golden steps you have done. However, You have just started to change your feet, and I estimate that you will recover a lot later."

"I recommend that you change the angle of the knee joint of your back leg. It would be better to open it a little further back. It will give you more strength easily. Your current strength is not close enough to this number."

"Yeah, I know." Su Shen nodded after looking at it. He agreed with Randy. His current body rhythm and sense of force have changed. In addition, in order to completely forget the previous muscle memory some time ago, his muscles are now The power is not as good as before, so let’s adjust it now.

"Then let's talk about the most critical points if you want to change to the golden three-step. One of them is the angle between your calf and thigh when your back leg kicks off the starting block. In the previous four-step setting, The angle between the trunk and the thigh is about 90 to 110. When stepping off the starting block, the thigh does not extend much, and the process of increasing the angle between the upper body and the thigh is relatively long, so the vastus internalis is the first to move the calf. When the knee is extended in a relatively static state, the contraction range of the muscle will be limited." Randy looked at the newly made three-dimensional model and said: "Now your method requires the calf in the first step. The angle between the thigh and the thigh is between 155 and 145, and at the same time, it is necessary to prevent this angle from expanding further, so as not to affect subsequent force exertion."

"Otherwise, the amplitude of the vastus medialis muscle will be small, which will also have a great impact on the use of three-dimensional force in the starting stage of sprinting and subsequent steps. Look at this set of data." Randy pushed the computer in front of Su Shen and clicked on it. One page said: "This is your previous four-step start, and this is your speculated future three-step start model. There may be no difference in the average net generation amplitude between sprinters between the former and the latter, but in the starting stage, the latter The sagittal vector of "Thus, a more forward-inclined vector and a greater anteroposterior might influence the average front-to-back block acceleration between them for a sprinter who starts in the latter way than a sprinter who starts in the former way."

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

"And this fluctuation of more than ten degrees has always existed, so I am a little unsure."

"At the same time, there is another problem with the three-step start, that is, it is easy to over-extension and too much air time, which will undoubtedly greatly slow down the effect of changing from four to three."

Randy was also exposed to this new startup mode for the first time, no less than the original proposal of changing the short span from eight to seven.

Therefore, it was somewhat difficult for him, a famous track and field coach.

Although he was given time, he could slowly deliberate and solve the problem, but now it was obvious to Su Shen that he did not have the time to wait, so he directly said the answer:
Let’s not get hung up on these ten-degree fluctuations.

I think this problem can be avoided by actively pulling the ankle forward.

Not only can it reduce over-extension, but it can also reduce the air time caused by over-extension.

"Is this really possible?" Randy was stunned. He didn't expect that Su Shen would answer the question he had been struggling with for so long and put forward a clear solution.

"What about the excessive swing time of the swinging leg in the air after it was changed to a three-step start?"

After hearing this, Su Shen said without hesitation: "Just use my latest idea of ​​'half credit card' to 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 before.

"This is the tentative decision." Su Shen explained: "Because this will be thinner and thinner than Yuanbi's credit card technology, and will reduce the landing space. It can also be called paper landing technology."

"Because as long as the operation is good enough, it can be thinner than the credit card landing technology, which is more conducive to shortening the landing time." "That is to say..." Randy suddenly thought of something and said: "Originally, the foot was made before landing. The greatest pursuit of ankle dorsiflexion of the foot is to achieve ankle dorsiflexion at the moment the foot lands on the ground. The gap between the heel and the running track can only be stuffed with a credit card. Now it has become a piece of paper. Such a small change will not accumulate. If it becomes too much, it will eventually affect the 0.01-meter race based on [-] seconds."

"It's not just that." Su Shen said: "If successful, it can further increase the cadence limit. Just like credit card technology can further upgrade everyone's cadence and open up the original constraints, the same will be true if this technology is done well. Because this can further shorten the touchdown time, so in other words..."

"It's impossible not to improve your cadence."

"You're such a...monster."

"That's not all. Our laboratory also conducted tests to use 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 the joint coupling motion within the limb. Knee joint - Ankle (KA) coupling is less coordinated than hip-knee (HK) coupling during the stride phase (mean CRP: KA 89.9° HK 34.2°) and produces lower within-athlete CRP variability in stance sex (VCRP). Ground strike (TD) produces more anti-phase motion and greater VCRP than toe strikes...that is, instability in lower limb coordination patterns is thought to be necessary while doing just fine Minimize this instability and further increase coordination patterns in the lower limbs."

"In this case……"

Before Su Shen finished speaking, Randy continued: "In this case, your original lower limb pattern can further increase the advantages and reduce the disadvantages in the instability of the necessary adjustment pattern, that is to say..."

"The upper limit of lower limb mode movement will also be further increased to break through the bottleneck, right."

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

"And my original rhythm system and movement system can no longer adapt to these latest technical concepts, so in order to improve myself and adapt to these conceptual technologies, I have to change my feet and rebuild."

Randy:…

After 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 was actually able to solve several problems with obvious benefits at the same time.

Is this still a human being? ? ?
Maybe when Randy saw Su Shen abandoning his martial arts, he felt a little worried, but now...

He felt that if there was a person in this world who could successfully "re-cultivate his martial arts" like this.

That must be Su Shen.

It must be this young man whose brain was enlightened by Jesus.

Every time he thinks about this, Randy seems to feel like...

Every time I got stuck, it seemed like the young man in front of me would help me out.

Just once or twice.

You could call it a flash of inspiration, but it happens every time.

Randy almost thought that this guy was "all-knowing and omnipotent" and was already ready to "answer his questions".

This "arrangement".

It made him feel that his brain was not enough.

"Do you have any more questions, Mr. Randy?" Su Shen looked at Randy who was still in a daze and asked.

"Forehead."

Randy froze.

"Nothing."

At the same time, he complained in his heart:
Even if there is.

I guess you have already thought of a way to solve it.

You're the same as Ralph anyway.

They are all scientific athletes.

We don’t understand this either.

We don't ask anymore.

"Then let's start the training session of the three golden steps."

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

Randy, who had recovered a bit and was about to look at the training plan, was almost staggered by these words.

"One, a month? This is a new technology, a brand-new thing. In addition, you have to reconstruct your sports performance pyramid, and you need to constantly modify the technical details as your body recovers. You... you can do it in half a month. Is it done?"

"Is this time..."

"Yeah." After hearing this, Su Shen nodded and said, "I also think it's a bit too long, so let's try for it..."

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

"There's still a lot of stuff to do later."

"It's true that we don't have enough time."

"After all, this is just a start, not a core change, right? There is no time to allocate more to him."

"Half a month is enough."

Randy:? ? ?
Randy:! ! !
Randy:…

PS: The three golden steps are a theoretical concept proposed by Ralph Mann in his 2011 book on short-span mechanics. Compared with our previous analysis of the first four steps, it does mean a bit of "replacing four with three."

Technical changes are a bit difficult to write, but I will try my best.

O(╥﹏╥)o~~~~~~~~~~~~~~
It’s a new month. Remember to use your little hands and vote.
