Ersha Island.

Because Su Shen had to directly integrate his upper body into the existing ground-shaving system this time, he would have to spend more time.

Otherwise, you can start formal adaptive high-speed training now.

But this is also a new topic for Randy and Ralph Mann.

Because they don’t understand how to perfectly integrate these things, remember that they are perfectly integrated, rather than copying them, and that kind of combination that can only have the opposite effect. Although they read these things written by Su Shen, they instantly understood the feasibility, but how to do the best, how to do the most reasonable, and where the scientific data is, it is not easy.

There are no ready-made examples.

Su Shen began to have in-depth communication with them, which is part of the real scientific research type, and requires the use of a large number of biomechanical and physical formulas.

...

"The grounding support can be divided into three stages: forward pedal, vertical and rear pedal. We all know that the forward pedal process is the support point of the foot in front of the projection point of the center of mass of the body, and the ground plays a deceleration effect on the force of the human. How can we obtain the largest "braking point" and the largest "push point"? Then let's do a calculation. If the ground is buffered during the front support and the toes fall 7cm in front of the projection point of the center of mass of the body, the maximum "braking" phenomenon will occur."

"The toes fall 7cm in front of the projection point of the center of mass?" This is Ralph Mann's main area, and he immediately asked: "Why is 7cm? Do you have any basis? Sue?"

These people are real industry experts and professors, and they can't just pull a few tiger skins to make big banners.

Without real scientific theories and calculation formulas, I am afraid they cannot be convinced.

"Because of the rear pedal process, the support point of the foot is behind the projection point of the center of mass of the body." Su Shen said: "At this time, the ground faces the force of the human being to accelerate. And because the force of the ground faces the human being is the main driving force for the human body to run forward, we can calculate this way-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"So, according to the principles of mechanics, this should be done." Su Shen quickly wrote on paper: "Absolute speed V3 feet to ground = V1 V2."

"And because the general speed of the centroid forward V1 center to the ground is greater than the speed of the foot to the back and lower ground V2 center to the center, so the direction of the foot to the ground V3 is generally facing the front and lower direction."

"Since the direction of V3 is generally facing the front and lower directions, the angle between the V2 foot and the center of V1 and the ground should be much greater than 90 degrees. Therefore, the size of the V3 foot to the ground is generally much smaller than the speed and direction of the center of V1 and the ground. Therefore, the ground-stripping action makes the speed of the foot to the ground smaller than when there is no ground-stripping action. Since the ground-stripping action makes the speed of the foot to the ground smaller than when there is no ground-stripping action, in this way, when the front-stripping action is buffered, the front-stripping resistance of the interaction between the foot and the ground is small, which is equivalent to adding an additional driving force. This is our current ground-stripping action, but if..."

"Where is another upper limb chain link to the lower limb chain link?"

"Analysis from the human body dynamics, when the front of the foot supports the ground, the force that the human body is subjected to is gravity G, the elastic force of the ground facing the foot N, the friction force f of the ground facing the foot and the resistance F of the air to the body F, O is the action point of the ground facing the foot, C is the center of gravity, b is the action point of the resistance of the air to the body. The human body only receives friction force f of the ground facing the foot and resistance F of the air to the body in the horizontal direction. Generally, the resistance F of the air to the body is smaller. At this time, if an upper limb chain link is added to the lower limb chain link, that is, the additional shoulders, elbows, and arms, can the speed of the foot to the ground be made, that is, V3 is smaller, and the resistance of the front pedal, that is, the friction force f of the ground facing the foot will be smaller?"

"Continue talking, Sue." Ralph Mann had gradually understood that he is worthy of being an expert in mechanics in this field.

"Then the ground will be more 'full' at this time."

"According to the momentum theorem, the speed loss of the human body in the horizontal direction is that it reduces the speed."

"The driving force for landing will increase accordingly at that moment."

"So the same way, the V3's front pedal resistance will be smaller. Is it to further reduce or even eliminate the "braking" phenomenon during the landing process?"

"Below is the link diagram of my new floor-sharing. The upper and lower parts are connected. The formula and calculation process are as follows..."

Su Shen quickly wrote, and the dense calculations began to appear before the two people. The most terrifying thing was that Ralph Mann actually made a proof of it...

No problem was found.

God, this guy is not installing Jesus' head in track and field.

Otherwise, how could this be possible?

This is so scary.

one person.

He actually completed the optimization of technical projects that required a large number of teams and a lot of time to prove and verify them alone.

All of this.

Ralph Mann looked at it and it took less than an hour in total.

this……

Ralph Mann is a scientific research athlete. He has never really admired anyone in this aspect in his life, but this time, he has to admire him. Because Su Shen told him with facts that what he thought was impossible before, now...

All are possible.

"Genius-like ideas, genius-like designs, genius-like arguments." Ralph Mann said three consecutive "genius-like", which is enough to reflect the mood and mentality of this American expert professor of biomechanics at this moment.

key……

He is less than eighteen years old.

Too scary.

"Professor Ralph? Professor Ralph? Are you listening to me?" Su Shen shouted a few times. Seeing that Ralph Mann had no response, he had to push the latter with his hands.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! "I said, "Old guy, why are you distracted? Are you old and lacking in energy?" Randy teased.

"What do you know?" Ralph Mann said angrily: "You are not a person in the field of biomechanics. You don't know what Su means. If this thing is sent out, it is likely to promote technological innovation and technological development in the entire track and field industry."

"Give me a few weeks, no, give me a few days, I will definitely complete the preliminary verification. If you want to publish this paper, I will definitely sign it for you. No, I can write an introduction for you." Ralph Mann rarely loses his composure, but this time, he really loses his composure.

After all, such a person has exceeded his expectations.

If the bearing value exceeds, you will naturally be unable to remain calm.

"But these theories have just been proposed, how long will it take for you to put them into practice?" Randy raised her own concerns.

After all, theory is theory and practice is practice. Is there any experience to follow? Is there enough time for the remaining half of the winter training?

Su Shen nodded with a calm face and said, "Don't worry, no problem, the rest of the practice is enough."

"I will understand the entire technical movement before the end of the winter training."

"By the way, Coach Randy, my diamond squat seems to have some exercise mode that needs to be corrected. Then you can help me analyze it with the equipment."

"Also, my future 30-40-meter optimization plan is designed to improve in detail, and we should follow the last time we agreed."

"I have time left to do this."

Randy:...

Ralph Mann:...

God, is this guy as easy to eat skills as burgers?

After hearing Su Shen talk about it, the two of them were completely messy.
