The Su God of the Reopening of the Sports Arena

Chapter 519 Eating technology is like eating hamburgers

Ersha Island.

Because Su Shen wants to directly integrate the upper body into the existing ground-grabbing system this time, it will take him more time.

Otherwise, formal adaptive high-speed training can already begin now.

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

Because they don't understand now, how to integrate these perfectly, remember to perfectly integrate, not to copy mechanically, the kind of kneading that can only have counterproductive effects.Although they read these things written by Su Shen, they immediately understood the feasibility of this, but how to do it is the best, how to do it is the most reasonable, and where the scientific data is, this is not easy.

There are no ready-made examples.

Su Shen began to communicate with them in depth, which is part of the real scientific research type, which requires the application of a large number of biomechanics and physics formulas.

……

"The ground support can be divided into three stages: forward kick, vertical, and back kick. We all know that in the forward kick process, the support point of the foot is in front of the projection point of the center of mass of the body, and the force of the ground on the person acts as a deceleration. How can we get The largest "braking point" and the largest "push point"? Then we do a calculation, if the front support is cushioned, and the toes fall 3cm in front of the projection point of the center of mass of the body, the largest "braking" phenomenon will occur."

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

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

Without real scientific theories and calculation formulas, I'm afraid they won't be able to convince them.

"Because of the back kicking process, the support point of the feet is behind the projection point of the body's center of mass." Su Shen said: "At this time, the force of the ground facing the person has an acceleration effect. And because the force of the ground facing the person is the human body running forward active force, so we can calculate it like this——————————————————————————————————————————————Center of mass speed is the running speed of people during running, which is the speed of people relative to the ground. Ground, the direction is approximately forward. The athlete presses the thigh and stretches the calf during running and drives the calf and foot to pick up the ground. The speed of the foot relative to the center of mass of the human body is regarded as the relative speed. V1 represents the center of the foot, and the direction is backward and downward... ..."

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

"Because the forward velocity V1 of the center of mass is generally greater than the speed V2 of the feet facing the ground backward and downward, so the direction of V3 feet facing the ground is generally forward and downward."

"Since the direction of V3 is generally forward and downward, the angle between the speed direction of V2's center-to-center and V1's center-to-ground should be much larger than 90 degrees. Therefore, the size of V3's feet to the ground is generally much smaller than the speed and direction of V1's center-to-ground. Therefore, the ground-grabbing action makes the speed of the foot to the ground smaller than that without the ground-grabbing action. Since the ground-grabbing action makes the speed of the foot-to-the-ground smaller than that without the ground-grabbing action, when the forward pedal buffers, due to the ground-grabbing action, the The interaction between the foot and the ground has a small forward pedaling resistance, which is equivalent to adding an additional driving force. This is what we are doing now, but if..."

"How about adding an upper limb link to the lower limb link?"

"From the perspective of human dynamics, when the front of the foot is on the ground, the forces on the human body include gravity G, the elastic force N of the ground to the foot, the friction force f of the ground to the foot, and the resistance of the air to the body F, O is the action point of the ground to the feet, C is the center of gravity, b is the action point of the resistance of the air to the body, and the human body is only affected by the friction force f of the ground to the feet and the resistance F of the air to the body in the horizontal direction. The resistance F of the body is small. At this time, if an upper body chain link is added to the lower body chain link, that is, additional shoulders, elbows, and arms, can the speed of the foot to the ground be lowered, that is, when V3 is small, the forward pedal The resistance, that is, the frictional force f of the ground against the foot at this time, will be smaller?"

"Keep talking, Su." Ralph Mann has gradually understood that he is indeed an expert in mechanics in this field.

"Then it will be more 'sufficient' to pick up the ground at this time."

"According to the momentum theorem, the speed loss of the human body in the horizontal direction is reduced by deceleration."

"The impetus for landing will increase accordingly at that moment."

"Then in the same way, with V3, the front pedal resistance is also smaller. Is it to further reduce or even eliminate the phenomenon of "braking" during the landing process?"

"The following is the link map of my new ground chain. The top and bottom are connected. The formula and calculation process are as follows..."

Su Shen wrote quickly, and the dense calculations began to appear in front of the eyes of the two people. The most frightening thing was that Ralph Mann actually...

No problems were found.

God, this guy isn't installing Jesus' head on track.

Otherwise, how is this possible?

This is horrible.

A person.

He actually completed the optimization of technical projects that required a large number of teams and a lot of time for demonstration and verification by himself.

all of these.

Ralph Mann watched, 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 God Su told him the facts, what he thought was impossible before, now...

Everything is possible.

"Genius-like idea. Genius-like design. Genius-like argument." Ralph Mann said three "genius-like" in a row, which is enough to reflect the state of mind of this American biomechanics expert professor at this moment and mentality.

The essential……

He is not here.

too frightening.

"Professor Ralph? Professor Ralph? Are you listening to me?" God Su yelled a few times, and seeing that Ralph Mann didn't respond, he had no choice but to push the latter with his hand.

"I said old man, why are you distracted? Are you getting old and losing energy?" Randy teased.

"What do you know?" Ralph Man said angrily, "You are not in the field of biomechanics, you have no idea what Su means. If this thing is released, it is likely to promote technological innovation in the entire track and field world." and new technological developments.”

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

After all, such a person has exceeded his expectations by a lot.

If the tolerance value is exceeded, it is naturally impossible to maintain calmness.

"But these theories have just been put forward, how long will it take you to put them into practice?" Randy raised his 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 winter training?

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

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

"By the way, Coach Randy, my diamond squat seems to have a certain movement pattern that needs to be corrected. Then you can help me analyze it with the equipment."

"Also, my future 30-40 meters optimization plan, specifically for improvement, also follow what was agreed last time."

"I still have time left to do this."

Randy: ...

Ralph Mann: ...

God, does this guy eat technology as easily as he eats hamburgers?

Hearing what Su Shen said later, the two of them were already completely messed up.
