Ersha Island.

Although it has entered the winter, the venue on Ersha Island is not idle at all.

It's hot every time.

Even Liu Xiang sighed that training here, I'm afraid that no one dares not to work hard.

Otherwise, it is really out of step with the general environment.

Of course, if you try too hard, you will be stopped.

This is the characteristic of Ersha Island.

"There is a problem with the boot mode, and we are still debugging the latest sensors."

"Of the seven starts, the best was the second, where the sensor showed the closest to overcoming gravity at 3%, air resistance at 18%, acceleration at 57% and braking at 22%. However, the energy supply for the phosphogen system is the seventh type, which is currently the most suitable. ”

"It could be a matter of control, it could be a habit of the body, or it could be a balance that seems unbalanced."

Su Shen came over and looked at the sensor data, and nodded while drinking water, I have to say that the sports sensor Su Shen system has now started to use it first, which has huge benefits for the improvement of the details of athletes. After all, after being promoted to the present, Su Shen himself may not understand what should be done to be the most appropriate.

The changes in the body are getting bigger and bigger, and the optimal position can no longer be calculated from the original body.

The original experience is even somewhat inaccurate.

It's time to reposition and redesign.

"What about the first four steps?" Su Shen asked: "The first four steps are the key to starting, and they are also a standard value for whether you can accelerate smoothly. ”

It is important to know that the first step of the start and the steps of the subsequent steps have a great impact on the quality of the acceleration run. Too little stride length does not guarantee a rapid increase in speed, and too large a step spoke will lead to "bigger strides" and lower speed. The angle of leaning forward decreases with the increase of speed, and you can finally get closer to the posture of running in the middle of the road.

So in addition to starting, we have to look at the first four steps, Su Shen is going to re-optimize the entire movement posture.

The amount of detail is huge, there is no team, no advanced guidance, and even these high-tech studies of the Su Shen Department, one less is definitely impossible to do in the winter training. At this level, it is difficult to maintain, let alone progress, after 9.80s, this is really 0.01s It takes a lot of effort, and even Su Shen himself feels that 9.80s is really about to start challenging the limits of the human body and even physiology.

"Mr. Su, this is the analysis chart of these seven accelerations, including the changes in the time characteristics of the acceleration running and pedaling (T1T2T3 are the front support time, the rear support time and the support time, respectively. Su Dawei showed Su Shen the curve chart displayed by the software on the computer screen, Su Shen looked down, and asked for a while: "What about the change in the impulse of the acceleration running and pedaling?" ”

"Mr. Su here." Su Dawei clicked the mouse, and a new comparison chart popped up on the screen: "This is designed according to the three-dimensional kicking force of the speed running you said Mr. Su———— the change trend of the time curve and the three-dimensional kicking force diagram of running on the way (T1 is the front support time, T2 is the support time, and the abscissa is 0.01 seconds per grid. ”

"This is a function of time as a function of the horizontal position, velocity, and acceleration of the centroid of these seven times." Su Dawei stared at the screen with his eyes and said seriously: "Here to fire the gun; T1 first reaction; T2 hands off the ground; T3 hindfoot off the ground; T4 is the forefoot off the ground. ”

"Okay." Su Shen looked at the pictures that Su Dawei called up on the computer and said, "What about the foothold posture?" ”

"It's a figure-eight, it's a line, it's a straight impact type."

"Mr. Su, in your figure-of-eight acceleration method, the left and right swing of the foot is the cause of the left and right swing of the body, if you can better strengthen the strength of the left body, especially the power control of the left leg, it may be better to add some centrifugal control training. There will be less energy to start dispersing. ”

"Hmm." Su Shen continued to ask, "What about the total center of gravity of the body?" What is the difference between a startup gap? ”

"Plot of the velocity of the center of gravity versus the horizontal forward velocity of the center of gravity over time." Su Chengzhi walked over and took another instrument and said: "The change trend of the horizontal forward component of the speed of the center of gravity and the speed of the center of gravity is very similar to these seven times, and the two are almost equal at the beginning stage, even in the later stage, the difference between the two is not too big, which means that Mr. Su, your center of gravity speed is controlled quite well." But judging from the chart, the horizontal forward velocity of the center of gravity has not yet reached the optimal solution of the champion model here, so you can see if you can adjust it again. ”

"The champion model has been updated again?" Su Shen asked, what the hell is this thing Ralph. Man has also put all his efforts into it, and the large investment in the Su Shen Laboratory in China has actually far exceeded the original version of the era.

Why?

None of them.

When you have money, it will be easier for you to cash out if you are naturally talented.

Money ability, you can't help but say, even in the field of sports, it's pretty easy to use.

"Yes, we're investing a lot now, and the whole system is based on Ralph. Mr. Manlao's championship model is based. While speaking, Su Chengzhi continued to analyze with Su Shen: "This is the displacement curve of Mr. Su's center of gravity in the vertical direction over time, from the start to the fourth step of the support leg kicking off the ground, with the body vacating and supporting, the displacement of the center of gravity in the vertical direction appears 4 peaks and 4 troughs, and with the gradual lifting of the upper body, the curve is on an upward trend, we think that your second peak and the third trough can be improved, if the second step converges a little bit, Instead, it may promote the overall performance of the third step, and then optimize the overall golden four steps. ”

"Okay, I'll pay attention."

"There is another problem, Mr. Su, in order to get a more adequate back pedal force in the first few steps of your fast running, on the one hand, you have to get a smaller back pedal angle through a lower center of gravity, out of a compromise, in the second and third steps here the upper body forward angle may be too large, which will cause the swinging leg to enter the support stage before the calf is fully opened, this is the display of the sensor, you can see, can you also adjust it slightly when the time comes."

Su Shen looked at the red area at the top of the screen and nodded.

This is the scientific team he wants, because even if he knows these things, it is difficult for him to do them all by himself, and he needs a team to pick out the details, relying on the scientific system and the champion system to pick out the details. Otherwise, on your own, you may be able to do it in front, and after breaking ten, it will be more difficult to advance each grade. For example, now in the 9.80s hard power level, if you want to move forward, there are too many things that need to be involved, and it is not easy to change a certain technology and add a certain technical action.

Otherwise, the level of five tiger generals within 9.80s would not be so few.

"And here, when Mr. Su swings his leg to the ground, the knee joint angle is already small, and if he runs on the way, he feels that he can't achieve the purpose of cushioning by reducing the knee angle, which will cause additional wear and tear near the knee for a long time. On the other hand, the support leg should make a larger percussive active pushback, so as to see if you can get more pushback force needed to accelerate the body, we have designed a set here based on the champion model, you can try it in subsequent training, to see if this backpress action can make the knee joint angle larger when kicking off the ground than when running. ”

"Okay." Su Shen nodded and said, "Is there anything else?" ”

"And this, and the latest thing, is the curve of the knee angle over time from the full folding of the upper and lower legs after kicking off the ground to the curve of the knee angle over time at the stage of kicking off the ground. Mr. Man said that if this is done well, it may also increase the efficiency of linkage force. ”

"Okay."

……

After analyzing a series of basic improvement systems, how to apply them to reality is the biggest problem.

Su Shen actually appreciates this, there are more problems, and there are more angles for improvement, so that athletes have direction and motivation.

For any top athlete, he is never afraid of hardship and tiredness, but he is afraid of losing direction and motivation.

Even if many things are not necessarily correct when analyzed by the champion model, even if they are correct, they may not necessarily be in line with the human body of Su Shen's current body, these are the places where theory and practice need to be combined.

It is also where the future winter training needs to be revised and really adjusted.

"There's a long way to go." Su Shen also laughed at himself slightly before leaving the training ground.

And after he left, Wen Yongyi and the others also finished training from the other side, and when they saw the equipment on Su Shen's side and the problems and improvement suggestions written on it, this time Wen Yongyi had not spoken, Yin Hualong immediately covered his eyes, as if there was some dazzling bright light on the whiteboard.

"What are you doing?" Wen Yongyi wondered.

"Don't let me see this dense stuff." Yin Hualong covered his eyes and walked briskly: "I'm afraid I'll feel like a waste after seeing too much." ”

Wen Yongyi: ......

He couldn't help but glance at it, and immediately, he didn't dare to look any more.

At the same time, I have a heart for Yin Hualong's approach.

Agreed.

PS: The first update ~~~~~~~~~~~ strengthen the winter training, let's see how Su Shen can go further!!

None of them.
