In the time period of later generations, it has been proved that the butt is one of the core driving forces of sprinting.
And now our country is still running with its "legs".
What does running with legs mean?
my country's sprint theory overemphasizes one point of view, that is, "the thighs should be raised and the rear pedal should be fully raised."
This is "running with your legs".
There is even a rather bizarre "high center of gravity" theory, which believes that the domestic buttock muscles are too developed at present, which will affect the athletes' "high center of gravity". Therefore, many athletes in my country do not dare to exercise their buttock muscles and strength too much.
This issue was even mentioned in the 2013 Track and Field.
In fact, have some people in our country seen this drawback and error?
Of course, in 1984, Li Chengzhi from my country discovered many problems when studying the comparison between American sprinters and Chinese sprinters. For example, American athletes have obvious flexion movements in the support stage of supporting the knee joint.
The knee angle is significantly smaller than that of Chinese athletes.
The changes in knee angle during the pedaling process are obviously larger than those of Chinese sprinters.
He also calculated a preliminary data. The average knee angle of the American sprinters is 149.4 degrees, while the average knee angle of the Chinese sprinters is 152.1 degrees. When the pedal is started, the average knee angle of the American athlete is 134.2 degrees, and the knee angle changes to 10.2 degrees. The corresponding data in my country is roughly 149.1 degrees, and the knee angle changes to 3 degrees.
The average angle of the American athletes' pushing the ground is 56.6 degrees, while the average angle of the Chinese athletes' pushing the ground is 67.7 degrees.
At that time, he believed that the most critical issue in the difference was the buttocks muscles.
Because powerful buttock muscles can transfer strength and become stronger.
Unfortunately, this thing that was proposed in 1984 did not cause much trouble in China, and it was discovered only after the comprehensive promotion of new technologies. It turned out that we discovered things that people discovered were also early on, not so-called. It was really lagging behind others for decades, no one observed them.
If we calculate it again, there is more to say about anatomy and biological kinematics.
This tells us a question.
No matter our ability, observation, IQ, or innovation ideas, we are never worse than others.
The worst thing is that the "stubborn and conservative" forces are still in the mainstream position, which has led to these real "innovatives" becoming "heretics" and "few". The final result can only be a "stone" and a "small" and a "small" in the end, and only become a page of "waste paper" in books or materials.
Even if you are an outsider, you will definitely find something interesting.
That is, during this period of time, the butts are mainly "flat", while those in foreign European and American sprinters say that almost all have "squinted butts" and "big butts".
Why is this happening? See a topic of in-depth research-
Researchers from the School of Health and Sports Sciences used the latest researched next-generation magnetic resonance imaging (MRI) scanner at the National Center for Sports and Sports Medicine at the Loughborough campus to measure the size of 23 lower body muscles in 42 men. Five sprinters, 26 "sub-elite" athletes, and 11 untrained personnel. The sprinters averaged 9.99 seconds in their personal best.
This study, in collaboration with British track and field, is particularly unique because it uses “larger, faster sprinters than ever before and takes more stringent measurements of muscle anatomy”.
The research team found.
Although top sprinters are usually muscular, their muscles have very special rules - some muscles in the elite group are much larger than those of untrained men and are also larger than those of Asian sprinters.
For example, the hip extensor muscles, which are called muscle groups that extend the hip joint, have a different size of 32%. However, other muscle groups, such as the sole flexor muscles, are similar in size among elite and sub-elite sprinters. If a single muscle is viewed, the gluteus maximus and its size are considered key to achieving rapid movement.
Why do you say that, the following data is the key among the keys.
Among all sprinters (elite and sub-elite), performance varies.
Range from 9.91 to 11.25 seconds.
The researchers found that 44% of this difference in performance was caused by the size of the gluteus maximus, and elite sprinters had 45% larger muscles than elite sprinters.
This data alone is scary enough.
If you really look inside, you should know what this ratio means.
We also know why our country's sprinters will face a Olympic B-mark during this period of time, and it will be difficult to reach the Olympic B-mark. Because, it is essentially wrong, and the biggest driver is also wrong. How can we play it?
Isn't it very funny?
You use "leg drive", but they use "butt drive" based on anatomy and biodynamics.
To use an inappropriate analogy, it is simply the difference between a bicycle and a Harley Motorcycle.
The engines are different.
Or it can be said at all - we haven't really used the "engine".
Professor Flander of the School of Health and Exercise Sciences also said: "This conclusion is surprising. Because people think that sprinting is affected by many factors, including technology, psychology, nutrition, and the anatomy of other structures. But in fact, the most critical parts are often overlooked. For fast running, the size of muscles is more important than we think, especially the size of the hip extensors and gluteus maximus. Now that we find a single muscle that looks so simple but important, it can explain many phenomena."
Look, they are saying it straightforwardly, right?
But this instrument is something that was only available later, and this paper was published around 2020, so there was indeed a lack of real scientific data at the beginning. But once it was available, the truth of everything was revealed.
The importance of "butt" was suddenly increased countless times.
What’s funny is that our country has insisted on “leg drive” for so many years, and under the coldness of science, it has completely turned into a tripod with two legs.
How can you compare to the speed of a bicycle with your feet when you install an engine?
Here, there is no need to mention other data research. Just this paper around 2020 is enough to break down the pseudoscientific method in China for a long time.
Now everyone knows why yellow people can't run into 10 seconds. Apart from ten seconds of opening, they are what top athletes do. In the history of 2021, only more than one hundred people have entered. Even black people need top talents to achieve it. It is definitely not what "public intellectuals" say, they can break ten by just lifting their legs.
Anyone who wants to break ten is absolutely talented and top athlete.
Nowadays, the group of people in my country have run so fast with the "bicycle" running method, especially Su Shen himself, who forced himself to open it for 10 seconds with the "bicycle running method". You will know how terrifying this is and what kind of talent it is.
If you received scientific training earlier, this would never be the case.
It will never be able to open 9.90 at the age of 32.
So Su Shen, who knows this theory deeply, pays more attention to the importance of this "big butt" than anyone else after reopening this life.
There is nothing else to say - the big butt is the engine of the sprinter.
The stronger your butt, the stronger your engine will be.
This is published in "Medical and Sports and Sports Science", which has completely demonstrated this -
From the research results, theoretically, the longer the gluteus maximus, the more powerful the runners will be able to generate, thereby increasing the sprint speed. That is, for those who want to train track and field races, focusing on increasing the size of the gluteus maximus and other hip extensors will improve sprint performance.
therefore--
Now do you know the importance of "big ass" for sprinting?
This means, are you a bicycle, a motorcycle, a sports car, a supercar, or even a racing car?
After Su Shen reopened this life, there was a goal that must be completed, that is...
You must develop a larger, rounder, and more perky big butt.
It's a man.
Everyone yearns for a stronger "engine".
PS: Now everyone knows why Su Shen runs the fastest, because in China, his butt is the most upright ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
