How important is the butt in running?

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 "legs".

What does it mean to run with your legs?

China's sprinting theory overemphasizes one point of view, that is, "the thigh is raised, and the back pedal should be sufficient".

This is "running with your legs".

There is even a strange theory of "high center of gravity", which believes that the current domestic hip muscles are too developed, which will affect the "high center of gravity" of athletes. Therefore, at present, many athletes in my country do not dare to exercise their hip muscles and strength too much.

This issue was even mentioned in 2013's Athletics.

And in fact, does anyone in our country see this drawback and mistake?

Of course, in 1984, Li Chengzhi of China found many problems when he studied the comparison between the sprinters in the United States and the sprinters in China. For example, in the support stage of the American athletes, there is an obvious flexion action in supporting the knee joint.

The knee angle is significantly smaller than that of Chinese athletes.

The change in knee angle during the push extension is significantly greater than that of Chinese sprinters.

And he also calculated a preliminary data, the average knee angle of sprinters in the United States is 149.4 degrees, and the average knee angle of sprinters in China is 152.1 degrees. At the beginning of the push, the athlete of the United States is 134.2 degrees, and the knee angle changes to 10.2 degrees. The corresponding data in China is roughly 149.1 degrees, and the knee angle changes by 3 degrees.

The average kicking angle of Chinese athletes is 56.6 degrees, and the angle of Chinese athletes is 67.7 degrees.

At that time he thought that the most critical problem caused this difference was in the hip muscles.

Because the strong hip muscles can make the transfer of power more powerful.

It's a pity that such a thing that was put forward in 84 years did not make much waves in China, and it was only discovered after the comprehensive promotion of new technologies later. It turns out that what people have discovered, we have discovered early, is not the so-called, it is really decades behind others and no one has observed.

If you calculate anatomy and biological kinematics, there is much more to be said.

This all tells us a problem.

Whether it is ability, observation, intelligence, or innovative ideas, we are never inferior to others.

The difference is that they do not really pay attention to these people, and the "stubbornly old-fashioned" forces are still in the most mainstream position, resulting in these real "reformists" becoming "heretics" and "minorities", and the final result can only be sunk in the sea, only a page of "waste paper" on books or materials.

Even a layman is sure to find something interesting.

That is, in China's sprinting sport, during this time period, the buttocks are mainly "flat", while foreign European and American sprinters, one says one, almost all of them are "buttocks" and "big butts".

Why is this so, look at a topic that is deeply researched -

Researchers from the School of Health and Exercise Sciences used a magnetic resonance imaging (MRI) scanner at the National Centre for Sports and Exercise Medicine at the Loughborough campus to measure the magnitude of 23 lower body muscles in 42 men. Among them were 5 sprinters, 26 "sub-elite" athletes, and 11 untrained personnel. Sprinters averaged a personal best of 9.99 seconds.

The study, in collaboration with British athletics, was particularly unique in that it used "sprinters who were bigger and faster than ever before, and the anatomy of the muscles was measured more rigorously".

The research team found.

Although top sprinters are usually muscular, they have a very specific pattern to their muscles – some muscles in the elite group are much larger than those of untrained men, and they are also larger than those of sub-sprinters.

For example, the hip extensor muscles, the so-called muscle groups that extend the hip joint, have a difference of 32%. However, other muscle groups, such as the plantar flexors, which are calf muscles, are similar in size in elite and sub-elite sprinters. If you look at individual muscles, the gluteus maximus and its size are considered the key to achieving rapid movement.

Why, the following data is the key to the key.

Among all sprinters (elite and sub-elite), the performance varies.

The range is from 9.91 to 11.25 seconds.

The researchers found that 44% of this performance difference was caused by the size of the gluteus maximus, with elite sprinters having 45% larger muscles than sub-elite sprinters.

That's a statistic alone, it's scary enough.

If you really look into it, you should know what this ratio means.

I also know why my country's sprinting, in this time period, the "king of national uniforms" actually faced an Olympic B standard and reached a difficult level. Because, it's wrong in essence, and the biggest driver is also wrong, so how can you play it?

Isn't it funny?

You use "leg drive", but people take "butt drive" according to anatomy and biodynamics.

To use an inappropriate analogy, it's the difference between a bike and a Harley-Davidson.

The engines are all different.

Or maybe we haven't really used the "engine" at all.

Professor Flanders of the Faculty of Health and Exercise Sciences also said: "This conclusion is surprising. Because it is believed that sprinting is influenced by many factors, including technique, psychology, nutrition, and the anatomy of other structures. But in fact, the most critical areas are often overlooked, and for fast running, the size of the 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 seems so simple but important, we can explain a lot of things. ”

Look, that's pretty straightforward, isn't it?

But this instrument is a very new thing, and this paper was only published around 2020, so there is really a lack of real scientific data at the beginning. But once there is, everything is revealed.

The importance of "butt" has been increased countless times at once.

And the funny thing is that my country has insisted on the "leg drive" for so many years, and under the coldness of science, it has completely become a two-legged pedal.

If you ride a bicycle with two feet, how can you beat the speed at which someone crashes into an engine?

Here, there is no need to talk about other data research, just this piece of paper around 2020 is enough to break the pseudo-scientific running method in China for a long time.

Now everyone knows why yellow people can't run for 10 seconds, except for opening ten seconds, which is something that only top athletes can do, only more than 100 people have entered in the history of 2021, even black people need top talent to achieve, it is by no means "known" that you can break ten by lifting your legs.

Any race that wants to break 10 is an absolute talent and a top athlete.

And the current group of people in my country, with the "bicycle" running method, have run so fast, especially Su Shen himself, with the "bicycle running method" forcibly opened for 10 seconds, you know how terrifying this is, what kind of talent is this.

If you had been trained in science earlier, this would never have been the case.

It will never be 32 years old to open 9.90.

Therefore, Su Shen, who is deeply aware of this theory, after the reopening of this life, pays more attention to the importance of this "big ass" than anyone else.

Nothing else needs to be said - the big butt is the engine of a sprinter.

The stronger your butt, the more powerful your engine will be.

This one, published in Medicine and Sport and Exercise Science, has thoroughly shown this -

Extrapolating from the results of the study, theoretically, the longer the gluteus maximus, the more power the runner will be able to generate, which will increase the sprint speed. That said, for those who are training for track and field running, focusing on increasing the size of the gluteus maximus and other gluteal extensors will improve sprint performance.

Therefore –

Now do you know how important "big butts" are for sprinting?

That means you're a bike, a motorcycle, a sports car, a supercar, or even a race car.

After Su Shen reopened in this life, there was a goal that must be accomplished, and that was ......

You have to get bigger, rounder, and more upright big butts.

Man.

They all crave a more powerful "engine".
