Modification of hip delivery technique.
There are currently five hip transplantation techniques in China -
1. The theory of triaxial movement of the pelvis.
2. Swing your legs and bring your hips together.
3. Pushing on the ground to send the hips forward.
4. Central axis motion theory.
5. The pelvis is forward.
Make some key links that everyone is most familiar with from these five, and then try to extend them into the field of scientific hip delivery.
After everyone memorized the bone and muscle distribution map, Su Shen now speaks very smoothly. It will no longer be the same as when he first talked about it, and he would have to stop and explain where this part is for a long time every time.
"From the perspective of human anatomy - use human anatomy to analyze the body movement during running or walking. When the back pedaling support action occurs during body movement, the human pelvis will correspondingly twist to support the movement system. .In the human body system, the body's movement muscles and related skeletons cooperate and cooperate systematically to complete the twisting movements of the body skeleton and pelvis. The body twisting is based on the structure of the trunk, that is, the spine is composed of a series of related vertebrae. , vertebrae are connected by joints. These joints and intervertebral discs allow adjacent vertebrae to extend and flex upward and downward, and at the same time, they can extend and flex to both sides of the body in a small range. The spine is located in the center of the trunk and can To support the extension of the body, the thorax and trunk are the human skeleton structure. The back muscles of the body will then affect the movement of the spine, and the thorax will follow the rotation of the spine. The abdominal muscles will also provide support during this pulling process. The pelvis is like the disk of a machine. The wheel also twists with the movement of the spine. The twisting between the body's trunk and the overall structure of the pelvis is in an opposite state, one to the left and the other to the right..."
"The coordination and formation of the above series of movements are the anatomical explanation of the formation of the human body's hip movement."
"If we analyze it from the perspective of the "hip delivery" technical movement of sports anatomy - as a way of human body movement, running is a regular movement. When running, the legs and feet alternately jump off the ground. In some parts of the movement, Instantly, both feet are off the ground at the same time, and the legs are flexed upward. Therefore, the actual function of "hip sending" is to make the body's center of gravity jump forward, which can further increase the forward distance in the horizontal direction. In running, the hip sending action often occurs , especially when professional athletes perform running movements, this technical movement requires the coordination of the forward movement of the body's pelvis and the forward movement..."
"Therefore, from an anatomy point of view, "hip forwarding" can reduce the ratio of pitch and thrust and help improve the cadence. During running, hip forwarding can cause the pelvis on the side of the swinging leg to produce internal rotation, causing the hip of the supporting leg to rotate backward. The speed and amplitude of paddling and back extension become faster. The speed generated by the hip extension of the supporting leg and the inertia of the running speed during the journey also compress the time for the knee joint of the landing leg to make concessionary contraction, speeding up the
By increasing the speed of backstroke after landing, the body's center of gravity quickly surpasses the vertical support point and enters the rapid backstroke and hip extension stage..."
"In this way, the 'hip sending' technique can actively adjust and utilize external forces in each stage of running, shortening the time of each action, thereby increasing sprint speed."
"Now let's talk about the last aspect." Su Shen took the drawings he had made and continued to explain: "Analysis of the "hip sending" technical action from the perspective of sports biomechanics."
"The preparatory action for sports is the body's preparation for back-pedaling, and the size of the back-pedaling force is a direct response to the athlete's muscle capacity. However, the actual effect of the back-pedaling does not entirely depend on the size of the back-pedaling force. The technique and technique of the back-pedaling also determine the strength of the back-pedaling force. The actual effect of pedaling will affect the movement of the pelvis and legs. If the pelvis cannot move forward and the thighs cannot be too high, then the support force will deviate from the center of the human body, causing an inconsistency between the direction of people's movement and the horizontal component of force. If you don't coordinate, you won't get the desired results..."
"The more powerful the leg swings forward, the longer the muscles behind the thighs will be stretched. The muscles stretching backward can accumulate force for the forward movement, which provides good conditions for the next step of back kicking. Thigh stretch Later, the pelvis will tend to move forward of the body. The stronger the back kicking action, the faster the leg swing speed. The stretching of the back kicking action can promote a balanced state of the pelvis, while the alternation of the legs ensures that the pelvis moves forward and ensures the stability of the body movements. Basic conditions……"
"In this way, in terms of sports biomechanics, hip extension can save exercise energy. After hip extension is completed, the back pedaling posture maintains the correct position, which can quickly reduce the pelvic activity area to a large extent."
"You all understand, first grasp the human anatomy, sports anatomy, and sports biomechanics. Then we can figure out which of these five domestic arguments are wrong, which can be learned, and which must be Ban it." Su Shen said from above. The people in the small team, because Su Shen had given them a better knowledge base, could barely keep up.
The rest of the people, it sounds like they are... like listening to the heavenly book.
Absolutely, I know every word, and after spelling it together, I am completely confused about its meaning.
But these people could still listen, nod their heads, and ask questions.
Who are these people?
A top student?
Are top students still coming to run these days?
During this period, it was indeed because my grades were not good enough that I chose to pursue sports. As a result, not to mention the scientific knowledge system, even the basic nine-year compulsory education system was somewhat lacking. In this case, there is naturally no understanding and application of scientific knowledge and scientific systems. Just like future soldiers, the improvement of knowledge quality and knowledge structure is an inevitable trend.
Don't look at those European and American athletes who are not very good.
But those who can really get through are all experts in this field, with serious university degrees.
In this regard, first of all, there are not many universities in China that have this kind of kinesiology major. Secondly, it started too late, and the quality of students and teachers is not good enough. The chain effect has led to the current "deteriorating" and "vicious cycle."
Therefore, Su Shen still remembers that when Randy and the others came over, the first thing they did was to familiarize themselves with this knowledge. Not only did the coaches have to be familiar with it, but the athletes were also required to master it. Only in this way can such communication efficiency and training efficiency be achieved. peak.
It seems like a waste of time, but in fact, in the entire training system, it will get twice the result with half the effort.
This is why Su Shen needs them to memorize relevant theories first every time.
Mastering the theory, you will roughly know why you are doing what you do, and you will be able to provide better feedback and reflection.
Rather than simply running, running, practicing.
But in fact, I couldn't say anything, and I couldn't explain anything clearly.
But there are also people here who are very wise, such as the "older young people" who work and rest. This kind of opportunity is simply what he dreams of.
I really wanted to study before, but I had no chance at all. Now that I have it, I can't let it go.
Although he was born as a farmer, he was hard-working and practical, and he was the fastest among them to memorize it.
Soon I took the time to join Su Shen's small team to "observe".
Su Shen didn't say anything when he saw it. On the contrary, he was very positive about his attitude towards work and rest.
And you can see that even Ningdebao is taking notes from time to time, constantly thinking and reflecting on these knowledge points.
Yuan Guoqiang came over curiously and was shocked by this scene.
because……
The level of detail and thoroughness of this technical detail, throughout the country.
Even him.
This is also the first time that I have met someone and explained things so clearly and clearly.
