Chapter 1862 This is the way to surpass super cadence!!!
How could Bolt run so fast here?
No one expected that the big man's initial acceleration would be a problem, but as a result...
It doesn't seem to be a problem now.
At least it's not a problem for him.
This is a bit outrageous.
But there was only one person in the audience who was not shocked, and he was Su Shen, who was currently leading the fifth lane.
Su Shen has long divided Bolt's competition into stages and analyzed each ability countless times, and he knows exactly what kind of Bolt he will encounter at a certain stage.
Bolt may have some inner demons at the start this year, but his acceleration is absolutely unambiguous.
You can even reach the strongest level in your career.
Su Shen is waiting for him here.
Sure enough, Bolt started to show its strength.
Who would have thought that the showdown between Bolt and Su Shen would begin so early.
Even though Powell seems to be in second place now, Su Shen knows that there is a high probability that Powell will not be able to run ahead of Bolt this year.
Therefore, with this shot, it can be said that my opponent at the beginning was Usain Bolt, not anyone else.
Su Shen's figure began to lean forward, and then slowly became smaller.
During the connection process, the athlete's overall movement speed will increase due to changes in the swing movement of the lower limbs.
Tilt from the upper body to the lower body, from the upper body down, and from the bottom up.
Above the chest, the upper body exhibits a less obvious forward leaning posture during activity.
During this process, the athlete's body shape must be maintained at a high speed and amplitude, and must have strong waist and abdominal strength to support it. It just so happens that this is what Su Shen lacks the most right now.
Randy looked at it, he knew what Su Shen was going to do, and he might be the one who knew the most about Su Shen's plan.
From the beginning, he also thought that Su Shen was crazy, but by helping Su Shen realize it step by step and overcome difficulties step by step, they had already thought of a theoretical possibility.
But only in theory.
Theoretically, if you do these things well, you will have a chance to compete with Bolt.
Are you really okay?
Is it really feasible to continue upgrading in the acceleration zone?
Regarding front side mechanics, Su Shen became more and more active during the acceleration phase.
Before Su Shen was about to complete this new ultimate move, he also asked his laboratory, and the result was--
The stiffness of the limb may also determine the frequency of jumping and running movements. According to this model, the human body is described as a massless spring with a particle. When jumping or running, the stored and available elastic potential energy will be wasted.
When jumping at the appropriate frequency and above, the rigidity of the leg springs increases, and the body always behaves like a simple elastic body system. But when it is greater than the appropriate frequency, the time for generating muscle force is shortened due to the reduced contact time with the ground.
Increase metabolic energy.
In other words, when the frequency is greater or less than the individual self-selected frequency or suitable frequency, energy consumption will increase.
So, the question is, how to change the stored and available elastic potential energy from being wasted to minimizing waste or even not wasting it?
How to make this frequency neither greater nor less than the individual self-selected frequency or appropriate frequency?
Achieve an optimal energy consumption state?
This actually involves a deeper subject in kinematics, but that is a matter for later. What Su Shen is talking about now is how to solve these immediate problems.
The method he adopted is - since walking with long stride length and low cadence frequency will increase the contact force between the person and the ground, while short stride length and high cadence frequency require the limbs to accelerate more frequently. When controlling the speed to perform cadence
When changing, the mechanical power will be quantified into two parts. The external power causes the body's center of gravity to rise and accelerate, and the internal power causes the limbs to accelerate relative to the center of gravity. When the stride frequency increases, the external power decreases, while the internal power increases, but the external power
It cannot be reduced infinitely and must be able to meet the requirements of movement.
So how can Su Shen, who has already upgraded his super cadence, continue to speed up his acceleration ability and even his entire future?
The answer is obviously ready to come out.
Su Shen had already vaguely felt this answer at the beginning of this season.
After changing his feet and creating a new rhythm, he has discovered the fact that he can still be stronger.
This is something that the experience of the previous life cannot give him.
because……
In this life of his.
Grow taller.
Become stronger.
More professional muscles.
The stride length and physiological conditions of the legs have also become better.
While he has been practicing hard, scientifically developing, and deliberately maintaining his talent for cadence, he has actually fallen into the misunderstanding of "empiricism". He always tries his best because of the inherent experience and knowledge in his mind, and the way he used it in his previous life.
Take the "fast lane".
As everyone knows, this somewhat ignores another aspect of change.
Especially after the addition of front side mechanics, his current body is already somewhat unbalanced.
This is what Randy and Su Shen said in the discussion - the first thirty meters were too fast, causing the running speed to be faster on the way in. In this way, the originally maintained stride can easily lead to the center of mass falling forward and the center of gravity.
Easy to fluctuate back and forth.
This is great for hip joint angle and flexibility.
Ankle joint stability and stress range.
They are all huge tests.
What else would Randy say:
Any improvement in this part will go beyond the body's ability to excel and will require additional talent to supplement it.
The championship model shows that if you increase the size further, it will exceed your physical limit, and I am afraid it will have the opposite effect. Not everyone can have Guy’s huge hip displacement, and not everyone can be like him.
, although he is only 180 meters tall in shoes, he can release hip width and angles that even a 1.9 meter player may not be able to match.
From Randy's point of view, these are all talents.
At present, it is difficult for science to help development.
But...
Actually it is.
Incorrect.
Because this is what Su Shen has been doing.
He had been collecting these so-called talents a long time ago in his previous life. What are the talents they possess?
This chapter is not over yet, please click on the next page to continue reading! Can it be refined scientifically?
For example, Powell has extremely developed calf explosive power and is better able to maintain explosive power during startup.
For example, Gay's hip displacement is far beyond what his body should be capable of.
For example, Blake, why is his endurance talent so good and his acid resistance so strong?
How is that done?
Is it really just because of "talent"?
Or is it that after they have materialized, certain muscles and certain joint flexibility have been developed since childhood that they are not clear about?
He doesn't deny talent, but just talking about talent, Bolt can't open it for ten seconds.
Tracy McGrady will never be able to become Jordan, let alone Jordan, even less talented than Kobe Bryant.
There must be something that I haven't caught yet.
He thought about it for many years, and after collecting a lot of information in his previous life, he finally found some clues.
For example, Blake has been fond of cricket since he was a child. This sport had a great impact on his physical development in his teenage years. His muscle development also has a form that a simple sprinter does not have. Coupled with extreme hard training of muscles,
He has become a person who is obviously not as talented as Bolt, but even Bolt was embarrassed at his peak.
For example, Merritt, who just competed with Liu Xiang, has a gymnastics background since childhood.
Take Guy, for example. Guy has loved running around in the yard since he was a child. He can run around the wall alone for a long time without getting tired of it.
Do these habits develop and help their talents?
Summarize these seemingly irregular childhood habits and sports hobbies, and then transform them into special projects to see to what extent they will help.
For example, in this life, Su Shen paid great attention to the development of the flexibility of the body's ligaments and joints.
It is really painful to be unable to move forward in my previous life.
As a person who is troubled by his stride, and has missed the optimal development period of his body, he can only use his strengths and avoid weaknesses, and try his best to give full play to his best advantages. But if you think about it, Su Shen will be in Tokyo in 2021, let alone
If you have Guy's hip displacement talent, you can say that you can be better. Your hip displacement ability is better than your original, your hip joint flexibility is more developed, and your hip ligaments - such as iliofemoral ligament, femoral head ligament, pubic bone
ligaments, ischial ligaments and orbicular belts, etc.
Can it be further enhanced?
Isn’t it better if you have developed since you were a child than if you never paid attention to development before?
Is it true that, if developed since childhood, it will become the so-called better physical talent in adulthood compared with people of the same height and condition?
These.
These are all things Su Shen considers.
Especially after the reopening, although he still takes the "fast track" based on his own experience, after all, his goals and ambitions do not give him much time to waste. But these original weak muscles, such as the soleus, have become
Strengths, such as the displacement load strength of the hip, the load-bearing capacity of the hip, and the flexibility of the hip, have all been scientifically developed since childhood and have become a huge boost.
Well, now we just need to cash it out.
These talents are the result of using up the "fast lane experience" from the previous life.
Reliance on finding a new path.
After Su Shenhui made major technical changes and changed his feet this year, he felt something completely different from the previous life.
Because.
Previous life.
He came here.
It has already come to an end.
Due to the degree of physical development, there is no way ahead.
But what now?
Following this approach, he clearly felt that there was still a way to go, and even this was far from his limit.
Randy said that it is very difficult to be like Guy. There is no so-called talent, it is simply impossible. Even if you tear your balls to pieces, it will be useless.
Su Shen's answer at that time was - how would you know if I would be involved if you don't try?
Because this body and the change of feet gave him a sense of potential that was better than imagined.
If I can move the speed in the acceleration zone more to the mid-run and top speed zones.
There should still be potential for me to tap into my future.
Maybe it was just a joke at the time, and Randy didn't take it seriously. After all, some people's talents are unparalleled.
Challenging the theory of talent is, at present, still a "very nonsense" and "very mysterious" thing in the track and field world.
But Su Shen has discovered the clues, and as before, he took the initiative to use himself as "data" and "guinea pig" for experiments. There is no way to conduct sports experiments in this area, and no one can do it except him. People are willing to
All to no avail.
He can only work harder if he can.
So Su Shen made the following changes here:
Keep your chest and abdomen tilted forward.
And with strong waist and abdominal strength as a guarantee, it provides a fulcrum for the lower body to exert force, and also prepares a channel for the body's trunk to transport energy up and down.
After doing this and making the lines of force and energy channels clear, Su Shen immediately raised his legs and prepared to break the situation.
Why did Randy say that after adding front side mechanics, his body is now somewhat unbalanced?
Why is it that the first thirty meters are too fast, causing the running speed to be faster on the way in? This should be a good thing, but on the contrary, it makes the original balance-maintaining stride easily cause the center of mass to fall forward, and the center of gravity to fluctuate back and forth?
Randy's suggestion is to start with the hips and ankles.
But it’s just an idea. Randy still needs to study and investigate how to do it specifically.
Fortunately.
This is the reopened Su Shen.
He just needs Randy to ask him questions.
For the rest of this life, he has to deal with it by himself.
How to do it?
Su Shen here causes the hip joint to begin to increase the range of internal rotation and pronation.
The hip movement creates favorable conditions for the high leg raising movement, and the inertial force generated by the accelerated movement of the swinging leg directly acts on the supporting leg, helping to increase the back kicking force and reduce the back kicking angle.
The lift angle of the body's center of gravity decreases accordingly.
As the back pedaling angle decreases, the displacement of the center of gravity in the horizontal direction increases.
Is this enough? Of course not.
With the cooperation of the swinging leg actively swinging forward, the supporting leg begins to actively extend the hip joint after touching the ground. Before landing and throughout the supporting process, the stretching of the supporting leg is a continuous process of exerting force. Try to get the "hip" as much as possible.
"Internal Buffer".
This chapter is not over yet, please click on the next page to continue reading! This is to allow yourself to be in. During the support process, regardless of the supporting leg or the swinging leg, the movement of the thigh is in a state of acceleration---deceleration.
Using a good "hip delivery" technique can speed up the shearing and twisting, and make the body's displacement speed faster.
Is this enough? Not enough.
Then the hip is actively moved, causing the pelvis on the side of the swinging leg to produce internal rotation, speeding up the swinging leg, and also speeding up the active ground-grabbing action of the supporting leg. This shortens the time for the supporting leg to make concessionary contractions, allowing the
The speed generated by the hip force and the inertia of the running speed make the body's center of gravity quickly surpass the fulcrum of the supporting leg, making it easier to pass the vertical support stage faster and shortening the time for the supporting leg to perform isometric contraction.
What are these for?
Then the femoral head ligament is also driven.
This is because the femoral head ligament is in the shape of a flat triangle and has a certain degree of elasticity, which can prevent femoral head damage caused by excessive movement during abduction or adduction of the femur. In addition, the blood vessels and nerves wrapped by the femoral head ligament can also be damaged.
Effective protection to avoid pain and discomfort caused by bone damage.
The two ends of the femoral head ligament are respectively attached to the recess of the femoral head and the acetabular notch. This connection method can tightly combine the femoral head with the acetabulum, ensure that it is in a normal physiological position, and can maintain the balance and pace of the human body.
state.
Adjust the turn belt.
The main function of the orb belt is to prevent the prolapse of the femoral head. Under normal circumstances, it is close to the outside of the synovial layer of the hip joint through its annular structure and plays a role in stabilizing the hip joint. In particular, the orb belt resists joint traction in the neutral position.
, similar porous devices stabilize the hip joint from the adverse effects of edge loading, especially during extreme hip flexion and extension.
Of course this is just the basis.
The most important ones are the last few.
This is something Su Shen couldn't tell Randy.
Because of the following kinematic terms.
There is none now.
The first version will not be released until 2019.
Therefore, it is impossible to apply it to kinematics now.
Therefore, it is simply impossible to strengthen and utilize it, let alone do scientific development in advance.
But Su Shen is the one who reopens.
Naturally, it is not subject to this restriction.
Then be the first person in this era to open these ligaments and bring them into sports.
Anyway.
It doesn’t matter whether it’s the previous life or this life.
Have been doing this all the time.
Mobilize the iliofemoral ligament.
The iliofemoral ligament is located in front of the hip joint. It starts from under the anterior inferior iliac spine, separates outward and downward in a "herringbone" shape, and ends at the intertrochanteric line of the femur. It is one of the strongest ligaments in the human body and can limit excessive extension of the thigh.
, prevents the pelvis from tilting back too much and plays an important role in maintaining the upright posture of the human body.
Mobilize the pubofemoral ligament.
The pubofemoral ligament is triangular in shape. It originates from the iliopectineal eminence, superior pubic branch, obturator membrane, etc., moves obliquely outward and downward, and migrates to the hip joint capsule and the medial part of the iliofemoral ligament. It can limit the abduction and external rotation of the thigh.
.
Mobilize the ischiofemoral ligament.
The ischiofemoral ligament is located behind the hip joint capsule. It originates from the back and lower part of the acetabulum, goes outward and upward, and passes behind the femoral neck. Some of the fibers migrate to the orbicular belt, and the other part ends at the ligament at the root of the greater trochanter of the femur.
Limit thigh adduction and internal rotation movements.
And these three hip ligaments.
Su Shen can confidently say that in the whole world, he is the only one who has known about it since he was a child and has been scientifically trained and developed it since he was a child. The rest of his contemporaries, I'm sorry, you don't even know that these things exist here.
Not to mention utilization and scientific development.
So, is this considered one of Su Shen’s physical talents?
This is why Su Shen said that during winter training.
Because he has knowledge and scientific trump cards that athletes of his generation do not possess.
Even if you are Usain Bolt, the saint of track and field, your talent in this area is not as good as mine, which has been developed scientifically since childhood.
And after so many years of development, it is just for now, to push ourselves to the limit and make breakthroughs.
Usain.
Take a good look.
This is one of the Olympic gift packages I’m preparing to give you.
PS: I am disabled with one hand, so it is so slow. There is no way, it will take more than double the time, ugh.
I really feel like crying without tears.
However, had anyone anticipated Su Shen’s professional scientific development talent?
To fight against Bolt, you naturally need to have talents and attributes that Bolt doesn’t have. You guys are right, right? In 2019, it’s just about being ruthless or not, hehe~~~
