The Su God of the Reopening of the Sports Arena

Chapter 2252 Super Start Acceleration Conversion! New Explosion Point is Coming

In short.

The core principle of Su Shen's seventh technical breakthrough lies in breaking the antagonistic relationship between vertical force and horizontal force.

Through the golden ratio of joint angles, speed adaptive tuning of muscle stiffness, and pre-programmed control of neural reflexes, a three-dimensional coupling system of "vertical energy storage-horizontal energy release-neural co-control" was constructed.

The innovation of this technical paradigm is——

Tensorization of force vectors: treat your own GRF as a vector field that varies in space and time.

The dynamic transformation of vertical and horizontal components is achieved through the temporal coupling of multi-joint dynamic chains.

Bidirectional flow of elastic potential energy: utilizing the “spring-mass” properties of the muscle-tendon system.

Stores vertical impact energy during landing.

It is converted into horizontal propulsive energy during the extension phase.

Advance prediction of neural control: Based on wind tunnel data and kinematic models, neural reflex pathways are pre-programmed to make muscle activation timing ahead of physical stimulation.

Shorten reaction time lag.

Targeted activation of energy metabolism: via motor unit threshold regulation and muscle fiber regional recruitment.

Achieve precise release of the phosphagen system in space and time.

To put it simply...

This theoretical system provides a new research paradigm for breaking the limit of human running speed.

Its core value lies in revealing the nonlinear coupling laws between biomechanical parameters, muscle synergy mechanisms, and neural regulation strategies. It proves that technical optimization can break through the inherent limitations of muscle type and body shape characteristics, providing a scientific basis for improving the speed of Asian athletes.

So let’s start showing.

All theory.

It only makes sense if it is demonstrated in reality.

Is this also the reason why Su Shen wanted to use himself as an experiment?
Because there is only myself.

He is the person who is most qualified to combine theory with practice in this era.

If you don't do it yourself.

Just sit back and enjoy the fruits of others' labor.

Then.

Wait until I am old.

I'm afraid I can also forgive myself.

Su Shen has already seen the way forward.

This is a crucial step in initiating and accelerating transformation.

it is done.

Just a smooth start.

It is enough to take yourself to the next level.

This is definitely not a joke.

Then.

let's start.

I am the ultimate experimental machine.

let's start.

How to realize the physical essence of force vector coupling mentioned above?

The lower limbs are regarded as a rigid chain, and a "backward-leaning kicking" posture is formed by adjusting the plantar flexion angle of the ankle joint and the extension angle of the knee joint.

This posture increases the plantar flexion angle of the ankle joint and improves the extension torque; it adjusts the extension angle of the knee joint, increases the vertical component, and provides a larger load for elastic potential energy storage, thereby converting the vertical elastic potential energy into horizontal propulsion kinetic energy.

Then there is the critical angle model for vertical force-horizontal force conversion.

How to transform reality?

How to activate the golden sequence degree?

Look at Su Shen.

Vertical force is redefined as a carrier of elastic energy storage and a trigger signal for neuromuscular activation.

It can be assumed that the vertical impact force at the moment of landing is transmitted to the central nervous system through the plantar pressure receptors, triggering the feedforward neural control mechanism, so that the plantar flexor muscles of the ankle joint are in a high tension state when they touch the ground, reducing energy dissipation.

At the same time, when the angles of the hip joint, knee joint, and ankle joint meet the golden angle sequence, the force conversion efficiency coefficient reaches its peak, achieving efficient conversion of vertical force to horizontal force.

How to do timing control?
Look at Su Shen.

By adopting a stepped kicking and stretching sequence, the hip, knee, and ankle joints exert force in turn, making the ground reaction force curve show a "three-peak superposition" feature, thereby increasing the total impulse.

Wave-like superposition of three-joint extension.

excitation.

How to do stiffness tuning?
Look at Su Shen.

Muscle stiffness is adaptively adjusted as the contraction speed changes, forming a nonlinear resonance effect with the stretching frequency, thereby improving energy transfer efficiency.

Nonlinear resonance effect.

activation.

How to do reflex control?
Look at Su Shen.

Changes in head posture trigger dual-pathway regulation of the vestibular-spinal reflex, which controls the head position and trunk posture and ensures the stability of the direction of the ground reaction force vector.

Otolith organ pathway activation.

Semicircular canal pathways.

But this is not enough.

After all, theory is just theory.

How to convert in practice.

Specific techniques or muscle dominance are also required.

In sprinting, Su Shen wants to achieve the desired effect. The seventh step is to use vertical force and horizontal force in a sophisticated way,
Behind this, specific muscle and joint combinations play an indispensable core role.

These muscles and joints do not work in isolation, but rather through precise coordination.

Only by deeply integrating the principles of mechanics and physiological functions can we jointly push the human body to reach its speed limit.

Su Shen’s choice is——

Triceps surae and ankle joint.

Most of the points he emphasized before were focused on the ankle joint.

Its significance.

That's right here.

Both require strong ankle intervention.

Tensor decomposition of force vectors and joint coupling models are required.

The space-time transformation mechanism of elastic potential energy is required.

The dual role of vertical force: the dialectical unity of impact load and energy storage medium is needed.

Impact loading-induced muscle preactivation is required.

Critical angle model for vertical force-horizontal force conversion, required.

Golden sequence degree, required.

The wave-like superposition of three-joint extension is necessary.

Stiffness tuning, required.

Reflex regulation, required.

Spatiotemporal targeted release of the phosphagen system is required.

The "sarcomere-tendon" relay model of energy transfer is required.

Mathematical modeling of vector coupling and derivation of critical conditions are more needed.

……

But ankle joints alone are not enough.

It also requires the help of the main muscles.

Su Shen’s choice here is.

Triceps surae.

That is, the gastrocnemius and soleus muscles, which he was least proficient at in his previous life.

He will use this and the ankle joint to form an important functional unit that converts vertical force into horizontal propulsion force.

boom.

At the moment of landing in the seventh step, a strong vertical impact force acts on the foot.

The triceps surae bear the brunt of the damage.

Stretched like a strong spring.

At this time, the increase in the plantar flexion angle of the ankle joint is optimized from the conventional angle to 45°, which significantly increases the force arm of the triceps surae. According to the principle of leverage, the extension of the force arm can generate a greater torque under the same pushing force, effectively improving the pushing effect.

When the triceps surae is lengthened, the muscle-tendon complex stores a large amount of elastic potential energy.

As the push-off movement progresses, this elastic potential energy is efficiently released during the concentric contraction of the muscle.

In the late extension phase, the ankle joint rapidly plantar flexes and the triceps surae contracts forcefully, converting the stored elastic potential energy into horizontal kinetic energy that propels the body forward.

In this way, Su Shen wants to significantly increase the horizontal propulsive force contributed by the calf triceps in the seventh step compared to the previous method.

Its elastic potential energy recovery rate is as high as 27.6%.

Then it will be greatly improved compared to the original level.

This is... the key source of power for horizontal force generation.

In addition, the structural characteristics of the ankle joint also provide support for this process.

The flexion and extension movement of the ankle joint, driven by the triceps surae, can accurately control the direction and strength of extension.

During the seventh step, the rapid plantar flexion of the ankle joint not only increases the force of pushing off the ground, but also optimizes the direction of the force, converting more force into horizontal propulsion and reducing the ineffective loss of energy in the vertical direction.

As the main muscle group on the front of the thigh, the synergy between the quadriceps femoris and the knee joint is crucial for the combined use of vertical and horizontal forces.

In step 150, the knee extension angle is adjusted to °. This angle setting makes the force direction of the quadriceps muscle closer to the femoral axis.

Compared with the traditional angle, this adjustment reduces the vector loss in the force transmission process, allowing the vertical force to be converted into horizontal force more smoothly.

The quadriceps muscles play a critical role in transmitting force during knee extension when vertical forces are applied to the body.

The contraction of Su Shen's quadriceps at this time not only drives the extension of the knee joint, but also, through coordination with other muscle groups, effectively converts the vertical force into horizontal force that propels the body forward.

During the extension process, precise control of the force direction and strength of the quadriceps ensures maximum output of the horizontal force component.

At the same time, the stability of the knee joint also depends on the strong contraction of the quadriceps.

In the seventh step of high-speed running, the knee joint is under tremendous pressure and impact. The quadriceps maintain the stability of the knee joint by maintaining appropriate tension, preventing sports injuries caused by uneven force, and providing a stable structural foundation for the efficient conversion of vertical force and horizontal force.

In addition, the coordinated contraction of the quadriceps femoris, triceps surae and other muscle groups forms a power chain for the lower limbs, further enhancing the strength and effect of pushing and stretching, allowing the body to obtain greater horizontal acceleration.

The muscle I was least good at before.

just now.

It has become one of Su Shen's strongest muscles.

This is what reopening is all about!
It's not over yet.

There is also a combination of gluteus maximus, hip joint and core muscles.

This will improve the overall power enhancement and balance maintenance hub.

The gluteus maximus, one of the largest muscles in the human body, together with the hip joint and core muscles, constitutes a key combination for improving overall power and maintaining balance in the seventh step of running.

During the seventh step, the hip flexion angle increases slightly to 95°. This angle change increases the force arm of the gluteus maximus in the later stage of push-off and changes its direction of force.

The contraction of the gluteus maximus not only generates a powerful backward pushing force, but also, through the coordinated movement with the hip joint, produces a horizontal "bending effect" under the action of vertical force, just like the second fulcrum of a lever, providing additional horizontal propulsion for the body.

Next is...the core muscles including the rectus abdominis, transverse abdominis, erector spinae, etc., all play an important role in maintaining body balance and stability in the seventh step.

When the body leans forward at an angle of 60°, the balance between the horizontal component of gravity and the supporting reaction force places extremely high demands on the core muscles.

The coordinated contraction of the rectus abdominis and erector spinae muscles generates a powerful torque to counteract the body's rotational tendency, ensure the stability of the body posture, and enable the ground reaction force to push the body forward in the correct direction.

In addition, the core muscles also form a bridge for power transmission with the gluteus maximus and hip joint. During the extension process, the stable contraction of the core muscles helps to efficiently transfer the power generated by the lower limbs to the trunk, thereby pushing the body forward.

The close cooperation between the gluteus maximus, hip joint and core muscles not only improves the overall power output, but also ensures the body balance and movement coordination during running, so that the vertical force and horizontal force can be better coordinated on a stable basis, helping... Su Shen to reach a higher speed in the seventh step.

The above-mentioned muscle and joint combinations do not operate independently, but cooperate and work together to form an organic whole.

In the stretching process of the seventh step, each link is closely connected, starting from the elastic energy storage and efficient stretching of the calf triceps and ankle joints, to the force transmission and direction optimization of the quadriceps and knee joints, and then to the overall power enhancement and balance maintenance of the gluteus maximus, hip joints and core muscles.

Just like this kick.

When the calf triceps muscle exerts force to extend, the force it generates is transmitted to the knee joint through the bones, and the quadriceps muscle then contracts in coordination to further enhance the extension force and adjust the direction of the force.

At the same time, the gluteus maximus and core muscles are activated synchronously, providing a stable foundation and strong support for the power of the lower limbs.

The synergistic effect of Su Shen's combination of multiple muscles and joints enables vertical force to be gradually converted into horizontal force at different links, and energy is efficiently utilized during the transmission process, reducing losses.

Then cooperate with the neuromuscular control level.

The central nervous system precisely regulates the sequence and strength of movement of these muscles and joints.

Through complex nerve reflexes and signal conduction, it ensures that each muscle exerts force at the right time, and each joint moves at the optimal angle and rhythm, achieving the perfect combination of vertical force and horizontal force.

Finally helped Su Shen break through the speed limit in the seventh step.

Showcasing outstanding athletic performance!

will.

Abnormally smooth.

Smoother than ever before!
Su Shen uses the combined use of vertical force and horizontal force in the seventh step of running.

It is the result of the coordinated work of multiple muscles and joints.

These muscles and joints play a key role in elastic energy storage, force transmission and transformation, overall power enhancement and balance maintenance through their unique physiological structure and mechanical properties.

Their synergy.

This constitutes the core mechanism for breaking through the speed limit at present.
