Maximize impulse integral score!

The impulse J =∫Fdt, which represents the accumulation effect of force in time. According to Sushen’s experiment, the maximum impulse integral value at the 42° rear pedal angle is about 230N·s, because at this angle, factors such as the increase of horizontal component force and the action time of force have reached an optimal equilibrium state.

This 42-degree rear pedal angle.

This is the new changes that Su Shen has made this year!

Because.

Maximizing the impulse integral point value can make the four-point connection of Su Shen more powerful.

The four-point connection line is stronger, which means...

The output of the hip extensor group will be improved!

At this angle, Su Shen released power of 2800W in the pedal and extension stage, and the hip extensor groups such as the gluteus maximus, biceps femoris, etc. within 50ms, which is due to the contraction characteristics of the muscles and the regulation of the nervous system.

Its nervous system will quickly recruit a large number of motor units, causing the muscle fibers of the hip extensor group to contract rapidly in a synchronous manner, generating huge power in a short period of time, thereby outputting high power and providing powerful power for the rear pedal.

Not finished yet, then...

It can release the elastic energy storage of tendons explosively!

Tendons such as Achilles tendon have good elasticity. In the early stage of stretching, part of the energy generated by muscle contraction will cause the Achilles tendon to undergo elastic deformation and store it.

When the rear pedal reaches a certain stage, the Achilles tendon will rebound quickly, release the stored elastic potential energy explosively, superimpose it with the force generated by the active contraction of the muscles, further increase the rear pedal force, increase the power output of the hip joint, and help athletes obtain greater acceleration at the moment of starting and achieve faster start.

The above changes.

It is to better release the elastic energy storage of the tendon!

This step is actually outrageous.

Although Su Shen’s reaction was not the fastest, it was not slower now, 0.137s, steadily.

So what if Bolt was created by Mills for a new bipedal pressure center migration trajectory?

So what if Mills arranged better joint torque power for Bolt?

Even if Bolt's hamstring centrifugal-centripe contraction conversion efficiency reaches 0.85-0.92, which is significantly higher than that of ordinary athletes...

So what?

All of this was expected by Su Shen.

Nothing beyond expectations.

Besides, Bolt is still too tall and cannot exceed the body's straight arm drive limit without a bent arm start.

Then that is.

Although it has improved, it still cannot even compare to Carter's start after the breakthrough.

That's the case.

How could it be possible to fight Su Shen?

Because even if the four-point asymmetric support of both knees and hands is used to reduce the center of mass of Carter.

Now.

They are all completely inferior to Su Shen.

Even if the pressure center is preset, it is still blown by Su Shen’s swinging phase adjustment.

So.

What else can I fight with Su Shen?

Precise joint angle control?

Can you withstand the adjustment of Su Shen’s moment of inertia?

Yes Yes.

Carter has taken all these steps very well.

What is the front leg knee angle of 105°-110° to avoid excessive flexion and delayed centrifugal contraction of the quadriceps femoris.

What is the hind leg knee angle of 130°-135° to maximize the elastic potential energy reserve of Achilles tendon.

What is the dorsiflexion angle of the ankle joint, 25°±2° for the forefoot and 15°±2° for the rear foot, and "preloading" is achieved through precontraction of the plantar flexor muscle group.

All are very good.

It has indeed greatly improved its startup ability.

that is……

There are different levels between people.

Then between technology and technological changes.

Of course there will be grading.

Carter and Bolt both made good changes.

They also took the path of scientific optimization of their own activation.

They are all on a new path of scientificization.

that is……

When they just started riding their bikes on this road.

Su Shen.

Already on this road.

Started a supercar.

No.

Now it's racing.

Bang!

Step 2.

Su Shen strongly suppressed Bolt and Carter!

The long-awaited startup burst.

That's now.

All the previous ones lay the foundation for this place.

Of course, this is just a node.

But this node.

It's a big node.

Su Shen’s plateau competition optimizes its horizontal component and vertical force.

It's all for this big node.

Make your body feel this way in advance.

certainly.

It is not easy to display it on the plain.

It doesn't matter.

It is not easy to do well on the plains.

Aerodynamics is also harder to control than plateaus.

but.

There are also times when it is easy to display on the plains.

For example.

Big wind gun.

Especially for games like this one.

After the wind speed reaches a limit.

Some operations that are not that easy to do in plains.

Not so easy to accumulate experience.

It's OK, too.

Show it.

This is why Su Shen chose this game.

It's because.

He had known about this shot for a long time.
