He is now considering his physical fitness in the second half.

Have your own unique understanding.

that is……

The reaction speed is really turtle.

It's only 0.219s seconds again.

If this reaction is 10 years later.

The designation will be teased by someone - back of the ears.

Rogers's startup response was not very good, only 0.191s.

In addition, he was already among this group of people...

A startup feature that is not outstanding at all.

It causes him to fall behind when he starts.

The reaction to work and rest was 0.147s. At the start, his hip lifted up moderately.

This is to ensure that the legs have enough room to exert force and maintain body balance.

The moment you push your feet to the ground.

The center of gravity shifts smoothly forward and upward.

The arm swing range gradually transitions from a larger initial stage to a more stable rhythm.

When swinging forward, the height of the arm is slightly lower than the shoulders. When swinging backward, the arm should be straightened as much as possible to coordinate the arms and legs.

You must find the rhythm of starting to accelerate as soon as possible within four steps.

Lao Zhang's reaction was unspeakable, 0.129s, although he only ranked second in this game, he was slightly worse than Carter.

However, Carter may not be able to perform such a reaction in 10 games.

Almost every game can be found on Lao Zhang.

Seven or eight out of 10 games can be played.

That stability is incomparable.

After rushing out, Zhang Peimeng immediately stood at four points and turned a few steps ahead, gradually increasing the length of the step.

Every step is testing and finding the best combination point of force and step frequency.

Keep the head low.

It is convenient for you to start the second stage.

The moment Bolt started, although the upper body was huge, its movements were coordinated. When swinging, the angle between the upper arm and the forearm changed smoothly, even smoother than before.

This year's winter training is definitely not vague.

When swinging, the shoulders are slightly rotated.

When swinging back, use the inertia of the body to fully extend the arms.

Bolt's startup efforts this year may be better than any previous year.

This is the first time in his career that he has been highly self-disciplined and hardworking.

Ingredients that are harmful to the body's sports performance.

It was the first time in my career that I was hit to the lowest level.

This made him feel painful even though the process was.

The whole person ran.

But I feel that my body is particularly controlled.

Extra lightweight.

His weight and pure muscle ratio have increased a lot.

Has reached an ideal value that Mills thought he should achieve.

But, very helpless.

No matter how good he performs here, he will not receive much attention.

Because at this time point, you should not be a domestic audience, even if you are a foreign audience...

They also know when it starts.

Who should be seen.

Not to look at Bolt.

It's not about Powell either.

Not Gatling.

Not Guy either.

Only Su Shen is watching.

There was only one red figure on the runway.

Su Shen heard the gunshot.

The bent arms push the body and swing forward and back quickly and forcefully. When swing forward, the joints of the hand are close to the chin. When swing backward, the arm is straightened and forcefully lowered. This method of swinging the arm effectively drives the body forward and accelerates.

In terms of legs, the calf quickly folds and swings forward, the soles of the feet are actively swaying the ground, and the steps are very fast. The first three steps after the start establish a golden three-step rhythm.

The characteristics of the lower body force exerting force is that the legs and hips are synergistically exerted, the legs are flexed and extended quickly, and the buttocks muscles are tightened and exerted, concentrating the strength and bursting in the starting direction.

Su Shen started the reaction 0.133s, and it can be seen that he was still effective in the specialized training for starting with the gun. This made him seem to be easier to run through the 0.130 segment.

The start of this segment is actually very fast.

Perhaps it is not as good as those monsters that activate reaction talent.

But in a better condition, you can reach 0.130.

Even broke through 0.130.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! That is not impossible.

During the starting stage, through the precise regulation of its own nervous system, the teres major muscle can quickly generate powerful contraction force, causing the upper arm to retract quickly in the sagittal plane.

Coordinate with shoulder muscles such as the deltoid muscle to stabilize the shoulder joints, providing a stable fulcrum for the arms to swing forward, thereby effectively transmitting strength and promoting the body.

The size and speed of its contraction depend on factors such as the type of muscle fibers, muscle cross-sectional area, and the strength and frequency of nerve impulses.

These aspects.

Su Shen is much better than before.

It's much better than the previous life.

I saw that he caused the shoulder joint to rotate externally at the moment of starting. This external rotation is in harmony with the adduction of the teres major muscles and other actions, which can fine-tune the swing direction of the arm, making the swing of the upper limb more in line with the principles of mechanics.

This helps the body to get a reasonable initial speed and forward momentum at the start.

The upper limbs can stretch the fascia and muscles on the back at the moment of starting, just like pulling a full bowstring.

The sense of power contains the golden beauty of the human body's movement curve.

The elastic potential energy generated by this stretching will then conduct downward along the body's dynamic chain.

Later, the gluteus maximus, quadriceps femoris, etc. activate the contraction force one by one.

Also, when the arm swings back quickly, a reaction force of equal magnitude and opposite direction will be generated.

This reaction force is transmitted to the pelvis and lower limbs through the rigid structure of the body such as the chest and spine. At the same time, the rapid back swing of the upper limbs will stretch the muscles such as the lats dorsi and connect the upper and lower limbs, so that these muscles can store elastic potential energy.

And when these elastic potential energy is released.

It will collaborate with the contraction of the lower body muscles.

It will increase the strength of lower limbs to push the ground.

In this way, there is a relationship of interaction inhibition and coordinated activation at the spinal cord level through the motor neurons of the upper and lower limbs. The rapid and powerful movement of the upper limb muscles will activate the lower body motor neurons in advance through the spinal cord reflex pathway.

This enables lower limb muscles to enter a contraction state more quickly.

This will continue to improve the explosive power of the lower limbs.

In this way, with four points and one line standing up, plus three steps of gold.

Bang bang bang bang.

This is what Su Shen’s entire person is called display, what is the ultimate startup speed?

Six seconds and tens of billions of speed.

Not adulterated at all.

Three steps to pull Bolt and Blake who started quickly next to him.
