Because this increases the length of the athlete's own swing, thereby increasing the swing amplitude.

Especially now, his hip movements are becoming more and more exaggerated because of his exertion.

If you don't capture this with high-definition video camera, you can't see it with your naked eyes.

How to do it?

Su Shen gave the answer at that time - a larger range of joint movement allows the body to adopt more exaggerated movement postures during the swing, fully utilize the body's potential and further increase the swing amplitude.

It's obvious.

Bolt has joint flexibility in the hip.

Far more than the rest.

It will naturally allow him to use a larger range of hip displacement in the curved and diagonal hip delivery.

It will naturally allow him to raise his swing on the curve.

This is because muscles can contract and relax better during the swing, and the synergistic effect between different muscle groups is smoother. For example, in this frame, during the swing, Bolt's legs, glutes, quadriceps, hamstrings and other muscles are exerting force and relaxing in turn. Good talent can make these muscles work better at different stages and improve the efficiency and amplitude of swing.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Humans are such an animal. You can find that the gap between the top people in the industry and ordinary people is almost a species diversity.

Including Guy, his current coordination of muscles can ensure that the transmission of strength is more efficient. From the moment of pushing the ground to the swinging of the swing of the legs, strength can be smoothly transmitted between various joints and muscles, reducing energy loss, and thus increasing the swing amplitude.

From a biomechanical perspective, when the body's movement speed is accelerated or the movement intensity is increased, in order to maintain the body's dynamic balance, the right arm will instinctively make adjustments.

The principle of inertia makes the body need greater strength to change its movement state during acceleration. At this time, the angular momentum of the right arm increases, and the body can move forward stably by increasing the swing force and amplitude.

It's indeed a monster.

Change to the past.

I'm afraid I don't know how to resist.

But now.

Su Shen instantly entered a state of high concentration.

Running on the way starts entering.

This is a key area.

If it is not handled properly, it will definitely be a loss.

Su Shen immediately tightened his core muscles. This movement can effectively stabilize the central axis of the body and provide a solid foundation for subsequent force movements.

At this time, he increased his investment in his posterior muscles, using the gluteus maxillus as the main starting point for his strength, and with the powerful explosive power and stability of the gluteus maxillus, he began to effectively drive the posterior muscles to work together.

During the forward swing of the legs, the legs are folded highly, making the movement trajectory of the entire lower limb more compact and efficient.

From the perspective of biomechanics, this folding action can reduce the swing radius, increase the swing angular velocity, and thus increase the speed and strength of the forward swing.

These people...

It's really amazing.

Although this is the final.

Although the finals look like there are eight teams.

But in fact.

Only three teams are competing.

The overall level of these three teams is also higher, and the others are far behind.

What is the third art?

This is called the third art.

The things that the three people showed on the third stick were different. Each of them had extremely strong personal characteristics.

It looks great in the confrontation.

Run on the curve!

Su Shen uses powerful gluteal maximus to drive the posterior femoral muscles, fully leveraging the advantages of gluteal maximus as one of the largest muscles in the human body.

Of course, this is also his biggest advantage.

The huge power generated by the contraction of Su Shen's gluteus maximus can be efficiently transmitted to the posterior femoral muscle group, making the dynamic chain of the entire lower limb more smooth.

This way of exerting force not only keeps the legs highly tight during folding, and does not loosen.

And, through precise muscle control.

It can also form the smaller folding angle that is most needed during the run.

The formation of this included angle can greatly reduce the swing radius. According to the law of conservation of angular momentum, the swing radius decreases and the swing angular velocity increases, thereby increasing the forward swing speed of the swing leg.

at the same time.

A smaller folding angle is also conducive to reducing air resistance and improving running efficiency.

Su Shen has long understood these technical things and is orderly in his work.

In addition to the experience of two lives, and the Sushen Speed ​​Laboratory, which has been investing heavily in this life—

In this way, Su Shen can make full use of this efficient technical movement during the curve running, so that the curve speed can naturally be faster.

Even curve running requires overcoming greater centrifugal force problems. Su Shen also optimizes the folding angle of the legs and controls the folding angle to better maintain body balance.

By the way, centrifugal force is converted into forward power, further improving the speed and stability of curve running.

Bolt also tilts his body inward moderately here.

In this way, the center of gravity of the body is moved toward the inside of the curve, thereby partially offsetting the effect of centrifugal force.

Body inclination angle is about 7°-8°.

This inclination allows the component force of gravity to form a certain balance with the centrifugal force, reducing the tendency of the body to throw outward.

Although Bolt didn't know these principles, he only knew that this was the training method and running mode that Mills told him, which was enough.

For him, it doesn't matter if he doesn't understand these things.

Mills he respects, just understand.

Guy increased the force of pushing the ground, especially the pushing the ground with his inner legs.

Through powerful ground-pushing forces, forward propulsion forces are generated to fight centrifugal forces.

When pushing the ground, you can make full use of the explosive power of the leg muscles to transmit the strength from the soles of your feet to the ground and push the body forward.

As he speeds up, he also needs to prepare for his "spiral ascension technique".

Su Shen should lift his legs high and swing forward quickly, and his thighs should be as close to his chest as possible, and his calves should naturally sag.

During the swing, Bolt pushed the knee of the swinging leg forward and upward to increase the amplitude and speed of the swing.

The landing position of Guy's legs should be as close to the projection point of the center of gravity of the body as close as possible to reduce braking and improve running efficiency.

Still significantly narrowed?

Frances was a little uneasy.

If it was a single event, he would definitely not care about how Bolt ran.

But this is not a single event.

This is a team match.

Team competition.

If Bolt runs poorly, it will definitely affect his disciple Powell, the fourth player.

"What happened? Why haven't you been up yet?"

In desperation, Francis even asked directly.

Mills just said a short sentence at this time-

"What's the hurry?"

Mills was actually a little upset now, but he knew that he had to be able to suppress the scene. He probably had a camera facing him now. He didn't want to leave any panic material behind.

Of course these are second.

The most important thing is...

The scene changes were unexpected.

Running on the way.

It's already a super fast one.

Why hasn't this gap narrowed significantly?

If this continues...

That's nothing to say.

He himself was also in a irritable mood.
To be continued...
