Can it work?

certainly.

Can do it.

Is this the fastest startup speed in Su Shen’s history?

If it is calculated, the reaction time is included.

That may not be the fastest.

But if...

You're just calculating, pure running time.

Then this shot.

Definitely the fastest.

None of them.

For example, his fastest 10-meter segment is the outdoor London race of 1.70.

If indoors, the fastest time is 1.75.

Such a situation.

In other words, Su Shen’s current pure startup speed should be 1.75 seconds under normal circumstances.

This shot is definitely impossible to have a super reaction.

Now everyone just thinks that Su Shen’s shot is fast.

But how fast is it?

Why is it so fast?

This is a question that should be understood.

Otherwise, you will only know one thing but not the other.

Only know the appearance, not the inside.

It's meaningless.

It's just a castle in the sky.

Then how did Su Shen do it?

Why did this shot start?

It would be so explosive.

Of course it doesn't mean that he used any magic.

It must be true.

That is also the magic of science.

To understand the principle, you must naturally understand the first point.

This is a plateau site.

The altitude exceeds 1300 meters.

The most significant environmental difference between plateau and plain areas is its lower air pressure and air density.

As the altitude increases, the atmospheric pressure gradually decreases and the air becomes thinner. The environmental characteristics of this thin air directly lead to a decrease in the oxygen content, and also changes in the air resistance.

According to the principle of air resistance.

During the sprinting process, athletes need to overcome a variety of resistances, among which air resistance is a part that cannot be ignored.

According to the principle of fluid mechanics, when an object moves in the air, the air will produce pressure and friction on the surface of the object, and its size is related to factors such as the speed, shape, and air density of the object.

According to the calculation formula of air resistance, we can know that

In plateau fields, due to the decrease in air density, when the athlete starts and accelerates, according to the formula, the air resistance experienced will be reduced accordingly at the same speed, drag coefficient and windward area.

Taking a plateau with an altitude of 2,000 meters as an example, its air density is about 80% of that of plains.

During the 100-meter start-up stage, the air resistance experienced by athletes during acceleration means that...the athletes can use their strength more effectively for the acceleration forward.

Instead of consuming it in overcoming air resistance.

This naturally enables the startup speed to be increased faster.

At the same time, you also need to consider the energy supply method of 100-meter sprint. 100-meter sprint is a typical anaerobic metabolic exercise. In a short period of time after the start, athletes mainly rely on the adenosine triphosphate-creatine phosphate system stored in the body for energy supply.

I believe everyone knows this.

So the question is, why can this system run faster under the plateau ground?

This is because this system can quickly release energy under anaerobic conditions-

Can power muscle contraction.

Since its energy supply depends mainly on the stored high-energy phosphate compounds in the body rather than the immediate oxygen uptake,...

During the startup stage, the relatively low oxygen content in the plateau area did not have a significant hindering effect on the athlete's energy supply system.

This is why the energy supply system of sprinters is more suitable for plateau sites.

But just an energy supply system is not enough to meet the plateau site.

There are also muscle outputs, especially short-range explosive outputs, such as long jump and high jump sprints.

In a plateau environment with low air resistance, the external resistance that athletes need to overcome for muscle contraction is reduced.

According to the muscle contraction force-velocity relationship described by Hill's equation, when external resistance decreases, the muscle can contract at a faster speed, thus generating a greater force output.

Therefore, when starting at 100 meters, this force can be converted more effectively into forward acceleration, allowing athletes to reach higher initial speeds faster.

Only by understanding these will you have the opportunity to start from a technical perspective.

Otherwise, if you just talk about technology, it would be nonsense.

Only by understanding these things can you start to combine the curved arm techniques - when the curved arm starts, the curved arm posture is more conducive to exerting the strength of the arm muscles.

The bending of the arms makes the biceps, triceps and other muscles at a more favorable contraction angle, and can swing faster and more powerfully at the moment of starting.

In addition, the bent arm movement can better cooperate with the leg pushing movement, form a coordinated force mode, transmitting force more effectively to the center of gravity of the body, and pushing the body forward to accelerate.

Of course, straight arms have this effect.

but……

In contrast, when the straight arm is started, the direction of force and efficiency of the muscles are relatively poor, making it difficult to achieve the best synergistic effect with the leg movements, and the acceleration effect at the start will be affected to a certain extent.

This is because in a plateau environment, the oxygen content is relatively low, and the energy supply of the human body will be limited to certain limits.

When the bent arm starts, the arms bent so that the biceps, triceps and other muscles are at a more suitable angle of contraction.

Under the mechanics of muscle contraction, at the optimal contraction angle, the muscles can generate strength with higher efficiency.

This is because the arrangement and contraction of muscle fibers can form a synergistic force more effectively at the appropriate joint angle.

Compared to straight arm starting, the curved arm posture can fully exert muscle strength under the limited energy supply and provide stronger power support for the start.

To put it bluntly, the utilization rate of energy is different.

Nowadays, we can only exert so much energy, but when the plateau oxygen content is relatively low, the human body's energy function caused by relatively lower oxygen content can be reduced to the limit.

After that, look at the slow motion of Su Shen going out.

Underground in the plateau field.

In fact, the other athletes have some errors in data accuracy when starting up and starting up the original plain.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! No matter how experienced you are.

How old-fashioned.

There will be no difference.

Why is this happening?

Of course not metaphysics.

Even if you have rich experience and thin air on the plateau, athletes will naturally need more precise and coordinated movements to save physical strength and improve efficiency.

It doesn't mean that you can be experienced.

As long as you still stand on the land of this plateau with your feet.

You will be affected by this buff.

You can think of it as a map of a certain game.

After walking in.

On this field, all your movement accuracy will undergo subtle deformation.

I don't feel that it's very good.
