A fast showdown.

People with extreme speed abilities also begin to show themselves.

For example, Alison Felix, the first female player in the 200-meter service, is in the extreme speed zone. His powerful explosive power and excellent speed endurance have become the key to winning, and behind it is complex and exquisite sports science principles.

From a muscle mechanics perspective, the explosive force produced by her leg muscles when contracting is extremely strong. During the extreme running stage, her quadriceps, gluteus maximus and calf triceps work together to reach x Newton's contraction force.

Let’s take a look at the scene after the rapid explosion.

The quadriceps are responsible for rapidly stretching the knee joints, providing the body with the initial motivation to move upward and forward.

The gluteus maximus further increases the thigh extension by forcefully stretching the hip joint and increases the propulsion force.

The triceps of the calf suddenly contract when they push the ground, bounce the body up quickly, and use the ground reaction force to push the body forward at a high speed.

This is entirely because she has the best speed-facing among all athletes.

In terms of speed and endurance, her body has an efficient energy metabolism system.

This allows her to quickly and continuously perform aerobic respiration during long-term high-speed exercises, providing a stable energy supply for muscle contraction.

Ordinary athletes cannot do this level.

It cannot be described as ordinary.

Most athletes.

99% of athletes in history.

Even higher probability.

Not even reaching her level.

Otherwise, why is the only king of the active women's 200 meters?

Not many brushes.

You can't get into the base.

At the same time, her body can effectively regulate the production and removal of lactic acid.

Although a certain amount of lactic acid will be produced when running at an extremely fast speed, her body has a strong lactic acid buffering ability. Buffer substances such as bicarbonate in the blood can neutralize lactic acid in time, maintain the relative stability of blood pH and delay the generation of fatigue.

Her lactic acid accumulation rate is controlled below mmol/L/min, which allows her to maintain high speed for a long time in the extreme speed zone without significantly reducing the speed due to fatigue.

This is the real talent.

Physiologically, it's better than you.

Unless you are born with such ability, you will look at your current training conditions and training level the day after tomorrow...

You can't get close to it at all.

Unless you have knowledge of the movement science towards systemics like Su Shen like the next few decades.

Otherwise, if you look at her, you will only stare at me.

That's all.

Feeling uncomfortable.

Why do you think the difference between people is so big?

In addition, her breathing rhythm is stable, providing her body with sufficient oxygen supply.

In the extreme speed zone, she adopts a breathing pattern that matches the pace frequency, completing a breathing cycle in each step.

The 200-meter athlete comes to run 100 in these aspects, and has a natural advantage.

In terms of body posture control, she always maintains a good posture.

Keep your shoulders horizontal to avoid energy loss caused by shoulder shaking.

The head is stable and the eyes are firmly looking straight ahead, providing a clear direction for the body to move forward.

It also helps maintain body balance.

When it comes to technology, Felix is ​​really unspeakable.

pity.

This is used to say that she does not mean that she retains it much faster. Instead, she borrows it to become a unit and see how the rest of the people do it and run.

In terms of body posture adjustment, Wei Yongli showed accurate control ability.

In the extreme speed zone, she will adjust the forward angle of her body and the thrust strength of her legs according to the speed and ground conditions.

When it is necessary to increase the speed, she will moderately increase the forward angle of her body and adjust the forward angle of her body to a proper one to enhance the pedaling force of her legs.

In this way, she is able to better utilize the components of gravity to push her body forward.

At the same time, she will also maintain her body balance through the contraction of her core muscles.

The strength of the core muscle group reaches x Newton, effectively preventing the body from losing balance due to excessive forward angle, ensuring that she can sprint forward steadily when running at high speed.

It can be seen that Wei Yongli is not idle either, and her progress this year is not small.

In addition, her legs are also very efficient.

In the extreme speed zone, her stride frequency and stride width are properly coordinated. Her leg muscles can quickly generate strength during the contraction and relaxation, and each time they push the ground, they can make full use of the ground reaction force to quickly push the body forward.

At this time, her leg movements were also in line with her arm swing. The arm swing could provide additional power for the body, thereby further improving her speed performance in the extreme speed zone.

Wei Yongli ran here very well, basically...

Not inferior to the famous Felix!

Wei Yongli didn't expect that Felix was so famous.

That's the world's top female flying man.

Even the people who want to challenge Joyna.

What level is her?

They are not on the same level as Felix.

That's right.

Can.

Things are sometimes dramatic.

Felix is ​​not in a perfect state every day. She is also a flesh-and-blood person, and she is also a flesh-and-blood body, just like this shot.

Her condition is completely inferior to last year.

Wei Yongli didn't say that she was easily pulled away by Felix, and...

She followed closely.

even.

There is also the possibility of overtaking at the extreme speed.

For a young player who has not yet become famous internationally. That is incredible.

Felix.

Felix was actually an Asian man except Chen Juan.

Hold it???

Even if this scene...

Some of them were unexpected by herself.

It doesn't matter.

Here comes.

You have to catch it.

The showdown with Felix was something Wei Yongli could not have imagined before.

I saw that the coordination between her arm swing and leg movements reached an extremely high level, and the angle of arm swing and leg pushing always maintained an accurate proportional relationship.

From the perspective of movement coordination, this precise coordination can complement and coordinate the forces of various parts of the body, avoiding the dispersion and waste of power.

At the same time, after long-term training and practice, the ratio of Wei Yongli's arm swing angle and leg pedal angle is accurately controlled by about 1:0.8. This precise coordination allows her to efficiently convert her body's energy into the driving force for progress in the extreme speed zone.

It made her speed faster.

Felix is ​​in normal condition now.

Instead, it has not mobilized so many.

It's really for Wei Yongli...

Bite it.

Wei Yongli felt a wall of speed.

but.
