Su Shen and Zhao Haohuan do not have any public testing levels in daily life.

You can tell by looking at the coaching staff...

It must be good.

Even quite good.

Yuan Guoqiang was always talking about "Su Shen" at night, and the rest didn't know what they said.

On the next day.

The 200 meters have begun.

After the warm-up, I smoothed my legs.

The test started.

Because there are not so many people running 200 meters.

So it will be done with one shot.

Everyone stood together.

Prepare for testing.

The total number of people who participated in the test was Liang Jiahong, Xie Zhengye, Zhou Bing, Su Shen, and four others.

Relative to 100 meters.

The number of people in 200 meters is indeed much smaller.

This also meets the standard of 200 meters in Asia and the world.

Because 200 meters are very painful.

It's enough for you to rush for 100 meters.

You can even grit your teeth and push it down.

But 200 meters are different.

400 meters requires a stronger sense of rhythm.

And if you want to rush 200 meters quickly, you have to set a good pace. It means that your phosphate system needs to explode, and your glycolysis system cannot be bad either.

This has stumped many people.

It is also why the entire 200-meter athlete pool is much smaller than the 100-meter athletes. It may even be worse than the 400-meter athletes.

It’s because I want to do both.

Quite painful.

You have to maintain the high speed.

It is more difficult than simply starting a high speed and maintaining a rhythmic speed.

This difficulty is a literal difficulty.

Very uncomfortable.

From the perspective of energy metabolism, during the 100-meter race, the energy supply of the phosphate system dominates. The ATP-CP stored by the human body can maintain high-intensity exercise for about 6-8 seconds under full-strength sprint.

For example, the current performance of excellent male 100-meter athletes is generally around 10 seconds. In this time range, most of the energy comes from the instant energy supply of the phosphate system. This energy supply method produces less metabolic waste, and the body will not produce too much fatigue substances in a short period of time.

From the perspective of physiological data, during the 100-meter sprint, the athlete's heart rate will rise rapidly, reaching 180-200 beats/minute, but due to the short exercise time, the heart rate will recover relatively quickly after the exercise.

At the same time, muscle contraction is mainly fast isometric contraction and centripetal contraction, and the activation of muscle fibers is mainly type II fast muscle fibers, which can generate greater strength and contract fast, helping athletes achieve rapid start and acceleration.

In the 200-meter race, the phosphate system played a major role in the first 6-8 seconds after the start, and then the glycolysis system began to supply a large amount of energy.

During glycolysis, each molecule of glucose decomposes to produce 2 molecules of lactic acid and 2 molecules of ATP.

As the lactic acid is produced in large quantities, the pH value in the muscles and blood will decrease, causing the muscle contraction ability to decrease.

Generally, within 3-5 minutes after exercise, the blood lactate concentration can reach 10-15mmol/L. This high concentration of lactic acid will cause muscle soreness, fatigue and decreased exercise ability.

Judging from physiological data, the heart rate of athletes in the second half of the 200-meter race will further increase, possibly even more than 200 beats/minute. Moreover, due to the accumulation of lactic acid, athletes' respiration rate will also accelerate, trying to relieve fatigue caused by anaerobic metabolism by increasing oxygen intake.

Muscle contraction not only causes rapid centripetal contraction, but also causes more centrifugal contraction due to fatigue, which increases the risk of muscle strain and also makes athletes feel stronger muscle aches.

If you understand these basic factors, you will know why Zhao Haohuan, Lao Yi, Xu Zhouzheng and others, whether it is a 100-meter player with a future 100-meter player or a 100-meter player with a future 200-meter player, is not good at it.

Because from the perspective of physiological data and energy metabolism, their physiological conditions, muscle conditions, and talent conditions do not meet the needs of 200 meters.

Not to mention endurance, most of these 100-meter players do not match talent attributes. In fact, most of the time, 100 meters and 200 meters are just sprinters, but in fact they are not the same type at all.

Although it is not as big as the difference between 100 meters and 400 meters.

But it is actually two movements.

It was just because there were not many players training in the 200m before, most of them were 100m in combination. After the 21st century, monsters like Bolt Blake basically ran 100m and 200m, which gave the 100m and 200m a fixed impression in the hearts of most spectators...

In fact, these two sports are really related, but they are indeed sports of two events.

Liang Jiahong ran because he needed to use 200 meters to enhance his later-range attributes. In essence, it was also for 100 meters.

Su Shen’s training mode that uses auxiliary phases to drive the main phase.

It has been promoted on Ersha Island for a long time.

Those who need it will do this type of training.

Liang Jiahong's talent is pretty good at 200 meters. In his last life, he was because of a cracked soles of his feet and he couldn't run more.

Training more.

Actually, his talent is pretty good.

Otherwise, he would not have been ranked among the top in China for several years. Judging from his normal 200-meter race, he has already achieved a very good result.

These are just some of the most basic parameters.

If technology is involved, there is still a corner. This 100-meter player may not be able to run well.

On the curve, the athlete's left foot lands on the outside and right foot on the inside. This landing method can increase friction and help the athlete turn better.

In this regard, Zhao Haohuan's talent is not good.

Of course there is no problem with the 150-meter straight path.

If it is a curve.

Then he is not easy to run at 150 meters.

Naturally, there is not much talent here when turning.

If he doesn't run 200 meters, he can only reach 150 meters just because of his extreme talent. He is not very outstanding in his talent on the curve.

At the same time, the posture of the head and body should be kept stable, and the eyes should look straight at the tangent direction of the curve to avoid affecting balance due to swaying vision.

This shows that the implementation of curve technology requires more vestibular organs to participate in balance regulation. The vestibular organs constantly send information on body position and movement status to the brain. The brain adjusts muscle contraction and relaxation based on this information to maintain the body's balance on curves.

You are like many people here, and you don’t have the talent in this area either.

So I chose it all.

There are really not many people who can match it.

Of course you have to say that you are strong enough.

Use strength to break skill.

That's OK.

But in fact, there are very few such people.

Even if you look at the West African descent who has been kissed by God, there are only a few people who want to give birth to such a person.

It would be nice to have 4 people here.

In addition, Su Shen and Xie Zhengye joined forces to refresh the altitude of 200 meters in Asia. It is becoming more and more difficult for ordinary people to add a step.

In the past, it might have been enough to run within 21 seconds.

Within 20 seconds, it is absolutely powerful.

It's easy to enter the national team.

What about now?

Even if you run out like this.

It doesn’t mean there is a future, and not many people will like you. Because now everyone is more concerned about players who can get close to 20 seconds.

Not to mention opening for 20 seconds.

Whether you can get close to 20 seconds is the key.

The appetite has been tricked.

The traditional market is increasingly compressed.

It's also because of this reason.
