Looking at Zheng Yi's surprised look, Sassi's smile fell on his face again and said, "Relax, I know that it is not easy to push back and start over with the concept that I have accepted, but I still hope you can accept it again, okay?"

Zheng Yi nodded mutely. Now he has returned to a white piece of paper, just like he has just entered Hengyuan, searching up and down.

"Very good!" Sassi praised, and said: "People usually think that physical fitness or physical fitness can be improved through exercise or long-distance running. First of all, this concept has no problem and is correct, but it is not comprehensive. Especially in improving physical fitness, running is not of great significance to improving physical fitness. The reason is very simple. Football is not a marathon, and endurance is not the only assessment standard. It includes a series of low-intensity aerobic recovery exercises and anaerobic high-intensity consumption exercises. The so-called physical fitness is actually the balance between the two..."

The storm of Sassi was heard, but Zheng Yi was confused, and his whole face felt as uncomfortable as if he had constipation. He was confused.

Fortunately, Sassi is Spanish and speaks English. If he speaks Italian, it is no different from listening to the heavenly books. However, Sassi is not much better in speaking English. There are too many professional words, so Zheng Yi's vocabulary is not enough.

So when Zheng Yi heard it, he looked at Sassi asking for help.

"Don't understand?" Sassie asked.

"Yeah, yeah!" Zheng Yi nodded violently, not embarrassed.

Sassie frowned slightly, pinched her chin with one hand and thought: "Sorry, I should actually consider this and wait for me."

Sassie showed a very gentlemanly smile, then turned and left. After about a minute, Sassie returned to the scene with a glass bowl and a sponge.

"Let's make an interesting game." Sassie put the bowl and sponge in front of Zheng Yi, but Zheng Yi didn't understand what Sassie was going to do.

"This is a sponge full of water. You can think of it as an athlete with abundant physical energy. I will squeeze out the water in the sponge later, and this process can be regarded as a process of physical energy consumption, just like this." As Sassie said, he pressed out the water in the sponge. After flattening the sponge, his hand did not take it away. Instead, he looked at Zheng Yi and continued: "Human physique, tissue, and structure are very close. Things like genetic mutations only exist in science fiction films, so no matter which player will have the sponge in my hand, and the physical energy is squeezed dry. But the question is, why can some players run for 90 minutes or even longer, while some players cramp in 70 minutes or even shorter, such as you."

Yes! Why?

Zheng Yi wanted to know too, so he shook his head at Sassi.

Sassi didn't expect Zheng Yi to say it. If he could say it, he would have lost his energy.

"Because of that!"

After saying that, Sassie took the hand pressed on the sponge away, and immediately the sponge slowly rose and sucked a lot of water around it back.

After more than ten seconds, the sponge returned to its original water content height of one-third.

Zheng Yi, who witnessed the whole process, understood something, but it was still vague.

Sassie continued: "I mentioned to you before that physical fitness is the relationship between balanced consumption and recovery. Football is not a marathon, and you don't have to be in high-intensity anaerobic consumption all the time. If this is the case, the time of football matches needs to be reduced by at least one third. Players who know how to play will use slow and low-intensity periods to buffer physically, just like I took my hand away from the sponge."

"In many people's understanding, good physical fitness means running the longer the better. This understanding is very one-sided. Only Superman can do it for 90 minutes of sprinting, but ordinary humans cannot. Therefore, the real standard for judging a football player's physical fitness is not how long he can run, but his short-term recovery ability."

"The stronger the recovery ability, the stronger his ability to continue running, thus creating the [Three-Lung Iron Man] we are in our mouths or in our impressions."

"And your morning exercises and running only enhance your physical fitness and endurance limits, which does not help your physical fitness much. When you encounter high-intensity consumption, you should be bored or bored, just like the training just now."

"What I have to do now is improve your ability to recover in a short period of time when it is severely consumed."

After Sassi finished speaking, Zheng Yi was completely stunned. Of course, this stupidity was not a fool who was confused and confused, but a fool who was enlightened and suddenly realized.

The "physical fitness" I talk about every day turns out to be like this. It's not what Lao Chen said. You can do it by running and training. No wonder I practice every day, but my physical fitness is not rising. It turns out that I haven't practiced to the point...

It’s not to blame Chen Jingang, the older generation of Chinese footballers has this idea, and they believe that running is the best way to improve players’ physical fitness.

When I first introduced the 12-minute running and physical fitness test, many old footballers were quite sneering, but they didn't try it too well.

However, just after the introduction of twelve minutes of running, Chinese footballers were fascinated by running and regarded it as a good medicine to solve all problems.

So now many people are scolding Chinese players, how can they be like this? Looking at others and looking at you, I can’t bear to look at them directly.

In fact, it seems that it is unfair to accuse the players of unilaterally. People practice this way when they are young, but no one told them: The young man doesn’t practice this way, it should be like this.

The backwardness of Chinese football is not only reflected in the results that can be seen by the naked eye, but also invisible concepts. In terms of professionalism, in terms of physical training, it is already much behind Europe, let alone other things...

...

After figuring out the new concept of physical fitness, Sassi continued to explain to Zheng Yi in an easy-to-understand manner how to improve physical recovery ability.

During this period, Sassi was holding Zheng Yi's physical examination report, with detailed data from Zheng Yi. Overall, Zheng Yi is pretty good because the proportion of slow muscle fibers that determine physical fitness is balanced. It can provide faster recovery for the consumption brought by fast muscle fibers. The task now is to further stimulate Zheng Yi's slow muscle fibers and increase the proportion of muscle fibers.

The relevant training plans and contents were also prepared in advance based on Zheng Yi's physical examination report.

Looking at the training programs, Zheng Yi once again realized what a professional is, because in the plan prepared by Sassi, there are not only projects, but also why we need to exercise this place and the goals we need to achieve. It can be said that it is "special medicine for treatment", rather than a general way to use the equipment directly if we are not physically compatible.

After all this, Zheng Yi's first physical training class in Milan officially began.

In this class, Zheng Yi fully enjoyed the enhanced version of physical training, which was very cool and amazing...

...

What is muscle fiber? It is very detailed on Baidu. Another 109 chapters have been modified, which is much smoother than the first time.
Chapter completed!
