Champion’s Heart

In fact, Kester doesn't have to worry too much about Zhou Yi, because Zhou Yi is not a complete stranger to the Dortmund youth team.

After all, Zhou Yi played against them before, and had two assists and one goal in that game, which left a very deep impression on Dortmund's youth team.

This is true whether it is Zhouyi's advantages or disadvantages.

This can be seen from the training content arranged by the youth team coach Ecker for Zhou Yi.

In addition to the whole training with the team every day, Zhou Yi has to do more physical training than other players, especially physical training.

What Zhou Yi lacks most now is physical fitness. His physical fitness cannot meet the requirements of a professional player at all.

Of course, Zhou Yi is not considered a professional player now, but becoming a professional player is the goal of hard work.

The youth team does not have a full-time physical coach, so Zhou Yi's physical training is in charge of the first-team physical coach Mr. Oliver Bartlett.

It can also be seen from this that Klopp's emphasis on Zhou Yi is indeed not just lip service.

You know, Oliver Bartlett is a physical training expert that Dortmund Club attaches great importance to. He is willing to start a small talk for a youth team player, which is not easy in itself.

In Zhou Yi's first physical training class, Bartlett did not immediately arrange a physical training plan for Zhou Yi, but folded his arms and asked Zhou Yi a question: How do you understand physical fitness, young man?

After listening to Kester's translation, Zhou Yi didn't understand why the coach asked this question, but he still answered honestly: It's endurance.

Wrong. After hearing the answer, Bartlet shook his head.

Wrong? Zhou Yi was surprised. He has always understood physical fitness in this way. Physical fitness is equal to endurance. Players with good physical fitness have good endurance. They can run longer and farther on the court. Is there anything wrong with this? of it?

And it's not just him who understands it this way, football games, FM and live football... all understand it this way.

How can this be wrong?

Seeing Zhou Yi's surprised expression, Bartlett asked him back: I heard from Tim that you have been insisting on going for a morning jog every morning?

Zhou Yi nodded proudly.

With his personality, it is indeed something to be proud of being able to persist for so long.

But Bartlett didn't see it that way.

He directly denied Zhou Yi's method of increasing physical fitness by jogging: Although jogging at a balanced pace on the ground and in the park can improve jogging ability, such training cannot improve your physical fitness in competitions. Physical fitness is not just simple. The concept of 'endurance'. Remember, football is a sport that involves many sprints and high-intensity anaerobic exercises, with some low-intensity aerobic recovery periods in between to prepare for the next high-intensity exercise bout.

Zhou Yi opened his mouth wide after listening to Kester's translation.

Seeing Zhou Yi's expression, Kester asked, What's wrong?

Uh... the coach said it very well, but... can he say it again?

Kester knew that Zhou Yi didn't understand, so he said to Bartlett: Can you explain in detail? Don't have so many technical terms...

To put it simply, you will sprint, shoot, jump, tackle or steal the ball during the game. These are high-intensity anaerobic movements. Your body needs to consume adenosine tritsubishilate, or ATP for short, to use Some of the glucose supplies the muscles to perform these high-intensity movements, explains Bartlett.

Although there are still many technical terms, Zhou Yi understood it this time, that is, what ATP and glucose the body needs to consume if it wants to do movements.

Then players will recover during the low-intensity phases of the game, such as walking, jogging, and standing, so that ATP will be replenished, and at the same time, the fatty acid will be eliminated. The fatty acid is what causes your body to lose weight in the big game. The reason why you feel sore after a lot of exercise. Niacin is metabolized by aerobic metabolism, which is one of the reasons why people breathe harder after slowing down or stopping strenuous exercise.”

Bartlett continued to explain. He explained with practical examples. Even though his mouth was still full of professional terms, Zhou Yi could understand it.

To put it simply, rest is needed after strenuous exercise so that the body can recover and gain energy to continue strenuous exercise.

The time interval between a player's return to high-intensity exercise depends on the rate of his ATP replenishment, the amount of fatty acids that are metabolized, and the completion of some other electrolytic processes related to muscle contraction. Recovery is an aerobic process. The higher a player's aerobic capacity, the faster he recovers and the more often he can run at full speed. Consequently, the longer he can play at his best without fatigue.

So, the physical fitness we talk about in football is not just your ability to run for a long time, but your ability to recover quickly. Football is not a marathon. You don't need to run non-stop for 90 minutes. Instead There will be a lot of frequent anaerobic exercise. If your body cannot recover from anaerobic exercise quickly, then naturally you will not be able to last long in the game, and you will easily feel tired.

Once you understand what physical fitness is in football, you'll understand why I said jogging in the park doesn't improve your physical fitness in games. Because improving your jogging ability doesn't make you in the game. Recover energy quickly during the game.

Zhou Yi was dumbfounded, but this time it wasn't because he didn't understand, but because he was shocked by the professionalism of professional football clubs.

Yes, after hearing Bartlett's words now, his mind is full of two words: professional!

This is a professional!

I used to think that running 10,000 meters with sandbags would be enough for my physical fitness, but now I realize that is nonsense.

And not only him, judging from the slogan of 10,000 meters a day in Haigeng's spring training before, Chinese football is not very professional...

No wonder the level of Chinese football is not improving.

If the Chinese football practitioners are so unprofessional, they still think about going out of Asia and going to the world... that is indeed a dream.

The Chinese team has participated in the World Cup finals once in history, but that time was just luck, and it does not mean that the strength of Chinese football has improved. Everyone has seen what happened later, which fully shows that Chinese football has not yet found the right direction. .

Then Zhou Yi further saw the professionalism of European clubs.

After Bartlett explained to Zhou Yi what the concept of physical fitness in football is, he did not immediately start training Zhou Yi, but conducted a test on Zhou Yi. According to him, this is to detect the distribution ratio of fiber types in Zhouyi's muscles.

Based on the previous explanation of fitness, it can be seen that football players cycle between anaerobic and aerobic exercise during the game. In the human body, there are two kinds of muscle fibers corresponding to these two kinds of movements.

Large fast-twitch fibers can generate large amounts of tension very quickly, but cannot sustain that amount of tension over multiple contractions. Smaller, slow-twitch fibers generate less tension at a slower rate, but can sustain repeated contractions.

Therefore, fast-twitch fibers can generate a large amount of anaerobic energy for the rapid generation of tension. When players sprint, jump, tackle, and shoot, they need explosive power, and what works in the body is anaerobic energy. Slow-twitch fibers, on the other hand, can generate large amounts of aerobic energy for repeated contractions.

The distribution of fast-twitch and slow-twitch fibers is largely determined by genetics, which is called talent.

Some people are born to run fast, which means that there is a higher proportion of fast muscle fibers in the body.

It is impossible to change the distribution ratio of muscle fibers through acquisition, so we must first figure out which muscle fibers are more in Zhou Yi, so that we can make targeted training arrangements.

It's not what everyone thinks, Zhou Yi's physical fitness is not good, so he will directly focus on the training content to enhance his physical fitness.

How to test Zhouyi's muscle fiber distribution?

In fact, it is also very simple, just test the muscle endurance. First of all, use the equipment to test the maximum strength of Zhouyi’s muscle contraction. For example, if you want to test the proportion of muscle fibers in a part of the leg muscles, let Zhouyi sit on the adjustable leg kicking exerciser, and then let him push hard on the front baffle, and then gradually increase the weight , Observing Zhou Yi's situation, if Zhou Yi really can't push a certain weight, then the last weight he can push is the maximum force of his muscle contraction.

Then take 80% of this maximum strength as the strength standard for testing. Let Zhou Yi repeat training on this strength to see how many times he can persist.

If it is more than fifteen times, it means that this part of the muscle has a high proportion of slow-twitch fibers. If it's less than five reps, it means a high proportion of fast-twitch fibers.

Just such a part of the muscle test.

Finally Bartlett came to a conclusion.

The ratio of Zhouyi's fast-twitch fibers to slow-twitch fibers is 54:46.

He has fewer slow-twitch fibers, so he has less energy.

This result made Zhou Yi a little disappointed: Doesn't that mean that I am born with poor physical fitness, and it is useless to improve my physical fitness?

Bartlett shook his head: If this is the case, what do we need our physical fitness coaches to do? Our physical fitness coaches are specially responsible for cultivating and enhancing your physical fitness. You must know, young man. Speed ​​is born, but physical fitness can be improved through acquired training. of.

He patted Zhou Yi on the shoulder: So don't worry, you won't be able to play only half a game forever.

Zhou Yi quickly defended, It's seventy minutes.

But Bartlett didn't care about the difference.

Almost. He shrugged. Okay, that's the end of today.

Zhou Yi was surprised: No more training?

I'll start training after I go back to formulate a targeted training plan for you. Bartlett said. We will start formal training tomorrow. Take a good rest today. Don't be too tired. You will start training when you fly over from China. There is no benefit in doing this except to show your own attitude. Remember, rest It is the first step of physical training, if you don’t rest well, you don’t want to train well.”

Bartlett picked up the book that recorded all the muscle data of Zhou Yi and left. Zhou Yi was still in a daze, pondering over his last words.

Rest is the first step in physical training…

This is the first time he has heard of it.

But...seems to make sense!

Professional!

Mr. Bartlett has such an attitude. He speaks very straightforwardly. He doesn't like nonsense. So don't take it to heart, Zhou Yi. Kester thought that Zhou Yi was stunned because he was stimulated by Bartlett's words, and quickly comforted him.

Zhou Yi shook his head: How could it be, Mr. Kistor. There is such a coach who directly pointed out my problems, saving all of us time, I am too happy. Don't worry, Mr. Kistor. I am not a glass heart!

That's good. Keist laughed. Okay, let's leave too. Did you forget that you are moving today?

Zhou Yi was stunned for a moment before he remembered that there was such a thing!

The club has approved his application to stay at Wagner's house, and he will move from the hotel to his teammate Mark Wagner's house today!
