Champion’s Heart

Time went back to yesterday afternoon.

In his office, Klopp was reviewing the results of the team physical examination report he had just received.

Beside him, all the members of the fitness coaching staff are present, and Klopp will pass it on to the fitness coaches after reading one's report.

He is staring at a man's report now.

"Oliver," he said.

Oliver Bartlett leaned in.

"Look at this." Klopp pointed the chart on the report to Bartlett. That's a graph showing the player's heart rate changes at different speeds.

"Yi Zhou's?" Bartlett asked.

"Ok."

Bartlett picked up the report and took it very seriously.

After reading this page, I turned down.

After turning over, he told Klopp with the report: "I remember when he just entered the youth team, we did a similar physical examination for him...the report is still there for me, waiting for me to get it."

After talking about it, he went directly out of Klopp’s office, and all the other colleagues looked up at Bartlett’s hurrying back, which was strange.

Klopp did not explain, but continued to read the next report.

It didn't take long for Bartlett to return to Klopp's office with a report.

Then he turned the two reports to the same chart page and compared them, then knocked on the report: "Well, the heart rate has changed significantly. His heart rate has dropped."

Heart rate is an important indicator for athletes, especially in terms of physical fitness.

There is a relatively simple comparison method, that is, professional athletes, especially athletes in endurance, the heart rate will be lower than that of ordinary people. This is because after the athletes have undergone professional training, the body heart is adaptively adjusted.

So by checking a person's heart rate changes during exercise, it is easy to see whether he is a qualified athlete or whether he has received professional training.

This has also been verified by Zhou Yi.

When he first came to Dortmund, he had a medical check-up, which was a team check-up.

In fact, during the physical examination. Zhou Yi has already felt the professionalism of European football clubs.

He used to think that physical examination was a simple test of height, weight, endurance and speed.

But in fact it is far more complicated than he thought.

The team doctor asked about his medical history. Whether there has been any operation before, the family medical history should be answered truthfully. Because Zhou Yi had not played for other clubs before, Dortmund could not inquire about his injury history from Zhou Yi's previous clubs. In this regard, Zhou Yi could only rely on himself. If Zhou Yi wants to hide something, Dortmund is also difficult to know.

But Zhou Yi except for colds. There is no history of injuries, and the operation has never been done.

After that, Zhou Yi's life habits were all questioned, such as what time does it go to bed every day. What time do you get up and how good is your sleep. Is it good or bad, dreaming, not much dreaming. Whether there is insomnia and other conditions, drink coffee. Does drinking coffee have any effect on sleep, how often does coffee drink, and usual eating habits. The taste is heavy...

Afterwards, he also had a cardiac examination, including electrocardiogram test, cardiac echo detection, etc.

A urine test will also be conducted to check the condition of protein and ketones to avoid problems such as diabetes.

This is followed by muscle and joint examinations. The physical therapist will assess the range of motion of each joint and compare it with the normal value.

Muscle strength is also very important. For example, there is a certain imbalance in the muscles of the legs, which may affect the player's ability to run long distances.

Blood drawing is also essential. Draw once before the medical examination and again after the medical examination.

From the blood test results, you can see the player's kidney function, vitamin intake, and changes in these indicators during exercise.

The ability of aerobic exercise and the ability of anaerobic exercise are very important indicators for football players, and naturally there will be no shortage of tests in this regard. Zhou Yi was asked to test his limits as much as possible in this test.

At that time, Zhou Yi was wearing an oxygen mask similar to a pilot. His body was covered with electrodes, and he ran a very strong run on the treadmill. The cadence and the angle of the treadmill continuously changed continuously.

This kind of running can analyze Zhou Yi's aerobic metabolism ability, which is the ability to use oxygen during exercise.

In addition to these physical examinations, there are dental examinations and intelligence tests.

These things were never thought of by Zhou Yi before, but they were all experienced in the physical examination.

Now what Bartlett wants to compare is the result of Zhou Yi's medical examination when he first joined the team and the result of the current medical examination.

In just eight months, Zhou Yi's heart rate has changed significantly. Whether during exercise or at rest, his heart rate has become slower than before.

And this is an important indicator of physical fitness.

To put it simply, when the human body performs vigorous exercise, the metabolic rate will increase sharply, and the heart will have to use reserve power to increase the body's metabolic rate by increasing the stroke volume per minute. The so-called stroke volume per minute is the volume of blood ejected once when the ventricle on one side of the heart contracts and swells.

The blood is responsible for supplying oxygen to the organs and tissues of the whole body, so the heart stroke volume per minute can also be understood as the output energy of a person's heartbeat every time.

The work done by the engine piston of a car every time it is inserted is similar to the human stroke volume per minute.

The higher the power of the engine, the more power, and the more the heart's stroke volume, the greater the output energy, so the better the athletic ability.

During exercise, cardiac output per minute will increase four to six times or more compared to the quiet state when not exercising.

In general, ordinary people increase their cardiac output by speeding up their heart rate during vigorous exercise, which is why ordinary people feel their heartbeat beating quickly during vigorous exercise. Because the heart does not accelerate contraction and expansion, there is no way to increase oxygen supply.

Normally, the bleeding volume of the heart during each pacing is about 70 to 80 milliliters. After the exercise volume is increased several times during exercise, the heart will bear a huge load. Therefore, ordinary people without professional training can not maintain this high-load exercise for a long time, which can easily lead to sudden cardiac arrest and other unexpected situations. In severe cases, sudden death will occur.

But the heart can be changed by training.

With long-term high-load endurance training, the heart's heart cavity expands and the ventricular wall thickens, and the heart rate also decreases.

Players have been in a state of sympathetic excitement during training and competition-sympathetic nerve activity mainly guarantees the physiological needs of the human body during stress-and at the same time, reflexivity causes the continuous increase of vagal tone-the vagus nerve innervates the sensation, movement of the heart and other organs, and Secretion of glands.

The benefit of slowing heart rate for exercise is that it can reduce the oxygen consumption of the myocardium. After all, heart pacing also requires oxygen to supply energy. If the heartbeat is too fast, it will consume more energy and oxygen, so that less energy is supplied to other parts of the body. This is why the heart rate is slowed down.

Heart rate slows down. Myocardial oxygen consumption is reduced. At the same time, the diastolic period is extended, the perfusion time of the diastolic coronary artery is increased, and the oxygen supply of the myocardium is increased.

According to statistics, the heart rate of professional players is generally lower than that of ordinary people. Their heart rate during quiet or sleep is forty times per minute, this is not a special phenomenon.

So from the heart rate you can see the level of sports of a player.

Zhou Yi's heart rate changes indicate that his athletic ability has increased. Or specifically, increased endurance. Because the slower heart rate is basically related to endurance exercise.

This is actually quite normal. Anyone who has been systematically trained can reduce their heart rate. This is a manifestation of human self-regulation.

However, some people have strong self-regulation and adaptability, while others are poor.

Zhou Yi's two medical reports are now in front of Klopp and Bartlett. They found that Zhou Yi's progress in physical fitness was quite large.

You know, Zhou Yi was an amateur rookie who had never received professional system physical training eight months ago. After eight months, his physical condition has greatly improved. This improvement is greater than Zhou Yi's muscle strength-there are also muscle strength checks in two physical examinations. Zhou Yi's progress in this respect is relatively small.

This shows that Zhou Yi is a person with great potential in physical fitness.

This is a good thing for Klopp and makes him more optimistic about Zhou Yi's future.

Because of Zhou Yi's future in his mind, all abilities are based on abundant physical energy.

Whether it is Zhou Yi's playing style. Dortmund, who Klopp himself coached, all required a lot of physical support.

If Zhou Yi is a player who does not increase his physical fitness regardless of his training, Klopp's evaluation of Zhou Yi will be lowered, and the decision to buy him himself may be wrong.

Although the club will not suffer much, not every young player will eventually become a talent. But after seeing Zhou Yi's talent, Klopp would be very sorry if he didn't succeed. Because talent like Zhou Yi is not something that any talented player can have...

There are tens of millions of midfield players in the world, and there are not few world-class midfield organizers, but only Harvey himself can play like Harvey.

"His strength training is based on the average standard of the whole team, no additional increase is needed." Klopp began to say to the entire fitness coaching team~www.readwn.com~ Actually mainly to Wang Le who is responsible for strength training of.

Wanler nodded: "Okay. Anyway, no matter how much training the kid can become a bodybuilder like me, he has different muscle types, maybe the kid is a marathon runner."

Generally speaking, long-distance runners and marathon runners rarely see strong muscle madness. They are often thin, with slender and dry hands and muscles. They don’t have much muscles, but they often have very good endurance. Especially the long-distance runners in Kenya, one by one looks like malnutrition, but can dominate the long-distance running. This is certainly not because Kenyans are generally lacking in nutrition...

"But for his physical training, we can have more requirements." Klopp turned to Bartlett.

"No problem. In terms of physical fitness, I think Zhou Yi is a talented player." Bartlett said.

Talented athletes can maintain a higher training intensity and complete a larger amount of training than ordinary athletes. Because their recovery period is shorter than ordinary athletes.

Later, in the discussion between Klopp and the fitness coaching team, Zhou Yi's personal fitness training plan was just released. (To be continued.) Activate new URL
