Chapter 6 Physical Test Report

Time goes back to yesterday afternoon.

Klopp is in his office, reviewing the results of the team physical test report he just received.

Next to him, all the members of the fitness coaching staff are there. After reading a report by one person, Klopp will pass it on to the fitness coaches.

He's staring at a man's report right now.

"Oliver," he said.

Oliver Bartlett leaned over.

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

"Zhouyi's?" Bartlett asked.

"Um."

Bartlett picked up the report and looked at it seriously.

After reading this page, scroll down.

After flipping through, he took the report and said to Klopp: "I remember when he just entered the youth team, we gave him a similar physical test... The report is still with me, waiting for me to get it."

After speaking, he went straight out of Klopp's office, and the other colleagues all looked up at Bartlett's back in a hurry, a little strange.

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

Not long after, Bartlett returned to Klopp's office with a report.

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

Heart rate is an important indicator for athletes, especially when it comes to fitness.

There is a relatively simple comparison method, that is, professional athletes, especially endurance athletes, have a lower heart rate than ordinary people. This is the result of the adaptive adjustment of the body and heart after athletes have undergone professional training.

Therefore, 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 point has also been verified by Zhou Yi.

When he first came to Dortmund,

I did a physical examination once, which was the physical examination for joining the team.

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

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

But it's actually far more complicated than he imagined.

The team doctor asked about his medical history. Whether you have had any surgery before, and your family medical history should also answer truthfully. Because Zhou Yi has not played for other clubs before, Dortmund cannot ask Zhou Yi's previous clubs about his injury history, this can only be done consciously by Zhou Yi. If Zhou Yi wanted to hide something, it would be difficult for Dortmund to know.

But Zhou Yi has nothing but a cold. There is no history of injury, and no surgery has been done.

Then Zhou Yi was asked about his living habits, such as what time he went to bed every day. What time do you wake up and how is your sleep quality? Whether it is good or not, is it a dream? There are not many dreams. Whether you have insomnia and other conditions, drink coffee or not. Does drinking coffee have any effect on sleep, how often do you drink coffee, and your usual eating habits. The taste is light and heavy...

Afterwards, a heart examination was also done, including an electrocardiogram test, a heart echo test, etc.

A urine test will also be done to check for protein and ketones to avoid problems such as diabetes.

This is followed by a muscle and joint examination, where the physiotherapist assesses the range of motion of each joint and compares it to normal values.

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

A blood draw is also essential. Smoke once before the physical examination and again after the physical examination.

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

The ability of aerobic exercise and anaerobic exercise is a very important indicator of football players, and there will naturally be no shortage of tests in this area. Zhou Yi was asked to test his limits as much as possible in this kind of test.

At that time, Zhou Yi was wearing an oxygen mask similar to that of a pilot, and his body was covered with electrodes. He was running on a treadmill with a very high intensity, and his stride frequency and the angle of the runway of the treadmill were constantly changing.

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

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

Zhou Yi hadn't thought of these things before, but he had experienced them all during the physical examination.

But what Bartlett wants to compare now is the results of Zhou Yi's physical examination when he first joined the team and the results of his current physical examination.

In just eight months, Zhou Yi's heart rate has changed significantly. Whether he is exercising or resting, his heart rate is slower than before.

And this is an important indicator of physical fitness.

To put it simply, when the human body is doing strenuous exercise, the metabolic rate will increase sharply, and the heart will have to use its reserve power to meet the increased demand of the body's metabolic rate by increasing the cardiac output per minute. The so-called cardiac output per minute is the volume of blood ejected by one ventricle contraction and expansion of one side of the heart.

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

The work done by each stroke of a car engine piston is similar to the stroke volume of a human being.

The higher the power of the engine, the greater the power, the greater the heart rate, the greater the output energy, and the better the exercise ability.

During exercise, cardiac output per minute increases four to six times or more compared to a resting state of inactivity.

Generally speaking, when ordinary people do strenuous exercise, they increase their cardiac output by increasing their heart rate, which is why ordinary people feel their heart beat fast during strenuous exercise. Because the heart does not speed up the contraction and expansion, there is no way to increase the oxygen supply.

Normally, the bleeding volume of the heart during each pacing is about 70 to 80 milliliters. When the stroke volume increases several times during exercise, the heart will bear a huge load. Therefore, ordinary people without professional training cannot maintain this kind of high-load exercise for a long time, which may easily lead to unexpected situations such as cardiac arrest, and in severe cases, sudden death.

But the heart can be changed through training.

Long-term high-load endurance training will enlarge the heart chamber and thicken the ventricular wall, and the heart rate will also decrease.

Players are always in a state of sympathetic nerve excitement during training and competition - the activity of the sympathetic nerve mainly ensures the physiological needs of the human body in a tense state - at the same time, the reflex causes the vagus nerve tension to continue to increase - the vagus nerve controls the heart and other organs. glandular secretion.

The benefit of slowing the heart rate for exercise is that it can reduce the oxygen consumption of the myocardium. After all, cardiac pacing also requires oxygen to supply energy. If the heart beats too fast, it uses up more energy and oxygen, leaving less energy available to the rest of the body. That's why you want your heart rate to slow down.

Heart rate slows down. Myocardial oxygen consumption is reduced. At the same time, it prolongs the diastolic period, increases the diastolic coronary perfusion time, and increases the oxygen supply to the myocardium.

According to statistics, the heart rate of professional players is generally lower than that of ordinary people. Their heart rate at rest or sleeping is forty beats per minute, which is not unusual.

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

The change in Zhou Yi's heart rate shows that his athletic ability has increased. Or specifically increased stamina. Because the slowing of the heart rate is basically related to endurance exercise.

This is actually very normal. Anyone who undergoes systematic and scientific training can lower their heart rate. This is a manifestation of the human body's self-regulation.

However, some people are better at self-regulation and adaptability, while others are worse.

Now Zhou Yi's two medical reports are in front of Klopp and Bartlett. They found that Zhou Yi had made great progress in physical fitness.

You know, eight months ago, Zhou Yi was still an amateur rookie who had never received professional systematic physical training. Eight months later, his physical condition has greatly improved. This improvement surpassed Zhou Yi's muscle strength - there were also muscle strength tests in the two physical examinations. In this regard, the progress of Zhouyi is relatively small.

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

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

Because in Zhouyi's future in his mind, all abilities are based on abundant physical fitness.

Whether it is Zhou Yi's playing style. Or Dortmund, which Klopp himself coaches, requires a lot of physical support.

If Zhou Yi is a player whose physical fitness increases slowly no matter how he trains, and is not good at physical fitness, then Klopp's evaluation of Zhou Yi will be lowered, and his decision to buy him may have been wrong.

Although the club will not have much loss, not every young player can eventually become a talent. But after seeing Zhou Yi's talent, Klopp will regret it if he fails to become a talent in the end. Because Zhou Yi's talent is not something that any talented player can have...

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

"His strength training should be based on the average standard of the whole team, and there is no need to increase it." Klopp began to say to the entire physical fitness coaching staff. In fact, he mainly said to Wang Le, who was in charge of strength training.

Wang Le nodded: "Okay. Anyway, no matter how hard the kid trains, he can't become a bodybuilder like me. His muscle type is different. Maybe that kid is a marathon runner."

Generally speaking, long-distance runners and marathon runners seldom see strong muscle maniacs. They are often thin, with slender hands and feet, and don't look like much muscle, but they often have very good endurance. Especially the long-distance runners in Kenya, who look like they are malnourished, can dominate the long-distance running. It's certainly not because Kenyans are generally nutrient deficient...

"But for his physical training, we can ask for more." 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 training volume than ordinary athletes. Because their recovery period is shorter than that of ordinary athletes.

Subsequently, in the discussion between Klopp and the physical fitness coaching staff, Zhou Yi's personal physical fitness training plan was released. (To be continued.) Enable new URL
