Chapter 58 Aerodynamics of Soccer Balls
"Children and gentlemen, it is a great honor to welcome you friends from China. We should have known each other for a long time. Let me introduce the man next to me." Linda introduced a man standing next to her with a smile on her face. .

"Jeff Rogers, the convener of our camp, Mr. Rogers is a senior football coach who has worked for Manchester United in the English Premier League for more than 15 years, focusing on youth training and technical work, and became our Nike partner Since we were partners, we have served as instructors in European and American youth training camps for many times, and are very popular among the students. Let us welcome Mr. Rogers to tell you about the specific arrangements for this youth training camp." Linda introduced it to everyone gracefully.

Lin Fei saw that Mr. Rogers was about 50 years old, and his temples were already gray, but under the two thick eyebrows, there was a burning gaze, but his body was a bit fat.

"Mr. Jin, children, you are very welcome to come to the American Youth Training Camp of the Chinese National Youth Team jointly organized by our Nike Company and Curry University. You can add me, Mr. Luo, I am an easy-going person." Mr. Rogers is very pleased We're getting closer to everyone soon.

"Fei, this Mr. Rogers said he is from Manchester United. Judging by his body shape, he doesn't look like a football player. He's very bloated!" Ye Tianyi whispered to Lin Fei from below.

"He's a coach, not a player. Not every coach has a monster figure like our coach Jin. You see, the head coach of the Spanish national team, Bosque, doesn't have such a big belly!" Lin Fei smiled.

"What you said is true. I really want to see how many brushes this Mr. Luo has!" Ye Tianyi rolled his eyes.

"Because we have limited time for this training camp, the arrangement is relatively tight. In the first two days, I will guide you to play football. Maybe on the third day, Miss Linda may have told you before that the world football superstar Luo Mr. Nardinho will be here to interact with everyone in person, and the end will be a game against the Curry University football team."

"Wow, I'm really looking forward to it!" Hao Shuai couldn't help blurting out from below.

"Children, at night, you can go to the muscle training room of our camp to do some indoor strength training. There are some world-leading professional training equipment we have introduced. It is the innermost room on our floor. I hope you can play happy."

Hearing the indoor training, the children suddenly became interested in playing and ran away excitedly.

"Mr. Rogers, I have caused you trouble." Jin Zhifei shook hands with Rogers politely.

"Coach Jin is too polite. In fact, Coach Jin's football skills are higher than mine. After all, he is the head coach of the Chinese National Youth Team." Rogers is very humble.

"Mr. Rogers is too flattering. Mr. has worked for Manchester United and other giants. He has a lot of work experience that I can learn from. I just want to take this opportunity to ask for advice." Jin Zhifei seriously asked for leave.

"Mr. Jin, you can't ask for advice, just communicate. You represent the national team. I'm just a coach of a non-governmental organization." Rogers has the usual humility of Westerners.

"What do you think is the main gap between Chinese players and European and South American players?" This question has been asked and answered by countless people, but it seems to be an eternal question. Fundamental improvement is bound to happen one day without the emergence of such problems.

"Mr. Jin, in fact, Chinese friends have asked me this question many times, and my answer has never changed. Let's not talk about adult players. In fact, there is not much difference between young players. The difference is probably a kind of passionate spirit." !” Rogers replied without thinking.

"Spirit? Isn't this word too broad? In fact, in China, spirit has been repeatedly emphasized! You know that China used to be poor and poor, and it is the spirit of striving to be the first to achieve today's achievements. Although many people It is said that Chinese football lacks spirit, but I personally do not agree!" Jin Zhifei is also a person who does not like to follow the crowd.

"Mr. Jin, you must have misunderstood the meaning of the spirit I said. The spirit I mean is pure sportsmanship, not the dedication you Chinese often talk about. The spirit of winning glory for the country is divorced from sports. The essence of the spirit, simply put, is that if one person plays football well, it is purely playing football, not for the collective, for the family, and not for the country, understand?"

What Rogers said caused Jin Zhifei to ponder. This was indeed a spiritual explanation he had never heard before. Thinking about it, it made some sense. If he was not playing pure football, but something other than football, how could he Cultivating world-class stars at the beginning, the current domestic atmosphere is too eager for quick success.

The first ray of sunlight in the morning passed over the English-style clock tower of the old library of Curry University, and sprinkled on the flat lawn football field.

Rubbing his sleepy eyes, Lin Fei saw that the lawn is not big, it should be slightly smaller than the national standard football field, but it is very neatly trimmed, and it can be seen that the maintenance personnel have put a lot of effort into it and are very dedicated.

Rogers changed into a white jersey and shorts today, looking particularly energetic. Although the old man's figure is a bit bloated, his body is straight.

"Children, I think that since you are members of the Chinese national youth team, you must have already undergone training in school and the national youth team, and you already have a certain understanding of football. Today I just want to share some of my experience. Share it with everyone." Rogers said to the children from China with a smile.

"Today I want to talk about the aerodynamics of dribbling. People play most of the time with running and dribbling. In addition to technical factors when dribbling, the aerodynamics of the ball as it travels is also very important."

"Aerodynamics? Are we learning football or flying airplanes?" Ye Tianyi said to Lin Fei suspiciously.

"Listen to Mr. Luo attentively. He has much more experience than us." Lin Fei glanced at Ye Tianyi and listened intently.

"There are many dynamic factors that affect the trajectory of the ball when dribbling and dribbling, but the key lies in the part and area of ​​contact between the foot and the ball. The area of ​​the inner side and the front of the instep contacting the ball is relatively larger than other parts. Therefore, when pushing the ball , It is easy to grasp the direction of the ball running. The part of the dribbling foot that touches the ball and the direction of the force are different, and the direction of the ball is also different. Use the side of the inner foot to touch the ball, and the ball runs sideways; use the front of the instep to touch the ball Back, the ball runs forward; use the side rear of the instep to touch the ball, the ball runs side to front; use the back or side rear of the outside of the instep to touch the ball, the ball runs forward or side to front. Generally, the straight dribble uses the front of the instep Or outside, curve dribble using the inside or outside of the instep."

While speaking, Rogers picked up a football and demonstrated it himself. "When the force of the dribble foot touches the ball does not pass through the center of the ball, the ball rotates. When the ball just leaves the foot and spins, the speed is very fast. But due to the principle of fluid mechanics, the air flow speed is fast along the upper edge of the ball, and the air flow speed is faster along the lower edge of the ball." The pressure is high, and ground friction needs to be overcome, so the ball speed slows down quickly. When dribbling, in order not to make the ball touch too far, often adopt the method of backspinning the ball. When the ball produces side spin, not only the ball speed is slowed down , and the ball changes from a straight line to an arc. When dribbling, the side spin method is often used to change the direction of the ball.

In the process of dribbling, the dynamic factors of the actions of dialing, pulling, buckling, and picking can suddenly change the direction of running, that is, change the position of the ball, so that although the opponent may touch the ball, it cannot be preceded by the dribble. The ballman touches the ball".

"Well, Mr. Luo's explanation is really detailed. Combined with the demonstration, I only had a feeling about the direction of dribbling before, but now I feel it is clearer." Lin Fei sighed.
