    Arnhem returned to the Amsterdam train, and the players of the AFC Ajax Youth Youth Team were laughing, and a massacre made them very excited and unscrupulously teased the final performance of the Vitesse Youth Youth Team. ∈♀

    Qin Xiong sat by the window and looked at the scene of the rapid retreat outside the train. There was not much excitement.

    His ambitions, outsiders can not understand, perhaps many people think that 18-year-old, step by step in the Youth Youth Team, is a normal development track.

    However, he just wants to step into the sky!

    In particular, the Youth Youth Team is completely unfeeling.

    Perhaps, switching to the Vitesse Youth Team to play against the AFC Ajax Youth Youth Team may be a little more challenging.

    Through this game, the teammate on the field has already recognized him, Vertonghen sat next to him, Bukhari and Babel sat opposite him, and the three people would actively chat with Qin Xiong from time to time to talk about interesting things in the game, such as a moment in the opponent. The wolf does not look like a stunned or painful expression after losing the ball again.

    As a winner, taking the loser as a talk for fun, may not be moral, but it is true in every corner of the world.

    It can be said that there are no losers, and there are winners?

    The winner is to set off his own success with the pain of the loser.

    Qin Xiong is not interested in talking about these. Teammates don't mind, only when Qin Xiong is an introverted person. On the court and off the court, Qin Xiong is the opposite of the two people. On the court, he is very active and ubiquitous. Under the court, he will stay in the corner quietly. If he does not take the initiative to disturb, it seems that he does not exist.

    Most of the teammate accepted him and recognized him from the bottom of his heart. After all, everyone gathered in AFC Ajax, playing football as a bridge, and football strength is the foundation of this collective existence.

    However, some people were dissatisfied with Qin Xiong, and Mopus and Yilmaz sat on the cold bench for 90 minutes. They witnessed the performance of Qin Xiong's rulers on the court. Qin Xiong scored every goal like a bang. In their hearts, their sense of crisis has increased dramatically!

    Back in Amsterdam, Qin Xiong bid farewell to teammate and returned to Woodrow Street's apartment alone.

    In front of the apartment, Freddy sat outside De Koize's restaurant and waited for Qin Xiong. When Qin Xiong came back, he immediately opened the chair next to him and waved to the waiter in the restaurant to go to dinner. Then he asked Qin Xiong today. How is the game.

    Qin Xiong told Freddy the result in an understatement.

    "Ha ha ha, good, has Boulinder praised you? Have you said that you will be promoted to a high-level echelon? ”

    Qin Xiong shook his head and waited for the waiter to come up for dinner and dine quietly.

    After dinner, Qin Xiong returned to the apartment, took a break and started self-study at night.

……

    On the following day, Qin Xiong went to training as usual. Because there was a match yesterday, today's training tasks are not heavy. It is mainly for recovery and relaxation. The afternoon training is over, because the Reserve Team is going to play, later, First. Team will also greet Eredivisie at home, and the Club is more focused and naturally placed on the First Team.

    The teammates have left, some are going to see the Reserve Team competition. If you are in good economic condition, you will go to the AFC Ajax home to watch the First Team competition. You can play the team at the spectacular Amsterdam Arena one day.

    Qin Xiong stayed alone in the training ground and communicated with the Stadium Administrator. He had to take a bag of football and walked 30 meters in front of the goal. He placed more than 20 footballs in a fan-shaped position, then passed through Free kick training for different angles of the goal.

    Observe, run, shoot, and cycle.

    Qin Xiong Every time the shots are pursued with angles, the football will definitely kick out a clear arc.

    Perhaps it is his own thinking influence, in addition to short-range shots, Qin Xiong in the long-distance free kick, long-range, are mainly curved ball.

    He doesn't like football running in a straight trajectory, and he loves football in the sky through unpredictable parabolic trajectories.

    Therefore, when he practiced free kicking and long-range shooting from an early age, he would have a huge friction when he touched the football with his inner instep, so that the football would spin rapidly after vacating, forming a distinct arc.

    And as you get older and your strength rises, when he kick long distances and kicks away from free, the body will have a clear tilt in the moment that supports the body, in order to ensure strength and balance of the body, although not as Beckham kicks the bass arc when the body tilt is exaggerated as if it is about to fall, but Qin Xiong On the basis of the pursuit of arcs, it is also increasing the guarantee of the speed of the ball.

    Recently, things that have puzzled him have happened.

    If he uses all his strength to shoot the arc ball, the first half of the football is normal during the flight, going out of the outer arc and then turning inward, but the second half has problems.

    The flight path of a football sometimes does not end with an arc, but instead it will appear irregular, a truly unpredictable trajectory, erratic.

    This gives Qin Xiong a feeling: football, not under his control.

    boom!

    Qin Xiong shot a free kick and then witnessed the flight path of the football. After the initial arc rotation, when the apex was reached, the arc of the football still existed, but there was already a tendency to fly straight!

    A strange arc is formed, consisting of a large arc of the first half and a small arc of the latter half.

    boom!

    The football hit the goal beam and flew.

    Qin Xiong looked down and thought about the reason for this phenomenon. This is not a special case, not an accident, but a high probability when he uses all his strength to shoot.

    He tried another foot, reduced his strength, and then saw the football complete the flight path with the arc he was familiar with. There was no such irregular change, and he steadily wraps around the outside and falls into the goal.

    He leaned over and meditated.

    Obviously, the reason for the uncontrollable phenomenon, he found a part, first of all related to the strength of his playing.

    "what is troubling you?"

    Someone suddenly spoke behind him.

    Qin Xiong looked around and saw the famous Van Gaal.

    Qin Xiong politely greets each other: "Mr. Hello."

    Van Gaal asked again: "What are you upset about?"

    Qin Xiong told her the other person's confusion and proved her own complaint through a three-leg free kick. Although there is no irregular running track on one foot, the other two balls show irregularity when flying. traces of.

    Although Van Gaal looks as usual, she is more appreciative of Qin Xiong.

    The first is that the other party is practicing in this Riga. This is a professional attitude. No Manager does not like this player.

    Secondly, he watched Qin Xiong kick out almost 20 free kicks, and Qin Xiong's free kick level made him shine.

    As for the confusion of Qin Xiong, he can really answer.

    He went over to pick up a football and said, "the scientific knowledge involved in football flying in the air is mainly fluid mechanics. Simply put, the football trajectory is not only controlled by you, including positive air resistance, air suction at the rear of the sphere, friction of the surrounding air against football, and the rotational force of the air whirlpool on football, etc. First you have to understand that football is kicked out, that is, the moment after your foot kicks the ball out, the speed of football is the fastest. At a certain speed, the flight trajectory of football is familiar to us, such as curveball, straight ball, football will not produce too much, or even if there is a trajectory change, but we look at the naked eye to ignore the change of subtle deviation, but when the speed of the ball reaches fast enough, or break through a tipping point, The trajectory of football under the influence of various air resistance, friction, rotation force, suction, the deviation will produce qualitative change, so that our naked eye can be clearly observed, so, congratulations, your free kick level, has stepped into the threshold of knuckleball, If you want to play this free kick in the future with unpredictable tracks at the fall, my advice is to reduce the pursuit of arcs, focus more on force outbreaks and footwork control, and keep football as still as possible. ”

    Qin Xiong is slightly frowning. He doesn't like football to stay still when flying. Such a trajectory has only a straight line, lack of change, or a beautiful sense of line.

    But he decided to listen to Van Gaal's suggestion and try it out.

    Run and support the body to ensure that the football is in a non-rotating state.

    boom!

    Football is like a cannonball volley.

    The ball speed is amazing, blinking!

    Qin Xiong and Van Gaal watched the trajectory of the football flight. When the football in the upward flight suddenly fell, it produced a erratic trajectory. If it was observed at a slow speed of 10 times, a snake was produced in the short distance in front of the door. Irregular trajectory!

    Qin Xiong was a little surprised to open his mouth.

    Perhaps, he didn't like the straight line when he was a child, because his strength was not enough. No matter how much he played, how much power he used, football was just a straight line that was generally consistent.

    But now, his power is enough to make football play an irregular trajectory on fluid mechanics during flight!

    Van Gaal laughed at the side: "Because the ball is still, the ball is only subjected to the action of the streamlined surface pressure difference and gravity during the movement, and it is not affected by the air pressure generated by the spin of the sphere, so that the erratic line can be generated. ,you're great."(A good activity to drop the pie in the sky, cool mobile waiting for you to take!
