How did Ronaldo s lift ball come out?

The elevator ball touches the ball and the way it touches the ball is also very special. The free-throw player needs to use his calf to exert a quick force, and the side foot uses the top of the foot to slam the middle and lower end of the ball. Due to the speed of the ball, once the ball is kicked high, it cannot get the same unaffected falling time as an ordinary curveball, so the free throw must control the power part and try to depress the line of the ball to get a good effect, otherwise it will deviate a lot from the target.

The elevator ball kicked by Ronaldo was often 120 yards faster, the line was very low, just over the human wall, and there were almost no traces of gravity in the whole process. This is also related to his trademark free throw action, which is measured to the point where the ball is separated from the feet before the ball, and there is a customary knee-jerk pause before touching the ball during the run, which is used to rivet the calf of the right leg, and then slam the force after aiming at the spot. Capello once said of Ronaldo's lift ball that perhaps he had found the most effortless way to make free throws.

The implication is that as long as the foot strength is strong enough and the ball speed is fast enough, the ball can be punished. However, the essence of the elevator ball is not in the speed of the ball, but in the stationary body of the ball mentioned at the beginning, the speed of the ball is only derived from the force. It is precisely because of the stationary nature of the ball that the ball is only affected by the effect of the streamlined surface air pressure difference and gravity during the movement, and is not affected by the air pressure generated by the spin of the sphere, so that the erratic line can be generated.

Ronaldo's shot can be explained by Bernoulli's law. When Ronaldo touches the ball with his foot, it spins at high speed and rushes forward. This causes the air particles below the front of the ball to lose pressure, giving the ball the downforce to fall rapidly as it crosses its highest point.

Scientifically, we call this the Magnus effect, which is very similar to the topspin in tennis.

Moreover, Ronaldo trains very hard, and after each training, he works overtime, and during training, he deliberately presupposes two meters on the human wall, that is, the international standard meter is raised to the meter.

mastered the technique and trained hard to finally achieve Ronaldo's elevator ball.

Cristiano Ronaldo's elevator ball was kicked with his feet!

Well, the power is very high, and the ball is mainly rubbed out, so he has a weird arc, which makes the goalkeeper unguardable.

The main thing is to use the knee to exert force, kick the middle and lower part of the ball with the arch of the foot, quickly retract the force after hitting the ball, when the quality is high, the ball itself will hardly produce any rotation during the flight, but it will move sideways and move up and down, mainly for more training, to practice this kind of ball, you must first train the muscle groups near the knee, or it is not easy to strain.

Cristiano Ronaldo offered two types of free-kicks in the game.

One is a slight arc of the ball, which is not in the center of the ball, but a little to the side of the center, and wraps the ball with the inside of the foot to create spin.

Once the spin is generated, it puts different pressures on the inside and outside of the ball, and the ball will fly towards the less stressed side to form an arc, which can go around the human wall, and the goalkeeper will not have time to react when he sees the ball.

The second is not to spin the free kick, which is what the landlord wants to know.

The secret lies in the gaps on the surface of the ball.

These gaps don't have much effect on the ball spinning, but when the ball doesn't spin, the gap on one side of the ball is affected by air resistance, while the other side is not, so the ball deviates from its original trajectory and the goalkeeper can't tell.

These things should be well understood by the landlord if he is good at physics.

Typing is very hard, the landlord must understand.

In the goalkeeper's view, the ball is flickering left and right, and accompanied by a rapid decline, not completely does not turn, just slightly turning, due to the splicing gap on the ball, so that the air flows unevenly on the surface of the football, so the trajectory of the elevator ball will deviate a lot from the ordinary free kick trajectory.

Straight up and down in a straight line, there will be a small arc, mainly in the grasp of power and the touch of the ball, the ball **.

The third toe slams under the ball in an instant.

It's like the instep of the foot, but it's not... The force is like the lifting action of a table tennis ball... Dude, you can try it yourself.

Ronaldo's footwork is precise and powerful.

When he plays, he has very little swing of his feet, which shows that he has excellent explosiveness, so if you want to imitate it, you have to have a lot of power and good explosiveness.

He kicks free kicks, generally with the right instep and the outside of the instep, the right instep is easier to exert force, and the outside instep is more difficult to learn, it is recommended that you practice the free kick with the right instep first.

In addition, when kicking the ball, you should kick the middle and upper part of the ball, so that the ball can be high and floating. (This is very difficult to grasp).

In the end, of course, it is necessary to combine hard training to be able to play like Cristiano Ronaldo. I wish you success! It's hard to practice. Pull the ball vigorously from the middle and lower part of the ball with the instep of the right foot, from the time the ball touches the ball until it leaves the surface of the foot, the foot needs to have a lifting effect on the ball.

Elevator free kicks, represented by Juninho Jr., Pirlo, Ronaldo. Ronaldo himself says he has borrowed from the first two.

Difficulty: 1. The part of the ball that touches the ball, this is difficult to grasp, if it is too close to the lower part of the ball, the foot will poke to the ground.

2. Strength, the leg strength of professional athletes, is unattainable for amateurs, talent + acquired training.

Volleys, if played in the right position, are easier to hit because the ball is in the air and is easier than an elevator free-kick.

It's still not good to practice, I advise you to stand on both feet like a compass. His footwork is called trapezoidal footwork, and the height is uncertain. The threat is big and it's a test for the goalkeeper.

LZ upstairs is the right solution.

There is also Ronaldo's elevator free kick, he will also put the ball on his own valve, so that he feels that when the ball is flying, the line will be higher and more floating, and it is not good for the goalkeeper to judge.

The first is the run-up, Ronaldo's run-up is different from any other team member, he will first stand in front of the ball seriously, and then step back step by step, retreating while measuring the distance of the serve. Ronaldo's retreat distance is often 5 steps, and then the left foot pulls a step to the left, so the Ronaldo running position is formed, which is also compared to the compass by some fans. Before the run, Ronaldo takes a deep breath to focus.

When he hits the ball, the central axis of his body will remain perpendicular to the ground, and the supporting foot will deviate from the central axis of his body by about 50 degrees, forming a perfect angle with the hitting foot and torso. When hitting the ball, Ronaldo's eyes were glued to the ball until he knocked it out. Compared to the running position, Ronaldo's serve is more special.

When Ronaldo touched the ball at the end, he basically used his knees to exert force and press the ball hard. This is also the reason why the free kick sent by Ronaldo has a strange trajectory and a strong fall. The point of impact at the penalty kick is roughly the middle and lower part of the ball, and the effect comes out because of the great strength of his knees.

It takes a lot of explosiveness and skill, of course, this requires innate talent and acquired efforts, and Ronaldo's elevator ball is very harmful to the knee.

Touch the ball between the instep and the toe.

In the World Cup group stage between Portugal and Spain, the 33-year-old veteran Cristiano Ronaldo scored a hat-trick, especially the goal in the 87th minute, which can be called a textbook classic free kick.

In this game, the commentator said it was a typical elevator ball. The lift ball was originally kicked by Andrea Pirlo in the Euro Championship match between Italy and Croatia.

It is characterized by the fact that the ball is fast, does not spin, and suddenly falls after rising in a straight line, which is difficult to understand.

As a kind of banana ball, the elevator ball is a kind of banana ball, because the rotation speed of the ball body is very small, the foot force is almost all acting on the kinetic energy required in the forward direction, the moment the ball volleys into the air to obtain high speed, at the beginning of the ball high-speed straight forward, but as the air acts on the surface of the streamlined ball, any position of the ball can produce a pressure difference, which directly causes the ball to move erratically, left and right, and even up and down.

Cristiano Ronaldo can be described as the master of elevator ball, and has scored from free kicks in many games. Compared with Pirlo, his elevator ball is more powerful and swings more in the air, which can be called Ronaldo's exclusive elevator ball.
