How can I kick a banana ball? How to kick a banana ball

Of course, you have to work hard, but here are some suggestions.

Curl shot from the outside of the foot.

Curved banana balls.

Scope of use: Shots from medium to long distances that bypass the opponent's block. ·

Technical points: run to the ball in diagonal steps, when standing close to the side of the ball, lift the leg and twist the body to lock the eye, use the outside of the foot to volley the ball outside the third of a point, and close the knee after shooting.

Complete the shot.

A little secret: toe down, use the instep to pull the ball on the outer plane, it is easier to form the ball outward bend castration, the greater the shooting force, the greater the arc, and the weaker the strength is difficult to surround the opponent.

Incurved banana balls.

Scope: Medium-range shots that bypass the opponent's block.

Technical points: run diagonally to the ball, stand on the side of the ball, lift the leg to lock the eye, use the inside of the foot to volley the ball outside three points, twist the body during the hitting process, and shoot the ball naturally bent out.

A little tip: the toes are forward and upward, make good use of the inside of the boot to touch the ball, it is easier to grasp the direction of the ball, too much shooting force will cause the ball to fly away, weak strength and more difficult to get around the opponent.

The kicker's own experience suggests that the inside of the foot is the position of the forefoot. There are two things to remember: first, the part that touches the ball is the lower part of the outer side of the sphere, which is about two-thirds of the total area of the lower semicircle of the sphere.

Second, you must know how to exert power, the key to spinning the ball is to master the strength, according to the position of the penalty spot from the goal, choose your own strength. In addition, when you can't fully grasp it at the beginning, you can take a look at Xiaobei's serving style and lean your body back as much as possible, similar to picking the ball on the net.

Inner instep: short-distance running (the master can not do it, for example, Xiao Luo sometimes does not need to run, directly get up with his feet), kick the lower right part of the ball with the instep connected by the big toe and the ball of the foot (not the middle and lower part of the kick, otherwise the lateral horizontal plane of the ball is a straight line, there will be no arc).According to physical mechanics, the ball will deflect towards your left side.

Outer instep: Short run-up (same as above), kick the lower middle left part of the ball with the instep above the fourth toe. According to physical mechanics, the ball will deflect to your right.

The above method is for the right foot only.

This can be practiced! Kick the ball in the bottom left corner when kicking! You can go and see how to kick the shell arc. World Football has done an episode of the program, you check and decipher the shell-style arc or (full moon scimitar) on **, there are all!

The banana ball is played as follows:

1. Run-up; It is advisable to run a 90-degree run between 16 and 20 metres from the goal, so that the ball is less powerful but has a stronger arc. It is advisable to run 45 degrees from a goal when the penalty is 20 metres above the goal, so that the kick is more powerful but not spinning.

2. Use the inner instep to draw the ball, so that the contact area between the instep and the ball is as small as possible, and the body is relaxed and stretched.

3. Hitting position; When kicking a banana ball, you must try to kick the outside bottom area of the ball, that is, the lower left side of the ball with your left foot and the lower right side of the ball with your right foot.

Banana balls are not uncommon at the World Cup and in the club leagues, but they still deserve to be an after-dinner conversation among fans. Because kicking a banana ball requires a player to have a very good ball control ability and just the right amount of kicking power. From a physical point of view, the so-called banana ball is a ball that the kicker kicks out of the ball that spins sideways by friction, and thus affects the trajectory of the ball.

Banana Ball uses Bernoulli's principle in fluid mechanics: in a fluid system, such as air and water, the faster the flow velocity, the less pressure the fluid will generate. Combined with the example of a banana ball, when the ball rotates while flying in the air, it will drive the thin layer of air on its surface to rotate at the same time, and the linear velocity of the rotation of the thin layer of air on one side and the forward velocity of the ball are superimposed, so that the oncoming air flow is subject to greater resistance. On the other side, the opposite is true, where the linear speed of rotation and the forward velocity weaken each other.

According to Bernoulli's principle, one side with a high air velocity forms a low-pressure area and the other side forms a high-pressure area relative to the translational motion of the football. The result of the pressure difference between the two sides of the ball is that the ball is subjected to a resultant force from the high pressure area to the low pressure area. This resultant force causes the ball to deviate from the direction of the original straight line, thus causing the wonderful phenomenon of "banana ball".

How to kick a banana ball? I'll take you through it here.

01 Run, keep a distance of about two meters before kicking the ball, keep the stride not too big and not too small, about three steps to the ball, and step on the left side of the ball with your left foot close to the football.

02 Lean to the left, after stepping on the left foot, it is slightly like tilting to the left, tilting helps the human body to adjust the posture, like a bow and arrow, there is a longer leg swing distance, and the strength is improved.

03 Collect the rock imitation leg, the right leg is naturally retracted, the ankle is tightly tensed, and the hook is back, and after retracting, draw an arc and hit the ball in the process of tilting.

04 Explosive football, which creates a trajectory with the swing of the thighs and calves, eventually hits the lower middle of the ball and rubs it upwards, creating a banana ball with force and rotation.

In a scenario simulation, the researchers found that in order for a free kick with a speed of more than 100 km/h to avoid a human wall (assuming five opposing players with a height of 5 meters side by side at a distance of about 9 meters) to successfully shoot, the angle between the ball and the ground must be controlled between 15° and 17°.

In other words, there is only an accuracy range of 2° (when kicking a sidespin arc with a speed of 8 revolutions per second at a distance of 25 meters from the goal). In the case of a soccer ball, at a speed of 90 kilometers per hour, it spins 8 times per second, and the ball will bend more than 3 meters in this distance.

The key to kicking the arc is that the landing point is at the position that deviates from the center of the ball, and the greater the deviation from the center of the ball, the faster the speed of the ball. Some researchers say that good free-kick players such as Andrea Pirlo will tilt the axis of rotation of the ball at a greater angle than the side spin, allowing Magnus to tilt downwards to kick the ball "fast, bent sharply and sinking sharply".

The sudden turn of the ball left the players present, especially the French goalkeeper, unable to react. The most beautiful, iconic and physics-defying free kick in history is known as the "Banana Ball". French physicists studied this for several years and finally explained the problem with the "Magnus effect".
