Actually, it's mainly commercial interests.
The first FIFA World Cup was held in Uruguay in 1930, with the final being played between the host country, Uruguay and Argentina. In order to dispel the controversy, the two halves of the final were played with soccer balls provided by Argentina and Uruguay. The top row from the left is a style ball used in the first half.

It's just that the pattern has changed, and it's fashionable.
-
Football in each World Cup will continue to improve with the development of the times and the advancement of science and technology.
Another important reason for this to be able to kick some unbelievable balls is that sports products (adidas, Nike, etc.) invest a lot of money in football design in order to be able to better promote the products they produce.
-
It can't be the same all the time, right? It's all boring.
-
The World Cup is like a college entrance examination paper.
Do you think the same exam paper will be out in 2 years?
-
Because production technology is advancing!
A cycle of four years. Adidas will have new technology incorporated.
-
A different taste, a different style.
-
The new goalkeeper is not easy to adapt, and there are many goals to attract the audience.
-
It's going to change! The average soccer ball is made of 32 balls that are thermally bonded together and have a higher roundness (its roundness is caused by the pressure in the body stronger than one atmosphere).
After the football is kicked, the kicked place undergoes a slight deformation, although the gap in the middle of the piece of the ball skin of a better football can increase its conductivity, but it is impossible to completely eliminate it. The result is only an increase in the pressure in the ball, and of course the volume is small.
-
The volume becomes smaller when kicked, and it does not change after kicking, but the mass is fixed.
-
Yes, because when you shoot a goal, hitting the soccer ball with your foot will expel some gas.
-
After being pressurized, it definitely becomes smaller.
-
Just get your speed and the power to touch the ball well. Practice more, cross the outer instep with the inner instep. I've been playing for a few years now. It's not good to be a defender, but it's definitely sure to pass, and hehe, it's starting to blow again.
-
Touching the ball is light, the strength is mastered, and the key is to practice more.
If you are playing live, press the C button while dribbling and change direction.
-
There should be a amount of advance, the running speed is adjusted with the change of ball speed, and the speed is not required when changing directions, the key is to shake the opponent's center away.
-
Because the angle of the kick is oblique and the kick is forceful, so to speak.
-
If you miss it, you need a little luck, but if you play football for 100 years and play every day, you should be guaranteed to play a lot, hehe.
-
Because the door frame is closest to the goalkeeper, the relationship is good, so I can help.
-
There are 1,000 ways to kick a goal, but they chose the one that can't be kicked (the narrator's words).
-
Is it always into the net?
Do the task,
-
The force on the top of the head not only changes the direction of the object's motion, but also changes the speed of the object's motion.
It's very simple, don't use the instep to pump when you kick, use the outer instep or the inner instep to rub the ball, then the ball will spin in the air, and the rotation will cause the density difference between the air on both sides of the football, and the ball will shift to the side with less density, forming an arc, commonly known as a banana ball. >>>More
You can take a look at the teaching**, there are outer insteps and inner insteps, how to rub them out, very detailed, learning**, in need of hard practice, I wish you success, the next Messi, the next ball king, thank you, come on, good luck!
Silly!! This question is also asked!!
Soccer soccer. You don't have to kick and touch it with your hands!! >>>More
Your football is just so beautiful.
The tackle in football is a technical action, which has been developed for many years. >>>More
Step on the ball with the ball of your forefoot on your toes and pull it back.
