As we all know, because only uniform jerseys can be worn on the court, many stars often only use hairstyles as a place to show their individuality.
Washing, cutting and blowing is just the basics. Long hair should be soft and elegant, and short hair should be carefully styled. Reggae braids, moxicans and explosive heads are all common sights.
If you watch the ball long enough, you can even find that not only green grassland appears on the top of the players, but also a pack of instant noodles.
So the question arises. Heading is a very important technical action in a football game. Will various hairstyles with different lengths or short shapes affect the header?
I searched Chinese and foreign networks and found that there are quite a few fans who are curious about this snake essence problem.
This is from a famous domestic Q&A website.
This is from a famous foreign question and answer website.
Among the answers to these questions, most of the respondents said categorically: No. But it is difficult for them to come up with scientific theories and related evidence, and it is more of a judgment derived from experience.
You see, it’s also a bald head. Trezege has more headers than Henry, right? It’s also unkempt, Valderrama doesn’t even bother to run, let alone jump, and Fellaini is basically a high-altitude bomber, right?
But such arguments cannot fully convince me. So, in the spirit of seeking truth from facts (wu) technique (liao), I had a bold idea: I should just shave my head and put on various wigs for a test?
However, just as I was about to put it into action, I suddenly found a magical English article that saved the hair volume that had been diminished due to middle-age greasy.
There is a blog called "Discovering Interesting Life Skills", daily updates of tests and experiments that seem to be amusing but contain rich life philosophy. And in a blog last year, the test content is: Will hairstyle affect the level of header?
The first step is to establish a theory.
Regardless of the heading power that has nothing to do with the hairstyle, the quality of the header after receiving a high-altitude pass is mainly affected by two factors. One is the rebound force after the ball contacts the skin, and the other is the friction force when the ball contacts the skin/hair. According to Newton's second law of motion, the rebound force should be lower than the force when receiving the ball.
The second step is to test the rebound force.
The tester found a head model prop and tested the bounce height of the football after touching the head under the three cases of bald, short wig and shaggy wig. In order to reduce the test error caused by artificial force, he also designed a simple mechanical device to ensure the same force when kicking off.
After a lot of data verification, he came to the following conclusions: the height of the ball bounces when bald, followed by short hair, and the lowest unkempt. Therefore, the rebound force is inversely proportional to the length of the hair.
The third step is to test friction.
How to try this? Director Bi shaved his hair, and then personally tested the heading accuracy of bald, short wig and shaggy wig to measure the impact of friction on the level of heading.
In order to get close to the real game state, he also applied petroleum jelly to the outer layer of his bald head to get close to the shiny players on the court.
Then, stand in three different positions and start shooting with a header. Like this.
And this way. (I always feel as if I saw Zhang Wei)
Based on the collected data, the conclusion is as follows: in the case of sweating, the bald head is the most difficult to hit the target, the short hair is better, and the shaggy head is the easiest to control. Therefore, the friction force is proportional to the length of the hair.
The final summary statement is ready to come out:
Based on this theory, he believes that the most ideal hairstyle for a striker should be the following.
Do you think this is over? How! What! can! can!
The blogger put the English version of Dao Bi's "Experimental Conclusions" on the social platform, and it caused a small range of heated discussions.
He pointed out that this test has a major flaw, that is-both wigs have bangs the same length as the hair, which will have a serious impact on the test results when heading in place.
However, in the course of a normal game, a standard header is mainly used to head the ball. Players are afraid of blocking the line of sight and rarely leave longer bangs. Even if they are generally in the process of sprinting and jumping, they are blown away by the wind. Up.
In addition, the speed of the ball in the actual game is much faster than the toss in this test. At high speeds, the influence of hair on elasticity and friction is far less obvious.
So, except for the special case of rubbing the ball against the back of the head with the Tianling cover,
The crowds onlookers said that experts really know a lot! You see, even if it is the famous fluffy bomber Fellaini, his forehead is not covered by much hair.
And no matter how much the stars like to apply hairspray to their heads before the game, there are very few Japanese iron bangs that ignoring the gravity of the earth.
At the same time, for those famous Airmaster players, whether it is Fellaini, Klose or Ronaldo, the hair length and styling obviously did not affect their scoring efficiency. At most,
In summary, the hairstyle does not directly affect the header, but the header definitely affects the hairstyle.
In January of this year, former Paris star Ben Alfa signed a six-month short-term contract with La Liga team Valladolid. At the home court debut ceremony, he was asked by reporters to make a heading move after he finished the traditional ball bumping. Ben Alpha smiled and waved his hand in rejection: "I don't like headers because it will ruin my hairstyle."
As the saying goes, the head can be cut off and flowed, and the hairstyle can't be messy.
Now you know why Ronaldo uses so much hair gel every game, right? Hair style and header are indispensable!
See it, this is the real professional!
