Sihaiwang: the world cup is coming soon. I believe everyone can't wait. But the kid who loves watching the ball must be curious about one thing. That's why football players like to spit on the ground? Let's have a look
During vigorous exercise, the mouth will secrete more saliva to keep the mucous membrane moist due to the stimulation of open mouth breathing and increased ventilation. Over time, these secretions will air dry, accumulate and become sticky in the mouth, which makes people feel uncomfortable.
But as the subject said, we often see the "uncivilized" behavior in football matches, but it is very rare in other high-intensity sports such as basketball. This interesting difference can be explained in the following aspects:
1、 More sports and saliva in football match
Because of the different positions and ways of sports on the field, and involving other physical confrontations, it's hard to be convincing to use running distance to show that football has more sports than basketball. But we can explain the problem from another point of view: there are many basketball players who play to the age of 40, while the peak period of football players is 25-30 years old, and then the competitive state begins to decline significantly, most of them will retire before the age of 35. In addition to the injury factors, the most direct reason for this age difference is that football games have more sports and higher physical requirements.
The football field needs a lot of long-distance fast running, even a 100 meter sprint, the whole game is equivalent to a constant speed change long run. This state is the most exciting to human body, and athletes will produce more respiratory tract and oral mucus.
2、 Competition system determines the behavior of athletes
Basketball game is about 40 minutes, divided into four sections, each section is about 10 minutes (12 minutes for NBA). There is a break time between sections. In the process of the game, players can be changed in the state of dead ball, and the number of people can be unlimited; while in the 90 minutes of football game, only the first and second half are divided, and there are only three changes during the game.
Obviously, players in basketball games have shorter time of continuous sports and more opportunities of rest. They can drink water, wipe sweat and spit calmly. Football players may rush for 45 minutes when they go on the court, so there are still problems to be solved on the spot.
3、 The influence of competition environment on Athletes' behavior
1. Different floors
Basketball court is a spotless wood floor, stains, sweat, saliva and so on will affect the movement of players' feet, and even cause slipping injury; while football court is grass, players' sports are little affected by saliva and other pollutants.
2. Different air quality
Basketball court is located indoors with high cleanliness, while football court is usually open environment. PM2.5, regardless of the existence of grass dust and dust, will make players' respiratory tract more easily stimulated.
3. Different space sizes
Basketball field is small, players are dense, spitting at will may be spitting on others, and it is close to the audience, under the full view of the public, the indecent behavior will be restricted; while football field is large, it is far away from the audience, without the psychological pressure of people's attention from time to time, players will be more unscrupulous.
To sum up, spitting everywhere is almost one of the 'essential skills' of football players, and it has become a' landscape 'that FIFA can not manage.
