Football is the most popular sport in the world and the most commercially successful sport. Most viewers do not have the opportunity to buy tickets to watch the football game live, and can only watch it through TV broadcasts. When spectators watch a football match, they always think that the lawn of the football match must be real grass. But this impression is actually incorrect. Any football game that can be broadcast, its venue. It is not necessarily a real natural lawn, it may also be an artificial lawn.
1. FIFA's regulations and requirements for turf.
According to the official document of FIFA, three types of turf can be used in official football matches, namely artificial turf, natural turf and mixed turf. Regardless of the type of turf, as long as it meets the document quality standards, it can be used in regular FIFA competitions. Since the most authoritative FIFA stipulates this, it can be said with certainty that it is impossible for every broadcasted game to use real grass.
Second, the requirements of artificial turf.
There are two quality levels for artificial turf for football. And high-level lawns can be used for international-level competitions, the most typical of which is the World Cup. Artificial turf uses artificially made materials to simulate natural grass. But to achieve these indicators: the durability of the turf surface, the response of the football on the surface, and the ease of movement of the players on the turf. These three indicators must be measured in the laboratory and can only be used when the conditions are met.
Third, the advantages of natural lawns.
Although the current artificial turf is close to natural grass, there are still shortcomings. The artificial turf has a lower coefficient of friction, which makes the ball move faster on it, and the rebound force is greater. It is not easy to control and it is impossible to make wonderful movements. And artificial turf does a better job of protecting players. The most important thing is that natural turf is actually cheaper than artificial turf. However, in terms of maintenance, natural lawns require a lot of money to maintain.
