I believe that many people will kick the ball on the artificial lawn. They all know that there are some differences between the artificial lawn and the natural lawn. After all, it is two different materials. Each has its own advantages and disadvantages. At present, the global football league matches are basically carried out on natural lawns, but with the artificial lawns being favored everywhere, many clubs have used artificial turf as the main venue for the competition, especially universities and colleges. And the amateur league is the world of artificial turf, which also has a lot of problems, such as playing on the artificial turf field, how much is the amount of football inflatable? Is it the same as the natural grass field?
For many amateur football fans, it may be that the amount of ball inflation does not have any effect, but the answer is no. Because the artificial turf field is harder than the natural grass field, the elasticity is larger than the natural grass field, and the elasticity of the landing is fast. The resistance of the football on the artificial turf field is relatively small. If it is the same football, the artificial turf The football on the field is more uniform than the natural grass field, so no matter what kind of football, don't inflate too much. If the inflation is too full, it may cause the football to rebound faster on the landing. The player chasing the football to increase the athlete's movement, plus the harder venue, there are great restrictions on various skills, so the chance of injury to the player is also increased. Big.
According to the general game ball, the weight of the ball should not exceed 450 grams or less than 410 grams at the beginning of the game. After inflation, the pressure should be equal to 0.6 to 1.1 at atmospheric pressure (at sea level), which is equivalent to 600-1100 g/cm. This is the standard for general natural grassland balls. If it is on artificial grass, it can be correspondingly reduced to keep the ball's elastic speed. So this corrects a lot of people knowing how much the ball is inflated when playing in different venues. It is not the same as saying that it is full, and the amount of inflation directly affects the smoothness of the ball speed.
