How Different Are Natural Lawns And Artificial Lawns When Exercising?

The recent opening of the World Cup has made football a hot topic in the world. Now let's talk about the lawn of the football field. Nowadays, natural lawn and artificial lawn are mostly used. How are the differences between natural lawn and artificial lawn in sports?
1、 Friction
The friction in football mainly includes the friction between artificial turf and football and the friction between artificial turf and players. Compared with the plant grass fiber of the natural lawn football field, the plastic fiber grass of the artificial lawn football field has greater friction on the football. The football movement on the artificial lawn is more "astringent", that is, the rolling coefficient speed will be slower and the rolling distance will be closer. This will have a greater impact on the players' dribbling and ball control. The rolling distance measurement can be used as a standard to judge the friction force. The best rolling distance is 3~12m, and the acceptable range is 2~14m. The rolling distance of natural turf is 4~15m; The rolling distance of football on artificial turf is 1~10m.
Artificial turf is the most important friction for athletes. On the one hand, athletes will consume too much energy when they play on the artificial turf court with high friction, which will lead to premature fatigue and seriously affect the play of athletes' skills and tactics. On the other hand, in fierce sports, dry friction will make athletes' joints and ligaments bear greater stress, which is easy to cause strain and injury. At the same time, once the athletes fall down or do the sliding shovel and hook, the sports friction will burn the skin. To sum up, friction is an important indicator to evaluate the sports performance and safety of artificial turf football fields.
2、 Elasticity
The elasticity of natural grass and plant fibers is limited, and the elasticity of football on the natural lawn is small. The height of the high-altitude ball or rebound ball will not be very high after landing, which is convenient for players to receive, stop and control the ball. However, the artificial grass in the artificial turf football field is made of plastic fiber, and its elasticity is greater than that of plant fiber, so the high altitude ball or rebound ball will bounce back after landing with great power, which will bring uncertain judgments to the players' receiving, stopping and controlling the ball. The players will predict the rebound height and route of the football in advance, readjust their stopping position, and have a certain change to the players' inherent skills and tactics.
