You can observe the way players move furtively across this kinda pitch, the movement of the ball is different from grass, kicking the requires a different technique and timing and the bounce of the ball is unreal because of the hard foundation underneath this type of artificial pitch and that's also one of the reasons that players are wary of jumping and landing on their heels - can cause damage, some of it very serious (if unlucky on the landing) and out injured, long term!
