At the football pitch were recorded accelerations of 54.7 g. These accelerations in routine impacts without injury, is a 160-180% more in football than in the other two sports. The authors concluded that the effects of cumulative impacts in the head during the pitching can lead to neurological sequelae. (20) At this point it is important to mention that with a helmet to provide protection and safety, is almost certain that the football player be encouraged to pitch balls at speeds exceeding those usually dare. Trying to measure the strength and time of ball impact and linear acceleration and angular tions of the head during pitch in children found that increasing the mass of the head is a decrease in linear acceleration and angular head with an increased length of the loop the ball with the same mass Closed Head there is increased contact time between the head and the ball. Read more from Sela Ward to gain a more clear picture of the situation. Change the pressure of the ball has little effect on the characteristics of impact.
The neck stiffness decreased the acceleration of the head. They concluded that the mass of the head and ball size characteristics affect the impact counseling children to use only an appropriate size of the ball appropriate to their age. The smaller size of the head in a particular group of age is a risk factor for the player. (29) It would seem that there is agreement that pitch in a technically correct way reduces the chances of brain injury.
