Concussions in soccer
Now, the infamous question: does heading a soccer ball cause concussions and brain damage? This has nearly been ruled out completely. Heading a soccer ball does not cause concussions. A concussion comes not from the impact of an object upon the skull itself, but from the whiplash of your neck and head (your brain) against the casing of your skull. It should be noted that most of the research has been done on the professional level.
** Correct technique - player need to strike the ball, don't let the ball strike the player
** Limit repeats - Keep header training to minimum number of repetitions in a row
** Play with age appropriate ball - 5 year olds should not be heading a size 5 ball.
** Consider no heading for players under 12.
