Heading the soccer ball may be bad for young brains

    The question of whether young children should use their heads on the soccer field has been a debatable one in recent years. In 2015, U.S. Youth Soccer, the organization that oversees most of the American leagues for children and teenagers, announced a ban on heading in games and practices by participants younger than 11, citing concerns that the play might contribute to brain concussions.
    In response, some soccer authorities pointed out that young players would be late to learn an essential soccer skill and that concussions from heading are rare in that age group.
    Now a study presented last month at the annual convention of the American College of Sports Medicine may help quell doubts about the current regulations, which went into effect in 2016.
