Heads Up!

    In November，the US Soccer Federation，the biggest soccer organization in the US introduces new rules to make the sport safer for young players．This organization

announced that players on its teams who are 10 or younger are no longer allowed to head the ball．Players aged from 11 to 13 have limits on how often they can practice heading．The new rules are designed to prevent kids from getting concussions﹣injuries caused by a blow to the head that shakes the brain inside the   skull（头骨）．Common symptoms（症状） include headaches and dizziness．

    A DANGEROUS MOVE

    Heading the ball can be one of the riskiest parts of soccer．Sometimes the force of hitting the ball with their heads gives players concussions．But more often，players receive concussions when they jump to head the   ball and accidentally knock heads with other players or fall and hit their heads on the grass．

    "More concussions happen during the act of heading than any other action in soccer，"explains Dr．Robert Cantu，an expert on brain injuries．
