Head impacts in American football may lead to brain injuries called concussions. To study head impacts in young people who play American football, we collected data using sensors in mouthguards worn by young American football players. The sensors counted the number of hits and bumps to the head (head impacts) that players of American tackle and flag football got during the football season. We found that tackle football players had about 15 times more head impacts during a game or practice than flag football players had, and 23 times more hard head impacts. Learning more about head impacts in young American football players can help scientists find ways to lower the chances of concussions and other injuries. That way, kids can enjoy the benefits of sports while keeping their brains safe.
美式橄榄球运动中的头部撞击可能会导致一种名为脑震荡的脑部损伤。为了研究参与美式橄榄球运动的年轻人的头部撞击情况，我们通过年轻美式橄榄球运动员所佩戴的护齿中的传感器收集数据。这些传感器统计了参与美式擒抱橄榄球和腰旗橄榄球的运动员在橄榄球赛季中头部受到撞击和碰撞（头部撞击）的次数。我们发现，在一场比赛或一次训练中，参与擒抱橄榄球的运动员受到的头部撞击次数大约是参与腰旗橄榄球运动员的15倍，而受到的严重头部撞击次数则是其23倍。更多地了解年轻美式橄榄球运动员的头部撞击情况有助于科学家找到降低脑震荡和其他损伤几率的方法。这样，孩子们就能在保持大脑安全的同时享受运动带来的益处。
