体育运动中的内因性事故,大多数由潜在性器质性疾患所诱发。此问题在运动员健康管理和预防事故的技术指导上,都是很重要的。最近对日本中小学学生死亡事故的调查表明,突然死亡占死亡人数的一半以上,其中有2/3又属于运动死亡。这里的猝死原则上是指发病24小时以内的死亡,其中大部分又是在10分钟以内死亡的病例,不包括外伤性死亡。因为缺乏解剖记录,死亡原因不可能做到绝对可靠,但其中80％以上死亡于 Endogenous accidents in sports, most of which are induced by underlying organic disorders. This issue is important in the technical guidance of athlete health management and accident prevention. A recent survey of Japanese school fatalities shows that sudden deaths account for more than half the death toll, and two thirds of them are also sports fatalities. Sudden death here refers in principle to the death within 24 hours of onset, most of which are deaths within 10 minutes, excluding traumatic deaths.
