In a study of injuries sustained in junior league handball, all injuries during 685 hours of play sustained by 7 320 players have been registered in a cup tournament. Junior handball appears generally to have a very low injury risk, but with a clearly indicated tendency towards more injuries in the higher age group and fewer injuries in the lower age group and among girls. The more serious injuries sustained during a junior handball tournament are carefully registered by the tournament doctor, but the less serious injuries must, if so wished, be registered by other means, for example by telephone call or postal report after the tournament games.
