Concussion incidence rates in professional Australian football may be underreported due to the injury classification definition. A myriad of factors contribute to concussion risk; however, there is limited long-term surveillance in Australian football. This study analysed concussion in one Australian football team over an extended period.
Match-play concussion injuries in one team ( = 116 participants) were diagnosed and treated by the team physician over 14 years. Analysis of factors related to concussion including matches played, time of day and season, and return to play provided an insight into occurrence and recurrence rates.
140 concussions were recorded (17.6 per 1000 player match hours). A strong relationship was evident between matches played and concussion incidence ( = 0.70) and match conditions did not negatively affect the concussion rate. Whether an athlete returned to play in the same match or suffered a loss-of-consciousness concussion ( = 0.84), their ensuing rate of concussion was not affected.
Concussion in professional Australian football was related to the number of matches played. Further, neither previous incidence nor loss of consciousness affected future concussion risk. This study provides ecologically valid evidence of the concussion incidence rate in professional Australian football and has implications for the management of athletes sustaining concussion injuries.
由于损伤分类定义的原因，澳大利亚职业足球中脑震荡的发病率可能被低估。众多因素导致脑震荡风险；然而，澳大利亚足球长期监测有限。本研究分析了一支澳大利亚足球队在较长时期内的脑震荡情况。
一名队医在14年期间对一支球队（n = 116名参与者）比赛中的脑震荡损伤进行诊断和治疗。对与脑震荡相关的因素进行分析，包括比赛场次、一天中的时间和季节以及复出比赛情况，以深入了解发生率和复发率。
记录到140例脑震荡（每1000球员比赛小时17.6例）。比赛场次与脑震荡发生率之间存在明显的强关联（r = 0.70），比赛条件并未对脑震荡率产生负面影响。运动员是否在同一场比赛中复出或遭受意识丧失性脑震荡（r = 0.84），其随后的脑震荡率不受影响。
澳大利亚职业足球中的脑震荡与比赛场次有关。此外，既往发病率和意识丧失均不影响未来脑震荡风险。本研究为澳大利亚职业足球中脑震荡发病率提供了生态学上有效的证据，并对脑震荡损伤运动员的管理具有启示意义。
