Previous injury is often proposed to be a risk factor for football injury, but most studies rely on players reporting their own medical history and are thus potentially subject to recall bias. Little is known about the natural variation in injury pattern between seasons.
To study whether prospectively recorded injuries during one season are associated with injuries sustained during the following season, and to compare injury risk and injury pattern between consecutive seasons.
The medical staffs of 12 elite Swedish male football teams prospectively recorded individual exposure and time loss injuries over two full consecutive seasons (2001 and 2002). A multivariate model was used to determine the relation between previous injury, anthropometric data, and the risk of injury.
The training and match injury incidences were similar between seasons (5.1 v 5.3 injuries/1000 training hours and 25.9 v 22.7/1000 match hours), but analysis of injury severity and injury patterns showed variations between seasons. Players who were injured in the 2001 season were at greater risk of any injury in the following season compared with non-injured players (hazard ratio 2.7; 95% confidence interval 1.7 to 4.3, p<0.0001). Players with a previous hamstring injury, groin injury, and knee joint trauma were two to three times more likely to suffer an identical injury in the following season, whereas no such relation was found for ankle sprain. Age was not associated with an increased injury risk.
This study confirmed previous results showing that previous injury is an important risk factor for football injury. Overall injury incidences were similar between consecutive seasons, indicating that an injury surveillance study covering one full season can provide a reasonable overview of the injury problem among elite football players in a specific environment. However, a prolonged study period is recommended for analyses of specific injury patterns.
既往损伤常被认为是足球运动损伤的一个风险因素，但大多数研究依赖球员自述其病史，因此可能存在回忆偏倚。关于不同赛季间损伤模式的自然变化知之甚少。
研究一个赛季中前瞻性记录的损伤是否与下一个赛季所遭受的损伤相关，并比较连续两个赛季间的损伤风险和损伤模式。
瑞典12支精英男子足球队的医务人员前瞻性记录了连续两个完整赛季（2001年和2002年）中个人的暴露情况和导致失能的损伤。采用多变量模型确定既往损伤、人体测量数据与损伤风险之间的关系。
不同赛季间训练和比赛的损伤发生率相似（每1000训练小时损伤5.1次对5.3次，每1000比赛小时损伤25.
