Soccer exposes players to head injuries and involves repeated intentional head impacts through heading the ball. Our objective was to investigate the rate of both intentional headers and involuntary head impacts in semiprofessional male soccer players during one season. In this prospective cohort study, we followed 54 men (16-35 years) playing in two soccer clubs participating in the same regional French championship throughout the 2017-2018 season. All head impacts that occurred in competitive games were analyzed using video recordings. Player position, game exposure, referee's decision were also reported. Head impact incidence rate (IR) per 1000 player-hours, with the 95% confidence intervals (CIs) were calculated. Results: Headers IR was 3584.7 per 1000 player-hours (95% CI = 3431.9, 3737.5). Forwards and center-backs performed a higher number of headers. Involuntary head impacts IR was 44.1/1000 player-hours (95% CI = 27.1, 60.9). Just under half led the referee to stop playing time for a caregiver examination. Three concussions with a loss of consciousness after a head-to-head impact in a heading duel were recorded. Conclusions: Intentional headers were relatively common, contrary to involuntary head impacts that were however mainly due to heading duels. Head-to-head impact should lead to a systematic exit from the game for suspicion of concussion.
足球使运动员头部受伤，并通过头顶球导致重复的故意头部撞击。我们的目的是调查一个赛季中半职业男性足球运动员的故意头部撞击和非故意头部撞击的发生率。在这项前瞻性队列研究中，我们对参加同一法国地区锦标赛的两个足球俱乐部的 54 名男子（16-35 岁）进行了随访。使用视频记录分析了所有在竞技比赛中发生的头部撞击。还报告了球员位置、比赛暴露、裁判的决定。计算了每 1000 名球员小时的头部撞击发生率（IR），并给出了 95%置信区间（CI）。结果：头部撞击的 IR 为 3584.7/1000 名球员小时（95%CI=3431.9，3737.5）。前锋和中后卫完成了更多的头顶球。非故意头部撞击的 IR 为 44.1/1000 名球员小时（95%CI=27.1，60.9）。大约有一半的球员导致裁判停止比赛，让护理人员进行检查。在一次头顶球的头部碰撞中发生了 3 次脑震荡，导致意识丧失。结论：故意头部撞击相对常见，而非故意头部撞击主要是由于头部碰撞所致。头部碰撞应导致系统地退出比赛，以怀疑脑震荡。
