Head impacts have been studied extensively in football, but little similar research has been conducted in men's lacrosse. It is important to understand the location and magnitude of head impacts during men's lacrosse to recognize the risk of head injury.
Descriptive epidemiology study set on collegiate lacrosse fields. Eleven men's lacrosse players (age=20.9±1.13years, mass=83.91±9.04kg, height=179.88±5.99cm) volunteered to participate. We applied X2 sensors behind the right ear of participants for games and practices. Sensors recorded data on linear and rotational accelerations and the location of head impacts. We calculated incidence rates per 1000 exposures with 95% confidence intervals for impact locations and compared the effect of impact location on linear and rotational accelerations with Kruskal-Wallis tests.
We verified 167 head impacts (games=112; practices=55). During games, the incidence rate was 651.16 (95% confidence interval=530.57-771.76). The high and low incidence rates for head impact locations during games were: side=410.7 (95% confidence interval=292.02-529.41) and top=26.79 (95% confidence interval=3.53-57.10). For games and practices combined, the impact locations did not significantly affect linear (χ=6.69, P=0.08) or rotational acceleration (χ=6.34, P=0.10).
We suggest further research into the location of head impacts during games and practices. We also suggest player and coach education on head impacts as well as behavior modification in men's lacrosse athletes to reduce the incidence of impacts to the side of the head in an effort to reduce potential injury.
头部撞击在橄榄球运动中已得到广泛研究，但在男子长曲棍球运动中类似研究较少。了解男子长曲棍球运动中头部撞击的位置和强度对于认识头部受伤风险很重要。
在大学长曲棍球场地进行描述性流行病学研究。11名男子长曲棍球运动员（年龄=20.9±1.13岁，体重=83.91±9.04千克，身高=179.88±5.99厘米）自愿参与。我们在参与者右耳后方佩戴X2传感器，用于比赛和训练。传感器记录线性和旋转加速度数据以及头部撞击位置。我们计算每1000次暴露的发生率，并给出撞击位置的95%置信区间，同时用Kruskal-Wallis检验比较撞击位置对线性和旋转加速度的影响。
我们确认了167次头部撞击（比赛=112次；训练=55次）。比赛期间，发生率为651.16（95%置信区间=530.57 - 771.76）。比赛中头部撞击位置的高发生率和低发生率分别为：侧面=410.7（95%置信区间=292.02 - 529.41）和顶部=26.79（95%置信区间=3.53 - 57.10）。对于比赛和训练的综合情况，撞击位置对线性加速度（χ=6.69，P=0.08）或旋转加速度（χ=6.34，P=0.10）没有显著影响。
我们建议进一步研究比赛和训练期间头部撞击的位置。我们还建议对男子长曲棍球运动员和教练进行关于头部撞击的教育，并改变运动员的行为，以减少头部侧面撞击的发生率，从而降低潜在受伤风险。
