Player-to-player contact is the most frequent head impact mechanism in collegiate ice hockey. Training with three-dimensional multiple-object tracking (3D-MOT) could potentially reduce the quantity and severity of head impacts by enhancing player anticipation of these impacts. The purpose of this study was to evaluate the efficacy of 3D-MOT training to reduce the numbers of head impacts sustained by National Collegiate Athletic Association Division III men's and women's ice hockey players. Collegiate men's and women's ice hockey players (N = 33; men = 17, women = 16) were randomly assigned to a 3D-MOT group (n = 17) or a control (C) group (n = 16). Head impacts were monitored during practices and games, and 3D-MOT training occurred twice per week for 12 weeks throughout one regular season. 3D-MOT forwards sustained head impacts with greater mean peak linear acceleration (3D-MOT = 41.33 ± 28.54 g; C = 38.03 ± 24.30 g) and mean peak rotational velocity (3D-MOT = 13.59 ± 8.18 rad^.sec⁻¹; C = 12.47 ± 7.69 rad^.sec⁻¹) in games, and greater mean peak rotational velocity in practices versus C forwards (3D-MOT = 11.96 ± 6.77 rad^.sec⁻¹; C = 10.22 ± 6.95 rad^.sec⁻¹). Conversely, 3D-MOT defensemen sustained head impacts with a mean peak rotational velocity less than that of C defensemen (3D-MOT = 11.54 ± 6.76 rad^.sec⁻¹; C = 13.65 ± 8.43 rad^.sec⁻¹). There was no significant difference for all other parameters analyzed between 3D-MOT and C groups. Player position may play an important role in future interventions to reduce head impacts in collegiate ice hockey.

视觉训练作为减少大学冰球赛季亚脑震荡头部撞击的潜在干预措施的试点研究的意外发现

球员之间的接触是大学冰球比赛中最常见的头部撞击机制。使用 3D 多对象跟踪 (3D-MOT) 进行训练可以通过增强玩家对这些影响的预期来潜在地减少头部撞击的数量和严重程度。本研究的目的是评估 3D-MOT 训练的功效，以减少美国大学体育协会 III 区男子和女子冰球运动员头部撞击次数。大学男子和女子冰球运动员（N  = 33；男性 = 17，女性 = 16）被随机分配到 3D-MOT 组（n  = 17）或对照组（C）组（n = 16)。在练习和比赛期间监测头部撞击，并且在一个常规赛季中每周进行两次 3D-MOT 训练，持续 12 周。3D-MOT 以更大的平均峰值线性加速度 (3D-MOT = 41.33 ± 28.54 g; C = 38.03 ± 24.30 g) 和平均峰值旋转速度 (3D-MOT = 13.59 ± 8.18 rad ^. sec ^-1 ; C = 12.47 ± 7.69 rad ^. sec ^-1）在比赛中，并且在练习中的平均峰值旋转速度与 C 前锋相比更大（3D-MOT = 11.96 ± 6.77 rad ^. sec ^-1；C = 10.22 ± 6.95 rad ^. sec ^-1）。相反，3D-MOT 防守队员以低于 C 防守队员的平均峰值旋转速度持续头部撞击（3D-MOT = 11.54 ± 6.76 rad ^. sec ^-1；C = 13.65 ± 8.43 rad ^. sec ^-1）。3D-MOT 和 C 组之间分析的所有其他参数没有显着差异。球员位置可能在未来的干预措施中发挥重要作用，以减少大学冰球比赛中头部的撞击。
