Avery, M, Wattie, N, Holmes, M, and Dogra, S. Seasonal changes in functional fitness and neurocognitive assessments in youth ice-hockey players. J Strength Cond Res 32(11): 3143-3152, 2018-Deficits in balance and strength combined with differing rates of sensory and motor neural development may increase risk of sports-related injury in youth. This study evaluated changes in functional fitness and concussion status over the course of a competitive season in youth ice-hockey players, and examined the relationship between these variables and injury occurrence. Thirty-six participants (8.9 ± 1.1 years) completed preseason and postseason assessments including anthropometric measurements, the functional movement screen (FMS), Lower Quarter Y-Balance Test (YBT-LQ), and a computerized neurocognitive assessment (ImPACT). Paired-samples t-tests were used to compare preseason and postseason data. Independent samples t-tests were used to compare FMS, YBT-LQ, and ImPACT scores between injured and uninjured participants at baseline. The mean composite score of the FMS was not statistically different between preseason (15.1 ± 1.8) and postseason (15.6 ± 2.3, p < 0.16). The YBT-LQ composite score showed a decrease in reach distance scores between preseason (86.10 ± 6.00) and postseason (83.20 ± 5.40, p < 0.001). Neurocognitive assessment scores improved in both the injured and uninjured participants. There were no significant relationships between FMS scores, YBT-LQ, and injury incidence. Results from our study provide insight into changes in functional fitness levels and neurocognitive scores over the course of a season in youth ice-hockey players. These findings provide insight into expected changes over the course of a season and provide context for injury risk monitoring by coaches.
埃弗里、瓦特、霍姆斯和多格拉。青年冰球运动员的功能性体能和神经认知评估的季节性变化。J 力量与体能研究 32（11）：3143-3152，2018 年-平衡和力量的缺陷加上不同的感觉和运动神经发育速度可能会增加青少年运动相关伤害的风险。本研究评估了青年冰球运动员在一个竞争赛季中功能性体能和脑震荡状况的变化，并研究了这些变量与受伤发生之间的关系。36 名参与者（8.9 ± 1.1 岁）完成了 preseason 和 postseason 评估，包括人体测量学测量、功能性运动筛查（FMS）、下四分之一 Y 平衡测试（YBT-LQ）和计算机神经认知评估（ImPACT）。采用配对样本 t 检验比较 preseason 和 postseason 数据。采用独立样本 t 检验比较基线时受伤和未受伤参与者的 FMS、YBT-LQ 和 ImPACT 评分。FMS 的平均综合评分在 preseason（15.1 ± 1.8）和 postseason（15.6 ± 2.3，p < 0.16）之间没有统计学差异。YBT-LQ 综合评分显示 preseason （86.10 ± 6.00）和 postseason （83.20 ± 5.40，p < 0.001）之间的伸展距离评分下降。神经认知评估分数在受伤和未受伤的参与者中都有所提高。FMS 评分、YBT-LQ 与损伤发生率之间无显著相关性。我们的研究结果提供了青年冰球运动员在一个赛季中功能性体能水平和神经认知评分变化的见解。这些发现为赛季中预期的变化提供了见解，并为教练进行损伤风险监测提供了背景。
