The aim of this study is to investigate the differences between select on-ice measures using inertial movement sensors based on match outcome, and to determine changes in player movements across three periods of play. Data were collected during one season of competition in elite female ice hockey players (N = 20). Two-factor mixed effects ANOVAs for each skating position were performed to investigate the differences in match outcome, as well as differences in external load measures during the course of a match. For match outcome, there was a small difference for forwards in explosive ratio ( = 0.02, ES = 0.26) and percentage high force strides ( = 0.04, ES = 0.50). When viewed across three periods of a match, moderate differences were found in skating load ( = 0.01, ES = 0.75), explosive efforts ( = 0.04, ES = 0.63), and explosive ratio ( = 0.002, ES = 0.87) for forwards, and in PlayerLoad ( = 0.01, ES = 0.70), explosive efforts ( = 0.04, ES = 0.63), and explosive ratio ( = 0.01, ES = 0.70) for defense. When examining the relevance to match outcome, external load measures associated with intensity appear to be an important factor among forwards. These results may be helpful for coaches and sport scientists when making decisions pertaining to training and competition strategies.
本研究的目的是调查基于比赛结果使用惯性运动传感器的特定冰上测量之间的差异,并确定球员在三个比赛时段的运动变化。在精英女子冰球运动员一个赛季的比赛期间收集了数据(N = 20)。对每个滑冰位置进行双因素混合效应方差分析,以研究比赛结果的差异以及比赛过程中外部负荷测量的差异。对于比赛结果,前锋在爆发力比率(p = 0.02,效应量ES = 0.26)和高力量步幅百分比(p = 0.04,效应量ES = 0.50)方面存在微小差异。当观察比赛的三个时段时,发现前锋在滑冰负荷(p = 0.01,效应量ES = 0.75)、爆发性努力(p = 0.04,效应量ES = 0.63)和爆发力比率(p = 0.002,效应量ES = 0.87)方面存在中等差异,后卫在球员负荷(p = 0.01,效应量ES = 0.70)、爆发性努力(p = 0.04,效应量ES = 0.63)和爆发力比率(p = 0.01,效应量ES = 0.70)方面存在中等差异。在研究与比赛结果的相关性时,与强度相关的外部负荷测量似乎是前锋中的一个重要因素。这些结果可能有助于教练和运动科学家在制定训练和比赛策略时做出决策。
