摘要

橄榄球联盟铲球视频分析研究通常使用来自教练线索的技术标准或来自橄榄球联盟的铲球变量。因此,内容的有效性和相关性可能会受到质疑。因此,需要一个视频分析框架,为橄榄球联盟建立适当的变量。本研究旨在采用5个阶段的过程来建立橄榄球联盟铲球的视频分析框架,该框架内容有效,相关且可靠。5个阶段的过程包括:1)创建视频分析框架草案,利用现有的橄榄球铲球研究;2)招募和批评专家组;3)改进框架以建立内容效度;4)响应过程效度任务和专家组内部的一致性;5)使用Kappa统计进行内部和相互信度测试。商定的框架包括六个阶段,包括;铲球事件,防守起点,接触前,初次接触,接触后和持球。在确定的阶段内,建立了63个变量。内部和内部的可靠性测试结果在所有阶段都非常一致。视频分析框架可用于橄榄球联盟的铲球研究,对复杂的铲球事件进行分类,例如受伤或最佳铲球,从而提高球员的福利和表现。将该框架应用于未来的橄榄球联盟研究将增加研究结果的连贯性和有用性。

A video analysis framework for the rugby league tackle
ABSTRACT Rugby league tackle video analysis research typically uses technical criteria from coaching cues or tackle variables from rugby union. As such, content validity and relevance could be questioned. A video analysis framework that establishes appropriate variables for rugby league is therefore required. The study aimed to adopt a 5-stage process to establish a video analysis framework for the rugby league tackle, which was content valid, relevant and reliable. The 5-stage process included 1) creation of draft video analysis framework, using available rugby tackle research, 2) expert group recruitment and critique, 3) refinement of framework to establish content validity, 4) response process validity task and agreement within expert group, 5) intra- and inter-reliability testing using Kappa statistics. The agreed framework comprised six phases including; tackle event, defensive start point, pre-contact, initial contact, post-contact and play-the-ball. Within the identified phases, 63 variables were established. The intra- and inter-reliability testing resulted in strong agreement within all phases. The video analysis framework can be used in rugby league tackle research, categorising complex tackle events, such as injurious or optimal tackles, improving both player welfare and performance. The application of the framework to future rugby league research will increase coherence and usefulness of research findings.
