Abstract：
Using an expert consensus-based approach, a netball video analysis consensus (NVAC) group of researchers and practitioners was formed to develop a video analysis framework of descriptors and definitions of physical, technical and contextual aspects for netball research. The framework aims to improve the consistency of language used within netball investigations. It also aims to guide injury mechanism reporting and identification of injury risk factors. The development of the framework involved a systematic review of the literature and a Delphi process. In conjunction with commercially used descriptors and definitions, 19 studies were used to create the initial framework of key descriptors and definitions in netball. In a two round Delphi method consensus, each expert rated their level of agreement with each of the descriptors and associated definition on a 5-point Likert scale (1-strongly disagree; 2-somewhat disagree; 3-neither agree nor disagree; 4-somewhat agree; 5-strongly agree). The median (IQR) rating of agreement was 5.0 (0.0), 5.0 (0.0) and 5.0 (0.0) for physical, technical and contextual aspects, respectively. The NVAC group recommends usage of the framework when conducting video analysis research in netball. The use of descriptors and definitions will be determined by the nature of the work and can be combined to incorporate further movements and actions used in netball. The framework can be linked with additional data, such as injury surveillance and microtechnology data.
摘要：
使用基于专家共识的方法，形成了由研究人员和从业者组成的无挡板篮球视频分析共识（NVAC）小组，以开发物理，无挡板篮球研究的技术和背景方面。该框架旨在提高无挡板篮球调查中使用的语言的一致性。它还旨在指导伤害机制报告和伤害风险因素的识别。该框架的开发涉及对文献的系统回顾和Delphi过程。结合商业使用的描述符和定义，19项研究被用来创建无挡板球中关键描述符和定义的初始框架。在两轮德尔菲法共识中，每位专家以5点Likert量表(1-强烈不同意;2-有点不同意;3-既不同意也不同意;4-有点同意;5-强烈同意)对每个描述符和相关定义的一致性水平进行评分.协议的中位数(IQR)评级为5.0(0.0)，5.0（0.0）和5.0（0.0）用于物理，技术和上下文方面，分别。NVAC小组建议在无挡板篮球中进行视频分析研究时使用该框架。描述符和定义的使用将取决于工作的性质，并且可以结合起来以纳入无挡板球中使用的进一步运动和动作。该框架可以与其他数据链接，如伤害监测和微观技术数据。
