Understanding the relative contribution of technical and tactical performance to match outcome in Australian Football

ABSTRACT

The aim of this study was to assess if tactical and technical performance indicators (PIs) could be used in combination to model match outcomes in Australian Football (AF). A database of 101 technical PIs and 14 tactical PIs from every match in the 2009–2016 Australian Football League (AFL) seasons was merged. Two outcome measures Win-loss and Score margin were used as dependent variables. The top 45 ranked technical and tactical PIs from a feature selection process were used to model match outcome using decision tree and Generalised Linear Models (GLMs). Of the top 45 selected features, this included seven tactical PIs. The Win-loss-based Decision tree model achieved a classification accuracy of 89.0% and GLM 93.2%. A Score margin-based GLM achieved a root mean squared error (RMSE) of 6.9 points. A combined approach to the classification of match outcomes provided no improvement in model accuracy compared with previous literature. However, this study has established the relative importance of technical and tactical measures of performance in relation to successful team performance in AF.     

Body composition differences by age and playing standard in male rugby union and rugby league: A systematic review and meta-analysis

ABSTRACT

This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts.

中国男篮后卫群体的弱势效应分析

目的:分析后卫群体对中国男子篮球队整体实力的影响,探讨提高后卫运动员能力的对策.方法:通过观看现场直播和比赛录像,采用数理统计、文献资料调研等研究方法,从定性和定量两方面,对男篮后卫群体的比赛能力进行分析.结果:在得分、助攻、抢断、失误、篮板5项指标上,男篮后卫群体有3项指标(得分、助攻、抢断)与世界强队优秀后卫的数据相比,差异具有显著性意义(P<0.05).据此,提出"空间-机会"观点,用于解释我国男篮后卫群体低得分、高失误、抢断少、助攻难的原因.结论:后卫群体的能力"短板",是影响中国队竞赛成绩的主要原因.建议:中国队应确立各位置均衡发展的指导思想,在坚持"快、准、灵"传统技术风格的基础上,着力解决破紧逼、体能、对抗和娴熟运用各项技术的综合能力.
