摘要

摘要目的:考察一系列情境因素对国际七人制橄榄球比赛中身体和技术表现的独立影响。方法:在一个比赛赛季中,从一支球队的20名职业七人制橄榄球运动员中收集数据。使用可穿戴微技术设备测量活动概况,并使用匹配视频分析收集技术性能指标。进行了主成分分析,将物理和技术比赛表现变量的维度降低为包含每个变量不同信息的单一指标值。然后构建线性混合模型来检验外部情境因素对身体和技术指标得分的集体影响。结果:失分增加、比赛结果获胜和天气更有利都对身体表现因素产生了积极影响,而所有其他情境因素都没有显著改善模型的拟合度。技术表现因子值随着比赛持续时间的延长而增加,当与排名较高的对手比赛时则会减少。结论:这些发现表明,赢得比赛、丢更多分和更有利的天气条件与身体表现的提高有关;而技术表现随着比赛持续时间的延长和与排名较低的对手比赛而提高。

Situational factors affecting rugby sevens match performance
ABSTRACT Purpose: To examine the independent influence of a range of situational factors on physical and technical match performance during international rugby sevens matches. Methods: Data was collected from 20 professional rugby sevens players from one team across one competitive season. Activity profiles were measured using wearable microtechnology devices, and technical performance measures were collected using match video analysis. A principal components analysis was conducted to reduce the dimensionality of the physical and technical match performance variables into single index values incorporating each variable’s distinct information. Linear mixed models were then constructed to examine the collective influence of external contextual factors on physical and technical index scores. Results: Increased points conceded, a winning match outcome, and more favourable weather all had positive impacts on the Physical Performance Factor, with all other situational factors examined not contributing to a significantly better model fit. Technical Performance Factor values were shown to increase with longer match involvement durations and decrease when playing against higher ranked opponents. Conclusions: These findings show that winning the match, conceding more points, and more favourable weather conditions are associated with increased physical performance; whilst technical performance improved with longer playing durations and playing lower ranked opponents.
