To compare positional differences in the physical and technical demands of Australian Football League Women's (AFLW) match-play. A secondary aim was to examine the time course changes in activity profiles during AFLW match-play.
Longitudinal observational study.
Global positioning system data were collected from 26 players (6 positional groups) from the same club during seven AFLW matches. Absolute and relative physical performance data were categorised into total distance, high-speed running (>14.4kmh, HSR), very high-speed running (>18.0kmh, VHSR), and sprinting distance (>20.0kmh, Sprint). Technical performance data was obtained from a commercial statistics provider. A mixed model analysis was used to examine differences between positional groups and playing quarters.
Absolute measures of running performance did not differ between position groups. Relative total distance was moderately greater (ES=∼0.80, p<0.05) for midfielders, small backs and small forwards (125-128mmin) than tall backs and tall forwards (102-107mmin). Relative HSR distance was greater (ES=∼0.73) for midfielders and small backs (∼28mmin) than tall backs (17mmin). Analysis of technical performance indicators showed: midfielders and small forwards had the most inside 50s; tall backs had the highest number of rebound 50s; tall forwards scored more goals; while midfielders made more tackles (p<0.05). All relative running performance measures were reduced in the fourth quarter when compared to the first and second quarters (ES=0.32-0.77).
These data can be used as benchmarks for temporal analysis of AFLW match demands and assist in developing specific training strategies.
比较澳大利亚足球联赛女子组(AFLW)比赛中身体和技术需求的位置差异。次要目的是检查 AFLW 比赛中活动模式的时程变化。
纵向观察性研究。
从同一俱乐部的 26 名球员(6 个位置组)在 7 场 AFLW 比赛中收集全球定位系统数据。绝对和相对体能表现数据分为总距离、高速跑动(>14.4kmh,HSR)、超高高速跑动(>18.0kmh,VHSR)和冲刺距离(>20.0kmh,冲刺)。技术表现数据由商业统计提供商提供。使用混合模型分析来检查位置组和比赛季度之间的差异。
位置组之间的跑步表现的绝对测量值没有差异。中场球员、小后卫和小前锋的相对总距离(ES=∼0.80,p<0.05)较大(125-128min),而高大后卫和高大前锋(102-107min)较小。中场球员和小后卫的相对 HSR 距离(ES=∼0.73)较大(∼28min),高大后卫(17min)较小。对技术表现指标的分析表明:中场球员和小前锋有最多的 50 米内射门;高大后卫有最多的反弹 50 米射门;高大前锋进球更多;而中场球员的铲球次数更多(p<0.05)。与第一和第二季度相比,所有相对跑动表现指标在第四季度都有所下降(ES=0.32-0.77)。
这些数据可作为 AFLW 比赛需求的时间分析基准,并有助于制定特定的训练策略。
