The aim of this study was to describe the activity profile of top-class female soccer referees during competition and to relate it to the position of the ball. Ten matches from the Fédération Internationale de Football Association (FIFA) under-20 female World Championships held in Russia in 2006 were filmed and the kinematical parameters of the female referees (n=10) and the ball were determined using a two-dimensional photogrammetric video system based on direct linear transformation (DLT) algorithms. Total distance covered during a match was 10 km, of which 1.3 km represented high-intensity activities (>13 km/h). The referees' highest mobility was achieved in the initial 15 min of the match, covering greater distance and performing more intense exercise (P<0.01) than in the final 15-min of the game. Mean distance from the referee to the ball was 19.5+/-2.4m, with no significant differences between 15 min match periods. The results of this study show that: (1) the physical demands placed on top-class female referees are much like those experienced during male moderate-standard refereeing and (2) the referees were able to maintain the distance from the ball throughout the match.
本研究的目的是描述顶级女子足球裁判员在比赛中的活动情况,并将其与球的位置联系起来。使用基于直接线性变换(DLT)算法的二维摄影测量视频系统对 2006 年在俄罗斯举行的国际足球联合会(FIFA)20 岁以下女子世界杯的 10 场比赛进行了拍摄,并确定了女子裁判员(n=10)和球的运动学参数。比赛中裁判员的总跑动距离为 10 公里,其中 1.3 公里代表高强度活动(>13km/h)。裁判员在比赛开始的 15 分钟内移动性最强,覆盖的距离更大,运动强度更高(P<0.01),比比赛最后 15 分钟更高。裁判员到球的平均距离为 19.5+/-2.4m,在 15 分钟的比赛期间没有显著差异。本研究结果表明:(1)顶级女子裁判员所面临的身体要求与男性中等标准裁判员相似;(2)裁判员能够在整个比赛中保持与球的距离。
