プロサッカーの試合でのプレー状況とプレーエリアで区分したフィールドプレーヤーの表面積の解析

抄録

Playing positions play an important role in football. Players are positioned closely during defense and widely during attack. Previous investigation has demonstrated that the surface area of the field players (SA) depends on the playing situation (PS), such as attack or defense. We hypothesize that SA is also related with the playing area (PA). The present investigation examined the influence of PS and PA on SA in a professional football match. We used 10 Hz GNSS units to monitor the ten field players in the first half of the ten official matches of second-division Japanese Professional Football League. PS was evaluated as attack or defense, while PA was divided into three areas based on the centroid position. The 2-way ANOVA test showed significant interaction of PS and PA with SA (p<0.001). The significant difference in SA between PS’s depended on PA and was limited to the first and second tertile from the players’ own goal area. Thus, the investigation suggests that SA depends not only on PS but also on PA.
