22S サッカーのインフロントカーブキックに関する基礎研究

抄録

The purpose of this study is to assess the fundamental characteristics that cause a football to spin in an infront curve kick. The ball impact process of top view image was analyzed with a high speed video camera running at 4500 frames per second. The average foot velocity was 24.2 m/s and the average ball velocity was 27.1 m/s. The average revolution number on infront curve kick in this study was 7.8 r/s. The attacking angle between the face vector and the swing vector was observed in each trial. The average attacking angle between the face vector and the swing vector was 35.4 deg. It is considered that, in infront curve kick, the foot shape with the attacking angle between the face vector and the swing vector at impact generates the moment to spin the ball.
