バスケットボールコーチングのためのドライブ動作の解析・評価

抄録

Drive motion, dribbling past the facing defender is one of the most basic offensive motion in basketball. Some previous works have mentioned the important body parts for coaching drive motion as shoulder or, hand. However, they have never mentioned time series relationship between them, for example, the timing each body part start to move. Therefore, the purpose of this study is to reveal the time series relationship between body parts for drive motion. We first measured the drive motion of 6 subject divided into two groups; advanced and intermediate using motion capture (Vicon, Oxford, UK) to get the velocity data of both feet, shoulders, hands, and center of mass. Then, using the measurement data, we conducted Discrete Fourier Transformation and Principal Component Analysis in the frequency domain for each subject. From the result of the time series analysis, we could find the common pattern between the use of left foot, left shoulder, and right foot for all subjects. Also, we could find a difference in the use of the right foot and right foot between the two groups.
