B-32 剣道の素振りを含めた下肢の動作解析(ゴルフスイングほか)

抄録

In recent years, in research fields such as gait analysis, ergonomics and sport, video processing has been used. A high speed camera can observe a motion slowly. We can get an animation of a slow motion by taking a number of frames at the time of photography. A motion capture is also a technique to record the movement of a real person and object digitally. We visualize a movement of the kendo, and analysis a motion of the lower limbs during swing of an experiencer or a beginner. The measurement contents are velocity measurement of the tip of the shinai. Motion analysis of lower limbs and analysis of tendon motion by floor reaction force. There was difference in velocity of the tip of the shinai by a person with experience and an inexperienced person. In the motion analysis on lower limbs, it has been understood that power to step is five times larger than power to kick.
