In motion analysis, the optical method is often used, but non-optical method is not so. The purpose of this study was to attempt three-dimensional motion analysis using electromagnetic tracking device, which is one of the non-optical method. First we defined body coordinate systems by attaching sensors to each segment. Then we calculated joint angles by adapting the relative movement of two coordinate systems to joint motion. The angle of lumber, hip and knee was compared between two different kick motions. As a result, we could concisely obtain many kinds of joint angle, and these data clarified the difference in two motions. The present study suggests that this experimental method is useful to analyze body motion.
