Abstract
The purpose of this study was to comparion analysis of the moment of inertia in the major of korean dance and morden dance of lower extremity. The evaluation of the data is determained through MRI in accordance to its longitudinal axis. The images received through MRI are traced into each slice. The longitudinal moment of inertia, radius of Gyration and the segment mass are measured and its quantity is evaluated in relation to the body components. To achieve the purpose, 3 major of korean dance and 3 major of morden dance living subjects were filmed by General Electric Magna (0.5Tesla). The interval of MRI imagine of each segment was 1cm. The ratio of segment mass to the whole body and COG location of segment were calculated. Also, the moment of inertia and the ratio of radius of gyration of each segment were estimated from MRI imagine.
