Kendo is a Japanese bamboo sword-fighting sport where protective armours are used. When you make a strike, you have to strongly step forward with the right foot after kicking the ground strongly with the left foot. For this action to be successful, muscular strength and lower limbs- muscle power is required. So far in the research of the Kendo competition, the measurement of floor reaction force which uses force plate was too much. However, the evaluation of power applied within the living body wasn't almost carried out. Therefore, in order to evaluate the power applied within the living body, we measured the locus and the floor reaction force of the stepping and the kicking action between amateurs and rank holders. In this research, from the measurements of the stepping and kicking movements, we directly measured the locus, angle of each joint, floor reaction force and floor reaction force moment, and from this data we evaluated the moment acting in each joint and the consumed energy acting each muscle.
