Outline of Final Research Achievements

In the rugby football game, the wearable inertia motion sensor are used for measurement of useful information data for strategy planning and coaching. In this study, we make the MATLAB code based on the inverse dynamics theory, and tried calculation of the joint torque of each human trunk part by inputting acceleration, angular velocity and geomagnetism data to be provided from inertia sensors. In the experiment, the measurement with the inertial sensor and a video shoot were carried out to attempt of the hitting action (The action that a player clashes with a dummy bag with a ball). As a result, we were able to obtain the qualitative information that was useful for skill training. Logical and qualitative data was provided about the joint torque of physical all parts for a coach to explain it to a player.
