| Research Abstract |
The purpose of this study is analyzing a contact play of the rugby football and is the construction of the collision dynamics model. Therefore a micro inertial sensor was put on a real player, and the motion properties of practical skills (tackles and side steps) were measured. (1)position angle conversion, (2)electrical noise reduction and (3)span error (drift error) correction were applied to sensor signal. And the measurement for the real rugby player was repeated. In this study, it succeeded to measure motion of rugby player properties in the practical skill for several seconds. A crash force and the motion trace of the measurement result were compared with the real value (truth value), and a measurement was possible with probability of the approximately 50%.
