C-11 Finite element simulation of head injury accidents in sports : Examples of Judo and Americal football

Abstract

In this study, Judo and American Football (AF) are spotlighted as typical physical contact sports that concussion or subdural hematoma could happen during a play. In Judo, "waza" to cause a risk to hit a head on a tatami were performed by Judo players and recorded by VICON system and the motions were reconstructed by MADYMO by using VICON data and kinetic data and hit part were generated. In Americal football, the moment of concussion was reconstructed by MADYMO by observing the accident data in real play recorded on a video and kinetic data and hit pat were generated. In both cases the strain and stress of the brain tissue were calculated in detail by the FE human head model and injury risk was predicted, respectively.
