This paper proposes the new dynamic absorber using viscous and elastic materials (GEL) to prevent numbness in the hands when batting with a metal bat. First, in order to obtain data for designing the dynamic absorber, the vibration characteristic of GEL is examined experimentally because there is no information on the spring factor or damping factor of GEL. This dynamic absorber, which we propose in this research, is formed from an absorber mass and a selected optimum GEL. Therefore, this dynamic absorber is compact, light, and easily made. It can be mounted in the grip end of a metal bat. The effectiveness and usefulness of this device in reducing the numbness in the hands have been demonstrated experimentally and theoretically
