| Research Abstract |
The present study focused on the characteristics of the bat used by batters in baseball and examined the acceleration applied to a bat and how the mass and position of the COG affect swing. The swing of each batter was reproducible and unique, their swing movement conforming to a fixed form for each batter. For each batter, the most suitable bat properties to maximize angular momentum through changes in angular momentum applied to the bat according to changes in the bat were investigated.
