THE STUDY OF BATTING PERFORMANCE OF DIFFERENT MATERIAL BAT
Keywords: batting performance, batted-ball velocity
AbstractThe purpose of this study was to compare the velocity of sweet spot and batted-ball velocity during swing different material bat. Three collegiate baseball players randomly swung five different material bats. The high-speed video (2000 fps) was placed 7 meter above subject to capture swing image. The swing velocities of sweet spot before impact, after impact and batted-ball velocity were calculated. The results reveal that batted-ball velocity of bamboo bat and compound bat were between alloy bat and wood bat. There are significant correlations among bat velocity before impact and batted-ball velocity. We suggest that the bamboo or synthetic material of wood and bamboo were suitable to produce baseball bat. Moreover, it is very economy and safer than alloy bat.
