Abstract

The purpose of this study was to investigate the effect of bat diameter on the batted ball characteristics in baseball. A custom-made bat swing machine swung bat horizontally and hit a ball floating in the air using wind pressure. Three bats of different diameter (6.30 cm, 5.73 cm, and 5.32 cm) were used with 30 trials per bat. Three high-speed video cameras were used to record the movements of the bat and ball near the impact and compared the batted ball characteristics. As a result, bat diameter did not appear to have a significant effect on batted balls.
