The purpose of this study is to analyze batting-related factors and the respective batting average. Subjects include 10 baseball players curently studing in K university in D city. The 10 players were divided into two groups; 5 from the High batter group, and 5 from the Low batter group for the purpose of this research. Video analysis was used for the research of bat speed and accuracy. In total, 120 videos were created and edited for analysis, and the batters were given orders to determine the type of ball thrown, and whether the ball was a strike or not. Results showed that in comparison of the bat speed of the High batter group and the Low batter group, the bat speed of the High batter group was statistically significantly higher (p<.05). In batting accuracy, the Low batter group showed significantly higher results (p<.01). The average batting showed statistically significant relations with the T-batting maximum velocity of batting (p<.05) and the T-batting average speed (p<.01), and the Free-batting average accuracy (p<.05). TMS regression intercept (β=739) and its changes showed significant influence at the 5% statistically significant level, and the explanation of the changes of batting average resulting from changes of TMS showed R2=.546, and therefore increased the predictability by 54.6%.
