Abstract

In today’s baseball, a bunt is considered as an important tactic. Therefore the aim of this study was to define the kinematic characteristics of bunt comparing between experts and beginners. Five expert players and five healthy male students participated in this study. Subjects bunted 10 times. 3-D coordinate was determined by DLT METHOD. Using these variables, the variance of distance between the bat-head and forehead, and the variance of bat-angle were researched and analyzed by z-test (p<0.05). In the variables of the bat-angle no significant deference was recognized. In the variable of the distance between the bat-head and the forehead, a significant deference was recognized. Reliability of this data will increase by having an amateur baseball player and a professional baseball player perform the experiment that they performed this time.
