[Purpose] This study compared differences between groups to determine instructional factors for beginners, by focusing on the pelvic movement in the straight right punching motion. [Subjects] The two groups were those with experience (n=5,27.3±4.5 years old) and without experience (n=7,22.3±1.2 years old) of boxing. [Methods] We measured three straight right punching motions using a three-dimensional motion analysis system, and derived the pelvic rotation angle, pelvic angular velocity, and rotation time. Based on the maximum pelvic rotation angle, the results were divided into acceleration and restoration periods. Using the average values of each measurement in both periods we investigated, the significance of difference between the experienced and inexperienced groups. [Results] In both groups, a significant difference was found in the maximum pelvic rotation angle and the maximum pelvic angular velocity in the two periods, as well as the average pelvic rotation time in the restoration period. [Conclusion] When coaching beginners in boxing, the results suggest that there is a need to instruct carefully about going back to the original stance immediately.
