Consistent maximum ball velocity is an important factor for more successful pitching. While The focus of studies have analyzed pitching mechanics on upper limbs, little investigation has been given to the motion of trunk and lower limbs. The purpose of this study was to present difference of lower limb and trunk kinematic variable according to plane when pitched ball velocity increase in the same subject in two pitched ball velocity such as 110km/h, 120km/h. The subjects of this study were the nine right-handed pitcher who belonged to professional, university and high school. 3D cinematograph which pictured subjects was analyzed by LabVIEW 6i(Johnson, G.W., 2000) and SPSS 10.0 to compare three kinematic variables by plane. The results can be summarized as follows: In temporal variable, Maximum lead knee flexion and extension occurred later according to ball velocity increased. Trunk tilting angle(p=.047), lead knee angle(p=.034) had statistically significant difference in the time when lead foot contact and ball release. When Instance of shoulder`s maximal external rotation, kinematic variables had statistically significant difference in trunk tilting angle, knee angle and pelvis rotation angle(p=.042).
