目的：本研究目的為探討慢速壘球打擊在不同好球板位置運動學的差異。方法：受試者為12名大專慢速壘球系隊男性右打者選手，以Vicon動作分析系統收集好球板前、中間和後位置的慢速壘球打擊之上下肢和軀幹角度變化，使用重複量數單因子變異數分析比較不同好球板位置的運動學差異。結果：本研究結果發現好球板中間位置打擊有較大的球棒速度與球速。和中間位置相比，好球板前位置有較長的揮棒時間與較大的步幅長，上軀幹和骨盆在前腳離地與著地時有較小的向後旋轉角度，在擊球瞬間有較大的向前旋轉角度，左及右肘關節在擊球瞬間有較小的屈曲角度，在手開始向前及擊球瞬間，有較大的右膝屈曲角度。另外，好球板後位置在前腳離地與著地時有較大的上軀幹和骨盆的向後旋轉角度，在擊球瞬間有較小的上軀幹和骨盆的向前旋轉角度，且有較大的左肘屈曲角度，在揮棒4個時期有較小的右膝關節屈曲角度。結論：慢速壘球打者在面對好球板不同位置時會有打擊運動學的差異，本研究結果可以提供慢速壘球教練與打者瞭解在不同好球板位置時打擊動作的差異。

Purpose：The purpose of this study was to investigate the kinematics of different strike plate areas in slow pitch softball hitting. Methods: Twelve right-handed college slow pitch hitters participated in this study. Vicon motion analysis system was used to measure the kinematics of slow pitch softball hitting. One-way ANOVA with repeated measure was used to compare the kinematic differences between different strike plate areas. Results: A faster ball velocity and bat velocity were found in middle strike plate area. Compared to middle strike plate area, anterior strike plate area showed a longer hitting time, greater stride length, lesser backward rotation on upper torso and pelvis at foot-off and foot-on, lesser elbow flexion angle at impact, greater right knee flexion angle at hands started to move forward and impact. Moreover, posterior strike plate area showed a greater backward rotation on upper torso and pelvis at foot-off and foot-on, lesser forward rotation on upper torso and pelvis at impact, greater left elbow flexion angle, and lesser right knee flexion angle. Conclusion: Kinematic differences between different strike plate areas were found in college slow pitch softball hitters. The information could be provided for the coaches and hitters to better understand the effect of different strike plate areas on hitting kinematics.
