The purpose of this study was to compare the kinematic the pitching motion between Taiwanese, Japanese, Cuban, and American collegeate pitchers (21.9±1y, 1.76±3.8m, 76.6±7.9kg). Kinematic data were analyzed for 10 Taiwanese baseball pitchers, and compared with advanced research by Shimada et al. (2012), Takahashi et al. (2005), Escamilla et al. (2001), and Fleisig et al.(1999). Taiwanese pitchers showed larger peak pelvis rotation angular velocity (Taiwanese: 844.1±215.5 deg/s, Others: 720.2±174.44 deg/s). and smaller rotation angle at release(REL) of Taiwanese pitchers (T: -88.6 ± 9.9 deg) was larger than that of foreign baseball pitchers (O: -92.9±9.3 deg). Due to the kinetic chain, Taiwanese pitchers were unable to transfer the kinetic energy from the lower body to the upper body, and then, they couldn't increase ball velocity.
