Abstract:	The purpose of this study is to use the displacement, velocity, and acceleration of body center of mass when performing the standing vertical jump from the force plate as a criterion to compare the errors of videotape when using different body segment parameters. Eighteen healthy male academics were served as the subjects for this study. A Kistler force plate (600Hz) and a Peak Performance high speed camera (120Hz) were synchro-nized to collect the subject performing the standing vertical jump. The vertical ground reaction forces and subject mass were used to calculate kinematical variables for the body center of mass during the vertical jumping. It was used as a criterion to compare the results of the body center of mss calculated from the videotape by using different methods of body segment parameters. Those methods including Dempster, Clauser, Zatziorsky & Seluyanov, Hu, Hanavan, Matsui, and Wang studies. The results showed the average standard error of estimate for displacement, velocity, and acceleration during action phase were 0.029 ± 0.009m, 0.164 ± 0.040m/s, 2.369 ± 0.527m/s2 respectively. During the flight phase, the average standard error of estimate for displacement, velocity, and acceleration were 0.041 ± 0.016m, 0.187 ± 0.061m/s, 0.897 ± 0.263m/s2 respectively. This study also indicated the error of kinematical variables in the body center of mass by Zatziorsky & Seluyanov, Hu, and Hanavan model were lower significantly than the other body segment parameters.The purpose of this study is to use the displacement, velocity, and acceleration of body center of mass when performing the standing vertical jump from the force plate as a criterion to compare the errors of videotape when using different body segment parameters.
