The objective of this study was to develop the simulation model of the kick-start to determine the horizontaltake-off velocity on swimming. The human whole-body was modeled as a linked rigid-body segments tosimulate kick-start. This model simulates the kick-start motion using numerical integral. The cross-correlationcoefficient and the mean value of root mean squared error between the lower limb joint angles of simulationdata and actual data were determined to identify whether the simulation model could produce the kick-startmotion. In the horizontal take-off velocity, 0.05 m/s difference was found between the simulation data andactual data. The cross-correlation coefficient of lower limb joint angles between the simulation data and actualdata were larger than 0.76. Moreover, the mean value of root mean squared error of lower limb joint angleswere found 0.15-0.37 rad between simulation data and actual data. Therefore, developed simulation model ofkick-start on swimming can be used for studies which these errors have little effect for main findings.
