抄録

The lower limb motion to maximize the ball velocity in water polo was solved by an optimizing simulation in the present study. The simplified simulation model for the throwing motion was developed in order to reduce the computation time. The right hand velocity was used for the evaluation instead of the ball velocity. The Particle Swarm Optimization was used for the optimizing algorithm. The objective function consisted of the right hand velocity and a penalty term regarding the hip joint torque and power. The design parameters were the hip flexion/extension angles of four time frames around the time of ball release. From the simulation results, it was found that the throwing motion to increase the ball velocity was accompanied by the right leg swinging back more and both legs moving ahead more. These motions induce the rotation of the upper half of the body forward. This rotation contributes to the ball velocity.
