Pole vaulting has progressed rapidly in terms of improved mechanical properties and better appearance by using poles made of flexible fiberglass material. Competitive pole vaulting requires specific characteristics that promote higher jumps. Analysis of the dynamics of pole vaulting basically requires a thorough consideration with the aim of having a high flexibility of the pole and all joint torque actions of the body. In this research, simulation analysis to optimize the joint torque was done by using Genetic Algorithm. The system consists of a combination of a flexible pole and several links (vaulter). The vaulter was expressed by the three-dimensional model including twisting the waist. In the present genetic algorithm, the control parameters were the joint torque, and the evaluation function was the height. We defined the two types height of evaluation function, G-type and L-type, and the difference between two types was analyzed. As a result of optimizing the torque, the motion which avoids a cross bar appeared in L-type evaluation function.
