The development of the pole vaulting record is only improved by 1 centimeter over the last 25 years. Multiple studies show signs of different control strategies in elite pole vaulters, without pointing out what the cause of the differences is The aim of this research is to explore pole vaulting strategies by a control torque optimization. The optimization is performed for a simplified biomechanical model. The vaulter contains three segments: arms, a trunk including the head and legs. The joints are represented by torque actuators, located at the hands, shoulder joint and hip joint. The torque profile of each actuator is optimized. The optimization starts just after the pole is planted. It ends when the vaulter releases the pole. The pole length, pole stiffness, the vaulter’s length, the vaulter’s mass and the take-off angle are varied to discover the influence of these parameters on the control strategy. Three control strategies are found, as well as two power management strategies. Global trends are found. An increased pole stiffness, a decrease in length and mass of the athlete and a decreased take-off angle improved the performance. A possible optimal pole length is found.
