The purpose of this study was to develop a method for measuring the forces exerted by the individual hands during a pole-vaulting motion via the use of an instrumented pole. Thirty-two strain gauges, specialised for Fiber Reinforced Plastic (FRP), were attached to the pole. A quasi-static calibration of the strain gauges was conducted under a large pole-deformation condition. Two miniature wireless strain amplifier systems were used to record output signals from the strain gauges. The estimated hand forces and moments passed through an extended Kalman filter matched well with those calculated from the pole tip (plug) forces obtained with a force plate situated below the pole vault box. From these results, use of this instrumented pole would make it possible to estimate the forces exerted by the individual hands during the pole-vaulting motion, even without a force plate situated below the box.
