The aim of this study was to estimate the pole deformation by using an instrumented pole measuring exerted force by each hand in pole vaulting. Ten sets of strain gauges, two of them for measurements of axial force along the pole and rest of them for bending moments, attached on the pole. The pole was modeled as a series of 11 rigid segments connecting their adjacent segments via virtual joints with rotational spring. The stiffness of the individual spring component was identified from the pole loading test. One male pole vaulter participated in this experiment. A motion capture system was used to measure the 3D coordinate data of 47 and 24 reflective markers attached to the whole-body and the pole, respectively. The deformation of pole was estimated from the force and moment measured by instrumented pole, and the stiffness of the pole. Estimation of the pole deformation was compared with the measured of that.
