Abstract
Biomechanics Cinematography data collection and analysis procedures were employed to compute the momentum of a pole vaulter throughout the performance. Simultaneously horizontal and vertical force components acting on the tip of the pole were measured in the vaulting box. Two phase-locked Photo Sonics cameras were used to record the vault and the analog force signal. The changes in momentum computed from the subject film were found to be within six percent ( 16 Ns ) of the concomitant impulses obtained from numerical integration of the force - time data.
