Abstract
This study reports on an exceptional approach to determine the appropriate length of a pole for pole vaulting by cutting off its lower end. The author, a female pole vaulter, presents a case study based on the results of jumping experiments conducted by Decathlete. The study reports on the process of cutting the pole based on the experiment results and the changes in the author’s jump performance using the cut pole. Based on subjective evaluations by Decathlete, a pole length cut of 0.10 m was deemed inappropriate. To obtain greater confidence in the results, objective changes in pole behavior, such as maximum pole curvature and pole angular velocity, were analyzed through video analysis. As a result, there was no change in the maximum pole curvature, but the pole angular velocity reached its highest value when the pole was cut by 0.10m. Two months after cutting the pole, the author’s jumping performance using the cut pole in an actual competition showed an increase in the clearance height from 0.30m to 0.50m.
