Most studies on pole-vaulting focus on energy transfer data but do not take into account all the actions exerted on the pole. Starting from experimental measurements, this study presents a three-dimensional mechanical model allowing the determination of the pole-vaulter's actions on the pole. The force and the moment exerted on the pole by the pole-vaulter during the last stride before take-off and during jump stage have been calculated. Then, a comparative study is carried out on two pole-vaulters having comparable morphologies and performing with the same pole, and points out the influence on performance of the moment applied to the pole.
La plupart des publications relatives au saut à la perche considèrent des transferts d'énergie mais ne prennent pas en compte l'ensemble des actions exercées sur la perche. Cette Note propose un modèle mécanique tridimensionnel permettant à partir de mesures expérimentales de déterminer les actions de l'athlète sur la perche. L'effort et le moment exercés par l'athlète au cours du dernier appui précédant le décollage et au cours de la phase de saut ensuite, ont été calculés. Une analyse comparative, effectuée pour deux athlètes aux morphologies voisines, utilisant la même perche, souligne l'influence sur la performance du perchiste du moment appliqué sur la perche.
