Pole vaulting is an event encompassing a multitude of variables. With so many moving parts, there is a challenge to determine the impact of the practitioner's manipulation. Previous researchers have used the full spectrum of tools to evaluate the pole vault: kinematics, kinetics, energetics, and simulations. Although work has been done to expand the knowledge and impact of variables in the pole vault, there is minimal reporting of the pole’s 3D movement during the pole vault. In this study, we evaluated the 3D movement of the pole and its impact on performance. The mid grips of fourteen collegiate and post-collegiate pole vaulters were tracked during a short approach pole vault (8 steps – 12 steps) during a 2-day experiment (day 1 familiarization, day 2 testing). Kinematic evaluations were performed on the pole vault pole’s mid grip to evaluate the progression of the pole, mid grip velocities, and the rate of change in pole chord length. Concerning the midline of the plant box, the mid grip’s medial-lateral position value at Max Bend had a strong correlation to the medial-lateral position value at Complete Recoil (r = .822 p <.001). Within the top performances of the men and women, a moderate positive correlation was determined between Peak Recoil vertical velocities of the mid grip and Maximum Clearance Height (r = .585, p = .028), Push Height (r = .580, p = .03), COH Maximum Height (r = .555, p = .039). Within the women participants, a strong positive correlation was determined between medial-lateral mid grip velocities at Peak Recoil and Maximum Clearance Height (r = .799, p < .001), Push Height (r = .623, p < .001), COH Maximum Height (r = .888, p < .001), COH Push Height (r = .866, p < .001). Within all participants, there were moderate negative relationships between the rate of change in pole chord length from Pole Plant to Max Bend and the Maximum Clearance Height (r = -.544, p < .001), Push Height (r = -.555, p <.001), COH Maximum Height (r = -.563, p < .001), and COH Push (r = -.589, p < .001). Within all participants, there was a moderate positive correlation between the rate of change in chord length from Max Bend to Peak Recoil to maximum clearance height (r = .575, p < .001), push (r = .505, p < .001), COH max height (r = .640, p < .001), and COH push (r = .652, p < .001). Additionally, within all participants, the rate of change in pole chord length from Pole Plant to Max Bend had a moderate negative correlation to the rate of change in pole chord length from Max Bend to Peak Recoil (r = -.684, p < .001). Based on our findings, tracking of the mid grip’s kinematics could be an advantageous method for measuring development in the pole vault. Specifically, this research emphasizes the benefits of some medial-lateral pole deflection while balancing the extent of medial-lateral pole deviation. Additionally, the research highlighted the benefits of increased vertical mid grip velocities and highlighted the positive relationship that compressing the pole at faster rates has on pole vault performance.
