Objective This study aimed to analyze and compare the athlete's center of mass(COM)veloci-ty,COM height,ground reaction force(GRF),and lower limb joint moment of different levels of athletes during pole vault run-up and takeoff,so as to explore the technical characteristics of the transition between run-up and takeoff,which provides reference and help for the training and competition of pole vault.Methods A large-scale three-dimensional(3D)motion capture system(200 Hz)and three force plat-forms(2 000 Hz)were used to collect the kinematics and ground reaction force data of male elite pole vaulters,and five first-class athletes,four master athletes and three international master athletes were ana-lyzed.Mann-Whitney U test was utilized for biomechanical parameters between every two groups within in-ternational master athletes,master athletes,and first-class athletes.Wilcoxon signed ranks test was used between every two corresponding biomechanical parameters of the second-to-last step,the last step,and takeoff.Results The athletes'COM velocity,COM height,GRF,and lower limb joint moment showed signif-icant differences between the different level groups of pole vaulters,and the biomechanical parameters of the second-to-last step,the last step,and the takeoff also displayed significant differences.Conclusion Based on the data of this study,the male pole vaulters showed biomechanical characteristics that varied with their levels.The COM velocity and GRF of the international master athletes indicate their higher sports competence.The differences between the biomechanical parameters of the second-to-last step,the last step,and takeoff,including COM velocity,COM height and GRF,might display the technical charac-teristics of pole vault movement transition,which indicate the kinematic and kinetic transition characteris-tics of pole vault from run-up to takeoff.
