ABSTRACT: This study analyzed the kinematic parameters of the triple jump in male athletes from Zhejiang Province’s athletics team, using three-dimensional photography and the SIMI Motion 10.0 system. Key findings were: 1) Zhejiang Province’s male triple jump athletes had an average stride length of 2.05 ± 0.15 m for the penultimate step and 2.14 ± 0.14 m for the last step in the approach run, with a 0.09 m difference. The penultimate step’s center of mass averaged 8.32 ± 0.20 m/s in velocity, while the last step and take-off moment averaged 8.12 ± 0.25 m/s and 7.95 ± 0.14 m/s, respectively. 2) Significant correlations existed between kinematic parameters (landing instant velocity, take-off instant velocity, take-off instant vertical velocity) and triple jump performance across all phases. The strongest correlation was found between landing instant horizontal average velocity during the bound phase and athletes’ triple jump performance (γ = 0.97, P
