Abstract–This study examines the performance of Mongolian junior athletes executing the “Straddle jump to push up” element through two distinct preparatory techniques: initiating from a preliminary jump (Group A, n=7) and taking a 2-3 step approach (Group B, n=5). The aim is to determine which technique enables athletes to achieve a greater vertical center of gravity (CG) height at various stages of the movement. The “Straddle jump to push up” was segmented into six technical components (E1-E6) for analysis. Participants, aged 13±1 (N=12), were evaluated in the biomechanics laboratory at Chungnam University, South Korea, using a 100-frame-per-second speed camera (Motion Master), control space meter, and the Kwon 3D XP software. Biomechanical study of jumping performance of athletes allows to detect errors. Findings reveal that the CG of Group A athletes was consistently higher than that of Group B from E1 through E4, the average value was 1.11 cm at E4, the peak component. These results suggest that initiating the “Straddle jump to push up” from a preliminary jump results in a higher CG elevation.
