The research aimed: to identify the effect of specific exercises on some of the kinetic characteristics of the step and the stages of performance (hopscotch - step - jump) and the digital level in the triple jump for the sample under study. The researcher used: the experimental approach with pre and post measurement for one experimental group, and the descriptive approach using mechanical analysis based on the two-dimensional (2D) video imaging method and kinetic analysis using the Simi motion program, due to their suitability to the nature of the study,The research sample included: triple jump players from clubs (Al Rowad Club in the 10th of Ramadan - Kafr Saqr Youth Center - Kafr Saqr Club) represented by (6) players under 18 years of age, and (2) of them were excluded to conduct the exploratory study, thus becoming the basic research sample becomes (4) players with (8) attempts. Among the most important results: The highest biomechanical indicators of improvement and impact were the vertical velocity index of the general center of gravity of the body during all selected performance moments in the triple jump (6.91 %). The qualitative exercises had a positive and statistically significant effect on the biomechanical indicators, the motor characteristics, the performance stages of the triple jump, and the digital level. The researcher recommended: the use of biomechanical analysis as a measuring tool (correction) to know the strengths and strengthen them and the weaknesses and their treatment for the triple jump players to develop different training programs and in proportion to the players. Directing and taking care of it during training to raise the performance level of the triple jumpers and improve the stages of performance and the digital level.
