The men's 100-meter sprint event is one of the most important events in athletics, and it requires high physical capabilities and special movement capabilities in addition to some physical specifications. biomechanical conditions. The importance of research is highlighted by the continuous interest in sports achievements and the continuation of the process of developing them, and the importance of kinetic analysis in revealing the most important weaknesses of runners, and the importance of achieving partial distances in the best possible time, which makes the difference in the fastest race for athletics events. The cognitive problem of the study centered on the question of the possibility of identifying the percentages of contribution of some partial distances to achievement, focusing on the weaknesses that the runner suffers from in achieving the ideal time for the required distance, and working on analyzing these particles and their applications in developing achievement. And to neglecting the use of motor analysis and identifying weaknesses with high accuracy, in addition to the lack of interest on the part of trainers in the characteristics of these values in order to program their training programs in order to achieve their goals as quickly as possible and with the least effort. The research aimed to identify the numerical values of the partial distances time (30, 60, 80) meters and the percentage of the contribution of these distances to the final achievement. The researchers used the descriptive approach in the style of correlational relations for its suitability to the nature of the problem of the study. The research community consisted of elite Iraqi 100-meter runners, numbering (10) runners. They took a comprehensive enumeration method. The test was conducted on the research sample in the Najaf International Stadium, in preparation for the Iraqi Clubs Championship, the second round. (10) were used. Analysis cameras type (CASIO FH13.5) at a speed of 120 frames per second, and the analysis was done with the analysis program (Kenova). After analyzing and discussing the results, the researchers concluded that there is a large contribution ratio between the time of a distance (30, 60) meters with completion, and there is no contribution ratio between the time of a distance (80 ) meter with achievement. In light of this, the researchers recommend conducting extensive studies for this effectiveness to diagnose weaknesses and strengths in technical performance, and pay attention to the biomechanical aspect and kinetic analysis.
