After reviewing the training that was prepared by the trainers, it was found that they were of a traditional pattern that did not improve the body's muscular activity, through which the work of the muscles could be improved and the ideal achievement could be achieved. Through what was mentioned, the researcher will prepare trainings specific to the special aerobic endurance capabilities according to the effect of the targeted time for the event in improving some biomechanical indicators and endurance for the advanced category competing players, which is one of the scientific solutions in training that positively affects achieving the highest levels for players in the 1500-meter running race. The aim of the research is to identify the biokinematic indicators according to the effect of the target time and the achievement of a 1500-meter running event for advanced athletes. The research method the researcher used the experimental method by designing two equivalent groups with a pre-test and post-test in order to suit the research problem. The research community was chosen, which is the players of the elite national team for the 1500-meter running event for the advanced season 2022-2023 AD, numbering (12) players who were deliberately selected from the research community and represented 100% of this community. The researcher divided them randomly by lottery into two equal groups with (6) players for each group, one of which is the experimental group and the other the control group. This is to suit the research problem. The researcher concluded that training using running at the target time and speed and in a high-intensity method led to the development of biokinematic indicators (frequency and length of steps) in all stages of technical performance in the 1500-meter race. The researcher recommends the necessity of working on linking the biomechanical indicators related to the players' steps (step length and frequency) with the physiological indicators when training the players in the 1500-meter running event.
