Abstract EN

The problem of the research lies in the lack of knowledge of many of those in charge of the training process in Iraq on the biomechanical and physical laws that control the technical performance of this activity, as many of them were satisfied with observation without resorting to the kinetic analysis process, which is an essential part of biomechanics, which analyzes movement analysis Biomechanically and in all its departments, as well as what is characterized by this effectiveness of difficulty in performance and weakness in the training process, and the objectives of the research are to identify the following: 1-Identifying the values of some genomic variables for the stages of advancement (hopscotch - step - leap) for the research sample.2- Identifying the relationship between the genomic variables of the stages of advancement (hopscotch - step - leap) and the level of achievement of each stage and the overall achievement of the triple jump.

The researcher assumed: 1- There is a significant correlation between the level of achievement of each stage and the overall achievement and some genomic variables for the stages of advancement (hopscotch - step - leap) for the research sample.

The experiment was carried out by filming with (4) CASIO video cameras), and the researcher took into account that the locations of the video cameras should be within the field of movement to be studied, and from the right side of the field of jumping.

It was taken into account that the axis of the lens is perpendicular to the level of the field of movement and at a height of (1) m from the ground for all cameras used in the experiment to cover the highest height reached by the jumper.

The data were treated statistically by using the SPSS program to extract the arithmetic mean, standard deviation, coefficient of variation and correlation coefficient.

The researcher concluded the following: - There is a significant correlation of the angular difference variable of the hopscotch stage with the total achievement of the triple jump, due to the small angle of the front pivot and the angle of the back pivot, which is a great helper factor in the continuity of speed.

- It was found that there is a significant correlation for some genomic variables of the hopscotch stage (knee joint angle, front pivot angle, rear pivot angle, flight angle, height center of gravity of the body mass) for the ascent of the hopscotch stage with the overall achievement of the triple jump.

- It was shown that there is a correlation for some genomic variables for the step stage (knee joint angle, trunk inclination angle in collision, body inclination angle in collision, knee joint angle in orption, trunk inclination angle in orption, height of center of gravity of body mass in orption, height of center of gravity of body mass Thrust, front pivot angle, rear pivot angle) with the overall achievement of the triple jump.
