ABSTRACT:
Sport has become a great address for the advancement and progress of nations, and it is the civilizational key with which other peoples communicate. And the practice of sport has become the field in which many specialized scientists compete to develop their research and rise to a global level befitting the level of their countries. And that the advanced mathematical achievement and the advanced technical performance of the four quadrants did not happen as a result of coincidence or a stroke of luck but rather as a result of hard work, good numbers, and the optimal investment of the various natural sciences related to the proper application of scientific principles and foundations based on biomechanics. The importance of the research comes through identifying the relationship of some bio-kinematic variables and their relationship to the level of achievement in the snatch lift for the Iraqi champions for the applicants. The horizontal line affects the trajectory of the weight movement. The researcher used the descriptive method in the style of correlational relations to fit the research problem, where the research sample consisted of (5) lifters deliberately chosen by the researcher from the Iraqi heroes for applicants weighing (85) kg for the year 2022. The researcher also used a video camera, as it was placed at a distance of (5:50) m from the right side of the quadrant, the height of the imaging lens was (1.50) m from the level of the lifting drum, and the speed of the video camera was (25) images/sec. The variables of deviations of the research sample were extracted from the trajectory of the movement of the weight for the stages of the snatch lift. After the completion of the imaging process, the use of appropriate statistical treatments to reach the results, after which the results were presented, analyzed and discussed. The researcher reached the most important conclusion that adopting numerical values in calculating distances and deviations is more appropriate among the individuals of one sample. The results showed significant correlations in the amount of movement during the three stages of the research sample. As for the recommendations, the most important of them is emphasizing the presentation of recorded films for world championships to increase understanding of the performance method (technique), the necessity of training on the line of technical performance during the performance of the snatch by emphasizing the follow-up of error correction during the daily training units.
