The contribution of some kinematic variables for the starting stage and their relationship to the achievement of the men's 100-meter sprint

Abstract

The study aimed to identify the most important kinematic variables of the launch phase. The researchers used the descriptive approach using the survey method and correlations to suit the nature of the problem to be studied. The researchers identified the research community as track and field runners for the 100m event in Iraq for the men's category for the 2024 sports season, numbering (16) runners. (6) runners were selected from Maysan Governorate as a sample for the research, thus forming a percentage of (37.5%) of the research community. The most important conclusions reached by the researchers are as follows: All study variables achieved positive contribution rates with achievement, and the push angle (rise) during the launch phase achieved the highest contribution rate to the speed of completing 100m. The most important recommendations were to emphasize the importance of applying biomechanical principles during the education and training of all age groups and all technical stages of the 100m event, and to conduct periodic tests and kinetic analysis to monitor the level of development in the technical and mechanical aspects and discover the defect to address it.
