The contribution rate of some kinematic variables to the discus launch and their relationship to the achievement of discus throwers

Abstract

       The study aimed to identify the most important kinematic starting variables and also to identify the proportions of the contribution of some kinematic starting variables in the completion of disc throwing, And also identify the relationship of the ratios of the contribution of the most important variables of kinematic starting in the completion of throwing the disc, either the imposition of the study has imposed the researcher there is a significant correlation between some variables of starting kinematic and the achievement of the effectiveness of throwing the disc, The researcher used the descriptive approach in the survey method and correlation relations to suit it with the nature of the problem to be studied, and the researcher identified the research community of female athletes participating in the Iraqi Athletics Clubs and Institutions Championship for the women's category, which was held in November 2023, The number of participants was (13) participants representing the research community, and (10) of them were selected according to the level of achievement and the requirements of conducting the field research experiment, and they represented 76.92% of the research community, The most important conclusions concluded by the researcher that all variables of the study have achieved positive contribution rates with achievement, either the most important recommendations were attention to the technique of throwing, especially the variables of the launch because of its significant contribution to the achievement.
