The relationship between the variables of speed and launch angle of the implement in weight, overall length, and javelin throw performance for youth aged 15-16 years.

Abstract

The research included a study of the level of performance in javelin throwing and the relationship of variables such as the speed of the tool's release, the angle of the tool's release, and the targeting of physical variables like ideal height and weight, as well as the achievement in javelin throwing for talented individuals. It aimed to assist specialists in testing the ideal model of research variables in assessing the talents of javelin throwers. The study also addressed the problem of finding the relationship between the research variables and their correlation with the sample's performance. It explored the research objectives to understand the variables of the speed and angle of the tool's release, their relationship with the physical variables of ideal height and weight, and the achievement, as well as the relationship with the research hypotheses regarding speed, release, and angle of release.And its relationship with the variables of height and weight of the talented individuals and the achievement of the sample members, where it was found that the significant differences in the tests were in favor of the sample members in terms of the research variables. The researcher concluded the necessity of the optimal test and recommended conducting tests for talents according to the variables and achievement. Additionally, the testing of talents in other sports and samples should also be considered to play their role in reaching sports achievement to stardom and achieving the training goal.
