THE EFFECT OF USING A PROPOSED TOOL IN ENHANCING PERFORMANCE & ACHIEVEMENT LEVELS DUE TO SOME BIO-KINEMATIC VARIABLES OF THE JAVELIN THROW

The current study aims to identify the effect of the proposed tool in enhancing performance and achievement levels due to some bio-kinematic variables of javelin throw. Both researchers suggested that there is a positive effect of using the proposed tool on performance and achievement levels in javelin throw for the sake of the empirical group as they used the empirical method because it fits the nature of the study. The sample of the study was chosen from the first year students in the academic year 2012 ? 2013. They were 24 students divided into two equal groups (12 students each). The researchers designed a proposed tool to learn and train javelin throw on 15 educational units starting from the first introductory unit till the last unit in two units per week. Data were statistically processed using arithmetic means, standard deviations and the Ttests for related and equal samples. As for conclusions, the study showed a clear positive effect in enhancing and developing some angles of the body especially body inclination angle and launcher angle. This was shown from results of mechanical analysis of javelin throw skill which, in turn, was reflected in developing achievement
