أثر تمارين خاصة في تحسين بعض المتغيرات البايوكينماتيكية وعلاقتها بأداء القفزة المتكورة على منصة القفز

Abstract

The effect of special exercises on improving some bio kinematic variables and their relationship the performance if the revolving jump on the jumping platform .The research included five chapters , in the first chapter included the definition of research to clarify the research idea in the introduction ,which summarized the importance of this problem , and the way to treat it is an application addition , and what the special exercises play in improving the kinetic pathways in the processor of kinetic transmission between parts of the body . The second chapter dealt with the most important topics related to the subject of the research. In the third chapter, the educational approach was determined, which is desirable to the nature of the problem and its solution, and confirming the validity of the hypotheses. the research sample was divided into two groups, one experimental group trained on the proposed special exercises, and the second group trained on its regular program. AS for the four-chapter subject to the results of the procedures and statistical treatments, and in the light of that, the validity of the hypotheses was verified or proven that the effect of the special exercises was positing the performance of the ball jumping skill.
