Abstract

The study aims to answer the following questions:What is the relationship between the biomechanical variables in the stage(approach, jump, flight)and the percentage of their contribution to achieve the effectiveness of long jump as well as the percentage of contribution of these biomechanical variables in the stage(approach, jump, flight) to achieve the effectiveness of jump The research community was selected from the students of the third phase of the Faculty of Physical Education and Sports Sciences at the University of Qadisiyah for the academic year(2018-2019)and the number(184)students, the sample of the research was chosen in a random manner and lottery, which represents two divisions are- and( number 48) Student was excluded Each of the repeaters and teachers,wherethe number became(33)students,and was conducted homogeneity and testing of the sample and then recorded in a special form where all the data of the players and analyzed by the program(Kenova)and then statistically processed by the program (spss), were presented,analyzed and discussed the results,Conclusions show that the most important variables that contributed to improving the achievement of the approach phase are(the distance of the last step, the angle of contact with the ground before the upgrading on the plate), while the upgrading stage was the most influential variables (knee joint extension time+speed of departure,angle of departure, maximum flexion For the knee joint on the floor) and stage Flight (maximum height reaches the body) and emphasize all technical stages (approach, upgrade, flight, landing) of the activity without exception and in particular approach approach,for the recommendations need to emphasize all technical stages (approach,upgrade,flight,landing)oftheactivitywithoutexceptionGetclose.
