A WORLD BIO-KINEMATIC MODEL TO EVALUATE ACHIEVEMENTS OF TRIPLE JUMP PLAYERS FOR THE ADVANCED IRAQI

The triple jump is one of the vital and important games in the program of track-and-field games. In addition, it is considered one of the technical games as, in performance; it depends on a lot of kinematic variables. Generally, it includes many consecutive technical phases which require research for the purpose of raising the level of technical performance and achieving new Iraqi records. The study aims to determine the values of kinematic values for the world champions and Iraq advanced category champions and put a model for each phase of triple jump performance phases (hop, stride and jump) with the significance of the kinematic variables proposed by the staff which consists of 18 researchers supported by the World Federation of Athletics in Berlin, 2009 and Daegu 2011 for track-and-field games. Population of the study was represented in jumpers and participants in Iraq’s clubs and institutions championship held in the capital, Baghdad, on 22/10/2014. The sample of the study was chosen from the top eight. 26 attempts were analyzed of the total of six legal attempts for each jumper and comparing them with 16 attempts of world champions. 4 video cameras with frequency speed of 300 P/s were used and put on the left side of the approaching road on a distance of 7 m. the following variables: (speed and its decrease, touch and take-off angles, angles of knee and trunk, distance of each phase, touch times, etc) were used. The study reached three different models for each phase separately. Among the most important conclusions, there are: the variable of support duration came at first place of importance in all extracted models and all technical phases, the Iraqi model for the advanced gives importance for not losing horizontal speed at the hopping phase. As for the world model, it does not give great importance for this variable as it does not tend to decrease horizontal speed, but keeping it, the model of Iraqi jumpers is more stable than the world model at both phases of hopping and stride and the reverse in jumping phase. There is an inverse relation in some variables between the world and Iraqi models which means that there is a difference in performance method.
