| Abstract | ||
| The triple jump is consider one of the track and field competitions that is distinguished by difficult technique which include the approach run , hop, step, jump and the landing phases , and considering of what these phases need of high physical and skill training , and to recognize to the features of these phases and standing-up of the variables that should attention with to improving and developing these phases, the study problem was specified in study the bio-kinematical variables that effect in triple jump phases performance specially the last three steps variables that effect largely on the take-off and with relation to the approach run velocity and fulcrum angle (the frontal body fulcrum angle) and other body angles, also the take-off phase with it’s two parts (collision absorption- absorption push) in addition to fulcrum and take-off angles for the phase itself. The research aims to identify: 1 – Values of achievement of the research sample 2 – values of some bio-kinematical variables for the last three steps and take-off phases in the triple jump for a sample research. 3 - The relationship between some bio-kinematical variables for the last three steps and take-off phases in the triple jump and achievement. The researchers had hypothesized that there is a significant correlation between some bio-kinematical variables for the last three steps and take-off phases in the triple jump with achievement. The researchers used the descriptive method with the analysis and correlations style for its convenience to the research nature. The research sample consisted of (6) jumpers representing advanced players participating in the Iraqi tournament of triple jump . The researchers had used measurement, test and technical scientific observation as a tools for data collection, technical Scientific observation was carried out by using four video cameras , three of them were placed on left side of player to obtain the values of bio-kinematical variables of (hope , step, jump)phases and the fourth was placed in the face of the player to extract the deviations paths that player passes by side, A yard stick of one meter was used and filmed in both positions (horizontal and vertical) to calculate alteration coefficient from the image to reality in order to obtain bio-kinematical variables. each player has performed (6) attempts and the best attempt at achievement analyzed using computer softwares for kinetic analysis. Data were statistically handled treated through applying (spss) program to obtain (the arithmetic mean, standard deviation , the simple correlation)as well as equations correlated with biomechanics variables. | ||
