Abstract

The current study aims to analyze the performance of long jump contestants (under 16, under18, under 20 years and the high level) during national championships, The study attempted to determine the values of some kinematic variables of the final approaching phase (last twosteps) and takeoff for long jump contestants (under16, under18,under20 and high level) and comparing kinematic variables for different age groups to determine the dynamics of enhancement for some variables affecting performance in the long jump. The sample consisted of twenty three contestants from the national champions, Data was collected by means of measurement, video recording and movement analysis. As a results,1- Rate of horizontal acceleration and resultant velocity directly before takeoff, increase as the age group gets higher but there is no significant difference between ages 18 and 20 years, 2- Rate of horizontal and vertical velocity at the moment of takeoff increases as age group gets higher for the sample individuals but there is no significant difference between ages 18 and 20 years and high levelin vertical velocity but it is present between 16 years old group and others, 3- A great rate of loss inhorizontal and vertical velocity for all contestants at  takeoff more that at the last step before takeoff ranging between 0.40 m/s- 0.67 m/s.
