Finding the relationship between a number of biomechanical variables for the body and arms at the end of the push and the highest height of the body in flight at (hopscotch, step, and leap) in the triple jump of the sample .      The research sample included four jumpers in the triple jump event who represented the elite Nineveh Governorate team, participants in the Iraqi club championships in track and field games, and those who obtained advanced positions for the 2021/2022 sports seasons. The category of applicants was chosen intentionally,. (3) Canon type photographic machines with a speed of (120) images per second were used, as they were perpendicular to the field of movement and from the jumper’s right side when he performed (the hopscotch, the step, and the jump) to study the biomechanical variables of the movement of the arms and the body under study. After giving the jumpers three attempts, the best of which was analyzed according to performance and achievement. The researchers used the statistical package (spss) to extract the arithmetic means, standard deviations, coefficient of variation %, and simple correlation coefficient (Pearson) and Probability and error rate (sig) to find the relationship between the biomechanical variables under study with achievement the analyzes done with kinovea programmer .
