An Analytical Study of Some Biokinematic Variables and Their Relationship to the Long Jump Performance of Female University Students in Iraq

Abstract

This study aimed to determine the values of selected biokinematic variables in the performance of the long jump among female university students in Iraq, and to examine the relationship between these variables and performance level. The research sample consisted of five of the top female participants in the 2024 Iraqi Universities Championship (long jump), held at the University of Sulaymaniyah Stadium. Video recording and modern scientific techniques were employed to analyze performance and extract the required biokinematic variables, alongside the use of a graphic scale and the implementation of both pilot and main experiments. All attempts were conducted in accordance with the international rules of the long jump, and the best attempt was selected for analysis.

The collected data were statistically processed using the Statistical Package for the Social Sciences (SPSS), including the calculation of the mean, standard deviation, coefficient of variation, and simple correlation coefficient. The results indicated a statistically significant positive correlation between step length and step time and overall long jump performance. Additionally, variables associated with the collision and absorption phases showed significant relationships with performance level. Variables related to the propulsion and take-off phases also demonstrated statistically significant associations with performance, particularly regarding influential factors.
