The relationship of certain values of angular difference and angular velocity to rotational steps in triple jump with numerical implementation

Abstract

The kinematic analysis is used to accurately determine the performance level of the players’ movements and athletic abilities, which allows the values of the kinematic variables to be extracted and compared with the typical kinematic variables to know the strengths and weaknesses of the players’ performance and contribute to change the performance for the better, as our research aimed to investigate the relationship between the values of the time variable The angular velocity of the pivot phases in triple jump and the level of digital performance.
We used a descriptive research based on the method of motion analysis using kinematography, and the research sample consisted of Four (04) national champions in triple jump, who were deliberately selected. After analyzing and discussing the results, we came to the following conclusions, There is a significant correlation between the angle difference in hop push and performance (R=-0.982) . And a existence of significant correlation between angular velocity and performance only in step (R =0.979) and jump (R=0.981) because angular velocity is the result of angular difference divided by time, so the greater the angular difference with stability or lack of time, the greater the angular velocity.
