Some Biokinetic Variables of the Approach and Take-Off Phases and Their Relationship with Long Jump Performance among Iraqi National Team Juniors

Abstract

Study Objectives: To identify the values of biokinetic variables during the approach and takeoff phases and their relationship with the long jump performance of the junior Iraqi national team, To investigate the correlation between the biokinetic variables of the approach and takeoff phases and the long jump performance of the junior Iraqi national team.

Methodology: The researcher employed a descriptive correlational design suitable for achieving the study’s objectives. The research sample consisted of six athletes, representing 100% of the original population.

Findings: A significant positive correlation was found between work (mechanical work) and performance during the approach phase, indicating that athletes who generate greater work are able to transfer energy more effectively, A correlation was observed between power output and performance in the approach phase, emphasizing the importance of producing energy at high rates over time.

Recommendations: Emphasizing the development of strength and speed due to their critical role in achieving successful long jump performance, Stressing the integration and coordination between horizontal and vertical kinetic energy through the enhancement of both horizontal and vertical velocity, aiming to achieve a balanced and comprehensive technical performance that leads to optimal results.
