The research aims to:
- Identify the missing distance between the player's foot and the jumping board in the first phase.
- Determine the contribution ratio of vertical and horizontal jumps to the body's center of gravity during the performance stages of the triple jump.
- Determine the contribution ratio of differences in stride length and fluidity for each stage of performance in completing the triple jump.
The researchers used the descriptive method with a correlational approach, which is the closest to the nature of the problem and suitable for the methodology followed to solve it.
The process of identifying and selecting the research community is one of the first and most important steps in scientific research. The researcher identified the research community and its participants, represented by effective triple jumpers participating in club and sports institution championships. They were selected deliberately to ensure conditions and circumstances compatible with the research procedures, with necessary approvals obtained for research procedures. The research community consisted of 12 jumpers representing 100%, while the research sample consisted of 10 jumpers representing 33.83% of the research community after excluding two jumpers due to injury and withdrawal from the championship.
