Biomechanical variables of the feet areas, using the technique of Dynafoot3, and their relationship to the skillful performance of defending the stadium with the two arms from the bottom facing the volleyball for the applicants

Abstract

The research problem is summarized is that the biomechanical variables of the feet areas with Dynafoot3 technology have a relationship with the skillful performance of defending the stadium with the arms from the bottom facing the volleyball for the applicants so that it gives us accurate results so the researcher considered going into this study by taking advantage of the technology as new and used in the field of volleyball to develop the game And to know the strengths and weaknesses of the players accurately, the study aims at the relationship between the biomechanical variables of the foot regions with Dynafoot3 technology and the skillful performance of defending the stadium with the arms from the bottom facing the volleyball for the advanced The researcher has identified a research community who are the advanced players for the Middle Euphrates clubs in volleyball for the 2019-2020 season of (53) players distributed over (5) clubs, and then the research sample was chosen and by (18) players representing the clubs (Al-Qasim, Kufa, Daghara) They make up 33.96% of the research community, homogenization of the studied sample was performed, then the test was done in the main experiment and dictated in a form prepared for that. All the players ’data is present in it. The system was used to obtain data for the players and was statistically treated by the spss program to identify the results on the desired results From the system, the results showed a relationship It is linked through the values ​​achieved from studying some biomechanical variables according to the Dynafoot 3 system with the skill of defending the stadium from the bottom with the two volleyball arms.
