Analysis of the relationship between some biomechanical variables and the level of technical performance of the front hands jump skill on the jumping table device

Abstract

The importance of the research came through the biomechanical analysis of the stages of this movement, as understanding the stages of performance on the jumping platform is of great importance because these stages affect one on the other and interrelate with each other to determine the achievement of the level of difficulty, and knowing the biomechanical variables will contribute to organizing and directing training operations from During the detection of weaknesses and strengths and give the necessary treatment.identify the relationship between some biomechanical variables with each other and the level of technical performance of the front hand jump skill on the jump platform device1-The research sample showed a great variation in the values of speed and angles in different stages of performance and according to what was stated by the mechanics of a body, whether it was of a horizontal linear direction or a vertical direction or with rotational or angular paths.2-It turns out that the research sample recorded a gradual increase in the values of the leaning angle, the landing angle, the knee angle, the hip angle, and the highest height of the hip joint point during the performance stages, and this is in line with the mechanical requirements for performance
