Biomechanical parameters and its relationship with body rotation to the front tucked with ½ turn on parallel bars for youth Iraqi national team

Abstract

The rightful usage of modern technique takes an important part in achieve accomplishment, especially in gymnastics, one of the most important skill on parallel bars is the front tucked with ½ turn landing that must performed by gymnasts. That skill means landing on earth peacefully after completing ½ turn on parallel bars, velocity concerned one certain decisive factor to achieve the accuracy, aesthetic of performance, which determined through biomechanical motion analyses. And one of the important dimensions that have to do with the speed of rotation of the body for the skill front tucked with ½ turn on the parallel bars, as for the research problem. Through the researcher's observation of the performance of this skill among the young players during the tournaments, the researcher noticed that there is a discrepancy and difference between one player and another in the performance of the skill of rolling downward facing with half a turn on the parallel bars or the speed of performing this skill. The aim of the research is to find the relationship on the research sample consisting of (6 ) for two attempts on the youth team players and used special measurements, not extracting the results, and the researcher concluded that there is a relationship between the speed of body rotation for the skill of the revolving landing facing with half a turn on the parallel device with the angular velocity of the knee and hip joints and the height of the hip and the foot and recommended the development of the angular velocity of the knee joint and the angular velocity of the hip joint Young gymnasts have a parallelepiped in the implementation of the frontal bal
