Analysis of Key Biomechanical Variables in Iraqi High Jump Champions

Abstract

The mechanical movement of the body during the study phase of the flight and upgrade over the crossbar of the importance of access to perform well in the effectiveness of the high jump to achieve the necessary amount of movement To overcome the gravitational pull on the one hand and to get the proper height to cross the bar on the other hand Houma called in the science  BioMechanical external forces, including the forces of friction football ground from the moment of the beginning of leaving the earth beginning to live up to the moment of the beginning of the upgrade  over the bar and to identify upgrade angle which found its impact is important and essential in the necessary strength valuesTo cross the bar properly access appropriate for landing, in the stages of upgrading the three high-jumping from the values ​​of the force equivalent to two to three times body weight for the amount of movement suitable for passing the bar and the investigation of aviation arc required in Technique well in line with the effort by the jumper.
