Abstract
The skill of Pike sole circle backward to handstand on uneven bars is considered as skill of difficulty (C), which can be developed into even higher difficulty ((F (1) and that happened by entering the flight on the same bar or moving between the two bars or through changing fists by entering windings or also it can be developed by not putting the foot on the bars. The research aim: putting special exercises for The skill of Pike sole circle backward to handstand on uneven bars in the light of the most important biomechanical factors that effect on performance of this skill. Tools of data collection:
two-dimensional television, using a speed of 100 cadre / s . Analysis Program biomechanical with two-dimensional 2D to extract biomechanical variables Video Point V.2.5.
The results have shown the following: Keeping the center of gravity away from the axis of rotation in the preliminary stage has a positive role in increasing speeds of joints, shoulders, thighs, before installing feet on the bar. Bringing the center of gravity of the body from the axis of rotation by discouraging articular thighs by putting feet on the bar led to increase torque moment, inertia momentum, energy to spin for the body’s center of gravity at the end and the beginning of rising swinging. When you touch the feet of the bar, it must be with fingertip even reducing the friction force between the feet and the bar. What the player acquired in the previous stages had a positive impact to reduce gravity in the process of lifting.
