الطاقة الميكانيكية خلال الدائرة الخلفية الكبرى كينموتسو (kenmotsu)‎ على جهاز المتوازي في الجمباز

Abstract EN

The purpose of this study is to demonstrate the mechanical energy changes in the whole body, and to determine the muscular work performed by the gymnastic during the back giant swing on parallel bars.

The subjects of the study consisted of three players who participated in the 2019 gymnastics World Cup tow Ara done turkey.

The videos were from the International Gymnastics Federation's website and the camera's frequency was 25 frames per second and vertical at the spatial level.

The analysis was two-dimensional by the biomechanical program (Skill Spector).

The results indicated that the low mechanical energy of the whole body is due to the friction between the hands of the gymnast and the two parallel bars, and air resistance.

To complete the spin, the player must do a muscle work to compensate for these energy losses.

So total mechanical energy changes with the relationship between energy loss and muscular work.
