BIOMECHANICAL APPROACH TO BALLET MOVEMENTS: A STUDY OF THE EFFECTS OF BALLET SHOE AND MUSICAL BEAT ON THE VERTICAL REACTION FORCES
Keywords: ground reaction forces, classical dance, ballet jump.
AbstractBallet movements can be the focus of biomechanical studies in order to better understand the characteristic mechanical loads of the locomotor apparatus related to classic dance. "Pointe shoes" have been associated to high incidence of morphological and physiological alterations of ballet dancer's feet, however its contribution to injury mechanisms must still be precisely known. On the other hand, movements like jumps and leaps are frequently repeated in a standard ballet training, where the musical beat also plays a role on the motor behavior and its mechanical aspects. Therefore the purpose of the present study was to describe ground reaction forces during the "saute -1st position" under the influence of footwear (slippers and pointe shoes) and musical beat in order to identify the relative contribution of these factors on the external loads measured. It was observed that the musical beat played a greater role on the ground reaction force magnitudes than the footwear.
