CORRELATIONS BETWEEN EXPERTS’ SCORING AND BIOMECHANICAL ASSESSMENT IN BALLET MOVEMENT

The purpose of this study was to investigate the relationship between assessment of ballet movement by experts and biomechanical variables. Releve point movement was recorded by a video camcorder (Sony, Japan) for the expert assessment. Eight infrared cameras (Qualisys, Sweden) and two force plates (Kistler, Switzerland) were used for biomechanical analysis. A High reliability in score for flexibility and assistance among three judges was found. Based on the analysis of correlations, flexibility and ROM were positively correlated as the subject who performed wider motion at the ankle achieved higher sores in flexibility from the judges. Negative correlations were found between the judges’ scores in assistance and ankle joint power as well as their scores in balance and COP on the left side. Development of objective and reliable scoring standards in ballet based on the understanding of body movements supported by the verification of scientific method is needed
