Exploring the Effects of Kinesiological Awareness and Mental Imagery on Movement Intention in the Performance of Demi-Plié

Abstract : This study was designed to assess the ability of a practitioner intervention using kinesiological explanations and mental imagery techniques to optimize the performance of demi-plié in dancers. Seven professional female ballet dancers were involved in the study. Biomechanical and electromyographical parameters (maximum knee flexion, jump height, maximal vertical acceleration and its duration, ratio of sagittal acceleration variation, and ratio of muscle activity in four muscles of the lower limb) were analyzed before and after the practitioner intervention. Results demonstrated no significant difference in the depth of the demi-plié, nor in the height of the jump that followed, nor in the maximal vertical acceleration and its duration, leading to the suggestion that the technical potential of the dancers was preserved. Significant differences were found in the SEMG of the hamstrings during the demi-plié and the jump, implying that an improvement in the dynamic alignment of the dancers was present. A correlation was also found between the ratio of sagittal acceleration variation and the hamstring activity, suggesting that increased hamstring engagement produces decreased disruption of dynamic alignment. However, the intervention was not assimilated equally by all of the dancers.
