RESUMEN
BACKGROUND: Augmented feedback strategies have been demonstrated to enhance jump-related biomechanics. Nevertheless, its effect on classical ballet is still unknown. The purpose of this study was to investigate whether a multimodal augmented feedback session is effective for improving lower limb and trunk kinematics during a classical ballet single-leg jump. METHODS: In a single-blind randomized controlled trial, 36 amateur classical ballet dancers were randomly assigned to either a control group (n = 18) to receive a brief warm-up session, or an augmented feedback group (n = 18) to receive, in addition to a brief warm-up session, a combined visual feedback session associated with verbal instruction. Hip kinematics in the frontal and transversal planes and knee and trunk kinematics in the frontal plane were analysed at baseline, immediate post-intervention, and one-week post-intervention. Intervention effects were analysed using a two-way, mixed model, repeated-measures analysis of variance. RESULTS: No interaction effects were observed, indicating that a single session of multimodal augmented feedback was insufficient to improve lower limb and trunk kinematics during a classical ballet single-leg jump in amateur classical ballet dancers. CONCLUSION: A single session of multimodal augmented feedback should not be used as the sole component in prevention programs intended to improve jump-related kinematics in amateur classical ballet dancers.
