Abstract

The aim of this study was to investigate the single leg sway characteristics of dancers whilst balancing on a rotating platform that was being used as part of a specific choreography they were training to perform. Seven professional dancers held a single leg standing posture on a rotating platform for as long as they could. The rotating platform was mounted on a force platform allowing the measurement of sway variability in the antero-posterior and medio-lateral directions. Participants’ sway was analysed over the initial and final 10 seconds of the trial. Medio-lateral sway was found to be similar to antero-posterior sway at the start (p = 0.766) and end (p = 0.938) of the trial. Six of the seven participants showed reductions in both AP and ML sway. Although no statistically significant changes in antero-posterior (p = 0.201) or medio-lateral (p = 0.064) sway were observed between the start and end of the trial with all seven participants included, reductions in sway were seen that showed large effects (AP = 0.94; ML = 1.55). With only the six participants included in the analysis that showed reductions in sway, ML sway was found to significantly reduce between the start and end of the trial (p
