Abstract
A lateral bias has been previously reported in dance training. The aim of this study was to investigate whether there are any bilateral differences in peak forces, power, and maximum knee flexion during a sequence of three grand jetés and how they relate to leg dominance. A randomised observational design was selected for the study. Volunteers consisted of 20 female dancers in the last year of pre-professional training. All volunteers completed three different tests to determine leg dominance prior to completing a three grande jeté sequence. The lead leg for the jump sequence was randomised. Peak take-off power, relative landing force (BW), and maximum knee flexion angles were measured using a Myotest accelerometer and integrated goniometer. Results indicated that 90% of dancers reported right leg dominance. A significant difference was noted in peak take-off power among the jumps (p<0.01); post hoc test indicated jump 3 was significantly greater than jump 1. Mean maximum take-off knee angles increased over the three-jump sequence with the left leg having a significantly deeper plié than the right (p<0.01). Landing data showed an increase in peak force and a decrease in maximum knee angles across the jump sequence. The present data indicate different bilateral strategies during take-off and landing during grand jetés in female dancers resulting in increased forces during the jumps on the non-dominant side. These differences need to be addressed by incorporating appropriate modifications in training methodology that eliminates the observed bilateral differences.
