Ballet is an athletic activity that combines aesthetics and artistry with power and skill. One of the most athletic aspects of dance is observed during jumps. Many jumps in ballet involve takeoff from a single leg, but differ in propulsion direction. To assess differences in mechanical demand, two single leg jumps commonly trained in ballet were compared; a saut de chat (SDC) and a temp levé from a step (SLSJ). Fifteen female classically trained dancers with similar number of years of training (13.9 ± 5.0 years) were instrumented with lower body reflective markers and performed each jump three times on a force plate. The marker position data and ground reaction forces (GRF) were captured synchronously at 250 hz and 100 hz, respectively, using a Vicon motion capture system. Peak vertical GRF, average rate of force development (RFD), peak ankle moment and peak ankle power were measured and averaged across trials. Paired t-tests were used to determine differences between the SDC and the SLSJ. When compared to the SLSJ, the SDC displayed significantly higher peak vertical GRF (p = .003), RFD (p = .002), and peak ankle moment and power (p < .001). Analysis of effect size for these differences revealed a large effect size for all variables (Cohen’s d > .80). In conclusion, results of this study indicate the mechanical demand of different dance jumps is diverse, which has implications for performance enhancement, injury prevention, and rehabilitation.
