Abstract
Ballet dancers are exposed to the high likelihood of lower extremity injury due to repeated high impact jumps under stringent ballet rules. According to the claims of current literature, excessive vertical ground reaction force (VGRF) and the rate of force development (RFD) during the landing phase of a jump are highly associated with the incidence of injury. The aim of this study was to quantify the difference of the VGRF and RFD between novice and experienced ballet dancers during a ballet second position jump landing task. Twelve experienced ballet dancers and 12 novice dancers performed second position jumps on a force platform that was set flush to the floor. The peak VGRF (N) during the landing phase of the second position jump in the novice group (m = 369.3, sd = 96.8) was 58% greater (p < 0.001) than the experienced group (m = 154.0, sd = 59.6). Additionally, the RFD (N/s) during the landing phase of the second position jump in the novice group (m = 4412.6, sd = 1.3) was 67% greater (p < 0.001) than the experienced group (m = 1456.5, sd = 679.5). However, there were no significant differences in peak take off force, flight time, and jump height between two groups. This suggested that more precise and specific instruction for novice dancers is required to minimize impact force followed by preventing potential injury.
