In classical ballet, jumping should stand more on technique and elegance rather than maximal height. This study aimed to investigate dancers’ ability to perform stable jumps with classical ballet technique. Twenty-two female dancers [divided in two groups: Expert: n=12; Novice, n=10] were recruited to perform three vertical jump protocols: 1) Changement de Pied (CHA), composed by 5 consecutive jumps; 2) Echappé (ECH), composed by two consecutive ‘Echappé’ jumps; and 3) Sissonne Fermé (SF) jumps. Through an Optojump Next system were measured: a) Height (H) of jumps; b) Jumping Point Gap (JPG) and c) Used Area (UA). The CHA analysis showed differences between consecutive jumps for JPG (p=0.003). An approach to significance (p=0.52) and a difference (p=0.42) between groups were found for H and JPG respectively, while no differences were found for UA. The ECH analysis revealed main differences between jumps for H (p<0.001), JPG (p=0.003) and UA (p<0.001), post-hoc analysis showed differences (p<0.05) between each jump from the fifth position to the second one and vice versa for H and UA whilst differences between groups emerged only for UA (p=0.001). The SF analysis showed no differences for all parameters. The results showed as in CHA dancers carried out a control on the jump height to maintain their “aplomb” and limit the medio- lateral displacement, which was also influenced by the dancers’ experience (NOV group showed higher H and JPG values). The dancers’ skill was also demonstrated by their ability to perform similar jumps in each of the two echappé cycles.
