Fifteen professional dancers par-ticipated in this study, exceeding a weekly 15 hours of classes. The participants performed three trials of each jump in a randomized order on a force platform. The Sauté jump produced the greatest peak knee moment in both propulsion and landing phases, but the lowest rate of force development in propulsion phase. These results indicate that Sauté is performed with a deeper plié in both propulsion and landing phases, with small-er ground reaction force peak and knee peak force. This pat-tern of jumping may be less harmful and should be adopted in the other jumps by classical dancers who perform such exercises daily several times. Keyphrases: Jumps, demand, knee
