PURPOSE: The aim of this study was to improve dancers’ performance in Sauté jump through “Thera-band ankle and foot exercises”. Our hypothesis was that with “Thera-band ankle and foot exercises”, dancers can enhance jumping performance and technique. METHODS: Twenty undergraduate dance major students (17 female and 3 male) were chosen to participate in this study, ten of them were in an experimental grope with training intervention, and the others were in a control group without training. Delsys Wireless EMG System to collect calf muscles activation, Motion Analysis System to collect kinematic data, and AMTI force plate to collect foot push impulse. The intervention of this “Thera-Band Ankle and Foot Exercises” used elastic exercise bands. Each practice was ninety minutes weekly for total of eight weeks. The data were entered in SPSS statistical software. Tests were performed before and after the training intervention. The significance level was set at α = .05. RESULTS: The results showed that eight weeks training with the “Thera-band ankle and foot exercises” for ballet Sauté jump significantly improved the performance. CONCLUSIONS: Through “Thera-band ankle and foot exercises”, the jump height of the ballet Sauté was significantly improved for the experimental group compared to the control group, and the push off impulse of the ballet Sauté jump was significantly improved for the experimental group compared to the control group, the muscle activation of the gastrocnemius during the ballet Sauté jump was significantly changed. The findings of this study provided information for educators and researchers as a reference.
