Dance Sports Medicine Health Sciences dance fatigue electromyography drop landing Background: Reports suggest that as many as 97% of dancers experience injury. Dance is very physically demanding and requires a great number of jumps with single leg landings. Dancers generally have poor fitness which can lead to fatigue. Fatigue alters movement and landing patterns and may contribute to dancers’ injuries Purpose: The purpose of this study was to determine the effect of fatigue on lower extremity muscle activation in dancers using a dance-specific fatiguing protocol and a functional dance landing test. Methods: A total of 18 healthy Ohio University Dancers were recruited to perform a drop landing task in coupe. This task was performed prior to and after fatigue. Surface electromyography was used to evaluate muscle contraction amplitude bilaterally and peroneus longus muscles at time of peak vertical ground reaction force. Main outcome measures: Pre- and post-fatigue muscle contraction amplitudes. Results: No statistical significance was found between pre- and post-fatigue conditions. Conclusion: Muscle contraction activity in the ankle and hip may not be affected by fatigue, suggesting that jump training in dance is sufficient to reduce the negative effects of fatigue. However, dancers may not accurately judge their fatigue levels and should be monitored for fatigue. 2018-06-11 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1523461882235808 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1523461882235808 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
