A Biomechanical Analysis of the CLOSED CHANGE STEP Motion in Waltz by Pre-Taping and Post-Taping

Purpose: The purpose of this study is to quantitatively identify the characteristics of lower extremity movements before and after taping during the closed change step motion in waltz for dance sports experts by using the functional taping, which is widely known for the prevention and treatment of the sports injuries, and also provide coaches and athletes with the appropriate posture and injury prevention by offering the basic data for the technical performance. Method: As for the subjects of this study, 8 female experts with 5 or more years of experience in dance sports in the metropolitan city of B were selected and experimented. Prior to entering the experiment, a consent was secured from each subject, and the method of the experiment was explained, while the kinematic data were collected by using 5 digital cameras. As for the statistical processing of this study, the joint angle data were calculated before and after taping during the closed change step motion by using the SPSS 24.0. First, the mean and standard deviation were obtained, and in order to analyze the difference before and after taping, and time and phase, a corresponding sample t-test was conducted. The level of significance was set to α=.05. Results: As a result of the experiment, it turned out that taping did stabilize the joint balance rather than causing problems for the mobility of the lower extremity joints via a biomechanical analysis of the lower extremities during the closed change step in motion waltz, and it is determined that it may have significance in that it provided the basic data required for the injury prevention as well as for the efficient performance of movements. Conclusion: Gathering the conclusions as such, it is determined that taping may have significance in that it stabilizes the joint balance during the closed change step motion in waltz and provides the basic data required for the efficient performance of movement and the injury prevention.
