Exploring the Integration of Sports Biomechanics in Chinese National and Folk Dance Education: A Biotechnological Approach

Abstract

This study employs an 8-lens high-speed infrared motion capture system to analyze the motor biomechanical data involved in the string tumbling technique, a key element of Chinese folk dance. By comparing biomechanical parameters between elite classical dancers and trained students, we derive a nuanced understanding of motor efficiency, focusing on three key aspects: time characteristics, center of gravity shifts, and movement fluency. These parameters aid in developing a formal description language for folk dance movements, enhancing the pedagogical approaches in dance education. The analysis reveals significant differences in performance metrics; elite dancers complete each movement phase in an average of 0.59 seconds, while student dancers require between 0.73 and 0.85 seconds, indicating a 0.14-0.26 second delay. Additionally, the spatial precision of movement, as measured by the deviation of center of gravity along the X-axis, shows a narrower range of 354 mm for elite dancers compared to 587 mm for students. These findings not only highlight the potential of biomechanical analytics in refining dance training methodologies but also suggest their broader application in cultural preservation and enhancement of folk-dance education. The developed biomechanical analysis system provides a robust framework for the quantitative assessment of dance movements, offering a valuable tool for educators and researchers in the field of dance biomechanics. By integrating sports biomechanics into the teaching of traditional dance, this research contributes to the broader goals of cultural preservation and innovative educational practices, aligning with biotechnological advancements in sports and human performance studies.
