KINEMATIC ANALYSIS OF MUSIC’S INFLUENCE ON BODY EXPRESSION

ABSTRACT Introduction Dance is a combination of strength and beauty. Improving the expression of body movements in dance can improve the artistic quality of the performers and provide a greater visual experience to its spectators. Objective Explore the influence of music on dancers’ upper limb movement expression through kinematic analysis based on movement mechanics. Methods The factors influencing the expression of body movements and sports training in the dance process were investigated via a questionnaire. A group of 20 volunteers performed a movement performance only through a specific rhythm, while the experimental group combined the full music with the dance moves. After a set of four dance movements, the completion time, trajectory length, speed, and acceleration of the upper limbs were recorded and rated, analyzing the fluency of the two movement groups. Results Dance movement does not interfere as much with the rhythmic control of professional dancers; however, it impacts their fluency, range, and motion. Conclusion With the cooperation of music, the dancers’ movements were more harmonious and smoother, bringing a better expressive effect to the upper limbs. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
