The purpose of this study was to investigate the biomechanical of K-Pop dance movement. The study was conducted on 15 male and 15 female subjects in 20-30 age groups. And they choose 150 K-Pop dance choreographies in the top 10 ranking of the main charts. We analyzed the RoM, joint moment and impulse force of the highlight movements. First, During the K-Pop dance motion, the usage of knee joints are more than the hip joints and the ankle joints, and female dancers has a larger range of motion than the male dancers. Second, male dancer uses more than female dancers when they compared the load of male dancers and female dancers. In particular, flexion and extension of the hip joints are mostly used in this study. Third, the impulse force of male dancers was greater than of female dancers, but it was statistically insignificant, this is equal to the impulse on walking. In conclusion, Female dancers use more range of motion than male dancers, but male dancer choreography requires greater torque, which can strain joints. Most choreographic exercises involve movements such as hip joint, knee joint, flexion of ankle joint, extension, rotation, and jumping.
