The purpose of this study was to compare Biomechanical energy and muscle activation analysis of according to K-Pop dance level. Thirteen subjects(5 men, 8 women) who K-Pop dance professional choreographer were participated in this study. We divided 40 dance song 2 groups: level 1 (26.4±2.85kcal), level 2(49.65±5.53) based on of energy consumption. In order to measure muscle activity, the delsys (USA) was used. Seven muscles (biceps brachii, triceps brachii, rectus abdominis, rectus femoris, biceps femoris, tibialis anterior, gastrocnemius) activation were analyzed. As a result, Muscle Activity of all the segment does not affect the energy consumption. but, Depending on level, biceps femoris muscle activities were significantly different. Second, mechanical energy and energy consumption has an effect to each other. Third, Level 2 used more mechanical energy than the level 1. And according to level, potential energy, rotation energy and kinetic energy showed statistical different.
