This study was to investigate and compare the change of EMG amplitude and frequency order of muscular contraction by rhythm process in three, basic movements of Korean dance between the skilled and the unskilled. The muscles measured in this study were four of the right leg:Gluteus Maximus, Adductor Longus, Rectus Femoris and Gastrocnemius. The subjects were: females of S. high school of art in seoul: skilled 4, unskilled 4. The experimental appartus of EMG was a High speed Recorder located in the oral physiology labaratory of the College of Dentistry, Seoul National University The findings were as follow: 1. In all the three movements of Korean dance, the skilled showed markedly the use of muscles pear the Center of gravity(C.O.G) of the body-Gluteus Maximus and Adductor Longus - in controling the leg movement. 2. In all the three movement of Korean Dance, the unskilled showed markedly the use of muscles for the C.O.G of the body-Rectus Femoris and Gastrocnemius- in controling-the leg movement. 3. Frequency of EMG of the un skilled muscles was larger than that of the skilled muscles.;韓國舞踊 動作時 안정을 취한다 함은 부상을 방지하고 表現을 아름답게 하며 疲勞를 덜하게 한다는데서 중요하며, 이 안정은 下肢의 안정이 크게 左右한다. 따라서 本硏究는 熟練者 4名과 非熟練者 4名을 對象으로 韓國舞踊 基本動作時 下肢筋의 主動筋을 筋電圖로 分析키 위하여 서울大學校 齒科大學 口腔 生理學室에서 大臀筋, 長內轉筋, 大腿直筋, 비복근을 測定 分析한 結果 다음과 같은 결과를 얻었다. 1. 熟練者는 大腿에 있는 筋肉을 먼저, 下腿筋을 나중에 사용하였다. 2. 非熟練者는 下腿筋을 먼저, 大腿筋을 나중에 사용하였다. 3. 非熟練者의 放電 頻度는 熟練者의 그것보다 모든 動作, 筋肉에서 컸다. 4. 放電의 振幅은 熟練者와 非熟練者에서 차이가 없었다.
