한국무용 팔 들어 감아올리기 동작 시 호흡이 부드러움에 미치는 영향

Abstract

The study of the five skilled (more than 10 years experience) and unskilled female korean traditional dancers participated in this study. Each participant performed the techique called "Pal duleo gamaoligy"(a technique where the participant raises their arm to the side above their head and move it in a circular motion and return to the starting position beside their hip) three times with abdominal respiration and with thoracic respiration. The kinematic data was recorded at 60 Hz with three digital cameras (Sony VX-2100). During this motion, the Jerk Cost (JC) factor was calculated for the shoulder, elbow and wrist to quantify the smoothness. Kwon 3D V.3.1 and MS Office Excel 2003 were used to calculate these variables. To investigate the relationship between the skill level and the breathing with the smoothness, two-way ANOVA for repeated measures was applied. There was no significant difference between the skill level and breathing for the wrist's and elbow's vertical and anterior posterior JC factor. There was a significant difference (JC was higher) recorded for the shoulder's JC factor while the subject participated in abdominal respiration. It was therefore concluded that there were not enough subjects used in this study so a significant difference could not be shown. To remedy this a future study must be carried out with more trials and subjects.
