유선식(Sun-Sik Yoo),유실(Sil Yoo),이재훈(Jae-Hoon Yi) 한국엔터테인먼트산업학회 2015 한국엔터테인먼트산업학회논문지 Vol.9 No.3
This study is to reveal the body alignment effects of yoga exercise focusing on the pelvis and spine which is the major joints of human body in the alignment. The 14 twenty-year-old women without any experience of yoga were participated in a training yoga session composed of 50 minute duration, 3 times a week for 24 weeks. 3D motion analysis was performed on the five selected yoga motions in order to verify the body alignment effects on the test subjects. The analysis of the results has been done with the average values taken from the two times selective motions. For the statistic validation, the paired sample t-test was utilized. After the training, the subjects first aligned their pelvis through the change in pelvic limb and then extend the spines and finally completing the posture by throwing their shoulders back. On the basis of biomechanical point of view, the consequence showed that the 24 weeks of yoga training has a positive effect in the pelvis and spine alignment. The yoga motions utilized in this study has proven to be effective in enhancing cognitive ability of the pelvis and spine.

The purpose of this study is to understand the pelvic movement centered on the 3 (X, Y, Z) axes, which are the basis of movement to improve pelvic posture recognition, and to provide a basic exercise that can be repeatedly trained with the rhythm. Therefore it can be easily utilized in the daily sports field to provide the program. Focusing on improving the ability of the exerciser to recognize his/her own posture, it was constructed around the rotational axis of the pelvis (X-left and right axis, Y-anteroposterior axis, Z-vertical axis), which can be the basis of movement. It consists of 9 movements: pelvic tilt exercise, pelvic rotation exercise, and pelvic hike & drop exercise , and the characteristics are as follows. First, the pelvic tilt (forward/backward) exercise is an exercise that adjusts the inclination in the anterior/posterior inclination direction by rotating around the left and right axes of the exerciser’s pelvis in an anatomical posture. Second, the pelvic rotation exercise is a movement in which the pelvis rotates about the vertical axis of the exerciser’s pelvis in an anatomical posture, and the pelvis rotates right front/left and right back/left forward. Third, the pelvic hike & drop exercise is a movement that rotates around the anteroposterior axis of the exerciser’s pelvis in an anatomical position. In addition, motions that can be performed in the lying position, the prone position, and the standing position are presented, so that the pelvis can be controlled in various positions in the three-dimensional space. Therefore, it is thought that the pelvic 3-axis exercise program to improve the ability of the exerciser to recognize his/her own posture can be utilized as the main exercise program for exercise beginners or rehabilitation exercisers as well as the warm-up and cool-down exercises of various life sports programs.
