연풍대-한발 딛고 뛰며 앉았다가 발 바꿔 공중돌기 동작 시 점프구간의 운동역학적 분석

초록

This study suggests to provide basic data for drafting the learning plan for the non-expert through the kinematic analysis of Korean dance 'Yeonpungdae One step jump and Sit down and change feet jump. The results of this study were as follows. In the time variable, it was shown that the skilled person shortened the jump time for jumping and lengthened the running time. In the distance variable, there was no significant difference between the left and right position and the posterior position in the change of the center of mass position of the skilled and unskilled persons, but the change of the vertical position was slightly higher than that of the non-expert. The center of mass velocity of the jumping movement showed that there was no difference between the front and rear axes and the left and right axes of the skilled and unskilled persons, but the skilled person was the fastest at the vertical velocity. The ankle angle, knee angle, and hip angle were significantly higher in the junior than in the non-expert. Comparing the angle of the upper body when sitting for the jump, the expert showed that the upper body was kept straight and the posture was taken to improve the stability of the body center and the performance of the jump.
