룸바의 워킹스텝 시 하지관절각의 변화에 관한 동작분석

Abstract

The purpose of this study was to analyze the motions on the change of joint angles of the lower extremities in walking steps of rumba. For accomplishing the purpose of this study, the 10 women dance sport majors(high group: 5, low group: 5) were collected for the experiment. Variables of analyze were rotation of hip joint, angle of knee joint, angle of ankle joint and step width. In order to analyze the movement, this study was used DLT method adn Kwon 3D 2.1 program. The results of this study are as follows, First, in the preliminary movement of the right, rotation of hip joint were higher in the high group than the low group and step width was longer than low group showed differences between groups. Second, in the walking movement of the right, rotation of hip joint were high differences, angle of ankle joint diifferences between groups. Third, in the preliminary movement of the left, rotation of hip joint and step width were higher in the high group than low group. Fourth, in the walking movement of the left, rotation of hip joint showed high differences, step width showed diifferences.
