태권도 주춤새 지르기 동작의 운동학적 분석

초록

This study was designed to compare Juchumseo Jireugi to new Juchumseo Jireugi that can be widely conducted in the athletics, and consequently, to represent new Juchumseo Jireugi in Taekwondo. Six healthy university students in the Department of Sport and Leisure Studies at ChoongNam province were screened, and individuals with a history of previous injury or surgery in their muscle, and skeletal systems. Subjects were performed in their Juchumseo Jireugi new Juchumseo Jireugi on the laboratory and take a rest during the performance. The motion analysis system named Kwon3d was used for measuring the body segment angle, change angle, angular accerlation, linear velocity and performance time. The results were as follows: 1. Time variable Total performance of Jireugi motion was more faster than Juchumseo Jireugi motion. but %Duration was more fast than Juchumseo Jireugi motion. 2. Angle variable In the angle variable(Two type of Jireugi motion), Each joint was represented in this paper. in the Event2, Angle of Elbow joint was more powerful than Juchumseo Jireugi. 3. Linear velocity & accerlation variable In the velocity & accerlation variable(Two type of Jireugi motion), Linear velocity & accerlation of Right hand was faster than Juchumseo Jireugi. 4. Angular accerlation variable The large change of angular accerlation was not existence. but right wrist angular accerlation represented that E3(two type of Jireugi) moton was 126.6±26.45deg/s² and 178.1±20.31deg/s².
