태권도 품새 중 두발 서기자세 옆차기와 학다리 서기자세 옆차기 동작의 운동학적 비교분석

Abstract

The purposes of this research are to analyze image and muscle activity between Yeopchagi of two-feet stance posture and Yeopchagi movement of Hakdari seogi posture among the Taekwondo Poomsae, obtain kinematic of two Yeopchagi, provide scientific basic data by finding movement organization factors, characteristics and similarities and differences of each seogi posture Yeopchagi, suggest effective direction of performance for guide’s correct guidance and Poomsae player’s Yeopchagi technological movement and contribute to the improvement of Poomsae player’s athletic performance. Research subjects were 6 male Poomsae players who were registered in Korea Taekwondo Association as Poomase players with career of get a prize and the experiment was conducted by 6 cameras. As a result, following conclusions could be obtained. BR First, for the total time required, Yeopchagi of Hakdari seogi posture was more rapid than Yeopchagi of two-feet stance posture. In the time required by condition, Yeopchagi of Hakdari seogi posture showed both increase and decrease in performance time, but Yeopchagi of two feet stance posture showed continuously decreased performance time by condition.BR Second, for changes of hip joint angle, angular speed and each acceleration, there were significantly statistical differences for the right angel of hip joint in EVENT1 and EVENT 2. And, angular speed [Right/E1,E2(p.001)] and each acceleration didn’t show significantly statistical differences.BRThird, for changes of knee joint angle, angular speed and each acceleration, knee joint changes of Yeopchagi of two stance postures show same similarities in EVENT 3 and EVENT 4 without significantly statistical difference. Knee joint changes show significantly statistical differences in EVENT 1 and EVENT 2. For changes of knee joint angle [Right: E1,E2(p.001)/Left: E1,E2(p.001)] and each speed change of knee joint, angular speed of right knee joint showed significantly statistical differences in EVENT 2 [Right: E2(p.05)]. And, in each acceleration, there was not significantly statistical difference in EVENT 1~EVENT 4. BRFourth, for changes of ankle joint angle, angular speed and each acceleration, ankle joint of kicking foot didn’t show dorsiflexion at the time of impact striking the target during both Yeopchagi of two-feet stance posture and Yeopchagi of Hakdari seogi posture. And, there were significantly statistical differences in EVENT1 and EVENT 2.
