용무도 앞굴러치기 동작의 운동역학적 분석

다국어 초록 (Multilingual Abstract)

The purpose of this study is to kinetic analysis of the apgulleochigi motion of Yongmoodo. And the kinematic variables such as the duration time, COM(center of mass) displacement and velocity, the maximum impact force at landing were analyzed. And the following conclusions were drawn. First, the duration time of the apgulleochigi motion of Yongmoodo was 0.42±0.06 s in P1, 0.48±0.06 s in P2, 0.24±0.10 s in P3, and the total time was 1.14±0.16 s. In addition, the time required for each section during apgulleochigi motion of Yongmoodo showed a long duration time in the order of P2, P1, and P3. Second, the left and right displacements of COM of apgulleochigi motion of Yongmoodo were 0.40±0.05 m for E1, 0.39±0.03 m for E2, 0.39±0.08 m for E3, and 0.37±0.07 m for E4. The displacement before and after COM was 0.52±0.28 m for E1, 0.86±0.22 m for E2, 1.44±0.12 m for E3, and 1.86±0.13 m for E4. COM vertical displacement was 0.99±0.03 m for E1, 0.68±0.04 m for E2, 0.55±0.12 m for E3, and 0.31±0.01 m for E4. Third, the COM left and right velocity of apgulleochigi motion of Yongmoodo are -0.03±0.07 m/s for E1, 0.00±0.07 m/s for E2, -0.02±0.18 m/s for E3, and -0.13±0.33 m/s for E4. The velocity before and after COM was 0.69±0.22 m/s for E1, 0.86±0.18 m/s for E2, 1.56±0.52 m/s for E3, and 2.03±0.15 m/s for E4. The COM vertical speed was -0.36±0.15 m/s for E1, -0.89±0.17 m/s for E2, -1.19±0.44 m/s for E3, and -0.03±0.34 m/s for E4. Fourth, in the apgulleochigi motion of Yongmoodo, the maximum impact force generated by the hand closing to the ground was 1.76±0.25 BW. In summary, in the apgulleochigi motion of Yongmoodo, it would be advantageous to increase the duration of P1 and increase the impact speed upon landing in order to minimize the impact. In addition, it is judged that the impact force is reduced as the right arm is closer to the ground before the upper body is lowered and the vertical velocity of the COM is slowed down during an impact.
