Abstract
국문요지 본 연구는 윤축원리의 타격 동작에 관한 과학적인 규명과 인체의 근 수축 기전에 대한 이론적 틀을 제공하기 위하여 원-투 스트레이트를 선정하였다. 이에 따른 대상자는 근 골격계와 관련된 병력이 없고, 그밖에 신체적 결합이 없는 경력 7년 이상의 우수선수 9명을 선정하여, 윤축과 3분절 회내 복합동작의 쓰임에 따른 회선 회전을 규명하기 위하여 세 가지 Type에 따른 운동역학적 분석과 지면반력, 8개 근육의 근전도, 충격력 측정을 통하여 정확성의 원리를 설명하고, 신체 각분절의 움직임에 대한 기초 자료를 제공하는데 목적이 있다. 1. 운동학적 분석 신체중심변위의 X축 type 1과 3에서 DM 0.05m로(p<.05), 손의 최대속도 phase 1에서 type 2와 3은 DM 0.75m/s로(p<.05), 왼쪽 어깨관절 Z축 event 3에서 type 2와 3은 DM 27.47°로(p<.05), 오른쪽 어깨관절 Y축 event 3에서 type 2와 3은 DM 14.43°로(p<.05), Z축 event 3에서 type 1과 2는 DM 17.37°, type 1과 3은 DM 22.54°로 유의수준에서 차이를 보였으며(p<.05), 팔꿈치관절 각속도 phase 1에서 type 1과 3은 DM 4.84°/s로(p<.05), phase 2에서도 type 1과 2는 DM 12.95°/s, type 1과 3은 11.72°/s로 유의수준에서 차이를 보였다(p<.001). 2. 운동역학적 분석 좌ㆍ우 지면반력의 왼쪽 Fz방향에서 type 1은 DM 1351.16Nm, type 2는 DM 1227.42Nm, type 3은 DM 1169.38Nm, 오른쪽 Fz방향에서 type 1은 DM 639.16Nm, type 2는 DM 652.86Nm, type 3은 547.43Nm로 나타났다. 적분근전도 phase 2에서 BR(전완근) type 2와 3은 DM 7.19%로(p<.05), UT(승모근) type 1과 3은 DM 4.81%, 2와 3은 1.00%로 유의수준에서 차이를 보였다(p<.05). 윤축과 3분절을 이용한 phase 2의 type에 따른 근 전위 활성화는 type 1에서 LE는 DM 14.22%, TB는 DM 13.07%, UT, DM 9.57%, type 2에서 LE는 DM 17.17%, LD는 DM 13.96%, UT는 DM 13.38%, type 3에서 RA는 DM 15.69%, UT는 DM 14.38%, BR은 DM 14.27%로 나타났다. 충격량에서는 시간, 속도, 각속도 순서와 유사한 결과로 전후방향 X축 type 2에서 DM 72.01Volt, type 3은 DM 70.93Volt, type 1은 DM 58.19Volt로 나타났다. 본 연구의 종합적인 결과를 토대로 윤축과 3분절의 세 가지 type 효과는 하지관절 각 변위와 지면반력의 차이는 없었지만, 팔꿈치 각속도에서 회내하는 동작이 회내하지 않는 동작에 비해 빠른 각속도가 나온 결과로 인해 윤축과 3분절 원리를 적용시킨 스크류 펀치에서 높은 위력이 나타났다. 그리고, 윤축과 3분절의 type 1은 LE(척추기립근), TB(상완삼두근), type 2는 LE(척추기립근)와 LD(광배근), type 3은 BR(전완근)과 UT(승모근), RA(복직근)의 근 전위 활성화의 결과를 확인할 수 있었다. 그러므로, 원-투 스트레이트는 윤축과 3분절 회내 복합동작의 하나로 정의할 수 있을 것이다.; ABSTRACT Biomechanical Analysis of the Pronation Complex Movement on Wheel Axle and 3-Segmentation Kim, Seong-Joo Dept. of Physical Education The Graduate School Hanyang University This research selected one-two straight to provide the theoretic frame on the scientific identification and muscular contraction base of physical body on the batting movement of wheel axle principle. For this research, 9 excellent players are selected by applying the following requirements; no previous disease in bone and sinew, no other physical disorder, career over 7 years. Then, kinetic analysis in 3 types to clarify the revolution per using wheel axle and complex pronation movement in 3 segmentation, reaction force of the ground, electromyogram of 8 muscles and impact were measured to explain the principle of exactitude and basic materials on the movement of each segmentation of physical body will be provided. 1. Kinematics analysis The difference in significant level was observed in type 1 &3 on X axis at DM 0.05m(p<.05) of physical center displacement, type 2 &3 at DM 0.75m/s (p<.05) in phase 1, maximum speed of hand, type 2 &3 at DM 27.47°(p<.05) in event 3 of Z axis left shoulder joint, type 2 &3 at DM 14.43°(p<.05) in event 3 of Y axis of right shoulder joint, type 1 &2 at DM 17.37° in event 3 of Z axis and type 1 &3 at DM 22.54°(p<.05). The difference in significant level was also observed in type 1 &3 at DM 4.84°/s(p<.05) in the phase 1 of angular velocity of elbow joint, type 1 &2 at DM 12.95°/s in the phase 2 and type 1 &3 at 11.72°/s(p<.001). 2. Exercise and kinetic analysis In the left Fz direction of left/right ground reaction force, type 1 showed DM 1351.16Nm, type 2, DM 1227.42Nm, type 3, DM 1169.38Nm and in the right Fz direction, type 1 showed DM 639.16Nm, type 2, DM 652.86Nm and type 3, 547.43Nm. In the phase 2 of integral electromyogram, difference of significant level was shown, namely, type 2 &3 of BR(forearm muscle) at DM7.19%(p<.05), type 1 &3 of UT(trapezius muscle) at DM 4.81% and 2 &3 at 1.00%(p<.05). In the muscular electric potential activation as per type at phase 2 using wheel axle and 3-segmentation, LE-DM 14.22%, TB-DM 13.07%, UT, DM 9.57% in type 1 and LE-DM 17.17%, LD-DM 13.96%, UT-DM 13.38% in type 2 and RA- DM 15.69%, UT- DM 14.38%, BR- DM 14.27% in type 3. In the impact, the result was similar in the order of time, velocity, angular velocity. The result was DM 72.01Volt in the type 2 of front and rear direction X axis, DM 70.93Volt in type 3 and DM 58.19Volt in type 1.Based on the general result of this research, there was no difference in each displacement and ground reaction force of lower limb with respect to the 3 type effects of wheel axle and 3-segmentations. However, the pronation movement showed higher angular velocity than the movement without pronation in the angular velocity of elbow. Thus, the power was high in the screw punch to which wheel axle and 3-segmentation principle was applied. Further, type 1 of wheel axle and 3-segmentation could check the result of LE (spinal erection muscle), TB(triceps of upper shoulder), type 2 could check LE (spinal erection muscle) and LD(Latissimus dorsi) and type 3 could check BR(forearm muscle), UT(trapezius muscle), RA(abdominal muscle). Thus, one-two straight can be defined as one complex pronation movement of wheel axle and 3 segmentations.
