도움닫기 거리에 따른 수직도 발구름시의 신체 각 관절의 공헌도
배정행(Bae Jeong-Haeng),배영상(Bae Yeoung-Sang),서창익(Suh Chang-ik) 한국체육과학회 2003 한국체육과학회지 Vol.12 No.1
The purpose of this study was to quantify the contribution of body joints for take off of two-foot vertical jump performances with the increase of approach distance. Eight male taekwondo players volunteered to participate as subjects in two-foot vertical jump experiment with one-step, three-steps and five-steps approach distance. The take off phase of vertical jumps were filmed by using 16㎜ high speed camera and measured the ground reaction force by using the force platform simultaneously. At take off, a elapsed time of downward phase was shorter than that of push off, and also decreased the elapsed time of take off with the increase of approach distance. For the downward and push off phase at take off, the contribution of knee joint muscle group was increased significantly with the increase of the approach distance. However, the contribution of hip joint muscle group was decreased significantly with the increase of the approach distance relatively. The legs were the greatest contributors for two-foot vertical jump of each approach distance. The summation of the contributions derived from legs were about 90% for downward and push off phase, respectively. And the contribution of the hip joint was about 50%. The results of this study indicate that while the legs contribution with the increase of approach distance were similar among one-step, three-steps and five-steps, the contributions of each joints of the legs employed to achieve these results were notably different.

제2형 당뇨병 여성환자들에게 있어서 운동이 혈당에 미치는 영향
배정행,이달원,김갑구 啓明專門大學 産業開發硏究所 2000 啓明硏究論叢 Vol.18 No.2
본 연구는 제 2형 당뇨병 환자를 대상으로 Walking, Jogging, Walking +Jogging 운동을 실시했을 때의 혈당농도의 변화에 대하여 실험하였다. 이 실험에서 W군, J군, W+J군은 운동 10분 및 30분에서 안정시 보다 증가하였으나, 회복 10분 및 30분에서 W군과 J군은 감소한 반면, W+J군은 회복 10분과 30분에서 별 차이가 나타나지 않았으며, 측정시기에서 유의한 차이(p<.05)가 나타났으나, 운동유형과 측정시기에서는 상호작용효과가 나타나지 않았다. 이상의 연구결과를 종합해본 결과 당뇨병 환자를 대상으로 한 더 많은 운동유형을 대상으로 실시하여 폭넓은 연구가 이루어져야 할 것으로 사료된다. Experiment - Walking, Jogging, Walking + Jogging- to TypeⅡ Diabetic patient shows change of Blood Glucose. Based on the experiment, change of blood glucose of Ws, Js, W+J, exercise 10min, and exercise 30min shows increase tendency. However, blood glucose of Ws and Js of recovery 10min and recovery 30min shows decrease tendency. Blood glucose of recovery 10min and 30min shows no difference Even though, measurement point shows difference (P<.05), there is no relation between exercise type and measurement point. Considering analysis results, studies of various exercise type for the typeⅡ diabetic patients will be required for exercise therapy improvement.

The purpose of this study was to investigate jumping ability in order to establish proper methods of strength and power training for jumping as pertains to sports. Jumping in sports requires higher jumping in a short amount of time. Eight skilled female modern dancers were instructed to drop jump onto a force platform with both legs from four different heights(15,30,45,60cm). They were filmed from the side with a high speed camera (100fps). The power developed at the ankle, the knee and hip joints was computed by multiplying the moment of force by the joint angular velocity. Mechanical energy was absorbed by the eccentric contraction of the ankle and knee joint muscles during phase of downward movement. Mechanical energy absorption rate by eccentric contraction related to the knee joint muscle at high load intensity was relativly higher than low load intensity. It required the energy absorption by the eccentric contraction of knee joint muscles in order to reduce take off time in phase of downward movement. In push off phase, it projected the body into the air by the concentric contraction of ankle and knee joint muscles.

Counter-Movement Drop Jumping에 있어 落下높이의 影響
裵永相,裵正幸 啓明大學校 生活科學硏究所 1995 科學論集 Vol.21 No.-
The purpose of this study was to examin changes in mechanical power generation at each joint of lower limb during the counter-movement drop jumping at different heights. Eight skilled female dancers were instructed so as to drop jumping on a force platform with their both legs at four different heights (15, 30, 45, 60cm). They were filmed from side with a high speed camera (100fps). The power developed at the ankle, the knee and the hip joint were computed by taking the product of moment of force and joint angular velocity. The mechanical power generated at the knee joint during the counter-movement drop jumping was somewhat larger than that at the ankle and hip joint. The knee extensors and the ankle plantarflexors were the dominant muscle grop during the downward and push-off phase of drop jumping. And the hip extensors were the dominant muscle grop from 10% of the elapsed time to 90% of that. The mechanical work of the hip extensors was observed to increase with dropping height, and the highest mechanical work of hip extensors was found during dropping height of 0.60m. The energy which was produced by a concentric contraction of the knee extensors and the ankle plantarflexors during the push-off phase of the drop jumping was used to extend the ankle and knee and to drive the body upward for the high jump.

한국 근대사에 있어서 체육에 관한 연구(Ⅱ) : 해방 직후 과도기의 학교체육을 중심으로
이달원,배정행 啓明專門大學 産業開發硏究所 2002 啓明硏究論叢 Vol.20 No.1
본 연구는 해방 직후 과도기 교육과정 속의 체육을 살펴보고자 하였다. 해방 직후 우리나라는 혼란 속에서도 우리 민족선각자들의 민족주의 교육열망과 민주주의에 의한 미군정의 서구적 의식에 의하여 체육이 표면적 발전을 이를 수 있었다. 그러나 당시의 불안정한 시대적 상황과 첨예한 이념의 대치 속에서 그 가치는 혼미를 거듭하였던 것이다. 따라서 현대 체육교육이 바로 서기 위해서는 교육에 대한 완벽한 준비와 교육 본연의 의미를 희석시키는 모든 상황과는 단절할 수 있는 교육의 독립성을 유지하여야 한다는 것이다. This research focuses on physical education of school during the time of transition after liberation. Enthusiasm of old scholar and influence from USA educational pattern, Physical education acquired superficial development. However. Value of physical education under social disorder and ideology conflict were not fully assessed, Preparation and Isolation of education itself are critical to realize true meaning or thought of physical education.
