Eun, S-D. The effect of the stair heights on lower extremity joint moment in stair-ascent activity. Korean Journal of Sport Biomechanics, Vol. 13, No. 1, pp. 121-138. The purpose of this study was to investigate the effect of the stair heights on lower extremity joint moment in stair-ascent activity. Data were collected by 3-D cinematography, force platform. six normal males were participated in this experiment. All subjects performed a stair-ascent in four different heights of stairs (10, 14, 18, 22cm) having a 5 step staircase. The moment of lower extremity joint was analyzed during stance phase. The results were as follows: First, the second increase of plantar flexion moment of ankle joint in the 'forward continuance' phase was not occurred for stair A and B. But it occurred for stair C and D. And the maximum plantar flexion moment increased as the stair height become higher. Second, it was shown that the maximum inversion moment of the ankle joint was the smallest at stair B and it increased significantly at stair C. Third, maximum extension moment appeared in the 'pull-up' phase. And it increased as the stair height become higher. Fourth, it was shown that the maximum abduction moment of the knee joint was the smallest at stair C and it increased significantly at stair C. Fifth, maximum extension moment of hip joint increased significantly at stair C. Sixth, remarkable value of adduction moment occurred at hip joints and maximum adduction moment increased at stair D.

은선덕 서울대학교 체육연구소 2001 서울大學校 體育硏究所論集 Vol.22 No.1

The purpose of this study was to investigate the effect of speed conditions on the gait pattern in old age. Data were collected using video camera and video analyzing system. Six males in their sixty to seventies were tested during slow(3.5km/h), moderate(4.0km/h), fast(4.5km/h) speed on treadmill wish 10% grade. They were videotaped using a high speed video camera with the frame rate being 60Hz, Variables computated using the method of two-dimensional video analysis. One-way ANOVA was used to evaluating the statistical significance. The results obtained from this study were as follows: The stance phase was increased and swing phase was decreased as the speed uras increased in all subjects. But there was no significant difference statistically. All subjects did not show a significant difference in speed conditions at major events jn mean ankle angle. However, max. ankle angle and ROM(range of motion) during stance phase was augmented as the speed was increased(P<.05). All subjects did not show a significant difference in speed conditions at major event in mean knee angle. However min. ankle angle during stance phase and ROM during swing phase was augmented as the speed was increased(P<.05).

은선덕,정철수,배성제 한국운동역학회 1996 한국운동역학회지 Vol.6 No.1

본 연구의 목적은 100m 달리기에서 최고 속도 구간과 감속 구간에서의 동작을 비교하여 감속의 원인을 규명하는 데 있다. 두 구간에 대한 주요 운동학적 변인인 신체 중심의 속도와 변위, 보속과 보폭, 상체의 전경각, 관절각, 각속도를 분석하여 다음과 같은 결론은 얻었다. 감속 구간에서의 지면 접촉 기간 동안과 체공 기간 동안의 신체 중심의 수평 속도는 최고 속도 구간에 비해 느린 것으로 나타났다. 보속은 최고 속도 구간에 비해 느린 것으로 나타났고, 지지 시간은 긴 것으로 나타났으며, 체공 시간은 차이가 나타나지 않았다. 보폭은 최고 속도 구간에 비해 짧은 것으로 나타났고, 착지시 신체 중심과 발끝의 수평 거리는 최고 속도 구간에 비해 긴 것으로 나타났다. 또한 상체의 전경각은 착지시에만 차이가 있었으며 최고 속도 구간에 비해 작고, 무릎 관절각은 착지시와 이지시에 있어서 최고 속도 구간에 비해 작았다. 그리고 고관절각은 반대발의 이지시와 착지시, 그리고 최소값에 있어서 최고 속도 구간에 비해 크고, 운동 범위에 있어서는 작은 것으로 나타났다. 또한 무릎 관절 각속도는 최고 속도 구간과의 비교에서 차이가 나타나지 않았다. The study was conducted to make a comparative analysis of running motion and to examine the difference in the deceleration phase(80∼90m) and the Max-speed phase(30∼40m) during the 100-meter Sprint. In this study, data was analyzed with variables including velocity and displacement of center of gravity, stride frequency, stride length, foward angle of upper body, joint angle, angular velocity in the deceleration phase and the max-speed phase. The conclusions of the study were as follows ; 1. Horizontal velocity of the center of gravity in the deceleration phase was found to be slower than that in the max-speed phase in the supporting period and non-supporting period. 2. Stride frequency in the deceleration phase was found to be slower than that in the max-speed phase, and supporting time n the deceleration phase was longer than that in the max-speed phase, also there was no difference between each phase in nonsupporting time. 3. Stride length in the deceleration phase was to be found shorter than that in the max-speed phase. 4. Horizontal distance between the center of gravity and toe in the deceleration phase was to be found longer than that in the max-speed phase. 5. Forward angle of upper body at the moment of touch down in the deceleration phase was found to be smaller than that in the max-speed phase. 6. Knee angle at the moment of touch down and take off in the deceleration phase were found to be smaller than in the max-speed phase. 7. Hip angle at the moment of touch down and take off of the other foot, and minimum hip angle in the deceleration phase were found to be larger than that in the max-speed phase, and range of, motion in the deceleration phase was smaller than that in the max-speed phase. 8. Knee angular velocity at the moment of touch down of the other foot toward flection in the deceleration phase was found to be larger than that in the max-speed phase.

운동역학 : 노인의 계단 오르기 활동시 보행 패턴에 미치는 계단 높이의 효과

은선덕(SeonDeokEun),이기광(KiKwangLee) 한국체육학회 2004 한국체육학회지 Vol.43 No.6

The purpose of this study was to investigate the effect of the stair heights on the gait pattern in stair-ascent activity of elderly persons. Data were collected by 3-D cinematography and EMG. Eight male elderly persons were participated in this experiment. All subjects performed a stair-ascent in four different heights of stairs (10, 14, 18, 22cm) having 5 steps each. The changes of lower extremity angles and IEMG were analyzed during stance phase. The results on the stair-ascent activity of elderly persons were as follows: First, it was observed that the maximum extension angle of ankle joint increased significantly at stair C (18cm). In case of `pull-up` phase, however, extension angle decreased evidently at stair C Second, the maximum extension of knee joint occurred around the 65% of stance phase for stair A (10cm) and stair B (14cm), while it occurred in the `forward continuance` phase over 80% of stance phase for stair C and stair D(22cm). Third, as for IEMG, there was no significant change caused by stair height, at the stair C, however, the EMG activity of biceps femoris was very high. The IEMG of Soleus at stair B was greater than that at stair A.
