The purpose of this study was to analyze the comparisons of the kinematical variables when performing Yoko Ukemi(side breakfall) by three Stage in Judo. The subjects were four male judokas who were trainees Y. I. University Squad members and the Yoko Ukemi were filmed by two S-VHS 16mm video cameras(60fields/sec.). The selected times were subject to KWON 3D analysis program and kinematical analysis to compare variables of three Yoko Ukemi. Temporal variables(total time-required : TK, TR by each phase), the body part touched order on the mat and COG variables were computed through video analysis while performing right Yoko Ukemi by three stage. From the data analysis and discussion, the following conclusions were drawn : 1. Temporal variables : total time-required(TR) when performing Yoko Ukemi(side breakfall) by each stage, the first stage(full squat posture: FP : 1.11sec.) showed the shortest time, the next was 3rd(Shizenhontai, straight natural posture: NP : 1.41sec.), and 2nd(Jigohontai, straight defensive posture, DP : 1.42sec.), respectively- 2. TR when performing Yoko Ukemi(side breakfall) by each stage, and phase : the first phase(take of phase, average 0.68sec.) showed the longest time, next was the third phase(ukemi phase, 0.39sec.), and the second phase(air phase, 0.23sec.), respectively. 3. When performing yore Ukemi the body part touched order and TR on the mat : hip(0.94sec.) showed the shortest time, the next was elbow hand(0.97sec.), back(0.98sec.), and shoulder(1.04sec.) order. The hip part touched on the mat the first, but slap the mat in order to alleviate the shock try hand palm and forearm before receiving impact (difference 0.03sec,) 4. Vertical COG variables in each event by each stage : e1(ready position, average 78.33cm) moved the highest, the next was e2(jumping position, 70.14cm), e3(transition position, average 64.00cm), e4(landing position, average 35.99cm), and e5(ukemi position, average 18.32cm) order, gradual decrease respectively. And the difference of COG were showed in initial by each stage, because position fo Yoko Ukemi was difference by each stage in preparation position, but in accordance with executing of Ukemi phase that difference of COG was by decreasing, almost equal displacement in e4(landing) and e5(Ukemi)position finally.

본 연구는 근대5종 세계대회 데이터베이스에서 2015년부터 총 5년간의 공식 세계기록을 수집하여 사격 유형 및 특성이 기록에 미치는 영향을 밝혀내고자 했다. 이를 위해 UIPM Level 1 대회인 월드컵, 세계선수권대회 출전한 남녀 모든 선수에 대해 전체 사격 격발 경우를 분석하였다. 연구결과 왕복횟수와 차수가 늘어날수록 사격누적기록이 나빠지는 양상을 보였고, 1번째 왕복 3차 사격에서 가장 좋은 기록을, 4번째 왕복 5차 사격에서 가장 나쁜 기록이 나타났다. 또한, 첫발의 성공 유무에 따른 누적사격기록 편차 값은 왕복횟수가 늘어남에 따라 9%가량 편차가 증가하는 경향성이 나타났는데 이는 시간이 지남에 따라 첫발의 성공은 더욱 중요하며 근대5종 사격 시 첫발 명중만으로 기록단축에 큰 효과를 거둘 수 있다. 이러한 연구를 바탕으로 사격 정확성에 영향을 미치는 요인 및 특징을 밝히고, 복합경기 특성에 맞게 육상기록과 연계한 후속 연구가 필요하다고 사료된다.

The purpose of this study was to investigate the height of jump, angle of the ankle and knee, the angular velocity of the ankle and knee between two types of ballet shoes during a jump in the 1st position. The subjects were 5 female ballet majors of university in Busan the majors who have been dancing ballet for six years on the average. The conclusions are as follows: 1. The height of jump had no significant difference between two types of ballet shoes, and then the average of the height of jump with point shoes group ($20.24{\pm}4.62\;cm$) was a little higher than ballet shoes group ($17.50{\pm}4.05\;cm$). 2. The angle of the ankle had no significant difference for all events between two types of ballet shoes. The minimum angle of ankle joint was represented to $54.36_{\circ}$ at the E1 of the left ankle angle of the ballet shoes and the maximum value was showed $155.43_{\circ}$ at the E3 of the right ankle angle of the point shoes. 3. The angle of the knee had no significant difference for all events between two types of ballet shoes. The minimum angle of knee joint was represented to $99.54_{\circ}$ at the E1 of the left knee angle of the ballet shoes and the maximum value was showed $174.25_{\circ}$ at the E3 of the right knee angle of the point shoes. 4. The ankle velocity of the ankle had no significant difference for all events between two types of ballet shoes. The minimum angular velocity of the ankle was represented to 4.35 deg/s at the maximum height(E3) of the point shoes and the maximum value was showed 597.81 deg/s at the take-off(E2) of the right ankle angle of the point shoes. 5. The angular velocity of the knee had significant difference between two types of ballet shoes at the event 1(p<.05). The minimum angular velocity of the hee was represented to -1.68 deg/s at the maximum height(E3) of the point shoes and the maximum value was showed 360.25 deg/s at the take-off(E2) of the left knee angle of the ballet shoes. The other events had no significant difference between two types of ballet shoes.

The purpose of this study was to compare muscle activity in the lower extremity during walking wearing jogging and roller shoes. Twelve male middle school students (age: 15.0 yrs, height 173.7 cm, weight 587.7 N) who have no known musculoskeletal disorders were recruited as the subjects. Seven pairs of surface electrodes (QEMG8, Laxtha Korea, gain = 1,000, input impedance >$1012{\Omega}$, CMMR >100 dB) were attached to the right-hand side of the body to monitor the rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), tibialis anterior (TA), and medial (GM) and lateral gastrocnemius (GL) while subjects walked wearing roller and jogging shoes in random order at a speed of 1.1 m/s. An event sync unit with a bright LED light was used to synchronize the video and EMG recordings. EMG data were filtered using a 10 Hz to 350 Hz Butterworth band-passdigital filter and further normalized to the respective maximum voluntary isometric contraction EMG levels. For each trial being analyzed, five critical instants and four phases were identified from the recording. Averaged IEMG and peak IEMG were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between shoe conditions (p<.05). The VM, TA, BF, and GM activities during the initial double limb stance and the initial single limb stance reduced significantly when going from jogging shoe to roller shoe condition. The decrease in EMG levels in those muscles indicated that the subjects locked the ankle and knee joints in an awkward fashion to compensate for the imbalance. Muscle activity in the GM for the roller shoe condition was significantly greater than the corresponding value for the jogging shoe condition during the terminal double limb stance and the terminal single limb stance. Because the subjects tried to keep their upper body weight in front of the hip to prevent falling backward, the GM activity for the roller shoe condition increased. It seems that there are differences in muscle activity between roller shoe and jogging shoe conditions. The differences in EMG pattern may be caused primarily by the altered position of ankle, knee, and center of mass throughout the walking cycle. Future studies should examine joint kinematics during walking with roller shoes.

본 연구는 세계적인 경쟁력을 보유하고 있는 철봉종목의 국가대표 K선수를 대상으로 기술분석을 통해 고난도 기술인 Tkatrhev skekhed 동작의 완성도를 높임으로서 경기력 향상에 도움을 주고자 수행하였다. 이를 위하여 Tkatchev stretched 동작의 1차 분석을 통해 기술훈련방법의 피드백을 8주간 제공 한 후 반복적인 분석을 통해 기술의 완성도를 평가하였다. K선수의 1차 Tkatchev stretched 동작은 비행높이가 낮고, 비행 중 신체가 굴곡되어 있으며, 봉잡기 시 신체중심의 위치가 바로 부터 너무 멀고 낮아 낙히의 염려가 있을 뿐만 아니라 후속기술을 위한 역동성을 기대하기가 어려운 단점이 노출되었다. 이 같은 단점을 극복하기 위하여 준비국면인 크게 휘돌기의 하강 시 견관절 각을 빠르게 신전시키고, 고관절의 각운동을 이용한 Tap 동작을 짧고 간결하게 하게 하였다. 또한 몸을 접어주는 Tap 타이밍을 조금 늦추며, 다리를 차내며 신체를 역회전시킬 때 견관절의 각운동을 크게 사용하면서 신체를 충분히 끌어 올리는 연습을 주 5회(오전/오후) 총 7시간의 연습 시간 중 20분씩 8주간(총 800분)을 반복적으로 실시하였다. 그 결과 비록 봉 이탈 순간 수직상승속도의 증가를 이루지는 못하였지만 비행높이가 증가되어 고관절을 신전시키고도 철봉에 다리가 걸리지 않으며 뛰어넘을 수 있게 되어 동작의 웅대함을 제공함으로서 감점요소를 0.2점 제거할 수 있었다.
