아동의 오버 암 던지기 동작이 투사 거리에 미치는 영향

배성제 한국초등체육학회 2008 한국초등체육학회지 Vol.14 No.1

던지기 경기의 기록은 신체의 구조적, 체력적, 기술적 요인 등에 의해 결정되므로 신체 구조적 조건과 체력적 조건이 우수한 것만으로는 최고의 기록에 도달할 수 없다. 따라서 주어진 체격과 체력을 이용하여 던지기 기록을 극대화하기 위해서는 신체의 구조적, 체력적 요인이 우수해야 함은 물론 던지기의 전체적인 과정에서 효율적인 동작을 구사하는 기술적 요인이 중요하다(배성제, 1994). 물체를 멀리 또는 목표물에 정확하게 던지는 동작은 일상생활, 산업 활동, 체육 및 스포츠 활동 등에서 중요한 운동 요소 중에 하나이다. 특히, 던지기 동작

This study was designed to evaluate the pain characteristics of tension-type headache by the tongue ridge. Patients with tension-type headache visited the Department of Oral Medicine, K University Dental Hospital were recruited to this study. Experimental group(n=65) was composed of tension-type headache with the tongue ridge and control group(n=65) was composed of tension-type headache without the tongue ridge. Evaluation list was pain quality, pain intensity, pain laterality, pain increase by routine physical activity and then it was analyzed statistically. The results were as follows: 1. Pain quality of tension-type headache patient was significantly different by the tongue ridge(p=0.049). 2. Pain intensity of tension-type headache patient was significantly different by the tongue ridge(p=0.010). 3. Pain laterality of tension-type headache patient was not significantly different by the tongue ridge. 4. Pain increase by routine physical activity of tension-type headache patient was not significantly different by the tongue ridge. Therefore, it was considered that the tension-type headache patient was influenced by the tongue ridge in the pain quality and pain intensity.

배성제 경인교육대학교 교육연구원 2018 교육논총 Vol.38 No.1

본 연구는 남자 시각장애 아동의 보행특성 및 경향성을 분석하는 연구가 아닌 일정기간 동안의 보 행과 관련된 신체적인 학습과 훈련을 통한 보행 동작의 Kinematic변인 변화를 분석하는 종단적 연구이다.본 연구의 목적은 시각 장애 남자 초등학교 아동을 대상으로 12주간의 걷기 연습 및 관 련 트레이닝을 통하여 시각장애 아동의 보행 동작이 어떻게 학습되어지고 운동역학적으로 어떠한 변화를 유도하는 지를 분석하고자 수행되었다.이러한 연구 목적을 달성하기 위하여 보행 속도,신 체중심의 상대 수직 및 좌우 이동 거리,걸음 주기 시간,신체 전․후경각,무릎관절각,발목 관절 각,고관절각,발회전각,발회선각,하퇴 중심의 및 발끝의 각속도 등의 변인을 분석하였다.본 연 구의 결과를 통해서 시각장애 아동의 걷기 연습 전·후의 보행 동작의 Kinematic요인 변화를 이해 할 수 있으며,또한 다양한 Kinematic요인 변화를 통해 초등학교 남자 시각장애 아동의 보행 동작 의 정확한 진단과 평가를 위한 기초 자료로 이용될 수 있을 것이다.특히,본 연구 결과로 나타난 정량적인 보행 역학에 관련된 자료는 시각장애 아동 보행 동작의 효율성을 제고하고 일상생활에서 보행 동작을 지속적인 피드백을 받으면서 보행동작의 학습효과를 극대화시키는데 도움을 줄 것으 로 판단된다. The aims of this study was to investigate the change of visually impaired elementary male students s gait motion after a 12-week-long training program. The kinematic variables examined in this study include gait velocity, the center of gravity height change, stride time, stride length, body lean angle, knee joint angle, ankle joint angle, foot rotation angle, shank and toe angular velocity. The subjects were 13 visually impaired elementary students. Each student’s performances was recorded using two high speed cameras at the speed of 100 frames per second. DLT(Direct Linear Transformation technique) was applied to data collection and video analysis. The positions of body landmarks in the projected images were digitalized for every frame of the two cameras. Subsequently, the cubic spline functions were used to compute interpolated values for the instants that corresponded in time. Main findings are as follows: 1. There was an increase in velocity of the center of gravity at the left foot landing and at the right foot takeoff after the training program. 2. There was an increase in the stride length, but a decrease in the stride time after the training program. 3. There were increases in the knee joint angle range and ankle joint angle range, foot rotation angle flexion range from the left foot landing to the right foot takeoff after the training program. 4. There were increases in the shank and toe angular velocity at the left foot landing and at the right foot takeoff after the training program. Therefore, there arose a need to develop a model of gait patterns for visually impaired children, based on their gait characteristics. It is also necessary to apply the findings of this study to the development of an adapted physical education program model and help visually impaired children acquire efficient gait patterns.

This study was conducted to investigate relationship between the angular momentum of the long jump takeoff phase and flight distance performed by elite athletes. Eight male athletes who achieved at least the 3rd place in the long jump at the Korea National Track and Field meetings during 1993 and 1994 were selected as subjects. The long jump motions performed by the subjects were recorded using two 16mm high speed cameras at the nominal speed of 100 frames per second. The Direct Linear Transformation technique was adopted from the beginning of filming to the final stage of data extraction. The movement patterns during the last stride for run-up, takeoff, and the flight distance were related using regressional method with the biomechanical consideration. It was found that: The mean shank angular velocity at the instant of takeoff was -4.96±2.48rad/s, regression equation of flight distance (Y) prediction was Y=-0.1055·(shank angular velocity)+6.2916 (r=0.63, P<0.0001). The mean tatal relative angular momentum (absoute angular momentum/subject's mass·height²) with respect to a transverse axis through the center of gravity at the instant of touchdown was -0.134±0.050, regression equation of flight distance (Y) prediction was Y=-0.1055·(tatal relative angular momentum)+6.5971 (r=0.64, P<0.0001). And The mean tatal relative angular momentum with respect to a transverse axis through the center of gravity at the instant of takeoff was -0.424±0.117, regression equation of flight distance (Y) prediction was Y=2.1304·(tatal relative angular momentum)²+6.4182 (r=0.62, P<0.0001). Therefore, in order to increase flight distance, several conditions must be fulfilled at the instant of takeoff leg touchdown and takeoff during takeoff phase. First, the active landing style described as clawing the ground with the sole of the takeoff foot should be performed during the takeoff leg touchdown and takeoff. Second, the total forward angular momentum with respect to a transverse axis through the center of gravity should be increased during the takeoff leg touchdown and takeoff.

This study was conducted to investigate the running motion in the 3, 4, 5 m/sec running velocity by performed elementary school athletes. Ten elementary school male athletes who achieved at least the 3rd place in the sprint at the Korea Gangwon-Do elementary school track and field meetings were selected as subjects. The running motions performed by the subjects were recorded using two 8mm cameras at the nominal speed of 90 frames per second. The Direct Linear Transformation technique was adopted from the beginning of filming to the final stage of data extraction. KWON 3D motion analysis package program was used to compute the 3 Dimensional coordinates, smoothing factor in which the lowpass filtering method was used and cutoff frequency was 6.0 Hz. The movement patterns during foot touchdown and takeoff for the running stride were related with the biomechanical consideration. Within the limitations of this study it is concluded:First, as the velocity increase, the body C.O.G(Center of Gravity) height should be raised at the instant of leg touchdown and takeoff during the running. As increase running velocity, while taking a slightly greater body lean angle within the range of the subject's running motion during at touchdown and takeoff phase would reult in greater flight distance. Second, as the velocity increase, the foot contact time should be shortened during the running. Third, as the velocity increase, the angular velocity of foot joint torsion increase. The angular velocity of foot joint torsion of the higher running velocity is larger than that of other running velocity at touchdown and takeoff phase. In order to get rid of the joint injuries, as the velocity increase, the supination must be increased. And, as the velocity increase, the angular velocity of Achilles tendon increase at the touchdown and takeoff phase. Because the increasing velocity make up ankle ligament injuries, We need to thicken the portion of the metatarsal a litter bit when the running shoes. Forth, as the velocity increase, the angular velocity of foot joint increase at touch-down and take-off phase. Also, as the velocity increase, the shank angular velocity with respect to a transverse axis through the center of gravity should be increased during the leg touchdown and takeoff. Therefore, the active landing style described as clawing the ground with the sole of the foot should be performed during the leg touchdown and takeoff phase.
