Objectives: This study was conducted to introduce the prevention programs for musculoskeletal disorders in one farming village. Methods: We visited the village hall 12 times and gave an education program 9 times to residents. At the beginning, the middle, and the end of the program, we evaluated musculoskeletal disorders by doctors, musculoskeletal pains using the visual analogue scale, muscular strengths and flexibilities and musculoskeletal functions using structured questionnaires. Results: Fifty seven residents participated in this program at least one time, 20 (35.1%) were males and 37 (64.9%) were females. The mean age of participants is 60.7 (±8.1). Forty three residents were evaluated by doctors at least one time. Thirty three residents were diagnosed to at least one musculoskeletal disease. The severity of pains of neck-shoulders, low backs, and leg-knees tended to decline while 3 tests went by and those of the 3rd test are less severe than the 1st test statistically significantly (p<0.05). Musculoskeletal functions were improved as tests went by but not differed statistically significantly. Muscular strengths and flexibilities were better in the 1st than the 3rd test statistically significantly (p<0.05). Conclusions: Despite the program were held in off-season for farmers and the number of participants are small, through the program, musculoskeletal pains and functions were improved and muscular strengths and flexibilities were strengthened. We think that the program needs to be held during the busy farming season as well as the off-season.

인희교 한국스포츠리서치 2005 한국 스포츠 리서치 Vol.16 No.2

The purpose of this Study is to kinematically analyse Wenson Push Up motion which is C degree in dynamic muscular strength group to understand proper motion by difficulty. improve players' technique and moreover help coaches to check and estimate motions. To achieve this purpose, 5 male players who hold the high rank in sports aerobics national conference were selected and third dimension image analysis method by 2 high-speed cameras was used. 1. Moving displacement of the body center was shown 0.79±0.15 in El of X-axis and removed 0.98±0.15 to fingertip direction in E2. In E3 and E4. it appeared by 1.03±0.13. It appeared by 0.84±0.03 in Y-axis El. and moved to lower direction by 0.55±0.07 in E3. It is considered that the lower was body moving displacement on X-axis. the stabler was performance of difficulty. 2. In E2, Angle of right elbow joint was 148.52±10.35, Angle of left elbow joint was 166.3±11.39. In E3. Angle of right elbow joint was 79.34±21.30. Angle of left elbow joint was 64.24± 12.80. When right leg is placed on right upper arm. angle of left elbow is smaller than that of right elbow. This means adjusting bodily symmetry to show stable motion made angle of left elbow smaller. 3. Angular variation of right coxa was the smallest by 29.84±3.95 in E2, and the angle grow bigger gradually by 36.94±2.55 and 39.96±3.37 in E2 and E3. It is considered that while doing push-up. performing the motion with keeping small angle by trained muscle can be recognized as correct motion. 4. The speed variation of right tiptoe was fast in Phasel and Phased. In Phase2 and Phase3 the speed was decreased because while doing push-up, the speed variation of right tiptoe was not shown. This means fast performance of right leg in Phasel and Phased can show accuracy of the difficulty and size of the motion. Performing highly difficult motion in sports aerobic needs more trained muscular strength and flexibility. To make players perform accurate motion without any injury by systematical training, scientific study on ground reaction force and electromyogram is needed.

The purpose of this study was to analyze kinematics variables on basic information for the improving the skill of balance attitude with understanding principle and development of balance attitude. For this study, national champion skilled 4 female rhythmic sport gymnastics were selected as subjects, and 3-demensional coordinates computation was used to DLT(Direct Linear Transformation) method of Walton(1981). 1. As for each phase performance time, all subjects are mo difference from phase 1 to phase 3, but phase 4 must stop attitude almost 0.433sec like as JEJ, CYR. To phase 5, during right leg gather, performance time act 0.267sec like as JEJ. 2. To displacement of COP, phase 1 is resulted lowest, and in phase 2, phase 3, phase 4 order to be high. And phase 5 is resulted again to be low. 3. To angle displacement of left heel , phase 1 is prepare position, and phase 2 is high, from phase 3 to phase 4 is resulted average 75.0. JEJ is resulted very ideal position to 85.5˚ 4. To angle displacement of right knee, phase 1 is prepare position, and phase 2 is resulted generally knee angle to be small, and phase 3 and phase 4 is resulted maximal extension to knee angle. CEJ is resulted ideal position from phase 2 to phase 5. To angle displacement of left knee, phase 1 is prepare position, and phase 2 is that support left leg and knee deep flexion during rising left leg to horizontal plane, phase 3 is extended maximal angle during maximal extension to knee angle of left support leg, phase 4 is decreased knee angle when right left is maximal rising and then resulted little power of supporting leg. But LNY is resulted very ideal left knee angle. 5. To displacement of hip joint angle, phase 1 is prepare position, and phase 2 is reduce angle during rising right leg to horizontal plane as hop joint is resulted by complex. When knee angle of left support leg is maximal extension to phase 3 and right leg is rising maximal to phase 4, the grater this angle magnitude to hip joint and then physical position straightly resulted. CEJ is that phase 4 is resulted 116.6˚ 6. To right toe velocity, toe velocity is very fast during right leg is down. Phase 1 is prepare position, and phase 2 is fast toe velocity during rising right leg to horizontal plane, phase 3 and phase 4 is resulted stop attitude to slow toe velocity. To summarize above, for fast right foot performance, accurate stop attitude and hip joint little complex, I think that performed very ideal position and effective motion as a lot of flexibility exercise training.
