복근과 배근력 강화훈련을 통한 복/배근력의 균형비 변화가 역도 인상기술에 미치는 영향 = The effect of balance rate variation on snatch technique through Abdominal/Back muscle training

다국어 초록 (Multilingual Abstract)

The Purpose of this study was to investigate snatch technique enhancement effect by 5 months ABS & Back training. We analysed Korea elite weightlifting championship in June, 2003 before ABS & Back training and analysed Korea weightlifting competetion in October, 2003 after ABS/Back training. They are videotaped on digital camera with the frame rate being 30Hz. This data was reduced to 2D coordinates using 2D DLT method. It was conclusions that; ① The balance rate of Abdominal muscles/Back muscle enhanced 14-53% by 5 months ABS/Back training for four subjects. ② Subject A, B, D reduced pull phase time, also movement distance reduce in start phase, pull phase, lock out phase. ③ Subject C reduced maximal velocity in pull phase, and movement distance reduce in start phase, pull phase, lock out phase. ④ Pull phase time reduced by ABS/Back trainning. and reduce barbell movement distance about 3-15cm for four subjects.
