유도 전방회전낙법 동작의 키네메틱 분석 = A Kinematic analysis of Mae mawari ukemi(forward rolling breakfall) in judo

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze kinematic variable at the time of Judo obstacle forward rolling breakfall. To do so, three dimensional kinematic variable at the time of Judo forward rolling breakfall motions was calculated on five model males of Y university, and, time C. O. G. variable were established. That was standardized using cubic spline interpolation based on the maximum motions time by calculating average value and standard deviation per each factor. As a result of this analysis, I reached following conclusion.
1. Time variable
At the time of Judo forward rolling breakfall motions, the total required time was 0.93 seconds, and to describe per phase: at the second phase, air phase, 0.50 seconds(54%): at the third phase, completion phase, 0.36 seconds(38%); and the first phase, take-off phase, 0.08(8%) seconds.
2. C. O. G. variable
Left(0.01m)·front(0.26m)·up(0.13m) moved at take-off phase, and left(0.09m)·front(1.46m)·up(0.32m) moved at air phase, and left(0.15m)·front(3.79m)·down(0.71m) moved at breakfall phase.
In conclusion, all the subjects conducted bending and stretching exercise and made the center move for jumping higher at take-off phase, assumed motions to keep balance at air phase, and assumed motions for widening base surface by lowering the center and extending the joint of the knee to reduce an impact and assume stable posture at breakfall phase.
