도마 Yurchenko 몸 펴 공중돌기 동작의 운동학적 분석 = The Kinematical Analysis of Yurchenko Stretched at Horse Vaulting

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate effects of kinematical variables performed from Yurchenko Stretched skill in horse vaulting. Four national woman gymnasts participated in this study, and four PD-150 video cameras were used to capture motions for three dimensional analysis. The conclusions are as followings: The CoG height of S2 is higher than S1 in post flight phase by means of increasing horizontal velocity at touching board and vertical velocity at taking off board. Those make stable landing postures. The rapid horizontal velocity of S4 both at peak and at landing make unstable landing postures. The vertical velocity of S2 (2.28 ㎧) is much faster than that of S4 (1.36 ㎧) when they take off board. That is an important factor that decides successful motions. Also CoG of S4 is low as she moves to forward direction with scapular angle of S4 not full extending. S1 and S4 have pertinent blockings doing arm into flexion and extension compared to S2 and S3.Trunk angles of S1 and S4 at taking off board are greater than S2 and S3. That make their bodies approaching the horse too closely, and then they can't control themselves. Therefore, they can't move vertical motions. At touching down board, S1 and S4 contacted board with knee joint angle moving flexion, and at taking off board, they take off the board with knee joint angle moving extension. But, S1 suffers difficulty on vertical rise motion because S1 don't extend knee joint completely compared to other subjects.
