높이뛰기 동작시 발 구름구간에서의 인체 각운동량 분석

Analysis of Angular Momentum in touch-down phase at Fosbury Flop High Jump Motion

&nbsp;&nbsp;높이뛰기 선수들의 3차원 영상분석을 통한 각운동량 요인들을 비교 분석한 결과는 다음과 같다.<BR>&nbsp;&nbsp;하지의 각운동량에서는 인체 무게중심을 상승시키는데 도움이 되는 추진다리의 각운동량이 그다지 크지 않게 관찰되고, 상지의 동작에서도 바에 가까운 팔의 각운동량만 크게 나타남으로서, 인체 무게중심을 상승하는데 필요한 양팔 동작이 필요한 것으로 사료된다.

&nbsp;&nbsp;This study is to investigate the Angular Momentum of Fosbury flop high jump&quot;s athletes through the analysis of 3-D motion, and then also is to compare Fosbury flop high jump&quot;s athletes with Angular Momentum factors. The results of this study are as follows:<BR>&nbsp;&nbsp;Angular momentum of lead legs was found to be low in a few athletes arms in order to increase CG position, but that of near arms was found to be high in upper arm&quot;s motion. While both the arms were not used in the motion of arms in order to increase CG position, only one arm was found to be used.
