댄스스포츠 쿠카라차 스텝 시 팔동작 유·무에 따른 지면반력 연구 = A Study for Ground Reaction Force with Arm Motion and with No Arm Motion at Dance Sport Cucarachas Step

다국어 초록 (Multilingual Abstract)

The purpose of this study is to analysis ground reaction force with arm motion and with no arm motion at dance sport cucarachas step and to inquire effectiveness about the balancing of body in examination, then to provide quantitative informations to coaches and players.
Seven female Subjects who had experienced winning a prize career form national and domestic amateur contest It is consisted of one force plate(U.S.A. AMTI 3778).
Ground reaction force is established right and left direction at X axis(force at Fx), anterior and posterior direction at Y axis(force at Fy) and superior and inferior direction at Z. axis(force at Fz).
It is calculated means and standard deviations for forces in motion and no-motion by using SPSS statistical analysis software(9.0 versions). T-test(significance level: p ＜0.05) is performed in order to get an effective method in arm motion and in no arm motion at dance sport cucarachas step.
The results of this study are as follows: Breaking force show significant arm in motion and no-motion .017(p＜.05) ground reaction force Fx, but driving force did not show significant.
It is shown the difference to variation of posterior ground reaction force with arm motion and with no arm motion.001(p ＜.001), whereas it is not shown the difference statistically about anterior ground reaction force with arm motion and with no arm motion
On the other hand, it is not shown the difference statistically about vertical ground reaction force Fz in this study.
It is considered that the significant difference between a breaking force and a posterior ground reaction force is due to move a center of gravity by arm in motion using B. foot inside edge and a ball of foot reaction force.
