룸바의 WALK 동작에 대한 근전도 분석

Abstract

This study aims to analyze the electromyography on the 3 walking motions(checked forward walk, delayed walk, forward walk turning) of the latin dance, rumba. To answer the question, we measured the electromyography of the dancers who graduated P art college and specialized in latin dance. These dancers group consist of 5 professional dancers who have played for more than 3 years, and 5 amateur dancers played less than 1 year. The result of this study were as follows; 1. The integral electromyography (1) In the case of the checked forward, the result of the professional group is higher than the one of the amateur group on the electromyography of tibialis anterior and gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of rectus femoris and vastus medialis(p＜ .01). (2) In the case of the delayed walk, the result of the professional group is higher than the one of the amateur group on the electromyography of tibialis anterior and gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of rectus femoris and vastus medialis(p＜ .01). (3) In the case of the forward walk turning , the result of the professional group is statistically higher than the one of the amateur group on the electromyography of tibialis anterior, gastrocnemius, rectus femoris and vastus medialis(p＜ .01). 2. Peak of the electromyography (1) In the case of the checked forward, the result of the professional group is higher than the one of the amateur group on the electromyography of rectus femoris and gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of tibialis anterior and vastus medialis(p＜ .01). (2) In the case of the delayed walk, the result of the professional group is higher than the one of the amateur group on the electromyography of rectus femoris and gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of tibialis anterior and vastus medialis(p＜ .01). (3) In the case of the forward walk turning , the result of the professional group is higher than the one of the amateur group on the electromyography of gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of tibialis anterior, rectus femoris and vastus medialis(p＜ .05). 3.Average of the electromyography (1) In the case of the checked forward, the result of the professional group is higher than the one of the amateur group on the electromyography of tibialis anterior and gastrocnemius. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of rectus femoris and vastus medialis(p＜ .01). (2) In the case of the delayed walk, the result of the professional group is higher than the one of the amateur group on the electromyography of tibialis anterior and 비복근. There is no statistical difference. The result of the professional group is statistically higher than the one of the amateur group on the electromyography of rectus femoris and vastus medialis(p＜ .01). (3) In the case of the forward walk turning , the result of the professional group is statistically higher than the one of the amateur group on the electromyography of tibialis anterior, gastrocnemius, rectus femoris and vastus medialis(p＜ .05).
