초록

이 연구는 요가 수련 그룹 7명과 비수련 그룹 7명을 대상으로 눈뜨고 눈감고 외발서기 시 COP 95% confidence ellipse area를 이용하여 균형 제어 능력을 평가하는데 그 목적이 있다. 요가 수련 그룹이 눈뜨고 눈감고 외발서기 모두에서 COP 전후 좌우 표준편차와 COP 95% confidence ellipse area가 비수련 그룹보다 유의하게 작게 나타나 요가 수련이 균형 제어 능력 개선에 영향을 미치는 것으로 나타났다. 요가 수련 그룹 내에서는 COP 전후 좌우 표준편차와 COP 95% confidence ellipse area 모두에서 눈뜨고 외발서기가 눈감고 외발서기보다 작게 나타나 시각이 균형 제어 능력에 영향을 미치는 것으로 나타났다. COP 95% confidence ellipse area는 균형 제어 능력 평가 시 분별력이 높은 변수로 생각되며, 차후 다양한 그룹과 많은 대상자를 이용하여 다른 변수들 간의 비교 분석을 통한 추가 연구가 기대된다.

The purpose of this study was to investigate of assessment of the ability of balance control using COP 95% confidence ellipse area while executing single-leg stance with eyes open and eyes closed through GRF system. The subjects participated in this study were 7 female yoga group and 7 female control group. The yoga training affected to improve the ability of balance control because the yoga group's COP AP and ML standard deviation and COP 95% confidence ellipse area were smaller than control group in both a single-leg stance with eyes open and eyes closed. Visual affected to the ability of balance control in a single-leg stance. I consider COP 95% confidence ellipse area as a high variable for determining the ability of balance control, and therefore suggest that additional studies for various groups and subjects will be required in the future.
