Abstract

이 연구는 20대 여대생들을 대상으로 세 가지 균형조절 훈련(Aqua, Bio-feedback, Trampolin)이 정적 균형 능력과 시각, 전정각, 고유수용감각 등의 감각요소에 미치는 효과를 비교하기 위해 아쿠아 훈련군(10명), 바이오피드백 훈련군(10명), 트램폴린 훈련군(9명)으로 무작위 할당한 후 각 군별로 주 3회, 회당 30분간의 운동 프로그램을 6주간 진행하면서 3주후, 6주후에 Tetrax portable multiple system을 이용하여 안정성지수를 측정하고, 근전도 중앙주파수값을 이용하여 산출한 근전도 균형점수를 반복측정된 자료의 분산분석 및 Wilcoxon의 부호순위 검정 등을 이용하여 비교 분석한 결과를 종합해 볼 때, 바이오피드백 훈련은 세 가지 감각기능을 고루 향상시키며 아울러 감각기능 간의 협응성 또한 향상시키는 것으로 판단되며, 아쿠아 훈련은 전정기능을 집중적으로 강화시키는 것으로 보인다. This study was conducted to compare the effect improving balance abilities of 3 balance training programs by randomized intervention trial. Study subjects were 29 female students recruited from a university in Gwanju, who allocated randomly to 3 intervention groups, aqua group(modified Halliwick 10 point program, N=10), visual bio-feedback balance training group(N=10), and balance-pad plus trampolin group(N=9). As the results of repeated musure ANOVA, Wilcoxon signed rank test, major research findings were as follows; 1. Regarding SI or BIEMG measured at upright posture on hard platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 2. Regarding SI or BIEMG measured at upright posture on soft platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 3. Regarding all 3 sensory ratios, bio-feedback group showed significantly higher increasement in them than other 2 groups. The results suggested that visual bio-feedback training program improve the all 3 sensory functions required for balancing, and aqua training modified from Halliwick 10 point program contribute to improve vestibular function principally.
