Abstract

The purpose of this study was to investigate the ability to maintain dynamic posturography(EquiTest) in gymnastic, freestyle skier, and figure skater. A total of 32 subjects(22 athletic woman and 10 collegiate woman) were participated in this study. Computerized dynamic posturography(EquiTest) was adopted to test sensory organization and motor control. EquiTest facilitated the quantification of the role of somatosensory, visual and vestibular systems in the maintenance of postural balance and was also pertinent to measure the reaction time to the stimulus to change center of gravity on force platform. As a result were as follow. There was not difference among with exercise group. But there was a significantly difference with between groups. It was suggested that the acrobatic and physical activity developed the function of visual system and the role of the combination of visual and vestibular system in maintaining postural balance to surrounding stimulus, and presented shorter reaction time in automatic postural response.

본 연구는 지속적인 곡예 운동이 여자 체조, 프리스타일 스키어 및 피겨 스케이터 선수의 동적자세 유지 능력에 미치는 영향을 분석하고자 하였다. 이 연구에 참여한 피험자는 운동경력이 4-6년 된 운동선수로서 체조선수 7명, 프리스타일 스키어 선수8명, 피겨 스케이터 7명과 일반 여학생 10명을 통제집단으로 분류하였다. 동적자세의 운동능력을 비교하고자 뉴로컴사의 동적자세측정기를 이용하여 6가지 각 조건에 맞는 이른바, 시각계, 전정계 및 체성감각계가 동원되는 상황을 연출하면서 실험에 임하였다. 자료처리는 일원변량분석을 실시하였고, 사후검증으로는 집단 간의 차이를 보고자 Scheffe로 하였고, 통계학적 유의수준은 .05로 하였다. 연구결과 운동집단 간에는 조건 5에서 프리스타일 선수와 체조선수 간의 유의한 차이가 있었으며, 운동선수 집단과 일반인 여학생 간에는 조건 2, 3, 4, 5, 6에서 유의한 차이가 나타났다. 결론적으로 지속적인 곡예 운동은 평형기관계를 자극하여 동적자세 조절의 향상에 효과가 있는 것으로 사료된다.
