초록
본 연구의 목적은 지속적인 생활무용 참여가 비만 여성들의 동맥혈류변화에 미치는 영향을 규명하는 것이다. 이 연구를 수행하기 위하여 실험군 13명, 통제군 10명 등 두 집단으로 분류하였다. 실험군은 본 연구의 12주간의 생활무용 프로그램에 참여 하였다. 실험군은 초음파 동맥혈류 측정기(ultra-sound transcranial doppler; TCD)를 이용한 혈류 속도, 맥박, 저항 및 협착비율을 각 시기별 1회 측정하였으며, 측정 시기별 각종변인의 변화와 변인간의 상호관계를 분석한 결과 실험군은 12주 전반에 걸쳐 평균혈류속도(MBV) 18.6%, 맥박지수(PI) 11.4%, 혈류저항지수(BRI) 8.70%, 동맥협착지수(ASI) 18.6%의 유의하게 높은 감소율로 나타났으며, 통제군은 각 기간별 약간의 증감 현상만 있었을 뿐 유의한 변화는 없었다. 각 집단과 처치기간간의 상호작용 효과는 MBV, PI에서 유의한 차가 나타났다. 이상의 결과를 살펴볼 때 지속적인 생활무용 참여는 심장을 중심으로 발현되는 동맥 혈류 속도, 맥박과 저항 및 동맥 협착 비율의 유의한 변화 양상을 통해 심혈관계 개선에 긍정적인 영향을 미친 것으로 사료된다.
Abstract
The purpose of this study was to analyze the effect of continued participation in practical dance on artery blood flow variable in aged obese women. Twenty three women were studied : experimental group(13), cotrol group(10). Age range is 30～40. The subjects tested ultra-sound transcranial doppler(TCD) during continued participation in practical dance. Mean blood flow velocity(MBV)․pulsatility index(PI) and blood resistance index(BRI)․artery stricture index(ASI) were measured at ontinued participation duration. The conclusion of the study was as follows : Change of artery blood flow during practical dance in each group, experimental group were significant reduced of MBV 18.6%, PI 11.4%, BRI 8.70%, ASI 18.6% during participation duration, But control group were not significant different during each duration. Reactive effects for repeated ANOVA were significant different between each group and prescriptive duration in MBV, PI. In summary, when practical dance is to do continued participation. Cadiovascular system in obesity women considered likely promote to functional improvement with variation on bloow flow velocity, pulsatility and resistance․artery stricture ratio.
