초록
본 연구는 발레 무용수들을 대상으로 TC/HDL-C ratio, leucine, isoleucine, valine(BCAA)을 관찰변인으로 선정하여 TC/HDL-C ratio와 Branched-Chin Amino Acids(BCAA) 간의 상관관계를 규명함으로써 발레무용수들의 효율적인 무용수행능력과 체력 향상에 필요한 기초자료를 제시하는데 연구의 목적이 있다. 본 연구의 대상자는 연구의 목적을 충분히 이해하고 실험참가에 동의한 S대학교 발레전공 여대생 14명을 무선표집(random sampling)하였고 평상시와 같이 식생활을 유지하도록 하였다. 모든 연구 대상자들의 신체적 측정요인으로는 신장, 체중, 체지방률, 신체질량지수(BMI)를 측정하였다(In-Body 520, Biospace Co., Korea). TC 및 HDL-C 분석에는 Enzymatic Colorimetric, BCAA 분석에는 HPLC(Biochrom 20, U.S.A)으로 분석되었다. 구체적인 통계기법으로는 상관분석(analysis of correlation), 단순선형회귀분석(analysis of simple linear regression)을 사용하여, Durbin Watson검증을 통하여 잔차분석을 하였으며, 이때 유의 수준은 .05로 설정하였다. 연구결과는 발레무용수의 TC/HDL-C ratio을 종속변인으로 Branched Chain Acids(BCAA)인 Isoleucine, Leucine, Valine(BCAA)를 독립변인으로 한 단순회귀분석에서 각각 0.71, 0.50, 0.46의 설명력을 나타낸 회귀식이 성립됨으로써 발레 전공 여대생의 TC/HDL-C ratio에 BCAA가 유의하게 영향을 미치는 독립변수로 나타났다. 본 연구에서는 발레 무용수들의 Branched Chain Acids(BCAA)의 농도가 증가할수록 TC/HDL-C ratio가 낮게 나타날 것으로 예측할 수 있으며, 이러한 인과관계는 여성 발레무용수들의 발레 동작 및 연습 시 에너지 대사과정에서 BCAA의 효율적인 활용과 더불어 발레무용수들의 공연향상 뿐만 아니라 건강기능의 향상에 관한 효율적인 자료로 활용될 수 있다고 기대한다.
Abstract
The purpose of this study was to determine the relationship between Branched Chain Amino Acid(BCAA) and TC/HDL-C ratio in female ballet dancers. Fourteen college female ballet dancers(age:18.3±.0.5yrs, BMI:19.2±1.2m²) were participated in this study, and study subjects measured percent body fat, fat mass, weight, body mass index and isoleucine, leucine, valine. were also measured percent body fat, fat mass, weight, body mass index were analyzed using bioelectrical impedance(Biospace Co.). Use blood-gathering analyzed about isoleucine, leucine, valine of Amino Acid(Biochrom 20, U.S.A) and TC/HDL-C ratio(Enzymatic Colorimetric). Analysis of multiple Correlation, Analysis of Simple liner Regression, and Dubin Watson Test were applied for the statistical analysis using SPSS 12.0. This results showed that TC/HDL-C ratio was significantly associated with isoleucine(p<.05), leucine(p<.05), and valine(p<.05) in female ballet dancers. it was found that TC/HDL-C ratio is in proportion to BCAA in female ballet dancer. In conclusion, it does appear that several significant research topics in amino acid biochemistry metabolism as well as ballet dancer and nutrition can be explored profitably in the future using experimental designs involving interaction between amino acid status and exercise performance.
