Abstract

The purpose of this study was to explore differences of spinal stabilization muscle strength between groups classified by BMI for industrial workers. Fifty subjects participated in this study were divided to obesity group(BMI over $25kg/m^2$) and non obesity group(BMI under $25kg/m^2$). Independent t-test was applied for analysis. The results showed the following. There were significant differences in $0^{\circ}$ Forward on sagittal plane, in both $90^{\circ}$ Left, $90^{\circ}$ Right on coronal plane, in $45^{\circ}$ Left Tilt, $45^{\circ}$ Right Tilt on diagonal plane between groups. Last, There were significant differences in an amount of soft lean muscle and an amount of skeletal muscle between groups. These results shows that spinal stabilization muscle strength program for the obese should be considered in sagittal plane, coronal plane, and diagonal plane.

본 연구는 대기업에 근무하는 산업체 근로자를 대상으로 비만도에 따른 척추안정화근력의 차이를 분석하는데 목적을 두었다. 편의표본 추출방법(Convenience Sampling Method)에 의하여 50명을 표본을 추출하여, 체질량지수(BMI) $25kg/m^2$ 이상을 비만군(25명), 이하를 정상군(25명)으로 분류하여 독립표본 t검정(Independent t-test)으로 분석하였다. 집단간 척추안정화근력의 측정결과 정상군의 평균이 비만군에 비해 모두 높았으며, Sagittal Plane에서는 $0^{\circ}$ Forward에서 유의한 차이를 보였고, Coronal plane에서는 $90^{\circ}$ Left, $90^{\circ}$ Right에서 유의한 차이를 보였으며, Diagonal Plane에서는 $45^{\circ}$ Left Tilt, $45^{\circ}$ Right Tilt에 유의한 차이를 보였다. BMI 분류에 따른 근육량과 골격근량의 분석결과에서는 비만군이 정상군에 비해 모두 높았으며 통계적으로 유의한 차이를 보였다. 비만군이 정상군에 비해 근육량은 많지만 척추안정화근력은 약하다는 것을 감안하여 Sagittal Plane, Coronal plane, Diagonal Plane에서의 비만인을 위한 척추안정화 강화 프로그램의 개발이 요구된다.
