- 概要
- The purpose of this study was to assess the relationship between echo intensity of the thigh muscles, which is an index of adipose tissue infiltration in muscle, and functional ability or body composition in elderly individuals. Thirty-six healthy elderly men and women (72.2 ± 4.4 year-old) engaged in this study. Muscle mass, fat mass, body weight, and percent body fat was measured using bioelectrical impedance device. Subcutaneous fat thickness and muscle thickness at the anterior and lateral thigh was measured using B-mode ultrasonography. Echo intensity of rectus femoris and vastus lateralis was also calculated from ultrasonographic images based on grey scale level. Supine up time was measured as functional ability of the subjects. Echo intensity of rectus femoris and vastus lateralis was significantly correlated with anterior and lateral muscle thicknesses (r = -0.471 to -0.594, P < 0.01 to 0.001). Stepwise linear regression analysis was performed as a dependent variable of echo intensity of rectus femoris or that of vastus lateralis and as independent variables of parameters in body composition, muscle thickness, and supine up. Anterior muscle thickness and supine up was extracted to predict echo intensity of rectus femoris, and lateral muscle thickness was extracted to predict echo intensity of vastus lateralis. These results suggest that combination of muscle thickness and supine up or muscle thickness alone might predict metabolic abnormality such as insulin resistance based on assessment of echo intensity.
