骨骼肌的结构可以通过定量（大小）和定性（组成）属性来表征，而这些属性被大量报道为受身体肥胖的影响。这项研究测试的假设，身体肥胖对这些肌肉特性产生系统的影响，并评估可能的功能影响的动作。用计算机断层扫描测定了21名男性（BMI=21- 36 kgm（-2）;年龄=31- 71岁）的下肢SM体积（VSM）和衰减（ATTSM），这是肌肉中脂质浸润的反向测量。女性18例（BMI=19- 35 kgm（-2）;年龄=32- 76岁）。校正年龄后，多变量回归分析显示，肥胖与肥胖之间呈正相关（P
The structure of skeletal muscle (SM) can be characterized by quantitative (size) and qualitative (composition) attributes, which are disparately reported to be influenced by body adiposity. This study tests the hypothesis that body adiposity exerts a systematic influence on these muscle characteristics and evaluates the possible functional implications for movements. Lower limb SM volume (VSM) and attenuation (ATTSM), an inverse measure of lipid infiltration in muscle, were determined with computed tomography in 21 men (BMI=21-36kgm(-2); age=31-71years.) and 18 women (BMI=19-35kgm(-2); age=32-76years.). After adjusting for age, a multivariate regression analysis revealed that body adiposity positively correlated (P
