Lower physical activity is associated with skeletal muscle fat content in girls.

ABSTRACT:

Unlabelled

Fat contained within skeletal muscle is strongly associated with obesity, type 2 diabetes mellitus, and metabolic syndrome. Physical inactivity may be a risk factor for greater fat infiltration within skeletal muscle during growth.

Purpose

We sought to examine the relationship between physical activity and skeletal muscle fat content of the calf and thigh in girls.

Methods

Data from 464 girls, age 8-13 yr, were used to examine the relationship between physical activity and skeletal muscle fat content of the calf and thigh. Calf and thigh muscle density (mg·cm(-3)), an index of skeletal muscle fat content, was assessed at the 66% tibia and 20% femur sites relative to the respective distal growth plates of the nondominant limb using peripheral quantitative co
