TABLE 2.

Bivariate correlations between maturity, ethnicity, anthropometric characteristics, percent body fat and pQCT measures of skeletal muscle fat content and MCSA of the calf and thigh and total body lean and fat masses in girls.

	Physical activity	Maturity	Ethnicity	Height	Body mass	Body fat (%)
Calf muscle density (mg/cm³)	0.13^*	−0.01	−0.12	0.02	−0.21^*	−0.37^*
Thigh muscle density (mg/cm³)	0.16^*	−0.03	−0.09	0.01	−0.23^*	−0.48^*
Calf MCSA (mm²)	0.16^*	0.80^*	−0.02	0.72^*	0.88^*	0.40^*
Thigh MCSA (mm²)	0.17^*	0.70^*	0.01	0.65^*	0.78^*	0.38^*
Total body lean mass (kg)	0.15^*	0.89^*	−0.01	0.89^*	0.85^*	0.23^*
Total body fat mass (kg)	0.01	0.56^*	0.06	0.47^*	0.91^*	0.91^*

pQCT = peripheral quantitative computed tomography; MCSA = muscle cross-sectional area (mm²).

Significant, P < 0.05; Pearson’s r for continous and Spearman’s rho for categorical variables.
