Correlation of VO₂max and PPARG mRNA expression with anthropometric characteristics in MZ twins pairs.

Variables	Discordant pairs (n = 9)		Concordant pairs (n = 29)
	VO2max	PPARG	VO2max	PPARG
Body mass (kg)	0.064	0.714**	−0.290*	−0.163
Height (cm)	0.086	0.762*	0.126	0.135
BMI (kg/m2)	−0.109	0.214	−0.472**	−0.172
Waist (cm)	0.046	0.323	−0.426**	−0.201
TR + SB (mm)	−0.540*	−0.357	−0.739**	−0.243
VO2max/PPARG	0.952**		0.309

VO₂max: maximal oxygen uptake (mL·kg⁻¹·min⁻¹); BMI: body mass index; TR + SB: sum of skinfold triceps and subscapular. Spearman's rank correlation tests ^** P = 0.01 level (2-tailed); ^* P = 0.05 level (2-tailed).
