Association of intramuscular adipose tissue accumulation with mitochondrial function

Variables	β (95% Confidence Interval)		Adjusted P Value
	Unadjusted, n=51	Adjusted, n=51
Intramuscular adipose tissue %	2.29 (0.86 to 3.72)	2.88 (1.35 to 4.40)	<0.001
Age, yr		0.12 (−0.28 to 0.51)	0.56
BMI, kg/m2		−0.95 (−1.67 to −0.24)	0.01
Sex, women		0.42 (−8.19 to 9.03)	0.92
Race, white		−5.89 (−14.57 to 2.79)	0.17

Mitochondrial function (dependent variable) was measured using the τ time constant (in seconds). Each percentage increase in intramuscular adipose tissue was positively associated with 2.3 s more in the τ time constant. BMI, body mass index.
