Table 1. Mitochondrial respiration rates, respiratory control index, and ADP:O ratio in mice.

Group	State 3	State 4	RCI	ADP:O
Exercise	224.1 ± 128.4	61.8 ± 16.5A	4.9 ± 3.7B	1.7 ± 0.8
Control	197.6 ± 41.3	28.8 ± 6.6	7.5 ± 2.0	1.2 ± 0.3

Values are mean ± SE. Unit: nmol/min/mg. AB Significantly different (p<0.05) from the sedentary control mice.
