Body Weights, Skeletal Muscle Wet Weights, and CS Activity in Isolated Mitochondria From Young and Mature Animals

	Young	Mature
Body weight (g)	25.57 ± 0.92	36.64 ± 2.34*
Dissected skeletal muscle weight (soleus, gastrocnemius, tibialis anterior, and quadriceps) (g wet weight)	1.92 ± 0.09	1.78 ± 0.11*
Ratio dissected muscle weight-to-body weight	0.075 ± 0.002	0.048 ± 0.008*
Isolated mitochondria CS activity (nmol/min/mg)	379.50 ± 34.9	524.08 ± 40.5*

Notes: Data are mean ± standard deviation of eight separate experiments in young and mature animals. CS = citrate synthase.

^*Significantly different from young animals (p < .05).
