Table 1.

Body weight, total ventricular weight, and serum adiponectin levels

	AL	CR
Body weight at baseline (6 mo old), g	320±5	321±5
Body weight before euthanization (12 mo old), g	449±5	317±7*
Total ventricular weight, g	1.24±0.01	0.92±0.01*
Total ventricular weight/body weight, %	0.28±0.01	0.29±0.01
Serum adiponectin levels, mg/ml	5.0±0.2	9.1±0.9*

Values are means ± SE; n = 14 rats in the ad libitum (AL) group and 14 rats in the caloric restriction (CR) group except for serum adiponectin levels, where n = 8 rats in the AL group and 8 rats in the CR group.

^*P < 0.05 vs. the AL group.
