Notes: Animals were weighed prior to sacrifice, body weights (BW) are represented in grams. Gastrocnemius and plantaris muscles were dissected, immediately blotted, and weighed as an estimate of muscle size. The data are presented in grams or as ratio to the animal’s body weight (mg/g). Food consumption was assessed for each experimental group and is reported as grams of food per day. Resveratrol was fed to aged mice for 10 months in a rodent chow that contained 0.05% trans-resveratrol. Resveratrol intake is reported as grams per day normalized to kilogram of body weight (g/kg/day). Significance was set at (p ≤ .05), and all data are represented as mean ± SE.
