Body weight (a), food intake (b), lean body mass in % (c), fat % (d), perigonadal visceral adipose tissue (V-AT) weight (e) and inguinal subcutaneous adipose tissue (S-AT) weight from 3 month old (mo) untrained chow mice (UT-C), 15 month old untrained chow mice (UT-C), 15 month old untrained resveratrol (RSV) supplemented mice (UT-R), 15 month old exercise trained (T-C) and 15 month old exercise trained and RSV supplemented (T-R) whole body PGC-1α knockout (KO) and littermate wild type (WT) mice. Values are presented as means ± S.E.; n=8–10 except in (c) and (d) where n=3–8. †: Significantly different from 3 month old UT-C within genotype, p<0.05. *: Significantly different from 15 month old UT-C within genotype, p<0.05. (*): Tends to be significantly different from 15 month old UT-C within genotype, 0.05≤p<0.1. #: Significantly different from WT within group, p<0.05. (#) Tends to be significantly different from WT within group, 0.05≤p<0.1.
