Exercise reduces premature sarcopenia in the absence of PGC‐1α (a) Maximal gip strength (n = 8–10). (b) Four limbs hanging time (n = 8–10). (c) Lean relative to body mass (n = 8–10). (d) muscle mass relative to body weight (n = 5–6). Values are mean ± SEM. *p < .05; **p < .01; indicate statistically significant differences between sedentary and exercised animals of the same genotype, ^# p < .01; ^## p < .01; ^#### p < .001 indicate statistically significant differences between genotypes for sedentary and exercised animals
