Fig. 1From: Voluntary resistance wheel exercise from mid-life prevents sarcopenia and increases markers of mitochondrial function and autophagy in muscles of old male and female C57BL/6J miceAverage weekly body weights (a), food consumption (b), running distance (c), speed (d), and external work (e) in males and females in both SED and RWE cohorts over 34 weeks. The asterisks indicate significant differences between sedentary and exercised mice (data were pooled for sex; *P < 0.05; **P < 0.01). Diamond indicates a significant effect of age ♦ P < 0.05. Data for “speed” at week 2 are missing due to technical issues. For each weekly time point, data are mean ± SEM. N = 6–10 mice per groupBack to article page
