Effects of age, overload, and resveratrol on CD, C/F, and Log_rSD. a CD was unaffected by age, however increased by overload (P < 0.01). Resveratrol blunted the overload-induced increase in CD, but only in the glycolytic region of the muscle (resveratrol × overload, P < 0.05). b C/F was increased by overload (P < 0.01), but unaffected by age or resveratrol. Both CD and C/F were higher in the oxidative region of the m. plantaris compared to the glycolytic region. c Log_rSD for adult, old and old-res control (black) and overloaded (white) muscle in the oxidative and glycolytic muscle regions. Log_rSD was higher in the glycolytic than in the oxidative region of the m. plantaris muscle (^g P < 0.01), but not affected by age. Overload reduced Log_rSD (*P < 0.01), while resveratrol did not affect the Log_rSD (P > 0.05). Values are mean ± SEM. Black bars control situation; white bars overload situation
