composition (2b→2a). Albeit less pronounced, similar training effects were observed in the middle-aged mice despite running faster and longer than the old. Ten weeks of HR running had a positive effect on muscle mass and morphology in both middle-aged and old mice. The old HR fiber CSA was greater than in old SED and comparable to the middle-aged, and the fibers shifted to a more oxidative composition (2b → 2a). Albeit less pronounced, similar training effects were observed in the middle-aged mice despite running faste
