Muscle mass, fiber area, total fiber number, fiber population and capillarity were assessed in 6- and 25-month-old animals trained by treadmill running at 75% mean maximal capacity for 10 weeks. Serial cross-sections were stained for ATPase activity to differentiate fiber types and expose capillaries. Aging and training effects were demonstrated in maximal running speed and endurance running time. Soleus muscle mass increased in the aged, however, soleus and EDL total fiber number were declining. When adjusted for muscle weight, a significant reduction existed in fiber number for the aged soleus. Fiber area increased in the old soleus compared to young. All changes in the EDL were specific to the deep region. While there was a tendency for the capillaries/fiber and fiber area to be higher with training in the Type I fibers of the soleus, it was only significant for the young animals. Thus, while the majority of variables that showed a training effect did so across both age groups, this was not the case for vascularity. Age-associated changes in muscle morphology appear to be both muscle and fiber specific.
