Wall-to-lumen ratio (W/L) of resistance arteries from young and old male sedentary (YMS and OMS, respectively) and exercise-trained (YME and OME, respectively) rats. Exercise training decreased W/L. Aging increases W/L; exercise training ameliorates effects of aging to ratio to a level comparable to YMS. Values are means ± SE; n, no. of rats. *P < 0.05 vs. corresponding old group. ^P < 0.05 vs. age-matched sedentary group.
