Summary Axon conduction distance, conduction velocity, and conduction time were measured for individual triceps surae motoneurons in Sprague-Dawley rats weighing 230–630 g (i.e., age range 6–16 weeks). Both conduction distance (nerve length) and velocity were closely correlated with weight (r=0.95 and r=0.82, respectively). In contrast, conduction time did not change as weight increased nearly threefold. This striking constancy is probably due to a corresponding increase in axon diameter. It could contribute to maintenance of stable motor performance during rapid growth.
