Effects of exercise on bone morphology: Vascular channels studied in the rat tibia

Abstract

14 male rats were divided into exercise and control groups to examine the effect of a 1-month exercise program on the vascular morphology of the tibial diaphysis. Following the exercise program the number of haversian canals per mm² increased in the middle third of the cortex, but not in the outer or inner zone. No change was observed in the number of non-haversian canals. The size of the nonhaversian canals increased following the training program, which was not evident in the haversian canals.
