Research Abstract

We comprehensively clarified the sequential changes of bone contour, turnover, and strength after skeletal loading and unloading at the tissue, cellular and molecular levels. The resistant exercise (jumping) increased bone volume and bone strength more effectively by promoting cortical drift and by increasing bone formation, compared to the aerobic exercise (running), in the growing rats.
We originally created the voluntarily climbing-up animal model. The trabecular bone volume of the proximal tibia was increased at 2 and 4 weeks after the exercise. Osteoclast surface was decreased at 2 weeks and bone formation was increased at 4 weeks after the exercise. In the cell culture study, the bone marrow cells obtained from the tibias of 2-week exercise mice showed the increase of alkaline phosphatase-positive CFU-f and the decrease of TRAP-positive multinucleated cells. We also revealed that nitric oxide is essential for trabecular bone formation at the reloading after unloading.
