GROSS, T. S., S. L. POLIACHIK, B. J. AUSK, D. A. SANFORD, B. A. BECKER, and S. SRINIVASAN. Why rest stimulates bone formation: A hypothesis based on complex adaptive phenomenon. Exerc. Sport Sci. Rev., Vol. 32, No. 1, pp. 9–13, 2004. Moderate exercise is an ineffective strategy to build bone mass. The authors present data demonstrating that allowing bone to rest between each load cycle transforms low- and moderate-magnitude mechanical loading into a signal that potently induces bone accretion. They hypothesize that the osteogenic nature of rest-inserted loading arises by enabling osteocytes to communicate as a small world network.
