It is well accepted that calcium supplementation in combination with resistance exercise contribute to net bone formation. However, this fact has been supported with limited research. This study seeks to reinforce this accepted knowledge. In addition, copper and/or silicon supplementation in addition to calcium supplementation may enhance the effects of calcium supplementation alone. This effect may be through improved absorption or function and has yet to be proven. Silicon, in fact, is not presently considered to be an essential nutrient, although it may become one. This study also seeks to find evidence that one or both of these supplements may improve the effect of calcium on net bone formation. Such data would be helpful in the treatment and prevention of osteoporosis.
