Effect of Hypokinesia on Calcium Loss in Calcium-supplemented and -unsupplemented Rats

Tissue Ca2+ deficiency during HK is more evident with than without Ca2+ supplementation and Ca2+ loss was exacerbated with higher than lower tissue Ca2+ deficiency. This shows that tissue Ca2+ deficiency does not result from the lower Ca2+ content in the food consumed and the total bodily Ca2+ loss is not caused by the higher tissue Ca2+ content but due to the impossibility of the body to use Ca2+ during prolonged HK.
