Skeletal response
Abstract
The effect of weightlessness on bone mineral content during prolonged space flight was investigated. The mineral content changes which occurred during Apollo 14, 15, and 16 as measured by photon absorptiometry techniques are presented and compared. Bed rest served as an experimental model to assess the bone mineral changes, and to determine what remedial measures might be used to stem the tide of bone mineral loss. It is concluded that loss of mineral from bone due to the state of weightlessness is comparable to that observed in bed rest subjects.
