We studied the influence of low Po2 under normal atmospheric pressure on the Ca and P metabolism, bone remodeling markers, and biomechanical properties of the femura bone in rats with their hind limbs unloaded. A hypoxic gas mixture (HGM) was given in intermittent regime A and В for 8 hours/day during 28 days. It was shown that regime A slows down the development of osteopenia and may be used in complex with other rehabilitation procedures for preventing the unloading osteopenia.
