Twenty-four hour urine pools were collected and aliquoted for determination of calcium/bone status for each subject. The subject’s urine was collected for each 24 hour period. Three 10ml aliquots were taken from each 24 hour collection and frozen at -80C. The urine calcium was then analyzed using Flame Atomic Absorption Spectrophotometry.
Projected results are a possible increase in calcium levels over a 6 day period for each bed rest subject. This experiment has concluded in ground-based studies sponsored by the National Aeronautics and Space Administration's Human Adaptation and Countermeasures Division. This experiment was conducted during the Lunar Analog Feasibility Study. LSDA does not expect to receive results from this study.
