The purpose

Bone losses are well known to occur in response to unloading (in microgravity or during immobilisation) and in patients with chronic obstructive airway disease (COPD). However, it is unknown whether there is an interactive effect between hypoxia and musculoskeletal unloading upon bone and mineral metabolism. Fourteen non-obese men, who are otherwise healthy, will undergo 3x 21-day interventions; normobaric normoxic bed rest (NBR; FiO2=21%), normobaric hypoxic ambulatory confinement (HAMB; FiO2=14%; ~4000 m simulated altitude), and normobaric hypoxic bed rest (HBR; FiO2=14%). The effects of hypoxia and bedrest on bone metabolism and phosphor-calcic homeostasis will be assessed (before and during each intervention, and 14 days after each intervention period) using venous blood sampling, 24hr urine collections, and peripheral quantitative computerized tomography (pQCT).
