To compare the effects of IV iron versus placebo (saline) injection on arterial oxygen saturation, submaximal exercise responses, and 2-mile treadmill time-trial performance during acute exposure to hypobaric hypoxia (430 mmHg, simulating \~4800m) assessed 1 and 14 days after treatment. Primary Hypothesis 1: IV iron treatment will improve arterial oxygen saturation at rest and during exercise in acute hypobaric hypoxia and this effect will persist for 2 weeks Primary Hypothesis 2) IV iron treatment will improve 2-mile treadmill time trial performance in acute hypobaric hypoxia and this effect will persist for 2 weeks
This study will use a double-blind randomized study design in which one group will receive iron (n = 12; Injectafer, 15 mg/kg up to 1000 mg) and the other a placebo (n = 12; saline). Twenty-four participants will complete seven study visits: Visit 1: Orientation visit consisting of dual-energy X-ray absorptiometry scan (DEXA), pulmonary function test, assessment of peak aerobic capacity (VO2peak); Visits 2-3: familiarization consisting of exercise battery (20 minutes of walking followed by 2 mile treadmill time trial); Visits 4, 6-7: high altitude trial (4,800 m) in which skin blood flow durin…
