Other Effects of High Altitude clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT02731066 Completed - Weight Loss Clinical Trials

Substrate Utilization, Exercise Performance, and Skeletal Muscle Response to Energy Deficit and Altitude Acclimatization

Start date: March 2016
Phase: N/A
Study type: Interventional

This research will evaluate nutrition requirements for missions at high altitude (i.e. >7800 feet above sea level) and the information obtained can be used to optimize nutrient content specifications for combat rations. The objectives are: 1. Determine whether loss of lean body mass resulting from negative calorie balance over a 22-d period at high altitude can be prevented by increasing dietary protein intake. 2. Determine the efficacy of carbohydrate (glucose and fructose) supplementation on aerobic exercise performance at sea level, acute exposure to high altitude, and in response to 22-d period of negative calorie balance at high altitude. 3. Determine cognitive function, sleep patterns, and behavioral responses to high altitude and underfeeding. 4. Determine appetite and eating behavior in response to high altitude and sustained underfeeding. 5. Examine the effects of high altitude, negative calorie balance, dietary intake manipulations on gut health.
