Army tests common pill to boost soldier stamina in thin air

This study aimed to understand if a medication called pioglitazone, which makes the body more sensitive to insulin, could help people use sugar from drinks more efficiently when exercising at very high altitudes. It involved 9 healthy, active men who performed treadmill workouts in a special low-oxygen chamber, taking either the drug or a placebo. The main goal was to gather detailed knowledge about how the body processes fuel in extreme conditions, not to provide a direct treatment benefit to participants.
