NCT ID NCT06475339
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find the best work/rest schedule for soldiers in hot weather, so they can finish missions faster without overheating or getting too tired. Researchers will measure body temperature, strength, and heart rate in 24 healthy, active adults during exercise in the heat. The results will help military leaders make safer decisions for hot-weather operations.
