Predicting Responses to Exhausting, Prolonged, And Repeated Exercise Demands (PREPARED) for Heat

Recruiting now · Not applicable

Conditions studied: Hyperthermia, Fatigue; Heat

In brief

The overall goal of this project is to identify a work/rest cycle that allows for faster mission completion needed in emergency situations, compared to current Army heat guidance, while mitigating heat strain and neuromuscular fatigue. This project will determine the trade-off between faster mission completion and risk of heat strain and physical performance decrements. Completion of this project will allow military leaders to make informed decisions by understanding the impact of their choices on the magnitude of physical performance decrements and expected heat casualties, setting up hot weather missions for success.
