Interventions

  • 30/30 work/rest cycle — OTHER
    Participants will walk on a treadmill while wearing a weighted backpack to a work/rest cycle of 30 minutes of work followed by 30 minutes of rest.
  • 30/20 work/rest cycle — OTHER
    Participants will walk on a treadmill while wearing a weighted backpack to a work/rest cycle of 30 minutes of work followed by 20 minutes of rest.
  • 40/30 work/rest cycle — OTHER
    Participants will walk on a treadmill while wearing a weighted backpack to a work/rest cycle of 40 minutes of work followed by 30 minutes of rest.
  • 20/12 work/rest cycle — OTHER
    Participants will walk on a treadmill while wearing a weighted backpack to a work/rest cycle of 20 minutes of work followed by 12 minutes of rest.

Study Details

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.

Arms

  • Active Comparator: 30/30 work/rest cycle first
    Participants will first complete the 30/30 work/rest cycle, and then complete the other three conditions in a randomized fashion
  • Experimental: 30/20 work/rest cycle first
    Participants will first complete the 30/20 work/rest cycle, and then complete the other three conditions in a randomized fashion
  • Experimental: 40/30 work/rest cycle first
    Participants will first complete the 40/30 work/rest cycle, and then complete the other three conditions in a randomized fashion
  • Experimental: 20/12 work/rest cycle first
    Participants will first complete the 20/12 work/rest cycle, and then complete the other three conditions in a randomized fashion
