Study Overview
Brief Summary
The purpose of this study is to determine the impact of varying hot environments on physiological and perceptual fatigue during work.
Detailed Description
After providing written informed consent and screening, subjects will complete two experimental visits during which they will complete treadmill work in either a hot/dry or warm/humid environment.

Warm/Humid
Intervention: Warm/Humid (Other)
Outcomes
Primary Outcomes
Smoothness of movement
Time Frame: 90 minutes
The variable, jerk, determines smoothness or unevenness of physical movement during work. This is measured using accelerometers placed along the spine, ankle, and shoulder.
Energy Expenditure
Time Frame: 90 minutes
The amount of energy the body is expending during work. This is measured using indirect calorimetry.
Secondary Outcomes
- Perceptual fatigue(90 minutes)
