Clinical Trial Summary

The purpose of this study is to determine the impact of varying hot environments on physiological and perceptual fatigue during work.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Smoothness of movement	The variable, jerk, determines smoothness or unevenness of physical movement during work. This is measured using accelerometers placed along the spine, ankle, and shoulder.	90 minutes
Primary	Energy Expenditure	The amount of energy the body is expending during work. This is measured using indirect calorimetry.	90 minutes
Secondary	Perceptual fatigue	The degree of fatigue that the subjects perceive during work. This is measured using a subjective likert 0-10 scale named the Fatigue Scale with 0 indicting "no fatigue at all" and 10 indicating "completely fatigued".	90 minutes
