Outcome Measures
Primary Outcomes (2)
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
Energy Expenditure
The amount of energy the body is expending during work. This is measured using indirect calorimetry.
90 minutes
Secondary Outcomes (1)
Perceptual fatigue
90 minutes
