What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
90 minutes
Energy Expenditure
Time Frame: 90 minutes
The amount of energy the body is expending during work. This is measured using indirect calorimetry.
90 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Perceptual fatigue
Time Frame: 90 minutes
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
