Primary Outcome Measures

Name	Time	Method
The primary outcome is the level of agreement between energy expenditure as determined by the two study devices (E-sCOVX, Quark RMR) and the reference method (Deltatrac II).[Time of study measurements.]

Secondary Outcome Measures

Name	Time	Method
Respiratory quotient as determined by all three devices (E-sCOVX, Quark RMR, Deltatrac II).[Time of study measurements.]
