Analysis of the receiver operating characteristic (ROC) curves showed that the SWA seems to be not sensitive enough to estimate the level of EE at highest intensities.Ĭonclusions: The SWA is not as precise in estimating EE as IC, but it could be a useful tool to determine levels of EE at low intensities. There were indications of heteroscedasticity (R 2 =0.03 P<0.05). Bland-Altman analysis showed a BIAS of 1.56 METs (☑.83 METs) and limits of agreement (LOA) at 95% of −2.03 to 5.16 METs. Results: There were significant differences between the SWA and IC, except in the group that ran at 9 km Participants wore the SWA on their right arm, and their EE was measured by indirect calorimetry (IC) the gold standard. h -1, and sitting/standing at a rate of 30 cycle.Methods: Twenty-three healthy adults (age 40–55 years, mean: 48☓.42 years) performed different types of standardized physical activity (PA) for 10 minutes (rest, walking at 3 and 5 km The objective of this paper was to study the validity of the SWA for quantifying EE levels. *These authors contributed equally to the work.īackground: The SenseWear Armband (SWA) is a monitor that can be used to estimate energy expenditure (EE) however, it has not been validated in healthy adults.
