Measuring energy expenditure in cardiac patients using the Body Media Armband versus indirect calorimetry. A validation study.

摘要: AIM The purpose of this study was to compare differences in energy expenditure using the newly developed SenseWear Armband body monitor indirect calorimetry cardiac rehabilitation patients. METHODS Twenty-four (62+/-8.1 years) patients completed steady state exercise for 8 minutes on 4 modes (arm ergometry, treadmill walking, recumbent stepping and rowing ergometry). Total cumulative kilojoules were recorded simultaneously by Armband. Statistical analyses assessed degree agreement between 2 measurement methods 3 different versions software. RESULTS correlations version 2.2 armband arm stepper r=0.90, r=0.67, r=0 .80 r=0.74, respectively. There no method during ergometry (p<1.000) (p<0.102). Bland Altman plots revealed greatest spread scores rower treadmill. Between minimal when preliminary r=0.84, r=0.78 r=0.82, CONCLUSIONS accuracy BodyMedia appears be modality dependent those with heart disease software general population. Therefore, information should interpreted cautiously, particularly walking rowing. Initial experiments cardiac-focused are promising, but preliminary.
