We investigated the accuracy of a activity tracker, a wrist-worn device and a waist-worn device that estimate energy expenditure. 100 subjects aged from 20 to 39 yrs engaged in simulation of physical activity, walking and running on a treadmill. For validity, a portable metabolic cart was used as criterion measure. Comparability was tested by wearing of both wrist and waist accelerometers during each 30 min simulation of daily activity, walking and running. The energy expenditure obtained from the wrist-worn accelerometer was highly correlated with those from the portable metabolic cart. Significant and positive correlations were found to be 0.4 and 0.8 (p<0.05), respectively during simulation of daily activity, and walking and running. Significant and positive correlations between waist-worn and the portable metabolic cart were found to be 0.6 and 0.8 (p<0.05), respectively during simulation of daily activity, and walking and running, These data suggest that a multi-sensor accelerometer is a valid device for monitoring energy expenditure during physical exercise and activities of daily living. This device is easier to wear and may facilitate long-term recordings.
