This method is fast and convenient, however, its accuracy and appropriateness for our use have not been determined. The purpose of this study was to use our workers as subjects to measure the EE of various work elements, and compare the results with the ISO's estimations. EE was measured by using either a portable calorimeter (Cortex MetaMax) or Douglas bag technique. There were17 items, 65 subjects, 144 measurements, and 8-10 subjects in each item. Results showed that there were significant (p<.05) differences between the estimated values and the measured values in 5 items, however, all deviations did not exceed 30﹪, and most of the differences were within 20﹪ of the measured values, indicating that ISO's method provide a practical way to estimate EE of work. There is a few items which due to differences in race, mechanical efficiency, and the adequacy of the prediction equation, requires further studying for more suitable EE estimation equations.
