The study investigates the accurate determination of energy expenditure of SenseWear Pro 3 armband (SW3) in normal weight, overweight and obese older people in comparison to spirometry. A total of 50 people between 60 and 82 years of age completed 5 standardized activities (sitting, walking, vacuuming, cycling, stair stepping), which were assessed by spirometry Metamax 3b (MM3b) and SW3. Apparently the SW3 values were significantly lower than those of MM3b in all the 5 activities. The differences became bigger with increasing level of intensity and rising BMI. The intra-class correlation coefficient (ICC) confirmed the poor agreement in 3 out of the 5 activities (sitting, cycling and stair stepping). When using the SW3 in the future it should be considered that both BMI and context recognition of low intense daily routine activities seem to have an impact on measurement accuracy.
