Methods: Ten male adults underwent 20 min treadmill exercise at 40%VO2max, 60% VO2max, 80% VO2max respectively in high temperature and humidity environment (temperature (33±1)℃, relative humidity (65±3)%). Energy expenditure was measured by fixed gas metabolism apparatus (Cortex MetaLyzer 3B) and SWA (SenseWear Pro3 Armband). Data was analyzed by the methods of paired t test, regression analysis, correlation analysis, ICC coefficient and Bland-Altman. Results: SWA underestimated the energy expenditure of quiet state (7.6%), 60% VO2max intensity exercise (15.4%) and 80% VO2max intensity exercise (28.8%), but it overestimated the energy expenditure of 40% VO2max intensity exercise (15.6%). The relevance and consistency of SWA and IC in predicting energy consumption were good (r = 0.73-0.85, IC = 0.77-0.90). Conclusion: In high temperature and humidity environment, there are high relevance and high consistency between the predicting energy expenditure of SWA and IC. SWA is more suitable for estimating energy expenditure in low intensity exercise
