Objective Through the studies on the relations between physiological parameters and human energy metabolism, explore a new way of measuring energy expenditure. Methods Six healthy young men are selected as the test objects. Four physiological parameters (HR, BR, ACC, and BMI) are chosen as the test indicators. There were three states in the test, including stationary state, walking, and jogging. Based on the ELM’s basic principles, an evaluation model of energy metabolism was established. Results The root mean square error (RMSE) and standard deviation (DEV) of energy expenditure evaluation models based on many physiological parameters are smaller than that of the model with a single factor. Conclusions The energy expenditure evaluation models with many physiological parameters have a better and more stable generalization capability, which can be used to accurately measure energy expenditure under different motion states.
