To investigate the thermal energy storage and release patterns in folk dance movements, a theoretical model of "thermal energy storage-release" was constructed and experimentally validated. The model derives key formulas for the input energy and thermal energy storage based on three core assumptions. Three parameters, namely the thermal energy storage density, release rate, and loss coefficient, were defined. The experiments used Mongolian dance (130-140 beats per minute), Dai dance (50-60 beats per minute), and Tibetan dance (90-100 beats per minute) dances as samples. Four professional dancers (aged 22-28, with over eight years of training) participated in this study. Four professional dancers (two male and two female, aged 22-28 years, with over eight years of training) participated in the study. Data were collected using infrared thermal imaging and other equipment, and simulations were performed simultaneously. The results showed that the root mean square error between the experimental and simulation data for the three dances was ?3.1% (minimum 2.1% for Mongolian dance during the movement phase), the deviation in peak trunk temperature was ?0.2?C, and the deviation in thermal energy storage during the movement phase was ?5 J. The model effectively reproduces variations in dance thermal energy, providing theoretical support for energy regulation in ethnic dance movements.
