The purpose of this study was to investigate the simple calorie consumption calculation method for gait training system in virtual environment. Our gait training system is composed of a computer, software, visual display, and sensing system of gait pattern with a camera and markers and a trainee steps in front of the visual display. The image in the display is proceeded according to his/her stepping speed. In such system, pattern of the gait/step is measured by sensing system. In this research, a simple method of the calorie consumption calculation is investigated from the gait pattern by adding markers to measure upper limbs and trunk. To take the gait patterns such as speed and height of foot and trainee's physical attributes such as their weight and height into account, aggregated kinetic energy and potential energy of body links per a gait period is utilized. Expiratory gas is measured for some gait patterns of seven student participants. Coefficient for each energy is determined to minimize the discrepancy between the calorie consumption calculated by the model and that obtained from expiratory gas analysis. As the result, it was shown that the proposed method can estimate calorie consumption well for various gait patterns and various subjects.
