In this study, we used the way of reserve heart rate to explore the energy consumption of the fitness crowd when walking and running under the same condition of speed, and to provide the reference to the fitness crowd to choose the exercise intensity and sports mode rationally. Using six male PE majors in Shaanxi Normal University as experimental subjects, the study used the one-dimensional force-measuring treadmill of H/P/COSMOS Gaitway to measure the speed and the POLAR S610i to measure the heart rate. In this study, speed were 4.8km/h and 6.4km/h, test time was 20 minutes. The study finds that when the speed is 4.8km/h, the energy consumption of running is higher than the energy consumption of walking; when the speed is 6.4km/h, the situation is the same as the former. As a result, at the same speed, running will be more conducive to energy consumption, so as to achieve fitness effects.
