Abstract: Currently the running platform is difficult to ensure the safety and effectiveness of exercise, and cannot realize the personalized fitness. This paper proposes an adaptive control method of running platform for personalized fitness. To meet the runner's physical health and fitness goals, the appropriate exercise intensity values are calculated to match the runner’s personalized fitness. During the running exercise, the runner's heart rate is measured in real time. The slope and speed of the running platform are automatically adjusted by the practiced heart rate to ensure the effective exercise, which shall be in the scope of his exercise intensity. 40 subjects were tested by this exercise intensity adaptive control method. Their average heart rate ratio in exercise was in the range of (0.678, 0.834), and the standard deviation of heart rate was in the range of (3.156, 6.312). The results show that this control method can stably control the exercise heart rate of the subjects within the optimal fitness heart rate interval, and the heart rate fluctuation is small, which not only ensures the effectiveness of the exercise, but also reduces the possibility of running fitness risk. Thus the effectiveness of this control method for the running platform is verified.
