And S130, determining an optimized speed and heart rate model according to the acquired treadmill speed data and heart rate measurement data each time.
Specifically, model parameters may be calculated from the treadmill speed data and the heart rate measurement data, and an optimized speed heart rate model may be determined from the calculated model parameters. Wherein, the model parameters are k, tau, xi and omega. The transfer function of the optimized velocity heart rate model is:
Wherein P(s) is a transfer function and s is a complex variable; k, τ, ξ, and ω are all optimized speed heart rate model parameters: k is the model gain, τ is the time constant, ξ is the damping ratio, ω is the characteristic frequency. Wherein k represents the increment of the heart rate after the user reaches the equilibrium state under the unit increment speed; τ represents the speed at which the user reaches equilibrium again at unity acceleration.
