Abstract

A running guiding method and a running guiding device are provided, which combine a step frequency and a respiratory rate of a runner to determine whether the step frequency matches the respiratory rate of the runner. When the step frequency does not match the respiratory rate, they provide a prompt of step frequency adjustment based on the step frequency and the respiratory rate of the runner. Thus, an effective running guidance can be provided to the runner and the runner may make an adjustment based on the guidance to improve his/her running efficiency.
