1. A system for detecting an anaerobic threshold heart rate of a user, comprising:

  • a heart rate sensor configured to obtain first physiological data and second physiological data while the user is exercising; and

    a microprocessor configured to receive the first physiological data and the second physiological data from the heart rate sensor and configured to implement a first calculating module and a second calculating module;

    the first calculating module configured to calculate third physiological data according to the second physiological data; and

    the second calculating module configured to obtain an interval of the third physiological data corresponding to an estimated range of the first physiological data, and obtain a turning point of a curve fitting the third physiological data within the interval to determine the anaerobic threshold heart rate of the user,wherein the first physiological data is heart rate data, the second physiological data is R-R interval data or peak-to-peak interval data, and the third physiological data is standard deviation of normal-to-normal data.
