Abstract: A method for measuring a physical condition of an individual by using a post-exercise heart rate recovery rate is provided and, has steps of: acquiring a heart rate of the individual during a recovery period after a physical activity of the individual; calculating a heart rates recovery rate of the individual using a nonlinear regression equation, which includes a parameter representing the rate of heart rate recovery; and determining the physical condition of the individual based upon the parameter. Hereby, the accuracy of measuring the heart rate recovery rate is better than other conventional methods.
