A method for measuring a physical condition of an individual by using a post-exercise heart rate recovery rate, has steps of: acquiring heart rates of the individual during a recovery period after an 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.一種利用心率回復率量測體能狀態的方法,包括以下步驟:在一個體運動後量測該個體在一回復期的心率;根據該個體的心率記錄,以非線性回歸方程式計算該個體的心率回復率,該非線性回歸方程式中包括一代表該個體的心率回復率的參數及根據該參數決定該個體體能狀態,藉此,量測心率回復率的準確度比其他習知方法較佳。
