A control unit of a measuring apparatus controls a sound driving circuit to make a sounding unit generate pitch sounds at a predetermined pace for three minutes. After generation of the pitch sounds for three minutes, a heart rate sensor measures a heart rate of an exerciser who has executed an exercise in synchronism with the generated pitch sounds, and the measured heart rate is stored in RAM. Further, the control unit controls the sounding unit to generate pitch sounds at a different pace for another three minutes, and a heart rate of the exerciser is measured and stored similarly. Based on the measured heart rates and personal data such as an age of the exerciser input through a key input unit, a level of objective physical strength of the exerciser is calculated and displayed on a display device. In other words, physical strength of the exerciser is objectively evaluated based on physical data such as a heart rate that varies when the exerciser performs the exercise.
