PCT No. PCT/JP97/00928 Sec. 371 Date Jan. 23, 1998 Sec. 102(e) Date Jan. 23, 1998 PCT Filed Mar. 21, 1997 PCT Pub. No. WO97/35514 PCT Pub. Date Oct. 2, 1997An exercise intensity and exercise quantity measuring device is disclosed, which is capable of measuring the exercise intensity, irrespective of the type, of exercise, and measuring the exercise quantity only when the user is carrying out exercise of suitable intensity. The user first estimates his Vo2max in advance by the conventional direct method, and inputs this value into the device. The device determines upper and lower limit values of pulse rate corresponding to this Vo2max. During the time of exercise when pulse rate is between the upper and lower limit values, CPU 308 increments the accumulated time stored in RAM 309, at intervals based on a clock pulse supplied by oscillation circuit 311 and frequency dividing circuit 312. At the same time, CPU 308 compares the pulse waveform during exercise and the pulse waveform at rest, and estimates the exercise intensity.
