To prevent unreasonable walking exercise, to maintain and improve health and to reduce weight by incorporating the measurement device of a heart rate and a circuit for performing an arithmetic operation and reporting rhythm for maintaining a prescribed heart rate to a walker by an impact.

An equipment incorporating a heart rate measurement part and an arithmetic circuit is mounted on an arm or the like and the electric signals of a pulse signal generation circuit and an amplifier circuit are converted to the impact and vibration in the impact generation part of an electromagnet and an eccentric motor, etc., and reported to a wearing person as signals as a transmission means. Then, in the arithmetic circuit, as the result of comparing the range of a target heart rate with a measured heart rate for the change of the heart rate during walking, correction is performed so as to reduce a pitch in the case of exceeding the upper limit of the target heart rate and to increase the pitch in the case of exceeding a lower limit. An exercise amount calculated in such a manner is arithmetically operated from walking, time and the pitch and calorie consumption or the like is displayed.
