Abstract
An apparatus, method, and medium for generating electrical stimulation, including an electromyogram detector detecting an electromyographic signal of a body, a fatigue index calculator calculating a fatigue index indicating a degree of muscle fatigue by converting the electromyographic signal detected by the electromyogram detector during a predetermined time unit into a frequency-domain electromyographic signal, and an electrical stimulation signal generator adjusting an electrical stimulation signal according to the calculated fatigue index and generating the electrical stimulation signal. Accordingly, a health training/monitoring apparatus can include an electrical stimulation generator adjusting an electrical stimulation signal according to a degree of fatigue and generating the electrical stimulation signal, a physical activity monitor monitoring a physical activity using at least one of a heart rate measurer and an accelerometer, and a mode selector selectively driving the electrical stimulation generator or the physical activity monitor according to an amount of the physical activity.
