1. A muscle fatigue output device, comprising:
a myoelectric sensor that acquires myoelectricity of a user; and
a controller,
the controller:
(a) using the myoelectricity to acquire a value for a frequency characteristic of the myoelectricity;
(b) using the myoelectricity to acquire a value for an amplitude characteristic of the myoelectricity;
(c) acquiring a ratio between the value for the frequency characteristic and the value for the amplitude characteristic as an index for fatigue of a muscle of the user;
(d) outputting information that is based on the index for the fatigue of the muscle of the user; and
(e) determining whether or not the muscle of the user is fatigued, according to whether or not the ratio between the value for the frequency characteristic and the value for the amplitude characteristic is equal to or greater than a first threshold value,
wherein the information indicates whether or not the muscle of the user is fatigued.
