Exercise load control device

An exercise load control device, comprising:

• patient information input circuitry configured to input patient information which indicates whether a patient using an exercise therapy apparatus is an atrial fibrillation patient;
• heart rate information acquisition circuitry configured to acquire heart rate information which indicates a heart rate of the patient using the exercise therapy apparatus;
• and
• load control circuitry configured to control a magnitude of a load to be applied by the exercise therapy apparatus to the patient, based on the patient information input by the patient information input circuitry and the heart rate information acquired by the heart rate information acquisition circuitry,
• wherein the load control circuitry is configured to control the magnitude of the load so that the heart rate indicated by the heart rate information matches a set target value by changing. based on the patient information, at least one coefficient out of a first coefficient by which a difference between the heart rate and the set target value is to be multiplied and a second coefficient by which the difference, or an integral value using the difference, is to be multiplied.
