## Abstract

Provided is an exercise load control device including: a patient information input unit configured to input patient information which indicates whether a patient using an exercise therapy apparatus is an atrial fibrillation patient; a heart rate information acquisition unit configured to acquire heart rate information which indicates a heart rate of the patient using the exercise therapy apparatus; and a load control unit 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 unit and the heart rate information acquired by the heart rate information acquisition unit.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The exercise load control device according to claim 1, wherein the load control circuitry is configured to control the magnitude of the load so that an average heart rate that is a heart rate calculated with use of as many heart rates indicated by the heart rate information as a moving average of the indicated heart rate matches the set target value by changing, based on the patient information, a moving average for calculating the moving average of the indicated heart rate.

### Claim 3

A method, comprising:
inputting patient information by patient information input circuitry, which indicates whether a patient using an exercise therapy apparatus is an atrial fibrillation patient;
acquiring heart rate information by a heart rate information acquisition circuitry, which indicates a heart rate of the patient using the exercise therapy apparatus; and
controlling by a load control circuitry, a magnitude of a load to be applied by the exercise therapy apparatus to the patient, based on the patient information which has been input and the heart rate information,
wherein the controlling controls 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.

### Claim 4 (depends on 3)

The method according claim 3, wherein:
the controlling controls the magnitude of the load so that an average heart rate that is a heart rate calculated with use of as many heart rates indicated by the heart rate information as a moving average of the indicated heart rate matches the set target value by changing, based on the patient information, a moving average for calculating the moving average of the indicated heart rate.
