Abstract

A muscle activity output system includes: a muscle activity database configured to hold movable part attitude information and muscle activity information in such a manner that the movable part attitude information and the muscle activity information are linked to each other; and a processor. The movable part attitude information indicates an attitude of a movable part of training equipment. The muscle activity information indicates a muscle activity of each of muscle sites of the exerciser. The processor is configured to acquire the movable part attitude information while the exerciser is moving the body along the trajectory, acquire current muscle activity information for each of the muscle sites based on current movable part attitude information of the training equipment and the muscle activity database, and output the current muscle activity information for each of the muscle sites.

Claims (22)

1. A muscle activity output system, comprising:

a memory storing a muscle activity database that holds correspondence information between movable part attitude information and muscle activity information linked to the movable part attitude information, the movable part attitude information indicating an attitude of a movable part of training equipment when an exerciser moves a body of the exerciser along a trajectory defined by the training equipment, the muscle activity information indicating a muscle activity of each of muscle parts of the exerciser, the training equipment being equipment that applies a load to muscles of the exerciser;

a display device configured to display a human body muscle anatomy model of which a corresponding part to each muscle part is colored according to a muscle activity indicated in a current muscle activity information; and

a processor configured to

acquire the movable part attitude information while the exerciser is moving the body along the trajectory,

acquire the current muscle activity information for each of the muscle parts corresponding to the acquired movable part attitude information, from the correspondence information in the muscle activity database, and

output the current muscle activity information for each of the muscle parts.

2. The muscle activity output system according to claim 1 , wherein:

the training equipment is a pedal exercise device with which the exerciser performs a pedaling exercise while being in a sitting position; and

the movable part attitude information of the training equipment is crank angle information indicating a crank angle of the pedal exercise device.

3. The muscle activity output system according to claim 2 , wherein the correspondence information in the muscle activity database is generated by a simulator calculating a change in muscle activity of each muscle part that occurs with a change in the crank angle using a human body model and an exercise device model.

4. The muscle activity output system according to claim 1 , wherein:

the muscle activity database holds the correspondence information in such a manner that the correspondence information is linked to exercise condition information indicating an exercise condition of the exerciser; and

the processor is configured to

acquire the exercise condition information, and

acquire the current muscle activity information for each of the muscle parts from the correspondence information corresponding to the acquired exercise condition information.

5. The muscle activity output system according to claim 1 , wherein:

the muscle activity database holds the correspondence information in such a manner that the correspondence information is linked to body-specific information of the exerciser; and

the processor is configured to

acquire the body-specific information, and

acquire the current muscle activity information for each of the muscle parts from the correspondence information corresponding to the acquired body-specific information.

6. The muscle activity output system according to claim 1 , wherein the muscle activity information indicates muscle activity of deep muscles of the exerciser.
