Muscle activity output system

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.
