A walking training system according to the present embodiment includes: a treadmill; a load distribution sensor that is provided on a lower side of a belt of the treadmill so as not to move together with the belt and that detects a distribution of a load received from a sole of a trainee riding on the belt of the treadmill; an extraction unit that extracts a load distribution in a region corresponding to a position of the sole of the trainee during walking training, out of a load distribution detected by the load distribution sensor; and a determination unit that determines a walking state of the trainee based on the load distribution extracted by the extraction unit. A walking training system according to the present application provides improved training to a trainee by improving the accuracy of determining the walking state of the trainee.

A balance training system including a mobile plate configured to support a sole of a trainee in a standing state, a first member fixed on the mobile plate, a load distribution sensor including a plurality of sensors arranged in a matrix under the mobile plate and configured to detect a load received from the trainee riding on the mobile plate and a position of the first member, and a control unit configured to calculate a net moving amount of a center of gravity position of the trainee based on a difference between a moving amount of a center of gravity position of the load received from the trainee detected by the load distribution sensor and a moving amount of the position of the first member detected by the load distribution sensor and to control a movement of the mobile plate based on a result of the calculation.

A training system includes a riding plate, a load sensor, a first center of gravity calculation unit, an image-capturing unit, a second center of gravity estimation unit, and a determination unit. The load sensor detects a load that the riding plate receives from a trainee. The first center of gravity calculation unit calculates a first center of gravity, which is a center of gravity of a load, based on the load detected by the load sensor. The image-capturing unit acquires image data of an image including a posture of the trainee. The second center of gravity estimation unit estimates a second center of gravity, which is a centroid position of the trainee, based on the image data. The determination unit determines that an alert to the trainee should be output based on a difference between the first center of gravity and the second center of gravity.
