1. A walking training system comprising:
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, wherein
the load distribution sensor comprises a plurality of sensors arranged in a matrix on the lower side of the belt,
the plurality of sensors comprises a region set as a sole region, and the sensors that receive a load from a left leg and showing a load value equal to or greater than a first threshold value are set as the sole region,
the sole region is moved in a traveling direction of the belt along with movement of the belt
a region adjacent to the set sole region and receiving a load equal to or greater than the first threshold value is newly set as the sole region, and
the sole region is set so that a size of the sole region is equal to or smaller than a size of the sole of the trainee, the size of a sole of the trainee being stored in advance in a database;
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.
