Abstract
A muscular strength estimation device according to the present invention comprises load supply means for applying a prescribed exercise load to a subject; oxygen saturation measuring means for measuring, while the exercise load is being applied to the subject, the oxygen saturation in the blood circulating through the muscle to which the exercise load is applied; minimum value detection means for detecting the oxygen saturation minimum value during measurement; recording means for recording in advance a correlation table showing the correlation between the subject's oxygen saturation and muscular strength; and calculation means for calculating the muscular strength corresponding to the oxygen saturation minimum value, from the correlation table.
