PROBLEM TO BE SOLVED: To provide a stride measuring system for measuring a precise value of the stride of a subject.SOLUTION: A stride measuring system comprises: a motion sensor 20 attached below the knee joint of a subject; and calculation means 22 for calculating at least the strides of the subject on the basis of data measured by the motion sensor 20. The motion sensor 20 includes an acceleration sensor 24, an angular velocity sensor 26 and a terrestrial magnetism sensor 28.SELECTED DRAWING: Figure 3 |
