1. An exercise support device comprising:

  • an acceleration measuring section which obtains acceleration signals in three axis directions including a vertical direction, a longitudinal direction, and a lateral direction corresponding to a motion of a body of a user performing exercise of cyclically moving feet;

    a vertical acceleration maximum value obtaining section which obtains a first maximum value within a period of one cycle of a foot movement of the user in an acceleration signal in the vertical direction obtained by the acceleration measuring section;

    a signal processing section which searches for a first change point related to foot landing and takeoff motions of the user in a composite acceleration signal obtained by combining acceleration signals in at least two of the three axis directions, in a forward direction of a time point of a second maximum value of the composite acceleration signal, and searches for a second change point related to foot landing and takeoff motions of the user in the composite acceleration signal, in a backward direction of the time point of the second maximum value, within the period of one cycle; and

    a landing period calculating section which obtains a period of time between the first change point and the second change point as a change point interval, when the first change point and the second change point are detected by search in the signal processing section, and calculates a foot landing period of the user while exercising based on the first maximum value of the acceleration signal in the vertical direction and the change point interval.
