1. A motion analysis apparatus that is configured to execute processes by a processor, the motion analysis apparatus comprising:

  • the processor configured to provide;

    a threshold value determining section that determines whether the amount of inertia detected by an inertial sensor in a first period is within a threshold value range;

    a bias value setting section that sets, if it is determined that the amount of inertia is within the threshold value range, a bias value included in the amount of inertia on the basis of a first average value that is an average value of the amount of inertia detected in the first period; and

    an analysis information calculating section that analyzes a motion of a measurement object using correction data from which the bias value is removed,wherein the threshold value determining section sets the threshold value with reference to a second average value that is an average value of the amount of inertia which is a detection result of the inertial sensor in the entire period, andwhen there is a plurality of the first periods in which the amount of inertia is determined to be within the threshold value range, the bias value setting section sets the bias value on the basis of the first average value in the first period in which a difference between the second average value and the amount of inertia is the smallest.
