PROBLEM TO BE SOLVED: To provide an exercise analysis method that can objectively determine a swing of exercise equipment at impact.SOLUTION: The exercise analysis method calculates a level of a swing based on a relationship of a first angle δ formed by a tangential direction of a locus of a swing of a striking part 3b of the exercise equipment 3 at impact and a striking target direction and a second angle φ formed by a direction orthogonal to a striking face of the striking part at impact and the striking target direction using output of an inertial sensor 10 for measuring a swing of the exercise equipment 3.SELECTED DRAWING: Figure 21
