Abstract
A swing analysis method includes acquiring measurement data measured by an inertial sensor in a swing motion with a golf club, and calculating torque data indicating a temporal change of a torque exerted on the golf club by analyzing the measurement data using a head speed coordination system having a first axis including a speed vector of a head of the golf club, a second axis being orthogonal to the first axis and extending along a shaft of the golf club, and a third axis orthogonal to both the first axis and the second axis.
