PROBLEM TO BE SOLVED: To determine a ball hitting position in an exercise machine with a simple configuration.SOLUTION: When an axis along a direction from a grip part to a ball hitting part of an exercise instrument is represented as a first axis, and an axis along a direction orthogonal to the first axis on a ball hitting surface of the ball hitting part is represented as a second axis, a hitting analysis device acquires first inertial output according to the rotation generated around the first axis, and second inertial output according to the rotation generated around the second axis, and determines a hitting position in the exercise instrument on the basis of the first inertial output and the second inertial output at the time of impact during a swing of the exercise instrument.SELECTED DRAWING: Figure 1 |
