Abstract:
A valuation method of the present invention quantitatively estimates hit feeling of a sport hitting tool. The evaluation method includes: a first step of using a measuring means M1 capable of measuring forces F acting between a swing subject and the sport hitting tool or specific directional components F1 thereof to obtain values of the forces F or the components F1 at times after impact; and a second step of deciding the hit feeling based on the value of the force F or the component F1 at at least one of the times. Preferably, the values of the forces F or the components F1 in a specified period Z12 between a time T1 and a time T2 after the impact are obtained in time series in the first step. Preferably, the hit feeling is evaluated based on an integrated value Sf of the forces F or the components F1 in the specified period Z12 in the second step.
