Abstract

A swing diagnosis method includes a procedure of calculating levels of a plurality of items including a first item regarding at least one of a backswing and a downswing, and a second item regarding impact on the basis of data regarding a swing, and a procedure of outputting information regarding the levels of the plurality of items.

Claims

1. A swing diagnosis method comprising:

grading, based on data regarding a swing, a plurality of items including (i) a first item regarding at least one of a backswing and a downswing and (ii) a second item regarding impact; and

outputting the grading,

wherein the grading is performed by assigning to each of the first and second items a score calculated from the data regarding the swing,

the score of the first item is calculated using the first item and a first score table stored in a memory, and

the score of the second item is calculated using the second item and a second score table stored in the memory.

2. The swing diagnosis method according to claim 1, wherein the first item includes an item indicating a relationship between (i) a position of a ball hitting portion of an exercise appliance at a first timing during the backswing with respect to at least one virtual plane and (ii) a position of the ball hitting portion at a second timing during the downswing with respect to the at least one virtual plane.

3. The swing diagnosis method according to claim 2, wherein the at least one virtual plane includes:

a first virtual plane that is specified based on (i) a first axis along a target hit ball direction and (ii) a second axis along a longitudinal direction of the exercise appliance before starting the backswing; and

a second virtual plane that forms a first angle with the first virtual plane.

4. The swing diagnosis method according to claim 1, wherein the first item includes an item regarding efficiency of the swing.

5. The swing diagnosis method according to claim 4, wherein the item regarding the swing efficiency is an item indicating a relationship between a deceleration amount and a deceleration period of a holding portion of an exercise appliance in the downswing.

6. The swing diagnosis method according to claim 1, wherein the second item includes an item indicating a relationship between an incidence angle of a ball hitting portion of an exercise appliance and an inclination of the ball hitting portion at impact.

7. The swing diagnosis method according to claim 1, wherein the second item includes an item regarding a speed of an exercise appliance at impact.

8. The swing diagnosis method according to claim 1, wherein the plurality of items include a third item regarding a time at which the backswing transitions to the downswing and a time of the impact.

9. The swing diagnosis method according to claim 8, wherein the third item includes an item indicating a relationship between (i) a rotation angle about a rotation axis of an exercise appliance at the time at which the backswing transitions to the downswing, a longitudinal direction of the exercise appliance being the rotation axis, and (ii) an inclination of a ball hitting portion of the exercise appliance at the time of the impact.

10. A non-transitory computer-readable recording medium recording a swing diagnosis program causing a computer to execute:

grading, based on data regarding a swing, a plurality of items including (i) a first item regarding at least one of a backswing and a downswing and (ii) a second item regarding impact; and

outputting the grading,

wherein the grading is performed by assigning to each of the first and second items a score calculated from the data regarding the swing,

the score of the first item is calculated using the first item and a first score table, and

the score of the second item is calculated using the second item and a second score table.

11. A swing diagnosis apparatus comprising:

a grading calculation section that grades, based on data regarding a swing, a plurality of items including (i) a first item regarding at least one of a backswing and a downswing and (ii) a second item regarding impact;

a memory; and

an output section that outputs the grading,

wherein the grading calculation section performs the grading by assigning to each of the first and second items a score calculated from the data regarding the swing,

the score of the first item is calculated using the first item and a first score table stored in the memory, and

the score of the second item is calculated using the second item and a second score table stored in the memory.

12. A swing diagnosis system comprising:

the swing diagnosis apparatus according to claim 11; and

an inertial sensor that measures the swing.

13. A swing diagnosis apparatus comprising a processor configured to:

grade, based on data regarding a swing, a plurality of items including (i) a first item regarding at least one of a backswing and a downswing and (ii) a second item regarding impact;

a memory; and

output the grading,

wherein the score of the first item is calculated using the first item and a first score table stored in the memory, and

the score of the second item is calculated using the second item and a second score table stored in the memory.

14. The swing diagnosis apparatus according to claim 13, wherein the first item includes an item indicating a relationship between (i) a position of a ball hitting portion of an exercise appliance at a first timing during the backswing with respect to at least one virtual plane and (ii) a position of the ball hitting portion at a second timing during the downswing with respect to the at least one virtual plane.

15. The swing diagnosis apparatus according to claim 14, wherein the at least one virtual plane includes:

a first virtual plane that is specified based on (i) a first axis along a target hit ball direction and (ii) a second axis along a longitudinal direction of the exercise appliance before starting the backswing; and

a second virtual plane that forms a first angle with the first virtual plane.

16. The swing diagnosis apparatus according to claim 13, wherein the first item includes an item regarding efficiency of the swing.

17. The swing diagnosis apparatus according to claim 16, wherein the item regarding the efficiency is an item indicating a relationship between a deceleration amount and a deceleration period of a holding portion of an exercise appliance in the downswing.

18. The swing diagnosis apparatus according to claim 13, wherein the second item includes an item indicating a relationship between an incidence angle of a ball hitting portion of an exercise appliance and an inclination of the ball hitting portion at impact.

19. The swing diagnosis apparatus according to claim 13, wherein the second item includes an item regarding a speed of an exercise appliance at impact.

20. The swing diagnosis apparatus according to claim 13, wherein the plurality of items include a third item regarding a time at which the backswing transitions to the downswing and a time of the impact.

21. The swing diagnosis apparatus according to claim 20, wherein the third item includes an item indicating a relationship between (i) a rotation angle about a rotation axis of an exercise appliance at the time at which the backswing transitions to the downswing, a longitudinal direction of the exercise appliance being the rotation axis, and (ii) an inclination of a ball hitting portion of the exercise appliance at the time of the impact.
