Abstract

A swing diagnosis apparatus includes a level calculation section that calculates a level on the basis of a relationship between a rotation angle about a rotation axis of an exercise appliance at a predetermined timing between the time of starting a backswing and the time of impact with a longitudinal direction of the exercise appliance as the rotation axis, and an inclination of a ball hitting portion of the exercise appliance at impact.

Claims

1. A swing diagnosis apparatus comprising:

a level calculation section that calculates a level on the basis of a relationship between a rotation angle about a rotation axis of an exercise appliance at a predetermined timing between the time of starting a backswing and the time of impact with a longitudinal direction of the exercise appliance as the rotation axis, and an inclination of a ball hitting portion of the exercise appliance at impact.

2. The swing diagnosis apparatus according to claim 1,

wherein the rotation angle is an angle by which the exercise appliance is rotated about the rotation axis from the time of starting the backswing to the predetermined timing.

3. The swing diagnosis apparatus according to claim 1,

wherein the predetermined timing is the time at which the backswing transitions to a downswing.

4. The swing diagnosis apparatus according to claim 1,

wherein the inclination of the ball hitting portion is an angle formed between an outer edge of a hitting surface of the ball hitting portion and a virtual straight line orthogonal to a target hit ball direction in a plan view.

5. The swing diagnosis apparatus according to claim 1,

wherein the level calculation section calculates the level according to a curved state of a hit ball predicted on the basis of the relationship.

6. The swing diagnosis apparatus according to claim 1,

wherein the level calculation section calculates the level on the basis of a speed of the ball hitting portion at impact.

7. The swing diagnosis apparatus according to claim 6,

wherein the level calculation section calculates the level according to the speed.

8. The swing diagnosis apparatus according to claim 1, further comprising:

a display section that displays the level calculated by the level calculation section.

9. The swing diagnosis apparatus according to claim 1,

wherein the level is a score.

10. A swing diagnosis system comprising:

the swing diagnosis apparatus according to claim 1; and

an inertial sensor,

wherein the level calculation section calculates a level on the basis of outputs from the inertial sensor.

11. A swing diagnosis method comprising:

a procedure of calculating a level on the basis of a relationship between a rotation angle about a rotation axis of an exercise appliance at a predetermined timing between the time of starting a backswing and the time of impact with a longitudinal direction of the exercise appliance as the rotation axis, and an inclination of a ball hitting portion of the exercise appliance at impact.

12. A recording medium recording a swing diagnosis program causing a computer to execute:

a procedure of calculating a level on the basis of a relationship between a rotation angle about a rotation axis of an exercise appliance at a predetermined timing between the time of starting a backswing and the time of impact with a longitudinal direction of the exercise appliance as the rotation axis, and an inclination of a ball hitting portion of the exercise appliance at impact.

13. A swing diagnosis apparatus:

calculating a level on the basis of a relationship between a rotation angle about a rotation axis of an exercise appliance at a predetermined timing between the time of starting a backswing and the time of impact with a longitudinal direction of the exercise appliance as the rotation axis, and an inclination of a ball hitting portion of the exercise appliance at impact.

14. The swing diagnosis apparatus according to claim 13,

wherein the rotation angle is an angle by which the exercise appliance is rotated about the rotation axis from the time of starting the backswing to the predetermined timing.

15. The swing diagnosis apparatus according to claim 13,

wherein the predetermined timing is the time at which the backswing transitions to a downswing.

16. The swing diagnosis apparatus according to claim 13,

wherein the inclination of the ball hitting portion is an angle formed between an outer edge of a hitting surface of the ball hitting portion and a virtual straight line orthogonal to a target hit ball direction in a plan view.

17. The swing diagnosis apparatus according to claim 13,

wherein the level is calculated according to a curved state of a hit ball predicted on the basis of the relationship.

18. The swing diagnosis apparatus according to claim 13,

wherein the level is calculated on the basis of a speed of the ball hitting portion at impact.

19. The swing diagnosis apparatus according to claim 18,

wherein the level is calculated according to the speed.

20. The swing diagnosis apparatus according to claim 13,

wherein the calculated level is displayed.

21. The swing diagnosis apparatus according to claim 13,

wherein the level is a score.
