Method for matching a golfer with a particular club style
View Patent ↗A method is disclosed for matching a test golfer with a particular golf club selected from a group of golf clubs having a plurality of styles. The method utilizes data set derived in an initial procedure in which the club style preferences for each of a large number of pre-test golfers is recorded and correlated with a set of performance parameters for the golf swings of such pre-test golfers. This data enables the pre-test golfers to be classified into subgroups, in which golfers within the same subgroup generally prefer the same club style and golfers in different subgroups generally prefer different club styles. After this data set has been established, the test golfer takes a golf swing with a golf club, while performance parameters for the swing are measured. Based on the measured performance parameters and the previously established data set, the test golfer is classified according to swing type, and the optimum golf-club is then selected from the plurality of styles of golf clubs.
1. A method comprising:
determining a plurality of swing performance parameters for each of a plurality of test golfers, the plurality of swing performance parameters being determined from measurements obtained while each test golfer successively swings a plurality of dissimilar golf clubs;
receiving from each of the plurality of test golfers the test golfer's golf club preference from among the plurality of dissimilar golf clubs;
correlating the test golfers' measured swing performance parameters and golf club preferences; and
storing on a storage device a data set indicative of the correlation between the test golfers' measured swing performance parameters and golf club preferences.
2. The method of claim 1 , wherein the golf club preference for each of the plurality of test golfers is based on which golf club provided the best performance for that particular test golfer.
3. The method of claim 1 , wherein at least two golf clubs within the plurality of dissimilar golf clubs each has at least one different performance characteristic.
4. The method of claim 3 , wherein at least two golf clubs within the plurality of dissimilar golf clubs each has a different shaft weight configuration.
5. The method of claim 4 , wherein the shaft weight configuration comprises a total shaft weight or a shaft weight distribution.
6. The method of claim 3 , wherein at least two golf clubs within the plurality of dissimilar golf clubs each has a different shaft flex.
7. The method of claim 1 , wherein each of the plurality of test golfers is provided with at least two golf club groups.
8. The method of claim 7 , wherein golf clubs in the same golf club group have a similar shaft weight configuration, and wherein golf clubs in different golf club groups have dissimilar shaft weight configurations.
9. The method of claim 8 , wherein the shaft weight configuration comprises a total shaft weight or a shaft weight distribution.
10. The method of claim 7 , wherein golf clubs in the same golf club group have a similar shaft flex, and wherein golf clubs in different golf club groups have dissimilar shaft flexes.
11. The method of claim 1 , wherein each of the plurality of test golfers is provided with a first golf club group, a second golf club group, and a third golf club group.
12. The method of claim 11 , wherein each golf club within the first golf club group has a first total shaft weight, each golf club within the second golf club group has a second total shaft weight, and each golf club within the third golf club group has a third total shaft weight.
13. The method of claim 12 , wherein the first total shaft weight is less than the second total shaft weight, and the second total shaft weight is less than the third total shaft weight.
14. The method of claim 11 , wherein each golf club within the first golf club group has a first shaft weight distribution, each golf club within the second golf club group has a second shaft weight distribution, and each golf club within the third golf club group has a third shaft weight distribution, and wherein the first, second and third shaft weight distributions are dissimilar.
15. The method of claim 11 , wherein the first golf club group comprises a first golf club having a first shaft flex, a second golf club having a second shaft flex, and a third golf club having a third shaft flex, wherein the third shaft flex is stiffer than the second shaft flex, and the second shaft flex is stiffer than the first shaft flex.
16. The method of claim 11 , wherein the second golf club group comprises a fourth golf club having a first shaft flex and a fifth golf club having a second shaft flex, and wherein the second shaft flex is stiffer than the first shaft flex.
17. The method of claim 13 , wherein the third golf club group comprises a sixth golf club having a first shaft flex, a seventh golf club having a second shaft flex, and an eighth golf club having a third shaft flex, wherein the third shaft flex is stiffer than the second shaft flex and the second shat flex is stiffer than the first shaft flex.
18. The method of claim 1 , wherein a three dimensional motion analysis system is used to measure the one or more swing performance parameters.
19. The method of claim 1 , wherein the measurements include a time duration from the start of a test golfer's downswing to the time of peak hand speed, or a minimum speed of a test golfer's hands during a transition from the backswing to the downswing, or hand acceleration, or hand position during the swing, or timing and magnitude of wrist uncocking and hand rotation, or combinations thereof.
20. The method of claim 1 , wherein correlating comprises classifying the test golfers into a plurality of golfer classification groups, each golfer classification group defined by a range of values within each of a plurality of measured swing performance parameters.
21. The method of claim 20 , wherein golfers within a golfer classification group generally prefer golf clubs with the same performance characteristics.
22. The method of claim 20 , wherein correlating further comprises determining a relationship between each of the golfer classification groups and at least one golf club performance characteristic.
23. The method of claim 22 , wherein the golf club performance characteristic comprises a shaft weight configuration.
24. The method of claim 23 , wherein shaft weight corresponds to total shaft weight.
25. The method of claim 23 , wherein shaft weight corresponds to shaft weight distribution.
26. The method of claim 23 , wherein the at least one golf club performance characteristic comprises shaft flex.
27. The method of claim 20 , wherein correlating further comprises determining a relationship between each of the golfer classification groups and at least one preferred golf club.
28. The method of claim 1 , wherein correlating comprises classifying the test golfers into a plurality of golfer classification groups, each golfer classification group defined by a club head speed range, a maximum shaft deflection range, a time of peak hand speed range, and a minimum hand speed range.
29. The method of claim 28 , wherein correlating further comprises determining a relationship between each of the golfer classification groups, a shaft weight, and a shaft flex.
30. The method of claim 28 , wherein correlating further comprises determining a relationship between each of the golfer classification groups and at least one preferred golf club.
31. The method of claim 1 , wherein correlating further comprises performing a statistical cluster analysis of the measured plurality of swing performance parameters and the golfers' golf club preferences.
32. The method of claim 1 , wherein the measurements comprise at least one measurement of the test golfer's hand motions during the test golfer's golf swing.
