  FIG. 2 is a conceptual diagram showing the measurement state of the present embodiment. As shown in FIG. 2, the measuring means 2 measures the swing behavior when the golfer G swings the golf club C, particularly the behavior of the head H when hitting the golf ball B. The measuring unit 2 can measure, for example, the head speed HS and the blow angle θ of the golf club C.

  3A and 3B show the swing path So of the head H when the golf ball B is hit. The head speed HS is the speed of the head H at the moment when the golfer G hits the golf ball B. The blow angle θ is an angle with respect to the tangent line of the swing path So of the head H and the horizontal plane HP at the moment of hitting the golf ball B.

  The swing path So of FIG. 3A is a hitting method in which the lowest point LP is ahead of the hitting position of the golf ball B in the hitting direction, and is called down blow. The blow angle θ at this time is measured as negative value data D by the measuring means 2, for example.

  The swing trajectory So of FIG. 3B is a hitting method in which the lowest point LP is behind the hitting point of the golf ball B in the hitting direction, and is called upper blow. The blow angle θ at this time is measured as positive value data D by the measuring means 2, for example.

  In this specification, the hitting method in which the blow angle θ is within ± 0.5 degrees is defined as level blow.

  As shown in FIG. 2, it is preferable that the measuring means 2 is mounted on the golf club C, for example. Such a measuring means 2 can measure without specifying a measuring place and is easy to carry. Note that the measuring unit 2 may include an imaging unit such as a high-speed camera, for example. In this case, it is desirable that the golf club C is provided with a marker so that the analysis can be easily performed.

  For example, a computer is used as the analysis means 3. Instead of the computer, a small portable device such as a tablet or a multi-function mobile phone may be used. Data D obtained by the measuring means 2 is input to the analyzing means 3. The data D is input through, for example, wired, wireless, or various storage media.

  As shown in FIG. 1, the analysis unit 3 performs analysis based on the data D input from the measurement unit 2 and a predetermined processing procedure. The analysis means 3 of this embodiment includes a processing means 4 to which data D is input, an input means 5 for inputting information from outside, and an output means 6 for outputting analysis results.

  The processing means 4 is classified into a calculation means 7 for calculating the data D according to a predetermined procedure, and a determination means 8 for classifying the golfer G according to the predetermined processing procedure based on the data D and the calculated result. The golfer G includes selection means 9 for selecting the type of the golf club C.

  The input unit 5 is preferably a unit capable of inputting arbitrary information such as a keyboard, a mouse, or a touch panel. The output means 6 is preferably a means capable of displaying visual information such as a monitor or a printer.

  FIG. 4 shows a flowchart of the golfer classification method. As shown in FIG. 4, in the golfer classification method of the present embodiment, the golfer G is classified based on the swing behavior of the golfer G.

  In the golfer classification method of this embodiment, first, the measurement unit 2 performs a first measurement step S1 for measuring the behavior of the head H when the golfer G hits the golf ball B with the predetermined golf club C. In the first measurement step S1 of the present embodiment, the first head speed HS1 when the golfer G hits the golf ball B with the short iron C1 is measured. The short iron C1 of the present embodiment is an iron having a loft angle larger than 37 degrees and a club length L1 shorter than 37 inches, for example. The first measurement step S1 may measure one swing, or measure a plurality of swings and calculate an average value thereof.

  Next, a second measuring step S2 for measuring the behavior of the head H when the golfer G hits the golf ball B with a golf club C different from the golf club C measured in the first measuring step S1 by the measuring means 2. Is done. In the second measurement step S2 of the present embodiment, the second head speed HS2 and the blow angle θ when the golfer G hits the golf ball B with the long iron C2 are measured. The long iron C2 of the present embodiment is, for example, an iron having a loft angle smaller than 25 degrees and a club length L2 of 38 inches or more. The second measurement step S2 may measure one swing, or measure a plurality of swings and calculate an average value thereof.

  Next, the behavior of the head H when the golfer G hits the golf ball B with a golf club C of a type different from the golf club C measured in the first measuring step S1 and the second measuring step S2 by the measuring means 2. A third measurement step S3 for measuring is performed. In the third measurement step S3 of the present embodiment, a third measurement step S3 for measuring the third head speed HS3 when the golfer G hits the golf ball B with the non-iron type club C3 is performed. The non-iron type club C3 of the present embodiment is a utility whose club length L3 is close to the club length L2 of the long iron C2, for example. The non-iron type club C3 may be a fairway wood.

  The third measurement step S3 may measure a single swing, or measure a plurality of swings and calculate an average value thereof. For example, the third measurement step S3 may be performed only when the golfer G is classified into the second down blow group described later by the determination unit 8.

  In addition, the above-mentioned 1st measurement process S1, 2nd measurement process S2, and 3rd measurement process S3 do not need to be measured in this order, and a measurement order is not specifically limited. Each measurement process S1-S3 may be performed first, for example, the second measurement process S2.

  Next, a calculation step S4 for calculating a head speed ratio HS2 / HS1, which is a ratio between the first head speed HS1 and the second head speed HS2, is performed by the calculation means 7.

  Next, a determination step S5 for classifying the golfer G is performed by the determination means 8. FIG. 5 is a flowchart illustrating an example of the determination step S5. As shown in FIG. 5, in the determination step S5 of the present embodiment, first, the golfer G is based on the blow angle θ when the golf ball B is hit with the long iron C2 and the predetermined first threshold T1. 1st determination process S51 which classifies is performed. It is desirable that the first threshold T1 is input to the determination unit 8 by the input unit 5 in advance.

  In 1st determination process S51 of this embodiment, the golfer G can be classify | categorized into a down blow group and a non-down blow group by setting 1st threshold value T1 to -0.5 degree | times, for example. That is, in the first determination step S51, the golfer G who performs downblow is classified into a downblow group. In the first determination step S51, the golfer G who performs the level blow and the upper blow is classified into a non-down blow group. In such 1st determination process S51, the information which identifies which group it belongs to is added to the golfer information for identifying each golfer G.

  When the golfer G is classified into the non-down blow group in the first determination step S51, the determination step S5 ends here.

  When the golfer G is classified into the down blow group in the first determination step S51, in the determination step S5, the determination unit 8 determines whether the golfer G is down based on the head speed ratio HS2 / HS1 and the predetermined second threshold value T2. A second determination step S52 for further classifying the blow group golfers G is performed. The second threshold T2 is preferably determined based on a club total length ratio L2 / L1, which is a ratio of the club length L1 of the short iron C1 and the club length L2 of the long iron C2. Such a second threshold value T2 can be an index for confirming an improvement in the head speed HS utilizing the club length. The club lengths L1 and L2 are preferably input to the determination unit 8 by the input unit 5 in advance.

  The second threshold value T2 is desirably determined within a range of ± 3% of the club total length ratio L2 / L1, that is, a range of 97% to 103% of the club total length ratio L2 / L1, for example. When the second threshold T2 is smaller than 97% of the club total length ratio L2 / L1, there is a possibility that improvement in the head speed HS utilizing the club length cannot be confirmed. If the second threshold T2 is larger than 103% of the club total length ratio L2 / L1, the golfer G will be asked to improve the head speed HS excessively, and there is a possibility that appropriate classification cannot be performed. The second threshold T2 is more preferably in the range of 98% to 100% of the club total length ratio L2 / L1. Such a second threshold value T2 can be an index for classifying the golfer G having a long iron C2 with few miss shots and a high probability of achieving a desired flight distance as the first down blow group.

  In the second determination step S52 of this embodiment, the golfer G of the down blow group is classified into a first down blow group with a large head speed ratio HS2 / HS1 and a second down blow group with a small head speed ratio HS2 / HS1. Can do. That is, in the second determination step S52, the golfer G whose head speed ratio HS2 / HS1 is larger than the second threshold value T2 is classified into the first down blow group. In the second determination step S52, the golfer G having the head speed ratio HS2 / HS1 of the second threshold value T2 or less is classified into the second down blow group. In such 2nd determination process S52, the information which identifies to which group it belongs to the golfer information for identifying each golfer G is added.

  When the golfer G is classified into the first down blow group in the second determination step S52, the determination step S5 ends here.

  When the golfer G is classified into the second down blow group in the second determination step S52, in the determination step S5, based on the third head speed HS3 and the third threshold T3 of the non-iron type club C3 by the determination means 8. Then, a third determination step S53 for further classifying the golfers G of the second down blow group is performed. The third threshold T3 is determined based on, for example, the second head speed HS2 of the long iron C2. The third threshold value T3 is preferably the second head speed HS2. Such a third threshold value T3 can be an index for classifying golfers G that have a high probability of achieving a desired flight distance in the non-iron type club C3.

  In the third determination step S53 of the present embodiment, the golfer G of the second down blow group is set to have the second non-iron group and the third head speed HS3 whose third head speed HS3 is larger than the third threshold T3 is the third threshold T3. It can be classified into the following second iron group. In such 3rd determination process S53, the information which identifies which group belongs to the golfer information for identifying each golfer G is added.

  In the golfer classification method of the present embodiment, the result of the golfer G being classified in the determination step S5 may be output to the output unit 6, for example. FIG. 6 is a diagram illustrating a classification result of the golfer G. The horizontal axis of FIG. 6 is the head speed ratio HS2 / HS1, and the vertical axis is the blow angle θ. The output means 6 can visually display the group to which the golfer G belongs, for example, by plotting one point of the graph of FIG. The output means 6 visually displays the second non-iron group and the second iron group, for example, by changing the color of the plot in FIG. 6 for the golfer G classified as the second down blow group. be able to.

  FIG. 4 shows a golf club selection method including a selection step S6 for selecting an optimum type of golf club C for the golfer G classified by the above-described golf classification method.

  FIG. 7 is a flowchart showing an example of the selection step S6. As shown in FIG. 7, in the selection step S <b> 6 of the present embodiment, first, a step S <b> 61 is performed in which it is determined whether the golfer G to be selected is classified into a down blow group.

  Next, in step S61, the non-iron type club C3 is selected as the golf club C corresponding to the low iron count of the golfer G not classified into the downblow group, that is, the golfer G of the non-downblow group. Step S62 is performed. The golfer G of the non-downblow group has a high probability of making a miss shot in the long iron C2, so the non-iron type club C3 is selected.

  On the other hand, in step S61, a step S63 for determining whether or not the golfer G is classified into the first down blow group is performed.

  Next, in step S63, a step S64 of selecting the long iron C2 as the golf club C corresponding to the low count of the iron set for the golfer G classified in the first down blow group is performed. The golfer G of the first downblow group is selected to have a long iron C2 with high controllability because downblow and an improvement in the head speed HS utilizing the long overall length of the club are recognized.

  On the other hand, in step S63, it is determined whether or not the golfer G that is not classified into the first down blow group, that is, the golfer G in the second down blow group, is classified into the second non-iron group. .

  Next, in step S65, a step S62 of selecting a non-iron type club C3 as a golf club C corresponding to a low count of the iron set is performed for the golfer G classified in the second non-iron group. The golfer G of the second non-iron group is selected as the non-iron type club C3 because the non-iron type club C3 is improved in the head speed HS utilizing the long overall length of the club compared to the long iron C2. .

  On the other hand, in step S65, the long iron C2 is selected as the golf club C corresponding to the low iron count of the golfer G not classified into the second non-iron group, that is, the golfer G of the second iron group. S64 is performed. The golfer G of the second iron group has high controllability in both the long iron C2 and the non-iron-type club C3 because the improvement in the head speed HS utilizing the long overall length of the club is not recognized, but it is a down blow. Long iron C2 is selected.

  In the golf club selection method, the type of the golf club C selected in the selection step S6 is output to the output means 6, for example, and the process ends.

  Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and can be implemented with various modifications.

  Eight golfers G1 to G8 were classified based on the golfer classification method of the present embodiment. When each golfer swings with a golf club described in the following common specifications, the swing behavior was measured. The measurement was performed 10 times for one golf club, and the average value was obtained.

<Common specifications>
